摘要:
A light-emitting diode (LED) street lamp is applicable for street lighting. The LED street lamp includes a casing, an LED module, and a heat dissipation module. The LED module and the heat dissipation module are arranged inside the casing. The LED module includes a frame, a circuit board carrying a plurality of LEDs, and a light regulation mechanism. The frame and the circuit board are set opposing each other with the light regulation mechanism arranged therebetween to interfere with emission light from the LEDs. The emission light, after being interfered with, is projected outside the casing to realize lighting. The heat dissipation module is in physical engagement with the LED module to remove heat generated by the LEDs. As such, the LED street lamp is provided with a broader range of illumination angle and more uniform brightness, so that the same LED street lamp is applicable to various sites and the heat generated by the LEDs can be efficiently dissipated.

A multi-domain vertical alignment liquid crystal display (MVA-LCD) panel including an active device array substrate, a color filter substrate and a liquid crystal layer is provided. The active device array substrate has pixel units. Moreover, the color filter substrate includes a substrate and color filter units. The color filter units are disposed on the substrate. Additionally, the liquid crystal layer is disposed between the active device array substrate and the color filter substrate. The liquid crystal layer above each of the pixel units has domain sets of different alignments.

The present invention provides a glass substrate stacking structure, a glass substrate stacking device, and a method for forming the glass substrate stacking structure, which are particularly suitable for a film coating process to a glass substrate of a TFT-LCD panel. The glass substrate stacking structure includes a first glass substrate and a second glass substrate. The second glass substrate is disposed under the first glass substrate and has air holes. By pumping and blowing air through the air holes, the first glass substrate and the second glass substrate can be adhered to and separated from each other. The present invention also provides a method and a device for stacking the glass substrate stacking structure mentioned above.
摘要:
A light-emitting diode (LED) lamp and a polygonal heat-dissipation structure thereof are provided. The LED lamp includes a polygonal heat-dissipation unit and a lighting module. The polygonal heat-dissipation unit has a polygonal hollow column and fins. The fins and the lighting module are thermally disposed on an inner surface and an outer surface of the polygonal hollow column, respectively. Thus, heat generated by the lighting module is dissipated by the fins rapidly. As the fins are thermally disposed on the inner surface of the polygon hollow column instead of being exposed, the volume of the LED lamp can be minimized, and the look of the LED lamp also can be prettified.
