Problems solved by technology

[0003] In order to solve this problem, most semiconductor lighting devices are equipped with radiators, which solves the problem of heat dissipation to a certain extent. Connection, because the heat generated by the semiconductor light source is easy to thermally couple with the heat generated by the driving power supply, and it is not easy to dissipate, so that the inside of the semiconductor lighting device maintains a high temperature for a long time, which damages the life of the semiconductor light source

Abstract

The invention provides a semiconductor lighting device. The semiconductor lighting device comprises a semiconductor light source accommodating cavity and a power source accommodating cavity, wherein a semiconductor light source is arranged in the semiconductor light source accommodating cavity; the semiconductor light source accommodating cavity is provided with a heat dissipation part; the heat dissipation part consists of multiple sets of heat dissipation fins; a driving power source is arranged in the power source accommodating cavity; the first side face of the semiconductor light source accommodating cavity is a light-exiting face; the back face of the first side face is a second side face; and the power source accommodating cavity is connected with the second side face of the semiconductor light source accommodating cavity through a connection structure. By adopting the semiconductor lighting device adopting the technical scheme, heat generated by the semiconductor light source can be rapidly transmitted to the heat dissipation part; the heat dissipation efficiency is improved; and the thermal coupling between the heat generated by the semiconductor light source and heat generated by the driving power source is avoided, so that the service life of an LED (Light-Emitting Diode) lamp is greatly prolonged.

Description

technical field [0001] The invention relates to a lighting device, in particular to a semiconductor lighting device. Background technique [0002] Semiconductor lighting is a new type of lighting equipment, which has the characteristics of high luminous efficiency, long life, fast start-up speed, safety, energy saving and environmental protection, shock resistance and pressure resistance, and easy control. During the operation of the semiconductor lighting device, the semiconductor light source will generate a large amount of heat. If the heat is not discharged in time, the service life of the semiconductor light source will be affected, which is also the main factor affecting the service life of the semiconductor lighting device. [0003] In order to solve this problem, most semiconductor lighting devices are equipped with radiators, which solves the problem of heat dissipation to a certain extent. Connection, because the heat generated by the semiconductor light source is...
