Projector device

A projector device comprising:

• a casing (1) having disposed therein a lamp unit (4) comprising a lamp (41) and a reflector (46), a cooling unit comprising a cooling fan (42) for cooling the lamp unit (4), and an optical system for generating color image light with the lamp unit (4) serving as a light source, the reflector (46) having a reflecting portion (46a) having a reflecting surface for reflecting light emitted from the lamp (41) toward the optical system, and a plurality of side walls (46b-46e) extending from the reflecting portion (46a) toward the optical system to surround the lamp (41), a first side wall (46b) of the plurality of side walls (46b-46e) being provided with an air intake portion for introducing air delivered from the cooling unit toward the lamp (41), with a second side wall (46c) opposed to the first side wall (46b) being provided with an air discharge opening (55) opposed to the air intake portion, the air intake portion of the reflector (46) being provided with a first air intake opening (53) and a second air intake opening (54) at both sides of a plane including a central axis of the lamp (41) and orthogonal to the first side wall (46b), with a wind blocking wall (56) being defined between both air intake openings (53, 54), wherein the first air intake opening (53), the second air intake opening (54) and the air discharge opening (55) are each constituted of a plurality of small holes (57, 58), and each of the small holes (57) constituting the first intake opening (53) and the second intake opening (54) has an opening area larger than that of each of the small holes (58) constituting the air discharge opening (55).
