Abstract: A lamp tube and a lamp fixture with sensing capability are disclosed. The lamp tube with sensing capability includes a lamp tube body, and the lamp tube body includes a power converting unit, an LED strip and a sensing unit. The power converting unit is for receiving AC power and outputting DC power for driving the LED strip and the sensing unit. The sensing unit will timely output a fire alarm signal to notify the firemen and the people nearby when a fire occurs. The shape of the lamp tube with sensing capability is the same as a normal lamp tube, so both of them can be installed in the same lamp fixture. One normal lamp tube is replaced by the lamp tube with sensing capability to include a fire sensing function. The safety is enhanced and the installation is convenient.

Abstract: An LED tube has a tube body, an LED light board and two caps. The tube body has a translucent tube shell and a heat dissipating seat. The translucent tube shell has two openings and a gap. The heat dissipating seat is mounted in the gap. The LED board faces toward the translucent tube shell and has a convex luminous surface obliquely facing toward the translucent tube shell to increase an illumination range of the LED light board, thus, an illumination angle of the LED tube in accordance with the present invention is also increased. Therefore, the LED tube glows evenly and eliminates grain effects of the LED tube.

Abstract: The present invention is a circuit board connector, and the circuit board connector comprises an insulative block and at least one electric connecting bar. The insulative block has a supporting surface. The at least one electric connecting bar is mounted through the insulative block, and each electrical connecting bar has two terminals bent to the supporting surface. Each of the terminals has a bending part and a welding part, and the welding part is close to the supporting surface. When two circuit boards are connected, the welding parts of the terminals of the electric connecting bar are welded with bond pads of each of the circuit boards to electronically connect the circuit boards, and the insulative block is connected to the circuit boards to fix the circuit boards. Therefore, the circuit boards can be fixed and electronically connected for forming a large circuit board.

Abstract: A light-emitting diode (LED) tube has a tube and at least one LED tube fastener. Each of the at least one LED tube fastener has a body and a magnetic core. The body has at least one insertion leg formed on a bottom thereof and connected to a top wall of the tube. The magnetic core is mounted in a top portion of the body to be magnetically attached to a lamp fixture when the LED tube is mounted on the lamp fixture such that the at least one LED tube fastener holds and supports the LED tube and the LED tube is not bent due to a weight thereof.

Abstract: An LED tube has a tube body, an LED light board and two caps. The tube body has a translucent tube shell and a heat dissipating seat. The translucent tube shell has two openings and a gap. The heat dissipating seat is mounted in the gap. The LED light board is mounted in the tube body and has a luminous surface, wherein two opposite ends of the LED light board extend out of the heat dissipating seat. The luminous surface has four electrical connecting parts, wherein each two electrical connecting parts are respectively mounted near a corresponding one of the two opposite ends, thus, the four electrical connecting parts are mounted away from the heat dissipating seat to extend internal creepage distances between the four electrical connecting parts and the heat dissipating seat, and further increase electrical safety of the LED tube.

Abstract: An LED tube has a tube body, an LED light board and two caps. The tube body has a translucent tube shell and a heat dissipating seat. The translucent tube shell has two openings, a gap, two side walls separated by the gap, two first slide tracks and two second slide tracks. The heat dissipating seat is mounted in the gap and has two opposite sides respectively mounted in the two first slide tracks. The LED board abuts the heat dissipating seat and has two opposite sides respectively mounted in the two second slide tracks. The sides of the heat dissipating seat and the sides of the LED light board are separated by the first and the second slide tracks to extend creepage distances between the heat dissipating seat and the LED light board, and further avoid a short circuit between the heat dissipating seat and the LED light board.
