Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a lamp capable of realizing multiple light-emitting angles and a mixed light adjustment method. Background Art

[0002] In the field of lighting, especially outdoor and commercial lighting, there are diverse demands for the beam angles of lamps. Traditional lamp designs usually only provide a single beam angle, which limits the applicability of lamps in different lighting scenarios. For example, a 60-degree beam may be required for street lighting, 90 degrees for flood lighting, and 110 degrees for lighting specific areas. In order to meet these different needs, it is usually necessary to design and produce lamps with multiple different angles, which increases production costs and the complexity of inventory management.

[0003] In addition, when adjusting the light-emitting angle of existing lamps, it is often necessary to physically rotate the optical lens or replace different lens components, which is not only inconvenient to operate, but also limits the range of adjustment angle. Therefore, the market is in urgent need of a lamp that can flexibly adjust the light-emitting angle to meet the changing lighting needs. Summary of the invention

[0004] The object of the present invention is to provide a lamp capable of realizing multiple light-emitting angles and a mixed light adjustment method, aiming to solve the problem that the existing lamps can usually only provide a single light-emitting angle.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a method for adjusting light mixing of a lamp capable of achieving multiple light-emitting angles, comprising the following steps: Design lighting fixtures; Set the lighting angle of the lamp; Simulate and calculate the luminous flux ratio of lamps based on the luminous angle; Control lamp adjustment based on luminous flux ratio.

[0006] Among them, in "Designing lamps", the following steps are included: Prepare the mounting plate, large-angle optical structure, small-angle optical structure and control module according to the design drawings; Welding and installing the mounting plate, the large-angle optical structure, the small-angle optical structure and the control module to obtain a semi-finished lamp; Conduct power-on testing on the semi-finished lamp to obtain the lamp.

[0007] Among them, in "Setting the lighting angle of the lamp", the following steps are included: Obtain user demand data; Extract based on user demand data to obtain the required luminous angle.

[0008] Among them, in "simulating and calculating the luminous flux ratio of lamps based on the luminous angle", the following steps are included: Simulate the designed large-angle optical structure and small-angle optical structure respectively to obtain the light effects at large and small angles, and record the corresponding LED luminous flux; According to the set light-emitting angle, the LED luminous flux ratio in the large-angle and small-angle optical structures is adjusted, and mixed light simulation is performed to obtain the LED luminous flux ratio at different light-emitting angles.

[0009] Among them, in "controlling lamp adjustment based on luminous flux ratio", the following steps are included: Input the desired lighting angle through the control panel; The control module calculates the LED luminous flux that needs to be adjusted based on the LED luminous flux ratio data at different luminous angles; The control module controls the light-emitting angle of the lamp based on the calculated LED luminous flux.

[0010] Among them, in “the control module controls the light-emitting angle of the lamp based on the calculated LED luminous flux”, the following steps are included: Send instructions to the LED drive circuit to adjust the luminous intensity of the LED; The LED driving circuit adjusts the luminous flux ratio of the LED according to the instruction.

[0011] In a second aspect, a lamp capable of realizing multiple light-emitting angles is used in the light mixing adjustment method for the lamp capable of realizing multiple light-emitting angles described in the first aspect. It comprises a mounting plate, a large-angle optical structure, a small-angle optical structure and a control module; the large-angle optical structure and the small-angle optical structure are respectively connected to the control module, and the large-angle optical structure, the small-angle optical structure and the control module are all mounted on the mounting plate.

[0012] The present invention discloses a method for adjusting the light mixing of a lamp with multiple light-emitting angles, comprising the following steps: designing a lamp; setting the light-emitting angle of the lamp; simulating and calculating the luminous flux ratio of the lamp based on the light-emitting angle; and controlling the adjustment of the lamp based on the luminous flux ratio. Compared with the traditional lamp with a single light-emitting angle, which may cause light waste or insufficient in certain scenes, the lamp with an adjustable light-emitting angle can more accurately match the lighting needs and reduce unnecessary energy consumption. In addition, by reducing the need to purchase additional lamps due to insufficient or excessive lighting, the cost expenditure of users can be reduced in the long run. By introducing an adjustable optical structure, a variable light source layout or advanced electronic control technology, the lamp can adjust the light-emitting angle according to actual needs. This flexibility enables the same lamp to be suitable for a variety of lighting scenarios, such as from indoor reading to outdoor gatherings, from narrow corridors to spacious living rooms, and the lighting effect can be optimized without replacing the lamp, solving the problem that existing lamps can usually only provide a single light-emitting angle.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] See also Figures 1 to 9 In a first aspect, the present invention provides a method for adjusting light mixing of a lamp capable of realizing multiple light-emitting angles, comprising the following steps: S1 design lamps; S11 prepares the installation plate 1, the large-angle optical structure 2, the small-angle optical structure 3 and the control module 4 according to the design drawing; Specifically, the required installation disk 1, large-angle optical structure 2, small-angle optical structure 3 and control module 4 are prepared according to the design drawings, and the large-angle optical structure 2, small-angle optical structure 3 and control module 4 are preliminarily assembled and tested to ensure that they can work normally.

