1. A light source apparatus, comprising: a light source; and a conductor to conduct heat diffused from the light source to a spreader to spread heat, the conductor having a plurality of parts.
2. The light source apparatus according to claim 1, wherein: the conductor includes a first part to conduct heat diffused from a back surface of the light source when a light emitted side of the light source is defined as a front surface; and a second part to conduct heat diffused from a lateral surface of the light source.
3. The light source apparatus according to claim 2, wherein the second part is sandwiched between the first part and a third part.
4. The light source apparatus according to claim 2, wherein the first part is made of a material different from the second part.
5. The light source apparatus according to claim 1, wherein the conductor includes a first part to directly conduct heat diffused from the light source, and a second part to indirectly conduct heat diffused from the light source, the second part being sandwiched between the first part and a third part.
6. A projector apparatus, comprising: a light source apparatus, having: a light source; and a conductor to conduct heat diffused from the light source to a spreader to spread heat, the conductor having a plurality of parts.
BACKGROUND
[0001] The present technology relates to a light source apparatus and a projector apparatus. More particularly, the present technology relates to a light source apparatus and a projector apparatus capable of effectively dissipating heat generated.
SUMMARY
[0002] Projectors that project images or texts on screens become popular. Many of the projectors use high-intensity discharge lamps as light sources. In recent years, those using light-emitting diodes, laser diodes or the like have been developed.
[0003] In the projectors, high light intensity is necessary for brighten. When the light intensity is increased, heat generated from the light source is also increased. Its countermeasure is necessary. For example, Japanese Patent Application Laid-open No. 2011-76781 suggests that a heat dissipating member is attached to the light source to counter the heat generated.
[0004] Japanese Patent Application Laid-open No. 2011-76781 suggests that a heat sink having heat dissipation fins arranged at light sources is disposed via a heat transfer member to release heat generated from the light sources.
[0005] In such a configuration, when a side where the light sources of the heat transfer member is defined as a front surface, heat is received at the front surface. As a result, flatness at a back surface is not easily provided and accuracy is difficult to be regulated. The heat from the light sources is transferred to other member disposed at the front surface of the light sources such as a lens, whereby properties may be degraded.
[0006] In view of the above-mentioned circumstances, it is desirable to provide a configuration that can dissipate heat emitted from the light source.
[0007] According to an embodiment of the present technology, a light source apparatus includes a light source, and a conductor to conduct heat diffused from the light source to a spreader to spread heat, the conductor having a plurality of parts.
[0008] The conductor may include a first part to conduct heat diffused from a back surface of the light source when a light emitted side of the light source is defined as a front surface, and a second part to conduct heat diffused from a lateral surface of the light source.
[0009] The second part may be sandwiched between the first part and a third part.
[0010] The first part may be made of a material different from the second part.
[0011] The conductor may include a first part to directly conduct heat from the light source to the spreader, and a second part to indirectly conduct heat diffused from the light source to the spreader. The second part may be sandwiched between the first part and a third part.
[0012] A projector apparatus according to an embodiment of the present technology includes a light source, and a conductor to conduct heat diffused from the light source to a spreader to spread heat, the conductor having a plurality of parts.
[0013] In the light source apparatus according to the embodiment of the present technology, the conductor to conduct the heat diffused from the light source to the spreader to spread heat has a plurality of the parts.
[0014] In the projector apparatus according to the embodiment of the present technology, the conductor to conduct the heat diffused from the light source to the spreader to spread heat has a plurality of the parts.
[0015] According to the embodiment of the present technology, there is provided a configuration that can dissipate heat emitted from the light source.
[0016] These and other objects, features and advantages of the present technology will become more apparent in light of the following detailed description of best mode embodiments thereof, as illustrated in the accompanying drawings.
