Abstract: A multi view display comprising a light emitting element having an optical cavity formed by a first and a second reflecting layer, at least said second reflecting layer being semi-transparent, and a light emitting layer arranged between said reflecting layers, wherein said optical cavity is designed so that light emitted in at least two preferred viewing directions has a higher intensity than light emitted in other directions. The invention is based on interference phenomena in the optical cavity, making it possible to realize a light emitting element that intrinsically emits more light in the preferential viewing directions than in other directions. This emission profile makes the light emitting element very useful in a multi view display, reducing the problems of cross talk.

Abstract: A vehicle lamp including a projector headlight using an LED light source for a low beam can include a shade, an LED light source, an ellipsoidal reflector and a projector lens. Both a focus of the projector lens and a top edge of the shade can be located near a second focus of the reflector. The LED light source can be located near a first focus located below the second focus of the reflector. Therefore, light emitted from the LED light source can be effectively gathered near the focus of the projector lens via the reflector and can be projected via the projector lens with high light use-efficiency. The projector lens can include light dispersing portions or structures on an upside and downside thereof for reducing chromatic aberration. Thus, the lamp can project a favorable light distribution that can conform to light distribution standards for vehicle headlights and the like.

Abstract: A vehicle lamp can include a light source unit including a light guide plate with a light emission surface, and a point or line light source opposed to one end face of the light guide plate. The light guide plate can be made of a transparent plate-like material. A convex projection lens can be configured to focus light emitted from the light source unit and project the light forward in a direction of light illumination. The light guide plate can have a prism array on a rear surface thereof extending with a serrated cross section from the one end face to the opposite end face of the light guide plate, and in a direction parallel with the end face. The prism array can include a plurality of prism surfaces, with each prism surface being obliquely formed so that when light enters the light guide plate from the light source side and impinges thereon, a substantial amount of the light can be totally reflected into small angles of incidence to the emission surface.

Abstract: A luminaire system provides for mounting and accessing a light fixture housing without tools. A universal bracket is coupled to the junction box along the ceiling and engages with a top mounting plate affixed to the housing. One or more slide hooks appended to the universal bracket allows the top mounting plate to mount to the universal bracket, and a reinforced spring and locking spring keeps the light fixture housing in place, while preventing rattling between the universal bracket and the top-mounting plate. The housing can be removed from the electrical junction box through the use of a release button affixed to the housing. The button disengages the locking spring from the top mounting plate, thereby allowing the housing to swivel away from the universal bracket and junction box by way of a hanging hook. The hanging hook supports the housing when released from the universal bracket.

Abstract: A movable multi-directional light stand is revealed. The movable multi-directional light stand includes a retractable top support rod that can be received into and connected with a hollow middle support rod. The top support rod is disposed with a mounting slot on a wall, along an axial direction thereof. A sleeve with external threads is disposed around the top of the top support rod and is arranged with a guiding slot corresponding to the mounting slot of the top support rod. A retractable light rod is pivoted to the wall of the top support rod that is disposed with the mounting slot. The retractable light rod is formed by a hollow outer tube and an inner tube that slides in the outer tube and having a hook. The light stand further includes an adjustment nut with threads engaging corresponding external threads of the sleeve so that the adjustment nut can support the outer tube, locate the retractable light rod in the mounting slot and adjust the height of the light.

Abstract: In a vehicle lamp unit that is configured to be mounted on a vehicle, a semiconductor light source can be substantially covered with a first reflector and, therefore, the semiconductor light source is not visually observable (or, is difficult to see) from outside the lamp unit even when a projection lens is disposed in front of the opening of the first reflector and spaced from the first reflector so as not to contact the first reflector. Thus, a vehicle lamp unit having a novel design can be provided in which the projection lens appears as if it is floating in air and in which the semiconductor light source is not visually seen or is difficult to be seen from the outside.

The two discs are engaged with the first gear and the permanent magnet. Thereby, the permanent magnet can be rotated rapidly by means of the differential ratio of the first and the second gears to produce enough electric power.
