  • Patent number: 11879622
    Abstract: A driver for driving a light engine of a luminaire is provided. The driver comprises a driver assembly with a driver circuit for converting an input current provided by a power supply into an output current for driving the light engine, a housing for receiving the driver assembly, and a driver interface being detachably engageable with a driver bracket. The driver interface comprises a mechanical interface for mechanically coupling the driver to a mechanical interface of the driver bracket and an electrical interface for electrically coupling the driver to an electrical interface of the driver bracket in such a way that the input current from the power supply to the driver circuit and the output current from the driver circuit to the light engine can flow via the driver interface. Further, a driver bracket and a luminaire are provided.

  • Patent number: 8845173
    Abstract: Disclosed are a static-free light guide plate and a backlight module. The static-free light guide plate comprises an incident plane, a bottom reflection plane, a side reflection plane and an out light plane. At least one layer of optical thin film material for increasing out light effect is positioned on the surface of the out light plane. The bottom reflection plane is positioned on the metal back plate. The static-free light guide plate further comprises interconnected conductive bands positioned at the side plane of the optical thin film material, non-incident portion of the incident plane, the bottom surface of the bottom reflection plane and the side reflection plane. With the conductive bands positioned at the side surface of the optical thin film material and connected to the metal back plate, the electrostatic generated on the light guide plate is transferred to achieve the purpose of protecting the electronic device, such as LEDs.

  • Publication number: 20120287606
    Abstract: The present disclosure provides an LED light source assembly which includes an LED chip and a printed circuit board. The LED chip is arranged on the printed circuit board. At least a hole penetrating the printed circuit board is defined in the printed circuit board where the LED chip is arranged. A diameter of a first end of the hole adjacent to the LED chip is smaller than that of a second end of the hole far from the LED chip. An inner wall of the hole is coated with a heat conductive layer. The present disclosure also provides a backlight module and a liquid crystal display device with the LED light source assembly. The LED light source assembly, the backlight module and the liquid crystal display device provided in the present disclosure can improve the heat dissipation efficiency and extend the product life effectively.
