NOVELTY - A vehicle-mounted LED high-brightness backlight source comprises a high-heat dissipation backlight plate, a reflective film, and an LED lamp. The LED lamp is fixedly connected to the high-heat dissipation backlight plate in a dot matrix. The metal heat conducting plate is integrally formed at the bottom of the LED lamp. The metal heat-conducting plate is fixedly connected with an insulating and high-heat-conducting adhesive layer. The surface of the insulating and high-heat-conducting adhesive layer facing away from the metal thermal plate is fixedly connected to the upper surface of the high heat dissipation backlight plate. The reflective film is fixedly connected to the upper surface of the high heat dissipation backlight plate. The reflective film is integrally formed with an installation area for the LED lamp to be fixedly connected to the high-heat dissipation backlight plate. USE - Vehicle-mounted LED high-brightness backlight source used in LCD display product for industrial device, banking terminal, office automation, communication and electronic toy. ADVANTAGE - The vehicle-mounted LED high-brightness backlight source has excellent radiating performance, suppressed backlight plate local heat accumulation, and improved reliability and durability. The insulating high-heat conducting adhesive layer has improved heat conduction efficiency between the LED lamp and the high-heat dissipation backlight plates, and improves reliability, stability, and durability of LED. The heat energy generated by the LED lamps is quickly conducted to the high-radiating backlight plate, and the heat is released to the environment by the high radiating backlight.
