Figure 4 And Figure 5 .

[0036] The light emitting direction of the warning lamp with heating function is defined as the front direction, and the direction of the base 120 is defined as the lower direction.

[0037] It should be noted that the heat transfer cover 320 conducts the heat generated by the heat generating element 310 to the outside of the heat generating module 300, so that the accumulated snow, ice or frost on the outside of the warning lamp is melted. When the minimum distance between the heat transfer cover 320 and the shell 110 is controlled within the above range, the heat can be effectively and rapidly conducted to the shell 110, and the heat accumulation in the lamp is avoided. The heat generating element 310 of the utility model is fixedly assembled to the lower bottom surface of the heat transfer cover 320, and the heat generating element 310 of the utility model is a PTC heating sheet.

[0038] The light emitting module 200 is provided with a plurality of groups of light sources 210 and supports 220, each group of light sources 210 is arranged at the back of a light hole 330, and all light sources 210 are fixed to the support 220, the support 220 is in a tubular structure, and the heat generating element 310 is located at the upper center of the tubular structure.
