Abstract

The invention discloses a double-color-temperature integral LED headlamp with high practicability. The double-color-temperature integral LED headlamp comprises an LED lamp board, a heat conduction post, a copper base plate, a heat radiator, a heat radiation cavity, a high-speed fan, a light shielding cap, a driving control module and a lamp holder, wherein the heat conduction post is fixedly arranged at the left side of the lamp holder; a rectangular installing groove is formed inside the heat conduction post; the heat radiation cavity is formed in the right side of the lamp holder and communicates with the rectangular installing groove formed in the heat conduction post; a solid mosquito repellent agent cabinet is arranged on the outer wall of the heat conduction post; solid mosquito repellent agents are filled in the solid mosquito repellent agent cabinet; when the heat conduction post is heated, the volatilization of the solid mosquito repellent agents filled in the solid mosquito repellent agent cabinet can be accelerated, so that mosquito mosquitoes around the headlamp can be repelled; people around the headlamp are prevented from being bothered by the mosquitoes and insects;and the practicability of the headlamp is improved. The double-color-temperature integral LED headlamp with high practicability has the advantages that the structure is simple; the operation is convenient; the use mode is flexible; the heat radiation effect is good; meanwhile, the manufacturing cost is low; the assembly process is optimized; the product qualification rate is improved; and the popularization and the use are convenient.

Description

technical field [0001] The invention relates to an LED headlight, in particular to a highly practical dual-color temperature integrated LED headlight. Background technique [0002] LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a P-N junction. When electric current acts on this chip by wire time, electron will be pushe...

Problems solved by technology

[0004] Most of the car lights in the existing market use a color temperature of 6000K. In rainy and foggy days, the penetrating power is low, and the lighting distance of the lights is relatively short, and the dual-color temperature LED headlights mainly use two lamp beads with different color temperatures to achieve three modes of dual-color temperature. , that is, a white-lighting lamp bead and a yellow-lighting lamp bead are attached to the circuit board at the same time, and they are separately controlled by the driving circuit to realize three light-emitting modes; this scheme uses two lamp beads, As a result, the cost increases. The lamp bead patching process requires high precision and complicated process, which may easily lead to potential risks such as false soldering, false soldering, and crooked lamp bead sticking. At the same time, due to the simultaneous control of two independent lamp beads, the control and drive scheme is complicated. , which increases the cost of the driving solution and also increases the risk. At the same time, the thickness of the copper substrate used by most of the two-color temperature lamp beads on the market is 1.0mm. The heat emitted by the lamp bead cannot be fully and timely exported, so that the lamp bead light decays, the life is shortened, the lamp bead burns out and other potential risks
