Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a kind of fiber optic conduction laser of the present invention car light is described in detail.
The structural representation of a kind of fiber optic conduction laser car light that Fig. 1 provides, as shown in Figure 1:
A kind of fiber optic conduction laser car light, comprising:
Laser module 1, in order to Emission Lasers;
Optical fiber 2, is connected with described laser module 1, in order to transmit the described laser that described laser module 1 sends;
Reflector 5, is connected with described optical fiber 2;
Flourescent sheet 6, is arranged in described reflector 5, and described flourescent sheet 6 is above-mentioned is provided with fluorescent material.
Specifically, in the present embodiment, after laser module 1 sends laser, by optical fiber 2 by described Laser Transmission in reflector 5, because flourescent sheet 6 faces the interface that optical fiber 2 accesses reflector 5, so laser can be beaten on flourescent sheet 6.Due to flourescent sheet 6 being provided with fluorescent material, so laser can excite this fluorescent material thus produce the visible white light beam of human eye.Optimum, white light beam is via after a series of reflection process of reflector 5, and form collimated light beam 01, this collimated light beam 01 is launched through reflector 5.By this laser car lamp device, the white light beam that LASER Excited Fluorescence material produces obtains the less angle of departure after reflector 5 focuses on, thus improves the WBR distance of car light.
More excellent, in the present embodiment, described car light also comprises:
Fiber-optic output mouth 3, is arranged on one end of described optical fiber 2;
Optical fiber socket 4, is arranged on described reflector 5, and matches with described fiber-optic output mouth 3.
Wherein, one end of optical fiber 2 is connected with laser module 1, and the other end is connected with fiber-optic output mouth 3.In addition, fiber-optic output mouth 3 can match with optical fiber socket 4, and namely fiber-optic output mouth 3 can insert in optical fiber socket 4, to complete optical fiber 2 by laser transfer in reflector 5.It is worthy of note, in order to enable the irradiation of laser peak efficiency on flourescent sheet 6, to increase the intensity that fluorescent material produces white light beam, therefore preferred right opposite flourescent sheet 6 being arranged on optical fiber socket 4.This design, makes laser to be radiated at as much as possible on flourescent sheet 6, thus reduces the invalid laser exhaled, thus further increases the intensity that fluorescent material produces white light beam.
More excellent, in the present embodiment, described laser module 1 comprises some laser instruments 11, and namely described laser instrument 11 is all encapsulated in described laser module 1.Each described laser instrument 11 is all connected with described optical fiber 2, namely laser instrument 11 is all by described optical fiber 2 Emission Lasers, and the laser that laser instrument 11 sends can form the high-power blue laser of a branch of synthesis after being coupled via optical fiber 2, thus realize the output of high-power blue laser.In addition, the laser that described laser instrument 11 sends is 450nm blue wavelength, so output wavelength is the blue laser of 450nm after optical fiber 2 is coupled.
It is worthy of note, the reflector 5 of above-mentioned proposition can be the lamp body of car light, and namely reflector 5 can form lamp body.Because laser is entered in reflector 5 by optical fiber 2, and optical fiber 2 and the junction of reflector 5 just need corresponding syndeton, namely above-mentioned proposed fiber-optic output mouth 3 and optical fiber socket 4.Wherein, the model of described optical fiber socket 4 can adopt SMA905 adapter using as female, and corresponding fiber-optic output mouth 3 adopts SMA905 as male.Adopt male and the female of SMA905, make whole device have plug flexibly, be easy to dismounting and change.Laser after being coupled through optical fiber 2 enters after in reflector 5 via fiber-optic output mouth 3 and optical fiber socket 4, laser is radiated on flourescent sheet 6, owing to flourescent sheet 6 being coated with the fluorescent material that blue laser can excite, therefore after laser irradiates, produce the light of green section of reddish yellow, and combine with this blue light thus form macroscopic white light beam.
