An LED tube lamp comprises a glass lamp tube having a main body, two end caps coupled to a respective end of the tube, an LED light strip adhered to inner circumferential surface of the tube by first adhesive, a plurality of LED light sources mounted on a mounting region, a power supply module having a circuit board and a plurality of electronic components mounted on the circuit board, a diffusion layer covering on outer surface or inner surface of the tube, and a protective layer being disposed on surface of the strip and having a plurality of first openings for disposing the plurality of LED light sources. The strip comprises the mounting region and connecting region at an end of the strip. The circuit board is substantially parallel with axial direction of the tube, electrically connects to the connecting region, and stacks with a portion of the connecting region.

A strip lamp includes a body, a lampshade, an illuminating component and a holder. The body includes a support wall and a tilt wall. The tilt wall is connected to the support wall's two opposite lateral sides. Also, the tilt wall forms an included angle between the tilt wall's two opposite lateral sides. The lampshade is detachably engaged with the body and is detachably connected to the tilt wall's both lateral sides. The illuminating component is installed on the support wall to face against the lampshade's inner surface. The illuminating component's illuminating span angle is smaller than or equal to the tilt wall's included angle. The holder is detachably engaged with the body. In addition, the holder loads the illuminating component.

A channel system that includes a first channel section, a second channel section, and a hinge joint between the first and second channel sections is disclosed. The hinge joint allows the first channel section to fold against the second channel section for storage and shipping of the channel system. In one embodiment, the hinge joint itself includes a hinge member that extends between the two channel sections and bends hingedly to allow movement and two intermediate endcaps, which cap the channel sections on either side of the hinge joint. The hinge joint may be designed to “snap back” to a fully extended position. Mechanical securement structure may be added to the first channel section and the second channel section to improve force and retention during the “snap back” movement.

A high-durability tri-proof lamp with color temperature adjustment function is provided, which includes a lamp housing, a movable support plate, a circuit board and a driving power source. The lamp housing has two connection holes and a guiding groove. The lamp housing is hollow and has a chamber; the connection holes are disposed at the two ends of the lamp housing. The guiding groove includes two lateral guiding slots disposed at the two sides of the chamber. The movable support plate is disposed in the chamber. One side of the movable support plate and the other side thereof are inserted into the lateral guiding slots, such that the movable support plate is able to move along the guiding groove. The circuit board is disposed in the chamber and connected to the movable support plate. The driving power source is disposed on and electrically connected to the circuit board.
