Definitions

• the alleged invention relates to the electrical industry, in particular, improves the design of discharge lamps for general and special lighting.
• the disadvantage of the technical solution taken as an analogue is the loss of the luminous flux of lamps due to the fall of a part of the reflected rays from the mirror layer onto an extended burner, which is usually a mercury, metal halide and sodium lamp, impossibility to obtain different light intensity curves in the longitudinal and transverse planes , which greatly reduces the operational characteristics of the lamps.
• the closest in technical essence is a gas-discharge mirror lamp containing a burner mounted on the current leads into the bulb, at least half of the inner surface, which is coated with a mirror layer so that the plane passing through its longitudinal edges is parallel to the longitudinal axis of the burner (A.S. USSR , N ⁇ > 1636896 Al, 03.23.91).
• This technical solution taken as a prototype, allows to obtain lamps with high light output, with different light intensity curves in the longitudinal and transverse planes, which is important when using lamps to illuminate roads, greenhouses, etc.
• the disadvantage of the prototype is the high cost of the lamp due to the complexity of manufacturing non-axisymmetric flasks, the uneven wall thickness of the flasks due to the inability to rotate the injection molds during bulb production, and there is a high probability of voltage in the glass when the lamp is operating.
• the objective of the invention is to reduce the cost of gas discharge mirror lamps and improve its quality.
• the task is achieved by the fact that in a gas discharge mirror lamp

Arrows indicate incident and reflected rays.
• Placing a plane passing through the longitudinal edges of the mirror layer from the axis of the bulb at a distance of more than 0.011 of the maximum diameter of the bulb D increases the proportion of radiation after multiple reflections and reduces the luminous flux of the lamp.
