Description

Technical Field

[0001] This invention relates to the field of LED lighting technology, and in particular to an electronically controlled LED lamp with adjustable angle, color temperature, and power, and its control method. Background Technology

[0002] Existing adjustable angle and color temperature LED lighting fixtures have many inherent defects in engineering applications. First, most adjustable lighting fixtures on the market use two independent drive control circuits to achieve angle switching and color temperature adjustment respectively. The circuit structure is redundant and complex, with a large number of components, resulting in high manufacturing costs. Moreover, the two sets of control signals are very prone to crosstalk, causing the lighting fixture to malfunction in dimming and color adjustment, and resulting in poor operational stability.

[0003] Secondly, traditional adjustable lamps often use LED beads arranged in a centralized zone, and the lenses they are paired with are mostly single, integrated light distribution structures. They cannot form a one-to-one independent light distribution relationship with the light panel zones. When switching light patterns and color temperatures, problems such as uneven light spots, local color shifts, and low light output efficiency are likely to occur, resulting in poor lighting consistency.

[0004] Meanwhile, traditional electronically controlled angle-adjusting and color-adjusting lamps generally use a 1:1 alternating lighting logic for LED beads, with an LED bead utilization rate of only 50% or less in any working state, resulting in serious waste of light source and low overall luminous efficiency; while mechanically controlled angle-adjusting lamps require lens replacement or mechanical displacement adjustment, which are cumbersome to operate, prone to seal damage, water and dust ingress, and have a high failure rate. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides an LED lamp with electronically controlled angle, color temperature and power adjustment and its control method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, an electronically controlled LED lamp with adjustable angle, color temperature, and power includes a bracket for mounting the lamp, a heat sink housing, an LED lamp board, a lens, a driver power supply, and a control module. The driver power supply is located on the back of the heat sink housing and is used to supply power to the LED lamp board. The heat sink housing is used to mount the LED lamp board. The lens covers the LED lamp board. The LED lamp board has multiple independent control areas. Each control area includes at least a constantly lit area, a first light pattern area, and a second light pattern area. Each control area is provided with LED beads arranged in a circular array. The LED beads in the constantly lit area remain lit in all operating modes.

[0008] The lens integrates at least two light distribution structures, which are configured one-to-one with the constant light area, the first light pattern area, and the second light pattern area, and are used to distribute the light emitted from the control area.

[0009] The control module includes an MCU controller and a DIP switch module. The MCU controller is used to read the position status of the DIP switch module and selectively turn on the first light pattern area and / or the second light pattern area of ​​the LED beads to achieve switching between different light emission angles and different color temperatures.

[0010] Furthermore, the control module also includes a PWM dimming circuit and a MOS driving circuit. The PWM dimming circuit is electrically connected to the PWM output port of the MCU controller. The signal input terminal of the MOS driving circuit is connected to the output terminal of the PWM dimming circuit in a one-to-one correspondence. The output terminal of the MOS driving circuit is independently electrically connected to the power supply circuits of the constant-on area, the first light pattern area, and the second light pattern area of ​​the LED light board, respectively.

[0011] Furthermore, the MCU controller outputs a PWM signal with a corresponding duty cycle to the PWM dimming circuit according to the current gear state of the DIP switch module. After being amplified by the MOS drive circuit, the power supply circuit of the corresponding control area is turned on to synchronously match the output power of each working gear.

[0012] Furthermore, the LED bead is a dual-color temperature LED bead, and the color temperature range of the dual-color temperature LED bead is between 2200K and 6500K.

[0013] Furthermore, the LED beads are arranged alternately in the constant-light area, the first light pattern area and the second light pattern area of ​​the LED light board, and the ratio of the number of LED beads in each control area is 1:1:1.

[0014] Furthermore, the light distribution structure inside the lens includes at least two of the following: symmetrical light type, polarized light type, Type III light type, and Type V light type, and the emission angle range of all light distribution structures is 15° to 90°.

[0015] Furthermore, the DIP switch module includes an angle DIP switch and a color temperature DIP switch, each with three switching positions. The MCU controller independently controls the switching of the emission angle and color temperature according to the position status.

[0016] Furthermore, the three switching modes of the angle DIP switch are as follows: First mode, the normally bright area and the first light pattern area are connected, and the second light pattern area is disconnected, forming a first light emission angle of 15° to 30°; Second mode, the normally bright area and the second light pattern area are connected, and the first light pattern area is disconnected, forming a second light emission angle of 60° to 90°; Third mode, all three control areas are connected simultaneously, forming a third light emission angle of 30° to 60°.

