  • Patent number: 9428689
    Abstract: A solid light-emitting device comprising a light-emitting semiconductor element and a phosphor dispersed in a sealant, in which the phosphor is exited by the light emitted by the semiconductor element to emit a visible light of a wavelength differing from that of the light emitted by the semiconductor element and is a silicate phosphor or a phosphor having a hydroxyl group on its surface, and the sealant is a condensation product of a prepolymer produced by condensation of polydimethyl-siloxane having a silanol group at both ends and an oligomer of an alkoxide of a metal or a semimetal or its derivative.

  • Patent number: 6316844
    Abstract: A standby power supply circuit with a low power consumption including: a voltage converter for rectifying a commercially used AC power source to convert it to a DC voltage; a standby power supplier for receiving the DC voltage from the voltage converter; a voltage comparator for comparing the DC voltage outputted from the voltage converter with pre-set reference voltages and outputting a predetermined pulse signal; and a switch unit for ON/OFF controlling the operation of the voltage converter according to a pulse signal outputted from the voltage comparator. With the construction, a zero cross switch is intermittently turned on or turned off, so that the standby transformer is turned on or turned off, by which the standby power can be reduced when the electric instruments are in a standby state.

  • Patent number: 5955848
    Abstract: A horizontal S-shaped correction signal circuit having a correction condenser disposed in a cathode ray tube (CRT) horizontal deflection circuit such as in a television receiver, a display monitor, etc. In particular, a horizontal S-shaped correction signal circuit which is capable of obtaining an accurate correction effect and a desired adjustment. The total capacitance of the correction condenser C.sub.S for a horizontal deflection circuit is variable by selectively connecting in parallel therewith correction condensers C.sub.S1 and C.sub.S2 by switches SW.sub.1 and SW.sub.2 during the scanning interval. Therefore, the correction characteristic is improved. Namely, it is possible to obtain a highly accurate S-shaped correction signal. In addition, it is possible to independently control the width of the front portion and rear portion of the horizontal scanning interval by controlling externally inputted direct control current signals DA-C.sub.TL1 and DA-C.sub.TL2.

  • Patent number: 4733335
    Abstract: A vehicular lamp employing light-emitting diodes providing a good illumination efficiency, and which can be readily mounted on many different types of vehicles. The lamp includes a plurality of light-emitting diodes arranged on a supporting board, condenser lenses provided in front of each of the light-emitting diodes, and diffusion lenses arranged in front of the condenser lenses. A housing member supports the supporting board, the condenser lenses, and the diffusion lenses, the housing member having air holes formed therein to provide for ventilation. With this arrangement, the light produced by the light-emitting diodes is applied in the form of parallel beams to the front lens member by the condenser lenses, and the parallel light beams are diffused by the diffusion lenses on the front lens member. Accordingly, the front surface of the front lens member is illuminated in its entirety and illuminated uniformly.

  • Patent number: 4722023
    Abstract: A lamp assembly is disclosed as adapted for use as a supplemental high mounted stop lamp for motor vehicles. A lamp body has a paraboloidal reflector for producing parallel rays of light from a source mounted therein. For reducing the axial dimension of the lamp body to a minimum, a generally planar lens is mounted at its open front end, with the lens having a multiplicity of prism elements formed on its outer surface for internally reflecting the parallel rays in a direction at a considerable angle to the axis of the reflector. Additional embodiments are disclosed for imparting both lateral and vertical divergence to the light beam emitted, and for producing two vertically overlapping light beams.

  • Patent number: 4652979
    Abstract: A lamp assembly is disclosed as adapted for use as a supplemental high mounted stop lamp to be installed just interiorly of a steeply slanting rear window of a motor vehicle. A lamp housing has a light source disposed therein, and two generally planar lens members are mounted at the open front end of the lamp housing in parallel spaced relation to each other. The inner lens member is configured to provide a Fresnel lens effective to render the light rays from the source parallel to the principal axis of the lamp assembly, thereby superseding the paraboloidal reflector heretofore employed to the same end. The outer lens member has a plurality of prismatic lens segments for internally reflecting the parallel rays from the inner lens member in a predetermined direction at a considerable angle to the lamp assembly axis. Preferably, the two lens members are further so molded as to impart both lateral and vertical divergence to the light beam emitted by the lamp assembly.
