Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a heat dissipation type patch light emitting diode. Background Art

[0002] A light-emitting diode (LED) is a semiconductor component made from compounds containing gallium, arsenic, phosphorus, and nitrogen. It features low operating voltage, low current, minimal power consumption, long lifespan, and unidirectional conductivity, effectively converting electrical energy into light. LEDs can emit light in a variety of colors, including red, green, and blue, and are widely used in indicator lights, display screens, lighting, and traffic signals.

[0003] The China Patent Network discloses a SMD LED, publication number CN107763451B. While this utilizes a lamp housing as a carrier, transforming a plug-in-only LED into a surface-mountable one, the PIN pins are directly embedded within the lamp housing, forming an integral unit with the housing and less susceptible to deformation and misalignment. However, the patent lacks a heat dissipation structure, resulting in high operating temperatures for the LED, making it susceptible to overheating and malfunction, severely impacting its efficiency and service life.

[0004] Therefore, a heat dissipation type SMD light emitting diode is proposed. Utility Model Content