[0027] S12 welds and installs the mounting plate 1, the large-angle optical structure 2, the small-angle optical structure 3 and the control module 4 to obtain a semi-finished lamp; Specifically, PCB board welding: soldering LED chips, electronic components, etc. to the circuit board to form LED drive circuits and control circuits, installing large-angle optical structures 2 and small-angle optical structures 3 on the mounting plate 1 to ensure that light can be distributed according to design requirements, and connecting the control module 4 to the LED drive circuit to ensure that it can receive user input and control the LED luminous intensity. Conduct preliminary quality inspections on semi-finished lamps to ensure that their structures are intact and free of damage.

[0028] S13 performs power-on detection on the semi-finished lamp to obtain the lamp.

[0029] Specifically, connect the semi-finished lamps to the power supply and test whether they can work normally, including luminous intensity, color temperature, color saturation, etc., verify whether the luminous angle adjustment function of the lamp is normal, including inputting different luminous angles through the control panel, observing the actual luminous effect of the lamp, and conducting final quality inspection on the lamp to ensure that it meets the design requirements and has good safety and stability.

[0030] S2 sets the lighting angle of the lamp; S21 obtains user demand data; Specifically, collect users' requirements on the luminous angle of lamps through questionnaire surveys, customer interviews, etc. Analyze the collected user requirements to determine the common luminous angle range and special requirements in specific application scenarios.

[0031] S22 extracts the required luminous angle based on the user demand data.

[0032] Specifically, record the user demand data (including the range of luminous angles, preferences, usage scenarios, etc.), organize and analyze the recorded data, extract useful information, and provide a basis for subsequent simulation calculations.

[0033] S3 simulates and calculates the luminous flux ratio of the lamp based on the luminous angle; S31 simulates the designed large-angle optical structure 2 and small-angle optical structure 3 respectively to obtain the light effects of the large angle and the small angle, and records the corresponding LED luminous flux; Specifically, the ray tracing function of the simulation software is started to simulate the propagation process of light in the large-angle optical structure 2 and the small-angle optical structure 3 after the light is emitted from the LED. Ray tracing calculates optical phenomena such as reflection, refraction and transmission of light on the surface of each optical element, thereby obtaining the distribution of light in the entire structure. The traced light is analyzed using the ray analysis function of the simulation software. Parameters such as the intensity, direction, and spectral distribution of the light can be calculated, and corresponding light effect diagrams can be generated. These effect diagrams can intuitively show the distribution and focusing of light in the structure. During the simulation process, the luminous flux of each LED is recorded. Luminous flux is a physical quantity that describes the luminous ability of a light source. It represents the light energy emitted by the light source per unit time. For each LED in the large-angle optical structure 2 and the small-angle optical structure 3, its luminous flux value needs to be recorded for subsequent analysis and calculation. In the simulation software, the luminous flux value of each LED can be directly measured. This is usually achieved by setting a luminous flux detector in the model, which receives and measures the light energy emitted by the LED. After the simulation is completed, the simulation results are verified and optimized. Compare the simulation results with the actual situation to check whether the light effect and LED luminous flux meet the expectations. If there are differences, analyze the reasons and make corresponding adjustments. According to the verification results, optimize the design of the optical structure. The light effect and the distribution of LED luminous flux can be improved by adjusting parameters such as the shape of the lens, the angle of the reflector, and the transmittance of the filter. The optimized design is simulated again to ensure that it meets the requirements.

[0034] S32 adjusts the LED luminous flux ratio in the large-angle and small-angle optical structures 3 according to the set luminous angle, performs mixed light simulation, and obtains the LED luminous flux ratio at different luminous angles.

