Description

Novel intelligent lamp module and application method thereof

Technical field

The invention relates to a vehicle lamp. In particular, the invention relates to a smart lamp module and an application method thereof. The dark area formed by the smart lamp module is only the size of the head of the opponent driver at different positions, and the other space still maintains high-brightness illumination when there is no target at all, so that the other party will not be dazzled.

Background technique

With the increasing safety of vehicles driving at night, more and more car-related manufacturers are developing new smart car lights technology. The so-called new smart car light technology is mainly a light-type variable headlight developed for the purpose of simultaneously realizing AFS and ADB functions.

For example, a headlight with ADB function, in conjunction with the vehicle's detection system. When detecting that other participants on the road (such as opposite, co-directional vehicles or pedestrians) are in a certain range of headlight illumination, the system can intelligently adjust the illumination brightness of the interval to avoid formation of the illuminated person. Dangerous glare, while no space for other road participants continues to maintain high brightness lighting. With such technical support, we can guarantee high-quality lighting in front of us (car drivers equipped with LED adaptive headlights) without any other participants on the road (such as vehicles or pedestrians in the same direction, in the same direction) Etc.) Dangerous glare to ensure safe driving at night on all sides of the road.

One of the existing solutions is the so-called MATRIX-based matrix headlights, which divides the illumination space of the entire headlight into different blocks, each block being made up of a different number of LEDs. Responsible for lighting, by extinguishing the LEDs of a particular block, a dark area of at least 1° can be provided.

However, including the above-mentioned matrix headlight technology solution, there is a common problem in the existing lamps with adjustable illumination range, that is, the minimum angle at which the system forms dark regions is still too large. That is to say, although the dark area formed can make the driver of the target vehicle not dazzling, the range of the dark area has already greatly exceeded the required vehicle width, which causes us to lose the illumination area. For example, the aforementioned matrix headlights can provide a dark area of at least 1°. The actual lateral width of the dark area depends on the distance between the target and us. For example, at 400 meters where ADB wishes to function, the width of the dark area is (400 m * tan 1 °) = 6.98 m, and the actual vehicle width ( Take the ordinary passenger car as an example) about 1.9 meters, obviously the dark area is too big.

The so-called ADB function, the most ideal situation is that the dark area formed by the smart headlights is only in the different position of the other driver. When the size of the head is set, the other space still maintains high-brightness illumination without the target, so that the other party will not be dazzled, and we can also illuminate any area on the driving route as much as possible.

Summary of the invention

The object of the present invention is to improve the above problems, and to provide a novel smart lamp module, wherein the headlight illumination of the novel smart lamp module uses high-resolution headlights.

The technical scheme of the optical module of a novel smart lamp of the invention is as follows:

A novel intelligent lamp module comprises: a laser source array, a laser collimation unit, a dynamic transmissive fluorescent wheel, a relay lens group, a DMD chip system and a projection lens group, wherein

The laser source array group includes a plurality of high power blue semiconductor laser components.

The laser collimating unit includes a lens corresponding to the number of the LED light sources to collect the light emitted by each laser light source, and collimate the laser light source into parallel light.

The moving and static transmissive fluorescent wheel will be generated by the laser light source array and irradiated on the incident surface of the fluorescent wheel, that is, the blue single-wavelength small spot on the front side, converted into a white composite spectrum that meets the illumination requirements of the vehicle lamp, and outputted on the back side of the fluorescent wheel.

The relay lens group is mounted on the light-emitting surface of the fluorescent wheel, that is, behind the back surface, and collects the Lambertian-distributed white light converted by the fluorescent wheel, and illuminates the DMD chip behind the relay lens group.

The DMD chip is a microelectromechanical system (MEMS) for implementing electronic input and optical output, and performs spatial light modulation.

The projection lens group magnifies and projects the DMD-modulated light to form the final illumination pattern of the vehicle lamp.

According to the present invention, the collimated light rays incident in the left and right directions are all reflected in the same direction by the mirror mirror array mounted in front of the lens, that is, the light emitted by all the lasers is all collimated into parallel light in the same direction. The laser collimating unit enters the converging lens group along the optical axis of the converging lens group mounted above the module. The light from all of the lasers is concentrated by a converging lens group at a point on the front side of the fluorescent ceramic.

According to the invention, the output spot spatial energy distribution is a Lambertian type. At the same time, due to the relatively large laser irradiation power, the dynamic rotating fluorescent wheel scheme is adopted to prevent the laser from being damaged by the laser irradiating the same point for a long time.

The size of the white spot on the back of the fluorescent wheel corresponds to the laser spot that is incident on the front side, but is much smaller than the size of the DMD work surface. The relay lens group is designed to enlarge the white spot on the back of the fluorescent wheel and image it on the working surface of the DMD chip. The size meets the requirements of the DMD working surface, and the light is prevented from being irradiated to the area outside the working surface to improve the efficiency.

The DMD chip is a micro-electromechanical system (MEMS) developed and manufactured by Texas Instruments to implement electronic input and optical output. Developers can use this system to perform high-speed, efficient and reliable spatial light modulation.

