Description

LED bulb heat radiation structure

Technical Field

The utility model relates to the technical field of LED bulbs, in particular to a heat dissipation structure of an LED bulb.

Background

The LED lamp is a lamp using a light emitting diode as a light source, generally uses silver colloid or white colloid to solidify a semiconductor LED on a bracket, then uses silver wires or gold wires to connect a chip and a circuit board, uses epoxy resin to seal the periphery to protect an internal core wire, and finally installs a shell, thereby having the advantages of energy saving, long service life, environmental protection, shock resistance and the like, being capable of directly emitting seven colors of light and being generally applied to the fields of traffic signals, display screens, automobile signals and the like.

In the led lamp of the present stage, consider that the luminous of lamp is even, specially designed 360 degrees are luminous, and its shape is like the corn-on-cob, specially called the maize lamp, and this kind of maize lamp is comparatively concentrated because the lamp pearl when using, and the heat generation is fast, and the maize lamp of the present stage only dispels the heat through inside aluminium core and the radiating part that communicates with the aluminium core, and radiating part area is less, is unfavorable for in time radiating with the air contact surface, and the inefficiency.

Disclosure of Invention

To the not enough of above-mentioned prior art, the technical problem that this patent application will solve is how to provide a simple structure, and radiating efficiency is high, convenient to use's LED bulb heat radiation structure.

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

the utility model provides a LED bulb heat radiation structure, includes the lamp holder, install the drive in the lamp holder, lamp holder and support frame fixed connection, the support frame passes through aluminum product integrated into one piece, LED paster formula lamp pearl is installed to the outside and the lower extreme of support frame, the support frame axial runs through and is provided with the wire hole, the upper end of support frame distributes and installs the radiator unit that a plurality of intervals set up, radiator unit includes a plurality of fixed mounting radiating fin on the support frame, radiating fin interval sets up, be provided with the heat dissipation chamber between radiating fin and the support frame, the distribution is provided with the louvre on the support frame, the louvre sets up between two adjacent sets of radiator unit.

Like this, the support frame passes through aluminum product integrated into one piece, and LED paster formula lamp pearl produces heat in the use, and the heat transfer gives the aluminum product, dispels the heat through the aluminum product. Through the setting of radiating fin, increased the area of contact of aluminum product and air, improved radiating efficiency. The radiating fin is provided with the radiating cavity between the support frame, further increases the area of contact with air, is provided with the louvre simultaneously, can both improve radiating efficiency.

Wherein, radiating fin is made through aluminum sheet bending.

Wherein, the outer end of radiating fin is provided with the circular arc.

Wherein, radiating fin welds with the support frame.

Wherein, the pore wall distribution of louvre is provided with a plurality of heat dissipation bulge loops.

In conclusion, the utility model has the advantages of simple structure, high heat dissipation efficiency and convenient use.
