Description

The radiator structure of a kind of LED

Technical field

The utility model relates to LED technology field, and what be specifically related to is the radiator structure of a kind of LED.

Background technology

Current LED correlation technique has obtained to be applied comparatively widely, because LED light source caloric value is larger, the heat dissipation problem how solving LED light source then becomes one of main points of people's hammer away, existing radiator structure is all generally comprise the heat-conducting piece directly contacted with LED light source and several radiating fins be connected with heat-conducting piece heat transfer, this heat-conducting piece is generally comparatively thick with radiating fin connection, and it is comparatively thin with LED light source touching position, cannot rapidly by the heat conduction at LED light source place out and distribute in time, radiating effect is not good, there is the space of improving further.

In view of this, the applicant furthers investigate for above-mentioned defect, then has this case to produce.

Utility model content

Main purpose of the present utility model is the radiator structure providing a kind of LED, cannot rapidly by the heat conduction at LED light source place out and distribute in time, the problem that radiating effect is poor to solve in prior art radiator structure.

In order to reach above-mentioned purpose, solution of the present utility model is:

A radiator structure of LED, wherein, comprising: heat-conducting piece, the first groups of fins and the second groups of fins; This heat-conducting piece has the installed surface installed for LED light source, and this heat-conducting piece is solid and has thick portion and thin portion, and this installed surface is formed in thick portion, and this thick portion superordinate has the first groups of fins, and this thin portion superordinate has the second groups of fins.

Further, this thick portion and thin portion are circular cylinder, and the installed surface in this thick portion is positioned on the bottom surface of circular cylinder.

Further, this thick portion is formed with the first external screw thread in the side near installed surface, the radiator structure of this LED also comprises radiating seat, to be formed in this radiating seat for LED light source produce the optical channel that light outwards penetrates, this radiating seat is also formed with the first internal thread coordinating with the first external screw thread and be connected.

Further, this thin portion is formed with the second external screw thread in the side away from installed surface, this second groups of fins has pedestal and is formed in several fin on pedestal, and this pedestal is formed with the second internal thread, and between this second external screw thread with second internal thread, threaded engagement is connected.

Further, the radiator structure of this LED also comprises stay pipe, and this stay pipe to be set in thin portion and inconsistent with the second groups of fins.

Further, this first groups of fins and thick portion one-body molded.

After adopting said structure, the radiator structure of a kind of LED that the utility model relates to, heat-conducting piece near LED light source is set to thick portion solid by it, so higher thermal capacitance will be had, namely the heat produced by LED light source can be transferred to thick portion rapidly, a heat part is distributed by the first groups of fins be directly connected with thick portion herein, another part is then utilize the second groups of fins to distribute by thin portion, because the first groups of fins is directly connected with thick portion heat transfer, near LED light source, thermal resistance is minimum, and radiating effect is very high.

Compared with prior art, the transfer of heat that LED light source can produce by the utility model fast to place of thick portion, and passes through the setting of the first groups of fins, not only can be gone out by the heat transfer that LED light source produces fast, all right Quick diffusing, in air, extends the service life of LED light source.

Detailed description of the invention

In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.

As depicted in figs. 1 and 2, the utility model relates to the radiator structure of a kind of LED, comprising: heat-conducting piece 1, first groups of fins 2 and the second groups of fins 3; This heat-conducting piece 1 has the installed surface 11 installed for LED light source, this heat-conducting piece 1 is solid and has thick portion 12 and thin portion 13, this installed surface 11 is formed in thick portion 12, and this thick portion 12 superordinate has the first groups of fins 2, and this thin portion 13 superordinate has the second groups of fins 3.

Like this, heat-conducting piece 1 near LED light source is set to thick portion 12 solid by the utility model, so higher thermal capacitance will be had, namely the heat produced by LED light source can be transferred to thick portion 12 rapidly, a heat part is distributed by the first groups of fins 2 be directly connected with thick portion 12 herein, another part is then utilize the second groups of fins 3 to distribute by thin portion 13, because the first groups of fins 2 is directly connected with thick portion 12 heat transfer, near LED light source, thermal resistance is minimum, and radiating effect is very high.Compared with prior art, the transfer of heat that LED light source can produce by the utility model is fast to place of thick portion 12, and pass through the setting of the first groups of fins 2, not only can fast the heat transfer that LED light source produces be gone out, all right Quick diffusing, in air, extends the service life of LED light source.

Particularly, this thick portion 12 and thin portion 13 are circular cylinder, and the installed surface 11 in this thick portion 12 is positioned on the bottom surface of circular cylinder.In the present embodiment, this thick portion 12 is formed with the first external screw thread 121 in the side near installed surface 11, the radiator structure of this LED also comprises radiating seat 4, to be formed in this radiating seat 4 for LED light source produce the optical channel 41 that light outwards penetrates, this radiating seat 4 is also formed and coordinates with the first external screw thread 121 the first internal thread 42 be connected, this radiating seat 4 one aspect can play increase area of dissipation, improve the effect of radiating effect, on the other hand as a support component, may be used for supporting upper cover 6, such upper cover 6 can mounted lens 7.

As concrete a kind of connected mode, this thin portion 13 is formed with the second external screw thread 131 in the side away from installed surface 11, this second groups of fins 3 has pedestal and is formed in several fin on pedestal, this pedestal is formed with the second internal thread, and between this second external screw thread 131 with second internal thread, threaded engagement is connected.In addition, the radiator structure of this LED also comprises stay pipe 5, and this stay pipe 5 to be set in thin portion 13 and inconsistent with the second groups of fins 3.Utilize this stay pipe 5 that the second groups of fins 3 can be avoided too to be assembled to depths.

Preferably, this first groups of fins 2 is one-body molded with thick portion 12, it should be noted that, thick than traditional LED of this thick portion 12, thus plays the larger effect of thermal capacitance.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
