High-power LED lamp beads Knowledge summary

Compared with low-power LED lamp beads, high-power LED lamp beads have higher power and brighter brightness. The rated current of low-power LED lamp beads is usually 20mA, and the rated current higher than 20mA can basically be regarded as high-power LED lamp. Beads.
The unit of low-power brightness is generally mcd (millicandela, 1cd=1000mcd), which is the luminous intensity; the common power files of high-power LED lamp beads are: 0.2W, 0.5W, 1W, 3W, 5W, 10W, etc., the brightness unit It is LM (lumens).
High-power LED lamp beads are mainly imitation lumen lamp beads
Analysis of the advantages of high-power LED lamp beads
1. Less power consumption: The power consumption of high-power LEDs with a light efficiency of 120LM/W is greatly reduced compared to incandescent lamps with the same brightness;
2. Long lifespan: The lifespan of high-power LED lamp beads is as long as 50,000 hours, and it can be used for more than 5 years when it is continuously lit for 24 hours;
3. Fast response speed: nanosecond response speed of high-power lamp beads makes dynamic control of brightness and color simple: dynamic color change and digital control can be realized;
4. Large design space: it can be integrated with the building to achieve the effect of seeing only the light but not the light.
5. Environmental protection: LED lamp beads have no harmful metal mercury, no infrared and ultraviolet radiation;
6. Color: Different wavelengths produce different colors of light, bright and saturated, no filter is needed, and can be controlled by the three primary colors of red, green and blue to form a variety of different colors, which can achieve various color changes such as full-color gradation.
In the application process of high-power LED products and devices, factors such as welding, electrostatic protection, and heat dissipation have a great impact on their characteristics, and they need to be highly valued by application-side customers. We produce quality 3528 Smd Led Diode.
