摘要： An optical element includes a dichroic surface formed by a multilayer dielectric film or the like and a polarized beam splitter surface formed by a multilayer dielectric film or the like. The dichroic surface transmits light (G and R) from a green wavelength band to a red wavelength band irrespective of the polarization directions of light, and reflects light (B) in a blue wavelength band. The polarized beam splitter surface reflects an S-polarized light (Gs) in a green wavelength band. Furthermore, the polarized beam splitter surface transmits an S-polarized light (Bs) and a P-polarized light (Bp) in the blue wavelength band, and also transmits the S-polarized light (Rs) and P-polarized light (Rp) in the red wavelength band.

摘要： An illumination apparatus includes a red light valve, a green light valve, a blue light valve, a polarization adjustment element, and a color combiner. The polarization adjustment element adjusts polarization of fourth color component light. The color combiner combines light emitted from the red light valve, the green light valve and the blue light valve. Superimposed component light which is any one of a red component light, a green component light and a blue component light enters the polarization adjustment element together with a fourth color component light. The polarization adjustment element transmits the superimposed component light without adjusting the polarization, and transmits the fourth color component light with adjusting the polarization. The superimposed component light and the fourth color component light emitted from the polarization adjustment element enter a specific light valve corresponding to the superimposed component light, among the red light valve, the green light valve and the blue light valve.

摘要： An illuminating device comprises a first light source in which LED chips are arranged in an array shape and a second light source in which LED chips are arranged in an array shape. The two light sources of each illuminating device are arranged such that the main light-emission optical axes of the light sources are perpendicular to each other. Moreover, a time-division switching mirror is provided at a crossing position between the main light-emission optical axes. The first light source and the second light source alternately emit pulses of light. The pulsed emission is a method of supplying a large amount of electric currents to the LED chips in a short time period, and a light-emitting amount increases compared to a steady-state emission of the LED chips. The time-division switching mirror becomes a transmitting state when the first light source is lighted, and becomes a reflecting state when the second light source is lighted.

摘要： An LED light source is formed of an LED and an angle control lens. The angle control lens includes a transparent member in a shape of a rotational symmetry, and includes a center convex curved surface area (light-emission area) A1, a peripheral curved surface area (light-emission area) B1, a peripheral curved surface reflection area C1, a center concave curved surface area (light-incidence area) D, and a convex curved surface area E formed between the areas A1, B1. The convex curved surface area E is formed in a position for receiving direct incoming light from the LED (direct incoming light deviated from the center portion), and is optically constructed to anteriorly emit this received light (in a direction intended to be emitted as a result of a light-emission angle being controlled).
