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 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.

The present disclosure relates to an LED explosion-proof lamp. The LED explosion-proof lamp includes a lighting portion having a first engagement structure and a first positioning hole, a connecting portion detachably connected to the lighting portion and having a second engagement structure, a second positioning hole, and an opening suitable for accommodating the support rod of the LED explosion-proof lamp, a positioning member detachably inserted into the first positioning hole and the second positioning hole, wherein one of the first engagement structure and the second engagement structure is configured as a sliding groove, and the other of the first engagement structure and the second engagement structure is configured as a protrusion adapted to be inserted into the sliding groove and movable along the sliding groove. The LED explosion-proof lamp has the advantages of simple structure, easy processing and assembly, and high structural strength.

A modular lighting assembly uses LED banks as the light sources. The assembly allows the power supply and LED banks to be independently replaced. The assembly uses a power supply that is separated from the LED banks and electrically connected to the LED banks with a plug connector that may be unplugged and plugged back in to allow the power supply or LED bank to be independently and readily replaced. The assembly provides for easy replacement of the different components of the assembly. One feature that makes the components easier to replace is that the light modules and/or the power supply may be carried by the housing that is removable from the base mount that is secured to a mounting structure such as a wall or ceiling.

The present disclosures provides a collar for positioning at least partially around a recessed light fitting and between the recessed light fitting and a structural body. The collar comprises a plurality of collar portions each of which are configured to surround a portion of the recessed light fitting.

A panel lamp includes a bottom case, a lamp cover, a lighting assembly arranged between the bottom case and the lamp cover, at least two bendable suspending assemblies arranged at two opposite sides of the bottom case. The bottom case defines a mounting groove, and an edge of the lamp cover is configured to be received into the mounting groove. The suspending assemblies are configured to hang the bottom case onto an overhead structure.

The present disclosure relates to a portable solid-state drive (SSD) module. The portable SSD module includes a case, an SSD, a light-emitting device (LED) module and a main bracket. The case may have a window. The SSD may be arranged in the case. The LED module may be arranged in the case to indicate an operation of the SSD through the window. The main bracket may be arranged in the case to support the LED module. Therefore, the LED module may be readily and firmly combined with the case.

A recessed light and a lampshade thereof are provided. The lampshade includes: a shade body, including a cover member and a top plate covered on the cover member, the top plate including a notch, the notch being open at a periphery of the top plate, the shade body further including a slot, the slot being in communication with the notch, the slot having a width larger than a width of the notch, the diametric dimension of the flange being larger than the width of the notch; wherein the slot is configured to receive the flange, the notch is configured to receive the body portion, and the top plate is configured to be engaged between the substrate and the flange.

An optical device includes first and second optical elements rotatable with respect to each other around a geometric optical axis of the optical device. The first optical element includes a first surface for modifying a distribution of light exiting the first optical element, and the second optical element includes a second surface facing towards the first surface and for further modifying the distribution of the light. One of the first and second surfaces includes convex areas whereas the other one of these surfaces includes concave areas so that an optical effect of the optical device is changeable by rotating the first and second optical elements with respect to each other. The first and second optical elements include sliding surfaces for mechanically supporting the second optical element with respect to first optical element in radial directions perpendicular to the geometric optical axis.
