Technical Field
[0001] This utility model relates to the field of power control technology, and in particular to a lamp and its lighting parameter adjustment device, and an LED driver power supply. Background Technology
[0002] Currently, in order to enable luminaires to output various ranges of lighting parameters (lighting parameters may include power, color temperature, beam angle, etc.) from a single voltage, that is, to achieve the adjustment of the lighting parameters of the luminaires, the following two methods are usually used:
[0003] One approach is to use a combination of different power supplies and lighting fixtures to achieve the aforementioned function. However, this method is costly because it requires multiple power supplies.
[0004] Another approach is to design parallel redundant circuits within the lighting fixture. However, this method suffers from drawbacks such as high losses and high temperatures, resulting in low overall efficiency. Furthermore, the complex circuitry leads to high implementation costs and poor reliability.
[0005] In summary, common methods either rely on multiple hardware sets or use complex redundant circuits to achieve the above functions. Neither of these methods can simultaneously meet the requirements of low cost, high efficiency, and high reliability. Utility Model Content
[0006] The main purpose of this utility model is to provide a lighting parameter adjustment device for lamps, which aims to achieve the adjustment of lighting parameters of lamps in a low-cost, high-efficiency and high-reliability manner.

[0013] In one embodiment, the lighting parameter adjustment device for the lamp further includes:
[0014] Multiple voltage divider resistors, each with its first terminal grounded, and each resistor having a different resistance value;
[0015] A power DIP switch is provided, wherein the DIP switch terminal is connected to the control terminal of the control chip of the lamp, and each connection terminal of the power DIP switch is respectively connected to the second terminal of each voltage divider resistor.

[0017] In addition, to achieve the above objectives, this utility model also provides a lamp, which includes LED beads and an LED driver power supply as described above.
[0018] In one embodiment, the LED beads are arranged in a preset shape.
[0019] In one embodiment, when the light angles of the LED beads are not uniform, LED beads with the same light angle form an angle LED bead combination, and LED beads with the same color temperature form a color temperature LED bead combination.
[0020] In one embodiment, when all the LED beads have the same light angle, the lamp further includes multiple lenses, each of which has a different light angle;
[0021] After the LED beads are arranged, each pair of adjacent LED beads forms an angled LED bead combination, and each LED bead in the angled LED bead combination is located inside the lens.
[0022] In one embodiment, the preset shape is a circle or a strip.
[0023] This utility model provides a lighting parameter adjustment device for a lamp, including a color temperature DIP switch and an angle DIP switch. The DIP switch is connected to the first electrode of the LED driver power supply of the lamp, and each connection terminal of the color temperature DIP switch is connected to a different color temperature LED bead combination in the lamp, used to switch the color temperature LED bead combination connected to the first electrode of the LED driver power supply in the lamp to adjust the color temperature of the lamp.

Detailed Implementation
[0039] 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.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0042] Lighting parameters of a luminaire are a series of indicators used to measure and describe its luminous characteristics, lighting effects, and related performance. These parameters may include, but are not limited to, power, color temperature, and / or beam angle. Among them, beam angle refers to the angle of light illumination, also known as the "beam angle" or "light emission angle".
[0043] Currently, in order to enable luminaires to output various lighting parameters from a single voltage, that is, to achieve the adjustment of the lighting parameters of the luminaires, the following two methods are usually used:
[0044] One approach is to use a combination of different power supplies and lighting fixtures to achieve the aforementioned function. However, this method is costly because it requires multiple power supplies.
[0045] Another approach is to design parallel redundant circuits within the lighting fixture. Specifically, this can be achieved using a redundant circuit consisting of two DC power supply modules, four MOSFETs, and two controllers, or by connecting diodes in parallel at the output of the power supply modules. However, this method suffers from drawbacks such as high losses and high temperatures, resulting in low overall efficiency. Furthermore, the complex circuitry leads to high implementation costs and poor reliability.
[0046] In summary, common methods either rely on multiple hardware sets or use complex redundant circuits to achieve the above functions. Neither of these methods can simultaneously meet the requirements of low cost, high efficiency, and high reliability.
[0047] Based on this, the present invention provides a lighting parameter adjustment device for a lamp. In the first embodiment of the present invention, please refer to... Figure 1 The lighting parameter adjustment device for the luminaire may include:
[0048] Color temperature DIP switch K1, the DIP terminal of color temperature DIP switch K1 is connected to the first pole of the LED driver power supply of the lamp, and each connection terminal of color temperature DIP switch K1 is connected to each color temperature LED bead combination in the lamp, used to switch the color temperature LED bead combination connected to the first stage V1 of the LED driver power supply in the lamp to adjust the color temperature of the lamp.
