Learn to Judge Quality of Solar Street Light Lamp Beads

The significance of the existence of solar street lights is to illuminate passing pedestrians at night. Solar street lights are composed of many accessories, such as solar panels, smart controllers, batteries, light sources, etc. The light source is the most direct and easiest way to test the quality of solar street lights. Therefore, if you want to ensure the quality of solar street lights, the quality of the light source must pass. However, for the dazzling array of light sources on the market, many friends do not know how to distinguish the pros and cons of the light source. Many illegal businesses use fake and inferior LED light sources to impersonate high-quality imported LED light sources, which greatly harms the interests of customers. So, how should we judge the quality of solar street light sources? The quality of solar street light source mainly depends on the following aspects:

Look at the brightness of the lamps. Generally, the brightness of a high-power LED will be much brighter than a low-power LED, and the price will be much more expensive. If you buy the solar street light, but find that the brightness does not meet your own lighting requirements after installation, you can also say that this is a substandard street light. If you are purchasing in large quantities, you can order samples first. If the sample is suitable, order in bulk later. Professional solar street light manufacturer will give you the best scheme, which means provide you high performance solar street light with motion sensor with affordable price.

Look at the antistatic ability and colloid of the lamp. The LED light source with strong antistatic ability has a long service life. Generally, LEDs with anti-static voltage greater than 700V can be used in solar led street lights. The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lamps should be anti-ultraviolet and fireproof.

Understand the luminous angle of the lamps and lanterns. LED light sources with different uses have different light-emitting angles. The common light-emitting angles on the market are 8°, 15°, 25°, 45°, 60°, 90°, 120°. According to the size of the light-emitting 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 according to different needs, choose suitable lamps and lanterns.

Understand the lamp radiator. 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.

Understand the leakage current of lamps. LED is a unidirectional conductive luminous body, and a reverse current can be judged as leakage. If the leakage is serious, the life of the LED lamp will be reduced, and the price is relatively cheaper. 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.

Know the wavelength of the luminaire. The wavelength of the lamp determines the color of the light, and the quality of products produced by powerful manufacturers is generally higher. Generally, a spectrophotometer is used to produce LED lights with relatively pure colors.

The pros and cons of the solar street light source will directly affect the lighting effect of the lamps. Therefore, before purchasing solar street lights, you need to repeatedly determine the quality of the light source. The premise is to find a strong solar street lamp manufacturer, after all, the quality of outdoor lamps produced by large manufacturers is guaranteed. Shenzhen EXC-LED Technology Co., Ltd is a high tech outdoor led lighting manufacturer, established in 2009, with more than 2000 employees and 20,000 square meters, it devoted to provide global customers with high performance street lights.
