Abstract: A light emitting device includes: an LED; a reflecting mirror that reflects light emitted by the LED and radiates the light outside and has a reflecting surface shaped in a paraboloid of revolution; and a light absorptive material that, of the light emitted by the LED, blocks the light beyond a 1/4 beam angle ? from being incident on the reflecting mirror. The LED is provided at a position displaced from a focal point of the paraboloid of revolution.

Abstract: A light-emitting apparatus includes a light-emitting diode that functions as a light source, and a teardrop-shaped translucent member formed of a translucent material. The teardrop-shaped translucent member includes a bottom portion via which the light emitted from the light-emitting diode is input, a lateral portion configured to provide total internal reflection of the light input via the bottom portion, and a top portion configured to focus the light subjected to total internal reflection by the lateral portion so as to form an image.

Abstract: A lighting apparatus includes a first LED unit and a second LED unit configured to provide different color temperatures. A pulse/voltage conversion circuit is connected between a power supply line and a low-potential side reference line, and configured to convert the pulses of input electric power into a voltage. A voltage dividing circuit is connected between the output terminal of the pulse/voltage conversion circuit and the low-potential side reference line, and configured to divide the voltage converted by the pulse/voltage conversion circuit. The dividing node of the voltage dividing circuit and the low-potential side terminal of the second LED unit are connected.

Abstract: The size of a driving apparatus to be mounted in a mobile terminal is desired to be reduced. In a driving apparatus according to the present invention, an arm member supports a member to be driven in a slidable manner. A first biasing member has a predetermined spring constant and biases the member to be driven via the arm member. A second biasing member has a spring constant that is smaller than the spring constant of the first biasing member and, by biasing the member to be driven in a direction that goes against the first biasing member, supports the member to be driven along with the arm member. A shape-memory alloy swings the arm member against the first biasing member by contracting when a drive current is supplied. The member to be driven is slid, when the arm member swings, by the second biasing member while keeping contact with the arm member.

Abstract: A light emitting diode includes a light emitting body, a lead frame supplying power to the light emitting body and a light transmitting resin covering the light emitting body and part of the lead frame. The top surface of the light transmitting resin is formed as a plane at a position that satisfies a condition in which part of radiated light from the light emitting body is totally reflected. An inclined surface is formed at a position that satisfies a condition in which part of the radiated light is refracted in a downward direction away from a line perpendicular to the inclined surface.

Abstract: A light-emitting unit containing a substrate and light emitting diodes (LEDs) is housed inside a casing constituted by a first member and a second member which are joined together. The second member has a projecting piece which is inserted to the first member, and inside the projecting piece a passage is formed. When silicone is injected through an injection opening from an injector, the silicone starting from the projecting piece flows through in the order of the passage, first-member side space, connecting passage and second-member side space and it finally overflows from a discharge opening. By implementing this structure and process, the air or air bubbles inside the light-emitting unit is pushed outside completely.
