摘要:
A metal halide lamp comprises a discharge container including a discharge space and a pair of sealing sections. A discharge medium containing a metal halide and a rare gas and essentially free from mercury is sealed in the discharge container. A pair of electrodes are arranged to face each other within the discharge space, and the side edge portions on the side of the proximal end portion of these electrodes are held by the sealing sections. The amount of water contained in the metal halide, i.e., the light-emitting material, included in the metal halide lamp essentially free from mercury, i.e., Hg-less metal halide lamp, is controlled to 50 ppm or less.

An illuminating device that is improved in heat radiation property and is suppressed in the occurrence of peeling and warping of a reflector. The reflector having a housing portion that houses a light emitting diode element is disposed on a substrate a visible light converting layer is formed on the housing portion and a lens is disposed on the reflector. A circuit pattern, the light emitting diode element, the reflector, the visible light converting layer, and the lens are disposed on the substrate, and the reflector and the lens are respectively adhered using a same type of adhesive agent. The heat radiation property can thus be improved, the peeling and warping of the reflector, etc., is suppressed, and accordingly, the optical characteristics of the device can be maintained.
