Light Emitting Diode In-line

Brightness
The brightness of the in-line LED is different, and the price is different.
Lamp cup: general brightness is 60-70 lm; bulb lamp: general brightness is 80-90 lm.
1W red light, the brightness is generally 30-40 lm; 1W green light, the brightness is generally 60-80 lm; 1W yellow light, the brightness is generally 30-50 lm; 1W blue light, the brightness is generally 20-30 lm.
Note: 1W brightness is 60-110lm; 3W brightness is up to 240lm; 5W-300W is an integrated chip, which is packaged in series/parallel. It mainly depends on how much current, voltage, how many strings and how many parallels.
LED lens: PMMA, PC, optical glass, silica gel (soft silica gel, hard silica gel) and other materials are generally used for the primary lens. The larger the angle, the higher the efficiency of light output. With a small-angle LED lens, the light must be shot farther.
wavelength
In-line LEDs with the same wavelength have the same color. If the color is required to be the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
White light is divided into warm colors (color temperature 2700-4000K), pure white (color temperature 5500-6000K), cool white (color temperature above 7000K) Europeans prefer warm white
Red light: band 600-680, of which 620 and 630 are mainly used for stage lights, and 690 is close to infrared
Blue light: Band 430-480, of which 460,465 stage lights are used more.
Green light: band 500-580, of which 525,530 stage lights are used more.
Beam angle
LEDs with different purposes have different light-emitting angles. Special lighting angle, higher price.
Antistatic ability
The in-line LED with strong antistatic ability has a long life and is therefore expensive. Generally, LEDs with anti-static voltage greater than 700V can be used for LED lighting.
Leakage current
LED is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage. The in-line LED with large leakage current has short life and low price.
