摘要:
The present invention relates to a lighting device (1) that comprises a first light source (2) comprising one or more LED devices (21). At least a deformable reflective element (3) is optically coupled to said first light source, so as to receive light from said first light source, said reflective structure comprising at least a first portion (31) having a reflective surface (310) that reflects at least partially the light (L1) received from said first light source, and a second portion (32) that is solidly coupled to said first portion. Driving means (4) are operatively coupled to said second portion (32), which induce a deformation of said second portion that in turn causes a deformation of the reflective surface (310) of said first portion. The position of the focus point (F) of the light (L2) reflected by said reflective surface can thus be varied in a controlled manner.
摘要:
An optical group with an adjustable light beam, comprising at least one lamp-holder device, at least two linear fluorescent lamps (10, 11) and a specular reflector (12); in the centre of the body (5) of the reflector (12) there are at least two curvilinear surfaces (6, 16-19), which, by varying their angular position, allow a variation in the form of the light emission of a lighting appliance, in relation to the various application requirements. Solutions such as those projected allow high efficiency levels of the lighting appliance to be maintained and obtained in particularly restricted volumes.
摘要:
An inflatable, multifunction, multipurpose, parabolic reflector apparatus 10 having a plurality of manufactured parabolic mirrors 14, 16 made from a pressure-deformable reflective covering of an inflatable ring 12 for focusing electromagnetic energy from radio frequency radiation (RF) through the ultraviolet radiation (UV) and solar energy for (1) heating and cooking, for (2) electrical power generation, for (3) enhancing the transmission and reception of radio signals, for (4) enhancing vision in low-light environments, and for (5) projection of optical signals or images. The device also has non-electromagnetic uses, such as the collection of water. A first main embodiment utilizes two reflective membranes. A second main embodiment utilizes a reflective membrane and a transparent membrane. Portability is enhanced by complete collapsing of the inflatable device.
摘要:
An adjustable reflector device is disclosed. The device consists of an adjustable double parabolic reflective skin (1, 2) with an adjustable lamp mount (12), incorporating a V-shaped perforated heat shield (17), attached. The two part reflective skin (1, 2) forms a double parabolic shape when flexed back against a reinforced spine (3). This flexible shape is secured by lenghtwise adjustable chain retainers (4) attached at both ends of the skin (1, 2). The lamp mount (12) slides onto a pair of threaded bolts (6, 7) secured to the skin and adjustment is achieved by tightening or loosening the appropriate nuts (15, 16). The heat shield (17) slides onto the lamp fitting (18) and is positioned appropriately to deflect incident heat and light. This device can be used to provide variable conditions of artificial illumination.
摘要:
A mechanism for deflecting a headlamp optical axis comprises a connecting lever (50), a bracket (40), a stepping motor (20), a front end plate (24), and a traveling block (30). The bracket (40) is attached to an outside frame (60) constituting an automotive vehicle body, and the stepping motor (20) is attached to the bracket (40) in a horizontally movable manner. The stepping motor (20) has a rotary shaft (22) which has a screw (23) formed thereon and engaging threadedly with the traveling block (30). The connecting lever (50) is attached to the outside frame (60) in a horizontally movable manner. In the mechanism structured above, when the rotary shaft (22) rotates, the traveling block (30) is caused to travel along the rotary shaft (22) thereby causing the both ends (50a, 50b) of the connecting lever (50) to move in respective arc paths, whereby an optical axis of a headlamp (10) attached to one of the both ends (50a, 50b) of the connecting lever (50) is deflected.

The invention relates to a box-type reflector (1) intended for external lamps (37), in which is a tubular lamp with its socket (36), especially a high pressure discharge lamp such as a high pressure sodium vapour lamp, burns in a horizontal position, the reflector unit (1) being delimited lengthwise (30), in reference to the longitudinal axis of the lamp, by front walls (21, 21', 22, 22'), and crosswise (11) by the sidewalls (4, 4', 5, 5', 6, 6'), the transversal axis (11) defining the inside width of the sidewalls. Inside the external lamp, the reflector unit (1) is mounted longitudinally (30) moveable relative to the socket (36), and/or at least part of each reflecting sidewall (4, 4', 5, 5', 6, 6') is formed by part of the reflector or by concave metal-coated side strips which are secured tilting in an adjustable manner on the upper and/or lower longitudinal edge, so that the inclination of the side strips (14, 15) can be adjusted relative to the transversal axis (11).
