    Abstract: PROBLEM TO BE SOLVED: To generate light provided with a smooth spectral distribution in a visible light range so as to improve a color rendering property index by using a sulfur element, a selenium element, or a compound consisting of these elements as a filler of a lamp covered body, impressing electromagnetic radiation to a bulb so as to turn the filler into a plasma condition, and generating light by means of molecular radiation. SOLUTION: A lamp device 2, which is an electrodes lamp, is driven by means of microwave energy, and a filler inside the electrodless bulb (covered body) 3 contains a sulfur element, a selenium element, or one compound consisting of these elements. When the filler inside the non-electrode bulb 3 is excited by means of microwave energy so as to be turned into a plasma condition, light is generated by means of the filler so as to be taken out to the outside of a cavity via a mesh 5. In this way, light radiation dependent on molecular radiation inside a visible light area can be carried out and spectral luminous efficiency can be improved, while a small size high power light source emitting visible light can be accomplished.

    Abstract: An improved structure for a microwave generated plasma light source for emitting radiation in the ultraviolet and visible portions of the spectrum. Microwave energy generated by a microwave source is coupled to a plasma forming medium which is confined in a longitudinally extending tube. The tube is surrounded along its length by a microwave chamber, a portion of which comprises a means for reflecting the emitted radiation and a portion of which comprises a mesh-like member which is substantially transparent to the emitted radiation, but which is relatively opaque to the microwave energy. The microwave energy may be fed to the microwave chamber either from the end thereof, or from the top or sides if the microwave sources is housed in a waveguide located on the top or sides of the chamber. The plasma forming medium is confined at a relatively high pressure and the microwave energy is coupled thereto at a high enough power density to create electron densities in the plasma in excess of the cutoff density. Electrons are excited by the transformation of waves and wave absorption and collide with the heavy particles of the plasma which emit ultraviolet and visible radiation upon de-excitation.

    Abstract: A surface discharge excimer light source which employs a one sided cell wherein all electrodes and the dielectric are on one side of the discharge space. The light produced by the device is neither shadowed nor attenuated by an electrode, and the electrode temperatures can be closely controlled. The construction of the device eliminates the need to maintain parallelism of the discharge space and close tolerances.

    Abstract: process for aligning an optical fibre within a hardening system, which has a lamp for irradiating a radiation-hardenable polymer coating on the fibre and in which part of the hardening radiation is coupled into the fibre, involves (i) decoupling part of the coupled radiation from the fibre; (ii) measuring the intensity of the decoupled radiation; and (iii) altering the relative positions of the coated fibre and the hardening system until the desired decoupled radiation intensity is obtd. Pref. the radiation is UV radiation of 250-400 nm, wavelength. The desired intensity is the max. attainable intensity. The fibre is aligned during linear movement through the hardening system, the fibre position relative to the hardening system being altered by changing the position of one or more optical elements, changing the position or the angular orientation of the hardening lamp, or adjusting the fibre position. ADVANTAGE - The process provides improved alignment of the fibre at the focal point of the optical system to achieve max. intensity of radiation incident on the fibre.

    Abstract: An improved bulb mounting arrangement for an electrodeless lamp to prevent the bulb from rotating during lamp operation. The shape of the bulb mounting projection ends and the shape of the cavity side wall openings are arranged so as to cooperate with each other to preclude substantial rotation of the bulb.
