A lamp clamp used to fix a light source on an object is disclosed. The lamp clamp includes a first clamping member and a second clamping member. The first clamping member includes a lamp fixing portion, a connecting portion and a stopping portion. The lamp fixing portion is used to fix the light source.

The connecting portion is connected to the lamp fixing portion. The stopping portion is movably connected to the connecting portion and has a stopping surface selectively disposed at one of plural positions on the connecting portion. The second clamping member is connected to the connecting portion to clamp the object between the stopping surface and the second clamping member.

A task light that includes a plurality of light emitting diodes (LED's) adapted for providing a variable intensity of emitted light; a light directing member for directing light from the LED's onto a work surface; a control logic, electrically connected to a light intensity selector, an ambient light sensor, and the plurality of LED's and wherein the control logic compares the intensity of ambient light in the area surrounding the work surface with the desired intensity of light to be provided at the work surface and adjusts the supply of electrical power to the LED's so that the total of the variable intensity of emitted light and the intensity of ambient light in the area surrounding the work surface is approximately equal to the desired intensity of light to be provided at the work surface.

A linear multi-color LED illumination device that produces uniform color throughout the output light beam without the use of excessively large optics or optical losses is disclosed herein. Embodiments for improving color mixing in the linear illumination device include, but are not limited to, a shallow dome encapsulating a plurality of emission LEDs within an emitter module, a unique arrangement of a plurality of such emitter modules in a linear light form factor, and special reflectors designed to improve color mixing between the plurality of emitter modules. In addition to improved color mixing, the illumination device includes a light detector and optical feedback for maintaining precise and uniform color over time and/or with changes in temperature. The light detector is encapsulated within the shallow dome along with the emission LEDs and is positioned to capture the greatest amount of light reflected by the dome from the LED having the shortest emission wavelength.

A tube lamp has a tubular portion that serves both as a light guide for energy from a solid state source and as a container for a material bearing a nanophosphor that is pumped by the energy from the source as the energy traverses the light guide. However, the tubular portion of the light guide also allows emission of light produced by the phosphor when excited. The material with the nanophosphor dispersed therein may appear either clear or translucent when the lamp is off and the nanophosphor is not excited by energy from the source.

An illumination device for an optical device, a microscope or a macroscope includes a first illumination source configured to emit light which is directed via an illumination beam path onto an object to be illuminated that is arranged in an object plane. At least one second illumination source is positionable in the illumination beam path, and is transparent or semitransparent as well as self-luminous. The at least one second illumination source is configured to allow light emitted from the first illumination source to pass through at least in part. The object plane having the object to be illuminated is configured to be illuminated both by the first and by the at least one second illumination source.

A winch comprises a cable roll; a cable having one end fixed to the cable roll and another end configured to electrically connect an electric device to the cable, wherein the cable is further configured to provide the electric device with electric power and/or with data; a framework to which the cable roll is mounted; measuring means connected to the framework and configured to provide data related to the length of an unwound part of the cable; and processing means configured to control winding and unwinding of the cable based on data provided by the measuring means. The cable has a predetermined reference state at which a predetermined fixed reference point is at a reference position in relation to a coordinate system, wherein the length of unwound cable is defined as the distance measured along the cable, between the location of the predetermined fixed reference point and the reference position.

Cable management systems that include a light source, such as a low voltage light source, integrally formed into or mounted to a cable management frame.

A uniform luminance light-emitting diode (LED) circuit board includes a first primary trace and a second primary trace mounted on a substrate along a direction and are spaced apart, multiple LED strings mounted on the substrate along the direction and parallelly connected between the first primary trace and the second primary trace, a first power trace and a second power trace respectively connected to the first primary trace and the second primary trace, and a first auxiliary trace with two ends respectively connected to the second primary trace and the second power trace. By adjusting trace widths of the first primary trace and the second primary trace to limit current passing through each LED string and using the first auxiliary trace to provide an additional current path, identical current flowing through all the LED strings results in uniform luminance of the LED strings.

An improved and modular lighting fixture that reduces shipping and storage requirements and costs, facilitates simple assembly and repair, and that is modularly configurable to provide flexibility when designing and installing lighting fixtures. The improved lighting fixture also reduces the adverse effect of external environmental factors such as moisture, dust, etc. by providing a seal that impedes ingress into the modular lighting fixture.

A HubblePerkinElmer correcting mirror for luminaries intended to illuminate a room, where the luminaries may send direct bright light towards directions that are inconvenient. Similarly to its space telescope device, the HubblePerkinElmer correcting mirror redirects the emitted light to other directions that are more advantageous for illumination, particularly to avoid direct bright light onto the eyes of humans in the space.