[0049] Angle DIP switch K2 has its DIP terminals connected to the second pole of the LED driver power supply. Each terminal of the angle DIP switch K2 is connected to a different angle LED combination in the luminaire. It is used to switch the angle LED combination connected to the second pole V2 of the LED driver power supply in the luminaire to adjust the light angle of the luminaire.
[0050] Each color temperature LED combination corresponds to a different color temperature, and each angle LED combination corresponds to a different light angle.
[0051] It should be noted that the DIP switch K1 for color temperature can be connected to either the positive or negative terminal of the LED driver power supply; similarly, the DIP switch K2 for angle can also be connected to either the positive or negative terminal of the LED driver power supply. Specifically, when the DIP switch K1 for color temperature is connected to the positive terminal of the LED driver power supply, the DIP switch K2 for angle must be connected to the negative terminal. Conversely, when the DIP switch K1 for color temperature is connected to the negative terminal, the DIP switch K2 for angle must be connected to the positive terminal.
[0052] Additionally, it should be noted that the number of connection terminals for the color temperature DIP switch K1 can be the same as the number of color temperature LED combinations included in the luminaire; similarly, the number of connection terminals for the angle DIP switch K2 can be the same as the number of angle LED combinations included in the luminaire. Therefore, when selecting the color temperature DIP switch K1 and angle DIP switch K2, the type of DIP switch K1 and angle DIP switch K2 can be flexibly chosen based on the actual combination of color temperature LEDs and angle LEDs in the luminaire.
[0053] In one feasible implementation, when the number of color temperature LED combinations in the lamp is two sets, the color temperature DIP switch K1 can be... Figure 2 The structure is shown. Specifically, pins 1, 4, 6, and 8 of the color temperature DIP switch K1 together form the DIP terminal of the color temperature DIP switch K1, which is connected to the first terminal V1 of the LED driver power supply; pins 3 and 7 of the color temperature DIP switch K1 together form one connection terminal of the color temperature DIP switch K1, which is connected to a color temperature LED bead combination A in the lamp; pin 2 of the color temperature DIP switch K1 forms the other connection terminal of the color temperature DIP switch K1, which is connected to another color temperature LED bead combination B in the lamp.
[0054] In one feasible implementation, when the number of angle LED combinations in the luminaire is two sets, the angle DIP switch K2 can be... Figure 3The structure is shown below. Specifically, pins 1, 4, 6, and 8 of the angle DIP switch K2 together form the DIP terminal of the angle DIP switch K2, which is connected to the second terminal V2 of the LED driver power supply; pins 3 and 7 of the angle DIP switch K2 together form one connection terminal of the angle DIP switch K2, which is connected to one angle LED combination C in the lamp; pin 2 of the angle DIP switch K2 forms the other connection terminal of the angle DIP switch K2, which is connected to another angle LED combination D in the lamp.
[0055] Furthermore, it should be noted that the LED chips in the lamp are grouped according to color temperature, that is, LED chips with the same color temperature are grouped together to obtain combinations of chips with different color temperatures. The LED chips in the lamp are also grouped according to beam angle, that is, LED chips with the same beam angle are grouped together to obtain combinations of chips with different beam angles.
[0056] For example, suppose the lamp includes four LED beads, LED1 to LED4. The first LED bead, LED1, has a cool white color temperature and a beam angle of 60°; the second LED bead, LED2, has a cool white color temperature and a beam angle of 120°; the third LED bead, LED3, has a warm white color temperature and a beam angle of 120°; and the fourth LED bead, LED4, has a warm white color temperature and a beam angle of 60°. After grouping, we can obtain combinations of LED beads for each color temperature including [LED1, LED2] and [LED3, LED4], and combinations of LED beads for each beam angle including [LED1, LED4] and [LED2, LED3].
[0057] Building upon the above example, to further understand the principle that "adjusting the color temperature and beam angle of a lamp can be achieved by switching the color temperature DIP switch K1 and the angle DIP switch K2," let's take the example where the DIP switch K1 is connected to the positive terminal V+ of the LED driver power supply, and the DIP switch K2 is connected to the negative terminal V- of the LED driver power supply. Please refer to... Figure 4 . Specifically:
[0058] When the color temperature DIP switch K1 is set to V+, and color temperature LED combinations [LED1, LED2] and [LED3, LED4] are connected in the lamp, and the angle DIP switch K2 is set to V-, and angle LED combinations [LED1, LED4] and [LED2, LED3] are connected in the lamp, all four LEDs LED1 to LED4 will be lit. This allows the color temperature to be adjusted to a mixture of cool white and warm white.
