Illumination device

Abstract

The invention discloses an illumination device. The illumination device comprises a shell, a radiation component arranged on one end of the shell, a light source component which is in thermal contact with one end of the radiation component, an optical component arranged on the other end of the light source component and a driving power component, wherein the light source component and the shell are separately located on two ends of the radiation component; the radiation component is arranged outside the illumination device, and a plurality of passages which are used for communicating the inside with the outside are arranged on the illumination device; and the passages penetrate through the shell and the radiation component, so that heat emitted by the light source component in the illumination device can be effectively and rapidly dissipated through the passages. Therefore, the illumination device has the characteristic of good radiation effect, so that the service life of the light source component in the illumination device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lighting, and in particular relates to a lighting device. Background technique [0002] Lamps, especially high-power lamps, after being turned on and used for a long time, the temperature of the entire lamp will be very high. If the lamp cannot effectively dissipate heat, the service life of the lamp will be greatly shortened. Therefore, high-power lamps generally add a heat dissipation structure between the lamp housing and the mask. The current heat dissipation structure is mostly made of aluminum alloy, with many fins closely arranged on it, and the structure is complex, resulting in the weight of the entire lamp. It is very large, which causes the weight of the whole lamp to be large, exceeding the weight that the lamp holder of the lamp (such as the standard lamp holder E27 or E40) can carry, so the lighting lamp also needs to be equipped with a safety chain.

[0002] Lamps, especially high-power lamps, after being turned on and used for a long time, the temperature of the entire lamp will be very high. If the lamp cannot effectively dissipate heat, the service life of the lamp will be greatly shortened

Therefore, high-power lamps generally add a heat dissipation structure between the lamp housing and the mask. The current heat dissipation structure is mostly made of aluminum alloy, with many fins closely arranged on it, and the structure is complex, resulting in the weight of the entire lamp. It is very large, resulting in the weight of the whole lamp, which exceeds the weight that the lamp holder (such as the standard lamp holder E27 or E40) can carry, so the lighting lamp needs to be equipped with a safety chain

The safety chain is connected between the mounting frame and the light source, which not only increases the cost of high-power lamps, but also makes it difficult to replace the light source
