Abstract: The high pressure discharge lamp has refractory electrodes each having a top and a winding of refractory metal wire, which has turns and is, in an area thereof remote from the top, secured to the electrode. The turns of the winding are made to have torsion. Thereby an accurately defined position with respect to the top of the electrode is obtained. The direction of the torsion is opposite to the direction of the turns, which causes neighbouring turns to press one against the other.

Abstract: In a lamp main body in a discharge lamp provided in a lighting apparatus of an edge-lighting type which is used as a back-lighting section of a liquid crystal display apparatus, refractive indexes are distributed such that a light emitted from an inner space traveling in the lamp main body can be guided to a specific direction. In other words, the lamp main body is divided into a plurality of portions and the portions are formed such that refractive indexes become gradually smaller from a light converging side towards a back surface side which is opposite to the light converging side. With this arrangement, a discharge lamp, which is capable of emitting a light from a surface of the lamp main body to a specific direction, can be obtained. Moreover, when the discharge lamp is used, efficiency of utilization of a light is improved, thereby making it possible to obtain a lighting apparatus with high surface brightness and low power consumption. As a result, a liquid crystal display apparatus with high brightness and low power consumption can be obtained.

Abstract: An electrodeless discharge lamp has a thinner wall portion located proximate a position of high applied power. Since the heat capacity of the thinner wall portion is smaller then the remainder of the bulb wall, the thinner wall portion cools faster when the lamp power is turned off, and the condensable part of the fill tends to condense at this bulb wall portion. When the power is turned on again, since the thinner wall portion is located at a position of high power application, the fill is available in such region to be evaporated, thereby resulting in more rapid starting.

Abstract translation: 无电极放电灯具有靠近高施加电力位置的较薄的壁部分。 由于较薄的壁部分的热容量小于球形壁的其余部分，所以当灯泡电源关闭时，较薄的壁部分更快地冷却，并且填充物的可冷凝部分在该灯泡壁部分倾向于冷凝。 当再次接通电源时，由于较薄的壁部分位于高功率施加的位置，所以填充物可在这样的区域中被蒸发，从而导致更快的启动。

Abstract: Fluorescent lamp energy efficiency is improved by providing geometric formations on the surface to which the phosphor coating is applied. By such geometric formations, a greater oblique surface area is available for receiving a desirably thin phosphor coating such that greater and more uniform visible light output is obtained from the device for a given energy input, i.e., greater relative to that possible with smooth surfaces receiving the phosphor coating. In the illustrated embodiment, the interior surfaces of an enclosure include V-shaped groove formations for increasing the interior surface area and establishing oblique orientation relative to approaching UV light rays. A UV light source is placed within the enclosure for excitation of a phosphor coating applied to the interior surfaces of the enclosure. The invention is particularly well adapted for use as a backlighting system in an active matrix liquid crystal display device.

Abstract: A backlight comprising a serpentine fluorescent tube nested in a uniquely shaped reflector. Much of the light emitted from the tube is directly emitted to a bounded image plane.

Abstract: An electric lamp arrangement includes a reflector (10) having first and second mirror walls (12 and 22), which in axial sections are curved according to circular arcs (13, 23), the centers of which lie in an area between lines (15, 16) enclosing angles .beta. and .gamma. with a plane P defining the largest diameter (d), and in an ellipse-shaped area Q, respectively. The reflector has a relatively small, light-emitting window (30) of at most 0.7 d, disposed opposite a lamp base (1). An electric light source (3) is disposed within the reflector (10) near plane P and an axis (11). The reflector (10) may be integral with a lamp vessel (5) to give a reflector lamp or a pressed-glass lamp. Alternatively, the light source may have an envelope and may be secured within the reflector to constitute a lamp-reflector unit. The reflector effectively shapes radiation emitted by the light source into a wide beam of high intensity. Embodiments provide an equal illumination of a large area by means of several light sources arranged beside each other. Other embodiments provide a homogeneous illumination of a relatively large area.
