new energy solar street light has now become the indispensable energy in your life. At the same time, the LED lamp is more and more widely accepted by people. LED light source directly influences the quality of daily use effect. How to distinguish between solar street lamps light source with the quality of lamps and lanterns? First of all, to see the brightness of the light. In general, the brightness of the power leds than small power led brightness is much higher, and the price is much higher. 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. At present, the light-emitting diodes (leds) on the market is basically 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. Different USES leds light Angle is also different. 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. The same wavelength and the higher price the same color of the light emitting diode. The chip size: the size of the chip with side length. Big chip light-emitting diodes (leds) quality is better than small chip. The price is proportional to the chip size. Ordinary light emitting diode colloid is commonly 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. According to the design requirements of different manufacturers, can be divided into two types: constant current power supply and constant voltage power supply. Whatever the type, the power supply in the whole service life of the lamps and lanterns are plays a central role. If the light is broken, the power will often burn out. The other is a through the radiator to observe 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.