[0059] When the color temperature DIP switch K1 is set to V+, the positive terminal of the LED driver power supply is connected to both the color temperature LED combination [LED1, LED2] and the color temperature LED combination [LED3, LED4] in the lamp, and the angle DIP switch K2 is set to V-, the negative terminal of the LED driver power supply is connected to the angle LED combination [LED2, LED3] in the lamp, the second LED LED2 and the third LED LED3 will be lit. This allows the color temperature to be adjusted to a mixture of cool white and warm white, and the light angle to be adjusted to 120°.
[0060] When the color temperature DIP switch K1 is set to V+, and color temperature LED combination [LED1, LED2] and color temperature LED combination [LED3, LED4] are connected in the lamp, and the angle DIP switch K2 is set to V-, and angle LED combination [LED1, LED4] are connected in the lamp, the first LED LED1 and the fourth LED LED4 will be lit. This allows the color temperature to be adjusted to a mixture of cool white and warm white, and the light angle to be adjusted to 60°.
[0061] When the color temperature DIP switch K1 is set to V+, the positive terminal of the LED driver power supply is connected to the color temperature LED combination [LED1, LED2] in the lamp, and the angle DIP switch K2 is set to V-, the negative terminal of the LED driver power supply is connected to both the angle LED combination [LED1, LED4] and the angle LED combination [LED2, LED3] in the lamp, the first LED LED1 and the second LED LED2 will be lit, thereby adjusting the color temperature to cool white;
[0062] When the color temperature DIP switch K1 is set to V+, the positive terminal of the LED driver power supply is connected to the color temperature LED combination [LED1, LED2] in the lamp, and the angle DIP switch K2 is set to V-, the negative terminal of the LED driver power supply is connected to the angle LED combination [LED2, LED3] in the lamp, the second LED LED will be lit. This allows the color temperature to be adjusted to cool white and the light angle to be adjusted to 120°.
[0063] When the color temperature DIP switch K1 is set to V+, the positive terminal of the LED driver power supply is connected to the color temperature LED combination [LED1, LED2] in the lamp, and the angle DIP switch K2 is set to V-, the negative terminal of the LED driver power supply is connected to the angle LED combination [LED1, LED4] in the lamp, the first LED LED will be lit, thereby adjusting the color temperature to cool white and the light angle to 60°;
[0064] When the color temperature DIP switch K1 is set to V+, the positive terminal of the LED driver power supply is connected to the color temperature LED combination [LED3, LED4] in the lamp, and the angle DIP switch K2 is set to V-, the negative terminal of the LED driver power supply is connected to the angle LED combination [LED2, LED3] in the lamp, the third LED LED will be lit. This allows the color temperature to be adjusted to warm white and the light angle to be adjusted to 120°.
[0065] When the color temperature DIP switch K1 is set to V+, the positive terminal of the LED driver power supply is connected to the color temperature LED combination [LED3, LED4] in the lamp, and the angle DIP switch K2 is set to V-, the negative terminal of the LED driver power supply is connected to the angle LED combination [LED1, LED4] in the lamp, the fourth LED LED will be lit. This allows the color temperature to be adjusted to warm white and the light angle to be adjusted to 60°.
[0066] It should be noted that the above examples are only used to help understand the implementation principle of the lighting parameter adjustment device of the lamp of this utility model, and do not constitute a specific limitation on the structure of the lighting parameter adjustment device of the lamp.
[0067] As described above, this embodiment uses a color temperature DIP switch K1 between the first electrode V1 of the LED driver power supply and each color temperature LED combination, and an angle DIP switch K2 between the second electrode V2 of the LED driver power supply and each angle LED combination. Therefore, by switching the color temperature DIP switch K1 and the angle DIP switch K2, the user can switch the color temperature LED combination connected to the first electrode V1 of the LED driver power supply in the luminaire, and the angle LED combination connected to the second electrode V2 of the LED driver power supply in the luminaire, thereby adjusting the color temperature and light angle of the luminaire.
[0068] Therefore, the lighting parameter adjustment device for lamps provided in this embodiment, compared with conventional technical means, only requires one LED driver power supply and does not require parallel redundant circuits to adjust the color temperature and beam angle of the lamp. Thus, this embodiment can achieve the adjustment of the lighting parameters of lamps in a low-cost, high-efficiency, and highly reliable manner.
