An LED lamp provides a strong red color with a natural appearance. The LED lamp is provided with an LED module and a filter. The LED module includes a blue LED with a main emission peak in the 440 nm to 460 nm wavelength band, a green/yellow phosphor that is excited by light emitted by the blue LED, and a red phosphor that is excited by light emitted by at least one of the blue LED and the green/yellow phosphor. The filter reduces the spectral radiation intensity of at least a portion of the 570 nm to 590 nm wavelength band among light emitted by the LED module.

LED lamp, LED illumination device, and LED module

An illumination device includes an image element configured to convert light incident thereon to image light and to output the image light, a first light path extending to pass through the image element, and a second light path extending without passing through the image element. The first light path and the second light path are configured to project lights passing therethrough, respectively, on an object existing outside the illumination device.

Illumination device

A wavelength conversion member includes a substrate, a dichroic mirror layer, an SiOlayer, a ZnO layer, and a phosphor layer, which are sequentially stacked from the substrate. The dichroic mirror layer reflects at least part of light incident from the above. The phosphor layer includes a plurality of phosphors and ZnO between the phosphors.

Wavelength conversion member, light emitting device, projector, and method of manufacturing wavelength conversion member

An illumination apparatus includes a first unit, a second unit, and a third unit. The first unit includes an excitation light source that produces excitation light. The second unit includes a light-for-illumination phosphor. The light-for-illumination phosphor produces and outputs light for illumination when the light-for-illumination phosphor receives excitation light. Furthermore, the second unit produces and outputs light for projection. The light for illumination and the light for projection are outputted in a time division manner. The third unit includes a light shaping member. The third unit shapes the light for illumination by the light shaping member and guides the shaped light for illumination to the outside as illumination light, and shapes the light for projection by the light shaping member and guides the shaped light for projection to the outside as projection light.

Illumination apparatus

An illumination apparatus includes: an illumination light setter which sets illumination light for illuminating an illumination area which includes at least one of a space or an object; an image light setter which sets image light for projecting a projection image which includes at least one of a graphic or a character; and a light projector which emits the illumination light set by the illumination light setter, and projects the image light set by the image light setter.

Illumination apparatus with image projection

A lighting apparatus is provided capable of emitting light for image projection and light for illumination at the same time. The lighting apparatus includes: an imaging element that converts incident light into light corresponding to an image and outputs the light; a projection lens through which the light is projected onto an object; a first optical path taken by light that is emitted from the projection lens via the imaging element; and a second optical path taken by light that is emitted without passing through the imaging element and the projection lens.

Lighting apparatus

A lighting apparatus includes a plurality of LEDs arranged in a row; an elongated wiring board on which the LEDs are mounted; and an optical lens covering all the LEDs and controlling distribution of light emitted from each LED. The light emitted from each LED has an optical axis orthogonal to the wiring board. The optical lens is a converging lens and includes a first light incident surface on which the light emitted from the LED is incident, a medium that guides the light incident from the light incident surface, a light emitting surface, and a diffusion section that contains diffusing particles for causing the light incident from the LED to diffuse. The concentration of the diffusing particles in the diffusion section is high in the vicinity of the optical axis of the light emitted from the LED and gradually decreases as a distance from the optical axis increases.

A light source device and a projection type display apparatus include: an excitation light source; and a fluorescence light-emitting plate including a fluorescence light-emitting section arranged opposite to the excitation light source and a reflection section containing titanium oxide located on the opposite side of the excitation light source as viewed from the side of the fluorescence light-emitting section and arranged such as to be joined to the fluorescence light-emitting section. Then, excitation light from the excitation light source is projected onto the fluorescence light-emitting section so that fluorescence emission light is emitted from the fluorescence light-emitting section and reflected fluorescence light is emitted from the reflection section.

Light source device and projection type display apparatus employing same light source device

A lighting system includes a lighting apparatus provided along one side of an aisle and a specular reflection plate provided along the other side of the aisle to reflect the light emitted from the lighting apparatus toward a region where the lighting apparatus is provided. According to the above configuration, the lighting apparatus can illuminate the region where the lighting apparatus is provided. Therefore, it is possible to effectively illuminate a cabin of an aircraft with less lighting apparatuses as compared to conventional lighting apparatuses which are provided along both sides of the aisle. Moreover, since the number of the lighting apparatuses can be reduced, it is possible to improve fuel efficiency of the aircraft by reducing the total weight of the aircraft.

Lighting system

An illumination light source includes a light emitting module having a light emitting part, a circuit unit, a base, a tube-like first housing member to accommodate the circuit unit, and a second housing member having a plurality of radiation fins. The light emitting module is disposed on one opening-side of the first housing member, while the base is disposed on the other opening-side. The second housing member includes a rotary ring body with a rotation axis agreeing with the center axis of the first housing member, and the plurality of the plate-lake radiation fins. The plurality of the radiation fins is parallel to one virtual plane containing the rotation axis, and disposed at intervals between each other in the direction orthogonal to the virtual plane. The inner wall of the rotary ring body surrounds the outer walls of the first and second housing members to combine the members.

Illumination light source

This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced.

To constrain reductions in luminous efficacy while enhancing the color rendition index, the LED module includes a blue LED, at least one variety of phosphor particles excited by the outgoing light from the blue LED, and neodymium glass particles that include neodymium ions absorbing the outgoing light from the phosphor particles in a predetermined wavelength band.

An object of the present invention is to provide a mounting substrate, a manufacturing method, a light-emitting module and an illumination device that can sufficiently improve the luminous efficiency of an LED lamp.
