1. The advantages and disadvantages of Solar street lights

Solar street lights are used to power the light energy through the Solar circuit board to power the lamp. This kind of energy -saving and environmentally friendly street lights are used more and more. Is Solar street lights easy to use?

1. The advantages of Solar street lights

(1) The installation is easier: The initial laying cable of the conventional street lighting project is a very difficult basic project. First, the excavation of the wire ditch, the launch of the wire Tube, the internal pipeline, the earthwork backfill, and the vegetation recovery.Then carry out long -term installation and debugging. If there is any problem with any line, the inspection work is more complicated, and a large area of rework may be required.Strict requirements for terrain and lines, high auxiliary materials and labor costs.The installation of Solar street lights is relatively simple and cheap: When installing solar energy, you don't need to lay complex lines. You only need to make a cement base, and then install the light rod.

(2) Low use cost: The daily use of conventional street lights requires high electricity costs. It is necessary to maintain or replace the lines and other configurations for a long time, and the maintenance cost increases year by year.Solar street lights do not require electricity bills, only one investment is required, and there is basically no maintenance cost in the later period, which has benefited for a long time.

(3) Safety: Conventional street lights have hidden dangers in terms of construction quality, aging materials, abnormal power supply, and conflict of water and electric pipelines: Solar street lights use 12V low -voltage power supply, operate safe and reliable, safe and reliable, no energy saving, no consumption, green, green, green, green, greenEnvironmental protection, easy installation, and automatic control of maintenance exemption.

(4) Energy -saving and environmental protection: Solar street lights use Solar light as the source of energy, without consuming conventional electrical energy, solar energy is inexhaustible clean energy, which is in line with the state's national policy that advocates green, energy saving and environmental protection.

2. The disadvantage of Solar street lights

(1) High cost: The initial investment in Solar street lights is large, and the total cost of a Solar street light is 3 or 4 times that of the same power conventional street lights.

(2) Low energy conversion efficiency: The conversion efficiency of Solar photovoltaic batteries is about 15%to 19%. In theory, the conversion efficiency of silicon Solar cells can reach 25%, but after actual installation, the efficiency may be reduced due to the blocking of the surrounding buildings.Essence

(3) Affected by geographical climatic conditions: Due to relying on the sun to obtain energy, the local geographical climate and weather conditions directly affect the use of street lighting.The rainy days will affect the lighting Lights, causing the illuminance or brightness to meet the requirements of the national standard, and even the Lights appear. Because the light is insufficient during the day, the light time at night is too short.

(4) Low life and cost -effectiveness of components: The price of batteries and controllers is high, and the battery is not durable enough. It must be replaced regularly.

(5) The brightness is relatively low: Compared with the city circuit light, Solar street lights are usually half -power or lower power, low brightness, and the general illumination range is 6-7m.The need for roads and main roads.

2. What road is suitable for Solar street lights

The advantages and disadvantages of Solar street lights are obvious. When used, it can avoid strengths and avoid weaknesses, so that Solar street lights can better play.Generally suitable for installing Solar street lights:

1. Highway street lighting in rural areas, towns and villages

Solar street lights use LED street lights. The advantages of environmental protection and energy saving, low maintenance costs, and non -municipal film interruptions have made rural Solar street lights a landscape of new rural areas.

2. Urban squares, parking lots, school playgrounds, workers' green space, Park lighting

Large -scale urban street lanterns need long -term lighting to consume a large amount of city electricity.Solar street lights use LED street lamp heads, such as energy saving and power saving.Therefore, replacing the city circuit Lights of these places with Solar street lights is a very effective way of energy saving.

3. lighting of golf stadium, seaside bath, high -end villa area and other lighting

The lighting of golf courses, seaside baths, and high -end villa areas often requires Landscape light decoration. Now the Landscape lights can also be powered by Solar panels. The Solar landscape street lights produced are perfectly combined with technology and art, highlighting the beauty of the times.

4. Highway warning signs, bridge street light power replacement

Highway warning signs and bridge street lights replace them into Solar street light products, which can continue to effectively supply power on highway warning signs and bridge street lights, and do not need to maintain it frequently, saving a lot of maintenance costs.

1. What is the sky -to -scallion?

Skywharma cannon, also known as Outdoor Shading sky screen, is a telescopic canopy for professional supporting applications on the top Outdoor. It is very suitable for the outer sunshade of various glass sunshine roofs and lighting roofs, atrium, patio and open -air balcony.Various indoor Shading products in glass rooms can significantly reduce the indoor temperature, thereby achieving an energy saving effect.It can also directly replace the Steel Structure Sunshine room and acrylic sunboard engineering project, which has more flexible and multi -purpose functions.It is now widely used in Lu.

