Description

LED light dissipation structure

This creation is a kind of LED lamp heat dissipation structure, which makes the heat dissipation structure of the LED lamp increase the endurance strength and enhance the heat dissipation efficiency.

Check, the conventional LED lamp heat sink structure, generally shown in Figure 4, is a heat sink 1 surface is provided with a plurality of heat sink 2, each heat sink 2 has a gap H, which is by the heat sink 2, the gap H Dissipate air to dissipate heat. The above structure actually has the following disadvantages: (1) The gap H shown in Fig. 4 is elongated, so that the air can only flow laterally and cannot flow vertically, and the circulation of air is restricted by direction, and cannot be circulated in all directions. The heat dissipation efficiency is poor. (2) The surface area of the chip heat sink is smaller than the cylindrical shape, so the heat dissipation efficiency is also poor. (3) The chip heat sink is not suitable for the fixture of the assembled transformer.

This creation is to improve the above-mentioned shortcomings. The main techniques and purposes are as follows: (1) A plurality of heat-dissipating rods are arranged on the heat-dissipating body to form a gap around each of the heat-dissipating rods, and the air circulation is smooth, and the heat dissipation effect is good. Moreover, the rod-shaped heat dissipating rod can increase the heat dissipating area. (2) The reinforcing ring with the through hole is sleeved on the heat dissipating rod, and is stable and can bear a large weight, so that the reinforcing ring can be used for assembling the fixing frame of the transformer.

Referring to FIG. 1 , 2 and 3 , a heat sink 10 is assembled on one side of the lamp cover 15 , and the other side is provided with a plurality of heat dissipation rods 11 spaced apart from each other. Each of the heat dissipation rods 11 has a gap H around it, and a reinforcing ring 12 is formed. With multiple holes a through-hole 13 of the distribution, each of the through-holes 13 can fit the heat-dissipating rod 11 of the heat-dissipating body 10, and cooperate with a plurality of fixing columns 14 and the heat-dissipating body 10, and the reinforcing ring 12 is used for assembling the fixing frame 16 of the transformer 17; In addition, the heat dissipation rod 11 of the heat sink 10 may be integrally formed by forging.

The above structure can form the following functions and advantages:

(1) As shown in FIG. 3, the heat dissipating rod 11 of the heat dissipating body 10 has a gap H around it, which allows the air to circulate in any direction, and has an excellent heat dissipation effect.

(2) Each of the heat dissipating rods 11 has a cylindrical shape, and has an increased area than the sheet fins, and the heat dissipating area is increased.

(3) As shown in FIG. 2, the reinforcing ring 12 has a plurality of through holes 13 of the plurality of holes, and each of the through holes 13 can fit the heat dissipating rod 11 to form an extremely stable and obtainable effect of increasing the endurance strength, because the fixing bracket 16 can be assembled. Have a solid effect.

In summary, the structure of this creation does have excellent practicality and enhanced efficiency, and it is in line with the new patent principle, so please grant a patent.
