摘要:
The present invention relates to a parabolic reflector (1) which is placed inside fluorescent luminaires, behind each fluorescent lamp (3), and rotates at various positions around the imaginary axis of the fluorescent lamp (3), in fixed steps of 1°, 2° degrees or more, while being securely held in all rotating positions. The parabolic reflector (1) of this invention is secured in its place and rotated in the side walls (5) of the luminaire housing (2) without having to be supported on the fluorescent lamps (3). More specifically, the reflector (1) rotates in steps of 1° or 2° degrees or more and locks into each rotating position to avoid any movement in case it is accidentally pushed.

Die Erfindung betrifft eine Leuchte mit einem Gehäuse, wenigstens einem in dem Gehäuse angeordneten LED-Leuchtmittel und mit einer optischen Einrichtung, die in einem Abstand zum LED-Leuchtmittel in einem Strahlengang wenigstens eines Lichtstrahls angeordnet ist. Hierbei wird das LED-Leuchtmittel in einem stromaufwärts der optischen Einrichtung vorhandenen Brennpunkt angeordnet.
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.

La présente invention se rapporte à un dispositif projecteur antibrouillard dans lequel on fait intervenir une lentille de projection (101), tout en assurant un réglage entre la position de ladite lentille et la source lumineuse (200) du dispositif considéré particulièrement précis, et un maintien optimal de ladite lentille. D'autres avantages, tels qu'une grande compacité, une grande facilité de montage et un coût réduit de fabrication sont également obtenus grâce à l'invention. A cet effet, dans l'invention, on propose un dispositif antibrouillard présentant un support de lentille (100 ;600) dont les fonctions sont multiples : il assure le maintien de la lentille, il coopère avec un élément de réglage (201) pour amener la lentille dans une position telle que les réglementations relatives à l'orientation de la ligne de coupure sont respectées, et il assure un positionnement précis de la lentille par rapport à la source lumineuse.

An adjustable desk lamp (1) preferably includes a base (10), light ballast (12), adjustable height support (14,48), at least one support tube (16), and at least one support band (18). The adjustable height support (14,48) extends from the top of the base (10). One end of the at least one support tube (16) is attached to the base (10) and the other end is attached to the light ballast (12). One end of the at least one support band (18) is attached to the base (10) and the other end is also attached to the light ballast (12). The at least one support band (18) is supported by an end of the adjustable height support (14,48). The light ballast (12) preferably includes a base ring (82), rotary guide (84), rotary light support (86), and ballast assembly (88). The rotary light support (86) is attached to the rotary guide (84) and rotably constrained by the base ring (82). The ballast assembly (88) is pivotally retained by the rotary guide (84) and the rotary light support (86). A light bulb (116) is retained in the ballast assembly (88). The height of the light ballast (12) relative to a desk surface may be adjusted by raising or lowering the adjustable height support (14,48). The projection angle of the light bulb (116) may be adjusted by sliding the ballast assembly (88) relative to the rotary guide (84).
摘要:
A vehicle light (1) having a multi-reflex optical system comprising a light source (2), a first reflecting surface system (3) and a second reflecting surface system (5). The first reflecting surface system (3) comprises a parabolic group reflecting surface (31,33), an ellipse group reflecting surface (32) or combination thereof. The second reflecting surface system (5) comprises an ellipse group reflecting surface (51) having a first focus (f1) at the light source and a second focus (f2), and located to cover the front of the light source and to collect light rays emitted from the light source to its second focus (f2), a parabolic group reflecting surface (52) having a focus (f3) in the vicinity of the second focus of the ellipse group reflecting surface (51), and an adjusting reflecting plate (6) located in the vicinity of the second focus (f2) of the ellipse group reflecting surface (51). The second focus (f2) of the ellipse group reflecting surface (51) of the second reflecting surface system (5) is located away from, not within the optical path of, and either above or below the first reflecting surface system (3). The overall shape of the vehicle light (1) is substantially T-shaped or L-shaped.
摘要:
The invention relates to lighting apparatus. The lighting apparatus according to the invention comprises directable optical conductor (10) and a filament or halogen bulb (3) or other light source (3, 4) installed as stationary. The optical conductor (10) is articulated to the lighting apparatus preferably by means of a sleeve bearing (11, 2'), for instance, or by other means so that the position of the optical conductor in relation to the lighting apparatus and the fastening surface (2) of the lighting apparatus can be changed freely. In addition to this, the optical conductor can preferably also be attached in a manner which allows turning it around its central axis. The light beam formed by the lighting apparatus is directed by means of the optical conductor, whereby the mechanical stress caused by directing the beam does not affect the light source. Because the optical conductor and the light source are separate, and the light source (3, 4) is not within the optical conductor, the optical conductor does not warm up considerably, whereby handling it is comfortable for the user.
