LED lamp beads are the English abbreviations of the light -emitting diode, which is a popular name. The light emitting diode is a commonly used light emitting device. It releases energy emitting through the composite of electronics and acupoints. It is widely used in the field of lighting. The light emitting diode can efficiently convert electrical energy into optical energy, and has extensive use in modern society, such as lighting, tablet display, medical devices, etc. How to choose the LED lamp beads of light -emitting diodes?

Light diode

     1. The brightness of the brightness LED is different and the price is different. The LED for LED lamps should meet the laser level Ⅰ standard.

     2. LEDs with strong anti -static capabilities with resistance to static capacity have long life, so the price is high. LEDs that are usually anti -static than 700V can be used for LED lighting.

     3. LED with the same wavelength wavelength, the color is consistent. If the color is required, the price is high. Manufacturers without LED spathered dust are difficult to produce pure products.

     4. Leakage current LED is a unidirectional conductivity luminous body. If there is a reverse current, it is called LED with a large leakage current with a large life span and a low price.

     5. LEDs with different use angles are different. The special lighting angle, the price is high. Such as a full corner, the price is higher.

     6. The key to different quality of life is life span, life span is determined by light failure. Light failure, long life, long life, high price.

     7. The luminous body of the chip LED is a chip. Different chips are very different. Japan and the United States have more expensive chips. Generally, Taiwan and domestic chips are lower than Japan and the United States.

     8. The size of the chip size chip is represented by the side length that the quality of large chip LEDs is better than small chips. The price is directly proportional to the size of the chip.

     9. The colloidal colloid with ordinary colloids is generally epoxy resin, and the price of LEDs with anti -ultraviolet and fireproof agent is more expensive. High -quality outdoor LED lighting should resist ultraviolet rays and fire prevention.
