The first light-emitting element and the second light-emitting element together or individually emit output light to the outside.

[0008] The controller is electrically connected to the first light-emitting element and the second light-emitting element respectively, and the controller controls the brightness of the first light-emitting element and the second light-emitting element respectively to adjust the color temperature of the output light.

[0009] Optionally, the first light-emitting element is a cool white light-emitting element, and the brightness of the cool white light-emitting element is a first brightness; the second light-emitting element is a warm white light-emitting element, and the brightness of the warm white light-emitting element is a second brightness.

[0010] The controller controls the ratio of the first brightness to the second brightness to any value between 1.2 and 2, so as to emit the output light with a preset color temperature.

[0011] Optionally, the color temperature of the output light is any value between 2000K and 6000K.

[0012] Optionally, the output light includes a first output light and a second output light, wherein the color temperature of the first output light is any value between 2700K and 3300K, and the color temperature of the second output light is any value between 5700K and 6300K.

[0014] The first controller is electrically connected to the first light-emitting element, and the first controller controls the brightness of the first light-emitting element;

[0015] The second controller is electrically connected to the second light-emitting element, and the second controller controls the brightness of the second light-emitting element.

[0016] Optionally, the number of the first light-emitting elements includes multiple elements, the number of the second light-emitting elements includes multiple elements, and the first light-emitting elements and the second light-emitting elements are arranged alternately.

[0017] Optionally, a plurality of the first light-emitting elements and a plurality of the second light-emitting elements are staggered along the extension direction of the substrate.

[0018] Secondly, this application provides a lamp structure, which includes a housing and a lamp adjustment device disposed within the housing.

[0019] Thirdly, embodiments of this application propose a vehicle that includes the aforementioned lamp structure or the aforementioned lamp adjustment device.

[0020] Optionally, the vehicle further includes a light sensor electrically connected to a controller in the lighting adjustment device. The light sensor is used to detect ambient light intensity and transmit the detected ambient light intensity to the controller.

[0021] In this embodiment, the lamp adjustment device includes: a substrate, a first light-emitting element, a second light-emitting element, and a controller. The first and second light-emitting elements are respectively disposed on the substrate, and the color temperature of the light emitted by the first light-emitting element is any value between 5500K and 6500K, while the color temperature of the light emitted by the second light-emitting element is any value between 2250K and 3300K.

By controlling the brightness of the first and second light-emitting elements separately through the controller, the light emitted by the first and second light-emitting elements can be mixed so that the output light is biased towards the color characteristics, i.e., the color temperature, of the brighter light-emitting element, presenting either a cool or warm color temperature after mixing. Furthermore, the controller can also control the first or second light-emitting element to emit light independently, so that the output light presents either the cool color temperature of the first light-emitting element or the warm color temperature of the second light-emitting element. This allows users to adjust the color temperature of the output light to lean towards warm or cool colors according to their personal habits. Warm colors have strong penetrating power, are easy to observe, and give people a warm feeling, while cool colors have a more transparent appearance and a more technological feel. This allows the color temperature of the light fixture to be adjusted, enriching its display methods and improving the user experience.

[0032] Reference Figure 1 The diagram shows a schematic representation of a lamp adjustment device according to an embodiment of this application. Figure 2 The diagram illustrates the color temperature adjustment of a lighting device. Specifically, the lighting device may include: a substrate 10, a first light-emitting element 20, a second light-emitting element 30, and a controller 40. The first light-emitting element 20 and the second light-emitting element 30 are respectively disposed on the substrate 10. The color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, and the color temperature of the light emitted by the second light-emitting element is any value between 2250K and 3300K. The first light-emitting element 20 and the second light-emitting element 30 together or individually emit output light to the outside. The controller 40 is electrically connected to the first light-emitting element 20 and the second light-emitting element 30 respectively, and the controller 40 controls the brightness of the first light-emitting element and the second light-emitting element 30 to adjust the color temperature of the output light.

