Illuminating lamp capable of achieving heat dissipation at front end

Abstract

The invention provides an illuminating lamp capable of achieving heat dissipation at the front end. The illuminating lamp capable of achieving heat dissipation at the front end comprises a base, a circuit mechanism, a supporting frame, a lamp shade, a heat dissipation pipe and an LED module. The base comprises a base plate and an installation cover, and the installation cover is arranged on the base plate in a covering mode. The supporting frame is installed on the installation cover. The lamp shade end is connected with the supporting frame. A heat dissipation opening is formed in the second end of the lamp shade. The first end of the heat dissipation pipe is fixed to the first end of the lamp shade, the heat dissipation pipe is hollow, and the second end of the heat dissipation pipe communicates with the outside. A plurality of heat dissipation strips are arranged in a heat dissipation cavity. The two ends of each heat dissipation strip are both connected with the inner side of the heat dissipation pipe, and the heat dissipation pipes form a net-shaped structure. The LED module comprises a plurality of LED sub light sources, and the LED sub light sources are arranged on the outer side wall of the heat dissipation pipe. According to the illuminating lamp capable of achieving heat dissipation at the front end, the heat dissipation cavity communicating with the outside is formed in the heat dissipation pipe, and the heat dissipation opening is formed in the lamp shade so that heat generated by the LED sub light sources can be dissipated to the outside more rapidly and timely, and the heat dissipation performance is good.

Technical field [0001] The invention relates to the technical field of lighting and heat dissipation, and in particular to a front-end heat dissipation type lighting lamp. Background technique [0002] At present, in existing lighting devices, the main heating elements are generally PCB aluminum substrates that directly contact the light source, and a circuit board that drives the light source to emit light. In order to integrate the lighting device, the PCB aluminum substrate and the circuit board are usually placed inside the lighting device. [0003] Generally, PCB aluminum substrates and circuit boards generally transfer heat to the air through the housing. The lighting device adopting the above structure to dissipate heat has low heat conduction efficiency and slow heat dissipation speed, so that the lighting device is prone to a safety hazard of excessive heat load of the internal circuit mechanism due to poor heat dissipation. Summary of the invention [0004] Based on this...
