DEVICE AND METHOD OF STARTING A LONG RADIATION SOURCE

The present invention relates to a method and apparatus for starting and maintaining a long electrical arc in an arc chamber containing a few atmospheres of pressure of an ionizable gas. An electrical potential difference is maintained between two fixed primary electrodes while a short arc is created between the first primary electrode and a pilot electrode, creating ionized gas. The ionized gas is caused to flow towards the second primary electrode thus creating a region of ionized gas between the two primary electrodes, and hence causing a long arc to be struck. This method does not require relative electrode movement as was the case previously. Such long electrical arcs have utility as sources of heat and light, particularly light of high intensity.

DISCHARGE LAMP

It is provided a discharge lamp (10) comprising a burner (14) for emitting light connectable to a socket (12) for mechanical connection to a lighting device, where¬ in the burner (14) comprises a discharge vessel (20) for providing a discharge arc (30), and a reflector (22) arranged adjacent to the coolest area and/or lowest area of the dis- charge vessel (20) during operation. It was found that in the discharge vessel (20) salts (24) may condense to the glass body of the discharge vessel (20), wherein the condensa¬ tion occurs mainly at the coolest area of the discharge vessel (20) during operation.

Sealed beam high intensity discharge lamp system for aircraft

A system for enabling successful use of HID lamps in aircraft, including in particular high power lamps for use as landing lights and taxi lights, utilizes a sealed beam HID lamp which during normal operation has an external temperature considerably lower than the external temperature of a quartz halogen or incandescent sealed beam lamp of equivalent light output. The lower external temperature arises in part from the use of a gas fill in the sealed beam. A detector is provided to monitor the seal integrity of the sealed beam HID lamp and further to provide a response to seal failure resulting in disablement of the lamp. Exemplary means for accomplishing seal failure detection include radioactive detection, pressure monitoring, and chemical sensing, or other means wherein detection of a failed seal is followed by an electrical output used to terminate or preclude lamp operation.

Discharge lamp and method of operation

Miniature high pressure arc lamps containing a substantial pressure of xenon, in addition to metal halide and mercury, can provide instant light at turn-on and are suitable for automotive headlamps. The xenon aggravates convection which causes arc-bowing and overheating of the envelope above the arc. By operating the lamps on unidirectional current upon which a frequency-modulated high frequency ripple has been imposed, acoustic resonance is used to straighten out the arc. The use of unidirectional current permits a reduction in cost and size of the ballast control circuits operated from auto storage battery. Frequency modulation of the ripple broadens the band allowing acoustic straightening of the arc. Additional control of the arc plus reduction of cataphoresis may be achieved through a horizontal magnetic field at the arc, transverse to current flow. ...

Mercury free discharge lamp with zinc iodide

A compact fused silica, electroded HID lamp for automotive forward lighting, which contains no mercury. The lamps voltage, approximately 40 volts, is developed in this lamp by vaporizing zinc iodide instead of mercury. A compromise between voltage and luminous flux is achieved through the choice of the sodium scandium (Na:Sc) molar ratio, between 4.5:1 and 6:1 and a zinc iodide (ZnI 2 ) dose of 2 to 6 micrograms per cubic millimeter that permits the lamp to operate within the North America, European and Japanese automotive color specifications for white light. The voltage in the lamp can be controlled according to the zinc iodide doping level without seriously impacting the visible spectrum otherwise provided by the other known dopants in the lamp.
