Embodiment Construction

[0010] figure 1 It is a structural schematic diagram of the first embodiment of the laser light source module of the present invention, such as figure 1 As shown, the laser light source module includes a laser diode 101 , a filter 103 , a first focusing lens group 104 , a second focusing lens group 105 , a fluorescent layer 106 , and an LED 107 . The laser diode 101, the first focusing lens group 104, and the fluorescent layer 106 are arranged on one side of the optical filter 103, the second focusing lens group 105, and the LED 107 are arranged on the other side of the optical filter 103, and the first emitted from the laser diode 101 A light beam 102 is reflected by the optical filter 103 and enters the reflection light path, and the first focusing lens group 104 of the reflection light path focuses the first light beam 102 onto the fluorescent layer 106 . The fluorescent layer 106 is arranged on a reflective substrate. The fluorescent layer 106 can absorb the laser light e...

Abstract

The invention provides a laser light source module group comprising a laser diode, a light filter, a first focusing lens group, a second focusing lens group, a fluorescent layer and an LED. A first light beam emitted out of the laser diode is firstly reflected by the light filter and then converged and incident to the fluorescent layer through the first focusing lens group; the fluorescent layer absorbs the first light beam and emits a second light beam having different wavelength from that of the first light beam; and the LED is arranged at the other side of the light filter relative to the incident first light beam, and light emergent out of the LED is converged through the second focusing lens group and then reflected by the light filter so as to form a third light beam, wherein driving current the laser diode and the LED can be respectively controlled. The proportion of two types of light in the final output light can be controlled through circuit control so as to adjust color temperature of the output light.

Description

technical field [0001] The invention relates to the field of laser light sources, in particular to a laser light source module and a laser light source system using the module. Background technique [0002] At present, LED light sources are replacing traditional incandescent lamps and energy-saving lamps as a new type of lighting source. As a general lighting source, it has the advantages of high efficiency, energy saving, environmental protection and long life. However, the brightness of LEDs is limited. In some special application fields that require high-brightness light sources, such as stage lighting, car headlights, and projection displays, LEDs cannot meet the requirements. The semiconductor laser diode with the same source as LED also has the advantages of high efficiency, energy saving, environmental protection and long life. Using laser excitation phosphor technology (remote phosphor technology) can obtain a point light source with small etendue and high brightness...
