Light source device

Abstract

The invention relates to a light source device 100. The light source device 100 comprises a roughly inverted T shaped light source base 10, wherein a storing chamber A is inwards concavely formed in one end of the light source base 10, and an electric connecting part 101 which is electrically connected to the light source device 100 is arranged in the storing chamber; a first circuit board 20 which is electrically connected to the electric connecting part 101 is arranged at the upper side of the electric connecting part 101; the first circuit board 20 and a lens module 30 form a light source chamber B; a heat dissipating part 40 and a second circuit board 50 which clings to the outer side of the heat dissipating part 40 are stored in the light source chamber B, and the second circuit board50 is provided with a plurality of side surfaces and a top surface; a plurality of LED light sources 60 are distributed on the second circuit board 50. According to the light source device, an innerhexagonal prism type lens is arranged in the lens module 30 and enables uniform lighting of a cob light source; the light source device is soft in rays and nice in appearance.

Description

technical field [0001] The invention relates to a light source device, in particular to an LED corn cob light source device. Background technique [0002] At present, lamps and lanterns are an indispensable part of everyone's life. At present, most of the electric lamps used in households are ordinary incandescent lamps. But the efficiency of incandescent lamps is very low, only a small part of the consumed electric energy can be converted into light energy, and the rest is mostly lost in the form of heat energy. Moreover, incandescent bulbs will turn black in the later stage, and the light decay is very large, which seriously affects the lighting effect, and its service life usually does not exceed 900 hours. LED lamps have the advantages of environmental protection and energy saving, long life, high luminous efficiency, etc., and have been widely used in various public places and family indoor lighting, and the shapes of LED lamps are also various. [0003] At present, t...

Problems solved by technology

[0003] At present, the maximum light-emitting angle of low-power SMD LEDs on the market is 120 degrees, and there are often defects such as uneven light emission, serious shadows, small lighting range, and low brightness, which limit the application of LED lights to a certain extent.
