The Principle Of Practical Led Point Light

The Principle Of Practical Led Point Light

Led light useful led point light is now more people use a kind of, we all know that this kind of light it has many unique advantages, just by people like, so before choosing must understand the principle of led light practical led point light is what. Led light emitting principle: The PN junction inside the led, under the action of voltage drive, the internal electrons and holes will compound, the compound process energy will be released in the form of light, this is the working principle of led light.

1, Led light emitting principle is the use of light-emitting diodes, and now there are a variety of led lights and various colors of good led point light led lights, practical led point light led lights are a very energy saving bulb. Led lights made of different materials can emit different colors, such as red, blue and so on.

2, The core part of the led is composed of p-type semiconductor and n-type semiconductor chip, between the p-type semiconductor and n-type semiconductor has a transition layer, called p-n junction, usually using double heterojunction and quantum well structure.

The principle of the led lamp practical led point light is that after being connected to a power source, the current passes through the p-region of the semiconductor, where it recombines with electrons and holes, and is finally presented as light. Good led point light led lights are semiconducting materials that are typically cured to a scaffold using silver glue and sealed with epoxy resin to protect the wires.
