Solar street lamps light source q&a ( 6) Buy led chip street lamp control should note

A: with the led chip technology matures and progress, is engaged in the research and development of led chip manufacturers are also more and more, the quality of the led chip is becoming more and more manifests the different development direction, quality is good and bad are intermingled, price difference is bigger. How to choose the suitable LED,

a: with the LED chip technology matures and progress, more and more manufacturers begin to be engaged in research and development of LED chip. The quality of the led chip is more and more reflect the developing direction of differentiation. Quality, price difference is bigger. How to choose the suitable light emitting diode, solar street light products to meet the needs of users, generally need to know first of all, the following several aspects have chip maker. At present, widely used in the domestic market of led chip maker including CREE, the PRE, jingyuan, HongGuang, TaiGu, geely, etc. The country and the largest SANA chips. Each manufacturer has its own characteristics and quality, the buyer need according to their own conditions are put forward. The second is the choice of chip specifications. Common chip size is usually 45 mil, 40 mil, 38 24 mil mil, 30 mil, and other specifications. For the same manufacturer of the chip, chip size is more expensive than the chip size ( Note: 1 mil = 0. 001 '= 25. 4 um, then select encapsulation parameters to determine the led bracket and lens material. Light emitting diode bracket typically made into copper ( At present there are iron material, aluminum material and pottery and porcelain, etc. ) , some of the lenses are made of PC materials, some of them are made of silicone. It should be noted that polycarbonate lens can't return, only need to manual welding. Led lighting parameters, mainly including flux, color temperature, color rendering index, illumination Angle and other parameters, will launch. Finally, to pay attention to the quality of the led consistency: mainly refers to the color of the led, brightness, voltage drop, and classify different perspective of multifunctional light pole packaging. The higher the working characteristic of consistency, the higher the price, and quality control ability is poor, the production process of unstable similar light-emitting diode suppliers 'hybrid packaging' of the light-emitting diode chip, the lower the price.
