Embodiment Construction
[0019] During the use of the lamp, when the lateral edge of the reflective layer is located closer to the neck from the connection area of the bulb neck to the ellipsoidal part, the temperature of the base increases, negatively affecting the putty and solder, which is Because after the light is reflected from the reflective layer at the neck, part of the light is emitted to the base.
[0020] When the lateral edge of the reflector is located closer to the burner from the bulb neck and junction area of the bulb dome to the ellipsoidal part, the luminous flux is reduced because part of the net emission reaches the upper hemisphere, reducing the luminous flux.
[0021] When the lateral edge of the reflective layer is located closer to the dome from the connection area of the bulb dome to the ellipsoidal part, the wires 11 are forced into contact with the reflective layer, generating an electric field around the working burner, which negatively affects the life of the lamp. ...

The invention related to the electrotechnical industry. Said invention makes it possible to reduce the production cost and to improve the quality.The inventive gas-discharge reflector lamp comprises a light bulb and a burner arranged on the input leads thereof. At least one half of the bulb internal surface is coated with a reflecting layer in such away that a plane crossing the parallel edges thereof is parallel to the longitudinal axis of the burner. The bulb is embodied in the form of an ellipsoid. In the area delimited by the bulb neck and dome, the transversal edges of the reflecting layer are located on the cross-sections where the bulb neck and dome gradually transform into the ellipsoidal section, The plane passing through the longitudinal edges of the reflecting layer are located from the bulb axis at a distance H and falls in the range of 0.04-0.11 of the bulb maximum diameter D. The burner is positioned in such a way that, on the cross-section passing through the center of the bulb ellipsoid, the ratio between a distance I from the burner axis to the closest surface of the reflecting layer and a distance L from the burner axis to the edge of the reflecting layer located on the longitudinal section ranges from 0.56 to 0.68. A least one input lead is arranged between the burner and the reflecting layer on the longitudinal plane of symmetry.
Description
[0001] Cross-Referenced Related Applications: This application claims priority from Application No. PCT / RU2006 / 000272 and International Publication No. WO / 2007 / 139420. The earliest priority date is May 26, 2006. [0002] Federally Funded Research: Not available [0003] Sequence listing or program: not available technical field [0004] The claimed invention belongs to the electric power industry. In particular, it relates to improvements in the design of gas discharge reflector lamps for general lighting and special lighting. Background technique [0005] A known gas discharge reflector lamp comprises a burner mounted inside a bulb which has a reflective layer on its inside surface (Soviet Inventor's Certificate No. 1069032, 01.23.84). [0006] The disadvantage of this technical solution is the loss of light flux due to the reflection of part of the light, ie the incident light, from the reflective layer of the elongated burner. Slender burners are common burners for me...
