Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to an LED lighting device with intelligent color temperature regulation. Background Art

[0002] The color temperature of traditional incandescent lamps or energy-saving lamps is fixed. The color temperature of energy-saving lamps is richer, but the color temperature of these traditional light sources is fixed. Once manufactured, they cannot be adjusted. Generally, they can only be dimmed by adjusting the brightness, but cannot flexibly adjust the color temperature according to needs. At present, LED light sources are widely used due to their energy-saving and environmental protection advantages. The biggest advantage of LED light sources is that they can adjust not only the brightness, but also the color temperature and color. However, the adjustment switches of existing LED lamps are generally installed on the exposed surface of the lamp, which affects the appearance of the lamp. Some adjustment switches are installed on the embedded surface of the lamp body, which is not convenient to adjust. The lamp needs to be removed from the ceiling before it can be adjusted.

[0003] The currently disclosed Chinese patent CN109185819B discloses an embedded lamp with adjustable color temperature, comprising a base shell, the base shell having a cavity and being cylindrical, an LED lamp board fixedly arranged in the cavity of the base shell, the LED lamp board being in the shape of a disc, an edge of the LED lamp board being provided with a multi-position regulating switch, the regulating switch having a gear knob for switching between the gears, at least two groups of LED lamp beads with different color temperatures, each group of the LED lamp beads being arranged on the LED lamp board, each group of the LED lamp beads being correspondingly connected to the circuit of the LED lamp board through different gears of the regulating switch to realize on-off switching between each group of the LED lamp beads and in combination with any group of the LED lamp beads, the LED lamp board being electrically connected to the power supply of the embedded lamp, and a rotating face ring, the rotating face ring being rotatably connected to the base shell, and the inner side of the rotating face ring being provided with a driving member for toggling the gear knob when rotating.

[0004] According to the above patent, the above patent allows the user to rotate the rotating face ring outside the lamp, and the rotating face ring can toggle the gear knob of the adjustment switch to achieve switching between gears, so that the user can easily adjust the color temperature of the lamp by simply rotating the rotating face ring without disassembling the lamp. However, this method requires the user to manually rotate the rotating face ring to switch gears, which is difficult to manually adjust for lamps that are high or difficult to reach. In addition, this method can only open one gear at a time, which limits the user's fine control over color temperature adjustment. The user may not be able to obtain a color temperature between two preset gears, reducing the adjustment range of personalization and comfort. Therefore, there is a need for an LED lighting device that can automatically adjust the color temperature according to ambient light. Summary of the invention

[0005] In view of the problems existing in the prior art, an LED lighting device with intelligent color temperature adjustment is provided. The present invention uses a combination of LED lamp beads with different color temperatures to achieve the change of light color. At the same time, under the action of multiple light sensors, the changes in ambient light intensity and color temperature are captured more comprehensively. Through the cooperation of the control component and the switch component, it is ensured that the lighting device can dynamically adjust the color temperature according to the actual lighting conditions.

[0007] Preferably, a coaxial ring sleeve is fixedly provided on the annular surface of the lamp housing, and a plurality of light sensors for sensing the ambient light state are evenly provided on the ring sleeve along its circumferential direction, and the light sensors are electrically connected to the control element and the displacement driver.

[0008] Preferably, the switch element is a push-type switch structure, and the switch element has a sliding part and a pressing part. Each sliding groove of the annular surface is provided with a guide rail parallel to the axial center line direction of the annular surface. The sliding part is slidably arranged in the sliding groove and has a sliding shaft sliding along the direction of the guide rail. The end of the sliding shaft is provided with an anti-falling ring for preventing the switch element from falling off.

[0009] Preferably, the end of the guide rail extending outward has a fixed point, and the sliding part of the switch member has a movable point. A compression spring is fixed between the fixed point and the movable point. When the displacement drive is not started, the compression spring is in a state of not being acted upon by external force, so that the switch member is within the triggering range of the control member.

[0010] Preferably, the control member has a pressure plate with an annular structure and a pressure driver for driving the pressure plate to move, the pressure plate is coaxially arranged in the ring sleeve, a tension spring is fixedly provided between the pressure plate and the ring sleeve, the pressure plate has a pressure surface facing all switch members, when the pressure driver is not started, the tension spring is in a state of not being acted upon by external force, so that the pressure surface of the pressure plate is in a state of being away from the switch member.

[0011] Preferably, the pressure plate further has an outer peripheral surface with a gap between it and the ring sleeve, and a plurality of balls are rotatably provided on the inner side of the ring sleeve and are in sliding contact with the outer peripheral surface of the pressure plate.

[0012] Preferably, a protrusion is provided on the pressing surface of the pressure plate and at the position opposite to each pressing portion. When the pressure plate moves toward the switch member until the protrusion on the pressure plate contacts the pressing portion of the switch member, the pressing portion is in a squeezed state, so that the switch member is turned on to turn on a group of connected lamp beads.

[0013] Preferably, a plurality of valves fixedly connected to the pressure plate and having an anti-deflection effect are evenly arranged on the ring sleeve around its circumference.

