Description

A kind of efficient LED lamp radiator

Technical field

The utility model relates to a kind of efficient LED lamp radiator, belongs to LED lighting device technical field.

Background technology

Lightings such as existing fluorescent lamp, its power consumption is big, and needs accessories such as ballast, the production cost height, the appearance of LED lamp then is expected to thoroughly solve the existing the problems referred to above in present luminous lighting field.

LED is the abbreviation of Light Emitting Diode (light emitting diode), is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, and an end is a negative pole, and the other end connects the positive pole of power supply, makes entire wafer by epoxy encapsulation.Semiconductor wafer is made up of two parts, and a part is a P-type semiconductor, occupies an leading position in its hole, the inside, and the other end is a N-type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form a P-N knot between them.When electric current acted on this wafer by lead, electronics will be pushed to the P district, and electronics will send energy with the form of photon, the luminous principle of LED that Here it is then with hole-recombination in the P district.And the light wavelength color of light just is by the material decision that forms the P-N knot.

The Led chip is also referred to as the led luminescence chip, is the core component of led lamp, the P-N knot that just refers to.Its major function is: electric energy is converted into luminous energy, and the main material of chip is a monocrystalline silicon.Be divided into two kinds of high-power LED chip, small-power led chips according to purposes; According to color, mainly be divided into three kinds: red, green, blue (making the raw material of white light).
