High-power LED (light-emitting diode) lamp radiator

Abstract

The invention discloses a high-power light-emitting diode (LED) lamp radiator which comprises a radiating unit with V-shaped cross sections, wherein side views of the two V-shaped faces of the radiating unit are respectively rectangles; a plurality of fins are arranged between the two V-shaped faces; and the direction of the fins is parallel with or coincide with the equally-dividing face of the included angle of the V-shaped faces; the left external side of the V-shaped faces is provided with a tenon, and a mortise is arranged at the position of the external side of the V-shaped faces, which corresponds to the tenon; and a first ornamental engraving structure is arranged near the peaks of the V-shaped faces and comprises a first arc-shaped notch concaving into a left V-shaped face and a crescent protruding block protruding from the right V-shaped face. The radiating unit of the high-power LED lamp radiator is molded and manufactured by extruding aluminum alloy and connected through the mortise and tenon joint, radiating shapes and radiating areas can be combined randomly, thus the high-power LED lamp radiator is good in radiating effect, and adapts to radiating or LED lamps with high powers of 300-500W.

Description

technical field [0001] The invention relates to a radiator used in LED lamps used in stage lighting, TV, film and photography places. Background technique [0002] Light diodes (LEDs) have the characteristics of thinness, power saving, environmental protection, fast lighting response, and long life. In addition, the light output and power continue to increase despite the continuous reduction in cost, which promotes the increasing market acceptance of LED lighting. From traffic signal indicators to large-size backlights, it has progressed to various lighting applications such as headlights, indoor and outdoor lighting fixtures, etc. At present, the luminous efficiency of LED has exceeded 100 lumens per watt, enough to replace power-consuming incandescent lamps, halogen lamps, and even fluorescent lamps and high-pressure gas discharge lamps. At present, there are two types of high-power LED light sources, one is array distributed, and the other is integrated high-power LED li...

Problems solved by technology

[0005] Heat dissipation fins mainly rely on conduction and natural convection to dissipate heat, which is the most common heat dissipation method. By increasing the heat dissipation area and matching the design of air ducts and opening holes, the conduction and natural convection capabilities are improved. The disadvantages are: (1) dense arrangement The aluminum sheets are easy to accumulate dust and block the gaps between the aluminum sheets, resulting in no air circulation and eventually losing the heat dissipation function

(2) The aluminum sheet is thin and soft, which is easily deformed or folded together due to touch, which affects the heat dissipation function and appearance

These radiators must be separately molded into different specifications for LEDs of different powers and sizes, which increases the production cost
