Embodiment Construction

[0016] Such as figure 1 , figure 2 Shown: a shearing and drawing plate type LED lamp heat sink, characterized in that: a number of strip-shaped protrusions 2 are made on the substrate 1, and the two ends of the strip-shaped protrusions 2 are not separated from the substrate 1; the strip-shaped protrusions The shape of 2 is an arc-shaped protrusion; the LED light source 3 is installed on the substrate 1 . If necessary, a wire hole 4 is made on the substrate 1, and the power wire of the LED light source 3 passes through the wire hole 4 to be connected to a power supply.

[0017] The shape of the strip-shaped protrusion 2 is arc-shaped protrusion 5 or triangular protrusion 6 or trapezoidal protrusion 7 or M-shaped protrusion 8 or U-shaped protrusion 9 . During specific implementation, according to the shape of the lamp and the heat dissipation space, the shape of the strip-shaped protrusion 2 can also adopt other shapes.

[0018] Such as Figure 1 to Figure 6 Shown: In order...

Abstract

The invention discloses a sheared and drawn plate type LED (light-emitting diode) lamp radiator, an aluminum plate added with quantum control material is taken as a baseplate, and a stamping machine tool is adopted for shearing and drawing strip-shaped bulges on the aluminum plate. A plurality of the strip-shaped bulges are manufactured on the baseplate, and two ends of each strip-shaped bulge are not separated from the baseplate. A wire through hole is arranged in the position at which an LED light source is mounted on the baseplate. Each strip-shaped bulge is a circular arc-shaped bulge andcan also be a triangular bulge or a trapezoidal bulge or an M-shaped bulge or a U-shaped bulge. The strip-shaped bulges are arranged according to the shape and the size of a lamp, thereby improving heat radiation area to the maximum extent, being good in heat radiation effect and fully meeting heat radiation of a high-power LED lamp. The volume is small and the occupied space is small. The processing can be performed by the ordinary stamping machine tool, the processing technology is simple, the production efficiency is high, no wastes are generated during shearing and drawing process, the utilization rate of materials is high, and the production cost is low.

Description

technical field [0001] The invention relates to a lamp, in particular to a plate-type LED lamp radiator. Background technique [0002] LED lamps are a new type of light source developed in recent years, with small size, light weight, long service life and excellent energy-saving effect. The key technical problem in manufacturing LED lamps is the heat dissipation of LED light sources. At present, the LED heat sinks on the market all use fin-type sheet heat sinks, which have poor heat exchange and air fluidity. The manufacturing process of the radiator is mostly made of aluminum die-casting molding process and extrusion profile cutting process, which has low thermal conductivity, heavy radiator weight, many consumables, low production efficiency and high production cost. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a shearing and drawing plate type LED lamp heat sink, which uses an aluminum plat...
