A lamp includes a first body and a second body. The first body has a protrusion, a first engaging portion and two ribs. The second body has a second engaging portion which is engaged with the first engaging portion. The second engaging portion has two L-shaped connection slots with which the ribs are engaged.

The second body has a first guide path and three second guide path. Two inclined ramps are located in the first guide path so that the protrusion of the first body slides along the inclined ramps to guide the first engaging portion to be engaged with the second engaging portion. The protrusion is restricted by the contact faces of the blocks to restrict that the second body can only be rotated in one direction to engage the ribs with the connection slots.

The multiple functions wall cover plate has built-in USB and light means connect by prong means to existing wall inner-kit's receptacle to get AC power source to multiple function wall cover's circuit(s) to drive each circuit for predetermined functions. The said cover plate fasten by screw, prong or false prong to hold on inner-kit's holder and overlay at least one of the inner receptacle to offer people safety and quickly USB charger with desire light illumination and add extra functions.

A partition wall usable in any residential or work environment is described having modules that can be customized to create a partition wall that best suits the needs of the user. The modules that make up the partition wall can be made from a single frame structure or multiple frame components that connect together to form generally rectangular or square like modules or building blocks that form the partition wall. The modules can connect to any adjacent module on each side or top or bottom. The modules are assembled into the requisite number of rows and columns to form the partition wall at the desired width and height. The modules include electrical contacts to provide electrical power to one or more add on pieces that require power to function, including, fans and light panels. Further, sound batting can be added, and decorative panels to provide an aesthetically pleasing appearance.

Systems, devices, and methods for a decorative outdoor light fixture that can include an adjustable motion sensor with a rectangular coverage pattern. An adjustable motion sensor for a light fixture can include an outer housing connected to a light fixture frame, a movable sensor assembly including a motion detector contained within the outer housing, a lens covering a portion of the outer housing in the path of the motion detector sensing beams to direct the sensing beams in a rectangular coverage pattern, and a sensor adjustment mechanism accessible from an exterior of the outer housing to allow a user to rotate the sensor adjustment mechanism to cause the motion detector to move upward and downward. The adjustable motion sensor covered with a fixed window that hides the motion sensor assembly from view.

A wall- or surface-mounted light fixture with a housing containing one or more external visible light sources to illuminate the space where the light fixture is mounted, one or more UV emitters inside the housing to destroy bacteria and pathogens, and one or more fans inside the housing that recirculate the air in a space and subject the air to the UV radiation inside the housing, destroying bacteria and pathogens in the air passing though the housing.

According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, an LED mounted to the circuit board that is configured to emit light with an angular CCT deviation, a lens assembly mounted to the circuit board over the LED and configured to receive the light emitted from the LED and reduce the angular CCT deviation of the light received from the LED to make a color temperature of the light received from the LED more uniform, and an elastomer encapsulating at least part of the circuit board that is separate and distinct from the lens assembly.

A lighting unit body comprises: a light source; and shaped-members, in which a housing portion in which the light source is disposed, reflective surfaces for reflecting light from the light source, and an emission outlet for emitting the light from the reflective surfaces are respectively formed in the longitudinal direction. When a position at which the emission outlet is disposed is defined as forward and a direction orthogonal to the longitudinal direction is defined as a front-to-rear direction, and a direction orthogonal both to the longitudinal direction and the front-to-rear direction is defined as a left-to-right direction, then the emission outlet is formed in a front portion of the reflective surfaces, and the housing portion is formed in a rear portion of the reflective surfaces directed obliquely rearward at a predefined inclined angle on one of left or right side. The predefined inclined angle is an angle that inhibits visual observation of the light source from the front of the emission outlet, and the left-to-right direction position at which the light source is disposed is included in the left-to-right direction position at which the emission outlet is located.

An emergency lighting unit includes a housing. The housing includes a base having a first portion and a second portion. A lamp assembly is rotatably connected to the housing and positioned in the lower portion. A cover is provided over the lamp assembly.

An apparatus includes a power adapter, a security camera and a base. The power adapter may be configured to receive an AC power source, pass through the AC power source to a light bulb and generate DC power by converting the AC power source. The security camera may be configured to receive the DC power from the power adapter. The security camera may comprise a camera module. The base may comprise an opening for a light fixture and an attachment location. The power adapter may be electrically connected to the attachment location. The power adapter may receive the AC power source from an electrical connection for the light fixture. The security camera may be configured to receive the DC power from the power adapter. The security camera may be removably attached to the attachment location. The camera module may be located beyond a front face of the light fixture.

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.