[0069] Based on the first embodiment described above, a second embodiment of the lighting parameter adjustment device for the lamp of this utility model is proposed. For the second embodiment, please refer to... Figure 5 The lighting parameter adjustment device for the luminaire may also include:
[0070] Multiple voltage divider resistors R1 to Rn are used, with the first terminal of each resistor R1 to Rn grounded to DIMGND. The resistance values of each resistor R1 to Rn are different.
[0071] The power DIP switch K3 has its DIP terminals connected to the control terminals of the lamp's control chip U1. Each terminal of the power DIP switch K3 is connected to the second terminal of each voltage divider resistor R1 to Rn. It is used to switch the voltage divider resistors connected to the control terminals of the control chip U1, or to leave the control terminals of the control chip U1 in neutral, so as to adjust the power of the lamp.
[0072] It should be noted that the number of connection terminals of the power DIP switch K3 can be the same as the number of each voltage divider resistor R1 to Rn. Based on this, when selecting the power DIP switch K3, the type of DIP switch K3 can be flexibly selected according to the setting of the voltage divider resistors.
[0073] In one feasible implementation, when two voltage divider resistors R1 to R2 are provided, the power DIP switch K3 can be... Figure 6 The structure is shown. Specifically, pins 2 and 6 of the power DIP switch K3 together form the DIP terminal of the power DIP switch K3, which is connected to the control terminal BM+ of the control chip U1; pins 3 and 7 of the power DIP switch K3 together form one connection terminal of the power DIP switch K3, which is connected to the second terminal of the voltage divider resistor R1; pins 4 and 8 of the power DIP switch K3 together form the other connection terminal of the power DIP switch K3, which is connected to the second terminal of the voltage divider resistor R2.
[0074] Additionally, it should be noted that the circuit structure of the control chip U1 for the lighting fixture can be referenced. Figure 7 In the diagram, BM+ is the control terminal of control chip U1. Based on this, let's take an example with two voltage divider resistors R1 and R2, R1 with a resistance of 20KΩ and R2 with a resistance of 10KΩ, resistors RP1 and RP2 connected to pin 19 of control chip U1 both with a resistance of 10KΩ, and a power supply of 5VB connected to pin 19 of control chip U1, with a default output power of 300W. Specifically:
[0075] When the power DIP switch K3 is set to the neutral position of the control terminal BM+ of the control chip U1, 5VB directly enters pin 19 of the control chip U1 through resistor RP2, so the voltage entering the control chip U1 is 5V. At this time, the output power of pin 19 of the control chip U1 is 300W.
[0076] When the power DIP switch K3 is set so that the control terminal BM+ of the control chip U1 is connected to the voltage divider resistor R1, 5VB needs to be divided by the voltage divider resistor R1 through the resistor RP2 to enter pin 19 of the control chip U1, so the voltage entering the control chip U1 is 3.3V. At this time, the output power of pin 19 of the control chip U1 is 200W.
[0077] When the power DIP switch K3 is switched so that the control terminal BM+ of the control chip U1 is connected to the voltage divider resistor R2, 5VB needs to be divided by resistor RP2 and voltage divider resistor R2 to enter pin 19 of the control chip U1, so the voltage entering the control chip U1 is 2.5V. At this time, the output power of pin 19 of the control chip U1 is 100W.
[0078] Understandably, after changing the voltage at pin 19 of control chip U1 by switching the power DIP switch K3, control chip U1 will output a corresponding control signal based on the changed voltage. This control signal can then be used to change the output current of the LED driver power supply by altering the resistance value of the sampling resistor or the reference value of the output current, thereby adjusting the power.
[0079] As described above, this embodiment connects a power DIP switch K3 to the control chip U1 of the lamp, and connects multiple voltage divider resistors R1 to Rn to the power DIP switch K3. Therefore, by switching the power DIP switch K3, the user can change the voltage divider resistors connected to the control terminal of the control chip U1, or leave the control terminal of the control chip U1 in neutral, thereby adjusting the power of the lamp.
[0080] Therefore, the lighting parameter adjustment device for lamps provided in this embodiment, compared to conventional techniques, only requires a single LED driver power supply and eliminates the need for parallel redundant circuits to adjust the lamp's power. Thus, this embodiment achieves low-cost, high-efficiency, and highly reliable adjustment of lamp lighting parameters.
