The cost of solar street lights is certainly a major factor affecting their price. The cost consists of the sum of the various components that make up a solar street light, generally including LED light source, photovoltaic modules, batteries, street light controllers, solar street light poles, and auxiliary wiring materials. The price of each component will determine the final price of the solar street light.
LED lamps are the primary choice for solar street lights. The advantages of LED street lights will not be detailed here. The main components of LED light sources include:
1. Lamp housing: There are ordinary lamps modified and die-cast whole shells. The former has poor heat dissipation and is suitable for small power light sources, while the latter has good heat dissipation and is suitable for high power light sources.
2. Chip: The chip determines the brightness, light decay, efficiency, and power of the LED, making it an important factor. The quality of chips on the market varies. Reputable manufacturers generally test their chips and choose products that have good quality and cost-effectiveness. Common chips include Bridgelux and Jingyuan.
3. Constant current source: Its function is to maintain a constant current in the circuit. LED street lights require a stable circuit current. The quality of the constant current source affects the quality of the light source, ensuring stable current can protect the life of the light source and prevent chip burnout.
Other small components can also have varying impacts on the luminaire, such as the thickness and quality of the aluminum substrate. This can lead to a significant price difference for lights with the same power; reputable manufacturers guarantee quality which results in higher costs and consequently higher prices.
