A luminous film has a plurality of light-emitting diodes, a carrier layer and a light-conducting layer having microoptical structures which make it possible to deflect multidirectionally emitted light in a common emission direction of the luminous film, in order to allow uniform illumination of the luminous film surface with a low light-emitting diode population of the luminous film.

A luminaire (10) has first light source (30) which provides light into a light mixing chamber (20) such that un-collimated light reaches the light output face (26) of the light mixing chamber (20), and a second light source (32) which provides collimated light to the light output face (26). The luminaire (10) can thus produce a diffuse flat light output and/or a directed partially collimated light output for example for task lighting.

A lighting fixture includes a housing, a first light source, a light guide plate, and a second light source. The housing has an inner cavity and a mounting hole, the mounting hole communicates the inner cavity with an external environment of the housing, the light guide plate is installed in the mounting hole. A side of the light guide plate faces the inner cavity, the other side of the light guide plate faces an outside of the housing. The second light source projects second light to the light guide plate, the second light is capable of being projected to the outside of the housing through the light guide plate. The first light source projects first light, and is configured such that the first light is projected to the outside of the housing through the light guide plate, and the housing is a non-light-transmitting housing.

A lighting device disclosed in an embodiment of the invention includes a substrate; a light source including a plurality of light emitting devices disposed on the substrate; a resin layer disposed on the substrate; and a first diffusion layer disposed on the resin layer, wherein the resin layer includes a first resin portion disposed on the light source, and a second resin portion adjacent to the first resin portion and disposed on the substrate. The upper surface of the first resin portion has an inclination and is spaced apart from the first diffusion layer, the second resin portion includes a material different from that of the first resin portion, and the second resin portion based on the upper surface of the substrate. The height of the upper surface may be greater than the lowermost height of the upper surface of the first resin portion.

A ruggedized, high efficiency, diffuse luminaire with a shaped lens diffuser that is composed of a semi-soft, flexible material that helps withstand damaging impacts and protects the internal electrical components. The lens diffuser may enclose one or more internal mirrors or employ an innovative Fresnel-like lens that projects light omni-directionally and that wraps around the inside of the lens for more efficient distribution of illumination and the elimination of up and down loss through re-projecting vertical losses onto the horizontal plane. The lens diffuser may incorporate a UV filtration compound molded directly into the materials composing the lens rather than applied or painted onto the surface or surfaces of the lens. The lens diffuser may incorporate two additional innovations that better enable the reduction of glare through varying the thickness of the lens diffuser, based on its relative proximity to the bulb(s) or lamp(s), and/or applying a patterning of reflective, semi-reflective or non-reflective material to the inside of the lens diffuser relative to the proximity to the illumination source to reflect away a portion of the light and thereby attain an even distribution of light across the surface of the lens without having to ensure that the lens surface is located equidistant or nearly equidistant from the lamp or lamps within the lens.

A mobile emergency light device includes a casing (1), a moving closure cover (2), a translucent lens (3), an electronic circuit board (5) for control, and a combined reflector (4), in which the combined reflector (4) has an inverted bell shape and is open at both ends, in which the electronic circuit board is securely connected to the combined reflector (4), and provided with a plurality of light-emitting diodes (LED), suitably angled towards the combined reflector (4), and in which the casing (1) forms inside this a cylindrical cavity (13), whose interior houses an automatic switch, driven by the base of the casing approaching a ferromagnetic material.

This disclosure discloses an illumination apparatus. The illumination apparatus comprises a cover comprising a second portion and a first portion, and a light source disposed within the cover. An average thickness of the first portion is greater than that of the second portion.

Illumination devices are described for illuminating a target area, e.g., floors of a room, using solid-state light sources. In general, an illumination device includes a first light guide extending along a first plane, the first light guide to receive light from first light emitting elements (LEEs) and guide the light in a first direction in the first plane; a second light guide extending along the first plane, the second light guide to receive light from second LEEs and guide the light in a second direction in the first plane opposite to the first direction; a first redirecting optic to receive light from the first light guide and direct the light in first and second angular ranges; and a second redirecting optic to receive light from the second light guide and direct the light in third and fourth angular ranges, where the first, second, third and fourth angular ranges are different.

A lamp control system for vehicles includes a rail provided on a roof of a vehicle and configured to extend in a longitudinal direction, a lamp module slidably connected to the rail to slide in a direction of extension of the rail, and including lamps configured to emit light to an interior of the vehicle, a sensing unit configured to detect the number of passengers riding in the vehicle, positions of the passengers, or a position of cargo loaded in the vehicle, and a controller electrically connected to the lamp module and the sensing unit and configured to control operation of the lamp module based on the number and the positions of the passengers or the position of the loaded cargo, detected by the sensing unit.

An example embodiment of a backlit lamp comprises a housing, a forward facing directional light source and a rear facing directional light source. The housing may comprise a bowl portion comprising a first joining end and a forward emitting end; and a neck portion comprising a second joining end. The bowl and neck portions are joined at the first and second joining ends. The forward facing directional light source is mounted within the housing and configured to emit light in the direction of the forward emitting end. The rear facing directional light source is mounted within the housing and configured to emit light in an opposite direction from the light emitted by the forward facing directional light source. In an example embodiment, the forward facing and rear facing directional light source comprise light emitting diodes (LEDs).
