摘要： A light source device includes: a light source lamp that has a light-emitting portion and sealing sections provided on both sides of the light-emitting portion; a reflector that aligns and irradiates a light beam radiated by the light source lamp in a predetermined direction; and a sub-reflection mirror of which reflection surface opposes to a reflection surface of the reflector and reflects the light beam radiated by the light-emitting portion of the light source lamp toward the reflector. In the sub-reflection mirror, an adhesion surface of an insertion hole is bonded to the sealing section by an adhesive in a condition that the sealing section is inserted in the insertion hole. A cutting portion of the sub-reflection mirror is so formed to extend over a portion bonded by the adhesive in plan view.

摘要： 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.

摘要： A light source lamp unit (10) includes a light source lamp (11), an ellipsoidal reflector (12) and a plate body (19). The plate body (19) is provided behind the reflector (12) with a gap kept therebetween, which has a shape corresponding to the profile of a reflecting portion (122) of the reflector (12). A cooling channel for passing a cooling air is formed between the plate body (19) and the reflector (12). The width of the cooling channel in a direction along an optical axis of the light source lamp (11) is minimized at a part near a neck portion (121) of the reflecting portion (122) and enlarged toward the peripheral edge of the reflecting portion (122) of the reflector (12).
