Abstract: A spliced lamp tube is provided, which includes a first lamp tube assembly, a first adaptor assembly, a second lamp tube assembly and a second adaptor assembly. The first lamp tube assembly includes a first lamp head and a first light source board, and one end of the first light source board is connected to the first lamp head. The second lamp tube assembly includes a second lamp head and a second light source board, and one end of the second light source board is connected to the second lamp head. The first lamp tube assembly is connected to the first adaptor assembly and the second lamp tube assembly is connected to the second adaptor assembly. The first adaptor assembly and the second adaptor assembly can be spliced together in order to combine the first lamp tube assembly with the second lamp tube assembly.

Abstract: A manufacturing method for a light board includes step a, covering a light reflection layer on one surface of a galvanized plate; step b, producing a forming space by applying a stamping process along a direction from the light reflection layer to the galvanized plate; and step c, disposing a plurality of light bead bars on the light reflection layer. Accordingly, as one surface of the galvanized plate is covered by the light reflection layer, the application of the light reflection layer at the inner surface of the board increases the light reflection performance of the board so as to improve the whole lighting effect and the illumination performance of the light board. Moreover, as the outer surface of the board is the galvanized plate, the outer surface of the board has the anti-corrosion effect.

Abstract: A lamp device with changeable lamp socket includes a light tube, a light source plate received in the light tube, and two lamp sockets locked with two ends of the light tube. The lamp socket includes a first tubular body, a first covering plate, and two conductive plugs. The lamp device further includes two adapter covers detachably locked on the lamp sockets. Each adapter cover includes a second tubular body, a second covering plate, and a conductive component. For each of the lamp sockets and the corresponding adapter cover, the conductive plugs are inserted into insertion holes of the second covering plate, and the conductive component is electrically connected to the conductive plugs, passes through an opening of the second covering plate, and exposed from the second covering plate.

Abstract: A detachable panel light includes an outer casing, light emitting members, and magnetic members. The outer casing includes a detachable covering plate and holding members respectively at two sides of the detachable covering plate. One surface of the magnetic member is attached on an inner surface of a receiving groove of the outer casing, and one surface of the magnetic member is attached on the corresponding holding member. The light emitting members are assembled on the outer casing. Each of the light emitting members includes a supporting frame assembled on the corresponding holding member, a light source plate assembled on the supporting frame, and a lightshade assembled on the supporting frame to cover the light source plate. Accordingly, the light emitting members are modularized and attached on the outer casing by the magnetic members. Therefore, the maintenance and the replacement for the LED modules can be convenient.

Abstract: A working light includes a frame and a plurality of LED modules located in the frame. Two supporting plates at two ends of the frame are respectively combined with two ratchets. Two ends of the LED modules are combined with ratchet plates. The ratchets are respectively assembled to the ratchet plates to control a rotation angle of the LED modules. The working lights can be stacked with each other in one or more directions. The ratchets are at the side portions of the LED module. Therefore, after the LED module is assembled in the frame of the working light, the ratchets allow the LED module to be rotatable within 180 degrees. Hence, the LED module can be rotated, so that the illumination angle of the LED module is adjustable.