A novel smart lamp module according to the present invention is characterized in that the laser collimating unit is installed The coated mirror array in front of the collimating lens reflects all the collimated rays from the left and right directions in the same direction, that is, the light emitted by all the lasers is collimated into parallel light of the same direction, and is mounted along the die. The optical axis of the converging lens group above the group enters the converging lens group located in front of the relay lens group, and the light emitted from all the lasers is concentrated by a converging lens group at a point on the front surface of the fluorescent ceramic of the converging lens group.

A novel smart lamp module according to the present invention is characterized in that the laser light source array group comprises 16-42 high power blue semiconductor laser elements.

The light source unit of the vehicle light flux light source module is formed from the laser light source array to the fluorescent wheel, and the luminous flux thereof is more than 13,000 lumens.

A novel smart lamp module according to the present invention is characterized in that when a certain pixel in the working surface of the DMD is in an "on" state, the light passing through the relay lens group is used by the DMD. The reflection of a particular pixel enters the entrance pupil of the projection lens group, thereby being projected by the projection lens group (on the screen) to form a lit pixel, and if a pixel is in the "off" state, then the illumination will be illuminated thereon. The light is reflected into the light absorber disposed within the DMD chip system, and since the light on the pixel is not received by the projection lens group, corresponding dark pixels are formed (on the screen).

Specifically, when a certain pixel in the working surface of the DMD is in an "on" state, the light passing through the relay lens group is reflected by the specific pixel on the DMD into the entrance pupil range of the projection lens group, thereby Projected by the projection lens group (on the screen) forms a lit pixel. If a pixel is in the "off" state, the light illuminating it will be reflected into the light absorber disposed in the DMD chip system, since the light on the pixel is not received by the projection lens group, (on the screen Correspondingly, dark pixels are formed.

In accordance with the present invention, each DMD contains up to 2 million independently controlled micromirrors (built on corresponding CMOS memory cells).

Each DMD contains up to 2 million independently controlled micromirrors (built on the corresponding CMOS memory cells). During operation, the DMD controller loads a "1" or a "0" for each basic storage unit. A mirror reset pulse is then applied, which causes each micromirror to deviate from approximately one hinge to achieve a corresponding +/- 12° state. Since the physical stop is caused by the resistance of the two spring thimbles, the deviation angles of the two effective states are repeatable. In the projection system, the +12° state corresponds to the "on" pixel, and the -12° state corresponds to the "off" pixel. Grayscale graphics are created by programming the on/off duty cycle of each lens, and multiple light sources can be multiplexed to create an RGB full color image. In other applications, the +/-12° state provides a graphic and its reverse pattern for the two general purpose output ports.

According to the features of the present invention, the working distance of the original three lenses is longer, reaching 98 mm. If they are sequentially deployed, the valuable space in the lamp is occupied. If the original relay lens group has a projection size of 81*55 mm at a plan view angle, the projection size of the relay lens group will be reduced to 61*38 mm by adding a mirror at an appropriate position and folding the entire optical path.

According to the present invention, in order to achieve the same effect, the lens can be combined in various combinations, and the key is to realize the above-mentioned task of magnifying and imaging the white spot behind the fluorescent wheel to the DMD working surface, and the current design magnification is 4.12 times.

The moving and static transmissive fluorescent wheel will be generated by the laser light source array and irradiated on the incident surface of the fluorescent wheel, that is, the blue single-wavelength small spot on the front side, along the optical axis of the converging lens group mounted above the unit, into the relay lens group. In the previous converging lens group, the light emitted by all the semiconductor lasers is concentrated by a converging lens group at a point on the front surface of the fluorescent ceramic of the converging lens group to obtain a blue light spot of high optical power, the spot size being 1.6-1.8 mm 2 . , optical power 50-70W,

Converted to a white composite spectrum that meets the needs of headlight illumination, output on the back of the fluorescent wheel,

The relay lens group is mounted on the light exit surface of the fluorescent wheel, that is, behind the back side, and the Lambertian distribution white converted by the fluorescent wheel Light is collected and illuminated on the DMD chip behind the relay lens group,

A novel smart lamp module according to the present invention is characterized in that the laser collimating unit shoots a laser light source array of a rectangular frame in two directions by a coated mirror array mounted in front of the collimating lens. The collimated light rays are all reflected in the same direction, that is, all the light emitted by the semiconductor lasers are collimated into parallel light of the same direction, along the optical axis of the converging lens group mounted above the unit, into the front of the relay lens group. Converging the lens group, the light emitted by all the semiconductor lasers is concentrated by a converging lens group at a point on the front surface of the fluorescent ceramic of the converging lens group to obtain a blue light spot of high optical power, the spot size is 1.6-1.8 mm 2 , light Power 50-70W.

The projection lens group forms a dark pixel; the reflected light on the finally open pixel will enter the projection lens group and be projected to form the light and dark illumination pattern required for the smart car headlight, as shown in FIG.
