An illuminated indicator for a doorbell can be arranged to receive light along an optical axis (e.g., that is perpendicular to a front face of the doorbell housing) and emit the light from an output portion that defines a closed loop (e.g., that extends around the optical axis) and in a direction that is parallel to the optical axis. The illuminated indicator can include a light pipe that receives light along the optical axis and reflects the light to follow a radially outward and divergent path, e.g., that is perpendicular to the optical axis. The radially outward and divergent light can be reflected to follow a path that is parallel to the optical axis for emission at an output portion of the light pipe. The light pipe can be configured to transmit a doorbell switch activation force to other parts of the doorbell to cause actuation of the switch.

A light-emitting device includes a light-emitting section, a lens, and a movement control section, the movement control section changing an illumination position and a spot size of a laser beam in the light-emitting section by changing a relative position of the lens with respect to the light-emitting section.

A system for forming poured surfaces having a desired point of light patterns emitting from the top surface thereof is provided. The system retains the optic fibers along the desired point of light pattern through the pouring of the poured surface. The system incorporates a guide post and coupled positioning apparatus adapted to support each optic fiber prior to and during the pouring and setting of the poured surface so that the optic fibers protrude above the top surface after setting, to be cut flush, forming the desired pattern of points of light.

A light-emitting diode light string with an optical fiber includes a first wire, a second wire, a light-emitting diode, and an optical fiber. The light-emitting diode is connected in parallel between the first wire and the second wire, which has a light-emitting surface, and when activated, generates a light at the light-emitting surface to have a first brightness. The optical fiber has a light entering end, a side light exiting portion, and a light exiting end. The light entering end is connected to the light-emitting surface, and the light entering end, the light exiting end, and the light-emitting surface are substantially aligned with a plumb line. The light has a second brightness at the light exiting end, the light has a third brightness at the side light exiting portion, the first brightness is substantially equal to the second brightness, and the second brightness is greater than the third brightness.

A variable lighting apparatus allows the light to selectively enter the plurality of optical fibers by changing the position of the light output member having a circular plate shape in the state in which the number of light sources is minimized, such that the optical fibers simultaneously or individually emit light, and thus the patterns in which the light is to be outputted are diversified. In addition, the variable lighting apparatus may minimize the number of required light sources and implement various lighting images only by using the light output member, thereby reducing the manufacturing costs and simplifying the structure.

A novel lighting device is provided which projects two simultaneous yet distinct lighting effects to its surrounding areas from a central mounted and covered light source, firstly illuminating a proximate surface directly by the light source and by reflection of a cover, and secondly light is remotely provided by optically conductive materials which transmit and project light, such that the central light source projects onto proximate surface areas directly and by reflection, and light projects remotely and outwardly, carried from said source by light transmission utilizing optically conductive materials.

An illumination unit for illuminating an area of operation during open surgery. The illumination unit including: a body; a fiber bundle configured to guide light towards a distal end of the body, and a reflector body arranged at the distal end of the body. Where at least a part of the fiber bundle is guided inside the body along a longitudinal direction, the fiber bundle is split up into a plurality of optical fibers which form a fiber layer on an inner surface of the body, end faces of the plurality of optical fibers are arranged at the distal end of the body, the reflector body encloses the end faces of the plurality of optical fibers in a radial direction and extends distally beyond the distal end of the body in the longitudinal direction, and an inner surface of the reflector body is a reflective surface.
