Abstract:
The LED lighting device includes a tubular housing, a light emitting unit, and a reflector. The tubular housing has an accommodating space. The light emitting unit is disposed in the accommodating space and has a plurality of light emitting diodes. The reflector is disposed in the accommodating space and has a wing-shaped reflecting portion. The reflecting portion faces the light emitting unit for reflecting the light source emitted from the light emitting diodes to the lateral directions of the tubular housing. As a result, the light source can be converted to a specific direction. Compare to the fluorescent lamps, the present invention has higher illumination efficiency and a longer operating life. The volume of the lamps and the cost are saved.
Abstract:
An assembly of a lighting unit and a receptacle unit includes at least one receptacle unit and at least one lighting unit. The receptacle unit has an outer housing provided with at least one first connection portion and at least one second connection portion electrically connected to the first connection portion in the outer housing. The lighting unit is electrically connected to one of the first and second connection portions of the receptacle unit, so that the lighting unit and the receptacle unit can be independently rotated in relation to each other along a connection axis thereof.
Abstract:
An array type light-emitting module includes a blue, a red, a green, a yellow and an amber light-emitting chip sets. Wavelength-converting layer set covers the blue light-emitting chip set. Transparent layer sets cover the red, green, yellow, and amber light-emitting chip sets. A portion of the visible light emitted by the blue light-emitting chip set is converted into visible light with another emission peak wavelength range via the wavelength-converting layer set. The converted visible light mixes with light projected from the red, the green, the yellow and the amber light-emitting chip sets to generate white light with a color rendering index ranging between 90 and 96.

Abstract:
A LED lamp tube is disclosed to include a tube that admits light, circuit boards respectively mounted inside the tube, each circuit board carrying an array of LEDs, two end caps respectively capped on the ends of the tube to hold the circuit boards inside the tube and connectable to connectors of a conventional fluorescent bulb holder to secure the tube to the conventional fluorescent bulb holder, and a power cord extending from the circuit boards out of the tube for connection to power supply to obtain the necessary working voltage for the LEDs.
Abstract:
A ceramic light emitted diode (LED) package has a pair of discrete reflection walls to reflect light emission from the LED. With two opposite reflection walls and two opposite openings around the LED, light emitted from the LED package can be fanned out.
Abstract:
A LED lamp tube connectable to a conventional lamp holder is disclosed to include a circuit board, multiple arrays of LEDs (light emitting diodes) installed in the circuit board, an outer tubular shell that accommodates the circuit board and the LEDs, and two electric connectors provided at the two ends of the circuit board and extending out of the tubular shell for connecting the circuit board to respective connecting holes at a conventional lamp holder to obtain the necessary working voltage.
