How long can a solar street lamp light 30 a lamp1

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 street lamp lighting. 1. See the brightness of lamps and lanterns, generally speaking, high power leds than low power led brightness is much higher, the price will be much more expensive. 2. See the antistatic ability of lamps and lanterns light-emitting diodes, antistatic ability, long service life. Usually, antistatic is greater than 700 v power leds can be used for led lighting. 3. Understand the leakage current of lamps and lanterns light emitting diode is a kind of one-way conductive lights. If there is a reverse current, called the big leakage current leds, life is short, the price is relatively low. 4. Identify leds luminous body of light emitting diode chip is chip. Different chips usually are of good quality and price is expensive, imported from abroad. 5. See light illumination Angle different USES leds light Angle is different. According to different requirements, choose the appropriate application to buy lamps and lanterns is very important. Therefore, you should get to know you buy the application site. 6 and understand the same wavelength and wavelength of the lamps and lanterns of the same color of the light emitting diode relative prices will be higher. We should realize that no leds split testing machine manufacturers is very difficult to produce pure color products, so they must choose reputable manufacturers of products. 7. Know lamps and lanterns of colloid colloid is epoxy resin of ordinary light-emitting diodes (leds), which contain uv protection and flame retardant leds more expensive, so high quality 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 external or internal lights can be made by aluminum, solve the heating effect of the lamp, prolong the service life of the lamp. Temperature on the service life of leds beads play a key role.
