How to determine the manufacturer of solar road solar street lamps light source of the mass

The popularization of solar street light, LED lamps and lanterns is becoming more and more widely used, the LED light quality directly affects the use effect. You are below a brief introduction of how to judge the merits of the solar street lamps light source. See the brightness of lamps and lanterns: are generally work



the popularization of solar street light, LED lamps and lanterns is becoming more and more widely used, the LED light quality directly affects the use effect. You are below a brief introduction of how to judge the merits of the solar street lamps light source. See the brightness of lamps and lanterns: are generally large power LED brightness will be smaller than the power of light a lot, at the same time the price will be expensive. See the antistatic ability of lamps and lanterns: antistatic ability of LED, long service life. Antistatic usually greater than 700 v LED can be used in the LED lighting. Understand the leakage current of lamps and lanterns, LED is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED, life is short, prices are relatively low. Identification chip LED lamps and lanterns: LED lights for chip, different chip, generally good quality price expensive chips were imported. See the light Angle of lamps and lanterns: use different LED light Angle is different. According to different needs, choose to suit oneself buy the applications of lamps and lanterns is very important. So to buy their own application field have to understand. Know the wavelength of lamps and lanterns: wavelength consistent leds, color is consistent, relative prices will be higher. We should be aware of, not the manufacturer of the LED light color separation instrument is not easy to produce the pure color products, so there must be a choice products of reputable manufacturers. Chip size: the size of the chip to side, said big LED chip quality is better than that of the small chip. The price is proportional with the chip size. Understand the colloid of lamps and lanterns: ordinary LED colloid generally for epoxy resin, leds with uv radiation and fire retardant added more expensive, high quality outdoor LED lighting should be uv and fire prevention. Understand the power of lamps and lanterns: according to the design requirements of different manufacturers, can be divided into constant current power supply and constant voltage power supply two kinds, no matter which kind of, the power of the whole service life of the lamp only plays a central role. If the lamps will be broken, are generally the power supply is burnt out. Know lamps and lanterns of radiator, radiator can see the appearance of lamps and lanterns, if the external or internal of lamps and lanterns is made of aluminum, could solve the thermal effect of lamps and lanterns so as to achieve better prolongs the service life of lamps and lanterns, temperature on the service life of LED lamp bead plays a critical role.
