Abstract

The invention relates to an illumination device (100). The illumination device comprises a lamp tube (1) with two open ends, a light engine (2) arranged in the lamp tube (1), a carrier for carrying the light engine (2), and two end covers (3) for sealing the open ends. The illumination device (100) is characterized by further comprising a diffuser (4), wherein the carrier for carrying the light engine (2) is kept on the diffuser (4), and the diffuser (4) is kept on the inner wall of the lamp tube (1).

Description

technical field [0001] The invention relates to a lighting device, in particular to a retrofit lamp. Background technique [0002] As we all know, LED lighting has irreplaceable advantages, such as energy saving, ultra-low power consumption, close to 100% electro-optical power conversion, the same lighting efficiency can save more than 80% energy than traditional light sources, and its life is longer. In view of the above advantages, more and more people use LEDs as light sources, such as a large number of LED retrofit lamps appearing on the market. This LED retrofit lamp has the outline of a traditional light source such as an incandescent lamp or a lamp tube, so that it can be used as a light source to better adapt to an existing lighting system. [0003] In an existing technical scheme of a retrofit lamp that replaces a traditional lamp tube, the retrofit lamp has a lamp tube made of transparent plastic, and an LED light engine as a light source is arranged inside the la...
