The purpose of the present invention is to realize a lighting device of thin, low power consumption and small light distribution angle. The present invention takes the following structure to realize the above task:

A lighting device comprising:

a disc shaped light guide, having a main surface and a rear surface, including a first hole at a center,

a disc shaped reflection sheet, disposed at the rear surface side of the light guide, including a second hole at a center,

a prism sheet, disposed at the main surface side of the light guide, including a concentric first prism array,

wherein a reflection mirror is set in the first hole of the light guide at the side near to the prism sheet,

an LED is set opposing to the reflection mirror.

The present invention relates to a luminous vehicle sunroof that includes a first glazing with first and second main faces, a light-emitting element such as an OLED or QLED and a collimating optical system with one or more optical films.

The invention relates to a light fixture (100) having: an elongate light source, which is formed by multiple LEDs (60) or LED clusters arranged one behind the other in the longitudinal direction; a primary optical system (20), which is assigned to the light source and is formed by multiple pot-like reflectors (25), which are arranged one behind the other in the longitudinal direction and each widen in a divergent manner from the light source in a light emission direction of the light fixture (100); and a secondary optical system (30), which follows the primary optical system (20) in the light emission direction and is formed by a planar element consisting of a transparent material, wherein the element has light-refractive structures (35).

The invention relates to a luminaire (100), comprising lighting means (18) and a cover (20), which has at least one planar region (25) for emitting light, the planar region for emitting light (25) consisting of a transparent material and being provided, on at least one side, with a structure (26), and a plate-shaped light-influencing element (30) being arranged between the lighting means (18) and the planar region (25) for emitting light, a pattern (35) being printed on the light-influencing element.

A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

The purpose of the present invention is to realize a lighting device of small light distribution angle and less leakage light and further to realize a lighting device in which the light beam is easy to control. The following is an example of the structure to meet the above purpose. A lighting device including: a light guide; LEDs set at a side surface of the light guide; a prism sheet set on a major surface of the light guide, in which a first louver which extends in a first direction and, a second louver which extends in an orthogonal direction to the first direction are superposed on the prism sheet.

Provided is a lamp for a vehicle. The vehicle lamp comprises a light source unit for generating light, and a lens unit for forming a predetermined beam pattern by allowing the light incident through a plurality of incident lenses from the light source unit to be emitted through a plurality of emitting lenses corresponding to each of the plurality of incident lenses. The plurality of incident lenses comprises a first incident lens for allowing the light incident from the light source unit to be emitted in a first direction, and a second incident lens for allowing a first portion of the light incident from the light source unit to be emitted in the first direction, and a second portion of the light to be emitted in a second direction different from the first direction.

Implementations disclosed herein include optical sheets comprising one or more regions including one or more optical elements. Each of the one or more optical elements includes a plurality of microstructures. The one or more optical elements can be configured to tailor the radiation pattern output from a source of illumination. The one or more optical element can be further configured to impart a visual appearance to the optical sheet that is different from a standard lenticular or prismatic sheet. In various implementations, the one or more regions can be demarcated from each other or the surrounding by borders. The borders of the one or more regions can be configured to form one or more letters, one or more symbols or logos for identification and/or security purposes. Various implementations of the optical sheet can include nano-particles in addition to the optical elements to enhance the aesthetic quality of the optical film.

An anti-glare film for a light source is disclosed. The light source may be a light source with a Lambertian distribution, such as an LED light source. The anti-glare film may include a micro-frustum array to reduce the angular distribution of the light source and thus reduce glare. In some implementations, anti-glare film may further include a light shaping diffuser.
