A lamp shade or cover that can be readily switched from a translucent-opaque mode to a transparent mode if the shade or cover from a material with transparency properties that can be modulated. A layer of liquid crystals encapsulated between transparent electrodes is included in the shade. Normally, the liquid crystals are randomly oriented and diffuse light so as to create a translucent state. When a direct current voltage is applied across the transparent electrodes, the liquid crystals become oriented and essentially transparent. Application of a pulsed or alternating current voltage can be used to modulate the degree of transparency.

A low beam optical module includes a lens, a light-shielding sheet and at least one light concentrating portion. The light-shielding sheet includes a light-shielding sheet body. An upper edge of a front end of the light-shielding sheet body comprises a low beam cutoff line structure. A front end surface and the rear end surface of the light-shielding sheet body are transparent. The light concentrating portion is connected to a rear end of the light-shielding sheet. The lens is arranged in front of the light-shielding sheet, and an outer contour surface of the at least one light concentrating portion is engaged with a lower surface of the light-shielding sheet body—the light-shielding sheet body can receive emitted light of the light concentrating portion and refract the light from the front end surface to the lens. The projected light forms a low beam region III beam shape. A low beam illumination module, a vehicle lamp and a vehicle includes the low beam optical module.

A system and method are disclosed for a lamp that includes a unit having a slit. The slit receives various inserts that allow the lamp to adapt in appearance for changing the décor of a room and/or provide information to a user in proximity to the lamp.

The invention provides a lighting device (1) comprising a housing (2) including a solar-power unit and a lighting element, and a shade (3) connected to the housing (2), wherein the shade (3) is releasably connected to the housing (2) and loosely rests on an external surface of the housing (2) when connected thereto.

A lighted tile for false panel, including a frame having a bottom and sides that extend projecting from the bottom, a backlighting system having a series of lights attached to the bottom, and a stretched flexible sheet that extends between the sides facing the lights. The lights are light-emitting diodes, and the sheet is secured to the sides of the frame.

A lamp shade is provided for covering a light source. The lamp shade has a hoodlike base body which is open at least at the bottom and at least partly transparent, which is placed over the light source and covers it. The base body can have on its outer surface at least one encircling indentation, in which a decorative ring is adapted to be fitted and braced there.

A lighting system comprises at least one excitation source (5), preferably an LED, operable to generate and radiate excitation radiation of a first wavelength (λ.sub.1); a shade (4) configured to at least in part surround the at least one source (5) and remotely located thereto; and at least one phosphor (16) provided in or on at least a part of the shade (4), wherein the phosphor (16) emits radiation of a different wavelength in response to incident excitation radiation. The phosphor can be provided on a part of an outer or inner surface of the shade. Alternatively, or in addition, the phosphor is incorporated within the shade. The lighting system finds particular application as a hanging, a desk, a floor standing, a wall mountable, a spot, an outdoor or an accent lighting fixture.
