There are many types of street lamps. Different lighting technologies are suitable for different needs. The fundamental purpose is to design a high -efficiency electronic energy -saving street light with long life, low power consumption, high power factor, and small current harmonic content.

2. What is good for street lights

The street lighting is generally used for high -pressure sodium lamps,Metal halide lamp is also a common source of street lights.From the perspective of lighting, incandescent lamps are the best, but the light flux is low and the light effect is poor.fluorescent lampThe same is the fluorescent lamp. The light emitting principle depends on the gas electrical ionization to stimulate fluorescent powder to light up. Its color rendering is low, but the light flux and the light effect are much better than the incandescent lamp. The neon Lights are almost no other benefits except for good -looking.Extremely low, you cannot do special lighting Lights; the performance of metal halide lamps is very good, especially its power can be made very much than other lamps; LED lights are highly efficient and energy -saving and environmentally friendly, but there are certain certainty.Technical defects.Therefore, in general, it is more appropriate to use metal halide lamps or LED street lights now.

What is the difference between street lights and Landscape lights

1Different height

The difference between street lights and Landscape lights is mainly reflected in the height. The conventional height of street lights is6-12Mi, there are also some routine heights of some street lights are6-20rice.But the general height of Landscape lights is3-6Mi, this is because Landscape lights are ornamental. You do nt need to do too high. The higher the materials you need, the more expensive the cost.

2Different lighting power

Because the street lights are to provide sufficient illuminance, their lighting power is generally large, generally in250-400WWithin the range, the specific power is considered according to the width of the road, the surrounding trees, the height of the light rod, and whether it affects the surrounding residents.

Landscape lights are relatively small, generally80-150WIt may also be smaller, because the landscape lamp has a basic lighting effect. Its biggest effect is to provide strong ornamental. Its light source power can reflect the overall shape of the lamp.Too bright.

3Different applications

street lights are generally used in the main roads, secondary roads, urban squares, communities and other places in cities or villages. lighting needs are generally relatively large.

Landscape lights are generally installed in independent areas, such as parks, gardens, high -end communities, commercial pedestrian streets and leisure squares. Landscape lights are also used in many tourist attractions.

4Different functions

The main role of road Lights is lighting, which must be able to provide pedestrians and vehicles with better lighting.But Landscape lights only need basic lighting. The most important thing is viewing, which is used to decorate the surrounding environment and create an atmosphere.

The shape of the street lights is not so diverse, and there are generally several types.But the Landscape lights have a lot of shapes, very casual and unrestrained.It can be customized according to the surrounding environment and special reasons.

Classification of Outdoor device lighting

1. Industrial traffic venue lighting

Including the lighting of the dock, railway station, freight venue, loading and unloading stations, airfields, warehouses, public engineering and construction sites to ensure night safety and effective work.

The industrial transportation venue of the device lighting equipment can be divided into two types in terms of light distribution:

One is the site that requires a good level (surface) illuminance. The main installation of the chandeliers with better lighting functions, and the installation principles require the installation principles of the field lighting device with level (surface) illuminance.

The other is a venue that requires a high vertical (surface) illuminance. It can be installed with pan -light Lights (see light fixtures) on large spacing columns or high towers.installation principles.

2. sports venue lighting

It mainly refers to the lighting of various sports venues, such as football fields, tennis courts, shooting grounds, golf courses, etc.When choosing a lighting equipment, the visual requirements of various sports are performed for specific analysis. For example, the shooting field is high. At the same time, for the sake of safety, general lighting with soft light at the launch place and the target.

In the large sports field, the distance between the audience and the athletes requires a higher degree of illumination.Although there are not many audiences in the tennis venue, because the speed of tennis in the game is fast and the requirements are high.In addition, the selected lighting equipment cannot generate dispersion and flash effects.The stadiums surrounding the stands are generally used to install lighting equipment on high towers.This method can avoid glare, but the cost is higher.Smaller stadiums generally use lower -cost side Lights, which can be installed along the sides of the site with 8 to 20 meters of lighthouse.The lighting sources of the stadium should be metal halide lamps.

