Light-emitting diode lamp structure

The present invention relates to a light-emitting diode lamp structure, in particular to a substrate having a large number of through holes, so that the area of the heat conductive layer is increased to cover the entire substrate, except that the two sides of the substrate can be electrically connected to each other and more due to the heat conduction area. The structure of the light-emitting diode lamp is increased and the thermal conductivity is greatly increased.

At present, light-emitting diodes have been widely used in daily life. However, if the LED is mounted on a conventional glass fiber substrate, the thermal conductivity of the substrate made of the glass fiber is extremely poor, so that the heat generated by a large number of LEDs cannot effectively dissipate heat and burn the LED. In order to overcome this obstacle, the substrate made of aluminum instead of glass fiber came into being.

However, although the thermal conductivity of the aluminum substrate is better than that of the glass fiber substrate, the aluminum material is also thermally conductive, and in order to avoid short-circuiting between the copper circuit board and the etching, it is necessary to add an insulating layer between the copper layer and the aluminum substrate. The thickness of the insulating layer needs to be precisely controlled. If it is too thick, the heat conduction effect is not achieved; if it is too thin, the insulation effect is not good.

In addition, in the related products of the existing light-emitting diode lamps, in order to increase the illumination angle of the light source, a refractive layer is added on the lamp cover to refract some of the light sources in other directions, thereby increasing the illumination angle of the light source. However, the addition of a refractive layer to the lampshade will also greatly reduce the penetration rate of the light source to the lampshade.

As stated above, the creator of this creation contemplates and designs a light-emitting diode structure that maintains good heat dissipation and light source penetration while improving the above problems.

In view of the above-mentioned problems of the prior art, the purpose of the present invention is to provide a light-emitting diode lamp structure to solve the above problems.

According to the purpose of the present invention, a light-emitting diode lamp structure is proposed, which comprises a substrate, a heat-conducting layer, a heat-conducting column, a plurality of light-emitting units and a control module. The substrate has a large number of holes. The heat conducting layer covers both sides of the substrate and the inner edges of the plurality of holes. The heat conducting cylinder is a hollow structure to form an accommodating space, and the substrate is disposed at one end of the heat conducting cylinder. A plurality of light emitting units are distributed on both sides of the substrate. The control module is disposed in the accommodating space and electrically connected to each of the illuminating units.

The light-emitting diode luminaire structure according to the present invention may have one or more of the following advantages:

(1) The structure of the light-emitting diode lamp can be made by connecting a plurality of holes and a heat conducting layer so that the two sides of the substrate can be electrically connected to each other, thereby guiding the heat of one side to the opposite side, and then by other The heat conducting structure will heat out; in addition, the two sides of the substrate can be turned on.

(2) The structure of the light-emitting diode lamp can be arranged on both sides of the substrate by a plurality of holes of the substrate, and matched with the reflective layer of the heat-conducting column body, so that the structure of the light-emitting diode lamp has nearly 360 The omnidirectional illumination angle and the solution to the problem of increasing the illumination angle to add a refractive layer to the lampshade leads to a problem of lowering the light source transmittance.

However, the above is merely an example and is not limited by the above examples. A plurality of light emitting units 14 are distributed on both sides of the substrate 11. The control module 15 is disposed in the accommodating space 131 and electrically connected to each of the light emitting units 14 .

The material of the substrate 11 is not limited herein. However, the heat conductive layer 12 may be insulated from each other. If the manufacturing cost is further considered, the substrate 11 may preferably be a glass fiber substrate or a bakelite. limit.

As described above, after the plurality of holes 111 can cover the inner edge of the hole 111, the heat of one surface of the substrate 11 is transmitted to the other surface, and the hole 111 can facilitate the arrangement of the plurality of sides of the substrate 11. Light emitting unit 14. In more detail, it is provided on the substrate The light emitting units 14 on both sides of the ellipse can be connected to each other by the through holes 111; or a plurality of light emitting units 14 disposed on one surface of the substrate 11 with respect to the heat conducting cylinder 13 can pass through the holes 111 to the other side of the substrate 11 for connection control. Module 15. In other words, the light-emitting diode lamp structure 1 of the present invention can be covered with the holes 111 of the heat-conducting layer 12 by a plurality of inner edges, thereby increasing the heat-conducting effect of the structure 1 of the light-emitting diode lamp, and reducing the arrangement of the light-emitting units on both sides of the substrate 11. 14 difficulty.

In addition, as shown in FIG. 4 and FIG. 5, in response to the arrangement of the light-emitting units 14 being neat, a plurality of light-emitting units 14 corresponding to one side of the heat-conducting column 13 disposed on the substrate 11 may be aligned around the outer edge of the heat-conducting column 13. arrangement. The plurality of light-emitting units 14 on the other side may be arranged on the basis of the shape of the substrate 11 or the heat-conducting column 13. Thereby, the plurality of light-emitting units 14 are arranged neatly; in addition, the brightness of the light source illumination can be uniform and the angles are uniform.

Incidentally, the light-emitting diode lamp structure 1 of the present invention further includes a lamp cover 16 and a heat sink 17. The lamp cover 16 can cover the substrate 11 and the heat-conducting column 13 . Therefore, the shape of the substrate 11 and the heat-conducting column 13 should conform to the shape of the lamp cover 16 and vice versa. One end of the heat sink 17 is connected to the open end of the lamp cover 16 and the other end of the heat conducting cylinder 13 , wherein the heat sink 17 can be made of metal such as copper or aluminum.
