How to Judge Quality of Solar Street Lamp Light Source？

Solar street lamp market continue to develop with more than 20%. Many areas still use traditional street lights that consume electricity. The maintenance of the traditional street lights cost a lot and the electricity bills are huge. Solar power are everywhere and clean to use, as long as there is solar power, the street lighting fixtures can be powered up. Lighting is concerned by most people, is the light soft or cold? What is the brightness? LEDs is used by most solar street lamp manufacturers now. It has high lighting efficiency and long lifespan. In this article, we will tell you how to judge the quality of solar street lamp led light source.

1. Determine the CCT of the lamp

When choosing solar street lamps, you must understand the color temperature. In life, the color temperature of ordinary incandescent lamps is about 2800K, the color temperature of halogen lamps is 3400K, the color temperature of daylight fluorescent lamps is about 6500K, the color temperature of warm white fluorescent lamps is about 4500K, and the color temperature of high-pressure sodium lamps is about 2000-2100K. Only after knowing these can you choose a suitable solar street lamp to replace the traditional street lamp. The color temperature of solar led street light is about 5000K, which emits white light, and the color temperature of about 3000K is yellow light or warm white light. In fact, the yellow light or warm white light of about 3000K is more suitable for road lighting, while the color temperature of solar powered street lamps of about 5000K is not suitable for road lighting. Because the color temperature of 5000K makes people visually very cold and dazzling, which leads to excessive visual fatigue. And under this color temperature condition, the human's ability to observe from a distance will also decrease, reducing the driver's driving safety.

2. Check the brightness and whether there is glare

The power of the LED light source determines the brightness. Generally, solar street lamps with higher power will be brighter than lamps with lower power, and the price will be relatively higher. If the solar street lamp will produce glare, it will make people's eyes feel uncomfortable, and it will also reduce the visibility of human eyes. Generally speaking, the brighter the solar street lamp, the more obvious the glare will be. However, professional solar street lamp manufacturers will use special treatments to reduce glare while ensuring the brightness of the street lamps.

3. Check LED chip and heat dissipation performance

LED lights mainly rely on chips to emit light, and different chips have different prices. If you want to choose better quality chips, you can choose imported products. The appearance of the luminaire can determine the effect of the radiator. If the external or internal of the luminaire is made of aluminum, it will have a good check and balance effect on the thermal effect of the luminaire. Because temperature determines the service life of LED lamp beads, solving the thermal effect can effectively extend the service life of LED lamps.

4. Look at the light-emitting angle of the luminaire.

LEDs with different purposes have different light-emitting angles. The common light-emitting angles on the market are 8°, 15°, 25°, 45°, 60°, 90°, 120°. According to the angle, it can be divided into narrow beam, medium beam and wide beam. If you want to achieve better light efficiency, narrow-angle beams should be used. But also according to different needs, choose suitable lamps.

The quality of the solar street light source directly affects whether the solar street light can work normally. It is also the most intuitive basis for people to judge the performance of solar street lights. If you want to know more about other matters of solar street lights, please consult us.
