Abstract: A lighting device includes a cover, a cap, a central post having opposite ends coupled to the cover and the cap respectively, and a plurality of first and second frames. The cover and the cap both form a plurality of circumferentially distributed slots opposite to each other. The first and second frames have ends respectively fit into the slots of the cover and the cap and each frame carries at least one light-emitting diode. As such, a light-emitting diode lighting device that is hollow, light-weighted, and exhibiting excellent heat dissipation is formed.

Abstract: A safe light emitting device includes a reflective housing with an open end, a support coupled to the reflective housing, a holder, and a lamp. The holder is positioned on the support and is remote from the open end of the reflective housing. The lamp includes a bulb and a connector connecting the bulb to the holder. The bulb defines a concavity in an outer surface thereof.

Abstract: A foldable element support made from planar sheet of material that can be formed by folding into a support for positioning and securing a refractor lens to a luminaire housing. The foldable element support is a planar sheet that has a central base having a central opening, a plurality of foldable securing arms formed into the central base for attaching the support to a luminaire housing, and a plurality of peripherally-arranged support flanges for supporting and positioning the upper rim of the refractor lens in proximity to the luminaire housing. The folded support can be manipulated into the folded configuration by hand, with hand tools, or by a machine.

Abstract: A reflective lamp in which the light source is connected to the reflector through a stirrup and in which either or both the reflector and the light source can be axially adjusted but the light source lies externally of the reflector shell.

Abstract: An adaptor kit or system for use with conventional can light fixtures to adapt the can light fixture for use as a hanger assembly for ceiling fans, for example, includes a spider plate that is hung onto the can height adjustment screws and a mounting plate to which a cross-bar or other mounting hardware is attached. Adjustment screws are adjusted to control the distance between the spider plate and the mounting plate.

Abstract: A do-it-yourself lamp rod is formed by a retaining seat and an inserting rod inserting into the retaining seat. The retaining seat is locked to the inner side of a wire connecting box, and a rectangular inserted hole of the retaining seat has a positioning block therein. Thereby, an inserted hole and the positioning block can be engaged. A limiting ring is locked to the inserting portion of the retaining seat. As the limiting ring is released, then the inserting rod can be pulled out. The wire connecting box and inserting rod can be detached so as to reduce the volume for storing, transferring and packaging. Thereby, the user need only insert the inserting rod into the wire connecting box and then lock the limiting ring and thus the assembly of the present invention is completed. Therefore, the present invention can be assembled by users.

Abstract: A one-piece attachment for a general-diffuse miniature reflector has either the lamellae resting upon the rim of the reflector and engaging behind it with formations on the lamellae, or a support ring with handle like elements engaging the rim form behind, the lamellae or blades being connected by trips with the ring so that the lamellae are all integral and in one piece with one another.

Abstract: Described is an adjustable flood light fixture suitable for outdoor use which can adjustably cut-off unwanted glare through the use of a truncated cone shroud which can be rotated 360.degree..

Abstract: A mounting block of a lighting fixture includes a plurality of tilting screw holes inclinedly formed in the block for detachably mounting a plurality of supporting leg members in a bottom portion of the block, and a central hole vertically formed through the block for detachably securing a central post of a lamp socket or a shade in the central hole, whereby upon positioning of the mounting block on a lower position of a lighting fixture, the mounting block will serve as a supporting base of the lighting fixture; and upon positioning of the mounting block on a middle portion of a lighting fixture, the mounting block will serve as a lamp holder for directly securing a lamp socket and a shade on the block; and upon positioning of the mounting block on an apex of a lighting fixture, a fantastic pyramid structure of lighting fixture will be formed by suspending the shade and lamp socket on the supporting leg members protruding inclinedly downwardly from the mounting block.

Abstract: A lighting device of the free-standing type, capable of diffusing beams of light rays propagating through and emitting from the optical wave guides. A reflecting member is placed opposite the exit end of the optical wave guides to diffusingly reflect and diverge the light rays issuing from the optical wave guides thereby to light up a wide area with soft light rays.

Abstract: A collapsible lamp shade which can be assembled quickly and easily in any desired one of a variety of interchangeable external configurations comprising an interchangeable shade member formed of one of various flexible fabric materials having upper and lower continuous collar portions, upper and lower interchangeable hoop members, each including an outer circumferentially extending sidewall around which one of the shade member collar portions is located, and a substantially horizontal shelf portion which maintains the location of each collar portion. A plurality of support rods extend between the opposed hoop members to stretch the shade member, while, conversely, the stretched shade member maintains the support rods in a fixed position within the hoop members. One of various contour ring members may be located over a sidewall of and against a shelf portion of one or both hoop members to give a desired interchangeable outer configuration to the shade member and an interchangeable inner liner may be provided.
