1. What are the advantages and disadvantages of Solar lamps?
Advantages of Solar street lights
1. Energy -saving and environmental protection -Solar street lights use natural light to reduce the consumption of electrical energy; Solar street lights are polluted and radiated, which is in line with modern green environmental protection concepts.
2. Safe and durability Traditional lighting street lights can be transformed through electrical energy, which may cause hidden safety hazards due to construction quality, aging materials, and abnormal power supply.The Solar street lights do not use AC power, and the battery uses the battery to absorb solar energy and convert low -voltage DC into optical energy. There is no hidden safety hazard.At present, the production technology of most Solar battery components is sufficient to ensure that the performance will not decrease for more than 10 years. Solar battery components can generate electricity for 25 years or longer.

3. Low high -tech content and low maintenance costs -Solar street lights are controlled by intelligent controllers, which can be based on the natural brightness of the sky and the brightness required by people in various environments within 1 day.In remote areas far from town, the cost of maintaining or repairing conventional power generation, transmission, street lights and other equipment is high.Solar street lights only need cyclical inspection and little maintenance workload, and its maintenance costs are much less than conventional power generation systems.
4. Install component building blocks, independent power supply -flexible and convenient installation, so that users can choose and adjust the capacity of Solar street lights according to their needs.The Solar street lights Running away from the net have the autonomy and flexibility of power supply.
Disadvantages 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 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. Lowlire and cost -effectiveness of components -the price of batteries and controllers is high, and the battery is not durable. It must be replaced regularly. The service life of the controller is generally only 3 years; the reliability is low.
5. The maintenance of Solar street lights is difficult. The quality of the heat island effect of the battery board cannot be controlled and detected. The life cycle is not guaranteed, and the control management cannot be uniformly performed.There may be different lighting situations; the range of light is narrow. The Solar street lights currently used by the China Municipal engineering Association are inspected and determined on the spot. The general illumination range is 6-7m.The needs of the main road.
2. What are the types of Solar lamps?
1. home lighting
Compared with ordinary LED lights, Solar lamps are built into lithium batteries or lead-acid batteries, which are connected to one or more Solar panels to charge it. Generally, the charging time is about 8 hours, and the use time is 8-24 hours.Generally with charging or remote control functions, the appearance is different according to user needs.
2. Signal light
The role of navigation, aviation and land Traffic signal lights is very important. Many local power grids cannot supply power, while Solar signal Lights can solve the problem of power supply. The light source is mainly based on small particles.Good economic and social benefits have been achieved.
3, lawn Lights
Solar lawn Lights, light source power 0, 1 ~ 1W, generally use small particles to light emitting diode (LED) as the main light source.The power of Solar panels is 0, 5 ~ 3W, and can use two batteries such as 1 and 2V nickel batteries.
4, Landscape light
Landscape lighting Solar lights are used in squares, parks, green spaces and other places. Various shapes of small -power LED dot light sources and wire light sources are used. There are also cold and cathode -shaped Lights to beautify the environment.Solar landscape lamps can achieve better landscape lighting effects without destroying green spaces.
5. Make a lamp
Lights used for night orientation instructions, house cards, intersections.The optical flux of the light source is not high, the system configuration requirements are low, and the amount of usage is large.The light source of the identified light can generally use a small -power LED light source or a cold cathode light.
6. street lights
Solar street lights are used in village roads and rural roads. They are one of the main applications of Solar photovoltaic lighting devices.The light source adopted has a small power high -voltage gas discharge (HID) light, fluorescent lamp, low -voltage sodium lamp, and high -power LED.Due to its overall power restrictions, there are not many cases applied to urban main roads.With the complementary with the municipal route, the application of Solar photovoltaic lighting street lights on the main road will increase.
7, insecticidal lamp
It is used in orchards, plantations, parks, lawn and other places.Generally, fluorescence Lights with specific spectrals, more advanced LED purple Lights, and radiating murderous insects through its specific spectrum lines.
8, flashlight
The use of LED as a light source can be used in the wild or emergency.
9, courtyard light
Solar courtyard Lights are used in urban roads, commercial and residential communities, parks, tourist scenic spots, squares and other lighting.You can also change the above -mentioned municipal lighting system to the Solar lighting system according to the needs of the user.