[0014] Preferably, a buffer pad is fixedly provided on the annular surface of the lamp housing to prevent the pressing plate from having a hard contact with the annular surface, and when the pressing driver pushes the pressing plate, the buffer pad is in a state of being squeezed by the pressing plate.

[0015] Preferably, the fixing member has spring clips symmetrically arranged on both sides of the lamp housing for easy embedding in the ceiling.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention lights up through a combination of different lamp beads to achieve the adjustment of the color temperature required by the user. By activating the displacement driver, the position of the switch components around the ring surface is accurately controlled. As the switch components move, the switch components that do not need to be turned on are kept away from the triggering range of the control component, thereby selectively activating lamp beads with a single color temperature or different color temperatures, thereby emitting or blending the required light color. By mixing light sources of different color temperatures, a more natural and comfortable lighting environment can be created, reducing eye fatigue and improving the comfort of living or working space. Only necessary lamp bead combinations are activated, thereby avoiding unnecessary energy consumption, improving the energy efficiency ratio of the lighting device, and facilitating energy conservation and emission reduction.

[0018] 2. The present invention monitors the changes in ambient light in real time through light sensors, and utilizes the photoelectric effect to convert the light intensity information into electrical signals, and then adjusts the coordination of the control components and the switch components to realize the on-demand activation or sleep of LED lamp beads with different color temperatures. It not only creates a warm atmosphere by enhancing the warm light in a dim environment, but also increases the amount of cold color temperature light sources when the light is cold or sufficient to maintain visual naturalness and harmony. By sensing the ambient light, it can automatically reduce the brightness or turn off some lights when the natural light is sufficient, and increase the brightness in a dim environment, so as to achieve the purpose of energy saving. In addition, the layout of multiple light sensors can more accurately capture the changes in ambient light. Compared with a single light sensor, it provides more comprehensive ambient light information, makes the color temperature adjustment more delicate and accurate, and ensures that the lighting effect is perfectly integrated with the environment.

[0019] 3. The present invention monitors changes in the light environment through a light sensor, controls the switch parts that do not need to be activated to be moved by the displacement driver, away from the triggering range of the control part, and then the pressure driver is started, pushing the pressure plate to overcome the tension of the stretching spring and approach the switch part. The pressure surface of the pressure plate contacts and presses the switch part in the triggering range to activate the target color temperature lamp beads. In order to switch to a different color temperature, the pressure driver pauses and is reset by the stretching spring to prepare for the next round of selective activation. According to needs, the displacement driver rearranges the switch part position, and then the pressure driver is started again to complete the color temperature adjustment, thereby realizing adaptive adjustment of ambient light, ensuring the harmony and unity of the lighting effect and the environment, and improving the lighting quality.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-Figure 8 As shown, an LED lighting device with intelligent color temperature adjustment includes a lamp housing 1 and a lamp board 2 fixedly arranged on the lamp housing 1, wherein a plurality of groups of lamp beads 21 with different color temperatures are arranged on the lamp board 2, wherein the lamp housing 1 has an opening for the lamp beads 21 to emit light, wherein the lamp housing 1 is provided with a fixing member 3 for fixing the entire LED lighting device on the ceiling, and the LED lighting device also includes a color temperature adjustment mechanism 4 arranged at the opening of the lamp housing 1, wherein the color temperature adjustment mechanism 4 includes a switch member 41 electrically connected to each group of lamp beads 21, and a control member 42 capable of controlling all the switch members 41, and wherein the opening of the lamp housing 1 surrounds a The annular surface 11 is provided around the annular surface 11 for installing all the switch components 41. All the switch components 41 are evenly distributed along the circumferential direction of the annular surface 11. A slide groove for the switch component 41 to slide therein is provided at the position of each switch component 41. A displacement driver 12 for driving the switch component 41 to move is provided at the slide groove. When adjusting a single color temperature or blending a plurality of different color temperatures, the switch components 41 that do not need to be started are driven away from the control range of the control component 42 by the displacement driver 12, and then the control component 42 is started to trigger the switch components 41 within the control range, so that the lighting is in a state of preset effect.

[0033] When installing the lighting device, the user fixes the fixing member 3 on the lamp housing 1 to the ceiling or wall of the room. During use, the user issues an instruction through the remote control to specify the target color temperature to be achieved. The instruction is converted into an electrical signal and transmitted to the control system of the lighting device, which is not shown in the figure. After receiving the instruction, the control system quickly calculates the combination of lamp beads 21 required to achieve the target color temperature. After the calculation is completed, the control system activates the displacement drivers 12 located around the opening of the lamp housing 1. These displacement drivers 12 are connected to the switch members 41 evenly distributed on the annular surface 11. According to the calculation results, the respective positions are accurately adjusted. The switch members 41 slide along their respective slide grooves, and the displacement drivers 12 control the movement direction according to the instructions of the control signal. As the switch members 41 move, some switch members 41 that do not need to be turned on are away from the control member 42, so that only the required lamp beads 21 are turned on. In this way, different lamp beads 21 are selectively activated or turned off, thereby achieving accurate adjustment of the color temperature. When warm tones are required, more warm color temperature lamp beads 21 are lit, and when cool white tones are required, the proportion of cool color temperature lamp beads 21 is increased accordingly, or lamp beads 21 of different color temperatures are blended together to achieve the desired softer tones. Through the control of different groups of fine lamp beads 21, the lighting device can output light of the required color temperature. When multiple color temperatures need to be blended to achieve a specific atmosphere, lamp beads 21 of different color temperatures will be lit at the same time, and the color temperature blending between each other will form a light color that reaches the desired degree.

