Problems solved by technology

[0003] Although the omnidirectional lighting device of the above type can basically achieve the desired lighting effect, the manufacturing cost or material cost is quite expensive
The brightness of the omnidirectional lighting device can be improved by increasing the power of the light source, but at the same time inside the lighting device, higher heat will be generated through the light emitting module
If timely and effective cooling measures cannot be taken for the lighting device, its service life may be affected

Abstract

The present invention relates to an illuminating device (100), comprising a first light-emitting assembly (1), a second light-emitting assembly (1') and a heat dissipating device (2), wherein the heat dissipating device (2) comprises a first heat sink (21) and a second heat sink (22) provided to surround the first heat sink (21), the first light-emitting assembly (1) and the second light-emitting assembly (1') are arranged on a top surface (23) and a bottom surface (24) of the second heat sink (22), respectively, and the first heat sink (21) is provided with a reflector for the first light- emitting assembly (1) and the second light-emitting assembly (1'). The illuminating device of the present invention has the advantage of a good illuminating effect, especially realizing the omnidirectional illumination, and also has the advantages of a simple structure, a low cost and prominently improved heat dissipating capabilities.

Description

technical field [0001] The present invention relates to a lighting device and a lamp having the lighting device. Background technique [0002] With the development of lighting technology, omnidirectional lighting devices have gradually become a new research field. For example, the known omnidirectional lighting device has a complex heat dissipation structure, and a large number of LEDs are arranged in a fully enclosed form on the surface of the lighting device; or a remote fluorescent lamp housing; or a light guide structure; Reflective structure inside the shell. [0003] Although the above-mentioned type of omnidirectional lighting device can basically achieve the expected lighting effect, the manufacturing cost or material cost is quite expensive. The brightness of the omnidirectional lighting device can be improved by increasing the power of the light source, but at the same time, inside the lighting device, higher heat is also generated by the light emitting module. ...
