Description

Removable heat sink improved structure for LED lamps

The present invention relates to a detachable heat sink improved structure of an LED lamp, in particular, a positioning guide groove on a base body positioning structure allows the embedded portion of the heat sink to be directly inserted into and directly contacted. Providing better and direct heat dissipation, and by virtue of its stable positioning and quick assembly structure design, it can effectively reduce the assembly procedure of LED lamps.

Light-Emitting Diode (LED) lamps have the advantages of small size, power saving, high efficiency, and are not easily damaged. They are widely used in lighting and other related fields.

However, if the light-emitting diode lamp is used to increase the brightness and increase the number of light-emitting diodes, after a long time of illumination, high heat and heat radiation will be generated, which may affect the life or luminosity of the light-emitting diode. Therefore, the heat dissipation problem It is an important issue that is eager to solve.

The high heat and heat radiation generated by LED lighting mainly relies on the heat sink of the main body to exchange heat with the surrounding air to reduce the temperature. The current common LED lamps adopt non-removable heat dissipation in the heat sink portion. The sheet structure, which occupies a considerable volume for the luminaire, and the larger volume is not conducive to loading and distribution, resulting in a problem of cost increase.

Although the manufacturer has developed a detachable heat sink structure, as shown in FIG. 5, the conventional embedded portion 201 of the conventional heat sink 20 can be inserted into the positioning structure of the base body, but it needs to be inserted after the insertion. The adhesive is applied to make it firmly positioned. Although these problems can be overcome, the assembly is complicated, the labor and cost are increased, and the heat sink 20 is The base body is separated by an adhesive, and the heat conduction is not directly contacted, and the heat dissipation effect is relatively discounted. Therefore, the structure still has many shortcomings to be overcome.

In order to solve the above technical problem, the purpose of the present invention is to provide a detachable heat sink improved structure of an LED lamp, wherein the positioning guide groove on the base body positioning structure can directly insert the embedded portion of the heat sink into the heat sink. Direct contact, providing better and direct heat dissipation, and through its stable positioning and quick assembly structure design, can effectively reduce the assembly process of LED lamps.

The technical means and efficacy of the present invention for achieving the purpose will be described below with reference to the accompanying drawings, and the embodiments listed in the following figures are merely supplementary explanations, so that the reviewing committee members can understand, but the technical means of the present case are not Limited to the listed figures.

Referring to FIG. 1 , the detachable heat sink improved structure of the LED lamp of the present invention includes at least a base body 1 and a heat sink 2 .

The base body 1 has a short cylindrical shape, and a positioning structure 11 is disposed on an outer circumference of the base body 1. The positioning structure 11 is provided with a positioning guide 111 extending through the positioning groove structure.

Referring to FIG. 2, the heat sink 2 is in the form of a flap. The one side is provided with an embedding portion 21, and the embedding portion 21 is formed by press forming, and has a wave-bending structure, and the wave-shaped portion of the embedding portion 21 The width of the folded structure is slightly larger than the groove of the positioning guide 111 of the base body 1. width.

Referring to FIG. 3 and FIG. 4, the detachable heat sink improved structure of the LED lamp of the present invention, the positioning guide 111 provided on the base body 1 can directly embed the embedded portion 21 of the heat sink 2 Inserted into the positioning guide 111, the heat sink 2 is inserted into the positioning guide 111, because the width of the wave-shaped structure of the embedded portion 21 is slightly larger than the width of the positioning guide 111 of the base body 1. The metal elasticity of the bent portion of the embedded portion 21 of the heat sink 2 is such that the embedded portion 21 is firmly positioned in the positioning guide 111, and the heat sink 2 is firmly and firmly coupled to the base body 1 . Achieve the expected positioning needs.

According to the combination of the above components, the detachable heat sink improved structure of the LED lamp provided by the present invention can directly embed the embedded portion 21 of the heat sink 2 by the positioning guide 111 on the positioning structure 11 of the base body 1 The structural design inserted into it provides the effect of stable positioning and quick assembly, and can effectively reduce the assembly procedure of LED lamps.

In addition, due to the improved structure of the detachable heat sink of the LED lamp provided by the present invention, the positioning guide 111 on the positioning structure 11 of the base body 1 can directly insert the embedded portion 21 of the heat sink 2 into the housing. The structural design therein does not require the conventional embedding portion 201 of the conventional heat sink 20, as shown in FIG. 5, after the insertion, it needs to be coated with an adhesive to make it firmly positioned. Therefore, the creation has no complicated assembly, the labor and cost are increased, and the heat sink 2 is directly inserted into the base body 1. The metal of the two is in direct contact, so that direct and rapid heat conduction can be provided, thereby obtaining Good heat dissipation.

Furthermore, the detachable heat sink of the LED lamp provided by the present invention has an improved structure, and the shape and shape of the heat sink 2 can be changed according to different needs of the use, such as modeling or function. In order to make LED lamps more flexible and widely used.

However, the above-mentioned ones are only examples of the present creation, and it is not possible to limit the scope of the implementation of this creation; therefore, the simple equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification should be It is still covered by this creation patent.
