Example one
As shown in fig. 1-8, the embodiment of the utility model provides a lamp module for detection illumination includes: laser light source 10, driving device 30 and conversion device 20, wherein: the conversion means 20 is provided with a fluorescent area 21 and a transmissive area 22. The driving device 30 is connected to the conversion device 20 for driving the conversion device 20 to move, so that the fluorescent regions 21 and the transmissive regions 22 are alternately located in the optical path with the laser light source 10. The light emitted from the laser source 10 irradiates the fluorescent region 21 to generate a first light for illumination, and the light emitted from the laser source 10 irradiates the transmissive region 22 to generate a second light for detecting the target object. Specifically, the fluorescent region 21 is provided with phosphor.
For convenience of description, a region irradiated with the laser light source 10 on the conversion device 20 is referred to as an irradiation region.
In a preferred embodiment of this embodiment, the laser light source has an emitting end for emitting visible light wavelength light, and specifically, the emitted laser light is blue laser light with a wavelength of about 450 nm.
In specific implementation, the driving device 30 drives the conversion device 20 to move at a high speed, so that the fluorescent region 21 and the transmissive 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 a blue laser penetrating through a phosphor in the fluorescent region 21, and is used for illumination. When the irradiation region is the transmissive region 22, the emitted blue laser light is the second light, and the second light is used for detection.
Since the fluorescent area 21 and the transparent area 22 are alternately located in the irradiation area, the light emitted by 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 not enough to distinguish the first light emitted discontinuously, that is, the first light is emitted like uninterrupted in human eyes.
In the lamp module for probing and lighting provided by the embodiment, there is no high requirement for the relative position between the conversion device 20 and the laser light source 10, and even if an error occurs in the production or assembly process of the conversion device 20 and the laser light source 10, the error is not enough to affect the accuracy of probing. Therefore, the requirements on production and assembly precision of the vehicle lamp using the lamp module for detection and illumination provided by the embodiment are relatively low, so that the production and assembly efficiency of the vehicle lamp is improved.
In a preferred embodiment of the present embodiment, the switching device 20 has the following structure: the conversion device 20 is a fluorescent wheel, a through hole is formed in the fluorescent wheel, the through hole is a transmission area 22, and the driving device 30 drives the fluorescent wheel to rotate. The drive device 30 may be a high-speed motor.
Furthermore, a light homogenizing plate is arranged at the through hole. The light homogenizing plate can diffuse the point laser light emitted by the laser light source 10 into surface laser light.
In this embodiment, the laser light 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 detection and illumination is as shown in fig. 7, the duty ratio of 450nm is larger, the power is higher, the pulse width is very short, namely the blue pulse, and the blue pulse appears at intervals. As can be seen from fig. 7, the first light ray and the second light ray are emitted at intervals.
The fluorescent wheel may be a reflective fluorescent wheel or a transmissive fluorescent wheel. The fluorescent wheels presented in the figures provided in this application are all transmissive fluorescent wheels. When the fluorescent wheel is a reflective fluorescent wheel, the laser light source 10 is moved to the reflective end.
The fluorescent wheel changes the positions of the fluorescent regions 21 and the transmissive regions 22 by rotating them, and in addition, the positions of the fluorescent regions 21 and the transmissive regions 22 with respect to the laser light source 10 may be changed by other methods.
For example, the positions of the fluorescent area 21 and the transparent area 22 can be changed by linear reciprocating movement, in this embodiment, the converting device 20 is preferably a rectangular plate, and the driving device drives the rectangular plate to perform linear reciprocating movement. On the rectangular plate, the fluorescent region 21 and the transparent 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 area 21 is larger than the transmissive area 22 on the rectangular plate.
On a rectangular plate, the fluorescent area 21 can be one continuous area, and the transmissive area 22 can be another continuous area. Alternatively, the number of the fluorescent regions 21 and the transmissive regions 22 is plural in the rectangular plate, and the fluorescent regions 21 and the transmissive regions 22 are alternately arranged in the longitudinal direction of the rectangular plate.
Further, a light uniformizing plate is provided in the transmissive region 22 of the rectangular plate. Specifically, the rectangular plate may be formed by splicing a fluorescent plate and a dodging plate, where the fluorescent plate is a fluorescent region 21, and the dodging plate is a transmissive 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 at the opening.
In a preferred embodiment of the present embodiment, when the light from the laser source 10 is incident on the transmissive region 22 of the conversion device 20, the laser source 10 is in a pulse driving mode to form a short pulse with a short pulse width and a high power at a moment, such that the high power pulse can be detected at a longer distance.
In order to facilitate detection of the position of the transmissive region 22 and to pulse-drive the laser light source 10 when light is emitted 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 when the transmissive region 22 is moved to the position of the irradiation region, the driving method of the laser light source 10 is changed to pulse-drive; when the fluorescence area 21 moves to the position of the irradiation area, the driving method of the laser light source 10 is changed to continuous driving.
The detection point of the position sensor is arranged at the edge of the switching device 20, and the position sensor further comprises a detection mechanism. In a specific implementation, the detecting point may be a bump 50, the light emitted from the laser source 10 irradiates the end surface of the converting device 20, and the bump 50 is disposed on the side surface of the converting device 20. During the rotation of the converting device 20, the projection 50 moves along with the converting device 20, and when the detecting mechanism detects the projection 50, it represents that the transmission area 22 of the converting device 20 is in the irradiation area. The position sensor may in particular be a light detector or an electromagnetic sensor. When the photo detector is used, the photo detector judges whether the bump 50 is moved in place according to the change of the luminous flux during the movement of the bump 50. When the electromagnetic sensor is used, the bump 50 is a magnetic element, the detection mechanism is provided with a hall element, the distance between the bump 50 and the detection mechanism changes during the movement of the bump 50, so that the magnetic field changes, 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 region 22.
