How to distinguish between light bead and wick?

Lamp bead is composed of LED chip, bracket, lens, shell, wire, etc., the lamp bead is the most critical is its luminous effect, as well as the stability of the luminous performance, and the luminous the biggest factor of the determinants of the decision by the LED chip, which is the lamp bead internal light-emitting components.

Chip is for the lamp bead composition process, in the lamp bead manufacturing process, the package coveted bracket, chip lens lamp and other components, and the LED chip is the most important part.

The difference between beads and chips:Beads are mainly responsible for emitting light, while the chip is to control the parameters and performance of the LED, the specific differences are as follows:

Different functions
The lamp bead is mainly to produce light, the quality of its good or bad will directly affect the brightness, color, uniformity and other effects of LED lighting; and the chip is the control center of the LED bulb, can control the parameters and performance of the LED, for the stability of the lamps and lanterns, color temperature, brightness adjustment, etc. has an important role

Different structure
Bead refers to the surface part of the LED wafer, usually using gold wire or carbon rod to connect the electrode, so as to realize the LED power supply and light-emitting direct connection; while the chip refers to the LED lighting control circuit, usually composed of multi-layer circuit boards and microelectronic devices, is to control the work of the LED bulb key components.
