Background technique

LED light-emitting diode is a solid-state semiconductor device that can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a P-N junction. When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is with hole recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is. And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction.

The existing LED bracket structure mainly includes two brackets, two conductive feet, a semiconductor chip, conductive wires and a silicone lampshade. Since the two brackets and the two conductive feet are integrated, the two brackets and the two conductive feet must be made of red copper or brass with relatively good conductivity, so the structure cost of the traditional LED bracket is relatively high.

Contents of the invention

In order to solve the above-mentioned technical problems, the utility model adopts the following scheme:

An LED bracket structure, comprising two brackets, two conductive feet, a semiconductor chip, a conductive wire and a silicone lampshade, the two brackets are connected to the two conductive feet, and the semiconductor chip is connected to the conductive wire through the conductive wire. The two brackets are connected, and a rectangular fixing groove is respectively provided under the two brackets, and the two conductive pins are inserted into the fixing grooves.

Further, a current limiting resistor is connected in series on the conductive line.

Compared with the traditional LED bracket structure, the LED bracket structure has the following beneficial effects:

(1) Since the two brackets and the two conductive feet of the utility model can be separated, lower-priced conductive metals can be used for the two brackets, which can greatly reduce the amount of precious metal copper used in traditional brackets and save manufacturing costs.

(2) The utility model is provided with the described current-limiting resistance that plays current-limiting effect in series in the inside of light-emitting diode, and described current-limiting resistance reduces the emission of PN junction heat, guarantees the luminous intensity of light-emitting diode.
