Illuminator with auxiliary radiating function

Abstract

A lighting device with assistant function of heat radiating is formed by a shell being a closed space and using one end surface as transmission surface as well as a lighting module set in shell with multiple lighting elements on a circuit board as which its peripheral edge is clutched in shell for better heat radiation and easier assembly.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device with auxiliary heat dissipation function which can achieve good heat dissipation effect and easy assembly. Background technique [0002] Figures 1 and 2 show a conventional illuminating device 1 having both photography and lighting functions. The lighting device 1 has a housing 11 composed of a body 111 and a cover 112 , a light emitting module 12 , a camera module 13 and a fixing piece 14 . The light emitting module 12 has a circuit board 121 and a plurality of light emitting diodes 122 . The camera module 13 also has a circuit board 131 and a lens 132 , the lens 132 is disposed in the center of the circuit board 131 and passes through the circuit board 121 of the light emitting module 12 (as shown in FIG. 2 ). As shown in FIG. 2 , when assembled, the circuit board 121 of the light-emitting module 12 is screw-locked on the two copper pillars 141 on one surface o...

AI Technical Summary

Problems solved by technology

The heat will be transferred from the LED 122 or the pins of the electronic components to the circuit board 121. Due to the confined space in the casing 11 and the poor heat conduction of the circuit board 121 due to the glass fiber, it is difficult for the heat to pass through the surface of the circuit board 121. Only a small part can pass through the two copper pillars 141 to the fixed piece 14, resulting in poor heat dissipation efficiency, and high temperature will be generated when the light emitting module 12 is working.

The high temperature when the light-emitting module 12 is working will not only shorten the life of the light-emitting diode 122, or even burn it out in a short period of time, but also affect the life of the camera module 13.

Furthermore, because the heat dissipation efficiency of the existing lighting device 1 is not good enough, the number of light emitting diodes 122 that can be assembled is also limited, such as 12 to 18, so that the amount of light emitted by the light emitting module 12 is also limited, making photography difficult. The night vision effect of module 13 is not good, and the photographic image is not clear

In addition, since the light-emitting module 12 needs to be locked on the fixing piece 14 by screws, it also causes consumables and labor for assembly.
