High power LED solar lights and LED point light source selection skills

High power LED lights and LED point light source selection approach should be to analyze from the nine aspects: 1, LED brightness LED brightness is different, the price would be different. Light cup: general brightness for the 60 - 70lm; Ball steep light: general brightness is 80 - 90 lm。 Note: 1 w brightness for 60 - Lm5w - 110 lm3w brightness of up to 240 300 w is integrated chip, using series/parallel encapsulation, basically see how much current, voltage, and a few strings. 1 w red light brightness for 30 - commonly 40lm; Brightness is generally 60-1 w green 80 lm; 1 w yellow brightness for 30 - commonly 50lm; 1 w blue light brightness for 20 - commonly 30lm; LED lens: a lens PMMA, PC, is commonly used in optical glass, silica gel ( Soft silicone, hard silicone) Such as material. Angle of the light efficiency is higher, the greater the LED lens with a small Angle, the light will shoot far. 2 antistatic ability of leds, antistatic ability, long service life, thus higher prices. Antistatic usually greater than 700 v LED can be used in the LED lighting. 3, consistent LED wavelength wavelength, color is consistent, such as request the same color, the price is high. Not the manufacturer of the LED light color separation instrument is not easy to produce pure color products. The white light warm color ( Color temperature 2700 - 4000 k) Is white ( Color temperature 5500 - 6000 k) Cold, white ( Color temperature above 7000 k) Europeans prefer warm Bai Hongguang: band - 600 680, 620630 of which is mainly used for stage lights, 690 near infrared blu-ray: band - 430 480, of which 460465 stage light with more. Green: band - 500 580, of which 525530 stage light with more. 4, the leakage current of LED is a one-way conductive lights, if there is a reverse current, is called the leakage, leakage current big LED, short service life, low price. 5, light Angle USES different LED light Angle is different. Special light Angle, the price is higher. 6, different life quality is the key to life, life is decided by droop. Droop small, long service life, long life, high price. 7, the LED chip LED lights for chip, different chip, price difference is very big. Japan, the United States of the chip is more expensive, factory with local manufacturers of the LED chip price is lower than the day, the United States. 8 chip, chip size to the size of the side, said the chip size is commonly: 38 - 45 m Ω, large LED chip quality is better than that of the small chip. The price is proportional with the chip size. 9, colloid 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.
