One-to-one heat dissipation LED module

Abstract

The invention discloses a one-to-one heat dissipation LED module. The one-to-one heat dissipation LED module comprises a lampshade, a heat dissipation component, a substrate and a plurality of LED light sources packaged on the substrate, wherein the lampshade is in matched connection with the heat dissipation component to form an accommodating space, the substrate is arranged in the accommodating space, the heat dissipation component comprises a heat dissipation base plate fixedly connected with the lampshade, the substrate is attached to the bottom of the heat dissipation base plate, and a plurality of heat dissipation units in one-to-one correspondence to the LED light sources in position are arranged on the upper portion of the heat dissipation base plate. In work, independent heat dissipation is conducted on each LED light source by the corresponding heat dissipation unit, the effective area of each heat dissipation fin is fully utilized, heat conduction velocity and heat convection coefficient are increased, heat dissipation of all parts is more uniform, and heat dissipation performance is better; furthermore, due to the fact that each heat dissipation unit conducts heat dissipation on a single LED light source, the area of each heat dissipation fin can be reduced, and therefore the whole size is smaller and the whole weight is lower.

Description

technical field [0001] The invention relates to the technical field of LED modules, in particular to a one-to-one heat dissipation LED module. Background technique [0002] LED has many advantages such as environmental protection, energy saving, and long life, and has gradually become the best choice for energy-saving renovation of road lighting. However, since the LED light source is installed inside the closed body, a large amount of heat will be generated during operation. If it cannot be discharged in time, the temperature of the P-N junction will rise rapidly, which will accelerate the light decay of the LED, and even lead to devastating thermal breakdown. Therefore, LED lamps need to be provided with heat dissipation components for heat dissipation. [0003] In the existing LED lamp heat dissipation technology, each LED module usually shares a heat dissipation unit, which cannot fully utilize the effective area of ​​the heat dissipation fins, resulting in slow heat co...