3. Outdoor lighting of other buildings

Including gas stations, sales venues, billboards, office building lighting, and the appearance lighting of plant buildings (see the night scenery of the building).

[Principles of Affective Lights] What are the characteristics of the working principle of non -polar lamp?

What is the working principle of non -polar lamp

The inflexible lamp consists of three parts: high -frequency generator, coupling device, and Light bulb. The working principle is: coupling the energy of high -frequency electromagnetic field into the Light bulb by induction, so that the gas in the bulb is penetrated and forms a plasma.When the atom returns the base state, it radiates 254nm ultraviolet rays. The fluorescent powder in the Light bulb is excited by ultraviolet rays and emits visible light.

What are the characteristics of non -polar lamp

1. There are no filaments and electrodes in the bulb, and the product life is more than 60,000 hours.

2. High emitting efficiency, high -frequency non -polar lamp 80lm/w, low -frequency non -polar lamp 85LM/W.

3. The color rendering index is more than 80 or more, and the high -quality triple -based fluorescent powder is used.

4. Wide voltage work, the voltage can work normally at 185V-255V.

7, instant startup and then starting time is less than 0.5 seconds.

8. The starting temperature is low, the adaptation temperature range is large, minus 25 degrees, which can be started and work normally.

9. The power factor can be as high as 0.95.

10. Safety and reliability, green environmental protection, truly realized exemption and replacement.

High -frequency explosion -proof non -polar lamp composition

High -frequency generator

The high -frequency generator mainly includes an equivalent circuit of oscillator, filter, rectifier, switching device, matching network, driving coil and arc.It provides a high -frequency energy to stimulate and maintain gas discharge in the bulb.The high -frequency generator must have a very stable oscillating source and filter circuit. At the same time, it also has a high power factor and a low harmonic content.

All electronic components are installed in an aluminum power box, which has dual functions: shielding radio frequency interference and heat transmission to ensure the long life of the electronic device.The output frequency of high -frequency generator is 2.65MHz.

Each high -frequency generator must be combined with the same type lamp and coupler.If this basic criterion is violated, the components of the lamp will be destroyed or the electromagnetic interference will be generated.

Coupler

The coupling device is a device that combines energy from the high -frequency generator through the coil to the bulb.It consists of magnetic core, high temperature line, heat conduction rod, winding rack, base, transition parts and coaxial cables.

The role of magnetic core and high temperature line is to produce high -frequency magnetic fields.Through the heating rod in the middle, the excess thermal energy and discharge generated by the coil are transmitted to the outside through the aluminum base.There are two functions of the base: one is to ensure the connection between the bulb and the coupler; the other is to pass the excess heat to the heat sink. This heat sink must be part of the lamp.Connect with the Lights with the screws.

Connect the coupler to the high -frequency generator through the coaxial cable.The coaxial cable is connected to the coupler, and the high -frequency generator can be disassembled through the screw, the purpose is to facilitate the connection with the lamp.

The copper heating rod is extended to the center of the bulb to dissipate the iron oxygen magnetic core. There are two layers of high -temperature lines on the winding frame: one layer of conveying current, and the other layer is wrapped in the primary coil, but only one end is connected to the coil.In this way, the electric field of the second coil offsets the electric field generated by the first coil. In this way, the interference of the public mode terminal voltage is reduced to a lower value.

Light bulb

The bulb is mainly a glass bulb, which is mainly composed of bubbles, inner Tube, mercury, auxiliary mercury, etc. with a protective film and triple -color fluorescent powder, and the lamp head. It is filled with low -pressure mercury and inert buffer gases inside.

There is a glass inner Tube in the middle of the bulb, and the inner Tube is the coupling device.Through the plastic lamp head, the bulb is connected to the coupler.The installation of these two parts is generally only once, because it is a long life lamp. After installing it on the lamp, there is no need to disassemble.But sometimes (for example: at work or afterwards, when you need to change another color light), the light bulbs also need to be removed from the coupling device, but must be cautious.

