Technical choices high-power LED lights and LED light source
GCL is a leading manufacturer and exporter of LED lighting,Our main products line including: led lights,led bulbs,led light,led strip lights,led tube.
High power LED lamp beads and selection of LED point light source should be from the following nine aspects to analyze:
A, LED brightness
LED brightness is different, the price will be different.
Cup: the general brightness to 60-70lm;
Bulb: general brightness to 80-90lm.
Note: the 1W brightness 60-110lm3W brightness can reach 240lm5W-300W is integrated chip, using serial / parallel package, mainly to see how much current,voltage, and few on.
1W red light brightness is generally 30-40lm; 1W green light brightness is generally 60-80lm; 1W yellow brightness is generally 30-50lm;
1W Blu ray brightness is generally 20-30lm;
LED lens: a lens with the general PMMA, PC, optical glass, silica gel (silica gel, soft,hard materials such as silica gel). The larger the angle the light efficiency is high, with a LED lens small angle, the light will shoot far.
Two, antistatic ability
Antistatic ability of the LED, long life, and high prices. Antistatic usually greater than 700V LED can be used for LED lighting.
Three, the wavelength
Wavelength consistent LED, consistent color, such as color, high prices. No LEDspectrophotometric color instrument manufacturer is very difficult to produce pure color products.
White light consists of warm color (color 2700-4000K), white (color 5500-6000K), cool white (color temperature above 7000K) Europeans like warm white
Red: the band 600-680, of which 620630 for the main stage lights, 690 near infrared
Blue: the band 430-480, of which 460465 stage lamp with the more.
Green: the band 500-580, of which 525530 stage lamp with the more.
Four, the leakage current
LED is a one-way conductive light-emitting body, if the reverse current, called theleakage, the leakage current of ~ LED, short service life, low price.
Five, light-emitting angle
Use different LED the light angle is not the same. Light-emitting angle is special, the higher price.
Six, life
Different quality is the key of life, ~ ~ life is decided by the light fades. Light a small decline, long life, long life, high price.
Seven, the LED chip
Illuminant of ~~LED chip, the chip is different, the price difference is very great.Japan, the United States of America, more expensive chips, Taiwan factory with Chinese manufacturers LED chip prices lower than in Japan, u..
Eight, the chip size
The size of the chip to side said, chip size is generally: 35-45mil, ~ LED chip qualityare better than small chip. The price is directly proportional to the size of the samechip.
Nine, colloid
~ ~ the ordinary LED colloidal general epoxy resin, plus with UV and fire retardantLED is more expensive, high-quality outdoor LED
