Abstract: An LED lighting device includes a light pipe and a support portion. The light pipe includes a light emitting diode module inside and two first fastening portions on an outer wall thereof. A support portion secures the light pipe and provides a rotatable function for the light pipe. The support portion further includes a clamp and a base member. A clamp has two second fastening portions at opposite sides thereof. The second fastening portions engage with the first fastening portions. The clamp further includes a strip hollow slot. A base member includes a pair of positioning portions for holding an outer wall of the clamp, wherein a fastener is led through the strip hollow slot and fastened on the base member. The clamp slides relative to the base member along the strip hollow slot such that the light pipe rotates relative to the base member.

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 male terminal cap and a female terminal cap are mounted on the two ends of a strip light shade to form an extensible strip light shade. Electrical contacts are formed in the terminal caps for electrical coupling when two light shades are connected through mechanical coupling of the terminal caps.

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 Lamp module, which includes a metal holder frame that defines a longitudinal open chamber and transverse mounting slots across the longitudinal open chamber, LEDs that are respectively mounted in the transverse mounting slots and have a respective top metal frame fastened to the top wall of the metal holder frame for quick dissipation of heat, light guides mounted in the longitudinal open chamber of the holder frame and respectively perpendicularly attached to the LEDs, and reflectors respectively embedded in the light guides for reflecting light in one direction.

Abstract: An LED module is disclosed to include a light guide tube, two LEDs provided at the two ends of the light guide tube, a reflector strip, which has an arched reflecting surface for reflecting light from the LEDs, and a converter for converting input power supply to the desired working voltage level for the LEDs.

Abstract: A structural improvement of a LED. It constructed a third leg between the first and second leg. A chip resistor is stick between the third leg and the first leg by using electric conducting resin, also a LED dice is placed on the top of the third leg, and it is connected with the first leg by using wire. The above description can be sealed in a gum body and be produced by machine. This would decrease the budget and achieve the goal of not enlarging the LED.