There are two kinds of mercury in the Wuji fluorescent lamp. The main mercury is located in the short Tube at the bottom of the shell. Once the light is stable, it provides mercury atoms.The auxiliary mercury is placed on a close to the concave cavity, and the net is contacted with the heat discharge heat.Once the power mercury is quickly evaporated from the auxiliary mercury,In 10s, the lamp can reach 80%Light output.When the Lights were turned off, the net was cooled quickly, collecting most of the mercury atoms in the bulb to prepare to start the next start.The main mercury is guaranteed to maintain a stable light output within a wider temperature range.Auxiliary mercury ensures that the output is fast and stable.A protective film was coated in the middle of the fluorescent powder and the bubble shell to light upAfter 60,000 hours, the output of fluorescent powder maintained at about 70% of the beginning.

The use and installation requirements of light bulbs

1) light bulbs are not allowed to be used for a long time under the condition of radiator. Long -term use will cause shortened life, and it cannot work properly in severe cases;On the aluminum plate or other metal materials, 4 screws must be used. The screw must be made of electroplating or other corrosive materials; its role is to emit the calories accumulated in the Light bulb to ensure that the temperature of the Light bulb base is less than 90 degrees Celsius, soThe bulb is in a better temperature range;

3) The leader of the bulb is not allowed to be shortened or extended. It will destroy the resistance matching of high -frequency power and light bulbs, causing efficiency to decrease or damage;

4) The high -frequency power generator and the Light bulb must not be installed on the same metal heat sink, and it should be installed separately.If the conditions are not required to be installed in a metal body (such as street lights, pan -light Lights, etc.), under this condition, the distance between the high -frequency generator and the Light bulb should be pulled away.Status; if the lamp is closed, it is recommended to remove the upper cover of the high -frequency generator to benefit better heat dissipation;

5) When the coupler coaxial cable is connected to the output end of the high -frequency generator, be careful not to reconcile, and it shall not be extended, cut or damaged at will;

6) When the light bulbs are lit or just out, do not use your hand to touch the bulb directly, so as not to bring you discomfort.

In order to meet the requirements of the useless fluorescent lamp, please refer to the following terms to design, use and install the Wuji fluorescent lamp lamps.

lighting installation requirements

1) The fixed device of the bulb and the lamp must be firmly connected and tightly contact to ensure good heat dissipation;

2) Lights and high -frequency generators should be grounded according to the requirements when installation;

3) No matter what kind of lamps are used, the lamp shell must be ground.

1. How to choose lamps on road lighting

Road lightingThe quality depends on:

1. The brightness of road lighting.That is, there is enough strength to ensure that the vehicle drivers and pedestrians can see the situation around the roads on the road, pedestrians, vehicles and roads.

2. The uniformity of road lighting.That is, the distribution should be roughly uniform.

3. The degree of glare interference.That is, effectively controlling the harmful effects of glare on vehicle drivers and pedestrians.

4. The guidance of lighting.That is, proper settings are made according to the conditions of the pavement, so that vehicle drivers and pedestrians can effectively obtain information such as the direction and tilt of the road ahead, which is especially important for many roads and cross -port roads.Reasonable application of lamps can prevent glare.

Common lamps:

Littors for road lighting include high -pressure sodium lamps, low -pressure sodium lamps, polar Lights, gold halogen, fluorescent lamps, new type of Suming street lights, etc.Candidates, high -pressure mercury lamps, and low -pressure sodium lamps have gradually been eliminated due to the performance defects of light sources.Littors should use light energy reasonably to prevent glare.The light emitted by the lighting should be irradiated along the required angle, falling into the specified graphic on the road, the light is evenly distributed, the road surface is large, and the glare is small.In order to reduce glare, light control can be controlled above the maximum light.

