Abstract
The invention provides an accumulated snow prevention device for a light emitting diode (LED) lamp, which is used for preventing accumulated snow from shielding the display of a lamp signal of the LED lamp. The device comprises an LED light-emitting unit, an external element and at least one heat-conducting element, wherein the LED light-emitting unit is arranged in an outer lamp shell; the external element is arranged on the outer side of the LED light-emitting unit and is fixed on the outer lamp shell; and the at least one heat-conducting element is connected between the LED light-emitting unit and the external element in a heat-conducting mode, so that the heat of the LED light-emitting unit is conducted to the external element. The heat-conducting element conducts the heat produced when the LED light-emitting unit emits light to the external element, so that the external element and/or the outer lamp shell at the periphery of the external element produces a high temperature to melt the accumulated snow on the external element and the outer lamp shell; therefore, the phenomenon that the LED light-emitting unit cannot display the lamp signal outwards because the accumulated snow covers the outer lamp shell is avoided.
Description
Technical field
The present invention refers to a kind of conductive structure of the LED of utilization lamp especially about a kind of anti-accumulated snow device of LED lamp, the LED lamp is caused the anti-accumulated snow device of the LED lamp of the influence of covering the cresset demonstration in order to the accumulated snow that melts on the outer lamp housing to prevent accumulated snow.
Background technology
General LED lamp has been applied on traffic signal light, warning lamp or the car light widely to be used, for example establish traffic signal light, warning lamp on road cross or the specific road, advancing and stop or the pedestrian is provided, drives caution attention effect in order to commander pedestrian, vehicle, to promote the security of road traffic, keep good traffic order, and reduce the traffic accident generation, in addition the LED lamp is used on the vehicle, except can be, and prolong service life of car light significantly with the low electric power consumption amount.
