Embodiment Construction

[0057] The invention discloses a light-emitting module with heat dissipation function and its assembly method, please refer to figure 1 as shown, figure 1 It is a schematic diagram of the light-emitting module of the present invention. Conceptually, the light emitting module 1 of the present invention at least includes a light emitting diode unit 3 , a heat sink 2 and a circuit board 6 . The LED unit 3 is located on the circuit board 6 and electrically connected to the circuit board 6 , and the LED unit 3 protrudes from at least one thermally conductive folded foot 332 . The heat sink 2 is provided with at least one opening 21 (such as the second opening 217 in FIG. 2A ). The light-emitting diode unit 3 extends the heat-conducting folded foot 332 out of the breach 21, so that the light-emitting diode unit 3 can contact the first surface 201 of the heat sink 2, and at the same time, one end of the heat-conducting folded foot 332 protruding out of the breach 21 can be bent Th...

Abstract

The invention discloses a light emitting module with the radiating function, an emitting cover thereof and an assembly method thereof. The light emitting module comprises a circuit board, a radiating fin, a light emitting diode unit and at least a heat conducting folded foot. A breach is arranged on the radiating fin; the light emitting diode unit is positioned on the circuit board and is in contact with the first surface of the radiating fin; and the heat conducting folded foot is positioned on the light emitting diode unit, extends out of the breach, and is in contact with the second surface of the radiating fin in a bending manner. Through the simple radiating design, the invention reduces the complexity of the radiating structure of the light emitting diode unit. The radiating area of the light emitting diode unit is increased so as to improve the radiating efficiency of the light emitting diode unit and further keep the average service life of the light emitting diode unit. Meanwhile, the material cost of the radiating structure of the light emitting diode unit can be reduced.

Description

technical field [0001] The present invention relates to a light-emitting module, in particular to a light-emitting module with heat dissipation function, its reflection cover and its assembly method. Background technique [0002] The well-known light-emitting diode (Light Emitted Diode, LED) has the characteristics of high brightness and small size, and can be installed on various current-carrying devices. Make the tungsten wire emit higher brightness in incandescent state. [0003] In the past, light-emitting diodes were only used for status indication, and there was no need to consider the heat dissipation design after packaging. However, in recent years, light-emitting diode units have been used as backlight sources for liquid crystal displays, and light-emitting diode units require a sufficient number of light-emitting diode chips to provide sufficient of lighting brightness. In addition, the brightness and power of these light-emitting diode chips are greatly improved...