[0081] In addition to the method described in this embodiment, which uses the power DIP switch K3 to change the voltage at pin 19 of the control chip U1 to regulate power, other embodiments can also use the power DIP switch K3 to directly change the sampling resistor of the LED driver power supply to adjust the output current of the LED driver power supply, thereby regulating power. Alternatively, the power DIP switch K3 can be used to directly change the reference current of the LED driver power supply to adjust the output current of the LED driver power supply, thus regulating power.
[0082] This utility model embodiment also provides an LED driver power supply, which includes the lighting parameter adjustment device for the above-described lamp. The structure of the lighting parameter adjustment device for the lamp can be referred to the above embodiment, and will not be repeated here.
[0083] The LED driver power supply provided in this embodiment can achieve the adjustment of lighting parameters of lamps in a low-cost, high-efficiency, and highly reliable manner. Since the LED driver power supply in this embodiment includes all the technical solutions of all embodiments of the above-mentioned lighting parameter adjustment device for lamps, and the achieved technical effects are exactly the same, it will not be described again here.
[0084] This utility model embodiment also provides a lamp, which includes LED beads and the aforementioned LED driver power supply. The structure of the LED driver power supply can be referred to in the above embodiment, and will not be repeated here.
[0085] In one feasible implementation, in order to achieve unified control of each LED bead to facilitate subsequent adjustment of light angle and color temperature, the LED beads can be arranged in a preset shape.
[0086] It should be noted that the preset shape can be circular, strip-shaped, or other shapes, and this embodiment does not specifically limit it. When arranging according to the preset shape, the light angle can be considered as the arrangement basis. For example, taking a lamp that includes four LED beads LED1 to LED4, where the first LED bead LED1 has a cool white color temperature and a light angle of 60°, the second LED bead LED2 has a cool white color temperature and a light angle of 120°, the third LED bead LED3 has a warm white color temperature and a light angle of 120°, and the fourth LED bead LED4 has a warm white color temperature and a light angle of 60°, then when arranging in a circular shape, the smaller light angles can be arranged first, followed by the larger light angles, thus forming a shape like... Figure 8 The arrangement shown is as follows: the first ring is the first LED bead LED1, the second ring is the fourth LED bead LED4, the third ring is the second LED bead LED2, and the fourth ring is the third LED bead LED3.
[0087] For example, after arranging them in a strip shape, they can form something like... Figure 9 The arrangement shown is as follows: the first column is the first LED bead LED1, the second column is the fourth LED bead LED4, the third column is the second LED bead LED2, and the fourth column is the third LED bead LED3.
[0088] Furthermore, when arranging LEDs according to a preset shape, color temperature can also be considered as the arrangement basis. For example, LEDs with a cool white color temperature can be arranged first, followed by LEDs with a warm white color temperature. This embodiment does not impose any specific limitations on this.
[0089] In one feasible implementation, when the light angles of each LED bead are not uniform, LED beads with the same light angle form an angle LED bead combination, and LED beads with the same color temperature form a color temperature LED bead combination.
[0090] In another feasible implementation, when all LED beads have the same light angle, the lamp also includes multiple lenses, each with a different light angle; after the LED beads are arranged, each pair of adjacent LED beads forms an angled LED bead combination, and each LED bead in the angled LED bead combination is located inside the lens.
[0091] It should be noted that each combination of LED beads at different angles is set up in a one-to-one correspondence with each lens.
[0092] For example, consider a lighting fixture comprising four LED beads (LED1-LED4) with the same beam angle. The color temperature of the first LED bead (LED1) is cool white, the color temperature of the second LED bead (LED2) is cool white, and the color temperature of the third LED bead (LED3) and the fourth LED bead (LED4) is warm white. These LED beads are arranged in a circular shape to form... Figure 8 After the arrangement shown, the first LED LED1 and the fourth LED LED4 are adjacent to each other and can form an angled LED combination. They are placed inside a lens with a first light angle (e.g., 60°) to form an angled LED combination with a corresponding light angle of the first angle. The second LED LED2 and the third LED LED3 are adjacent to each other and can form another angled LED combination. They are placed inside a lens with a second light angle (e.g., 120°) to form an angled LED combination with a corresponding light angle of the second angle.
[0093] The lighting fixture provided in this embodiment can achieve adjustment of lighting parameters in a low-cost, high-efficiency, and highly reliable manner. Since the lighting fixture in this embodiment includes all the technical solutions of all the above-described LED driver power supply embodiments, and the achieved technical effects are exactly the same, further details are omitted here.
[0094] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
