Description

Technical Field

[0001] This utility model relates to the field of LED technology, and in particular to a hybrid light source surface-mount LED. Background Technology

[0002] LEDs, as semiconductor electronic components that can convert electrical energy into light energy, have many advantages such as long service life, fast response, small size, light weight, impact resistance, environmental friendliness, easy dimming and color adjustment with high controllability, and low power consumption, making them widely used in lighting, display and many other fields.

[0003] A typical hybrid light source surface-mount LED consists of a mounting structure, an operating structure, and a heat dissipation structure. The mounting structure uses a bracket to fix the LED chip and circuit board inside the protective frame, so that the chip can be stably installed on the target device. After the chip in the operating structure is powered on, it realizes the mixed output of light of different wavelengths, thereby emitting light of a predetermined color. The heat dissipation structure uses a metal substrate to quickly conduct and dissipate the heat generated by the chip operation, preventing the chip from degrading due to excessive temperature.

[0004] In existing technologies, surface-mount LEDs are widely used due to their advantages such as small size, low power consumption, and fast response speed. However, in surface-mount LED devices, the light source chip generates a lot of heat during continuous operation. Due to low heat dissipation efficiency, the heat cannot be dissipated in time, causing the chip temperature to rise sharply. When the chip temperature exceeds its normal operating temperature range, it will cause the bandgap of the semiconductor material to narrow, which will lead to a decrease in luminous efficiency and an increase in light decay, resulting in a significant decrease in the luminous performance of the LED. Unstable temperature fluctuations will cause changes in the photoelectric parameters of the LED, affecting its working stability and failing to meet the requirements of high-reliability lighting and display scenarios. To address these issues, a hybrid light source surface-mount LED is proposed. Utility Model Content
