摘要： A lighting device comprising a light source being configured to generate source light of a white light emission spectrum having a color correlated temperature (CCT) in a range of 2500-20000K and comprising a control unit being configured to control a lighting element for tuning of the source light with respect to a ratio between a first emission peak in a wavelength range of 460-490 nm and a second emission peak in a wavelength range of 430-460 nm. Thus a lighting device with a tunable/adjustable spectrum is provided that can switch between a first operation state of energy efficiency lighting with a blue peak in the second wavelength range of 430-460 nm, but with blue hazard risk, and a second operation state of less efficient but safe, healthy lighting with a biological stimulant having a blue peak in the first wavelength range of 460-490 nm.

摘要： A tripod light includes a frame supporting a light assembly, and a support assembly coupled to the frame and configured to support the frame on a surface. The support assembly includes a first leg, a second leg, and a third leg. The support assembly is pivotable relative to the frame about a first axis between a stowed position in which the support assembly including the first leg, the second leg and the third leg is adjacent the frame, and a deployed position in which the support assembly including the first leg, the second leg, and the third leg extends away from the frame. Each of the second leg and the third leg is configured to rotate relative to the first leg about a second axis between a collapsed position and a respective extended position of the second leg and the third leg.

摘要： A light source module includes a blue light generation portion, a cyan light generation portion, a yellow-green light generation portion and a red light generation portion. The red light generation portion includes a first additional light emitter and a second additional light emitter, the first additional light emitter emits a light having a main emission peak in the red light wave band, the second additional light emitter emits a light having a secondary emission peak in the red light wave band, and a spectral intensity of the secondary emission peak is 30.0%˜80.0% of a spectral intensity of the main emission peak. An emitted light of the light source module is a white light with a color temperature of 3000K˜6000K, and in a CIE1931 color space, a distance between the emitted light and a blackbody locus BBL is duv=−0.007˜0.007.

摘要： This disclosure relates to a surgical lighting device comprising a shell (12), a plurality of light sources (24) coupled to the shell, and a closure plate (18) for closing the lighting device by allowing light to pass through. The closure plate comprises a plurality of lens elements, each lens element being configured to collect and focus light from a corresponding light source to generate a light spot of a predetermined diameter located at a predetermined distance from the lighting device. In order to simplify the structure of the lighting device, the light sources and the cover plate are arranged in such a way that the light beams coming from the light sources and received by the associated lens elements arrive at the lens elements without substantial reflection or deflection. The closure plate therefore comprises all the optics necessary for collecting and focusing the light from the light sources.

摘要： Alignment systems and devices are provided for controlling the alignment of an optical payload. In some embodiments, an optical positioning system is provided that includes a yoke supporting an optical payload. The yoke, which includes a plurality of articulated segments and associated pivot joints, is mechanically coupled to the optical payload, such that when the optical payload is oriented in a given direction, such as towards a distal target, the optical payload is rotatable about a distal pivot axis associated with a distal pivot joint of the yoke. The pivot joints of the yoke may be configured such that the rotation axis associated with a given pivot joint passes sufficiently close to a respective center of mass of a distalward portion of the optical alignment system beyond the given pivot joint, such that the position and orientation of the optical payload is maintained in the absence of external forces.

摘要： A desktop illumination device includes a light source; and a light guide including a light guide plate. The light guide plate has a light incident surface and first and second main surfaces. An angle at which an intensity becomes maximum in a light distribution of light emitted from the first main surface is in a range of −90° or more to less than 0°, in a case where an axis passing through a center of the first main surface and perpendicular to an installation surface is defined as a vertical axis, and in a plane including the vertical axis and perpendicular to the installation surface, a direction parallel to the installation surface is defined as vertical 0°, an upward angle with respect to the vertical 0° is defined as a positive angle, and a downward angle with respect to the vertical 0° is defined as a negative angle.
