Abstract: A vacuum processing apparatus performs processing such-as a pattern depiction with a charged beam within a process chamber evacuated to a high vacuum by an ion pump. The vacuum processing apparatus, which makes it possible to prevent the accuracy of the charged beam pattern depiction from being deteriorated by ions and electrons leaking from the ion pump, has a conductor and a voltage applying unit. The conductor is arranged in the vicinity of the suction port of the process chamber communicating with the ion pump such that the conductor is electrically insulated from the process chamber. The voltage applying unit imparts a potential differing from that of the process chamber to the conductor. Because of the potential difference between the conductor and the process chamber, the ions and electrons leaking from the ion pump are reflected or adsorbed by the conductor so as to suppress leakage of the ions and electrons into the process chamber.
Abstract: A headlamp (2; 3) of a vehicle (1) has a light source (4; 5) comprising a plurality of opto-electronic elements (11; 12; 13; 14), preferably light-emitting diodes (LEDs). At least one of these opto-electronic elements (11; 12; 13; 14) has, in operation, a luminous flux of 5 lm or higher. According to the invention, the spatial distribution of the light beam (6, 6′, . . . ; 7, 7′, . . . ) generated by the light source (4; 5) is continuously adjustable. Preferably, the light source (4; 5) comprises opto-electronic elements (11; 12; 13; 14) only. Preferably, the spatial distribution is influenced by the speed of the vehicle (1), the rotational position of the steering wheel of the vehicle (1), the weather conditions, and it can also be influenced by the driver of the vehicle (1). Preferably, the spectral characteristics of the light beam (6, 6′, . . . ; 7, 7′, . . . ) generated by the light source (4; 5) depend on the position in the light beam (6, 6′, . . . ; 7, 7′, . . . ).
Abstract: A vehicle lamp having a body, a lens, a first light source, a reflector, and a second light source. The body has a front face, a side, and an opening face, wherein the opening face is curved from the front face to the side. The lens covers the opening face of the body. A lighting chamber is defined by the body and the lens. The first light source and the reflector are arranged in the lighting chamber. The reflector includes a front side for reflecting the rays of the first light source substantially in the front direction, and also includes a reverse side. The second light source is arranged adjacent the reverse side of the reflector so that rays of the second light source are reflected by the reverse side of the reflector and are irradiated substantially to the side of the body.
Abstract: A direct lighting unit fits in opposition to an opening of a roof of a vehicle's cabin so as to illuminate a light directly the cabin. An indirect lighting unit is disposed around the outer circumference of the direct lighting unit. The indirect lighting unit contains a plurality of LEDs disposed at fixed intervals so as to emit light outward. The LEDs are controlled to indirectly illuminate the roof. When the direct lighting unit is mounted to the roof, a fixing piece supports a grooved edge portion of the indirect lighting unit so that the indirect lighting unit is immovably held between the fixing piece and the roof. Thus, the direct and indirect lighting units are simultaneously secured to the roof.
Abstract: A pool lighting apparatus including a sealed lens assembly attached to a light emitting end of a fiber optic cable. The sealed lens assembly is installed into a standard pool wall fixture and is provided with redundant seals for preventing the passage of water there between. A glass lens is provided to be either flat or convex to provide the desired field of lighting. One or more removable protective covers may be applied to the lens to provide a desired color effect within the pool.

Abstract: A decorative structure including a crab-eye style lamp without a lamp holder, has a lamp bulb on a bottom surface connected with a pair of conductors separated and positioned by means of an insulation block. A thin sleeve is combined by heat shrinking with a connecting area between the exposed conductor sections of the lamp bulb and the conductors sections. A light penetrable decoration member of any of various configurations has a positioning hole in communication with the outside and extending into the decoration member for a predetermined depth. The crab-eye style lamp completely enters the positioning hole of the decoration member to provide a safer structure and a more attractive decorative effect when the lamp bulb is illuminated and shining.
Abstract: The apparatus disclosed and claimed herein comprises an outdoor lighting fixture having a post extending down into the ground, with a short length of the post extending up above the ground. A lighting fixture, which receives a lamp, is disposed on the upper rim of the ground post. An upper post or lens diffuser is in turn disposed on the fixture, and an outer post housing is disposed over or about the ground post, the fixture, and the upper post or lens diffuser. A lens is appropriately secured to the upper post and lens diffuser and to the outer post housing. If desired, the ground post may be disposed on the surface of the ground or on a hard surface, such as a deck, or the like. Moreover, a weed guard and stabilizer cylindrical element may be disposed about the housing and on the ground to help prevent inadvertent damage from lawn care equipment, inadvertent bumping, and the like. The fixture, of course, may use a compact fluorescent lamp, an incandescent lamp, or any other desired light emitting element.
Abstract: A flexible and ornamental vehicle light cover comprises a flexible piece of sheet material with a pressure sensitive adhesive layer applied to a back surface for bonding the sheet to a vehicle lens that surrounds one of the lamps e.g., an electric tail lamp of the vehicle. The sheet material has an outline depicting a design or symbol that can be seen by an observer whether the light is on or off. The sheet has the multiplicity of punched openings in it to enable light from the vehicle lamp to pass through the sheet for preventing an unacceptable reduction in the luminous flux provided by the vehicle lamp. The sheet is thus able to be applied to the vehicle lens over the lamp by pressing the sheet onto the lens so as to intercept and block no more than the predetermined fraction of the luminous flux impinging thereon while serving to decorate the vehicle.
Abstract: A cold cathode tube having a fluorescent material coated along the inner wall thereof and the tube being filled with a small amount of gas, characterized in that the inner wall of the tube is coated with a ultra-violet ray reflective film capable of reflecting ultra-violet light, and the light emission surface at the inner side of the ultra-violet light reflective film does not coat with a fluorescent material, and the remaining region of the light emission surface at the outer wall is coated with a visible light-reflective layer. In addition, the length of the parallel section of the tube can be extended to increase lighting area, and thus the efficiency of light energy output is increased.
Abstract: An accessory lighting assembly for selectively illuminating user selected areas such as, for example, compact computer devices, books and other desired areas. The light source is directed away from user selected area for illumination and a reflective surface is selectively positionable to intercept the light emanating from the light source and re-direct it toward the user selected area. The directing of the light away from the user selected area for illumination and subsequent reflecting back toward the user selected area results in an evenly diffused light being applied to the user selected area, while completely eliminating the otherwise experienced hot spots or dark spots common in prior art accessory light assemblies.
Abstract: A reflective surface 10a of a reflector 1 in a vehicle lamp is formed in such a way that a free-formed surface 20 is created as a basic shape so as to satisfy light uniformity out of functional conditions and thin shape as a shape condition and that a reflective surface element 14 created so as to satisfy light diffusibility out of the functional conditions and transparency as an appearance condition is assigned to each of segments obtained by dividing the free-formed surface 20 into an array pattern. Particularly, the free-formed surface 20 or the reflective surface 10a is created so that luminous exitances M specified in a direction along the optical axis satisfy the condition of Mmax/Mmin≦6, whereby the above conditions can be suitably substantiated.
