Lighting module

Abstract

A luminous module comprises a luminous unit having a leading leg, cooling plates closely sticked on the luminous unit and insulating plates assembled under the cooling plates. The cooling plates have perforated slots corresponding to the leading leg. The insulating plates have a preset conductive pattern and perforations corresponding to the perforated slots. The leading leg of luminous unit and the perforations of the insulating plates are electrically connected on the preset conductive pattern through the perforated slots of cooling plates.

Description

technical field [0001] The invention relates to a light emitting module, especially a light emitting module combined with a heat dissipation mechanism that can be easily assembled. Background technique [0002] Light, thin and small is one of the common trends of today's products. The solution usually starts from the component structure or space design; as shown in Figure 1, a fixed structure applied to the heat dissipation of the existing flashlight 1a, the flashlight 1a has a capacitor inside. There is a space 11a for placing an electric storage device 12a, and the flashlight 1a has conductive mechanisms 13a and 14a electrically connected to the electric storage device 12a at the end, wherein the conductive mechanism 13a is electrically connected to the light emitting unit 15a, so that The power storage device 12a and the light-emitting unit 15a are connected to each other so that the flashlight 1a has a light-emitting function. Since the light-emitting unit 15a may have ...

Problems solved by technology

However, as mentioned above, to assemble the flashlight 1a, the aluminum ring 21a needs to be used to fix the conductive mechanism 13a inside it, and then the aluminum sleeve 2a for heat dissipation is inserted, and then the other parts of the flashlight 1a are assembled sequentially, and the assembly steps are redundant. ; In addition, the conductive mechanism 13a is made of a polypropylene plate 132a (commonly known as PP plate) and two metal plates 131a, 133a, and the light emitting unit 15a is arranged on one of the metal plates 133a for direct contact, and The metal plate 133a is used to fold downwards on its periphery to cover another metal plate 131a, so that the light-emitting unit 15a uses the metal plate 133a to conduct heat outward, but the two metal plates 131a, 133a are only in contact with each other. It is limited to the contact area of ​​the surrounding concave folds or the heat is transferred out through the screw lock element 134a, and then the metal plate 133a is used to directly contact the aluminum ring 21a for locking to dissipate heat, but the actual heat conduction contact area between the aluminum ring 21a and the metal plate 133a It is ring-shaped, and the heat dissipation area is increased through the aluminum sleeve 2a for heat dissipation. Not only is the heat dissipation efficiency low, but also the assembly method between the metal plate 133a and the aluminum ring 21a and the aluminum sleeve must be considered in this structure. 2a The conduction effect of contact, in addition, when the heat is conducted between the two metal plates 131a and 133a, and between the aluminum ring 21a and the metal plate 133a in a ring shape, there are actually many bottlenecks that cannot be transferred quickly , which affects the heat dissipation efficiency, and shows that this structure has its obvious lack
