Embodiment Construction

[0028] see Figure 1-3 , is the traffic signal lamp 10 according to the first embodiment of the present invention. The traffic signal lamp 10 includes a housing 11, at least one light source module 12, a light-transmitting lens 13 corresponding to the front of the light source module 12, and a transparent The protective cover 14 in front of the optical lens 13 , the temperature detection element 18 installed on the protective cover 14 and the heating element 16 installed on the protective cover 14 .

[0029] The casing 11 is arranged in a box shape, and a light outlet is provided at the front end for the signal light of the light source module 12 to emit. The upper part of the front end of the housing 11 protrudes forward than the lower end, so that the light outlet is inclined to reduce wind and snow from adhering to the protective cover 14 .

[0030] The light source module 12 is installed inside the casing 11 , wherein the number of the light source modules 12 is not limit...

Abstract

A traffic signal lamp, comprising at least one casing, a light source module, and a light-transmitting lens relatively arranged in front of the light source module, the lamp also includes a transparent protective cover, a temperature detection element and a heating element installed on the protective cover The transparent protective cover is installed on the light output end of the lamp. When the temperature detection element detects that the temperature of the external environment is lower than a set value, it controls the heating element to turn on to melt the snow or ice attached to the outer surface of the protective cover. The traffic signal lamp of the present invention senses the temperature of the outside world through the temperature detection element to melt the ice and snow on the protective cover at the light output end, ensuring that the lamp can work safely in ice and snow weather.

Description

technical field [0001] The invention relates to a traffic signal lamp, in particular to a traffic signal lamp with a snow removal structure. Background technique [0002] At this stage, the weather changes seriously, especially the snowstorm, which has a great impact on outdoor lamps. Especially traffic lights, because of snowing often causes snow to pile up on the outer cover of traffic lights, even accumulates into ice cube. Snow attached to the light-transmitting lenses of signal lights can easily cause poor vision or unclear signals, and even traffic accidents. In addition, due to the large number of signal lights and their height, it is difficult to manually remove snow or ice from the signal lights. Contents of the invention [0003] In view of this, it is necessary to provide a traffic signal lamp that can automatically remove snow to improve the traffic safety of passers-by. [0004] A traffic signal lamp, comprising at least one casing, a light source module, a...
