An LED pump light with multiple phosphors is described. LEDs emitting radiation at violet and/or ultraviolet wavelengths are used to pump phosphor materials that emit other colors. The LEDs operating in different wavelength ranges are arranged to reduce light re-absorption and improve light output efficiency.

A light emitting apparatus includes a light source, a thin plate-shaped mirror unit which guides light from the light source, and a tension imparting means which imparts tension to the mirror unit. The tension imparting means may have at least any one of a first tension imparting mechanism which imparts tension in a first direction toward the light source along a surface of the mirror unit and a second tension imparting mechanism which imparts tension in a second direction opposite to the first direction, and further, the tension imparting mechanism may have at least any one of a third tension imparting mechanism which imparts tension in a third direction in parallel with the light source along the surface of the mirror unit and a fourth tension imparting mechanism which imparts tension in a fourth direction opposite to the third direction.

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.

This invention relates to a new way to signal or display light by way of a portable light device that includes a reflector structure with a flexible and floppy end. The flexible and floppy end contains reflectors or reflective pieces or reflective fabric such that the light is reflected in many directions when the devices is waved around by a user.
