Embodiments of the invention

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and Not all embodiments. Based on the embodiments of the present invention, one of ordinary skill in the art All other embodiments obtained without creative efforts are within the scope of the present invention.

[0020] Please refer to FIG. 1 and FIG. 1 together for a schematic structural view of a first embodiment of a lighting device of the present invention. The illumination device 10 includes an excitation light source 11, a first concentrating element 12, a beam deflecting device 13, a beam splitter 14, and a wavelength converting device 15 and a second concentrating element 16.

[0021] wherein the excitation light source 11 is used to transmit the excitation light beam to the first concentrating element 12. In a specific embodiment of the present invention, the excitation light source 11 may be a blue laser or an ultraviolet laser. Compared with the traditional lighting devices using LED lamps, xenon lamps and halogen lamps as the light source, the laser is used as the illumination method, which has high brightness and long service life, and the beam emitted by the collimating angle of the laser beam can be compared. Concentrated emission in one direction can greatly increase the distance of illumination. At the same time, if the direction of the laser beam is properly adjusted, the rut beam can be avoided to hit the opposite car, which improves the safety of driving. In this embodiment, a blue laser is used as the excitation light source.

[0022] The first concentrating element 12 is configured to converge the received excitation light, and transmit the concentrated excitation light to the beam deflecting device 13. The first concentrating element 12 used in this embodiment is a positive lens. Of course, in other embodiments, a wedge-shaped microlens, a spherical microlens or a conical microlens may be used, and all of the excitation light source 11 is emitted. The excitation beam is concentrated. Further, the illumination device 10 may further include a first collimating device A disposed between the excitation light source 11 and the first concentrating element 12 for performing the excitation light emitted by the excitation light source 11 first. The collimation process is performed to obtain parallel light, and the parallel light is further transmitted to the first concentrating element 12.

The beam deflecting device 13 used in the present embodiment is used for deflecting the focused excitation beam by a certain angle and transmitting it to the beam splitter 14. Further, the beam deflecting means 13 adjusts the direction in which the concentrated light is deflected. In the present embodiment, the beam deflecting device 13 can be driven to rotate by a certain angle by electro-optical, acousto-optic, magneto-optical, etc., so that the excitation light is deflected by the beam deflecting device 13 and then deflected by a certain angle.

[0024] The beam splitter 14 is configured to reflect the deflected blue excitation beam to the wavelength conversion device 15. Specifically, the beam splitter used in the present application has a very small area and is capable of reflecting the excitation beam emitted by the excitation source and transmitting the light of other wavelength bands. Moreover, the deflection angle of the beam splitter 14 is adjustable to be compatible with the angle of the excitation light passing through the beam deflecting device 13. Specifically, the beam splitter 14 is capable of adjusting excitation light incidence to wavelength conversion The angle of the device 15 facilitates the incidence of excitation light to a particular location of the wavelength conversion device 15. The deflection angle adjustment of the beam splitter 14 used in this embodiment can also be realized by electro-optical, acousto-optic or magneto-optical.

[0025] Further, the illumination device 10 further includes a second concentrating element 16 disposed between the beam splitter 14 and the wavelength conversion device 15 for transmitting the deflected excitation light to the wavelength conversion The device 15 and the illumination light output by the wavelength conversion device 15 are concentrated.

The wavelength conversion device 15 is for absorbing a part of the excitation light to form a laser light, and the laser light and the excitation light not absorbed by the wavelength conversion device 15 form an illumination light to be emitted. Optionally, the side of the wavelength conversion device 15 facing away from the second concentrating element 16 is plated with a reflective film B, and the reflectance distribution of the reflective film B is not uniform, and the reflective film B is used for receiving the laser light and not being wavelength. The excitation light absorbed by the conversion device 15 is reflected to the second concentrating element 16, and the second condensing element 16 collects and collects the laser light and the excitation light to be emitted. Alternatively, the reflective film B coated by one side of the wavelength conversion device 15 facing away from the second concentrating element 16 may be a material having a non-uniform reflectance. In other embodiments, a plurality of reflective films having different reflectances may be formed. Specifically, a plurality of regions may be disposed on a surface of the wavelength conversion device 15 facing away from the second light collecting member 16, and different regions are reflected. The reflectivity of the film is different, that is, the material of the reflective film in different regions can be set to be different, so that the reflectances of different regions are different. Specifically, a partial region of the reflective film B is a material having a high reflectance, and a partial region is a material having a low reflectance. Normally, 激发, the excitation light illuminates the phosphor segment corresponding to the portion with the higher reflectance, so that the laser light and the unabsorbed excitation light are incident on the region of the high reflectance material, so that the reflected film B reflects the laser light and The absorbed excitation light forms an illumination light to exit; when the nighttime car or rainy weather needs to adjust the illumination light color temperature, the deflection angle of the excitation light can be adjusted, so that the excitation light is irradiated to the phosphor corresponding to the portion with a lower reflectance. a segment such that the laser light and the unabsorbed excitation light are incident on the region of the low-reflection material, so that light of a part of the wavelength band is transmitted through the region of the low-reflection material, thereby weakening the energy of the portion of the wavelength band, thereby reducing the intensity of the illumination light or Adjust the color temperature of the illumination light.

