摘要:
A galvanically decorated decorative element with contour light is produced from at least two plastic components in a material-fit composite, wherein a first plastic component is galvanigable and forms the decorative element. At least one second plastic component is galvano-inert. Consequently, it is uncoated and passes through the electroplating process unchanged. It represents a transilluminable contour light region.

A laser lens glow baton is a hand held, dual purpose, visual signaling baton. This device can be used as a flashlight that projects a well-defined beam of light via its laser lens and assembly or as a highly visible luminary that radiates an intense flux of light similar to neon tube. The laser lens glow baton is useful as a visual-signaling device because the colors of the main body and the colors of the projected beam emitted from the laser lens assembly are easily changed. The laser lens glow baton may be easily fabricated in different lengths because of its compartmentalization of the components.

Illuminating devices are disclosed having plastic light-transmitting article(s) formed from a thermoplastic composition including a polycarbonate having repeating structural carbonate units according to the formula: in which at least 60 percent of the total number of R1 groups contain aromatic moieties and the balance thereof are aliphatic, alicyclic, or aromatic. The composition also includes an epoxy additive having at least two epoxy groups per molecule and a phenolic diphosphite derived from pentaerythritol. The thermoplastic composition exhibits a dE (2000 hrs.) value of less than 1.5 after 2000 hours of heat aging at 130° C., measured according ISO 11664-4:2008(E)/CIE S 014-4/E:2007 using CIE illuminant D65 and a 2.5 mm thick molded plaque of the thermoplastic composition.

The present disclosure relates to a UV LED lamp, and more particularly, to a UV LED lamp which converts UV LED light from a point light source into surface light using the simplest structure and emits the surface light. The UV LED lamp comprises: a UV LED chip; a PCB board having the UV LED chip mounted thereon; and a cover disposed at a distance from the UV LED chip and configured to convert point UV light, emitted from the UV LED chip, into surface light, the cover having an inner surface facing the UV LED chip and an outer surface opposite the inner surface, wherein the inner surface and outer surface of the cover are roughened, and the amount of total reflection from the roughened inner surface is greater than the amount of total reflection from the roughened outer surface.

An LED lighting apparatus includes an LED-mounting base having LED elements mounted on its surface and a heat-dissipating section fixed on the back side of the LED-mounting base. The heat dissipating section is provided with: a core having a sealed space and heat-dissipating fins provided around the core. Thus, an LED lighting apparatus which has a shape substantially the same as that of a large mercury lighting apparatus, and which can efficiently dissipate heat generated from the LED elements, with only the smallest increase in the weight of the apparatus, can be provided. The electronic-circuit housing section may contain an electric circuit for generating power to be supplied to the LED elements. Furthermore, it is desirable to leave a small space in the electronic-circuit housing section so as to absorb the expansion of the cooling liquid, rather than completely fill the electronic-circuit housing section with the cooling liquid.

Promotional items with enhanced advertising messaging. More specifically, embodiments are directed to a metallic-finished promotional item with a laser-engraved message that is illuminated or backlit by incorporating a light source into the promotional item. The light source acts to illuminate or brighten the laser-engraved message when the light source is powered on. Furthermore, according to embodiments, when the light source is not in use, the laser-engraved message remains appealing, hereinafter referred to “daylight appeal”, due to its enhanced contrast with the surrounding metallic finish.

A spotlight includes a body (1) with a transparent front (2) and has LED's (5) as light-emitting elements. This spotlight body (1) and the transparent front (2) are made of plastic material and the printed circuit (6) including the LED's (5) is arranged in a juxtaposed arrangement on a metal plate (4) being fit to dissipate the heat being produced by the LED's, the metal plate being cooled by the water flowing into the body (1) of the spotlight through lateral openings (8) being provided in the body. The body (1) is concavely shaped and has the dissipator plate (4) securely attached to it at its open front end, the body (1) having at its center an inner pillar having a hollowed-out portion (10) and an outer open end (11) to receive the spotlight's electric connections (13 and 14) that will be fitted to it. The dissipator plate (4) is securely attached to the peripheral open front end of the body (1) and onto its central pillar (9) with the intermediary of respective O-ring seals (15 and 16).
