Abstract: A tubular LED light fixture includes a lamp holder; printed circuit board; a plurality of point light sources; lens; strip-shaped convex lens array, located between the lens and printed circuit board and arranged along the length direction of the tubular LED light fixture for converting each point light source into a plurality of consecutive sub point light sources, and the sub point light source converted by the adjacent point light source is connected or overlapped. The invention adopts a strip-shaped convex lens array which forms a line light source only by diffusing light from the point light source only in the length direction of the strip light fixture, preventing light from diffusing in multiple directions, so that the line source is purified. The lens is arranged to perform light distribution in the other direction to the line source, thereby reducing energy attenuation and ensuring the light effect.

Abstract: A tubular lighting device encloses a plurality of LEDs and delivers light with uniformity, resembling the light delivered by a single linear light source. The tubular lighting device comprises a housing, a lighting chassis mounted on the housing, at least one circuit board with a plurality of LEDs mounted on the lighting chassis, each LED having a length A and two adjacent LEDs being separated by a distance L, a thin film mounted on the base and above the plurality of LEDs, the thin film being separated from the plurality of LEDs by a distance H, and a lens mounted on the lighting chassis and above the thin film.

Abstract: An assemble mechanism of LED lamp and a disassembling method, the assemble mechanism of LED lamp includes strip houses, covers, and coupling assembly. The coupling assembly includes a plug, and a socket. The plug includes a plug-body, and a T-shaped head. The T-shaped head includes a straight bar, and a horizontal bar. The straight bar provides two wedge structures on two side walls respectively. The socket includes a socket body, and a T-shaped cavity configured for receiving the T-shaped head. The T-shaped cavity provides two catches on the two inner side walls, the two catches is configured for clamping the two wedge structures. As long as the plug of the coupling assembly is engaged with the socket, and the wedge structure is clamping into the catch, which makes interconnection of the two LED lamps simple and convenient, and helps to reduce the installation time.

Abstract: A LED strip light includes at least one LED chip and a lens device. The lens device includes at least one optical axis, a diffuser plate, a spread-light lens disposed on the diffuser plate and including a plane light incidence surface being perpendicular to the at least one optical axis, and a first convex light emitting surface and a second convex light emitting surface which are positioned at two sides of the at least one optical axis respectively. On a cross section taken along the at least one optical axis, an arc length and a radius of curvature of a profile of the first convex light emitting surface being larger than that of a profile of the second convex light emitting surface, irradiation distance of emergent light of the first convex light emitting surface being less than that of emergent light of the second convex light emitting surface.

Abstract: An LED driver having short circuit protection includes a power, a controlling module coupled to the power and be configured to control output thereof, a sampling module electrically connected to the controlling module, a switch controlling module coupled to the sampling module, and a second switch coupled to the switch controlling module 40 and the output end of the power. The controlling module includes a first switch. The sampling module gets a low level signal during that short circuit is occurred in the first switch. When the switch controlling module receives the low level signal, it turns off the second switch so as to reduce the input voltage of the controlling module. The LED driver having short circuit protection can protect the first switch and load during that short circuit is occurred in the first switch.
