A light emitting apparatus has a light emitting element with an emission wavelength in the range of 360 to 550 nm and a rare-earth element doped oxide nitride phosphor or cerium ion doped lanthanum silicon nitride phosphor. Part of light radiated from the light emitting element is wavelength-converted by the phosphor. The light emitting apparatus radiates white light generated by a mixture of the wavelength-converted light and the other part of light radiated from the light emitting element.

Light emitting apparatus and light emitting method

A light-emitting device with an emission wavelength range of from 360 nm to 550 nm and a fluorescent material made of Ca&#x2014;Al&#x2014;Si&#x2014;O&#x2014;N oxynitride activated with Euare used so that a part of light emitted from the light-emitting device is emitted while the wavelength of the part of light is converted by the fluorescent material.

Light-emitting unit having specific fluorescent material

It is an object of the present invention to increase durability of a driving tool. A representative driving tool comprises an elongated operating member that drives in a driving material and a drive mechanism that drives the operating member. The drive mechanism comprises a rotating flywheel and the flywheel includes an inner wheel and an outer wheel which are concentrically disposed to each other. The inner circumferential surface of the outer wheel is fitted on an outer circumferential surface of the inner wheel. The outer circumferential surface of the outer wheel directly contacts the operating member and thus, the rotational force of the flywheel is transmitted from the inner wheel to the operating member via the outer wheel and the drive mechanism linearly moves. A frictional force between the outer circumferential surface of the inner wheel and the inner circumferential surface of the outer wheel is set to be smaller than a frictional force between the outer circumferential surface of the outer wheel and the operating member. With such construction, when the operating member contacts the rotating flywheel, slippage is caused between the inner wheel and the outer wheel such that only a smaller frictional force may be produced between the inner wheel and the outer wheel. Therefore, stress which acts upon the inner wheel and the outer wheel can be alleviated and as a result, wear of the flywheel and the operating member can be reduced to increase the durability.

Driving tool having a two-part flywheel

The present invention provides a lamp that includes a reflection case and a light emitting element. A central portion of a lower wall inner face of the reflection case is stepwise lowered to form a lower wall enlarged inner face, and both faces are made continuous with each other through right and left perpendicular hanging inner faces, so that a central portion of a back wall inner face and a front opening are downwardly enlarged in a rectangular shape, respectively. The light emitting element is mounted on a front face of a sub mount table. A back face of the sub mount table is fixed to the central portion of the back wall inner face, and right and left end faces of the sub mount table are positioned to right and left perpendicular hanging inner faces when the sub mount table is fixed.

A novel configuration of a light-emitting apparatus that can emit white light, in which a primary light source composed of a group III nitride compound semiconductor is used in combination with a secondary light source including a fluorescent material which emits light of a green luminescent color when the fluorescent material is excited by light emitted from the primary light source. A tertiary light source for emitting red light may be further used in combination with the primary and secondary light sources.

Light-emitting apparatus

A light emitting device, free from change of color even when the wavelength of a light emitting element shifts, includes a light emitting element () for emitting primary light having an intensity peak at a wavelength shorter than 400 nm; a silicone resin () provided to embed the light emitting element; and a fluorescent element () contained in the silicone resin to absorb the primary light and release visible light.

Light emitting device

A light source device has a light shielding member having an aperture, a light source arranged on one side of the light shielding member, and a converging member arranged relatively with respect to the light source and the light source to thereby converge light emitted from the light source in the aperture or in a vicinity of the aperture. Another type of light source device has a single light source, and a converging member for converging light from the light source to thereby distribute the light to at least two points. Still another type of light source device has a light source, and a reflecting mirror arranged to enclose a side of a light emission direction of the light source, the reflecting mirror reflecting light emitted from the light source in a direction except the light source so that the light is radiated outside.

Light source device

In a light emitting diode, a blue light emitting element is mounted on a base having a cup through a phosphor-containing mount so that the light emitting element is located within the cup and is mounted on the bottom of the cup through the phosphor-containing mount. The light emitting diode includes a light emitting element and a p electrode. By virtue of the above construction, blue light emitted from the light emitting element can be reflected from the lower surface of the p electrode without being radiated directly from the upper surface of the light emitting element to the outside of the light emitting diode. As a result, the blue light emitted from the light emitting element can be efficiently mixed with yellow light given off from the phosphor in the phosphor-containing mount to provide white light which is radiated to the outside of the light emitting diode with high efficiency. The white light can be perceived by a viewer to be uniformly radiated from the light radiating surface of the light emitting diode.

Light emitting diode

A light-emitting diode includes a light-emitting element, a lead assembly for supplying electrical power to the light-emitting element. A reflection mirror is provided in an opposing relation to the light-emitting surface of the light-emitting element. A light-transmissible material seals the light-emitting element, a part of the lead assembly, and the reflection mirror. A radiation surface radiates light reflected on the reflection mirror to the outside. The reflection mirror is a metal mirror which is obtained by processing a metal plate to give it a concave shape or which is obtained by mirror-surface-treating the concave surface of the metal mirror formed by the processing of the metal plate. The radiation surface is formed on the light-transmissible material at its surface at the rear of the light-emitting element.

Reciprocating cutting tools () may include a drive source () for reciprocally driving a blade (B). The drive source may also drive a blower () in order to generate an air stream.

Further, a chip collector nozzle () may draw or suction cutting chips away from the workpiece that has been cut by the blade.
