摘要： A HID lamp comprises a discharge tube with two ends. A shroud surrounds the tube. Shroud clips have arcuate portions engaging the shroud periphery and transverse portions spanning the shroud diameter and grasping and positioning the tube ends. A shroud rod is attached between the clips to maintain their positioning. An offset electrical lead-in connects the first electrode terminus, and has a first section extending transversely to the first electrode, a second section extending parallel to the shroud, a third section extending toward the shroud, and a fourth section extending parallel to the shroud. An offset electrical lead-in retaining clip is affixed to the shroud and the fourth section of the offset electrical lead-in retaining clip.

摘要： The present invention aims at providing a metal halide lamp that (i) prevents a decline in the lumen maintenance and a deterioration of quality in appearance due to the coloring of a casing tube surrounding the arc tube, and at the same time (ii) achieves high luminous efficiency. A metal halide lamp (1) has a pair of electrodes (20a&b) placed in an arc tube (3) made of translucent ceramic, and a sodium halide is enclosed therein. The metal halide lamp (1) satisfies L/D 4, where L (mm) is the length of the space between the electrodes (20a&b) and D (mm) is the internal diameter of the arc tube (3). The metal halide lamp (1) has a casing tube (2) surrounding the arc tube (3), at least around a portion between the electrodes (20a&b). Here, R/r 3.0 is satisfied, where R is the internal diameter of the casing tube (2) and r is the external diameter of the arc tube (3), within a region positionally corresponding to, in a radial direction of the arc tube, the space between the electrodes (20a&b), on a cross-sectional surface where an outer circumference of the arc tube (3) comes closest to the internal circumference of the casing tube (2).

摘要： The invention relates to a fluorescent lamp (1) adapted for cold environments, which comprises an elongated main tube (11), fixing devices (12) at each end of the fluorescent lamp (1) for fixing the fluorescent lamp (1) in a light fitting (27), two electrodes (15) placed inside the main tube (11), a heat-insulating outer tube (20) that surrounds the main tube (11) and creates an airspace (22) between the main tube (11) and the outer tube (20). Each fixing device (12) comprises an end cap (41) with a radial part (41b), that delimits an outer end plane of the fluorescent lamp (1), and with an axial peripheral part (41a), that is connected to an end of the outer tube (20). An axial spacer (29, 31) with low heat conductivity has a first end part (33) that is connected to an end (34) of the main tube (11) and a second end part (38) that adjoins the outer end plane and keeps the main tube (11) separate from the end cap (41) in order to reduce the transmission of heat from the main tube (11) to the end cap (41) and the outer tube (20).

摘要： A spring clip (10) has a base (12) in a first plane and has an aperture (14) centrally located therein. U-shaped projections (16) and (18) are provided on the base (12) and are formed from first and second upstanding walls (20) and (22) and third and fourth walls (24) and (26), at each end of the base (12). A first lip (28) extends orthogonally between the first wall and second wall in a second plane and a second lip (29) extends orthogonally between the third wall and fourth wall, also in the second plane. The second plane is substantially parallel to the first plane but spaced therefrom. Extensions (30) and (32) are formed with the first wall and the third wall and project away from them. The extension are in substantially the same plane as base (12) and at least one flag (34) can be formed with at least one of the extensions. The flags (34) project away from the extensions (32) in a plane transverse to the first and second planes and allow the clips to be attached to a frame
