The present invention discloses a focus-adjustable lamp, provided with an illuminating mechanism on the top end thereof, wherein the illuminating mechanism comprises a light-emitting element, a shield body shielding the outer side of the light-emitting element, a heat dissipating member closely matched with the light-emitting element, and a cover body located on the top end of the illuminating mechanism, the illuminating mechanism is further provided with a light-converging cylinder rotationally sleeving the outer side of the shield body, and the light-converging cylinder is capable of rotating back and forth along a circumferential direction of the shield body to adjust the size of a light spot projected by the light-emitting element on the ground.

An adjustable under cabinet LED light fixture having a tube holding LEDs that can be rotated to different amounts to direct illumination in a particular direction. The LED light fixture can be moved relative to a mounted plate attached to the bottom of a cabinet or the ceiling of a compartment below a sink or the like in a horizontal direction, and held to the mounted plate by magnetic attraction. The LED light fixture can also be dimmable to vary the color temperature of the LED illumination.

A color temperature compensation system comprises a light source, a dimming element for dimming the light source, a color temperature compensation sheet for performing color temperature compensation on light output from the dimming element, in which there are different changes of color value on the color temperature compensation sheet, and a driving mechanism for controlling the movement of the color temperature compensation sheet and driving the color temperature compensation sheet to switch in and switch out of a light path.

Presented is a multiparameter automated luminaire comprised of a plurality of light engine modules, a plurality of which by design homogenize light emitted by its light sources more fully than at least one of the light engine modules, which is intentionally designed to noticeably not fully homogenize the light emitted by its light sources. In the preferred embodiment, the non homogenizing light engine module also includes light modulators optionally engagable to more fully homogenize the light output from that light engine module.

A window covering for natural illumination of building interiors by redirecting the incident daylight at angles that promote its deeper penetration into the interior space. The window covering comprises an optically transmissive, flexible polymeric sheet having a layered structure with a light diffusing output surface and a number of total internal reflection surfaces incorporated into its material. The total internal reflection surfaces are dimensioned such that the multi-layer sheet diffusely redirect at least a portion of light towards a direction which is generally not coincident with the incidence direction.

A desktop USB device has power-wire(s) or storage-wire arrangement. The device has more than one separated distance away USB-Unit(s) by branch-wire(s) and have wire storage arrangement for at least one of an USB jump-wire, an AC power-wire, USB-charger wire or another charging related wire(s). The USB device and separated USB-Unit(s) to be installed on a desktop or floor at a hand-reachable distance from people, and install or attach anywhere by attachment so that there is no need for people to bend body or knee to get the USB-port(s) to charge i-phone or Tablet(s). The current invention use shortest #14 gauge AC wire for power strips and use long length of #18 gauge to supply DC power to USB ports built-in separated USB-unit(s) the charger. The USB-charger power-wire arrangement has by at least one main-wire and plurality of branch-wire(s) to connect with at least one of separated and distance away USB-Unit(s) incorporated with external USB-wire has at least 2 ends with male USB-plug to connect with each unit has at least one of female receiving USB-port(s) inside USB Unit(s), that can supply a desired output-current in the range of from 1.0 A to 50 A and at USB needed VDC by converting input AC power ranging from 110 VAC to 250 VAC. The USB device or power station may also optional to incorporate with at least one additional device such as at least one of (i) AC outlet, (2) sensor(s), (3) motion sensor, (4) remote controller, (5) time display, (6) LEDs, (7) IC, (8) 2nd LED(s) (9) Detector for charging status and system, (10) power fail device, (11) diffusor equipment, (12) color changing, color selection, function selection for LED(s) light illumination. (13) other lights, (14) a power fail device, (15) a smell device, an (16) audio device, a video device.

A spotlight and a method of controlling the spotlight with an external device are provided. The spotlight includes a first light source including a center spotlight, a second light source including area lights, a power supply, a transceiver configured to communicate wirelessly with the external device, and a processor. The processor is operable to receive a first input from the external device specifying a first amount of power to be provided to the first light source, and receive a second input from the external device specifying a second amount of power to be provided to the second light source. The processor is also operable to control the power supply to provide the first amount of power to the first light source in response to the first input, and control the power supply to provide the second amount of power to the second light source in response to the second input.

A visual task or status indicator comprises a tube having a riser region extending away from a base and an illumination output region distal to the riser region. The tube has the tube wall comprising an optical diffuser material. A waveguide, such as a polycarbonate strand or other optical fiber or a bundle of optical fibers, is enclosed within and extends through the riser region into the illumination output region of the tube. The waveguide is configured to emit light laterally in the illumination output region. A light source is coupled to the waveguide. The light source can have a plurality of output light modes, including various colors or intensities or patterns of colors and intensities. Control circuitry is connected to the light source to select the output light modes in response to a control signal. A plurality of indicators can be controlled from a central control hub.
