Over-temperature protection device for LED lamps connected in parallel

Abstract

The invention discloses an over-temperature protection device for LED lamps connected in parallel. The over-temperature protection device comprises an LED lamp set, the LED lamp set comprises a lamp box, a plurality of lamp grooves are formed in the lamp box, sliding blocks are arranged in all the lamp grooves, sealing blocks are arranged in the sliding blocks, sealing covers are arranged at the upper ends of the sealing blocks, and the LED lamps are arranged in the sealing covers. A cooling assembly is arranged on the lower side of each sliding block, a light condensation assembly is arrangedon the side face of each LED lamp, a power-off assembly is further arranged in each LED lamp, the cooling assemblies are used for cooling the LED lamps when the LED lamp set is used, the light condensation assemblies condense weak light during cooling, and the situation that the light brightness is insufficient when the LED lamps are heated is prevented. The power-off assemblies are used for switching off a circuit for the LED lamps when the LED lamps are in an over-temperature state, so that the LED lamps are prevented from continuing to be heated. The over-temperature protection device hasthe characteristics that local rapid cooling can be achieved, automatic light supplementing is achieved, emergency cooling measures are taken, and the LED lamps can be prevented from being burnt due to overheating.

Description

Technical field [0001] The present invention relates to the field of LED cooling techniques, and is specifically an over-temperature protection device for parallel LED lamps. Background technique [0002] The light emitting diode is simply referred to as LED. It is made of a compound containing gallium gallium (Ga), arsenic (AS), phosphorus (P), nitrogen (N). Visible light can be radiated when electrons are composite to holes, and thus can be used to make light-emitting diodes. As an indicator light in the circuit and instrument, or make a text or digital display. The arsenide diode is red light, the gallium biological diode is green, the silicon carbide diode is yellow, and the gallium nitride diode is blue. Ballimulated two-active diode OLED and inorganic light emitting diode LEDs. [0003] When the existing LED lamp group is in use, since the LED lamp is lowered, it is necessary to use a cooling device, but the existing cooling device is all uniformly cooling, and it is diffic...

AI Technical Summary

Problems solved by technology

[0003] When the existing LED lamps are in use, the brightness of the LED lamps will decrease when the temperature rises, so it is necessary to use a cooling device. However, the existing cooling devices are all comprehensive and uniform cooling. When the local heating is too fast, it is difficult to cool the area in time. As a result, local lighting brightness is insufficient, and it is difficult to avoid overheating and burning of LED lights
