Description
Technical Field
The invention relates to the technical field of detection lighting systems, in particular to a car lamp module for detection lighting and a detection lighting system.
Background
At present, with the development of technology, the car lamp has basic illumination functions, and also has the functions of laser radar detection, ranging, recognition and perception, SLAM (simultaneous localization AND MAPPING, instant positioning and map building) and the like.
In a vehicle lamp having both an illumination function and a lidar function, two different functions are generally implemented by emitting light beams of two different wavelengths, respectively, and the lidar generally uses laser light of invisible infrared wavelength. The light beams with two different wavelengths can be respectively emitted by two different light sources, but the two light sources respectively emit light beams which occupy a larger space, so that the internal structure layout of the car lamp is not facilitated. In order to solve the above problems, a part of the vehicle lamp adopts a light source to emit light, the emitted light is split by a beam splitter, the split part of the light is converted into visible white light by a conversion element for illumination, and the other part of the light split by the beam splitter is emitted and used as detection light for laser detection or ranging.
However, the beam splitter (such as a prism) is used for spatial light splitting, so that the dispersion performance of the beam splitter and the spatial position of the beam splitter need to be strictly designed, so that corresponding wave band parts in two beams of light can be accurately incident into corresponding light paths respectively, and otherwise the measurement accuracy of a detection part is affected. Therefore, the precision requirement of the process for the production and assembly processes of the car lamp in the prior art is extremely high, so that the production and assembly efficiency of the car lamp is low and the yield is low.
Disclosure of Invention
The invention aims to provide a lamp module for detecting illumination, which solves the technical problem that the process accuracy requirements of the production and assembly processes of the lamps in the prior art are extremely high.
The invention provides a lamp module for detecting and lighting, which comprises: a laser light source, a driving device and a conversion device,
The conversion device is provided with a fluorescence area and a transmission area;

The light emitted by the laser light source irradiates the fluorescent region to generate first light for illumination, and the light emitted by the laser light source irradiates the transmission region to generate second light for detection of the target object.
In the above technical solution, further, the laser light source has an emitting end for emitting visible light wavelength light.
In the above technical scheme, further, the conversion device is a fluorescent wheel, a through hole is formed in the fluorescent wheel, the through hole is the transmission area, and the driving device drives the fluorescent wheel to rotate.
In any of the above embodiments, further, the transmissive region is provided with a light homogenizing plate.
In any of the above embodiments, further, when the light of the laser light source is incident on the transmission region in the conversion device, the laser light source is in a pulse driving mode.
In the above technical solution, further, the fluorescent wheel is a reflective fluorescent wheel or a transmissive fluorescent wheel.
In any of the above technical solutions, further, the conversion device is a rectangular plate, and the driving device drives the rectangular plate to perform linear reciprocating movement.

In the above technical solution, further, a detection point of the position sensor is disposed at an edge of the conversion device.
Compared with the prior art, the lamp module for detecting and lighting has the following advantages:
in the lamp module for detection illumination, the driving device drives the conversion device to move at high speed, so that the laser light source sequentially and alternately irradiates the fluorescent region and the transmission region, and light splitting is performed. When the illuminated area is a fluorescent area, the light generates a first light in the fluorescent area of the conversion device for illumination. When the irradiated area is a transmission area, the emitted light is second light, and the second light is used for visible laser radar detection.
In the vehicle lamp module for detection illumination, the light splitting of the illumination part and the detection part can be realized only by the conversion device being positioned in the area where the laser light source can irradiate, and high requirements on the relative position between the conversion device and the laser light source do not exist, and even if errors occur in the production or assembly process of the conversion device and the laser light source, the errors are insufficient to influence the detection precision. Therefore, the vehicle lamp with the lamp module for detecting and lighting provided by the application has relatively low requirements on production and assembly precision, so that the production and assembly efficiency of the vehicle lamp are improved.
In addition, the structure of the lamp module for detecting and lighting provided by the application is more compact.
Further, as the laser light source adopts visible light laser for illumination of the car lamp, illumination of the car lamp and detection of a laser radar are realized at the same time. That is, the laser radar detection part is different from the traditional laser light source adopting infrared wavelength laser, and adopts the laser light source of visible wavelength.
Another object of the present invention is to provide a detection lighting system, so as to solve the technical problem that the process accuracy requirements of the production and assembly processes of the vehicle lamp in the prior art are very high.
In order to achieve the above purpose, the technical scheme of the invention is realized as follows:

The advantage that the detection lighting system and the above-mentioned detection lighting lamp module have for prior art is the same, and this is not repeated here.

