A light bulb apparatus includes a glass housing, a sleeve housing, a light source plate, a sleeve connector wrapping and an Edison cap. The glass housing defines a tubular part and a trumpet part. The sleeve housing includes a neck part and a protruding part. The neck part is enclosed by the tubular part of the glass housing. The protruding part is exposed outside tubular part. The light source plate is fixed to the sleeve housing. The sleeve connector wraps an exterior surface of the protruding part. The Edison cap is attached to the sleeve connector.

A lighting device includes a light permeable body which has an aperture through which light enters the body. A light source is moveable relative to the body to enable the lighting device to adopt selectively one of a first configuration and a second configuration. In the first configuration, the light source is positioned over the aperture so that light emitted by the light source passes through the body before illuminating the room. In the second configuration, the light source is spaced laterally from the aperture so that the room is illuminated directly by light emitted from the light source.

An electric candle device that resembles a real was candle includes an outer shell with an uneven edge around the top of the outer shell. The device includes one or more light emitting elements positioned within a cavity inside the outer shell and that emit beams at a non-zero angle with respect to a longitudinal axis of the electric lighting device to provide illumination from within the cavity in an upward direction and reaching above the top surface after passing through the opening. An optical element is positioned to receive light from the one or more light emitting elements and to direct the received light toward the top surface. The optical element has a focal point to change one or both of a size and direction of the light received prior to projecting the light in the direction of the top surface.

A monobloc optical element including a first end including a plurality of light inlets distinct from one another via which rays of light enter the optical element, the optical element including a second end via which the rays of light exit together, the second end being configured to shape a beam of light external to the optical element, the optical element being defined by an axis passing at least through the first end and through the second end, characterized in that the optical element includes at least a first contact zone dedicated to referencing it mechanically along the axis and at least a second contact zone dedicated to referencing it mechanically in a direction transverse to the axis, the second contact zone being closer to the second end than to the first end.

A lighting device according embodiments comprises: a housing including first and second back covers having arcuate inner surfaces; a recess opened to the lower portions of the first and second back covers; a transparent sheet disposed in a diagonal line configuration on the recesses of the first and second back covers; a light emitting module between the recesses of the first and second back covers; a heat dissipating body on which the light emitting module is disposed; and a first reflective sheet reflecting light onto inner surfaces of the first and second back covers, wherein the heat dissipating body includes a heat dissipation part having the first and second light emitting modules disposed thereon, and a reflective part disposed between the heat dissipating part and the bottom portion of the transparent sheet, and the first reflective sheet has multiple reflective surfaces.

First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.
