Description

A kind of LED lamp

Technical field

The utility model relates to light sources technical field more particularly to a kind of LED lamp beads.

Background technique

LED is a kind of semiconductor electronic component that can convert electrical energy into luminous energy, and LED lamp bead is small in size, light-weight, is used Service life is long, and energy conservation and environmental protection, application is more and more extensive, but at this stage, and the power of single led wick is lower and calorific value is big, such as Less than timely radiating, it will influence the optical power and service life of LED lamp.

Utility model content

In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of LED lamp, which has Optical power is big, the good feature of thermal diffusivity.

The utility model solves technical solution used by its technical problem are as follows:

A kind of LED lamp, including matrix and it is set to the intracorporal copper stent of base, it is successively arranged core from bottom to top on copper stent Piece and phosphor powder layer, the chip are connected with electrode pad, and chip is coated with thermal grease layer, the copper stent lower end on surface Equipped with the radiating part for extending to matrix surface, photic zone is equipped with above the phosphor powder layer.

As an improvement of the above technical solution, the electrode pad includes positive terminal pad and negative terminal pad, positive terminal pad and Negative terminal pad connects two pin feet on chip by gold thread.

As an improvement of the above technical solution, the positive terminal pad and negative terminal pad outer surface are silver-plated.

As an improvement of the above technical solution, described matrix is cube, and one of angle is equipped with notch.

As an improvement of the above technical solution, the radiating part is set to matrix lower surface center.

The beneficial effects of the utility model have:

This LED lamp is set on the intracorporal copper stent of base and is successively arranged chip and phosphor powder layer from bottom to top, and chip connects It is connected to electrode pad, chip surface is coated with thermal grease layer, and copper stent lower end is equipped with the radiating part for stretching out matrix surface, chip And the heat that phosphor powder layer generates is realized rapid cooling, is effectively reduced by the transmitting of thermal grease layer, copper stent and radiating part Optical attenuation improves the service life of wick.

Detailed description of the invention

With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, in which:

Fig. 1 is the structural schematic diagram of the utility model embodiment；

Fig. 2 is the top view of the utility model embodiment；

Fig. 3 is the bottom view of the utility model embodiment.

Specific embodiment

Referring to Fig. 1, a kind of LED lamp of the utility model, including matrix 1 and the copper stent 2 being set in matrix 1, copper Chip 3 and phosphor powder layer 4 are successively arranged on bracket 2 from bottom to top, the chip 3 is connected with electrode pad, and chip 3 applies on surface It is covered with thermal grease layer 5,2 lower end of copper stent is equipped with the radiating part 6 for extending to 1 surface of matrix, sets above the phosphor powder layer 4 There is photic zone 7.

Thermal grease layer 5 has excellent thermal conductivity, and chip 3 generates heat when being powered, and heat is quickly successively through thermal grease layer 5, copper stent 2 and radiating part 6 are transmitted to outside LED lamp, avoid the LED lamp optical attenuation generated by fever, improve LED light The service life of core.

Wherein, the electrode pad includes positive terminal pad 8 and negative terminal pad 9, and positive terminal pad 8 and negative terminal pad 9 are led to respectively Cross two pin feet on the connection chip 3 of gold thread 10.The positive terminal pad 8 and 9 outer surface of negative terminal pad are silver-plated, help to improve Electrode pad inoxidizability improves heat dissipation and electric conductivity, and LED lamp can be welded on lamp cap substrate by electrode pad, group At different capacity or the LED lamp holder of different shapes.

Referring to fig. 2, described matrix 1 is cube, and one of angle is equipped with notch 11, and personnel is facilitated to confirm installation direction.

With further reference to Fig. 3, the radiating part 6 is set to 1 lower surface center of matrix, and positive terminal pad 8 and negative terminal pad 9 are set to The two sides of radiating part 6.

The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality Example is applied, as long as its technical effect for reaching the utility model with any same or similar means, all should belong to the utility model Protection scope.
