An optical device including a support mounted on a rotational-drive motor, and a reflective optical component, the support including at least one sleeve coaxial with the rotational-drive axis, of which sleeve one end defines an inlet orifice and which sleeve in its wall includes an opening defining an outlet orifice, and inside which sleeve the reflective optical component is housed in such a way that a beam of light entering via the inlet orifice is reflected by the reflective optical component to exit via the outlet orifice. An optical component mounted and retained in the sleeve as a result of cooperation of shape between it and the wall of said sleeve is also discussed.

A light source module includes a first light-emitting unit, a second light-emitting unit, a first dichroic mirror, and a wavelength conversion unit. The first light-emitting unit emits a first color light. The second light-emitting unit emits a second color light. The first dichroic mirror allows the first color light to transmit through and has a passing area. The passing area allows the second color light to pass through. The wavelength conversion unit includes a substrate and a phosphor layer disposed on the substrate. The phosphor layer converts the first color light transmitting through the first dichroic mirror into a third color light, and reflects and scatters the second color light passing through the passing area. The first dichroic mirror reflects the second color light reflected by the wavelength conversion unit and the third color light.

A solar module assembly includes a frame having an upper portion encompassing an area and a mid portion disposed below the upper portion. A plurality of solar panels is arranged in a string, sandwiched between two transparent panes forming a single string panel. The solar panels occupy less than the area of the upper portion. Each of the plurality of solar panels has a pair of opposing edges. A reflector is mounted on the mid portion to reflect light selectively.

A high-efficiency linear light source focused strip lamp has a strip lamp frame, a strip lamp plate provided on the strip lamp frame, a condensing lens arranged above the light emitting direction of the light-emitting chip, and a strip lamp cover connected to the strip lamp frame and located above the condensing lens; the strip lamp cover is provided with a convex lens array that visually stretches the light-emitting chip along a length direction. The high-efficiency linear light source focused strip lamp performs light distribution through the concentrating lens in the vertical length direction, and achieves high-efficiency sweeping function, and in the longitudinal direction, the light-emitting chip is performed visually stretching by the convex lens arrays on the strip lamp cover, thus achieving the effect of the line light source, solves the original glare problem without affecting the efficiency.

A light control apparatus includes a diffuser plate, a light source, a light pipe, and a light blocker. The diffuser plate includes at least one opening therein. The diffuser plate includes feature located around the opening in the diffuser plate that exposes a portion of the diffuser plate. A light source positioned proximate a second surface of the diffuser plate is optically coupled to a light pipe positioned around a portion of the opening near the second surface of diffuser plate. A light blocker is positioned near a second portion of the at least one feature. The light blocker is positioned between the light source and the second portion of the feature, the light blocker having an opening therein to allow light to pass from the light source to the diffuser plate proximate the second portion of the feature.
