Abstract
The utility model discloses a light supplementary camera which comprises a camera charge coupled device, an LED light supplementary module, and a housing. The housing comprises a cylindrical middle frame with openings at two ends of the cylindrical middle frame, a front cover, a back cover and a sunlight shielding cover. The camera charge coupled device and the LED light supplementary module are assembled inside the cylindrical middle frame which is also provided with a hot tube therein. One part of the hot tube is closely adhered to the LED light supplementary module while the rest part of the hot tube is flexibly joined to the housing. The light supplementary camera of the utility model adopts a hot tube into its constituting structure for dispersing heat away; in this way, a good temperature reducing effect can be achieved because the hot tube is a good phase transition heat transferring component with high heat conductivity and enables a large amount of heat to be transferred through its small cross section to a long distance without externally exerted force. The camera also takes advantage of evaporation and condensation of liquid prone to evaporate within a fully enclosed vacuum tube housing to transfer heat. With a good heat radiation performance, a simple structure and high practicability, the tube is capable of ensuring a light supplementary camera cools down rapidly so as to ensure the camera functions normally.
Description
[technical field]
