Abstract

The invention discloses a mute exhibition ceiling lamp. The mute exhibition ceiling lamp comprises a lampshade, a base and a supporting frame; the lampshade is of a hemispherical structure; the base is of a tubular structure with openings in the two ends; the lampshade is fixed to the lower end of the base and is connected with the base; the supporting frame is located in a space defined by the lampshade and the base and connected with the lower portion of the base; the supporting frame is of a conical tubular structure which is open in the upper and lower part and closed in the middle part; asealing ring is arranged between the upper portion of the supporting frame and the base; a communicating hole is formed in the lower portion of the supporting frame; and a plurality of air inlet holes are formed in the edge of the upper end face of the lampshade. External air is introduced through the edge of the lampshade; a light source is arranged on the supporting frame; and after the light source emits heat, air in the supporting frame and the base is heated by heat, so that hot air rises automatically; and therefore, negative pressure is generated in the lampshade so as to continuouslysuck in cold air, the effect of automatic heat dissipation is achieved, a fan does not need to be additionally arranged, and quietness is kept while heat dissipation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of lighting electrical equipment manufacturing, in particular to a silent exhibition chandelier. Background technique [0002] Among the lighting devices commonly used by people, compared with incandescent lamps, LED lamps have the advantages of low energy consumption and long service life, and have been widely used in industrial production and people's lives. However, LED lights also generate heat during the process of emitting light. If the heat dissipation effect is not good, it will accelerate the aging of lamp beads and phosphors, thereby affecting the service life of LED lights. In the prior art, air-cooling is usually used to dissipate heat, but the air-cooling method is easy to accumulate dust, and the noise is relatively large. When there is too much dust, it will also cause dust to accumulate in the lampshade, causing damage to the internal components and causing damage to the lighting fixture. , ...
