Temperature alarm structure of high power led ground light

Abstract

The invention relates to the field of LED lighting lamps, in particular to a temperature alarm structure of a high-power LED floor lamp, comprising a lamp body of the high-power LED floor lamp, and is characterized in that it further comprises a controller, a buzzer, a large a power LED light source and a temperature sensor; the controller is respectively electrically connected with the temperature sensor and the buzzer; the temperature sensor is close to the high-power LED light source. The temperature sensor is electrically connected to the input end of the controller. When the body of the high-power LED floor lamp exceeds the preset threshold value of the temperature sensor, the temperature sensor sends a "too high temperature" signal to the controller, and the output end of the controller is connected to the controller. The buzzer is electrically connected, so the controller transmits a "temperature too high" signal to the buzzer, and the buzzer starts to work, producing a buzzer. Therefore, the present invention can issue an alarm when the temperature inside the high-power LED floor lamp is too high.

Description

[0001] technical field [0002] The present invention relates to the field of LED lighting lamps, in particular to a temperature alarm structure for high-power LED ground lamps. Background technique [0003] LED ground lights are widely used in lighting of roads, traffic, lawns, landscapes, etc. Among them, the rated current of the LED light source of the high-power LED ground lights is much higher than that of ordinary LED lights, and the heat generation is also higher than that of ordinary LED lights, and the temperature is too high. It will affect the working performance of high-power LED ground lights and damage high-power LED light sources. For high-power LED ground lights, a reasonable heat dissipation design must be adopted. However, the use of heat dissipation design cannot guarantee that the internal temperature of high-power LED ground lights is within a reasonable range. Contents of the invention [0004] The purpose of the present invention is to overcome the ab...