2. Road lighting device selection

Lightsourceselectselect

The selection of light sources should comply with the following regulations:

1. Expressway, main roads, secondary roads, and branches should be used for high -pressure sodium Lights;

2. Motor vehicles and pedestrians in the residential area should adopt high -pressure sodium lamps or small -power metal halide lamps;

3. Merchant -vehicle traffic roads with high color recognition requirements for color recognition can be used in the city center and business centers. Metal halide lamps can be used;

4. The sidewalks on both sides of the pedestrian street, the pedestrian roads, and the traffic roads on the commercial area may adopt a small -power metal halide lamp, a fine pipe diameter fluorescent lamp, or a compact fluorescent light.

Road lighting should not use town flow high -pressure mercury lamps and incandescent lamps.

Outdoor lighting lamps and its auxiliary device selection

Motor lane lighting should adopt functional lamps that meet the following regulations:

1. Expressway and main roads must be intercepted or half -light lamps;

2. Half -light lamps should be adopted by the secondary road;

3. The branch road should be half -light lamps.

The non -motorized lanes that are necessary to set up lamps separately should be combined with functionality and decorative lamps that are necessary to set up Lights alone.When the decorative lamps are adopted, the on -light light ratio should not be greater than 25%, and the mechanical strength shall meet the provisions of the current national standard "General Safety Requirements and Experiments of the Lantern Festival" GB7000.1.

When using high rod lighting, according to the characteristics of the site, you should select a pan -light or interception lamp with appropriate power and light distribution.

When a closed road lighting is used, the protection level of the light source cavity should not be lower than IP54.The roads and venues of severe environmental pollution and difficulty in maintaining difficulties should not be lower than IP65.The protection level of the lamp appliance cavity should not be lower than IP43.

Activities or places with high corrosive gases such as acid -base in the air should adopt lamps with good corrosion resistance.

Large bridges such as traffic motor vehicles that are susceptible to vibrations are prone to vibration. The lamps adopted should meet the current national standard "lighting General Safety Requirements and Experiment" GB7000.1.

High -strength gas discharge Lights should be equipped with energy -saving inductors, and light sources with smaller power can be equipped with electronic ballasts.

The installation distance between the high -strength gas discharge lamp, the installation distance between the ballast and the light source should meet the product requirements.

1. What is the principle of induced street lights

The induction street lights can be induced by the use of infrared induction modules and PMW control to detect the thermal radiation of the human body, so that when someone is close to the highlights of the high light, the brightness of the light to weaken the light after leaving, and achieve the effect of saving energy. It is an intelligence. It is an intelligence.street lights.

There is a single -piece control in the induction street light. By adjusting the duty cycle to control the brightness, the lamp beads use environmentally friendly LED lamp beads.The induction distance of the inductive street lights can be selected according to the installation interval of Solar street lights. Even if the distance is far away, the induction is sensitive and the humanization requirements can be met.

2. Introduction to the work process of Solar sensing street lights

1. During the day, there is sunlight to charging. The ideal state is 8-10 hours of charging.

2. At night, the lamps are automatically launched to light up. When someone is passing by, the infrared induction device is triggered, and the light is automatically turned on. The strong light generally lasts 30 seconds.Bright mode.

3. When the person leaves the induction range, the light is automatically turned into a slightly bright mode, and the next time someone approaches the strong bright mode.

3. What are the advantages of induction street lights

1. Energy saving and environmental protection:The advantages of induction street lights are mainly energy saving and environmental protection. Because it is a automatic control product made from infrared technology. When the human body enters the inductive area, the switch will automatically connect the load.After leaving, the delay design will automatically turn off the load after leaving, and it is very good to "people go to the Lights, people leave the Lights", avoiding the waste of energy.

2. Automatic light metering:The switch of induction street lights has an automatic light metering design. When the light is strong during the day, the induction work will be disconnected; and the induction street light has no contact electronic switch, which extends the load life.

3, reliable induction:The use of thyristor lines, high safety, wide induction range, and sensitive induction performance.

4. High cost performance:The induction street lights use full -plastic lamps, which is not easy to deform, discolored, damaged, and has a long service life; and the price of induced street lights is not expensive. Because solar energy is used as a source of electrical energy, the cost of use is not too high.