[0033] In this embodiment, the light emitted by the first light-emitting element 20 and the second light-emitting element 30 has different color temperatures; that is, the color characteristics of the light emitted by the first light-emitting element 20 are different from the color characteristics of the light emitted by the second light-emitting element 30. The color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, meaning the light emitted by the first light-emitting element 20 is biased towards a cool color temperature. The color temperature of the light emitted by the second light-emitting element 30 is any value between 2250K and 3300K, meaning the light emitted by the second light-emitting element 30 is biased towards a warm color temperature. By controlling the brightness of the first light-emitting element 20 and the second light-emitting element 30 respectively through the controller 40, the output light after mixing of the light emitted by the first light-emitting element 20 and the second light-emitting element 30 can be biased towards the color characteristics, i.e., color temperature, of the brighter light-emitting element, presenting a mixed cool or warm color temperature. Furthermore, the controller 40 can also control the first light-emitting element 20 or the second light-emitting element 30 to emit light independently, so that the output light presents the cool color temperature of the first light-emitting element 20 or the warm color temperature of the second light-emitting element 30. This allows users to adjust the color temperature of the output light to lean towards either a warm or cool color temperature according to their personal preferences. Warm color temperatures have stronger penetrating power, are easier to observe, and give a feeling of warmth, while cool color temperatures have a more transparent appearance and a more technological feel, etc. This allows the color temperature of the lamp structure to be adjusted, enriching its display methods and improving the user experience.

[0034] Specifically, in this embodiment, the color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, including the extreme values ​​of 5500K and 6500K, and any value between 5500K and 6500K. For example, the color temperature of the light emitted by the first light-emitting element 20 can be 5500K, 5800K, 6000K, 6300K, or 6500K, etc., and can be set according to actual needs. This embodiment does not limit the specific value of the color temperature of the light emitted by the first light-emitting element 20. Similarly, the color temperature of the light emitted by the second light-emitting element 30 is any value between 2250K and 3300K, including the extreme values ​​of 2250K and 3300K, and any value between 2250K and 3300K. For example, the color temperature of the light emitted by the second light-emitting element 30 can be 2250K, 2300K, 2550K, 3000K or 3300K, etc., and can be set according to actual needs. In this embodiment of the application, the specific value of the color temperature of the light emitted by the second light-emitting element 30 is not limited.

[0035] For example, in this embodiment, the first light-emitting element 20 can be set to a bluish light-emitting element, emitting cool color temperature light, and the second light-emitting element 30 can be set to a yellowish light-emitting element, emitting warm color temperature light. If the user wants to display a cool color temperature lighting effect, the controller 40 can control the brightness of the first light-emitting element 20 to be greater than the brightness of the second light-emitting element 30, so that after the light emitted by the first light-emitting element 20 and the second light-emitting element 30 is mixed, the output light is biased towards the color characteristics of the first light-emitting element 20, i.e., the cool color temperature. If the user wants to display a warm color temperature lighting effect, the controller 40 can control the brightness of the second light-emitting element 30 to be greater than the brightness of the first light-emitting element 20, so that after the light emitted by the first light-emitting element 20 and the second light-emitting element 30 is mixed, the output light is biased towards the color characteristics of the second light-emitting element 30, i.e., the warm color temperature.

[0036] In this embodiment, simultaneously illuminating the first light-emitting element 20 and the second light-emitting element 30 on the substrate 10 results in the mixing of colored light, producing output light of a new color. For example, the output light produced by mixing bluish and yellowish light is close to the effect of white light, and the color temperature of this white light is affected by the ratio of the brightness of the bluish and yellowish light. Therefore, the color temperature of the output light after mixing can be adjusted by controlling the brightness of the first light-emitting element 20 and the second light-emitting element 30.

[0037] Specifically, in the embodiments of this application, color temperature represents the color characteristics of light, and its unit can be expressed in Kelvin (K). The lower the color temperature value, the warmer the light color and the more yellow the light color; the higher the color temperature value, the cooler the light color and the more blue the light color. Brightness represents the intensity of light, and its unit can be expressed in nits (NIT). The lower the brightness value, the weaker the light color; the higher the brightness value, the stronger the light color.

[0038] For example, in this embodiment, the substrate 10 provides a mounting position for the first light-emitting element 20 and the second light-emitting element 30. The substrate 10 can be a PCB (Printed Circuit Board), also known as a rigid board, which gives the substrate 10 good structural strength and provides a more reliable connection for the first light-emitting element 20 and the second light-emitting element 30. Furthermore, connection circuits can be set on the PCB, facilitating the electrical connection between the controller 40 and the first light-emitting element 20 and the second light-emitting element 30 via the PCB. The structure is simple and the operation is convenient. The controller 40 can be electrically connected to the vehicle infotainment controller, and the vehicle infotainment controller can control the controller 40.

[0039] In this embodiment, for example, the first light-emitting element 20 and the second light-emitting element 30 can be LEDs (Light Emitting Diodes), which have good light-emitting effects, simple structures, and wide applications. Alternatively, the first light-emitting element 20 and the second light-emitting element 30 can also be OLEDs (Organic Light Emitting Diodes), or MicroLEDs (Micro Light Emitting Diodes), etc. This embodiment does not limit the specific type of the first light-emitting element 20 and the second light-emitting element 30.

