Abstract
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.
Claims17
A light source unit, comprising:
- a substrate;
- a phosphor layer on the substrate;
- a light source configured to irradiate the phosphor layer with exciting light;
- and
- a support section configured to support a first portion of the substrate, wherein
- the support section is in contact with both the first portion of the substrate and a part of a second portion of the substrate,
- the second portion of the substrate faces the phosphor layer, and
- the first portion of the substrate is different from the second portion of the substrate.

A projection-type display, comprising:
- a substrate;
- a phosphor layer on the substrate;
- a light source configured to irradiate the phosphor layer with exciting light;
- a support section configured to support a first portion of the substrate, wherein
- the support section is in contact with both the first portion of the substrate and a part of a second portion of the substrate,
