DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] This embodiment provides a sky light environment simulation device, including:

[0034] A first light source module, used for emitting visible light and irradiating the visible light to a target area, wherein the first light source module includes at least two first light sources, any one of the first light sources is used for emitting visible light, and the color temperatures of emitted light of various first light sources are different;

[0035] A second light source module is used to emit non-visible light and irradiate the non-visible light to the target area;

[0036] The control module is connected to the first light source module and the second light source module respectively, and is used to control the light emitted by the first light source module and the second light source module respectively.

[0037] The first light source module emits visible light, and the second light source module emits non-visible light, so that the light environment formed by the sky light environment simulation device includes visible light and non-visible light. Among them, the first light source module includes at least two first light sources, any one of which is used to emit visible light, and the color temperature of the emitted light of various first light sources is different. The color temperature of the light environment formed by the sky light environment simulation device is adjustable through various first light sources. The light environment formed by the sky light environment simulation device of this embodiment includes visible light and non-visible light, which can not only meet the needs of the human eye and some camera systems, but also meet the application needs of some sensors working in the non-visible light band.

[0038] For example, reference may be made to FIG. 1, which is a schematic diagram of a sky light environment simulation device provided by an embodiment. As shown in the figure, the sky light environment simulation device includes a first light source module 101, a second light source module 102 and a control module 100. The control module 100 is connected to the first light source module 101 and the second light source module 102, respectively. The first light source module 101 emits visible light, and the second light source module 102 emits non-visible light to form a required light environment for the target area. The target area can be considered as an area that needs to be provided with a light environment by the sky light environment simulation device, such as a test room.

[0039] The wavelength of the emitted light of the first light source module 101 may be in the range of 380nm~780nm. In this embodiment, the wavelength band of the emitted light of the first light source module 101 is not specifically limited. The emitted light of the first light source module 101 may be a certain wavelength band in the range of 380nm~780nm, or may cover the entire wavelength band of 380nm~780nm. In practical applications, it may be set according to requirements.

[0040] In this embodiment, there is no limit on the number of first light sources included in the first light source module 101, and there is no limit on the wavelength band and color temperature of the emitted light of each first light source, which can be set according to needs in practical applications. In some embodiments, the control module 100 is used to control the intensity of the emitted light of various first light sources respectively, so that the color temperature and / or luminous flux of the emitted light of the first light source module 101 meet the requirements, so that the color temperature and / or luminous flux of the light environment formed by the sky light environment simulation device meet the requirements, and the color temperature and / or luminous flux of the light environment formed by the sky light environment simulation device are adjustable.

[0041] In some embodiments, the first light source module 101 may include a first first light source and a second first light source, the color temperature of the emitted light of the first first light source is less than or equal to 3000k, and the color temperature of the emitted light of the second first light source is greater than or equal to 6000k. By setting two first light sources with different color temperatures, the color temperature and / or luminous flux of the emitted light of the first light source module 101 can be adjusted by controlling the emitted light intensity of the first first light source and the emitted light intensity of the second first light source. Exemplarily in a specific example, the first light source module 101 includes a first first light source and a second first light source, the first first light source emits white light and is 2700k warm white light, and the second first light source emits white light and is 6500k cold white light.

[0042] The emitted light of the second light source module 102 may be infrared light or ultraviolet light, or the emitted light of the second light source module 102 may include infrared light and ultraviolet light. Reference may be made to FIG2 , which is a spectrum diagram of sunlight, wherein 380 nm to 780 nm is visible light, above 780 nm is infrared light, and below 380 nm is ultraviolet light. In this embodiment, the emitted light band of the second light source module 102 is not specifically limited, and the emitted light of the second light source module 102 may be a certain band above 780 nm or a certain band below 380 nm, and may be set as required in practical applications.

[0043] The sky light environment simulation device is a comprehensive natural light simulation system that simulates the sun, moon, clouds and blue sky reflections on the earth. It can simulate complex sky light environments including standard sunny days, standard cloudy days, sunrise, cloudy, thunderstorms, moonlight, water surface road reflections, etc. How to make the sky light environment simulation device simulate the solar spectrum more realistically is of great significance. So, from the spectrum point of view, it contains two parts: one is the visible light part, which requires the simulation device to simulate the sky light more accurately, so that the test object (usually a person) cannot perceive the difference between the light emitted by the simulation device and the real sky light in terms of color temperature, brightness, etc.; the other is the non-visible light part, such as infrared light (mainly) and ultraviolet light. Since the test objects of the sky light environment simulation device can also include various sensors on airplanes or cars, these sensors will also respond in the non-visible light band. For example, for applications such as autonomous driving, the laser emitted by the lidar is generally in the infrared band and will be affected by the infrared background in the sky light. If the sky light environment simulation device only has the light output of the visible light part, it will cause the lack of the non-visible light part of the environment, thereby affecting the accuracy of the system test. Then, the light environment formed by the sky light environment simulation device of this embodiment includes visible light and non-visible light, which simulates the sky light relatively more accurately. It can not only meet the subject's demand for visible light in the light environment, but also meet the application requirements of some sensors working in the non-visible light band.

