Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] In order to overcome the disadvantages of poor heat dissipation performance of the light bulb itself in the prior art, the present invention provides a light bulb with heat dissipation function, which cleverly utilizes the principle of air convection, and improves the heat dissipation performance of the light bulb by optimizing the internal structure of the light bulb. It can be used in Bulbs that require higher temperature rise, such as LED bulbs with circuit boards, etc.

[0026] Such as figure 1 as shown, figure 1 Shown is the outline view of the bulb of the present inventio...

Abstract

The invention discloses a lamp bulb with a heat dissipation function. The lamp bulb comprises a lamp holder, a light emitting assembly and a heat sink, wherein the lamp holder is provided with air exhaust holes. The heat sink comprises a body and cooling fins, a heat dissipation channel is formed between every two adjacent cooling fins, and at least one air exhaust hole is formed inside each heat dissipation channel. The lamp bulb has the relatively good heat dissipation effect and long service life.

Description

technical field [0001] The invention and the technical field of lighting particularly relate to a light bulb with heat dissipation function. Background technique [0002] Bulbs can convert electrical energy into light energy to provide lighting, which is a necessity in people's daily life and production work. However, when the light bulb converts electrical energy into light energy, it will inevitably convert part of the electrical energy into heat energy, especially for LED lights. Because the inside of the bulb is often equipped with a circuit board or rubber with poor heat resistance, at this time, the electronics in the circuit board Excessive temperature rise of components or rubber will easily cause damage or reduce life span. [0003] At present, there are improvements proposed for the heat dissipation of the light bulb, for example, all the lamp holders of the light bulb are made of metal materials to increase the heat transfer with the outside. However, this will ...
