In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0021] This article

[0022] Use of the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 3 As shown, a dual-color temperature LED lamp comprises a heat dissipation component 10 and an LED lamp component 20 installed at one end of the heat dissipation component 10, wherein the LED lamp component 20 comprises a lamp holder 210 and a driving board 220 installed on the lamp holder 210, wherein a lamp board 230 is installed on the driving board 220, and the lamp board 230 is electrically connected to the driving board 220, wherein a plurality of LED lamp beads 231 are installed on the lamp board 230, and the LED lamp beads 231 are divided into warm color lamp beads 2311 and cold color lamp beads 2312, wherein the warm color lamp beads 2311 are electrically connected to a first color temperature chip, and the cold color lamp beads 2312 are electrically connected to a second color temperature chip, and the positions of the warm color lamp beads 2311 and the cold color lamp beads 2312 are staggered with each other, in order to ensure that the light center is at the same horizontal position, so that it can pave the road lighting when switching colors, thereby improving driving safety.

[0024] Furthermore, the heat dissipation assembly 10 includes a heat dissipation housing 110, a heat dissipation fan 120 installed in the heat dissipation housing 110, and a top cover 130 installed at the top of the heat dissipation housing 110, and the heat dissipation fan 120 is electrically connected to the driving board 220. In the present utility model, in order to enhance the heat dissipation effect and better dissipate heat, the heat dissipation housing 110 is further provided with a plurality of heat dissipation fins, and the heat dissipation fins are integrally formed with the heat dissipation housing 110.

[0025] Furthermore, the two ends of the top cover 130 are respectively provided with a first screw hole 131, the two ends of the heat dissipation fan 120 are respectively provided with a second screw hole 121, and the two ends of the heat dissipation housing 110 are respectively provided with a third screw hole, and the first screw hole 131, the second screw hole 121 and the third screw hole are overlapped. During the installation process, the heat dissipation fan 120 is installed in the reserved installation position of the heat dissipation housing 110, and then the top cover 130 is buckled on the top of the heat dissipation housing 110, so that the first screw hole 131, the second screw hole 121 and the third screw hole are overlapped, and they are fixed by bolt connection to enhance the stability of the structure.

[0026] Furthermore, a dimming switch 30 is installed on the heat dissipation housing 110, and the first color temperature chip and the second color temperature chip are respectively arranged at the position of the dimming switch 30, and the color temperature is selected along with the switching of the dimming switch 30. Specifically, when the white light (i.e., the cold color lamp bead 2312) is turned on, when the color temperature needs to be switched, the power is turned off for 2 seconds, and the switch is switched continuously to achieve the color temperature switching; similarly, when the yellow light (i.e., the warm color lamp bead 2311) is turned on, when the color temperature needs to be switched, the power is turned off for 2 seconds, and the switch is switched continuously to achieve the color temperature switching.

[0027] Furthermore, the car lamp also has a memory function. According to the user's operating habits, the color temperature of the light can be the same as before the power failure when it is turned off and then restarted, and the color temperature remains unchanged. In addition, the utility model also has a reset function. Specifically, when the white light (i.e., the cold-colored lamp bead 2312) is turned on and needs to be reset, after the power is turned off for 2 seconds, the switch is switched twice in succession within 2 seconds, and the switch is turned on for the third time to reset to the white light.

[0028] Furthermore, a boss 111 extending downward is provided at the bottom end of the heat dissipation housing 110, and the boss 111 passes through the lamp holder 210 and is connected and fixed to the lamp holder 210, wherein a first mounting hole 1111 is provided on the boss 111, and a second mounting hole 221 that overlaps with the first mounting hole 1111 is provided on the driving board 220. In the present utility model, when the boss 111 passes through the lamp holder 210, the driving board 220 is installed in the lamp holder 210, and the first mounting hole 1111 and the second mounting hole 221 overlap, and then the lamp holder 210 is fixed by bolts.

[0029] In addition, in order to enhance the stability of the structure, the vehicle lamp further includes a rubber ring 40 , and the rubber ring 40 is sleeved on the outer circumference of the lamp holder 210 .

[0030] The above-mentioned dual-color temperature LED car light can quickly switch the color temperature according to the needs of different usage scenarios through reasonable settings, which is convenient for road lighting. At the same time, the car light also has memory function and reset function, which greatly enhances the user experience. In addition, the utility model has a simple structure, beautiful appearance, and can meet the needs of users.
