A light module 1 includes a planar light emitting device 2, a wiring board 3, and an optical sheet 4. The wiring board 3 has a hole 8 for accommodating the planar light emitting device 2. The optical sheet 4 holds the planar light emitting device 2 and the wiring board 3 such that the planar light emitting device 2 accommodated in the hole 8 of the wiring board 3 and the wiring board 3 are flush with each other on the light emitting surface side of the light module 1. The optical sheet 4 holds the planar light emitting device 2 and the wiring board 3, and prevents dust and moisture from entering the inside the light module 1. This eliminates the necessity for the light module 1 to include a casing, packing, and the like. Therefore, the thickness of the module can be reduced.

A light emitting module includes an organic EL light emitting element and a support body supporting the organic EL light emitting element. The support body is attached to the organic EL light emitting element at the side of the non-light emitting surface of the light emitting module to cover one surface of the organic EL light emitting element. The organic EL light emitting element includes power feeding electrodes. The support body includes openings formed in a corresponding relationship with the power feeding electrodes. The power feeding electrodes exposed on the non-light emitting side of the support body through the openings. The support body includes power feeding terminals. The power feeding terminals partially exposed on the non-light emitting side of the support body. The power feeding terminals electrically connected to the power feeding electrodes by electric connection members extending via the non-light emitting side and the openings of the support body.

A discharge lamp lighting device includes: a DC power source; an inverter for inverting the DC power at a predetermined inversion time interval to supply a square wave AC power to a discharge lamp; and a controller for controlling the output power. The controller performs a synchronous operation and controls the DC power source such that DC power outputted during a period other than the output temporarily increasing period in a power increasing period is greater than the DC output power outputted during the period other than the output temporarily increasing period in a rated power period. Further, the controller controls the DC power source such that at least one of an increment of the output power for the output temporarily increasing period and a length of the output temporarily increasing period is less in at least a part of the output increasing period than in the rated power period.

An electrodeless low pressure discharge lamp comprises an envelope made from a straight tube and a reentry cavity sealed to one of tube's ends. The cavity has several hollow ferrite cores separated from each other with a few mm distance. Each ferrite core has an induction coil of few turns wound around the core. Each cavity has a cooling copper tube or rod located inside the ferrite core that removes heat from the cores and dumps the heat into a heat sink welded to the cooling tube/rod thereby keep the temperature of the ferrite cores below their Curie point. Each induction coil is electrically connected to the matching network while all matching networks are connected in parallel to the high frequency power source (driver). Inductively coupled plasmas generated in the envelope by several core/coil assemblies produce axially uniform UV and visible radiation.

A light emitting module has a flat light emitting panel including a transparent substrate and a light emitting part formed on the substrate. The flat light panel includes: electrode pads which are formed on the substrate outward of the light emitting part and are electrically connected to the light emitting part; and a transparent or light reflective sealing member which is provided to cover the electrode pad.

A lamp ballast for operating a high intensity discharge lamp includes an electronic ballast circuit to supply an operating voltage to the discharge lamp, and an igniter circuit to supply starting pulses to the discharge lamp in a cold state and to supply hot restrike pulses to the discharge lamp when the discharge lamp is in a hot state following turn-off. The hot restrike pulses are sufficient to maintain ionization in the discharge lamp but do not cause the discharge lamp to generate substantial light output.

An arc discharge metal halide lamp having a discharge chamber having visible light permeable walls bounding a discharge region supported electrodes in a discharge region spaced apart by a distance Le with an average interior diameter equal to D so they have a selected ratio. Ionizable materials are provided in this chamber involving a noble gas, one or more halides, and mercury in an amount sufficiently small so as to result in a relatively low maximum voltage drop between the electrodes during lamp operation.

An arc tube is provided for use in a high intensity discharge lamp. The arc tube is generally comprised of an elongated outer envelope defining two opposed ends and a cavity therebetween; an electrode sleeve protruding outwardly from each end of the outer envelope, such that each electrode sleeve has a passageway; and an electrical feedthrough member inserted into the passageway of the electrode sleeve, where the feedthrough member includes an inner rod that extends into the cavity of the arc tube and a ceramic sleeve encircling a portion of the inner rod disposed within the passageway. A sealing compound is disposed at an outwardly facing end of the passageway for sealing the feedthrough member to the electrode sleeve, such that the sealing compound extends into the passageway of the electrode sleeve but is spatially separated from the ceramic sleeve.