[0044] In some embodiments, the second light source module 102 includes at least two second light sources, any one of which is used to emit non-visible light, and the center wavelengths of the emitted light of various second light sources are different. The center wavelength of the emitted light of any second light source may be greater than 780nm or may be less than 380nm. Exemplarily, the center wavelength of the emitted light of the second light source may be 850nm, 905nm or 1550nm, and these infrared emission spectrum bands are infrared spectrum bands often used by devices such as laser radar. In the sky light environment simulation device of this embodiment, the emission spectrum of the sky light environment simulation device is not deliberately made to completely match the solar spectrum, but only the spectral energy of several infrared emission spectrum bands is guaranteed to be consistent with the solar spectrum energy in the actual test scene. Since the sensing equipment such as laser radar usually filters the corresponding band at the receiving end for the laser band it emits, the sky light environment simulation device only uses a light source with a specific center wavelength in the infrared light, which can meet the test requirements while avoiding cost increase and energy waste. In some embodiments, the first light source module 101 includes a first first light source and a second first light source, the color temperature of the output light of the first first light source is less than or equal to 3000K, and the color temperature of the output light of the second first light source is greater than or equal to 6000K, and the second light source module 102 includes a first second light source, and the center wavelength of the output light of the first second light source is 850nm, 905nm or 1550nm.

[0045] In some embodiments, the control module 100 is used to control the intensity of the emitted light of each of the first light sources and the intensity of the emitted light of the second light source module 102, respectively, so that the spectrum of the emitted light of the sky light environment simulation device meets the requirements. By controlling the intensity of the emitted light of each of the first light sources and the intensity of the emitted light of the second light source module 102, the intensity ratio of each of the wavelength bands of light is adjusted, so that the spectrum of the light environment formed after the various wavelength bands of light are mixed meets the requirements. In the embodiment where the second light source module 102 includes at least two second light sources and the center wavelengths of the emitted light of each of the second light sources are different, the control module 100 can control the intensity of the emitted light of each of the first light sources and the intensity of the emitted light of each of the second light sources, respectively, and adjust the intensity ratio of each of the wavelength bands of light, so that the spectrum of the light environment formed after the various wavelength bands of light are mixed meets the requirements, so that the spectrum of the light environment formed by the sky light environment simulation device meets the requirements.

[0046] In some embodiments, the control module 100 can receive a control instruction issued by a user, and control the light emitted by the first light source module 101 and the light emitted by the second light source module 102 according to the control instruction. The control module 100 can communicate through Ethernet, WIFI, RS485 interface, Bluetooth, Zigbee, DMX512 signal transmission mode or DALI signal transmission mode, using these communication modes and control topologies.

[0047] For example, reference may be made to FIG3, which is a schematic diagram of a sky light environment simulation device provided by another embodiment. As shown in the figure, the sky light environment simulation device includes a control module 100, a first light source module 101, an infrared module 103, and an ultraviolet module 104. The control module 100 is connected to the first light source module 101, the infrared module 103, and the ultraviolet module 104, respectively. The first light source module 101 emits visible light, the infrared module 103 emits infrared light, and the ultraviolet module 104 emits ultraviolet light, so that the light environment formed by the sky light environment simulation device includes visible light, infrared light, and ultraviolet light. The control module 100 can receive control instructions issued by the user, and control the intensity of the emitted light of the infrared module 103, the ultraviolet module 104, and the first light source module 101 according to the control instructions, thereby changing the color temperature, luminous flux, and spectral output. The sky light environment simulation device utilizes a reasonable combination of three light source modules. According to the requirements of different test scenarios, the first light source module 101 (i.e., the visible light module) is used to control parameters such as color temperature and luminous flux. By adding a limited number of infrared modules corresponding to the sensor bands most likely to be used by cars / aircraft, the simulation capability of the device is enhanced to more realistically simulate various complex sky light environments including sunny days, cloudy days, sunrises, cloudy days, thunderstorms, moonlight, starlight, water surface road reflection, etc., without bringing too much cost / power consumption increase.