[0035] Specifically, first, the luminous angle of the lamp needs to be set according to the actual application scenario and user needs. This angle can be fixed or adjustable. According to the set luminous angle, the ratio of the LED luminous flux in the large-angle and small-angle optical structures 3 needs to be adjusted. This is achieved by changing the driving current or voltage of the LED. By adjusting the luminous intensity of the LED, its luminous flux distribution in the optical structure can be changed, thereby affecting the luminous angle of the lamp. When adjusting the LED luminous flux ratio, keep the overall brightness and color temperature of the lamp stable. After adjusting the LED luminous flux ratio, perform mixed light simulation to verify the adjustment effect. In the mixed light simulation process, the complexity of the optical structure, the luminous characteristics of the LED, and the influence of environmental factors are considered. By continuously optimizing the simulation parameters and models, more accurate and reliable simulation results can be obtained. Finally, according to the results of the mixed light simulation, the luminous flux ratio of the LED at different luminous angles can be obtained. By comparing the luminous flux ratio of the LED at different luminous angles, the lighting effect and adaptability of the lamp can be evaluated.

[0036] S4 controls the dimming of lamps based on the ratio of luminous flux.

[0037] S41 inputs the desired lighting angle through the control panel; Specifically, the user inputs the desired light emitting angle value through the control panel, and the control module 4 verifies the input value to ensure that it is within a reasonable range.

[0038] S42: the control module 4 calculates the LED luminous flux that needs to be adjusted according to the luminous flux ratio data of the LEDs at different luminous angles; Specifically, the control module 4 retrieves the LED luminous flux ratio data at the corresponding light-emitting angle from the stored simulation results, and calculates the LED luminous flux ratio that needs to be adjusted based on the retrieved data.

[0039] S43: The control module 4 controls the light-emitting angle of the lamp based on the calculated LED luminous flux.

[0040] S431 sends a command to the LED driving circuit to adjust the luminous intensity of the LED; Specifically, the control module 4 generates an instruction format that meets the requirements of the LED driving circuit and sends the instruction to the LED driving circuit using a communication protocol (such as I2C, SPI, UART, etc.).

[0041] The S432LED driver circuit adjusts the luminous flux ratio of the LED according to the instructions.

[0042] Specifically, the LED driving circuit receives and decodes the instruction sent by the control module 4. According to the decoded instruction, the driving current of the LED is adjusted, thereby changing the luminous intensity of the LED and achieving the adjustment of the luminous angle.

[0043] Embodiment 1, 90 degree light angle lamp: When the luminous flux of each LED arranged in the large-angle optical structure 2 and the LED arranged in the small-angle optical structure 3 is 50% of the luminous flux of a single LED, mixed light is used.

[0044] Embodiment 2, 110 degree luminous angle lamp: When 90% of the luminous flux of each LED arranged in the large-angle optical structure 2 and 10% of the luminous flux of each LED arranged in the small-angle optical structure are mixed and used, the angle is 110 degrees.

[0045] Embodiment 3, 60 degree luminous angle lamp: When 10% of the luminous flux of each LED arranged in the large-angle optical structure 2 and 90% of the luminous flux of each LED arranged in the small-angle optical structure are mixed and used at an angle of 60 degrees.

[0046] Embodiment 4: When light from large and small light emitting angles is mixed, by changing the ratio of LED luminous flux within the large and small light emitting angles, changes in different angles of 30 degrees to 150 degrees can be achieved.

[0047] In this embodiment, the mounting plate 1 serves as the basic supporting component of the lamp, and the mounting plate 1 is responsible for fixing the lamp to the wall or ceiling. Large-angle optical structure 2: A series of free-form surface annular structures are designed, which can refract LED light into light at a large angle. By adjusting the parameters of these structures, different large-angle lighting effects can be achieved. Small-angle optical structure 3: A series of free-form surface annular structures are also designed, but these structures are used to refract LED light into light at a small angle. Combined with the large-angle optical structure 2, a richer lighting effect can be formed. The large-angle optical structure 2 and the small-angle optical structure 3 are installed on the mounting plate 1 in sequence, and the control module 4 is responsible for receiving user instructions and adjusting the luminous flux ratio of the LED according to the instructions, thereby achieving the adjustment of the light-emitting angle.
