Description
Technical field
A kind of laser excitation equipment is the utility model is related to, a kind of particularly laser reflection excitation laser white light source is set
It is standby, apply in lighting area.
Background technology
Existing laser excitation is usually to be irradiated to change light in the side back to light conversion medium beam projecting face
Medium is excited, and the outgoing light source of the required colour temperature of acquisition is emitted by the front (i.e. beam projecting face) of light conversion medium.But
Since the more general light beam of the light intensity of laser is much better than, and hot spot compares concentration, and face often occurs in the edge for being easy to cause outgoing light source
Phenomena such as color is uneven, brightness is bad, have impact on the source mass of outgoing light source.Therefore one kind is provided using front excitation front to go out
Light, outgoing light source uniformly and the good laser excitation equipment of good brightness, quality oneself become when business urgently.
Utility model content
In order to overcome existing laser by exciting light conversion medium using the emergent light caused by the light extraction of back side illuminaton front
The shortcomings that source mass in source is bad, brightness is bad, the utility model provide a kind of laser excitation equipment, it uses front illuminated