[0040] Optionally, in this embodiment, the first light-emitting element 20 is a cool white light-emitting element with a first brightness, and the second light-emitting element 30 is a warm white light-emitting element with a second brightness; the ratio of the first brightness to the second brightness is any value between 1.2 and 2, to emit output light with a preset color temperature. Specifically, the first light-emitting element 20 is a cool white light-emitting element, that is, the first light-emitting element 20 is a bluish light-emitting element, and the second light-emitting element 30 is a warm white light-emitting element, that is, the second light-emitting element 30 is a yellowish light-emitting element. Setting the ratio of the first brightness to the second brightness to 1.2-2, that is, the ratio of the brightness of the bluish light-emitting element to the brightness of the yellowish light-emitting element to 1.2-2, can obtain output light with a preset color temperature that meets the requirements of the relevant lighting regulations GB-4758.

[0041] In this embodiment, the ratio of the first brightness to the second brightness is any value between 1.2 and 2, including the extreme values ​​of 1.2 and 2, and any value between 1.2 and 2. For example, the ratio of the first brightness to the second brightness can be 1.2, 1.5, 1.8, or 2, etc., and can be adjusted according to actual needs. This embodiment does not limit the specific value of the ratio of the first brightness to the second brightness.

[0042] In this embodiment of the application, since the brightness of the light-emitting element is proportional to the current output by the controller 40 to the light-emitting element, the ratio of the first brightness to the second brightness can also be derived as any value of 1.2-2 based on any value of 1.2-2.

[0043] Optionally, in this embodiment, the preset color temperature is any value between 2000K and 6000K to meet the requirements of the relevant lighting regulations GB-4758, so that the light emitted by the lighting fixture structure has good visibility. For example, the preset color temperature can be 2000K, 3000K, 4000K, 5000K, or 6000K, etc., and the specific value of the preset color temperature is not limited in this embodiment.

[0044] For example, such as Figure 2 The image shown is from CIE (Commission Internationale de l' The International Commission on Illumination (ICI) chromaticity diagram is used to verify whether the output light meets the relevant regulatory requirements. Through simulation experiments, the brightness of the first light-emitting element 20 and the second light-emitting element 30 can be controlled by the first controller 41 and the second controller 42 respectively. The detection data of the mixed output light is located within the black frame in the diagram and is displayed as the color temperature of any point on the red baseline.

[0045] In the embodiments of this application, for example, such as Figure 2 As shown, the controller 40 controls the brightness of the first light-emitting element 20 and the second light-emitting element 30 respectively, obtaining the chromaticity coordinates Cx and Cy of the mixed output light in the CIE chromaticity diagram as any value between 0.32 and 0.48. Cx represents the relative contribution of color in the red direction, a normalized value ranging from 0 to 1. The closer Cx is to 1, the more red the color leans; the closer Cx is to 0, the more blue the color leans. Cy represents the relative contribution of color in the green direction, also a normalized value ranging from 0 to 1. The closer Cy is to 1, the more green the color leans; the closer Cy is to 0, the more blue the color leans.

[0046] Specifically, in the embodiments of this application, Cx is any value from 0.32 to 0.48, including the extreme values ​​of 0.32 and 0.48, as well as any value between 0.32 and 0.48, such as 0.32, 0.35, 0.4, or 0.48, etc.; Cy is any value from 0.34 to 0.425, including the extreme values ​​of 0.34 and 0.425, as well as any value between 0.34 and 0.425, such as 0.34, 0.35, 0.4, or 0.425, etc.

[0047] Optionally, in this embodiment, the output light includes a first output light and a second output light. The color temperature of the first output light is any value between 2700K and 3300K, meaning the first output light has a warm color temperature. This allows the light emitted by the lamp structure to have strong penetrating power, making it easy to observe and giving a warm feeling, resulting in a better visual effect, especially in low ambient light conditions. The color temperature of the second output light is any value between 5700K and 6300K, meaning the second output light has a cool color temperature. This allows the lamp device to have a more transparent appearance and a technological feel, especially in high ambient light conditions.

