[0002]
At present, domestic and international metal halide lamps, sodium lamps, and high-power lighting commonly used lamp caps mainly include the standard E40 lamp cap, which has a simple process and low cost, and has been qualified as an international standardized device. It is suitable for lamp products with a maximum voltage of about 8 kV It basically satisfies the use of most existing lamps, but it is not suitable for the hot start requirements of gas discharge lamps. The hot start voltage of many gas discharge lamps exceeds 10,000 volts, and some even reach 20,000-30,000 volts.

Embodiment Construction
[0031] The technical solution will be described in detail below in conjunction with specific embodiments.
[0032] Such as Figure 1-Figure 7 As shown, the present invention is a connection structure between a lamp cap and a lamp holder resistant to ultra-high voltage, including 1 lamp cap and 2 lamp sockets, and 1 lamp cap includes a lamp cap ceramic component 1-1, a lamp cap metal component 1-2 and a lamp cap metal contact piece 1-3. The ceramic assembly of the lamp cap is connected and matched with the metal assembly of the lamp cap. The metal contacts of the lamp cap are fixed on the bottom of the ceramic assembly of the lamp cap; Features. The upper part of the lamp base ceramic assembly is provided with a connection part 1-11 that is connected and matched with the metal spiral assembly, and the bottom of the connection part is provided with a connection terminal 1-12. The width of the connection part is larger than that of the connection terminal, forming Step-like str...

Abstract
The invention discloses an extra-high-voltage-resistant connecting structure of a lamp cap and a lamp holder. The extra-high-voltage-resistant connecting structure comprises the lamp cap and the lamp holder; the extra-high-voltage-resistant connecting structure is characterized in that the lamp cap comprises a lamp cap ceramic assembly, a lamp cap metal assembly and a lamp cap metal contact piece; a concave-convex position is arranged on the bottom side of the lamp cap ceramic assembly; the lamp holder comprises a ceramic lamp holder main body with a built-in cavity used for mounting the lamp cap, a screw thread metal sleeve, a metal contact piece, a lamp holder wiring terminal I and a lamp holder wiring terminal II; an inner ring convex ring and an outer ring convex ring are arranged at the bottom of the cavity of the ceramic lamp holder main body; and a slot position is arranged between the inner ring convex ring and the outer ring convex ring, and matched with the concave-convex position of the lamp cap ceramic assembly in a concave-convex manner. The extra-high-voltage-resistant connecting structure is simple in structure, resistant to high voltage, and stable in performance.
Description
technical field [0001] The invention relates to the technical field of lighting, and more specifically relates to a connection structure between a high-pressure lamp cap and a lamp socket. Background technique [0002] At present, domestic and international metal halide lamps, sodium lamps, and high-power lighting commonly used lamp caps mainly include the standard E40 lamp cap, which has a simple process and low cost, and has been qualified as an international standardized device. It is suitable for lamp products with a maximum voltage of about 8 kV The use basically satisfies the use of most existing lamps, but it is not suitable for the hot start requirements of gas discharge lamps. The hot start voltage of many gas discharge lamps exceeds 10,000 volts, and some even reach 20,000-30,000 volts. Especially the latest generation of energy-saving xenon metal halide lamps. This kind of light source has long life, high luminous efficiency, good color rendering, and hot start wi...
