Abstract

The invention relates to a heat dissipation structure of a light-emitting lamp body, which includes a glass shell and a heating component arranged in the glass shell; wherein the heating component and the glass shell are in close contact, and the area of ​​the closely contacting part is maximized. The present invention also relates to a lighting device with the heat dissipation structure and a method for manufacturing the lighting device. Adopting the heat dissipation structure of the light-emitting lamp body, the corresponding lighting device and its manufacturing method are cheap and economical, and play the dual functions of insulation and heat transfer; ensure that the glass shell and the heat-generating parts have as large a contact area as possible, and become the main heat sink. The load transmission path, heat-conducting silicone potting can ensure high-efficiency heat transfer, and the metal-based circuit board further improves the efficiency of heat transfer, effectively avoiding excessive internal temperature of the luminous lamp body, energy saving, safety and environmental protection, and prolonging the service life. The structure is simple and practical. The manufacture is convenient and fast, the working performance is stable and reliable, and the scope of application is relatively wide, which brings great convenience to people's work and life.

Description

technical field

[0001] The present invention relates to the field of light-emitting lighting, in particular to the field of light-emitting lighting equipment and a manufacturing process thereof, in particular to a heat-dissipating structure of a light-emitting lamp body, a corresponding lighting device and a manufacturing method thereof. Background technique

[0002] With the continuous progress of human civilization and the continuous development of science and technology, lighting devices have long been known. In general, this type of lighting device includes a housing and a light-emitting component disposed within the housing.

[0003] With the advancement of technology, LED has been able to provide enough light energy for lighting purposes. In order to reduce the energy consumption of lighting and reduce carbon dioxide emissions, in order to promote the continuous advancement of the alternative light source market, LED light sources have been used to replace incandescent...

Examples

Embodiment Construction

[0068] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0069] see Figure 1a , 1b As shown, the heat dissipation structure of the luminescent lamp body includes:

[0070] (1) glass housing 1;

[0071] (2) The heating component 2 arranged in the glass housing 1;

[0072] Wherein, the heat-generating component 2 is in close contact with the glass casing 1, and the area of ​​the part in close contact is maximized.

[0073] Wherein, there is a heat transfer contact portion 11 on the inner wall of the glass housing 1, and the heat transfer contact portion 11 is in close contact with the heat-generating component 2; the heat transfer contact portion 11 can be at least in the following two forms:

[0074] (a) see Figure 2a As shown, it is an annular boss, and the bottom surface of the annular boss is in close contact with the heating component 2; this structure is easy to manufacture, and is more d...