[0048] In this embodiment, the color temperature of the first output light is any value between 2700K and 3300K, including the values ​​of 2700K and 3300K, or any value within the range of 2700K-3300K. For example, the color temperature of the first output light can be 2700K, 3000K, or 3300K, etc. This embodiment does not limit the specific value of the color temperature of the first output light and can set it according to actual needs. Similarly, the color temperature of the second output light is any value between 5700K and 6300K, including the values ​​of 5700K and 6300K, or any value within the range of 5700K-6300K. For example, the color temperature of the second output light can be 5700K, 6000K, or 6300K, etc., and can be set according to actual needs. This embodiment also does not limit the specific value of the color temperature of the second output light.

[0049] Optionally, in this embodiment, the controller 40 includes a first controller 41 and a second controller 42, which can be respectively disposed on the substrate 10. The first controller 41 is electrically connected to the first light-emitting element 20 and outputs a first current to the first light-emitting element 20 to control the brightness of the first light-emitting element 20. The second controller 42 is electrically connected to the second light-emitting element 30 and outputs a second current to the second light-emitting element 30 to control the brightness of the second light-emitting element 30. In this way, the first current is output to the first light-emitting element 20 through the electrical signal sent by the first controller 41, so that the first light-emitting element 20 operates under the first current. The larger the first current, the greater the brightness of the first light-emitting element 20, and the smaller the first current, the smaller the brightness of the first light-emitting element 20. Similarly, the electrical signal sent by the second controller 42 outputs a second current to the second light-emitting element 30, so that the second light-emitting element 30 works under the second current. The larger the second current, the brighter the second light-emitting element 30 is, and the smaller the second current, the smaller the brightness of the second light-emitting element 30 is. Thus, the brightness of the first light-emitting element 20 and the second light-emitting element 30 can be controlled by the output current of the first controller 41 and the second controller 42 respectively.

[0050] For example, in this embodiment, the first controller 41 and the second controller 42 can be MCUs (Microcontroller Units), which are small in size, easy to install, and have good control performance, and are widely used. Alternatively, other integrated circuits can be used to control the first light-emitting element 20 and the second light-emitting element 30, etc., and this embodiment does not limit the scope of these applications.

[0051] Optionally, in this embodiment, the number of first light-emitting elements 20 includes multiple elements, which can be spaced apart on the substrate 10. Similarly, the number of second light-emitting elements 30 includes multiple elements, which can also be spaced apart on the substrate 10. The first light-emitting elements 20 and second light-emitting elements 30 are arranged alternately. This allows the light-emitting positions of the lamp structure to be set using multiple spaced-apart first light-emitting elements 20 and second light-emitting elements 30. For example, the multiple first light-emitting elements 20 and multiple second light-emitting elements 30 can be arranged in a ring to create a ring-shaped light display effect. Furthermore, the alternating arrangement of the first light-emitting elements 20 and multiple second light-emitting elements 30 results in a more uniform color mixing effect for the light emitted by the multiple first light-emitting elements 20 and multiple second light-emitting elements 30.

[0052] In this embodiment, optionally, a plurality of first light-emitting elements 20 and a plurality of second light-emitting elements 30 are staggered along the extension direction of the substrate 10. Thus, along the extension direction of the substrate 10, i.e., its length direction, the first light-emitting elements 20 and the second light-emitting elements 30 are staggered, meaning that each first light-emitting element 20 is adjacent to a second light-emitting element 30. This results in a more uniform mixing effect of the light emitted by the first light-emitting elements 20 and the second light-emitting elements 30, further improving the uniformity and consistency of the mixed output light.

[0053] In some alternative embodiments of this application, a first light-emitting element 20 and a second light-emitting element 30 may be arranged alternately along the direction perpendicular to the extension direction of the substrate 10, i.e., its width direction. Multiple first light-emitting elements 20 are arranged alternately along the length direction of the substrate 10, and multiple second light-emitting elements 30 are also arranged alternately along the length direction of the substrate 10, thereby providing multiple rows of first light-emitting elements 20 and second light-emitting elements 30. This also enables the mixed output light to have better uniformity and consistency.

