An LED lighting device includes a transparent cover member arranged at an exterior member or an interior member and covering an LED element and a light emitting surface of the LED element mounted on a substrate, and a light transmission member receiving emission light from the light emitting surface of the LED element at a light inlet end and operating as a light transmission path. The light transmission member is integrated with the LED element mounted on the substrate together with the cover member using a transparent resin by insertion molding.

Methods and apparatus for providing circadian-friendly LED light sources are disclosed. A light source is formed to include a first LED emission (e.g., one or more LEDs emitting a first spectrum) and a second LED emission (e.g., one or more LEDs emitting a second spectrum) wherein the first and second LED emissions are combined in a first ratio and in a second ratio such that while changing from the first ratio to the second ratio the relative circadian stimulation is varied while maintaining a color rendering index above 80.

A method of fabricating a decorated molding article includes forming an all-in-one coating on a substrate and performing a curing step, thereby forming a composite layer structure with a protective effect, a color effect, and a bonding effect. The composite layer structure may form a molded film with better physical properties (e.g., higher hardness, better protection effect, and the like) after the blister molding process. Therefore, the molded film of the embodiments may be applied to a laser engraving process to form a variety of light-transmitting decorated molding articles.

A sensor system includes a first sensor, a second sensor, a cover, and a control device. The first sensor detects, with first light, a state of a first area located outside a vehicle and outputs first detecting information corresponding to the state. The second sensor detects, with second light, a state of a second area located outside the vehicle and at least partially overlapping with the first area, and outputs second detecting information corresponding to the state. The cover covers at least one of the first and second sensors while forming a part of an outer face of the vehicle and allows passage of at least one of the first and second light. The control device detects an abnormality of the cover based on an inconsistency between the first and second detecting information that are outputted for an area where the first area and the second area overlap.

A vehicle built-in electric jack system, including a plurality of electric jacks capable of lifting a vehicle. The plurality of jacks operates using a 12-volt power supply. The plurality of jacks are telescopic jacks. Each jack is made from a plurality of cylinders. The cylinders are apportioned such that each cylinder for a jack fits inside of the previous cylinder. Each of the plurality of jacks has a minimum of one light placed on the jack. The light is directed toward the wheel well of the vehicle. The jacks and lights are attached to a controller. The controller is located inside of the vehicle such that the jacks and lights can be operated while the user is inside of the vehicle cab. Further, each jack has a rocker switch located thereon that can control the jack to which it is attached.

A lamp for vehicle includes a light source unit that generates light, and an optical unit disposed in front of the light source unit. The optical unit includes an incident surface on which the light is incident from the light source unit and an emitting surface through which the light is transmitted to form a predetermined beam pattern. The incident surface of the optical unit includes a plurality of divided regions that are divided in a grid shape, and the plurality of divided regions include at least a first divided region and a second divided region having different distances from a center line that connects centers of the incident surface and the emitting surface of the optical unit. In particular, the first divided region and the second divided region are formed to have different inclination angles with respect to a vertical plane in at least one direction.

A dimming mechanism, which is used for dimming a lighting unit and includes a fixed ball head connecting piece, a first adjustable ball head connecting piece, and a second adjustable ball head connecting piece; one end of the fixed ball head connecting piece is connected to the lighting unit, and the other end is connected to a support frame or lamp body; one end of the first adjustable ball head connecting piece is connected to the lighting unit, and the other end is supported on the support frame or lamp body; and a sliding slot is provided on the lighting unit, and one end of the second adjustable ball head connecting piece (1c) is slidingly connected to the sliding slot so that the sliding slot is, by means of the back and forth motion of the second adjustable ball head connecting piece, driven to rotate, and the lighting unit is, by means of the rotation of the sliding slot, driven to rotate so as to achieve dimming in a second direction. Further disclosed are a vehicle lamp module comprising a dimming mechanism, a vehicle lamp, and a vehicle. The dimming mechanism can achieve the miniaturization of the dimensions of the vehicle lamp module in the second direction, and can improve the precision of dimming in the second direction.

A lighting device comprising at least four optical devices. Each optical device has an associated light source and comprises a first surface with a plurality of micro sized facets. Each facet has a respective orientation and said plurality of facets has an optical axis which extends parallel to the normal vector to an average orientation of all said respective orientations. The optical devices are divided over at least two sets of optical devices which are designed to mutually issue a different pattern during operation as the optical devices of different sets are arranged in a mutually alternating manner.

A dimming mechanism, comprising a fixed ball head connecting piece having one end connected to a lighting unit and another end connected to a support frame or lamp body; a first adjustable ball head connecting piece having one end connected to the lighting unit such that the lighting unit rotates to achieve dimming in a first direction; and a second adjustable ball head connecting piece having one end slidingly connected to a sliding slot provided on the lighting unit so that by means of the front and back motion of the second adjustable ball head connecting piece, the sliding slot is driven to rotate, and the lighting unit is, by means of the rotation of the sliding slot, driven to rotate so as to achieve dimming in a second direction. Further disclosed are a vehicle lamp module comprising a dimming mechanism, a vehicle lamp, and a vehicle.

A light bulb locking device (11) for mounting to a lamp reflector unit (5) having a mounting aperture for receiving a replaceable light bulb (9). The locking device (1) includes: a resilient retainer clip (13) with a clamp portion (41) for connecting to a lamp reflector unit (5), and a bracket body (15) for engaging a light bulb (9) in the lamp reflector unit (5).
