A high-efficiency linear light source focused strip lamp has a strip lamp frame, a strip lamp plate provided on the strip lamp frame, a condensing lens arranged above the light emitting direction of the light-emitting chip, and a strip lamp cover connected to the strip lamp frame and located above the condensing lens; the strip lamp cover is provided with a convex lens array that visually stretches the light-emitting chip along a length direction. The high-efficiency linear light source focused strip lamp performs light distribution through the concentrating lens in the vertical length direction, and achieves high-efficiency sweeping function, and in the longitudinal direction, the light-emitting chip is performed visually stretching by the convex lens arrays on the strip lamp cover, thus achieving the effect of the line light source, solves the original glare problem without affecting the efficiency.

A lamp projecting a starry sky is provided. The lamp projecting the starry sky includes at least one beam generator, a reflecting member with uneven and irregular reflecting surface, a first motor, and at least one first lens. The first motor is connected to the reflecting member through a connecting shaft, the reflecting member is driven to rotate when the first motor rotates, a light beam generated by the beam generator irradiates onto a first side of the reflecting member along an incident light path, and a light beam emitted from the reflecting member forms a moving and layering nebula projection after passing through the at least one first lens. In the lamp, after passing from the reflecting member, the light beam is magnified by the lens, so that the generated starry sky will not be too bright and dazzling, which effectively enhances the layering sense of the starry sky.

Disclosed are methods for forming a double-sided optical sheet, and a vehicle lamp assembly having the double-sided optical sheet integrated therein. A first optical pattern is imprinted on a first side of a material, and a second optical pattern is imprinted on a second side of the material, opposite the first side. The first and second optical patterns are thereby formed on opposing sides of the same sheet. When oriented adjacent a light source, the double-sided optical sheet homogenizes light emitted from the light source. For a light source having a plurality of lighting elements, the double-sided optical sheet is configured to blend light emitted from the plurality of lighting elements to form one homogenous beam of light output resulting from a single light-modifying member.

An optical projection device for projecting a linear image is disclosed. Light emitted by an array of light emitting diodes arranged along an array axis is focused in at least a direction perpendicular to the array axis and diffused in a direction parallel to the array axis, thereby generating a linear image in which light from adjacent light emitting diodes is spatially overlapped. In some embodiments, the focusing and diffusion of the light is performed by a Fresnel lens and a lenticular lens, respectively. The optical projection device may be employed to virtually mark a surface, such as a floor in an industrial setting. High power light emitting diodes may be employed to generate a linear image having an illuminance of at least 4000 lux that is focused to a distance between 7.5 and 20 feet.

A light source unit includes: a first light emission point from which a first beam is emitted; a second light emission point from which a second beam is emitted and which is disposed apart from the first light emission point in a second direction perpendicular to a first direction; a deflection element that deflects the first and/or second beam; and a first condensing optical element that focuses, on a light collection surface, the first and second beams. The first beam at the first light emission point overlaps the second beam at the second light emission point in a third direction, and on the light collection surface, the first and second beams overlap each other in the second direction and are separate from each other in the third direction.

A lighting device includes a light source configured to emit a light beam through an afocal projection optics along a propagation path of the light beam from a negative lens to a positive lens. The lighting device includes a further negative lens interposed and mobile along the propagation path of the light beam from the negative lens to the positive lens.

The optical lens has a first surface including incident regions and a second surface including emission regions. A minimum distance between the first surface of the optical lens and the first lens is 0.1 mm or more and 1.0 mm or less. A light emitted from each of the light emitting parts enters the optical lens through the first lens, the light being emitted from the first lens at a second full-width half-maximum smaller than the first full-width half-maximum, such that lights emitted from two or more of the light emitting parts are irradiated to two or more corresponding irradiation regions.

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.
