    摘要： The invention provides a reflector lamp comprising a light source, a lens and/or a reflector arranged coaxially with the light source in a spaced-apart fashion, and a push-push adjustment assembly for varying a beam angle of the light beam in a push manner. The push-push adjustment assembly comprises a frame coupled fixedly to the lamp, an actuator in operative connection with the lens or the reflector, wherein the actuator movably rests in the frame so that the movement of the actuator enables the lens or the reflector to slide relative to the light source thereby to provide variable axial spacing between the lens or the reflector and the light source, and a push-push latch mechanism coupled to the actuator and/or the frame to move the actuator in the frame. The adjustment assembly of the invention allows to vary the light beam angle by directly or indirectly applying a pushing force onto the lens and/or the reflector in front of the reflector lamp.

    摘要： A lighting apparatus (10) for a building structure (12). The apparatus includes a plurality of LEDs (14) and a holder (16) having a heat sink (18) for holding the LEDs (14) along a length of the holder (16) and dissipating heat from the LEDs (14). The apparatus includes a first bracket (22) which extends outward from the holder (16) in a first direction on a first side of the holder (16) and is moveably attached to the holder (16) . The apparatus includes a second bracket (28) which extends outward from the holder (16) in a second direction on a second side of the holder (16) and is moveably attached to the holder (16). The apparatus includes a first screen (34) attached to the first bracket (22) on the first side of the holder (16) and a second screen (36) attached to the second bracket (28) on the second side of the holder (16) . When the first bracket (22) is moved, the first screen (34) is moved relative to the holder (16) on the first side of the holder ; and when the second bracket (28) is moved, the second screen (36) is moved relative to the holder (16) on the second side of the holder. A method for lighting a building structure with a lighting apparatus is also disclosed.

    摘要： To provide a compact pivot capable of efficiently transferring a load acting on the pivot to a case that bears the pivot, a pivot (1) includes a sphere unit (10) formed such that a through hole (11) capable of holding a shaft member (131) passes through a center of the sphere unit, and a sliding guide unit (20) to be suspended or mounted, wherein the sphere unit (10) is coupled to the sliding guide unit (20) via two legs (30). Further, a bearing mechanism (3) includes the pivot (1), and a case (2) that bears the pivot (1), the case (2) is formed of two half-split structures (40, 50) having receiving surfaces (41, 51) for bearing the sphere unit (10), and the two half-split structures (40, 50) are locked together by at least three locking means (42, 52).

    摘要： A light emission device (1) includes a light source (3) that emits an excitation light beam (101), a light deflector (140) that deflects the excitation light beam (101), a wavelength converter (160) that receives and converts the excitation light beam (101) deflected by the light deflector (140) to wavelength-converted light of a different wavelength and emits the wavelength-converted light, and a light concentration section (10) that focuses the excitation light beam (101) on the wavelength converter (160). The light concentration section (10) includes a first optical system (11) disposed between the light source (3) and the light deflector (140), and a second optical system (12) disposed between the light deflector (140) and the wavelength converter (160). In the second optical system (12), a focal length of an Ay-axis is shorter than a focal length of an Ax-axis, where the Ax-axis is defined as an axis that has a lowest beam parameter product of the excitation light beam (101), and the Ay-axis is defined as an axis orthogonal to the Ax-axis in a cross section perpendicular to a propagation direction of the excitation light beam (101).