[0048] In some embodiments, the first light source module 101 may include a light emitting element, and the second light source module 102 may include a light emitting element. Each light emitting element may be arranged in an array, and different light emitting elements may be arranged in an array in a cross manner. Or different light emitting elements may be grouped and arranged in an array. Or each light emitting element may be packaged on a substrate in a chip-on-board (COB) manner. The intensity of the emitted light of the corresponding light source may be controlled by changing the current of the light emitting element. The light emitting element may be an LED.

[0049] In some embodiments, the sky light environment simulation device may further include: a light mixing module, which is arranged on the light emitting side of the first light source module 101 / the second light source module 102, and is used to make the emitted light of the first light source module 101 / the second light source module 102 pass through the light mixing module and then be emitted, so that the intensity distribution of the emitted light meets the requirements. In this embodiment, the structure of the light mixing module is not limited, and the light mixing module may include but is not limited to a diffuser plate, a reflective cup, an optical fiber, an optical lens, or a mixing cavity.

[0050] In some embodiments, the sky light environment simulation device may also include: a sensing module, connected to the control module 100, for obtaining the intensity / color temperature / spectrum of the output light of the sky light environment simulation device and transmitting the obtained intensity signal / color temperature signal / spectrum data to the control module 100; the control module 100 is used to compare the intensity / color temperature / spectrum of the output light of the sky light environment simulation device with the set intensity / color temperature / spectrum data, and control the output light of the first light source module 101 and the second light source module 102 respectively according to the deviation between the intensity / color temperature / spectrum of the output light of the sky light environment simulation device and the set intensity / color temperature / spectrum data.

[0051] The sensing module can be used to obtain the intensity of the emitted light of the sky light environment simulation device. The control module 100 compares the intensity of the emitted light of the sky light environment simulation device with the set intensity data, and controls the emitted light of the first light source module 101 and the second light source module 102 respectively according to the deviation between the two, so that the emitted light intensity of the sky light environment simulation device meets the requirements.

[0052] The sensing module can be used to obtain the color temperature of the output light of the sky light environment simulation device. The control module 100 compares the color temperature of the output light of the sky light environment simulation device with the set color temperature data, and controls the output light of the first light source module 101 and the second light source module 102 respectively according to the deviation between the two, so that the color temperature of the output light of the sky light environment simulation device meets the requirements.

[0053] The sensing module can be used to obtain the spectrum of the output light of the sky light environment simulation device. The control module 100 compares the spectral data of the output light of the sky light environment simulation device with the set spectral data, and controls the output light of the first light source module 101 and the second light source module 102 respectively according to the deviation between the two, so that the output light spectrum of the sky light environment simulation device meets the requirements.

[0054] The radiation energy setting values ​​of each spectrum band of various test scenes can be derived through actual measurement, such as the radiation energy setting values ​​of the infrared light band and / or the ultraviolet light band. As the test progresses, the output energy may be inconsistent with the set value due to problems such as light source attenuation. To address this problem, this sky light environment simulation device adds a sensor module to detect the actual intensity / color temperature / spectrum data and compare it with the set value to adjust the output energy.

[0055] In a specific example, the first light source module 101 includes a first first light source and a second first light source, the first first light source emits white light and is 2700K warm white light, and the second first light source emits white light and is 6500K cold white light. The center wavelength of the emitted light of the second light source module 102 is 905nm. For different test scenarios, the intensity of the emitted light of each light source can be controlled by the control module 100, so as to adjust the different spectral outputs of the device in the visible light / infrared light range. For the test for the human eye, only the 2700K warm white light source and the 6500K cold white light source can be adjusted to combine different color temperatures and luminous fluxes in the visible light range.

[0056] For sensor testing, the 905nm infrared light source can be adjusted to make its radiation energy match the solar radiation energy of the corresponding band in the actual space under the current test scenario. Different test scenarios here include time factors such as morning, noon, and dusk, and can also include location factors such as different longitudes and latitudes. Through the measured data under different combinations of factors, specific bands in different scenarios, such as the actual sky light energy data of 905nm, can be obtained, and this data can be used as the setting value of the 905nm band energy output of the simulation device.

[0057] In some embodiments, the sky light environment simulation device further includes a housing 110, the housing 110 is provided with a plurality of sequentially arranged mounting cavities 111, the mounting cavities 111 are used to mount the first light source module 101 or the second light source module 102, so that the first light source module 101 and the second light source module 102 are sequentially arranged.
