The vehicle lamp according to the present invention includes: a light source; a movable shade rotating in a front-back direction and switchable to a second position where some of light from the light source is blocked; a power section having a moving shaft moving in a horizontal direction; and a power-transmitting section transmitting a moving force of the moving shaft, as a rotary force of the movable shade. The moving shaft has an engagement groove with which the power-transmitting section is engaged. The power-transmitting section includes a second arm having an engagement section slidably engaged with the engagement groove. The engagement section includes a first engagement section engaged with the engagement groove and extending in the front-back direction, and a second engagement section that has a substantially linear shape, is engaged with the engagement groove and is connected to and bent with respect to the first engagement section.

Lighting applications which are particularly difficult to light because of non-standard target area characteristics or the like would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has reached a point of diminishing returns in terms of beam control. Envisioned is an LED lighting system designed for precision lighting insomuch thatas compared to state-of-the-art LED lighting fixturessharpness of cutoff is improved while in at least some cases simultaneously allowing a steeper cutoff without undesirable beam shift. Furthermore, overall beam dimensions can be tailored fixture-to-fixture for an application without replacing an entire optic system or designing an entirely new fixture, and control of intensity distribution is improved (e.g., by avoiding striations at the edge of beam patterns). Said envisioned LED lighting system employs a number of materials not used in conventional LED lighting systems in novel ways to achieve the aforementioned.

The present invention provides a sculpture bound within the volume of a polyhedron that when, rotated about an axis of rotation and positioned in the path of a directed light source, cast shadows of a predetermined and desired form onto a surface.

Precision lighting design is a subcategory of lighting design which benefits from a concerted, synergistic effort to improve beam control; sports lighting is one such example. Beam control is improved when all light directing and redirecting devices are considered together, and insomuch that adverse lighting effects are best avoided when considering how all the lighting fixtures in an array interact with one another. To that end, envisioned is a multi-part visoring (i.e., light redirecting) and optic (i.e., light directing) system designed with consideration towards how a fixture lives in a mounted spacehow its photometric and physical presence affects other fixtures in or proximate said spacewhile demonstrating improved beam control over that which is available to general purpose (e.g., indoor residential) lighting.

Disclosed and described herein is a sharp cutoff LED lighting luminaire and methods of use thereof. Further disclosed is a modification thereof which allows baseballs or detritus trapped by the luminaire to fall to the ground. In the state of the art often designers will use the same type of LED lighting fixtures at the top of the pole as for low-mounted uplighting; specifically, taking an additional fixture similarly configured, inverting the orientation (i.e., so to project upward instead of downward), and mounting it relatively low on the pole. The envisioned sharp cutoff LED lighting fixture is better suited for low-mounted uplighting insomuch that it reduces back light, haze, internal glow, and perceived glare as compared to current LED lighting fixtures typically used for the same purpose.

A Shabbat bulb and a related method allows control of illumination without electrical intervention by a person observing strictures of Shabbat orthodox Jewish law. The bulb includes a blackout mechanism with shutter disc having at least one disc aperture for transmission of light and gear teeth; and an arm projecting radially outward from the shutter disc fitted with drive gear teeth. Manual rotation of the arm engages drive gear teeth with shutter disc gear teeth moving the disc apertures from an open to a closed position respectively allowing full or totally no illumination to exit the bulb.

A dimming device comprises a light source, a support having a light path corresponding to the light source, a light diffuser, and light shielding blades having notches. The blades and the diffuser are movably disposed on the support. The blades and the diffuser are actuated by independent actuators. The notches move into and out of the light path with the movements of the blades, and the diffuser covers a portion of notches that is within the light path when moving into and out of the light path. The diffuser's movement relative to the light path is not limited to that of the blades, so the diffuser can be precisely controlled to move into a specific position within the light path with an optimal trajectory and at an optimal time point. The diffuser is integrally formed without slots, ensuring diffusion of all light passing through the covered portion of the notches.

Described are an improved automated luminaire 12 and luminaire systems 10 employing an improved output Fresnel lens 46 with an optically planar surface 34 combined with an articulable stippling plate 47. The stippling plate 47 may be inserted and removed immediately behind and adjacent to the planar rear surface of the lens 46 in order to transform the optical system from beam optics to wash optics or immediately adjacent to another articulable lens system 29 directly the light beam toward the previously described Fresnel lens. Further embodiment may include an articulable beam spreader.

A luminaire includes an elongated housing having a long axis, a plurality of light emitters extending in a direction of the long axis, a first light shield rotatably coupled to a base of the luminaire and configured to rotate about a first axis parallel to the long axis, and a second light shield rotatably coupled to the base of the luminaire and configured to rotate about a second axis parallel to the long axis. The first light shield and the second light shield are configured to physically couple to form a combined light shield that is configured to block light emitted by the plurality of light emitters.
