Problems solved by technology

[0004] However, in the above technical solution, a jumper is added to the high-pressure sodium lamp, and the addition of the jumper makes the structure of the double-ended lamp very complicated, resulting in more solder joints on the high-pressure sodium lamp, and the metal coil wound on the arc tube is easy to move, and solder joints are prone to appear. In the case of looseness leading to failure of the take-off device, the stability of the high-pressure sodium lamp is poor

Abstract

The invention discloses a double-end high-pressure sodium lamp, and relates to the field of high-pressure sodium lamps. The double-end high-pressure sodium lamp is characterized in that metal wires are printed on the outer wall of an electric arc tube, and comprise a longitudinal metal wire and a transverse metal wire, the transverse metal wire extends to the end portion of the tube, the electricarc tube is provided with a starting assisting ceramic chip which is fixed at the end portion of the electric arc tube through a fixing sheet, the starting assisting ceramic chip is a ceramic chip, the starting assisting ceramic chip is coated with a metal coating, and one surface, provided with the metal coating, of the starting assisting ceramic chip is is in contact with the ceramic tube end portion of the electric arc tube, so that welding spots on the electric arc tube and loosening of the welding spots are reduced, and the stability of the high pressure sodium lamp is improved.

Description

technical field [0001] The invention relates to the field of high-pressure sodium lamps, more specifically, it relates to a double-ended high-pressure sodium lamp. Background technique [0002] Double-ended high-pressure sodium lamps have the advantages of high luminous efficiency, compact structure, wide light-emitting area, long life, and no insects, making them widely used in the field of indoor plant lighting. In order to achieve better lighting effects and longer use of high-pressure sodium lamps The life of the arc tube will be filled with a buffer gas with a higher pressure. However, under certain external conditions, the higher the pressure of the buffer gas, the bulb needs an external circuit to provide a higher pulse high voltage to light. In actual use In some cases, high-performance high-pressure sodium lamps may be difficult to start or even impossible to start on some ballasts. [0003] The Chinese patent with the notification number CN209591976U discloses a d...
