Light-emitting module considering both heat dissipation and light distribution requirements and LED table lamp

Abstract

The invention relates to a light-emitting module considering both heat dissipation and light distribution requirements and an LED table lamp. The light-emitting module comprises an LED lamp panel assembly, a light condenser and a heat dissipation light reflector, wherein the heat dissipation light reflector comprises a light-reflecting part and a fixing part which are integrally formed, the fixingpart is positioned at one end of the heat dissipation light reflector, inclines and overturns inwards, the LED lamp panel assembly is arranged on the inner surface of the fixing part, light rays emitted by an LED lamp on the LED lamp panel assembly are slantwise upward, the light condenser is positioned in front of the LED lamp panel and is used for collecting the light rays emitted by the LED lamp to the light-reflecting face of the heat dissipation light reflector, and the light-reflecting face reflects the light rays for illumination use. The functions of the heat dissipator and the lightreflector are integrated, the device is manufactured in an integral forming manner, and the light-reflecting face can play the role of secondary light distribution and also has the heat dissipation effect, so that the requirements of heat dissipation and light distribution are considered; and the number of the parts is very small, so that the assembly is very easy, meanwhile, the space inside thetable lamp is saved, and finally, the cost of the whole lamp is reduced.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a light-emitting module and an LED desk lamp that meet the requirements of heat dissipation and light distribution. Background technique [0002] In the prior art, there are various forms of LED table lamps, such as direct-down type, that is, the LED light is directly emitted to the working surface; there is a side light source plus a light guide plate, and a reflector is installed on the back of the light guide plate; there is also an LED lamp that shines upward, and a reflector is installed above Reflect the light back down. In order to obtain a suitable light type, it is necessary to perform secondary light distribution on the light of the LED lamp, which requires a light distribution device. The heat of the LED lamp is very concentrated, and it needs to be well dissipated. It needs to be equipped with a heat sink, so the structure of the LED desk lamp is still a bit Compli...

Problems solved by technology

In order to obtain a suitable light type, it is necessary to perform secondary light distribution on the light of the LED lamp, which requires a light distribution device. The heat of the LED lamp is very concentrated, and it needs to be well dissipated. It needs to be equipped with a heat sink, so the structure of the LED desk lamp is still a bit Complicated, with a large number of parts and cumbersome assembly, it is difficult to further reduce the cost
