Abstract

The invention relates to a lighting device (100), comprising a first light-emitting component (1), a second light-emitting component (1`) and a heat radiating device (2), wherein the heat radiating device (2) is provided with a first heat radiating body (21) and a second heat radiating body (22) arranged around the first heat radiating body (21), the first light-emitting component (1) and the second light-emitting component (1`) are respectively arranged on the top surface (23) and the bottom surface (24) of the second heat radiating body (22), and reflectors used for the first light-emitting component (1) and the second light-emitting component (1`) are arranged on the first heat radiating body (21). According to the lighting device disclosed by the invention, the lighting effect is good, and the omni-directional lighting is specifically realized; and the lighting device and the lamp provided with the lighting device have the advantages that the manufacturing technique is simple, the cost is low, and the heat radiating capability is remarkably improved.

Description

technical field [0001] The invention relates to an illuminating device and a lamp with the illuminating device. Background technique [0002] With the development of lighting technology, omnidirectional lighting devices have gradually become a new research field. Known omnidirectional lighting devices, for example: have a complex heat dissipation structure, and arrange a large number of LEDs in a fully enclosed form on the surface of the lighting device; or have a remote fluorescent lamp housing; or have a light guide structure; Reflective structure inside the shell. [0003] Although the above-mentioned type of omnidirectional lighting device 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, relatively high heat is generated by the light emitting module inside the lighting devi...