2. The use of the sky -to -scallop cannon is not very useful

In the Shading world, the building Shading system is divided into two ways: Outdoor and Outdoor.In the past, the Shading system was generally designed in the household. In fact, the Outdoor Shading of the building was more scientific than the Shading in the building household, and the Shading effect played was better.

What is the difference between indoor and Outdoor sun Shading?The indoor Shading is to put the sky -to -Shading in the window. The canopy forms a Shading pitch visually. In fact, the heat has entered the room to produce greenhouse effects in the glass, which inevitably accumulates the indoor heat.Air conditioning; Outdoor Shading is not affected by this kind of greenhouse. It is to put the shade fabric and aluminum alloy outside the glass, blocking the light, but also breathing and reflection of calories through Shading fabrics.Good energy saving effect.Data show that 80%of the heat in the households will enter the room through the in -house Shading, while the Outdoor Shading is only 20%of the calories into the room.It can be seen that the use of the sky -to -scaling canopy is still relatively large.

1. Rinse clean water, drip a few drops of tableware and detergent on the endoscopy after drying, do not mix the water; make the endoscopy full (do not rub it with your hand), put it for a few hours or overnight, and then spend the night, and then spend the night, and then spend the night, and then spend the night.Rinse a little with water to no bubbles.After processing this way, it can generally be controlled for 2-6 hours.There is a surfactant in the cleaning of the detergent, which can change the surface tension of the water, so that the fog drip quickly condenses into a large water droplet.

2. Lick the endoscopy with your tongue. It is said that professional athletes do so.The advantage is that it is very convenient to take it without cost, and it is not necessary to say the disadvantage.Because there is a certain amount of oil in the mouth, and the oil can play a hydrophobic effect, the water mist on the Swimming goggles quickly condenses into large water droplets.

3. Apply the endoscopic surface with medical Vaselin; or fresh egg white to apply the endoscopic surface, dry it after drying.The disadvantage is that it is easy to accumulate dirt after 1 or 2 months.

4. Shampooing fragrances have surfactants and conditioning agents (category with a lot of silicon oil), where silicon oil is commonly used, so the relative effect is better.

2. The anti -fog performance of the general swimming moster will fail at 80 degrees Celsius.Therefore, you should avoid letting the Swimming goggles contact the thermal source, and avoid placing the Swimming goggles in the storage box irradiated by the sun.

3. The anti -fog performance of the standard swimming moster can last for more than 100 hours. If the mirror surface is found when it is just used, most of the reasons are that the user swims in unclean or oily water, so that the lens anti -fog surface is attached to a one.Layer oil dirt is blocked by the anti -fog effect. At this time, as long as the oil dirt on the lens with a neutralized lens is used to restore the anti -fog performance of the goggles.

4. Instructions for the use of anti -fog function: Anti -fog agent and anti -fog film are all hydrophilic substances. Therefore, when consumers use Swimming goggles for the first time, they should rinse the Swimming goggles in orderPerformance is fully played.

1. Is the Camping light waterproof?

Camping lights have a certain waterproof ability.

Because at the time of Camping, some camp environment is very humid, and the next day it is like a rain that was rained for a night, so the Camping light requires a certain waterproof ability;The Lights are generally Hanging under the sky curtain or inside the Tent. Only a small amount of water will be dipped. The waterproof performance is too strong and it will not play a sufficient effect.

2. Can the Camping light be drizzled with rain?

The waterproof performance of Camping lights is very important. After all, it is used in the wild environment. It may suddenly rain at night. Therefore, the Camping light needs to have a certain waterproof ability. So what is the waterproof performance of Camping lights?Can it rain?

Therefore, under normal circumstances, the Camping light cannot be used directly in the rain. There is no big problem with a small amount of rain. If it is used in the rain, it is likely to damage.

3. Wild Camping lights and waterproof levelgenerallyHow much

When going out to Camping, sometimes the environment is very humid, and even when it is raining. At this time, the waterproof performance of Camping lights is particularly important.The waterproof performance of Camping lights is generally divided by waterproof level.

The waterproof performance of the lamps is usually measured by the IPX waterproof level standard. From IPX-0 to IPX-8 to nine Levels. IPX-0 level means no waterproof protection. IPX-8 Levels can guarantee that the water surface is immersed in the water surface of 1.5 ~ 30 meters.For 30 minutes, the performance is not affected and does not leak.Camping lights are outdoor lamps. Generally, IPX-4 Levels are sufficient. It can eliminate the harmful effects of splashing droplets from different directions. It is the basis for using outside accounts and is enough to cope with Outdoor humid environment.Level can reach IPX-5 level.
