However, in the optical system in the prior art, which uses one optical system to realize function multiplexing of a plurality of signal lamps, greeting lamps, and lamps in combination thereof, there are at least two light sources with different types to realize different functions, but this inevitably results in defocusing of both light sources, or one light source is located at a focus, the other light source is defocused, and at least one light source of the whole optical system is defocused. If the light source is out of focus, the lighting uniformity of the corresponding function will have defects.

In view of the above problems, many conventional solutions aim to optimize the design of an optical system, and are intended to reduce uneven lighting due to defocus. Even the light source suppliers provide dual-chip or multi-chip light sources, so as to reduce the distance between multiple light sources and reduce the defocusing distance of the light source of the whole optical system. However, these methods only reduce the unevenness caused by defocusing of the light source as much as possible, and make up for the defect of optical uniformity, and do not essentially and completely solve the problem of the defect of uniformity of lighting caused by defocusing of at least one light source inevitably existing when one optical system realizes the multi-functional multiplexing of the car light. Therefore, the method for realizing multifunctional lighting based on electromechanical control light source position conversion is designed, and it is necessary to ensure that each light source realizing different functions is located at a focus position when realizing the corresponding function, so that the aforementioned defects in the prior art can be essentially solved.

The mechanical module for realizing position conversion is connected with the light source, and after receiving a position conversion signal of the electronic control unit for controlling the mechanical module, the position of the light source is changed by changing the position of the mechanical module for realizing position conversion, so that the aim of the invention is fulfilled.

The position changing modes of the mechanical module for realizing the position changing include a motor movement mode, a rotation mode of a baffle plate or any part capable of realizing the rotation mode, a movement mode of a push rod or any rod part, a spring mode and the like, and the position changing modes are only examples and do not limit the protection scope, namely, the position changing modes of the movement mode, the rotation mode and the like are not limited, and the specific structure or the mode for realizing the position changing modes is not limited.

The mechanical module for realizing position conversion ensures that the position of a light source for realizing corresponding functions is accurately converted, after the conversion is realized, the mechanical module for realizing position conversion is kept still, the light source is ensured to be positioned at a position required by a certain optical system, meanwhile, the mechanical module for realizing position conversion synchronously waits for the input of a new signal of an electronic control unit for controlling the mechanical module, and when the new signal is input, the mechanical module for realizing position conversion can carry out the next position conversion, so that the realization of multiple functions is ensured.

The electronic control unit for controlling the mechanical module is an electronic control module of the mechanical module for realizing position conversion. The electronic control unit for controlling the mechanical module is used for analyzing a bus instruction, judging whether the position of the light source is accurate, and mainly controlling the mechanical module for realizing position conversion, including driving, keeping driving, and stopping, and further including diversification of driving modes, including forward driving, reverse driving, clockwise driving, counterclockwise driving, and the like.

Specifically, the method comprises the steps of identifying whether the position of the LED is matched with the signal requirement given by the bus when the bus gives the corresponding car lamp function signal, and giving a control command to enable the mechanical module to generate position conversion if the position of the LED is not matched with the signal requirement given by the bus. It is here to be mentioned that the electronic control unit of the control mechanism module may comprise a detector for identifying whether the position of the light source is correct.

In the process of position conversion of the mechanical module, the electronic control unit for controlling the mechanical module needs to update in real time and identify whether the position of the light source reaches an accurate position matched with a signal requirement given by the bus, if so, a control instruction is sent to stop the position change of the mechanical module, if not, the position conversion of the mechanical module is continued, the identification position is updated in real time, and if not, a control instruction is sent to stop the position change of the mechanical module.

The light source may be a conventional bulb, or a halogen or xenon bulb in a PES module, or various types of semiconductor light sources, or laser light sources of various light emitting principles, and other light sources capable of realizing lighting and light emitting according to design requirements, and most preferably, or currently, the most commonly used light source on the market is a semiconductor light emitting chip, and the semiconductor light emitting chip may be, but is not limited to, an LED (light emitting diode), an OLED, an AMOLED (active matrix organic LED), and the like, which certainly does not indicate that a new light source will not replace the trend in the future, or becomes a more preferred option.

The light source and the mechanical module for realizing position conversion are connected together.

Since the whole optical system is required to realize at least two or more functions, the number of the light sources is at least two, and is not limited to two, and the number of the light sources can be adjusted according to specific actual design. The plurality of light sources may be of different colors or the same color. And the specific models of the light sources are different, preferably of the same color.

For example, in the case of a plurality of light sources of different colors: the two light sources are respectively amber and white, wherein the amber realizes the function of a steering lamp, the white realizes the function of a daytime running lamp, and the white can realize the function of a position lamp of a front lamp through PWM control. In this case, the amber light source and the white light source in the same area can simultaneously realize three functions of steering, daytime running light and position light. The above is merely an example and does not limit the other possibilities of colors and color combinations.

A specific example of the same color may be that the two light sources are red, but the specific types are different, where one light source realizes the function of a tail lamp position light, and the other light source realizes the function of a tail lamp stop light. The light source under the electromechanical control unit is provided with a heat dissipation unit to help the light source dissipate heat and ensure optical performance. The specific heat dissipation unit conditions are determined according to the actual light source power and the designed thermal simulation risk conditions. Another situation is that there is no risk of light source heat, and a heat dissipating unit may not be provided.

