Embodiment Construction

[0025] figure 1 It is a perspective view of the heat sink according to the first embodiment of the present invention. The heat dissipation device 100 includes a base 1 and at least a pair of support arms 2 extending from two sides of the base 1 . A part of the light source 11 serving as a heat source can be placed in the first area 5 on the base 1 , and another part of the light source 11 serving as a heat source can be placed in the second area 6 on the support arm 2 . The heat emitted by the light source 11 can be directly transferred to the base 1 and the support arm 2, so that the light source 11 can be dissipated by utilizing the heat dissipation characteristics of the heat dissipation device itself.

[0026] Depend on figure 1 It can be recognized that the abutment 1 is preferably designed with a regular trapezoidal cross-section, that is to say, the abutment 1 comprises a horizontal first top surface A1, a bottom surface A2 parallel to the first top surface A1 and con...

Abstract

The invention relates to a heat dissipation device (100) for an omnidirectional lighting device, which is characterized in that it comprises a base (1) and at least a pair of support arms (2) extending from both sides of the base (1), The base (1) is provided with a first area (5), and a pair of support arms (2) are provided with a second area (6) opposite to each other, and the first and second areas (5, 6) are used for arranging heat sources , wherein the second regions (6) are inclined towards the first regions (5) respectively. The heat dissipation device of the present invention has the characteristics of low cost, simple structure, easy installation and good heat dissipation effect. In addition, the present invention also relates to an omnidirectional lighting device installed with the cooling device and a retrofit lamp.

Description

technical field [0001] The invention relates to a heat dissipation device for an omnidirectional lighting device, an omnidirectional lighting device equipped with the heat dissipation device, and a retrofit lamp. Background technique [0002] With the development of lighting technology, omnidirectional lighting devices have gradually become a new research field. The omnidirectional lighting device generally refers to a lighting device that can illuminate a large area and has uniform light distribution. The light diffusion angle (light distribution angle) of the omnidirectional lighting device in the prior art can already reach 320° Spend. Especially in the US market, many lighting devices must be designed as energy-saving lighting devices in order to meet the "Energy Star" standard. The current research and development goal is to make the omnidirectional lighting device fully meet the "Energy Star" standard, and have a low bill of materials (BOM) and low manufacturing cost...
