Description

technical field [0001] The invention relates to the technical field of LED heat dissipation, in particular to a high heat dissipation two-color LED vehicle lamp. Background technique [0002] High-quality car light source is the guarantee for our night driving road. Therefore, the pursuit of better light source has become the common goal of car owners and manufacturers. LED has gradually replaced traditional halogen lamps and LED car lights due to its own advantages. Good monochromaticity, good shock resistance, high efficiency, low energy consumption, small size, light weight, more focused illumination effect, easy installation, and effectively improve road lighting to ensure driving safety. However, most of the current market lights are Monochrome lights, headlights, fog lights, turn signals, reversing lights, etc. are all separate monochrome lights, which require a separate set of lamp bodies and heat sinks, which increases production costs. In order to improve the integr...

Problems solved by technology

[0003] In the utility model patent document with the authorized notification number CN206817335U, a new type of two-color LED car lamp is disclosed, including an LED bulb and a controller. The LED bulb includes a hollow cylindrical cylinder and a heat sink. The middle part of the cylinder is A rectangular cross cut is provided, and a hollow trumpet-shaped heat transfer chamber is arranged behind the cross cut, a heat transfer conductor is arranged in the heat transfer chamber, an LED light source board is arranged in the cross cut, and the The LED light source board is provided with a first LED white light-emitting diode and a second LED yellow light-emitting diode. Conductor connection, the open end of the heat transfer chamber is connected to the heat sink, the LED light source board is connected to the controller through a power cord, and a power cord plug is provided at the tail of the power cord. Design, users can choose LED light emitters of different colors to emit light according to the application needs of different time periods and environments. It has a wider range of use, is convenient to install, and is easy to disassemble and replace. It saves costs and saves space. However, due to the use of two-color LED lights The increase in the number of LED lamp beads will generate more heat energy. If the heat is not dissipated in time, the service life of the LED car light will be greatly reduced, electronic failures will occur, and electronic components or lamps will be damaged. The structure of the two-color LED car light only passes through the heat transfer chamber. There is a heat transfer conductor inside, and then the heat transfer conductor is connected to the heat sink to conduct the heat on the LED light source board to the heat sink for heat dissipation. However, this structure only realizes heat dissipation through the heat transfer function of the heat transfer conductor. The existing One way to realize the heat transfer conductor is to use a heat transfer medium for active heat conduction, but it requires a complex structure and high cost, which is not conducive to the miniaturization of LED lights. Another way to realize the existing heat transfer conductor is to use metal Conduction through the body, but it is mainly passive heat transfer. If the air circulation in the space where the heat transfer conductor is located is poor, the heat cannot be transferred to the radiator in time, thus limiting the heat dissipation performance and efficiency of the LED.
