LED Lamp Bead Parameter Description

1. The brightness of the brightness LED lamp beads is different and the price is different. Lantern cup: Generally brightness is 60-70LM; Bubble Lights: Generally brightness is 80-90LM. 1W red light, brightness is generally 30-40lm; 1W green light, brightness is generally 60-80lm; 1W yellow light, brightness is generally 30-50lm; 1W blue light, brightness is generally 20-30lm. Note: 1W brightness is 60-110LM; 3W brightness can reach up to 240lm; 5W-300W is an integrated chip, which is packed in string/parallel. LED lens: PMMA, PC, optical glass, silicone (soft silicone, hard silicone) and other materials are generally used in lens. The larger the angle, the higher the light efficiency. With a small angle LED lens, the light must be shot far. 2. The wavelength wavelength is consistent, the color is consistent. The price is high. White light is divided into warm color (color temperature 2700-4000K), white (color temperature 5500-6000K), cold white (color temperature above 7000K) Europeans prefer warm white. Hongguang: The band 600-680, of which 620, 630 are mainly used for stage lights, 690 is close to infrared rays. Blu-ray: band 430-480, of which 460,465 stage lights are used more. Green light: 500-580 bands, of which 525,530 stage lights are used more. 3. LEDs with different use of light emitting angle are different. Special lighting angle, high price. 4. LED lamp beads with strong anti -static capabilities with resistance to static capacity, long life, so the price is high. LED lamp beads that are usually more than 700V with antistatic can be used for LED lighting. 5. Leakage current LED lamp bead is a unidirectional conductivity luminous body. If there is a reverse current, it is called leakage, LED lamp beads with large leakage current, short life, low price, low price. LED lamp beads are widely used for lighting lighting, LED large screen display, traffic lights, decoration, computers, electronic toy gifts, switches, telephones, advertising, urban glittering engineering and many other production areas.
