Abstract: To reduce or prevent adhesive particles from being scattered toward a light-emitting portion of an arc tube and an auxiliary reflecting surface of an auxiliary mirror even when an inorganic adhesive injected for fixing the auxiliary mirror to the arc tube is boiled, a method of manufacturing a light source lamp includes: setting a light-reflecting surface of the auxiliary mirror so as to face the light-emitting portion of the arc tube and injecting an adhesive into a gap between the auxiliary mirror and the arc tube; heating and curing the adhesive from a side nearer to the light-emitting portion of the arc tube; and attaching the reflector to the arc tube with the auxiliary mirror fixed thereto. For example, a heated air blowoff and light irradiation toward the adhesive form the side nearer to the light-emitting portion of the arc tube may be performed. Further, a projector includes: an illumination system with the light source lamp; an optical modulator; and a projector lens.

Abstract: A headlamp unit for a vehicle has two LEDs, two sub-reflectors, a main reflector and a convex lens. The sub-reflector reflects light emitted by the LED and has a reflective surface and an opening. The reflective surface is a part of an ellipsoid of revolution having a first focus position located to the LED and a second focus position located on an upper side of an optical axis. The opening is formed on an upper portion of the sub-reflector so as to substantially coincide with a horizontal plane including the optical axis. The main reflector is disposed so as to be opposed to the sub-reflectors and reflects light reflected by the sub-reflectors. The convex lens forward outputs light reflected by the main reflector to present a desired light distribution pattern.

Abstract: A backlight illumination system for illuminating a large area with light of a uniform color has a set of a pre-determined number of light emitters arranged along a straight line. The set is divided in a plurality of subsets, each subset including at least two light emitters. Each subset comprises light emitters with substantially the same light-emission color point, the respective subsets having color points different from each other. As a first step, the light emitters of the subset with a smallest number of light emitters are assigned to respective substantially equidistant positions. The light emitters of the set are assigned to the respective positions by iteratively starting with the subset with the smallest number of light emitters, assigning the light emitters of the subset to substantially equidistant positions which are not yet occupied. The backlight illumination system according to the invention has a uniform light and color distribution.

Abstract: Each light path changing member forms a first light flux by reflecting a half of light flux emitted from a particular area (central area or peripheral area) of light source in one direction using a polarizing beam splitter, and forms a second light flux by reflecting the other half of light flux, which has passed through the beam splitter, in the afore-mentioned direction using the first mirror. Then, each light path changing member transmits a half of a light flux emitted from the other light source and guided by the second mirror in the same direction as that in which the first light flux has been guided using the polarizing beam splitter, and superposes the light flux on the aforementioned first light flux, and reflects the other half of light flux, which has been reflected by the beam splitter, in the aforementioned direction using the first mirror, and superposes the light flux on the second light flux.

The apparatus comprises a light source, a reflector, and two substantially parallel sets of partially overlapped light deflectors wherein a gap exists between either two adjacent light deflectors of the same set or one light deflector and the reflector. A portion of emitted light is directed to the light guide after being reflected from the reflector. The remaining portion of light is directed to the light guide either after it has been deflected by the light deflectors or deflected by the light deflectors prior to being reflected by the reflector. Parallel light received at the light guide is deflected to the plane display as a backlight source of the plane display after passing the diffusers.
