[0002] The existing radiators used for downlights with expandable radiators are generally fixed in shape due to design defects. In order to increase the heat dissipation area, cooling fins are generally densely distributed on the outer wall of downlights with expandable radiators. However, during the heat dissipation process, the heat is concentrated on the outer wall of the downlight with an expandable radiator, and the heat dissipation effect is not ideal
Moreover, the existing downlights with expandable radiators must be fixed by snap springs, which is troublesome to install and disassemble.
[0003] Therefore, the existing downlight with expandable radiator needs to be further improved

Abstract
The invention discloses a down lamp with an extensible radiator. The down lamp comprises a radiating barrel body, wherein a light reflecting cover is connected at the upper end of the radiating barrel body; a plurality of radiating fins are arranged on the outer wall of the radiating barrel body; a radiator main body capable of rotating relative to the radiating barrel body is arranged in the radiating barrel body; a cavity is formed in the radiator main body; the radiating fins are uniformly arranged on the inner wall of the radiator main body; a plurality of radiating thin sheets which can be huddled up on the radiator main body are arranged on the outer wall of the radiator main body; a plurality of guide slots are formed in the radiating barrel body; the radiating thin sheets are arranged in the guide slots; radiating holes are densely distributed in the radiating thin sheets; a mounting slot is formed in the upper end part of the radiator main body; an LED (light-emitting diode) chip is arranged in the mounting slot; a limiting table is arranged on the end part of the light reflecting cover; light-transmitting glass is arranged in the limiting table; and a positioning pulling sheet capable of locking the light-transmitting glass on the light reflecting cover is arranged on the light reflecting cover. The down lamp is simple in structure; and the radiator can be extended, is good in radiating effect and convenient in mounting and dismounting.
Description
technical field [0001] The invention relates to a downlight with an expandable radiator. Background technique [0002] The existing radiators used for downlights with expandable radiators are generally fixed in shape due to design defects. In order to increase the heat dissipation area, cooling fins are generally densely distributed on the outer wall of downlights with expandable radiators. However, during the heat dissipation process, the heat is concentrated on the outer wall of the downlight with an expandable radiator, and the heat dissipation effect is not ideal. Moreover, the existing downlights with expandable radiators must be fixed by snap springs, which is cumbersome to install and disassemble. [0003] Therefore, the existing downlight with an expandable radiator needs to be further improved. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art, and provide a downlight with an expandable radia...
