The lighting unit has at least one device (23; 23; 23) on a rear side (19; 19; 19; 119; 119) facing away from the light output side (17; 17; 17; 117; 117); 123; 123) which can be used to attach the lighting unit in a selectable location on the rear wall (13; 13; 13; 113; 113) of the lamp housing using a magnetic force, thereby enabling adjustment of the beam direction (A) of the lighting unit in relation to the lamp housing.

An LED lighting assembly including a sidewall having an outer periphery with a dimension exceeding a maximum opening dimension of a standard-sized light bulb ceiling recess; at least one LED at least partially disposed within the sidewall; a plurality of heat dissipating fins between the sidewall and the LED; and a plurality of air flow channels, each having an air flow intake port defined by a lower portion of the sidewall and at least one of the heat dissipating fins; and an air flow exhaust port defined by an upper portion of the sidewall and at least one of the heat dissipating fins. Heat generated by the LED is transferred to the heat dissipating fins so as to drive a continuous flow of air into the air flow intake port and out of the corresponding air flow exhaust port of each of the air flow channels.

An egg candling device according to the present invention includes at least an egg input and alignment unit for installing trays with eggs to be tested taken out from an incubator on a transporting means. An egg candling unit determines goodness or badness of eggs to be tested in the tray transported from the egg input and alignment unit, and specifies defective eggs. A disposal unit picks up the eggs determined as defective eggs in the egg candling unit. The egg candling unit includes light sources arranged above, a lift unit for lifting up the eggs to be tested installed below the tray and causing the eggs under test to contact the light source. A determining unit determines the goodness or badness of the eggs illuminated by the light source. A notification means specifies the position of the egg determined as a defective egg by the determining unit, and notifies the position to a disposal unit. The lift unit includes an egg holding base having a smaller diameter than diameters of eggs to be tested, a moving means for moving the egg holding base up and down, a tested egg holding unit has plate-like elastic members provided around the egg holding base at specific intervals and extending at a specific length above from the egg holding base.

The present invention provides a light-emitting panel attachment structure, a light-emitting panel aligned-arrangement structure, and a light-emitting panel that enable light-emitting panels to be arranged with no gap therebetween on an installation surface such as a ceiling. An attachment side fitting part is turnably attached to a coupling part. An attachment device is changeable between a parallel orientation in which the light-emitting panel is parallel to the installation surface and an intersecting orientation in which the light-emitting panel faces a direction intersecting the installation surface, along with the turn of the attachment side fitting part. When the light-emitting panel is attached to the attachment device, the attachment device is changed to or maintained in the intersecting orientation, and either the light-emitting panel or the attachment device is moved to slide parallel to an emission surface to fit a panel side fitting part with the attachment side fitting part.

A vehicle pane with a light guide layer on the pane inner face and a lighting device which introduces light of a light source into the light guide layer by means of a light-coupling device. The light-coupling device has at least one light-coupling element that has a base surface and is optically connected to a light guide layer inner face, which faces the vehicle interior, via the base surface. The light-coupling element may have a light-coupling region which lies opposite the base surface and on which the light source has at least one LED is positioned, said light source emitting light into the light-coupling element via the light-coupling region.

A lighting arrangement comprising a lighting unit, comprising a light source arranged to emit light, and a housing comprising a reflective inner surface and an opening extending in a plane, P. The opening is oppositely arranged the reflective inner surface, wherein the lighting unit is rotatably fastened to a first rotation axis, Ai, of the housing. The first rotation axis, Ai, is arranged adjacent the opening and parallel to the plane, P, and the lighting unit is rotatable around the first rotation axis, Ai, between a first position and a second position, through the opening. In the first position, the lighting unit is at least partially enclosed by the housing, wherein the lighting unit is arranged to illuminate the reflective inner surface for an output of the light through the opening, and in the second position, the lighting unit is arranged at least partially outside the housing.