[0017] Furthermore, the three switching modes of the color temperature DIP switch are as follows: the first mode connects the normally bright area and the first light pattern area, outputting a first color temperature of 2200K to 3000K; the second mode connects the normally bright area and the second light pattern area, outputting a second color temperature of 5000K to 6500K; and the third mode simultaneously connects the three control areas, outputting a mixed color temperature of 3500K to 4500K.

[0018] Secondly, a control method for an electronically controlled LED lamp with adjustable angle, color temperature, and power is also provided, comprising the following steps:

[0019] S1, Power-on initialization: After the MCU controller is powered on, it completes initialization and reads the current gear status of the DIP switch module;

[0020] S2, Mode Determination and Execution: The MCU controller executes the corresponding control logic according to the read gear status, selectively turning on the power supply circuit of the LED beads in the first light pattern area and / or the second light pattern area to achieve switching of different light emission angles and different color temperatures; at the same time, the MCU controller outputs a PWM signal according to the PWM duty cycle corresponding to the current gear status, which is amplified by the MOS drive circuit and then turns on the corresponding control area to synchronously match the output power of each gear.

[0021] S3, Status Monitoring: If a change in the position of the DIP switch module is detected while the LED lamp is maintaining its current mode operation, the process returns to step S1 and is executed again to complete the switching between different light emission angles and different color temperatures.

[0022] The present invention provides an electronically controlled LED lamp with adjustable angle, color temperature, and power, and its control method thereof, which has the following advantages:

[0023] This invention employs a multi-independent control area and a constant-light zone lighting architecture, stably increasing the utilization rate of LED chips to 60%–100%, significantly improving the overall luminous efficacy of the luminaire, and reducing light source waste. It utilizes an integrated multi-beam composite lens and multiple independent control areas of the LED light panel for independent light distribution, eliminating the need for mechanical movement or lens replacement. Pure electronic control enables switching between narrow-angle, medium-angle, and wide-angle beams, eliminating the risk of water ingress during mechanical adjustment and ensuring high structural reliability. A single control circuit achieves independent adjustment of angle and color temperature, as well as adaptive output power at each level, abandoning the traditional dual-circuit redundancy structure, preventing signal crosstalk, simplifying the circuit, and reducing production costs. Hardware DIP switches independently control angle and color temperature, resisting electromagnetic interference, requiring no network, and eliminating the need for tool-based debugging, making it suitable for complex engineering scenarios such as industrial, outdoor, and sports fields. A single luminaire can achieve free combination of multiple angles, color temperatures, and power levels, thereby reducing product SKU types, lowering production and inventory costs, and improving scenario versatility.

[0035] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0036] like Figures 1-10As shown, this invention provides an electronically controlled LED lamp with adjustable angle, color temperature, and power. Specifically, it includes a bracket 6 for mounting the lamp, a heat sink housing 1, an LED light panel 2, a lens 3, a driver power supply 4, and a control module 5. The heat sink housing 1 is made of extruded aluminum alloy and is movably connected to the bracket 6 via a rotating shaft for adjusting the lamp's mounting angle. The bracket 6 can adopt a universal mounting structure such as a U-shaped bracket 6 or a single-arm bracket 6 to adapt to different installation conditions.

[0037] like Figure 1 , Figure 5 As shown, the driving power supply 4 is fixedly installed on the back of the heat sink housing 1. The driving power supply 4 operates in constant current mode, providing a stable constant voltage and constant current output to the LED light board 2, ensuring the operational stability of the lamp. The LED light board 2 is tightly bonded and fixed within the mounting cavity of the heat sink housing 1 using thermally conductive silicone grease. Figure 6 As shown, the heat sink housing 1 also has heat dissipation fins 11 integrally formed on the back, which can quickly dissipate the heat generated by the LED beads 24 during operation, effectively suppress the high temperature light decay of the LED beads 24, and improve the service life of the lamp.

[0038] like Figure 2 As shown, in this embodiment, the LED light panel 2 has three independent control areas: a constant-light area 21, a first light pattern area 22, and a second light pattern area 23. Each area is equipped with LED beads 24 arranged in a circular array. The LED beads 24 in the constant-light area 21, the first light pattern area 22, and the second light pattern area 23 are arranged in a staggered and uniform manner to avoid local color shift. The ratio of the number of LED beads 24 in the constant-light area 21, the first light pattern area 22, and the second light pattern area 23 is 1:1:1, and the rated power is kept consistent to ensure that the brightness deviation of the lamp output under different working modes is ≤5%. The LED beads 24 are dual-color temperature LED beads 24, and the color temperature of the dual-color temperature LED beads 24 covers between 2200K and 6500K, which can achieve full coverage of warm light, cool white light, and neutral light.

