The characteristics of solar street lights are mainly reflected in those aspects

　　 What functions and characteristics does the solar street light have? In terms of function, it is widely used in road lighting to ensure more safety for the citizens’ night time. Solar street light is a very suitable outdoor road lighting equipment. The products of Changhui solar street light manufacturers have their own characteristics. Below we will explain and explain in detail for you:

　　1. Solar street light source lighting characteristics: This light source is unidirectional without diffusion, ensuring light efficiency. The unidirectional lighting function of the product makes the equipment more widely used;

　　2. The solar street light source has a unique secondary optical design, which irradiates the light of the LED light source to the area that needs to be illuminated, and further improves the light efficiency, so as to achieve the purpose of energy saving. The light efficiency must be based on the special secondary Optical design and design can be realized;

　　3, LED light source efficiency has reached 90-110LM/W, and there is still a lot of room for development, the theoretical value reaches 250lm/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall luminous efficiency of LED light sources is stronger than that of high-pressure sodium lamps; (the overall luminous efficiency is theoretical, in fact, the luminous efficiency of high-pressure sodium lamps above 250W is higher than that of LEDs) ；

　　4. The light color rendering of the LED light source is much higher than that of the high-pressure sodium lamp. The color rendering index of the LED is above 75. From the perspective of visual psychology, the same brightness can be achieved. The illuminance of the LED can be reduced by more than 20% compared with the high-pressure sodium lamp. , The reasonable layout of color rendering index can make solar street lights adapt to more environments for use;

　　5. The light decay of the solar street light source is small, less than 3% a year, and it can still meet the road illumination requirements after 10 years of use, while the high-pressure sodium lamp decays greatly, which has dropped by more than 30% in about a year;

　　6, LED is a low-voltage device, the voltage to drive a single LED is a safe voltage, and the power of a single LED in the product is 1 watt, so it is a safer power supply than the use of high-voltage power supplies, especially suitable for public places. Make the life of solar street lights longer.