The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Example 1
As shown in fig. 1 to 8, a lamp module for detecting illumination according to an embodiment of the present invention includes: a laser light source 10, a driving device 30 and a conversion device 20, wherein: the conversion device 20 is provided with a fluorescent region 21 and a transmissive region 22. The driving device 30 is connected to the conversion device 20 for driving the conversion device 20 to move so that the fluorescent region 21 and the transmissive region 22 are alternately located in the optical path with the laser light source 10. The light emitted from the laser light source 10 irradiates the fluorescent region 21 to generate a first light for illumination, and the light emitted from the laser light source 10 irradiates the transmissive region 22 to generate a second light for detection of the target object. Specifically, the fluorescent region 21 is provided with a phosphor.
For convenience of description, the area of the conversion device 20 irradiated by the laser light source 10 will be referred to as an irradiation area.
In a preferred implementation of this embodiment, the laser light source has an emitting end for emitting visible light wavelength, and the specific emitted laser is blue laser with a wavelength of about 450 nm.
In particular, the driving device 30 drives the conversion device 20 to move at a high speed, so that the fluorescent region 21 and the transparent region 22 continuously and alternately appear in the irradiation region, and when the irradiation region is the fluorescent region 21, the light generates a first light in the fluorescent region 21 of the conversion device 20, specifically, the first light is a visible white light formed by the fluorescent powder penetrating the fluorescent region 21 by the blue laser, and the first light is used for illumination. When the irradiation area is the transmission area 22, the emitted blue laser light is a second light, and the second light is used for detection.
Since the fluorescent region 21 and the transparent region 22 are alternately located in the illumination region, the light emitted from the lamp module for detecting illumination is alternately changed between the first light and the second light, and since the conversion device 20 is driven by the driving device 30 to move at a high speed, the resolution of human eyes is insufficient to distinguish the intermittently emitted first light, i.e. the first light is emitted as if it were continuously emitted in human eyes.
In the lamp module for detecting and lighting provided in this embodiment, there is no high requirement on the relative position between the conversion device 20 and the laser light source 10, and even if an error occurs between the conversion device 20 and the laser light source 10 in the production or assembly process, the error is not enough to affect the detecting precision. Therefore, the vehicle lamp with the vehicle lamp module for detection illumination provided by the embodiment has relatively low requirements on production and assembly precision, so that the production and assembly efficiency of the vehicle lamp are improved.
In a preferred implementation of this embodiment, the conversion device 20 has the following structure: the conversion device 20 is a fluorescent wheel, through holes are formed in the fluorescent wheel, the through holes are transmission areas 22, and the driving device 30 drives the fluorescent wheel to rotate. The drive device 30 may be a high speed motor.
Further, a light homogenizing plate is arranged at the through hole. The light-homogenizing plate can diffuse the point laser emitted from the laser light source 10 into a surface laser.
In this embodiment, the laser source 10 is a blue laser diode, the emitted laser is blue laser, and in the rotation process of the fluorescent wheel, the distribution of blue laser pulses emitted by the lamp module for detecting illumination is as shown in fig. 7, the 450nm duty ratio is larger, the power is higher, the pulse width is short, namely, the blue pulses occur at intervals. As can be seen from fig. 7, the first light and the second light are emitted at intervals.
The fluorescent wheel may be a reflective fluorescent wheel or a transmissive fluorescent wheel. The fluorescent wheels presented in the drawings provided by the application are all transmissive fluorescent wheels. When the fluorescent wheel is a reflective fluorescent wheel, the laser light source 10 may be moved to the reflective end.
The above-mentioned fluorescent wheel adopts a rotation mode to change the positions of the fluorescent region 21 and the transmitting region 22, and other modes can be adopted to change the positions of the fluorescent region 21 and the transmitting region 22 relative to the laser light source 10.
For example, the positions of the fluorescent region 21 and the transmissive region 22 may also be changed by linear reciprocation, and in this embodiment, the conversion device 20 preferably adopts a rectangular plate, and the driving device drives the rectangular plate to perform linear reciprocation. On the rectangular plate, the fluorescent region 21 and the permeation region 22 are sequentially arranged along the length direction of the rectangular plate, and the driving device 30 drives the rectangular plate to reciprocate along the length direction. Preferably, the fluorescent region 21 on the rectangular plate has a larger ratio than the transmissive region 22.
