20140159607 | LIGHTING APPARATUS AND CONTROL CIRCUIT - 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. | 06-12-2014 |
20130033874 | LIGHT-EMITTING APPARATUS AND LIGHTING SYSTEM - 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. | 02-07-2013 |
20110019293 | DRIVER, LENS DRIVER AND MECHANICAL APPARATUS - 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. | 01-27-2011 |
