  • Patent number: 10197262
    Abstract: Disclosed is an LED lighting apparatus having a natural convection-type heat dissipation structure. The LED lighting apparatus includes a heat sink coupled to a back surface of a printed circuit board (PCB) to which a plurality of light emitting diode (LED) devices is mounted and, and functioning to absorb heat generated by the LED devices, in which center portions of the heat sink and the PCB are provided with openings serving as a convection hole that induces natural convection such that hot air under the heat sink rises along with rising hot air attributed to heat radiated from an upper surface of the heat sink and surrounding cooler air is supplied to the upper surface the heat sink and to around the LED devices. Due to the convection hole, the LED lighting apparatus provides a heat dissipation effect as high as that of an active cooling system.

  • Patent number: 10185077
    Abstract: The disclosure provides a LED light bar configured in a backlight module, including a light bar circuit board and LEDs disposed on the light bar circuit board. A long side of the light bar circuit board is defined with a nick. The nick forms a first embedding section. A heat dissipation section is disposed in the first embedding section. The disclosure further provides a backlight module, including a light guide plate disposed in a frame, further including the LED light bar configured in a backlight module. Compared with the prior art, the heat dissipation section is disposed on the light bar circuit board to conduct heat of the LEDs out of the backlight module, which reduces the heat in the center of the LED light bar and improves heat dissipation of the backlight module, further preventing the optical films from being wrinkle and dark regions appearing in the backlight module.
