A lighting device including: a source emitting a light cone; an electronic control circuit; a wall defining an enclosure including a first area through which the light cone passes, and a second area complementary to the first area; and a diffuser directing part of the light by backscattering towards the second area. The diffuser includes a first part oriented perpendicular to the axis of revolution of the light cone and forming a first divergent lens, and a second part forming a second divergent lens having a shape of a flared truncated cone with its axis of revolution parallel to the axis of revolution of the light cone, in which a larger diameter end is closest to the light source and a smaller diameter end is adjacent to the first part and surrounds the first part.

It is an object of the present invention to provide a small and simply-structured light-source device. A light-source device according to the present invention includes a laser light source section, a stem on which the laser light source section is mounted, a cap with an opening, the cap being bonded to the stem in such a manner that the cap covers the laser light source section, a lens holder joined to an outer surface of the cap in such a manner that the lens holder extends over the opening, and a collimating lens supported by the lens holder, the collimating lens collimating a light ray emitted from the laser light source section and then passing through the opening.

In the soil cultivation system equipped with a solar panel, the space between ridges of a plurality of frame units supporting the solar panels is coupled with a roof member, furthermore, the perimeter surface thereof is integrally covered with a cover unit. In this way, a cultivation house in which the frame units are used as support columns is established. Then, in the solar panels, light transmitting regions are provided, a transmissive member is used as the roof member and thus agricultural plants are cultivated by light passing through the light transmitting regions and the roof member. Furthermore, the cultivation of the agricultural plants is performed in cultivation tanks in which a soil is put, and an appropriate cultivation nutrient solution is supplied through a supply means. In this way, the cultivation environment of the agricultural plants is managed, and thus the agricultural plants can be efficiently cultivated while the burden of an operator is reduced.

A table that includes a planar upper surface having a recess, a lamp positioned in the recess, a first sensor, and an embedded touch control. The lamp can be in a closed position or a raised position, and have a first section and a second section. The first section is attached to the planar upper surface at an end thereof. The first sensor detects the position of the lamp and controls the lamp based on the position of the lamp. The embedded touch control is located beneath the planar upper surface, and controls the light level of the lamp.

A panel light apparatus includes a base plate, a light source, a frame and a light passing cover. The base plate has a fixing unit for fixing the base plate to a platform. The base plate has multiple rotation units to switch between a lock mode and a release mode. The light source is disposed on the base plate. The frame has multiple attaching units to attach to the rotation units in the lock mode for fixing the frame to the base plate. The multiple attaching units are released from the rotation units in the release mode. The frame has a light opening. The light passing cover attached to the frame for covering the light opening for a light of the light source to pass through.

A sconce box assembly for mounting sconces on walls of various wallboard thicknesses and shallow wall cavities with no disruption to the surrounding wall. The sconce box assembly includes an electrical box having a sidewall, a back wall, an electrical cavity, and wing bosses extending from the sidewall. First rotatable wings secured to the wing bosses are adapted for rotation between a retracted position, in which the rotatable wings are positioned inside the sidewall perimeter, and an extended position in which the rotatable wings are positioned outside the sidewall perimeter. Retracting the wings facilitates insertion of the electrical box through a hole in a wall. Extending the wings facilitates tightening the wings and clamping the electrical box to the wallboard. The invention contemplates at least one second rotatable wing that may be used optionally in place of the first rotatable wing in order to accommodate attachment to various thicknesses of wallboards.

A lighting device includes a housing including a hole; a light source body including a light emitting module with a terminal; and electrical connection means including a portion projecting through the hole and having a connector electrically connected to the terminal and physically connecting the housing with the light source body.

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 light fixture includes a light receiver, an electrically-powered light source coupled to the light receiver, and a vessel containing a liquid. The vessel is translucent such that the light from the light source radiates through the vessel. The vessel includes an outer wall and an inner wall that define an enclosed area that receives and contains the liquid. The inner wall defines an open area positioned radially inward from the enclosed area and the inner wall includes a top opening and a bottom opening such that the open area is a through-hole extending through the enclosed area. The vessel is configured such that light emitted from the light source passes through the liquid contained within the vessel.

A phosphor sheet includes: a stacked structure including a first phosphor layer and a pair of transparent films each being in contact with either side of the first phosphor layer; a seal layer integrally covering an area from an end face of the stacked structure to a periphery of the stacked structure; and a second phosphor layer further covering a portion of the seal layer, the portion covering at least the periphery of the stacked structure.