On a rectangular plate, the fluorescent region 21 may be one continuous region and the transmissive region 22 another continuous region. Or on the rectangular plate, the number of the fluorescent areas 21 and the transparent areas 22 is plural, and the fluorescent areas 21 and the transparent areas 22 are alternately arranged along the length direction of the rectangular plate.
Further, a light homogenizing plate is provided at the transmission area 22 of the rectangular plate. Specifically, the rectangular plate may be formed by splicing a fluorescent plate and a light homogenizing plate, where the fluorescent plate is a fluorescent region 21 and the light homogenizing plate is a transparent region 22. Or the main body of the rectangular plate is a fluorescent plate, an opening is arranged on the fluorescent plate, and a light homogenizing plate is embedded in the opening.
In a preferred implementation of this embodiment, when the light of the laser light source 10 is incident on the transmission region 22 in the conversion device 20, the laser light source 10 is in a pulse driving mode to form a transient high-power short-pulse-width narrow pulse, and such high-power pulse can realize a further-distance detection.
To facilitate detection of the position of the transmissive region 22 to pulse the laser source 10 as light is directed to the transmissive region 22, in one embodiment, a position sensor is used to detect the position of the fluorescent region 21 or the position of the transmissive region 22, and if the transmissive region 22 is moved to the position of the illuminated region, the driving mode of the laser source 10 is changed to pulse; when the fluorescent region 21 moves to the position of the irradiation region, the driving mode of the laser light source 10 is changed to continuous driving.
The detection point of the position sensor is disposed at the edge of the conversion device 20, and the position sensor further includes a detection mechanism. In particular, the detection point may be a bump 50, and the light emitted by the laser light source 10 irradiates the end face of the conversion device 20, and the bump 50 is disposed on the side face of the conversion device 20. During rotation of the conversion device 20, the bump 50 moves with the conversion device 20, and when the detection mechanism detects the bump 50, it represents that the transmission area 22 of the conversion device 20 is in the irradiation area. The position sensor may specifically be a photodetector or an electromagnetic sensor. When a photodetector is used, the photodetector determines whether the bump 50 is moved in place according to a change in luminous flux during the movement of the bump 50. When the electromagnetic sensor is adopted, the bump 50 is a magnetic element, the detection mechanism is provided with a hall element, and in the moving process of the bump 50, the distance between the bump 50 and the detection mechanism is changed, so that the magnetic field is changed, and the hall element judges the position of the bump 50 according to the change of the magnetic field, so as to judge the position of the transmission area 22.
Further, as shown in fig. 1-3, the vehicle lamp module for detection illumination further includes a protective housing 40, the laser light source 10, the conversion device 20 and the driving device 30 are all disposed inside the protective housing 40, the protective housing 40 is provided with a light outlet 43, and the first light and the second light are emitted from the protective housing 40 through the light outlet 43.
In order to facilitate the installation of the laser light source 10, the conversion device 20 and the driving device 30 inside the protective housing 40, the protective housing 40 includes a base 41 and a top cover, the base 41 and the top cover are fixedly connected by bolts, the laser light source 10, the conversion device 20 and the driving device 30 are all installed on the base 41, and the light outlet 43 is arranged on the top cover. After the installation, the top cover is fastened, and the top cover is fixed to the base 41 by bolts.
To facilitate assembly of the protective housing 40 into a vehicle, one mounting seat 42 is provided on each of opposite sides of the outside of the protective housing 40, and mounting holes are provided in the mounting seat 42.

The optical receiving device is preferably an area array receiving device based on a CMOS or CCD process, and may be a photodiode such as an APD (AVALANCHE PHOTO DIODE ), a PIN diode, or SPAD (Single Photon Avalanche Diode ). The second light emitted by the car light module is received by the optical receiving device after being reflected by an object.

Further, the detection illumination system further includes a reflector 72 and a lens 71, and the light emitted from the lamp module is reflected by the reflector 72 and then emitted through the lens 71.
