A light-emitting device (10) using an LED is proposed. This light-emitting device (10) is provided with a packaging substrate (1), a light-emitting element (2) which is mounted on this packaging substrate (1) with its face down, a fluorescent member (3) that is arranged face to face with a light-extracting surface (S) of the light-emitting element (2) without contacting the light-emitting element (2) and an optical member (4) which receives light that has been emitted from the light-emitting element (2) and made incident thereon through the fluorescent member (3), and aligns the incident light toward the outside of the device. Light, emitted from the light-emitting element (2), is made incident on the fluorescent member (3) to excite the fluorescent material so that the fluorescent material re-emits light having a wavelength different from that of the incident light. Those light rays, emitted from the light-emitting element (2), which have not been absorbed by the fluorescent member (3) and have passed through the fluorescent member (3) and those light rays that have been emitted from the fluorescent material are made incident on the optical member (4) and are aligned. Because the fluorescent member (3) is not made in contact with the light-emitting element (2), it does not receive the heat from the light-emitting element (2) through heat conduction, and consequently becomes less susceptible to degradation due to heat. Moreover, with the face-down mounting structure, the fluorescent member (3) and the optical member (4) can be placed closer to the light-emitting element (2) as long as they dose not contact the light-emitting element (2). Consequently, the service life of the fluorescent material or the fluorescent-material-mixed resin that tends to deteriorate can be lengthened, lights can be extracted more efficiently, and light rays can be properly aligned in a predetermined direction.

In the case that the LED is used as a light source for a backlight such as a display unit or the like, if a lot of current is circulated for securing a brightness, a lot of heat is generated in view of a characteristic of the LED, so that the LED comes to a high temperature, and there is a problem that the characteristic of the LED itself is deteriorated such as a light output is lowered, a long-term service life can not secured, or the like. Further, in the case that a temperature difference exists between a plurality of LEDs, there is a problem that it appears as a brightness irregularity of a screen of the display unit. The display unit is provided with a heat sink attached so as to be thermally contacted with an opposite side to an LED mounting surface of a substrate on which the LEDs are mounted, and one or a plurality of fans, a base portion of the heat sink has a substrate mounting surface and a fin constituting surface, the fin constituting surface is approximately perpendicular to the substrate mounting surface, and the fin constituting surface of the base portion and an air supply and exhaust surface of a cooling air are formed in an opposite side to a screen display side of the display.

An electrical cable connector having a voltage detection test point generally includes an internal conductor, an inner insulating sheath surrounding the conductor, a conductive outer shield surrounding the insulating sheath, a separately molded plastic insulative shield disposed adjacent an opening formed in the conductive outer shield and held by the inner insulating sheath and a conductive voltage detection test point terminal disposed within the plastic insulative shield, wherein the test point terminal is capacitively coupled to the internal conductor for external testing of a voltage of the connector. In a preferred method for forming an electrical cable connector, such as a loadbreak power cable elbow connector, having a voltage detection test point, an insulative shield is first molded from a thermoplastic and a conductive voltage detection test point terminal is inserted within the plastic insulative shield. An outer shield is then molded from a conductive material. The conductive outer shield has an opening formed therethrough for accommodating the pre-assembled insulative plastic shield and test point terminal. After the pre-assembled insulative plastic shield and test point terminal are positioned adjacent the opening of the conductive outer shield, and after the conductive outer shield and an internal conductor are positioned within a mold cavity, an inner insulative housing is molded within the conductive outer shield and around the internal conductor. Upon molding, the pre-assembled insulative plastic shield and the test point terminal is held to the inner insulative housing. As a result, the test point terminal becomes capacitively coupled to the internal conductor for external testing of a voltage of the connector.

Pulsating light is used to penetrate a user's finger placed an input surface (which can be a fiber optic surface) of a video camera to avoid the effects of bloodflow from a normal human pulse on the quality of the image which would otherwise change the contrast of the image. The use of pulsating light of shorter durations than a typical human pulse provides an accurate image of a portion of a finger for identification. A retractable cover blocks the fiber optic input surface during a non-working mode, and allows access for identification during a working mode. A light source having a plurality of light emitting diodes provides light that diaphans a portion of the finger. Several successive frames of image signals allow for biometric detection and verification of a human pulse to ensure the finger is not a counterfeit.