[0039] In this embodiment, the constantly lit area 21 remains constantly lit in all operating modes of the lamp, with no blackouts or flickering during gear switching, effectively improving the user experience and lamp stability. Based on the continuous lighting of the base structure of the constantly lit area 21, the utilization rate of LED beads can reach over 60% when a single control area of ​​the lamp is lit up, and the utilization rate of LED beads can reach 100% when all LED beads 24 in each control area are lit, significantly improving the overall luminous efficacy of the lamp.

[0040] like Figure 4 , Figure 5As shown, in this embodiment, the lens 3 is integrally injection molded from high-transmittance PC optical material, resulting in high structural strength and good light transmission. The lens 3 integrates at least two light distribution structures 31, which can be any combination of two or more of the following: symmetrical light pattern, polarized light pattern, Type III light pattern, and Type V light pattern. The light distribution angle of the light distribution structure 31 covers 15° to 90°. Each light distribution structure 31 corresponds one-to-one with the constant-light area 21, the first light pattern area 22, and the second light pattern area 23 of the LED light panel 2. This allows for individual shaping and distribution of the emitted light from each independent control area. Without mechanical displacement or replacement of the lens 3, different lighting combinations of control areas can be switched electronically to achieve multi-light pattern switching: 15°–30° narrow-angle focusing, 30°–60° medium-angle general-purpose, and 60°–90° wide-angle floodlight, adapting to different scene lighting needs. This embodiment does not limit the type of light distribution structure 31; any combination of two or more can be used.

[0041] like Figure 7 As shown, in this embodiment, the control module 5 includes an MCU controller 51, a DIP switch module 52, a PWM dimming circuit 53, and a MOS driver circuit 54. These four circuits are coupled sequentially and driven independently in different zones, forming a complete electronic control closed loop. The circuit hierarchy logic is as follows: the DIP switch module 52 is the signal input acquisition terminal; the MCU controller 51 is the logic operation and judgment core; the PWM dimming circuit 53 is the waveform modulation and shaping unit; and the MOS driver circuit 54 is the power amplification and output unit.

[0042] like Figure 7 , Figure 8 , Figure 9 As shown, the DIP switch module 52 includes an independent angle DIP switch 521 and a color temperature DIP switch 522. The angle DIP switch 521 and the color temperature DIP switch 522 are independently connected to different I / O ports of the MCU controller 51. Their signals do not interfere with each other, and their logic is not locked. They can independently adjust the light emission angle, color temperature, and output power adaptively, achieving freely combinable lighting modes. The MCU controller 51 is configured with multiple independent PWM output ports. Each PWM output port corresponds to an independent PWM dimming circuit 53 and a MOS drive circuit 54. Each MOS drive circuit 54 corresponds to a separate power supply circuit for the control area of ​​an LED bead 24, enabling completely independent on / off control of the three circuits: the constantly lit area 21, the first light pattern area 22, and the second light pattern area 23.

[0043] Specifically, after the lamp is powered on, the driving power supply 4 provides a stable operating voltage for the entire control circuit. The MCU controller 51 completes initialization and continuously reads the level signals of the two DIP switches. The MOS drive circuit corresponding to the constantly lit area 21 remains continuously conducting after power-on, unaffected by the DIP switch level switching, and always remains lit. The on / off state of the first light pattern area 22 and the second light pattern area 23 is precisely controlled by the MCU controller 51 according to the logic of each level. When the MCU controller 51 outputs a valid PWM signal, it is shaped and filtered by the PWM dimming circuit 53 and then input to the gate of the MOS drive circuit 54. The MOS transistor of the MOS drive circuit 54 is turned on, and the power supply circuit of the control area corresponding to the LED bead 24 is closed and lit. When the MCU controller 51 turns off the PWM output of the corresponding channel, the MOS transistor of the MOS drive circuit 54 is turned off, and the control area circuit of the LED bead 24 is disconnected and turned off.

[0044] The angle DIP switch 521 is configured with three operating modes:

[0045] In the first setting, the MCU controller 51 only enables the output channels of the PWM dimming circuit 53 corresponding to the constantly lit area 21 and the first light pattern area 22. Both MOS drive circuits 54 are turned on, the channel of the second light pattern area 23 is turned off, and the MOS transistors of the MOS drive circuit 54 are cut off. Only the LED beads 24 in the constantly lit area 21 and the first light pattern area 22 emit light, matching the narrow-angle light distribution structure 31 to form the first emission angle. The first emission angle is a narrow-angle light pattern, ranging from 15° to 30°, suitable for focused lighting, such as in stages and exhibition halls.

