A portable light may comprise: a light body defining at least a part of a passage, a light source supported by the light body, a switch for controlling the light source, and a deployable hanger for hanging the light from an object. The deployable hanger may comprise: a spring finger proximate the passage, and a hanger ring having at least first and second flat surfaces disposed in the passage and engaging the spring finger. The spring finger bears against the first flat surface of the hanger ring for biasing the hanger ring to a first position and bears against the second flat surface of the hanger ring for biasing the hanger ring to a second position.

LED-integrated lens comprising a light-entering section (1) in the shape of a hole, a light-emitting section (2) in the shape of a cup, incorporating an optical lens (3) positioned between said light-entering and light-emitting sections (1, 2) wherein the external surfaces of the light-entering (1) and of the light-emitting (2) sections include portions having densely-distributed convex facets. This lens enhances light utilisation efficiency, avoids creating spots with colour aberration hence greatly improves colour rendering.
摘要:
An LED lamp conversion module for converting an outpost lighting fixture from incandescent or halogen lighting to LED lighting, the conversion module including a base and an LED lamp attached to the base, where the LED lamp has at least one LED. Electronics are adapted to illuminate the at least one LED of the LED lamp when powered with a current. The conversion module also includes an electronic connection member in electrical communication with the electronics. The conversion module may be used to replace an incandescent or halogen lamp in an outpost lighting fixture by connecting the base to the outpost lighting fixture and connecting the electronic connection member to a power source of the outpost lighting fixture.

In an embodiment, a polycarbonate composition comprises: polycarbonate; 7 wt % to 20 wt % titanium dioxide, based upon a total weight of the polycarbonate composition; an optional flame retardant; and an optional UV stabilizer. A plaque formed from the polycarbonate composition has a reflectance of greater than or equal to 95%, as determined by reflectance measurements using a Gretag Macbeth Coloreye spectrophotometer (D65 light source, 10 degree observer, UV included) made at a wavelength of 680 nm. In an embodiment, a polycarbonate composition comprises: a polycarbonate; 7 to 20 wt % titanium dioxide; a flame retardant; and an optional UV stabilizer; wherein the polycarbonate composition has a maximum reflectance of greater than or equal to 95%. The melt volume rate as determined at 300° C. using a 1.2 kilogram weight, in accordance with ASTM D1238-04 is from 5 to 30 grams per 10 minutes.
