光束低下が無、くなるという利点がある。[Prior Art] Recently, electrodeless discharge lamp devices that discharge and emit light using an electromagnetic field or electromagnetic waves have been developed. The features of this electrodeless discharge lamp device are that unlike light source devices using conventional discharge lamps with electrodes, it has a long lifespan because it does not have electrodes, and also has a blackening phenomenon on the lamp wall due to the scattering of electrode material. This has the advantage that there is no reduction in luminous flux due to

Because the halogen material is sealed inside the lamp, electromagnetic fields and electromagnetic waves are applied from the outside, and even if electrons are generated inside the lamp, they adhere to the halogen material and do not effectively contribute to dielectric breakdown, making it difficult to start.

In the figure, 1 is an electrodeless discharge lamp bulb made of translucent quartz, and inside the lamp bulb 1 is a predetermined amount of mercury, a rare gas, and a metal halide. is included. Reference numeral 2 denotes a starting aid bulb made of translucent quartz, which is filled with a predetermined amount of mercury and a rare gas, and is integrally formed with the lamp bulb 1.

放電に容易に移行する。When an electromagnetic field or electromagnetic wave is applied from the outside to the electrodeless discharge lamp configured in this way, since a halogen substance is sealed inside the lamp bulb 1, electrons will adhere to the halogen substance as described above, causing the insulation to deteriorate. Although it is difficult to break down and difficult to start, since only mercury and rare gas are sealed in the starting aid pulp 2, discharge easily occurs within the starting aid bulb 2, causing mercury to emit light. . The ultraviolet light emitted from this mercury is irradiated into the lamp bulb 1, and the energy of this ultraviolet light excites the lamp bulb 1.
Ionization occurs and easily transitions to a main discharge due to the applied electromagnetic field or electromagnetic waves.

形状は一例であり、形状は限定されない。Note that it is sufficient that a substance that emits light that can optically excite the lamp bulb 1 is sealed in the starting aid bulb 2 . In particular, if a combination such as mercury and argon gas is used that can be expected to have a Penning effect, dielectric breakdown within the starting aid bulb 2 will occur more easily, and the lamp bulb 1 will start the main discharge after applying an electromagnetic field or electromagnetic wave. It is even more effective in shortening the time it takes to migrate. Further, in the embodiment described above, only one starting assist valve 2 is provided, but it goes without saying that a plurality of starting assist valves 2 may be provided. Further, the shapes of the lamp bulb 1 and the starting aid bulb 2 in the above embodiments are merely examples, and the shapes are not limited.
