We investigate a fog-detection CCT control system using low deck lighting as a solution to the forward visibility of pole-type street lamps employed on existing roads. The lighting standards were met with a light source that has less compared with those of pole-type street lamps. The results show that the transmission rate was increased by changing the color temperature by automatically recognizing fog in bad weather and minimizing the phenomenon of lighting. In addition, it was allowed to create a safer and more comfortable driving environment for drivers owing to flicker or light pollution of existing pole-type street lamps. As a result, if lighting is used at a lower level than pole-type street lamps, the accident rate caused by securing the driver’s forward visibility can be reduced sharply and existing problems can be resolved.

In this paper, thermal analysis of HDU (Heat Dissipation Unit) for infrared CCTV is performedby using SolidWorks Simulation (Thermal analysis) package, in order to change the part materials andHDU shape is optimized. Furthermore, HDU disperses the aggregated heat around the LED inside thehousing. The junction temperature of infrared LED checked by HDU check was 65.83℃, 42.02℃,respectively. In addition, the Thermoelement by changing the shape of the HDU was possibly designed andequipped with. Comparison with simulation and prototype measurement results, without HDU model was65.83℃, 61.99℃, respectively. In addition to with HDU model was 42.02℃, 39.01℃, respectively. Only HDUmounted into infrared CCTV is usable in the ordinary house or outdoors. Also HDU with thermal element,fan mounted into infrared CCTV is usable in a blast furnace workplace or high temperature workplace.
