A backlight illuminator system involving a molded body produces a light illustration atmosphere by combining, with the molded body, an irradiation spectrum of indirect light composed of backlight from a rear projection plate behind a molded body, and which shows the features of the molded body with the faint backlight and defines the contour of the molded body. This backlight illumination system for a molded body includes: the molded body having a forward face, an illumination element provided toward the rear side of the molded body and which illuminates a back face of the molded body; a light transmitting through-hole that is in a rearward irradiation direction of the illuminating body; and a rear projection plate disposed away from the back face/rear side and the illuminating element and which is larger than the outer form of the molded body. The light irradiated onto the rear projection plate from the illumination element defines the contour of the molded body as a backlight reflected from the rear projection plate and the front side of the molded body due to the backlight.

An multimodal variable beam angle washlight and dynamic color flower effect luminaire is described employing multi colored LED array and a collimating partial homoginizing light guide which rotates paired with a rotating multifaceted prism which can selectively engage the light beam and be rotated while engaged. and further paired with a diffusion arm and zoom lens which converts the fixture into a variable angle wash light.

The invention relates to an illumination device comprising a plurality of light cells arranged in a row, wherein each of the light cells comprises an illumination element configured to emit light, a rectangular front lens, and a light guide configured to guide the light emitted from the illumination element to the rectangular front lens, and to an illumination device comprising a housing in which the plurality of light cells are arranged, wherein each light cell is separated from a neighboring light cell in the row by a separator which separates an edge of the front lens from one of the plurality of light cells from the edge of the front lens of the neighboring front lens by a first width, wherein the plurality of light cells comprise outer light cells in where a side surface of housing abuts one of the edges of the corresponding front lens of the outer light cell, wherein the side surface abuting one of the edges of the front lens has a thickness which is half of the first width.

A light emitting device (1) comprising at least one light source (2), and a light guide unit comprising at least a first light guide (3) and a second light guide (4) each comprising a light input end surface (6, 31, 41) arranged to, when in operation, receive light emitted from the at least one light source and a light output surface (7, 32, 42), at least a part (8) of the first light guide and the second light guide near the light output end surface being bent in a bending radius (R), at least the first light guide of the light guide unit being ring-shaped in cross section, and the first light guide and the second light guide of the light guide unit being arranged in a nested relationship.

A light pipe device may have a substantially U-shaped base with first and second leg portions. One or more light pipes may extend from one or both of the leg portions. The light pipe device may be mounted to a printed circuit board (PCB) by clipping the U-shaped based onto an edge of the PCB.

An automated luminaire includes a light engine having a multi-color LED array light source, a light guide which incompletely homogenizes such that colored light beams visibly retain separation and individual color, and a zoom lens system that projects the incompletely homogenized light beams in a spreading pattern that opens and closes as lenses are moved toward and away from the light guide.

The present disclosure provides a new string lamp, including a power line provided with string lamp bodies that are arranged in sequence. Each string lamp body includes a lamp cap part and a lamp bulb part. The power line penetrates through an inside of the lamp cap part and is electrically connected to the lamp bulb part. The inside of the lamp cap part is provided with a plurality of metal terminals. Each metal terminal has an upper end provided with a pointed penetrating part. The pointed penetrating part of each metal terminal penetrates through a plastic sheath of the power line and is electrically conductive to a line core of the power line. The lamp bulb part is divided into a plug-in type lamp bulb or a screw type lamp bulb.
