Abstract

The present invention relates to a phosphor module for a laser light source. The present invention provides a phosphor module for a laser light source, which is characterized in that it includes: a heat sink; a phosphor layer configured on the upper side of the heat sink, and emits light of a wavelength different from the wavelength of the incident light after the light is incident; and a reflective layer , disposed around the upper surface of the phosphor layer in such a way as to reflect light, the phosphor layer has a protruding portion, and the protruding portion extends from the central portion of the phosphor layer between the reflective layers protruding between. According to the present invention, since the yellow light traveling toward the side of the phosphor layer can be reflected toward the front of the phosphor layer, the area of ​​the yellow ring can be minimized.

Description

technical field [0001] The present invention relates to a phosphor module for a laser light source. Background technique [0002] refer to figure 1 Generally, the vehicle 1 is provided with a lamp device 100 for stably ensuring the driver's viewing angle or notifying other vehicles of the driving state of the vehicle 1 when the surrounding illumination is low during driving. [0003] The vehicle light device includes: a headlight installed in front of the vehicle; and a tail light installed in the rear of the vehicle. The headlight is a lamp that illuminates the front to illuminate the front during night driving. Tail lights include: brake lights, which light up when the driver operates the brakes; and indicator lights, which inform the vehicle's direction of travel. [0004] refer to figure 2 , the laser light source 10 with high energy efficiency tends to be used in the vehicle lamp device 100 . In particular, since the light emitted from the laser diode has good str...
