摘要:
A light-emitting module includes at least one light-emitting element provided on a mount surface of a substratum. A translucent member is provided so as to face the mount surface of the substratum. The translucent member is separated from the light-emitting element and contains a phosphor material that converts a wavelength of light emitted by the light-emitting element. A frame having heat conducting properties is interposed between the substratum and the translucent member. The frame surrounds the light-emitting element. The frame includes an opening that leads light emitted by the light-emitting element to the translucent member, and a heat conductor thermally connected to the translucent member. The heat conductor includes a heat radiator exposed outside of the translucent member.

The present invention comprises a lighting apparatus main body having a reflecting surface, a main light source arranged in the reflecting surface of the lighting apparatus main body, a sub-light source which is arranged at the lighting apparatus main body and illuminates the neighborhood of the main light source directly, and a control circuit which controls the main light source and the sub-light source. Since the lighting apparatus illuminates downward with a direct illumination of the main light source and an indirect illumination of the sub-light source, the glare of the main light source is reduced.

A lighting device includes a light source configured to radiate light toward a floor from a ceiling, a reflecting mirror provided around the light source, and shading angle setting element configured to define a range in which the light from the light source is radiated by setting a shading angle with respect to the light radiated from the light source. The light source, the reflecting mirror and the shading angle setting element are covered by a translucent cover. The translucent cover has an in-line transmittance. An in-line transmittance of the translucent cover of a position corresponding to an optical axis of the light source and an in-line transmittance of the translucent cover of a position deviated from the optical axis are different from each other.

A lighting fixture includes a light-emitting section composed of a plurality of semiconductor light-emitting devices arranged separated from one another on a planar substrate and a lighting control section configured to control lighting of the semiconductor light-emitting devices of the light-emitting section. The light-emitting section is attached at a front of a fixture main body, and a convection generation section configured to generate convection is provided at a back of the fixture main body. The convection generation section generates convection and promotes heat radiation. With the configuration, even if the lighting fixture is installed to abut on a ceiling surface, the effect of radiating heat generated by the semiconductor light-emitting devices can be ensured.

摘要:
A light emitting device, with which the luminous efficiency is improved and the color non-uniformity of the emitted light is lessened. Specifically, a light emitting diode element is covered with a diffusing layer, with which a diffusing agent is added to a resin. A phosphor layer, with which a phosphor is added to a resin, is disposed on top of the diffusing layer. The light from the light emitting diode element is diffused by the diffusing layer. By exciting the phosphor layer with the light diffused by the diffusing layer and thereby making the phosphor layer emit light, the luminous efficiency is improved and the color non-uniformity is lessened.

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.