[0054] In summary, the lighting adjustment device of this application embodiment may include at least the following advantages:

[0055] In this embodiment, the lighting adjustment device includes: a substrate 10, a first light-emitting element 20, a second light-emitting element 30, and a controller 40. The first light-emitting element 20 and the second light-emitting element 30 are respectively disposed on the substrate 10. The color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, and the color temperature of the light emitted by the second light-emitting element 30 is any value between 2250K and 3300K. The first light-emitting element 20 and the second light-emitting element 30 together or individually emit output light to the outside. The controller 40 is electrically connected to the first light-emitting element 20 and the second light-emitting element 30 respectively, and the controller 40 controls the brightness of the first light-emitting element 20 and the second light-emitting element 30 to adjust the color temperature of the output light. In this embodiment, the color temperatures of the light emitted by the first light-emitting element 20 and the second light-emitting element 30 are different, that is, the color characteristics of the light emitted by the first light-emitting element 20 are different from the color characteristics of the light emitted by the second light-emitting element 30. The first light-emitting element 20 emits light with a color temperature of any value between 5500K and 6500K, meaning the light emitted by the first light-emitting element 20 leans towards a cool color temperature. The second light-emitting element 30 emits light with a color temperature of any value between 2250K and 3300K, meaning the light emitted by the second light-emitting element 30 leans towards a warm color temperature. By controlling the brightness of the first light-emitting element 20 and the second light-emitting element 30 respectively through the controller 40, the light emitted by the first light-emitting element 20 and the second light-emitting element 30 can be mixed so that the output light is biased towards the color characteristics, i.e., the color temperature, of the brighter light-emitting element, presenting a mixed cool color temperature or a warm color temperature. In addition, the controller 40 can also control the first light-emitting element 20 or the second light-emitting element 30 to emit light independently, so that the output light presents the cool color temperature of the first light-emitting element 20 or the warm color temperature of the second light-emitting element 30. This allows users to adjust the color temperature of the output light to lean towards warm or cool colors according to their personal habits. Warm colors have strong penetrating power, are easy to observe, and give people a warm feeling, while cool colors have a more transparent appearance and a more technological feel. This allows the color temperature of the light fixture to be adjusted, enriching its display methods and improving the user experience.

[0056] Reference Figure 3 The diagram shows a schematic of a lamp structure according to an embodiment of the present application. The lamp structure includes a housing 50 and a lamp adjustment device. The lamp adjustment device is disposed inside the housing 50, and the housing 50 protects the lamp adjustment structure.

[0057] For example, in this embodiment of the application, the lamp structure may further include a faceplate 51 and a freeform surface reflector 52. The faceplate 51 is connected to the housing 50 and can be connected to the vehicle body. The freeform surface reflector 52 is disposed inside the housing 50 and is mounted on the substrate 10. When the first light-emitting element 20 and the second light-emitting element 30 emit light respectively, the light can be reflected and mixed multiple times through the faceplate 51 and the freeform surface reflector 52 to achieve a better color mixing effect.

[0058] The lamp structure of the embodiments of this application can include at least the following advantages:

[0059] In this embodiment, the lamp structure includes a housing 50 and a lamp adjustment device. The lamp adjustment device is disposed within the housing 50 and includes a substrate 10, a first light-emitting element 20, a second light-emitting element 30, and a controller 40. The first light-emitting element 20 and the second light-emitting element 30 are respectively disposed on the substrate 10. The color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, and the color temperature of the light emitted by the second light-emitting element 30 is any value between 2250K and 3300K. The first light-emitting element 20 and the second light-emitting element 30 emit output light to the outside, either together or individually. The controller 40 is electrically connected to the first light-emitting element 20 and the second light-emitting element 30, and controls the brightness of the first light-emitting element 20 and the second light-emitting element 30 respectively to adjust the color temperature of the output light. In this embodiment, the color temperatures of the light emitted by the first light-emitting element 20 and the second light-emitting element 30 are different; that is, the color characteristics of the light emitted by the first light-emitting element 20 are different from the color characteristics of the light emitted by the second light-emitting element 30. The first light-emitting element 20 emits light with a color temperature of any value between 5500K and 6500K, meaning the light emitted by the first light-emitting element 20 leans towards a cool color temperature. The second light-emitting element 30 emits light with a color temperature of any value between 2250K and 3300K, meaning the light emitted by the second light-emitting element 30 leans towards a warm color temperature. By controlling the brightness of the first light-emitting element 20 and the second light-emitting element 30 respectively through the controller 40, the light emitted by the first light-emitting element 20 and the second light-emitting element 30 can be mixed so that the output light is biased towards the color characteristics, i.e., the color temperature, of the brighter light-emitting element, presenting a mixed cool color temperature or a warm color temperature. In addition, the controller 40 can also control the first light-emitting element 20 or the second light-emitting element 30 to emit light independently, so that the output light presents the cool color temperature of the first light-emitting element 20 or the warm color temperature of the second light-emitting element 30. This allows users to adjust the color temperature of the output light to lean towards warm or cool colors according to their personal habits. Warm colors have strong penetrating power, are easy to observe, and give people a warm feeling, while cool colors have a more transparent appearance and a more technological feel. This allows the color temperature of the light fixture to be adjusted, enriching its display methods and improving the user experience.

