Laser illumination lighting device with solid medium freeform prism or waveguide

A lighting device comprising:

• a luminaire comprising:
• a laser light source configured to be driven by electrical power to emit laser light rays;
• a phosphor plate;
• and
• a solid medium freeform prism to confine incoming laser light rays emitted from the laser light source inside the solid medium freeform prism until conversion into illumination lighting by the phosphor plate, the solid medium freeform prism including:
• an input surface coupled to the laser light source to shape the incoming laser light rays passing through and entering inside the solid medium freeform prism into shaped laser light rays;
• an output surface;
• a highly reflective internal surface to reflect the shaped laser light rays to propagate inside the solid medium freeform prism until emission through the output surface;
• and
• wherein the output surface emits the shaped laser light rays to the phosphor plate;
• wherein the phosphor plate is coupled to the output surface of the solid medium freeform prism to convert the reflected shaped laser light rays into the illumination lighting to emit from the luminaire;
• and
• a laser light source driver coupled to the laser light source to selectively control the laser light source to emit the laser light rays.

A lighting device comprising:

• a luminaire comprising:
• a laser light source configured to be driven by electrical power to emit laser light rays;
• a phosphor plate;
• a solid medium waveguide to confine incoming laser light rays emitted from the laser light source inside the solid medium waveguide until conversion into illumination lighting by the phosphor plate, the solid medium waveguide including:
• an input surface coupled to the laser light source for incoming laser light rays emitted by the laser light source to enter the solid medium waveguide;
• an output surface;
• and
• a highly reflective internal surface to steer the laser light rays passing through the solid medium waveguide to the phosphor plate, the highly reflective internal surface including an initial highly reflective internal surface portion to initially reflect the laser light rays to propagate inside a remainder the solid medium waveguide;
• wherein the phosphor plate is coupled to the solid medium waveguide to convert the reflected laser light rays into the illumination lighting;
• and
• a laser light source driver coupled to the laser light source to selectively control the laser light source to emit the laser light rays.