[0046] In the second mode, the MCU controller 51 only enables the output channels of the PWM dimming circuit 53 corresponding to the constant-on area 21 and the second light pattern area 23. The MOS circuit of the first light pattern area 22 is cut off, and only the LED beads 24 of the constant-on area 21 and the second light pattern area 23 emit light, forming a second light emission angle. The second light emission angle is a wide-angle light pattern with a range of 60° to 90°, which is suitable for wide-angle floodlighting, such as offices, workshops, and warehouses.

[0047] In the third setting, all three channels of the PWM dimming circuit 53 of the MCU controller 51 are enabled, and the MOS drive circuits 54 of the constant-on area 21, the first light pattern area 22, and the second light pattern area 23 are all turned on. All LED beads 24 emit light simultaneously, forming a third light-emitting angle. The third light-emitting angle is a mid-angle light pattern, with a range of 30° to 60°, which is suitable for conventional scenarios such as home lighting and corridor lighting.

[0048] In this embodiment, the color temperature DIP switch 522 is configured with three operating modes:

[0049] In the first setting, the MCU controller 51 only enables the output channels of the PWM dimming circuit 53 corresponding to the constant-on zone 21 and the first light pattern zone 22. The two MOS drive circuits 54 are turned on, the channel of the second light pattern zone 23 is turned off, and the MOS transistor of the MOS drive circuit 54 is turned off. Only the LED beads 24 of the constant-on zone 21 and the first light pattern zone 22 emit light, outputting a first color temperature of 2200K to 3000K. The first color temperature is warm light and is suitable for ambient lighting.

[0050] In the second mode, the MCU controller 51 only enables the output channels of the PWM dimming circuit 53 corresponding to the constant-on zone 21 and the second light pattern zone 23. The MOS transistor circuit of the first light pattern zone 22 is cut off, and only the LED beads 24 of the constant-on zone 21 and the second light pattern zone 23 emit light, outputting a second color temperature of 5000K to 6500K. The second color temperature is cool white light, which is suitable for high-definition work lighting, such as offices and workshops.

[0051] In the third setting, all three channels of the PWM dimming circuit 53 of the MCU controller 51 are enabled, and all MOS drive circuits 54 of the constant-brightness zone 21, the first light pattern zone 22, and the second light pattern zone 23 are turned on. The LED beads 24 emit light simultaneously, and warm light and cool white light are mixed in a specific ratio to output a mixed color temperature of 3500K to 4500K. This mixed color temperature is neutral light, suitable for comfortable general lighting scenarios, such as shopping malls and hospitals where color rendering and comfort are important. The color temperature setting's on / off logic and the angle setting's logic operate independently and in parallel, without being locked to each other, thus achieving free combination and control of both angle and color temperature.

[0052] In this embodiment, the MCU controller 51 pre-stores the standard PWM duty cycle parameters corresponding to each gear position. When different gear positions activate different numbers of LEDs, the MCU controller 51 fine-tunes the PWM duty cycle of the corresponding channel in real time. The PWM dimming circuit 53 precisely adjusts the effective average voltage of the output, and then the output is amplified by the MOS drive circuit 54 with constant current. This keeps the overall output power of the lamp balanced under different conduction combinations, avoiding problems such as excessive lighting power in a single zone and overload of lighting power in the constantly lit zone 21, the first light pattern zone 22, and the second light pattern zone 23. This achieves a stable dimming effect without sudden brightness changes or flicker. Specifically, during the operation of the lamp, the MCU controller 51 continuously scans the level changes of the DIP switch. If a gear position change is detected, the PWM output state is immediately refreshed, and the on / off state of the corresponding MOS drive circuit 54 is quickly switched, instantly completing the switching of the light emission angle and color temperature. The response speed is fast and the switching is smooth.

[0053] It is understood that this embodiment does not limit the switching control method between angle working mode and color temperature working mode. It can also be a variety of intelligent control methods such as wireless Bluetooth, DALI, DMX, APP, cloud platform remote control, human body sensing and timer, to adapt to the intelligent lighting needs of multiple scenarios.

