Cylindrical white light laser diode packaging structure

An improved cylindrical white light laser diode packaging structure, comprising:

• a base with a concave groove in the middle for fixing a ceramic fluorescent powder, the base is also provided with a seat bar protruding adjacent to the concave groove, the front of the seat bar is in an oblique plane for fixing a blue-light laser chip, and the base is equipped with several feet on the bottom surface, and a cover body with a light transmissive mouth on the top surface is fixed with the base to form a cylindrical white light laser diode;
• and
• the upper opening of the concave groove is larger than the bottom of the concave groove, and the concave groove can improve the reflection and concentration;
• Wherein the blue laser beam is projected by the blue laser chip in the oblique plane of the seat bar, and the blue laser chip projects the blue laser beam downwardly at an oblique angle toward the ceramic florescent powder, with which the florescent powder thereof generates a physical excitation property to reflect a white laser beam, then a white light laser is emitted by the light transmissive mouth of the cover body.
