Embodiment Construction
[0015] An electric heating defrosting device of the present invention will be further described below in conjunction with the accompanying drawings. like figure 1 , figure 2 As shown, an electric heating defrosting device includes a heating element 1, and a wire 2 is electrically connected to the heating element 1 to supply power to the heating element 1 through a power supply. The heating element 1 can share the same power supply with the traffic signal light. It can also be powered by a separate power supply, and in order to make the electrical connection between the heating element 1 and the wire 2 reliable, the wire 2 can be welded on the heating element 1;
[0016] see figure 2 , because traffic lights generally work in the open air, in order to avoid electric leakage of the heating element 1, an insulating cover 3 is sheathed on the outside of the heating element 1, and the insulating cover 3 includes an upper insulating layer 4 and a lower insulating layer 5, and th...

The invention provides an electrical heating defrosting device. A heating body is sleeved with an insulation cover, after an upper insulation layer and a lower insulation layer are bonded, the middle portion forms a containing cavity for containing a heating body, an upper heat conduction layer is fixed onto the upper insulation layer, a lower heat conduction layer is fixed onto the lower insulation layer, and a bonding layer is fixed onto the lower heat conduction layer; a controller for controlling the heating body to work or stop is connected onto a wire in series, and a temperature detector is fixed onto the lower insulation layer; through the heating body, the insulation sleeve, the upper insulation layer and the lower heat conduction layer, the heating body can heat an LED lamp circuit board of a traffic signal lamp and a shell of the traffic signal lamp, the technical problem that an LED lamp can not be opened normally at low temperature is solved, meanwhile, after the heating body heats the shell of the traffic signal lamp, the accumulated snow or frost accumulated on the shell can be melted, and the traffic signal lamp still can indicate normally under a low temperature condition.
Description
technical field [0001] The invention relates to an electric heating defrosting device. Background technique [0002] Traffic signal lights are a kind of traffic command device, which play a role in commanding vehicles to drive in an orderly manner. Traffic lights in the prior art generally use LED lights as light-emitting modules. LED lights have the advantages of long service life and low energy consumption and are widely used; however, LED lights may have the disadvantage of being unable to start at low temperature, that is, When the temperature is too low, the LED light may not light up normally; [0003] In addition, the structure of the traffic lights in the prior art is simple, and the working environment is harsh; especially in winter, under low temperature conditions, snowflakes may accumulate on the outer shell of the traffic lights. At this time, even if the LED lights can be normally lit, but Due to the existence of snow, the traffic lights are still unable to i...