[0054] like Figure 10 As shown, the present invention also discloses a control method for an LED lamp adapted to the above-mentioned electronically controlled angle, color temperature, and power adjustment, specifically including the following steps:

[0055] S1, Power-on initialization: After the lamp is connected to the power supply, the drive power supply 4 outputs a stable working voltage, and the MCU controller 51 automatically completes the system power-on initialization, including port initialization, PWM output port configuration, MOS drive circuit 54 IO port initialization, and register parameter reset; after initialization, the MCU controller 51 reads the level signal of the DIP switch module 52 in real time, independently collects the current gear status of the angle DIP switch 521 and the color temperature DIP switch 522, and locks the initial working gear parameters for this power-on;

[0056] S2, Mode Determination and Execution: The MCU controller 51 retrieves the internal preset control logic corresponding to the gear position. Based on the collected dual DIP switch gear position signals, it independently determines the working mode of the light emission angle and the working mode of the color temperature, and controls the on / off state of the constant-brightness zone 21, the first light pattern zone 22, and the second light pattern zone 23 in zones. Among them, the constant-brightness zone 21 always remains on under all determination results to prevent the screen from turning off during switching. The specific determination and execution logic is as follows:

[0057] Angle mode determination: If the angle DIP switch 521 is in the first position, the MCU controller 51 only controls the normally bright area 21 and the first light pattern area 22, and disconnects the second light pattern area 23, matching the light distribution structure 31 corresponding to the lens 3, and outputs a narrow-angle light pattern of 15° to 30°; if the angle DIP switch 521 is in the second position, the MCU controller 51 only controls the normally bright area 21 and the second light pattern area 23, and disconnects the first light pattern area 22, and outputs a wide-angle light pattern of 60° to 90°; if the angle DIP switch 521 is in the third position, the MCU controller 51 simultaneously controls all three control areas, and outputs a medium-angle light pattern of 30° to 60°.

[0058] Color temperature mode determination: If the color temperature DIP switch 522 is in the first position, the MCU controller 51 controls the normal brightness area 21 and the first light pattern area 22, outputting a warm color temperature of 2200K~3000K; if the color temperature DIP switch 522 is in the second position, the MCU controller 51 controls the normal brightness area 21 and the second light pattern area 23, outputting a cool white temperature of 5000K~6500K; if the color temperature DIP switch 522 is in the third position, the MCU controller 51 simultaneously controls the three control areas, outputting a neutral mixed color temperature of 3500K~4500K through the mixing of warm and cool LED beads. According to the currently matched working level, the MCU controller 51 retrieves the built-in standard PWM duty cycle parameters corresponding to the level and outputs a high-precision PWM dimming signal to the PWM dimming circuit 53. After waveform shaping and filtering by the PWM dimming circuit 53, the signal is sent to the MOS drive circuit 54. The MOS drive circuit 54 amplifies the low-voltage control signal and drives the power supply circuit of the corresponding control area to conduct, synchronously and adaptively matching the output power of each level, so as to stabilize the power of the lamp, eliminate the brightness change and flicker phenomenon during the level switching process, and ensure the consistency of light output in different working modes.

[0059] S3, Status Monitoring: During normal constant current operation of the lamp, the MCU controller 51 continuously scans the level status of the DIP switch module 52 at a fixed cycle to monitor the gear switching action in real time. When a change in the gear status of the angle DIP switch 521 or the color temperature DIP switch 522 is detected, the re-initialization mechanism is immediately triggered, returning to step S1 to re-acquire the latest gear status, and iteratively executing the mode determination and power matching logic of step S2 to quickly complete the seamless switching of the light emission angle and color temperature, realizing the real-time adjustable control function of the hardware DIP switch.

[0060] The above is a description of an LED lamp with electronically controlled angle, color temperature, and power adjustment, and its control method, to help understand the present invention. However, the implementation of the present invention is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of the present invention should be considered equivalent substitutions and are included within the protection scope of the present invention.

A control method for an LED lamp with electronically adjustable angle, color temperature, and power, characterized in that: Includes the following steps: S1, Power-on initialization: After the MCU controller is powered on, it completes initialization and reads the current gear status of the DIP switch module; S2, Mode Determination and Execution: The MCU controller executes the corresponding control logic according to the read gear status, selectively turning on the power supply circuit of the LED beads in the first light pattern area and / or the second light pattern area to achieve switching of different light emission angles and different color temperatures; at the same time, the MCU controller outputs a PWM signal according to the PWM duty cycle corresponding to the current gear status, which is amplified by the MOS drive circuit and then turns on the corresponding control area to synchronously match the output power of each gear. S3, Status Monitoring: If a change in the position of the DIP switch module is detected while the LED lamp is maintaining its current mode operation, the process returns to step S1 and is executed again to complete the switching between different light emission angles and different color temperatures.
