Power supply connecting device of double-end gas discharge lamp

Abstract

The invention discloses a power supply connecting device of a double-end gas discharge lamp. The connecting device comprises a molybdenum piece used for fixing a squashing hermetic seal section on the two ends of a lamp tube, and the molybdenum piece is respectively connected with a molybdenum rod and an educing wire; the educing wire is clamped among clamping pieces so as to form an outgoing line clamping piece, a porcelain head is respectively fixed on the squashing hermetic seal sections on the two ends of the lamp tube, and the outgoing line clamping piece is fixed on the porcelain head; an integral outgoing line clamping piece is directly inserted in a power socket, the contact surface is large, the electric property is good, the mechanical strength is high, thereby greatly reducing an exothermic phenomenon; the other end of the outgoing line clamping piece is arranged in an insulation porcelain head which is heat-resisting moisture-proof and high dielectric strength, and a groove is arranged in the porcelain head and matched with the squashing hermetic seal section on the two ends of the lamp tube; and the glass part is not easy to crack, the service life of the discharge lamp is greatly prolonged, defects that the original power supply connecting device is easy to heat and transform, and the glass is easy to crack are improved, and the use is safe and reliable.

Description

technical field [0001] The invention relates to a connection between a gas discharge lamp and a power supply, in particular to a power supply connection device for a double-ended gas discharge lamp. Background technique [0002] Patent No. CN201020273628.6 "High Power Gas Discharge Lamp for Plant Lighting" is connected to the power supply with the thread on the lamp head end. Although it is convenient to use, the working temperature of the gas discharge lamp is high. After working for a long time, the lamp head is easy to heat up and become black and loose , which is not safe to use. [0003] Patent No. CN201020271581.X "Double-ended high-power high-pressure sodium lamp" also discloses a connection device with the power supply. The two ends of the light source are connected to the molybdenum rods, and the molybdenum sheets are arranged at the two ends of the glass bulb at the flattened air-tight joints. They are respectively connected to molybdenum rods and lead wires made ...

[0002] Patent No. CN201020273628.6 "High Power Gas Discharge Lamp for Plant Lighting" is connected to the power supply with the thread on the lamp head end. Although it is convenient to use, the working temperature of the gas discharge lamp is high. After working for a long time, the lamp head is easy to heat up and become black and loose , it is not safe to use

[0003] Patent No. CN201020271581.X "Double-ended high-power high-pressure sodium lamp" also discloses a connection device with the power supply. The two ends of the light source are connected to the molybdenum rods, and the molybdenum sheets are arranged at the two ends of the glass bulb at the flattened air-tight joints. They are respectively connected to molybdenum rods and lead wires made of multi-strand metal guide wires. Because the flattened airtight joint connected to the power supply is a glass part with low thermal conductivity and low mechanical strength, the glass at the end is easily broken after long-term high-temperature operation. , directly connected to the power supply with lead wires, the contact surface of a single bundle of wires is small, the capacitance is small, easy to loose, easy to break, easy to deform, unreliable connection, and unsafe to use