In the present embodiment, due to the effect of reflector 5, make through excite generation, white light beam that transmit direction is indefinite is formed as collimated light beam 01, thus makes this white light have good directionality.Because the transmit direction of collimated light beam 01 is unified, thus penetrability is strong, brightness is high.In addition, because laser module 1 and reflector 5 are kept apart by optical fiber 2, namely laser module 1 with transmitting cup-shaped become separation design, and laser module 1 and transmitting cup all can produce certain heat, separation design makes both intervals to regulate according to the actual requirements, thus improves the effect of heat radiation.In addition, achieve by fiber-optic output mouth 3 and optical fiber socket 4 optical fiber 2 that is connected with laser module 1 and launch freely plugging between cup, possessing better flexibility.
The using state schematic diagram of a kind of fiber optic conduction laser car light that Fig. 2 provides, as shown in Figure 2:
After this car light of unlatching, all laser instruments 11 in laser module 1 all start, and send the blue laser that wavelength is 450nm simultaneously.Because all laser instruments 11 are all connected with optical fiber 2, so optical fiber 2 can be coupled to the blue laser that laser instrument 11 sends, thus to form powerful, wavelength be the blue laser of 450nm.This powerful blue laser carries out transferring to optical fiber 2 and reflector 5 joint through optical fiber 2, and namely fiber-optic output mouth 3 and optical fiber socket 4 place, enter in reflector 5.Owing to being provided with flourescent sheet 6 at optical fiber socket 4 right opposite, so powerful blue laser can first be beaten on this flourescent sheet 6.In the present embodiment, this flourescent sheet 6 is coated with the fluorescent material that blue laser can excite, after laser irradiates, therefore produces the light of green section of reddish yellow, and combine with this blue light thus form macroscopic white light beam.
Because the direction of this white light beam is indefinite, if so directly using the light of untreated white light beam as car light, then its penetration power is not strong, and range can not reach ideal distance, poor effect.Therefore, in the present embodiment, car light Lamp cup can be set to reflector 5, the white light beam after exciting through a series of reflection process of reflector 5, can be formed a collimated light beam 01, thus makes this white light have good directionality.Because the transmit direction of collimated light beam 01 is unified, thus penetrability is strong, brightness is high.
In the present embodiment, by arranging multiple laser instrument 11 in laser module 1, and carry out coupling processing by the laser that optical fiber 2 pairs of laser instruments 11 send, thus improve the power of laser.Due to the lifting of the power of laser, the laser power of beating on flourescent sheet 6 is also promoted to some extent, and then the power of the light of green section of the reddish yellow produced because laser irradiates also strengthens, the power of the white light beam of formation also strengthens.Meanwhile, by regulating the position of flourescent sheet 6, making as much as possible to be radiated at the more powerful of the laser on flourescent sheet 6, the power of white light beam can be improved further.In addition, by a series of transmitting process of reflector 5, the white light beam making direction mixed and disorderly forms collimated light beam 01, thus improves penetrability and the brightness of white light beam.Finally, this collimated light beam 01 was thrown reflector 5 and was launched, and achieved the object of the long-range irradiation of car light.
In addition, in the present embodiment, one end of optical fiber 2 is connected with laser module 1, and the other end is connected with fiber-optic output mouth 3, and fiber-optic output mouth 3 can insert in the optical fiber socket 4 be arranged on reflector 5, thus achieves the connection of laser module 1 and reflector 5.Because fiber-optic output mouth 3 and optical fiber socket 4 are plug to design, so the car light that the present embodiment provides has more flexibility.In addition, due to the adjustability of optical fiber 2 length, achieve the adjustability of laser module 1 and reflector 5 distance, the distance namely between laser module 1 and reflector 5 can regulate according to actual actual conditions.Due to laser instrument 11 Emission Lasers, laser irradiates fluorescent material and the reflection processing procedure of white light in reflector 5 all can produce heat, therefore the separation design of laser module 1 and reflector 5 improves the radiating effect of two heating main bodies, thus improves the radiating effect of whole car light.
Generally speaking, a kind of fiber optic conduction laser car light that the present embodiment provides, has farther irradiation distance, and compared to traditional halogen regenerative-cycle headlamp, the light transmission of the car light that the present embodiment proposes specifically is doubled.This car light is connected by optical fiber 2, makes laser module 1 can be placed on place beyond car light, thus reaches better radiating effect.In addition, this Vehicle lamp structure is compact, facilitates plug optical fiber 2, is easy to change laser module 1.