[0060] This application also provides a vehicle, which includes a lamp structure or a lamp adjustment device.

[0061] For example, in the embodiments of this application, the vehicle may include a small car, a medium-sized car, a sedan, a truck, a trailer, a CDV (Car Derived Van), an MPV (multi-Purpose Vehicle), an SUV (Sport Utility Vehicle), etc. The specific type of vehicle is not limited in the embodiments of this application.

[0062] Optionally, in this embodiment, the vehicle further includes a light sensor electrically connected to the controller 40 in the lighting adjustment device. The light sensor detects ambient illuminance and transmits the detected ambient illuminance to the controller 40. When the light sensor detects that the ambient illuminance is less than or equal to a preset value, the lighting adjustment device emits a first output light; when the light sensor detects that the ambient illuminance is greater than the preset value, the lighting adjustment device emits a second output light. In this way, the lighting adjustment device can be controlled to emit different lights adapted to the current environment according to changes in the external ambient light, enhancing the intelligence and technological feel of the vehicle's lighting structure.

[0063] For example, when the light sensor detects that the ambient light intensity is less than or equal to a preset value, it indicates that the vehicle is in a relatively dim environment. The lamp adjustment device can then emit a warmer first output light with a warm color temperature, giving the light emitted by the lamp structure strong penetrating power, making it easy to observe, giving a warm feeling, and providing a good visual effect. When the light sensor detects that the ambient light intensity is greater than the preset value, it indicates that the vehicle is in a relatively bright environment. The lamp adjustment device can then emit a cooler color temperature second output light, giving the light emitted by the lamp structure a more transparent and technologically advanced appearance.

[0064] Specifically, in this embodiment, illuminance is the luminous flux received per unit area, and its unit is lx (lux). For example, the preset value can be 5 lx, 8 lx, or 10 lx, etc. This embodiment does not limit the specific value of the preset value and can be adjusted according to actual needs.

[0065] In summary, the vehicle of this application embodiment may include at least the following advantages:

[0066] In this embodiment, the vehicle includes a lamp structure or a lamp adjustment device. The lamp structure includes a housing 50 and a lamp adjustment device, which is disposed within the housing 50. The lamp adjustment device includes a substrate 10, a first light-emitting element 20, a second light-emitting element 30, and a controller 40. The first light-emitting element 20 and the second light-emitting element 30 are respectively disposed on the substrate 10. The color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, and the color temperature of the light emitted by the second light-emitting element 30 is any value between 2250K and 3300K. The first light-emitting element 20 and the second light-emitting element 30 together or separately emit output light to the outside. The controller 40 is electrically connected to the first light-emitting element 20 and the second light-emitting element 30 respectively. The controller 40 controls the brightness of the first light-emitting element and the second light-emitting element 30 respectively to adjust the color temperature of the output light. In this embodiment, the light emitted by the first light-emitting element 20 and the second light-emitting element 30 has different color temperatures; that is, the color characteristics of the light emitted by the first light-emitting element 20 are different from the color characteristics of the light emitted by the second light-emitting element 30. The color temperature of the light emitted by the first light-emitting element 20 is any value between 5500K and 6500K, meaning the light emitted by the first light-emitting element 20 is biased towards a cool color temperature. The color temperature of the light emitted by the second light-emitting element 30 is any value between 2250K and 3300K, meaning the light emitted by the second light-emitting element 30 is biased towards a warm color temperature. By controlling the brightness of the first light-emitting element 20 and the second light-emitting element 30 respectively through the controller 40, the output light after mixing of the light emitted by the first light-emitting element 20 and the second light-emitting element 30 can be biased towards the color characteristics, i.e., color temperature, of the brighter light-emitting element, presenting a mixed cool or warm color temperature. Furthermore, the controller 40 can also control the first light-emitting element 20 or the second light-emitting element 30 to emit light independently, so that the output light presents the cool color temperature of the first light-emitting element 20 or the warm color temperature of the second light-emitting element 30. This allows users to adjust the color temperature of the output light to lean towards either a warm or cool color temperature according to their personal preferences. Warm color temperatures have stronger penetrating power, are easier to observe, and give a feeling of warmth, while cool color temperatures have a more transparent appearance and a more technological feel, etc. This allows the color temperature of the lamp structure to be adjusted, enriching its display methods and improving the user experience.
