Problems solved by technology

[0006] The heat dissipation method of high-power LED in the prior art mainly relies on profile radiators. The traditional profile radiators are cumbersome to disassemble and have low heat dissipation efficiency. The multi-piece heat sinks in the prior art are centered on the base and are mainly arranged The top of the seat, so it is necessary to reserve a large installation position, which takes up space

Abstract

The invention relates to the technical field of lamp equipment, in particular to a lamp heat conduction arm and a heat conduction method thereof. The heat conduction arm extends from a light source end to the side face of a light mixing integrated module to achieve lateral extending heat dissipation. The heat conduction method comprises the steps that heat emitted by a light source is guided out upwards, the heat continues to be conducted to the outer side of the light source, and the heat is emitted from the side face of the heat conduction arm. The lamp heat conduction arm and the heat conduction method achieve the effects that the heat dissipation speed is high, the occupied space is small, and the service life of a lamp is prolonged. The light source is reversely mounted, so that the light source is reflected multiple times, and light rays are softer. Due to the arrangement of the heat conduction arm, the mounting space of the top is saved, optical function pieces of different types can be mounted on the top of a light source module assembly to realize different optical functions, and therefore one optical integrated module can realize various different optical effects.

Description

Technical field [0001] The present invention relates to the technical field of luminaire devices, and more particularly to a lamp thermally conductive arm and a thermally conductive method thereof. Background technique [0002] The LED top lamp is a table lamp based on LED (Light Emitting Diode, "LED", LED is a solid-state semiconductor device, which can directly convert electrical conversion to light. The LED is a third-generation lighting technology after incandescent lamps and fluorescent lamps, with energy saving, environmental protection, and reliable feature. [0003] Light efficiency is an important indicator of the performance of LED lighting system. The luminous efficiency of LEDs typically decreases from about 0.2% to 1% as the temperature increases by 1 ° C. As the LED device is aging, the luminous efficiency may be higher than this data with the temperature of the temperature. In some applications, such as car headlights and compact lights, the ambient temperature aro...
