The invention relates to the field of lamps. The invention provides a lamp with an overheating protection mechanism, which mainly includes a base board installed in the housing of the lamp, an electrically connected light-emitting diode and an overheating protection unit are arranged on the base board, and the overheating protection unit is directly attached to the base board with a heat conduction plane. Therefore, when the light-emitting diode operates and generates abnormal overheating, the heat energy of the light-emitting diode is directly conducted to the substrate, and then the heat of the substrate is directly conducted to the overheating protection unit through the heat conduction plane, so that the overheating protection unit can be directly and rapidly reacted by heat, and Accordingly, the light-emitting diodes are stopped to avoid overheating and damage caused by the continuous operation of the light-emitting diodes.
Description
Technical field [0001] The invention provides a lamp with an overheat protection mechanism, which is related to the lamp. Background technique [0002] LED lamps have excellent characteristics of low power consumption and long working life, so LED lamps have been widely used at present, and in order to meet different needs and diversification of applications, there is a high power and high brightness on the market Although the high-power and high-brightness LED lamps can meet the needs of high-brightness, high-power operation also generates high heat, which leads to the need for heat dissipation; [0003] In addition to providing the necessary passive heat dissipation effect, the high-power LED lamps on the market will also be equipped with an overheating protection device, through which the overheating protection device actively generates a protection mechanism that stops operation when the whole lamp is overheated. , To achieve the effect of protecting the parts; and the overhea...
