A light source apparatus according to an embodiment of the present disclosure includes: a rotator including a light emission unit on one surface, a heat dissipation member that is coupled to the rotator, and has a first cylindrical surface substantially parallel to a rotation axis of the rotator, and a housing that contains the rotator and the heat dissipation member, and has a second cylindrical surface substantially parallel to the first cylindrical surface of the heat dissipation member.

Light source apparatus and projection display apparatus

A light conversion device according to one embodiment of the disclosure includes a light conversion section that is rotatable about an axis of rotation, a cooling section that cools the light conversion section, a housing that houses the light conversion section and the cooling section, and a partition member that is provided on the light conversion section, and partitions a space in the housing.

Light conversion device, light source apparatus, and projection display apparatus with improved cooling efficiency

A projection display apparatus according to an embodiment of the present disclosure includes: a light source optical system including a light source section, a light conversion section that converts light emitted from the light source section to light having a wavelength band different from a wavelength band of the emitted light, and a cooling section that cools the light conversion section; and an external casing that houses the light source optical system and has an air inlet and an air outlet that form an airflow path in a linear shape. The light source section and the light conversion section are disposed on the airflow path, and the cooling section is disposed at a position shifted from the airflow path.

Projection display apparatus

A light source unit includes a substrate that is rotatable, a phosphor layer disposed at a center of the substrate, a light source that irradiates the phosphor layer with exciting light, and a support section that supports a portion, of the substrate, except for the center of the substrate. This makes it difficult for heat generated in the phosphor layer to travel to a motor through the substrate.

Light source unit and projection-type display

An object of the present invention is to improve the efficiency of heat dissipation from a phosphor wheel while suppressing the air resistance and noise of the phosphor wheel during the driving of a light source apparatus. A phosphor wheel according to the present invention includes a disc-like substrate, a phosphor layer formed on the substrate, and a plurality of heat dissipation fins overlapping with each other when viewed in a direction orthogonal to a surface of the substrate.
