Abstract
The utility model discloses a xenon lamp capable of preventing bad arc discharge, comprising an outer bulb, an inner bulb and a lamp head, wherein a seal port is arranged at the end of the outer bulb and two electrode conductors of the inner bulb pass through the seal port to be connected with the lamp head and one electrode conductor of the inner bulb is sleeved with a quartz glass cell, characterized in that: one end of the quartz glass cell is fixed in the seal port and a molybdenum slice is sleeved outside the electrode conductor in the seal port. The xenon lamp effectively prevents the bad arc discharge between two electrodes of the xenon lamp and has features of long service life, safety, practicability, efficiency and energy saving.
Description
Technical field
The utility model relates to lighting technical field, relates to a kind of xenon lamp in particular.
Background technology
HID is exactly the english abbreviation of High intensity Discharge high-voltage gas discharging light, can be described as heavy metal lamp or xenon lamp.Its principle is in the quartzy quartz glass tube of UV-cut uvioresistant, with the number of chemical gas filling, wherein major part is inert gases such as xenon (Xenon) and iodide, and then see through booster (Ballast) direct voltage moment of 12 volts on the car is pressurized to 23000 volts electric current, excite the xenon electronics in the quartz ampoule free through the high pressure amplitude of vibration, between two electrodes, produce light source, Here it is so-called gas discharge.And, can improve the light color temperature value by the white superpower arclight that xenon produced, and the sunshine in similar daytime, the required magnitude of current only is 3.5A during HID work, and brightness is three times of traditional based on halogen bulb, and useful life is than long 10 times of traditional based on halogen bulb.But when starting owing to xenon lamp, voltage is more than 20000V, be easy between two electrodes of xenon lamp to produce arc discharge, it is common spark phenomenon, make the fluorescent tube can't operate as normal, and, under high temperature and high pressure environment, be easy to occur the arc discharge phenomenon between negative electrode and the anode for the HID xenon lamp that adopts single-ended Metal halogen lamp structure, thereby the HID xenon lamp is caused damage, influence the useful life of fluorescent tube.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, effective, and the xenon lamp of the anti-bad arc discharge of safety and stability.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of xenon lamp of anti-bad arc discharge, comprise Wai Pao, interior bubble and lamp holder, the end of outer bubble is provided with clamp opening, two contact conductors of interior bubble pass clamp opening and are connected with lamp holder, a wherein contact conductor of interior bubble is socketed with the quartz glass pipe box, it is characterized in that, one end of described quartz glass pipe box is fixed in the clamp opening, the contact conductor that is positioned at the clamp opening section is connected to the molybdenum sheet transition, make clamp after thermal expansion air tight.
As further specifying of such scheme, described quartz glass pipe box is an one with the end clamp of outer bubble.
Described lamp holder is provided with two lamp bases, and two contact conductors of interior bubble are connected on two lamp bases.
The top of described outer bubble is provided with the location division, and an electrode of interior bubble is provided with support bar and is fixed on the location division.
Described lamp holder is a base of ceramic, and the upper end of base of ceramic is provided with and the corresponding caulking groove of outer bubble clamp end.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The end of the utility model adopting quartz glass pipe box and outer bubble is clamp simultaneously, and the electrode in clamp opening connects the molybdenum sheet transition and prevent to overflow and leak, and effectively prevents to jump when two electrodes start in the bubble arc sparking, and high-pressure leakage when preventing to start improves the stability of HID xenon lamp.
