Abstract: The present invention provides a clock buffer, wherein the clock buffer receives an input signal at a first node and generate an output signal at a second node. The clock buffer includes a P-type transistor, a first N-type transistor, a resistor, a transistor and a switch. A source electrode, a gate electrode and a drain electrode of the P-type transistor are coupled to a supply voltage, the first node, and the second node, respectively. A gate electrode, a drain electrode and a source electrode of the first N-type transistor are coupled to the first node, the second node and a third node, respectively. The resistor is coupled between the first node and the second node. The transistor is coupled between the first N-type transistor and a ground voltage. The switch is configured to selectively connect the third node to the ground voltage.

Abstract: The table lamp contains a lamp base and an extension tube plugged vertically into the lamp base. A curved transparent light tube is attached along its entire length to a parallel and also curved back cover. The combination is joined to a top end of the extension tube. Two light generation assemblies are provided at the two ends of the light tube, respectively, each sequentially composed of a lens, a lens ring, a light emitting diode, a power circuit, a heat dissipation plate, and a heat dissipation element. The light from the light emitting diodes is projected into the light tube and, with a reflection layer along the inner wall of the light tube, the light is uniformly reflected towards the area beneath the table lamp.

Abstract: The tubular lamp device contains a passive and transparent lamp tube whose two ends are plugged into a pair of socket members, respectively. The lamp tube has an axial strip along the circumference coated with a reflective film. The socket member contains a tubular element which receives an end of the lamp tube. Inside the tubular element, a LED element is housed in a hole of a solid lens element which directs the light beams of the LED element towards the lamp tube. The light beams are then reflected by the reflective film to create a large area of illumination as the light beams propagate through the lamp tube.
