Embodiment Construction

[0015] Depend on Figure 1 ~ Figure 3 As shown, the present invention includes a column-type heat conductor 1, a heat transfer sheet 2, a heat dissipation housing 3 and a high-power LED10, and a column-shaped hole 101 is opened in the column-type heat conductor 1. In order to quickly reduce the temperature of the high-power LED10, the A thermal conductor 9 is inserted into one side of the column-shaped hole 101 , and a high-power LED 10 is fixed on the end faces of the column-shaped thermal conductor 1 and the thermal conductor 9 .

[0016] The shape of the so-called heat conductor 9 is an aluminum sheet, an aluminum rod, a copper sheet, a copper rod, a copper tube with one side closed, and a heat pipe. Because of the power of the high-power LED 10, its calorific value is different, so one of the above forms can be selected according to the structure of the lamp and the power of the LED used. Generally, when the power of the LED lamp is relatively high, the copper material is...

Abstract

The invention discloses a vertical column shaped LED radiator, comprising a vertical column shaped heat-conductor, a heat transmission sheet, a heat dissipation shell and a large power LED; the vertical column shaped heat-conductor is internally provided with a vertical column shaped hole; a heat conductor is plugged in one side of the vertical column shaped hole; and furthermore, the large power LED is fixed on the end surface of the vertical column shaped heat conductor and the heat conductor. The external circumference of the vertical column shaped heat conductor is longitudinally provided with more than one heat transmission sheet and ribs; two sides of the heat transmission sheet are respectively provided with a wing; the end section of the heat transmission sheet is connected with the heat dissipation shell which is provided with a connection hole and a fin; and the ribs and the wings between two heat transmission sheets are longitudinally arranged in parallel. The vertical column shaped LED radiator adopts aluminium materials with good heat conduction performance, is integrated into a whole by extrusion process, can be used by cutting, has compact structure, reduces the cost, and can comply with various high-power or other typed semiconductor illumination lamps such as development streamer lamps, lamps embedded in ceilings, suspension lamps, automobile headlamps, street lamps and the like.

Description

technical field [0001] The invention relates to an electronic heat sink, in particular to a column type LED heat sink. Background technique [0002] Semiconductor electric light source is a kind of electric light source without filament. It is a light-emitting device that directly converts electrical energy into light energy. It is called a light-emitting diode, also known as a semiconductor lamp, and is referred to as LED in English. Semiconductor lighting is considered to be a new energy-saving light source for lighting in the 21st century. LED not only saves energy, but also has the characteristics of long life, small size, safety, environmental protection, maintenance-free, and easy control. LEDs can already replace traditional light sources in many places, especially the emergence of high-power LEDs, which has accelerated the speed at which LEDs replace traditional lighting sources, and has also made the large-area application of LEDs in indoor lighting a reality.
