1Temperature

If separate cooling means are provided for light emitting elements and fluorescent element, then each element can be cooled effectively, but device complexity and size increase

Engineering Contradiction:

Improvecooling effectivenessVSAvoidcooling system complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The patent combines separate cooling means for light emitting elements and fluorescent element into a single common cooling member. The cooling member includes a first cooling surface coupled to light emitting elements and a second cooling surface coupled to the fluorescent element, allowing both elements to be cooled by the same thermal management system rather than requiring independent cooling mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The common cooling member serves multiple functions simultaneously: it cools the light emitting elements through its first cooling surface and cools the fluorescent element through its second cooling surface. This multi-functional design eliminates the need for separate cooling systems while maintaining effective thermal management for both component types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A light source device includes a light emitting element adapted to emit exciting light; a fluorescent element having a phosphor and adapted to convert at least a portion of the exciting light emitted from the light emitting element into fluorescence and to reflect the fluorescence; and a common cooling member adapted to cool the light emitting element and the fluorescent element. The cooling member includes a first cooling surface coupled to the light emitting element for cooling the light emitting element, and a second cooling surface coupled to the fluorescent element for cooling the fluorescent element. The first cooling surface and the second cooling surface are placed in parallel with each other and are placed in such a way as to be oriented in the same direction.
