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).

摘要： A projection type video display apparatus is provided with an LED array for emitting light in red, an LED array for emitting light in green, and an LED array for emitting light in blue. On a light-incident side of a rod integrator, time-dividing mirrors 2A, 2B arranged in a cross manner, for guiding the light from each LED array to an inside of the rod integrator, are arranged. Furthermore, on a light-emission side of the LED array for emitting the light in red, a time-diving mirror is arranged, and on a light-emission side of the LED array for emitting the light in blue, a time-dividing mirror is provided. Each time-dividing mirror switch either to reflect the light or to transmit the light, depending on whether or not voltage is applied thereto. At time-dividing lighting timing of the LED arrays, the time-dividing mirrors switch either to reflect the light or to transmit the light. In addition, video signals of videos of respective colors are supplied to a liquid crystal display panel in a time-dividing manner.

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 illumination apparatus includes; a first solid-state light source, a second solid-state light source, a first arrangement member provided with a first arrangement surface, a second arrangement member provided with a second arrangement surface, an optical unit configured to reduce a dispersion angle of a light beam. The first solid-state light source emits a light beam having a first directivity. The second solid-state light source emits a light beam having a second directivity greater than the first directivity. A distance from the second arrangement surface to the second light-entering surface is longer than a distance from the first arrangement surface to the first light-entering surface.
