A planar lighting device according to an embodiment includes a light guide plate and a reflecting member. The light guide plate has an incident surface that receives light output from a light source and an output surface that outputs the light received by the incident surface. The reflecting member faces an end surface opposite to the incident surface of the light guide plate and reflects light leaking from the end surface. A plurality of first prisms are formed on an opposite surface opposite to the output surface-of the light guide plate to be away from the output surface stepwise from the incident surface to the end surface. The first prisms cause the light reflected by the reflecting member and traveling from the end surface toward the incident surface to be output from the output surface in a first direction as first light and cause the light entering into the incident surface and traveling from the incident surface toward the end surface to be output from the output surface in a second direction different from the first direction as second light.

A configurable vehicle lighting module system includes a shared lens configured to provide a first light pattern for a first vehicle lighting function and a second light pattern for a second vehicle lighting function. The shared lens includes a mounting axis which provides a reference for mounting the shared lens on a vehicle. First internal optics are configured to direct light toward the shared lens to provide the first light pattern, and second internal optics are configured to direct light toward the shared lens to provide the second light pattern. A coupling system is configured to join the shared lens with either the first internal optics to form a first module configuration for providing the first vehicle lighting function, or with the second internal optics to form a second module configuration for providing the second vehicle lighting function. The shared lens conceals physical differences between the first and second internal optics such that the first and second light module configurations have the same appearance when viewed along the mounting axis of the shared lens.

Examples described herein relate to a molded article provided with a resin part formed with a polyolefin resin composite material, the polyolefin resin composite material containing a polyolefin resin and 10 to 150 parts by mass of cellulose based on 100 parts by mass of the polyolefin resin, wherein an area of an aggregate of the cellulose is less than 20,000 m.sup.2.

A predetermined lighting pattern is projected on a surface to be illuminated and the lighting pattern is displaced on the surface to be illuminated. A laser beam generated by a laser light source is broadened by a magnifying lens so as to generate a divergent light. The divergent light is shaped by the collimation lens into a parallel illumination light, and the parallel illumination light is caused to be incident on an incident plane of a diffraction optical element which records a hologram image. A diffracted light from the diffraction optical element forms the lighting pattern as a hologram reconstructed image on the surface to be illuminated. By translating the collimation lens by a collimation-lens drive unit along a movement plane that is orthogonal to an optical axis of the laser beam, the lighting pattern can be displaced on the surface to be illuminated.

An illumination device (10) includes: laser light sources (20) having different radiant fluxes; and diffractive optical elements (40) provided correspondingly to the respective laser light sources. A planar dimension of the diffractive optical element, which corresponds to the laser light source that emits a laser light having a minimum radiant flux, is smaller than a planar dimension of the diffractive optical element, which corresponds to the laser light source that emits a laser light having a maximum radiant flux.

The present technology provides a hot melt composition containing: styrene-based thermoplastic elastomer having a weight average molecular weight of 300000 or more; tackifier; a first paraffin oil having a weight average molecular weight of 1000 or more; and a second paraffin oil having a weight average molecular weight of less than 1000.

A vehicle lamp includes a light emitting diode (LED) drive module (LDM) including a printed circuit board (PCB) on which an electronic element for driving a light source is mounted, and an electromagnetic interference (EMI) cover coupled to the PCB to surround the electronic element, and a lamp housing including a guide portion formed in a first direction such that the LDM is coupled thereto in a sliding manner and a seating portion in surface contact with a tip portion of the LDM in a coupled state, wherein a cover pressing portion that protrudes in a coupling direction of the LDM and presses the EMI cover in a second direction may be formed in the seating portion.

An LED strip connector system for providing secure electrical and mechanical connection between LED strips comprising a male socket end, a female socket end, a locking mechanism, a gasket, a wired housing, and an end cap. The locking mechanism consists of a clip and clip catch and provides a detachable, secure, vibration-resistant mechanical connection between strips. The gasket is made of an elastic, impermeable material and is configured and positioned to establish a moisture-resistant seal between connectors, protecting the electrical connection from environmental moisture. The wired housing connects a female socket end to a power cord. The end cap protects the exposed contacts of an open socket.

A vehicular display device includes: a reflective display configured to provide display toward an outside of a vehicle; and a light emission member arranged to face a display part of the reflective display. The light emission member is configured to allow light to be incident from a display part side and light to be incident from an opposite side to the display part side to pass through the light emission member, and is configured to emit light toward the display part, which is different from the light to be incident from the display part side and the light to be incident from the opposite side to the display part side.
