Do you know the LED0603 lamp bead parameters? Today Xiaobian will take you to understand the 0603LED lamp beads from two aspects.

First, the brightness

Lamp cup: general brightness is 60-70lm; bulb: general brightness is 80-90lm.

1W red light, the brightness is generally 30-40lm; 1W green light, the brightness is generally 60-80lm; 1W yellow light, the brightness is generally 30-50lm; 1W blue light, the brightness is generally 20-30lm.

Note: 1W brightness is 60-110lm; 3W brightness is up to 240lm; 5W-300W is integrated chip, with serial/parallel package, mainly see how much current, voltage, several strings and several.

LED lens: The primary lens is generally made of PMMA, PC, optical glass, silica gel (soft silica gel, hard silica gel). The larger the angle, the higher the light efficiency, with a small angle LED lens, light

I have to shoot far.

Second, the wavelength

The wavelength is the same and the color is the same, the price is high.

White light warm color (color temperature 2700-4000K), white (color temperature 5500-6000K), cool white (color temperature 7000K or more) Europeans prefer warm white.

Red light: Band 600-680, of which 620, 630 is mainly used for stage lights, and 690 is close to infrared.

Blu-ray: 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.
