Where is the street light
Popularization of solar LED street light, the more and more widely applied, the LED light source quality directly affects the use effect. How to determine the pros and cons of solar LED street light? 1, see the brightness of lamps and lanterns are generally large power LED brightness is smaller than the power of the light will be many
solar LED street lamp is becoming more and more popular and widely used. The quality of the led light source directly affect the use effect. How to judge the advantages and disadvantages of solar led streetlight? 1, see the brightness of lamps and lanterns in general, the brightness of the power leds is brighter than low power leds, and the price is much higher. 2, observe the antistatic ability of lamps and lanterns antistatic ability of light-emitting diodes, long service life. Usually, only the antistatic ability is greater than 700 v leds can be used for led lighting. 3, understand the leakage current of lamps and lanterns light emitting diode is a one-way conductive lights. If there is reverse current, it is called leakage. Leakage current big led life is short, the price is relatively low. 4. Used to identify leds luminous body of light emitting diode chip is a chip. Different chips usually are of good quality, the price is expensive. All chips are imported from abroad. 5, look at the lighting Angle different USES of lamps and lanterns of leds have different light Angle. According to different requirements, choose the appropriate application to buy lamps and lanterns is very important. Therefore, it is necessary to understand their purchase application site. 6 and understand the same wavelength and wavelength of the lamps and lanterns of the same color of the light emitting diode prices are relatively high. We should be aware of not light-emitting diode testing instrument manufacturers is very difficult to produce a color pure product, so there must be products of reputable manufacturers. 7, understand the colloid ordinary light-emitting diodes (leds) colloid of lamps and lanterns is epoxy resin, and light-emitting diodes (leds) with uv protection and flame retardants are more expensive. The quality of the outdoor led lighting should be uv protection and fire prevention. 8, understand the lamps and lanterns of radiator radiator can see the appearance of the lamp. If the lamp of external or internal by aluminum, can solve the heating effect of the lamp, to better extend the service life of the lamp. Temperature on the service life of led lamp bead plays a key role.