[0027] It can be understood that, in other embodiments, the reflective film B may also be formed by splicing and combining reflective films of different reflectivity.

[0028] It can be understood that, in other embodiments, the low reflection area of the reflective film B may also be disposed on a side of the wavelength conversion device 15 facing the second light collecting element 16, thereby weakening the excitation light to be irradiated on the wavelength conversion material. The intensity of light is used to achieve the purpose of adjusting the intensity of the emitted light and the color temperature. [0029] Further, the phosphor on the wavelength conversion device 15 may specifically be a yellow phosphor, and the yellow light is excited by the excitation light source to emit blue light, and the blue excitation light beam is mixed with the unexcited phosphor to obtain white illumination light.

[0030] In other embodiments of the present invention, when the excitation light source is an ultraviolet laser, the phosphor on the wavelength conversion device is at least two colors, specifically, a red, green, and blue primary color phosphor, which is in the excitation light source. The phosphor is excited by the ultraviolet light, and is mixed with the ultraviolet excitation beam of the unexcited phosphor to obtain white illumination. Of course, it can also be two complementary color phosphors, such as yellow + blue phosphor, magenta + green phosphor, red + cyan phosphor, excited by ultraviolet light, and ultraviolet excitation with unexcited phosphor. The beam is mixed to obtain white light illumination.

[0031] Now the specific principle of the lighting device is divided into two cases, as follows:

[0032] 1) The beam deflecting device does not change the direction of its transmitted beam

[0033] The excitation light source 11 used in the present application is a blue laser. Of course, in other embodiments, an ultraviolet laser may also be used. The blue excitation beam emitted by it is concentrated by the first concentrating element 12 and transmitted to the beam deflecting device 13, and the first concentrating element 12 can be a positive lens. Thereafter, the beam deflecting device 13 does not deflect, and the excitation beam condensed by the beam deflecting device 13 is irradiated onto the beam splitter 14. The area of the beam splitter 14 is very small, and the blue light can be reflected and transmitted through other wavelength bands. After the blue excitation light is reflected, it is concentrated on the wavelength conversion device 15 through the second concentrating element 16 to excite the yellow fluorescence, and the side of the wavelength conversion device 15 facing away from the second concentrating element 16 is plated with uneven reflectivity. The distributed film is such that both the stimulated fluorescence and the unabsorbed blue excitation light are reflected toward the second concentrating element 16, collected by the second concentrating element 16 and directed toward the beam splitter 14, and transmitted to form illumination light.

[0035] 2) The beam deflecting device changes the direction of its transmitted beam

[0036] wherein the beam deflecting device 13 changes the direction of its transmitted beam to be adjustable, and can deflect a plurality of angles as needed. Further, the blue excitation beam emitted from the excitation source 11 is concentrated by the first concentrating element 12 and transmitted to the beam deflecting device 13, and the beam deflecting device 13 deflects the transmitted blue excitation beam by a small angle as shown in FIG. The deflected blue excitation beam is reflected by the beam splitter 14 and is incident on the other position of the wavelength conversion device 15 after passing through the second concentrating element 16 due to the deflection angle. The position-excited fluorescence is also deflected by the second concentrating element 16 and is deflected by a certain angle. After being transmitted by the beam splitter 14, the outgoing beam is angled with respect to the output beam of the beam deflecting device 15 without changing the direction of the transmitted beam. The deflection, therefore, by controlling the angle at which the beam splitter 14 is deflected, the direction of the output beam can be adjusted.

[0037] As shown in FIG. 3, after the beam deflecting device deflects the beam, the spot position of the blue light on the wavelength converting device 15 also changes.

Not uniform. When a blue spot is irradiated on the reflective film, a part of the blue light is transmitted, a part of the light is reflected and the white light is synthesized with the excited fluorescence, so the energy of the output beam is also unevenly distributed, the energy in a certain direction is low, and the energy in a certain direction Relatively high. In a specific application scenario of the present invention, for example, driving at night, smog weather, etc., by controlling the beam deflecting device 13 to change the illumination direction and energy distribution of the output light, it is possible to prevent the glare from being irradiated into the eyes of the opponent driver.