The light source can also realize the function of a welcome lamp, and at the moment, the color of the light source is more diversified and various, the types and the number of the light source are more, and more possibilities are realized.

The in-process light source of light source position transform can be in the state of extinguishing or lighting according to actual design demand, and preferably, the light source is in the state of extinguishing in the light source position transform process, and after the light source position transform was ended, the electronic module that the control light source that will say in detail below lighted can supply power rapidly, lighted whole optical function implementation system, realizes corresponding function. Of course, the light source can be in a lighting state during the light source position changing process according to specific design requirements and conditions.

An electronic module that controls the illumination of the light source implements the control of the light source. The electronic control unit can control different lighting modes of the light source, such as the most basic lighting and extinguishing, or more complicated, such as sequential lighting or welcome function, for example, a yellow light source and a white light source are added in the same light source area to realize two functions of steering and daytime running lights, sequential lighting of the steering lights of the yellow light source can be realized through the electronic control unit, and the daytime running lights of the white light source can control current through the electronic control unit to change the lighting sequence, the lighting mode and the like.

A general electronic control unit (BUS) BUS, an electronic control unit for controlling the whole system, comprising an electronic control unit for controlling the mechanical module and an electronic control unit for controlling the light source lighting mode. The system can also be provided with no BUS of a total electronic control unit (BUS), only realizes simple mechanical transformation and on-off control of the light source, and is not suitable for complex dynamic lighting.

The optical function implementing system refers to an optical unit for implementing a corresponding function, and the optical unit may be an optical system of different form, for example, an optical system for implementing an optical function by a plurality of optical subunits through a matrix array, or a light guide, or an optical system applied to a reflection bowl, or a direct-projection optical system, or any other optical unit which is not mentioned here but is capable of implementing a corresponding function.

Taking the optical system which is optimally suitable for the invention and realizes the optical function by a plurality of optical subunits through a matrix array, the invention is further refined, and the electronic control module of the light source lighting mode of the electromechanical control unit can be integrated together or divided into two parts.

Preferably, when the number of the matrix arrays corresponding to the optical units for realizing the optical function is large, the light source and the electronic control module for the lighting mode of the light source may be two separate parts. Different from a conventional automobile light source control system, the light source and the electronic control module of the light source are integrated together, and in a separated system, the light source part can independently move and change the position without driving the electronic control module to change the position together, so that more flexibility is provided for the light source;

the further improvement is that when the number of the matrix arrays corresponding to the optical system for realizing the optical function is small, the light source and the electronic control module of the light source lighting mode can be divided into two parts or integrated into one part. The mechanical module for realizing position conversion drives the whole light source and the electronic control module for lighting the light source to realize position conversion together.

The further improvement lies in that the light source and the optical unit in the light source function realization system have a position relation required by an optical design, and preferably, the light source is located at a focal position of the optical unit, certainly not limited to the focal position, and may be other optical requirements or better optical positions, and a plurality of light sources may be changed in position, so that when different functions are realized, the corresponding light sources are all located at the design required positions of the optical unit, thereby achieving the purpose of the present invention.

The working principle is as follows: when the corresponding function needs to be realized according to the actual requirement or the instruction of the whole vehicle, the position of the light source needs to be moved to the required position of the optical function realization system, such as the focal position. When the system is to realize the corresponding function and the optimal optical effect is desired, only the mechanical module for realizing the position conversion is needed to rotate or move the light source for realizing the corresponding function or ensure that the position of the light source is converted to the required position of the optical function realization system, such as the focus position, by a certain position conversion of a certain mechanical structure.

When the system needs to change the position of the light source, the general electronic control unit sends a signal for changing the position of the light source to the electromechanical control unit, the electronic control unit for controlling the mechanical module in the electromechanical control unit receives the signal, and then the electronic control unit for controlling the mechanical module sends position change information to the mechanical module for realizing the position change. The mechanical module for realizing position conversion is mechanically operated and changes position, so that the position of the light source connected with the mechanical module is converted, after the position is converted to the position with appointed requirement, the light source lighting mode electronic control unit lights the corresponding light source to complete the work of the whole electromechanical control unit, and the lighted light source and the optical unit of the optical function realization system jointly realize the lighting work of the optical function required by the whole vehicle or the vehicle lamp at the moment. When there is a switching signal of the function of the vehicle lamp, that is, when the position of the light source needs to be changed, the general electronic control unit will send a signal of changing the position of the light source to the electromechanical control unit again, and the following operations as described above in the specific case are performed. The whole system can achieve the optical functions of completing the position conversion of the light source and realizing corresponding requirements.

The invention has the beneficial effects that: the light source position conversion is realized based on electromechanical control, the light source of the optical system for realizing multifunctional lighting is ensured to be always in a required position, such as a focus position, the efficiency lighting effect of the system is realized by the whole optical function, and the like, and the comprehensive consideration reaches the optimal state; the light source and the electronic module for controlling the lighting mode of the light source can be set to be separated or integrated into one part according to actual conditions, so that the flexibility of the system is ensured when the light source is displaced.