[0034] See also Figure 1-Figure 8 As shown, a coaxial ring sleeve 111 is fixedly disposed on the annular surface 11 of the lamp housing 1 , and a plurality of light sensors 5 for sensing the ambient light state are evenly disposed on the ring sleeve 111 along its circumferential direction. The light sensors 5 are electrically connected to the control member 42 and the displacement driver 12 .

[0035] Whenever the ambient light conditions change, the light sensor 5 installed on the ring sleeve 111 responds immediately. Based on the principle of photoelectric effect, it can convert the received light intensity into an electrical signal, capture the light intensity information of the current environment, and transmit the collected light intensity data to the displacement driver 12 and the control element 42. According to the information of the ambient light, the displacement driver 12 starts to work and accurately controls the switch element 41 to move along its preset slide. This step realizes the selective activation or shutdown of the lamp beads 21 with different color temperatures, that is, when the ambient light is dim, the switch element 41 controlling the warm color temperature lamp bead 21 is kept within the range triggered by the control element 42, and the other switch elements 41 are away from the triggering range of the control element 42 under the control of the displacement driver 12, so as to supplement the lack of ambient light and create a warm atmosphere. On the contrary, if the ambient light is sufficient and cold, the cold color temperature lamp bead 21 will be appropriately enhanced, and the switch element 41 controlling the cold color temperature lamp bead 21 will be kept within the range triggered by the control element 42, and the other switch elements 41 will be away from the triggering range of the control element 42 under the control of the displacement driver 12, so as to maintain the natural balance of light. With the fine movement of the switch 41, the lamp beads 21 in different areas of the lamp housing 1 are lit as needed, and the color temperature of cold and warm light is cleverly matched to create a rich and varied lighting effect. In different environments, the combination of lamp beads 21 can be adjusted according to the ambient light conditions to accurately match the user's visual and emotional needs. In addition, the layout of the multi-point light sensor 5 can more accurately capture the changes in ambient light. Compared with a single light sensor 5, it provides more comprehensive ambient light information, making the color temperature adjustment more delicate and accurate, ensuring that the lighting effect is perfectly integrated with the environment.

[0036] See also Figure 4-Figure 9 As shown, the switch member 41 is specifically a push-type switch structure, and the switch member 41 has a sliding portion 411 and a pressing portion 412. Each sliding groove of the annular surface 11 is provided with a guide rail 112 parallel to the axial center line direction of the annular surface 11, and the sliding portion 411 is slidably arranged in the sliding groove and the sliding portion 411 has a sliding shaft 4111 that slides along the direction of the guide rail 112, and the end of the sliding shaft 4111 is provided with an anti-falling ring 4112 for preventing the switch member 41 from falling off.

[0037] When the light sensor 5 detects changes in ambient light and sends a signal to the displacement driver 12, the displacement driver 12 pushes the sliding portion 411 of the switch member 41 to accurately slide along the guide rail 112 in the slide slot to a predetermined position according to the control signal, so that the switch member 41 that does not need to be turned on is away from the triggering range of the control member 42. The switch member 41 that needs to be turned on stays within the triggering range of the control member 42 until all the switch members 41 have completed regulation, and the control member 42 is restarted to trigger the required switch member 41 to turn on the corresponding lamp bead 21, that is, the pressing portion 412 of the switch member 41 is triggered by the control member 42, thereby turning on the lamp bead 21. In frequent displacement operations, the design of the anti-slip ring 4112 ensures that the switch member 41 will not fall off the guide rail 112 even in the case of fast or strong sliding, thereby maintaining the stability of operation.

[0038] See also Figure 4-Figure 9 As shown, the end of the guide rail 112 extending outward has a fixed point 1121, and the sliding part 411 of the switch member 41 has a movable point 1122. A compression spring 1123 is fixedly provided between the fixed point 1121 and the movable point 1122. When the displacement driver 12 is not started, the compression spring 1123 is in a state of not being acted upon by external force, so that the switch member 41 is within the triggering range of the control member 42.

[0039] When the displacement driver 12 is not activated, that is, the switch 41 is within the range that can be triggered by the control member 42, the compression spring 1123 is in a natural state and is not subjected to any external force, ensuring that the pressing portion 412 of the switch 41 is within the effective triggering range of the control member 42, and ensuring that the lighting device can maintain the default lighting state, that is, the initially set light output mode, when there is no external command. Once the ambient light change is sensed by the light sensor 5, the switch 41 of the lamp bead 21 that does not need to be turned on begins to move under the drive of the displacement driver 12, and it will accurately control the sliding portion 411 to move along the guide rail 112. In this process, the compression spring 1123 will be compressed with the displacement of the sliding portion 411 until the pressing portion 412 of the switch 41 is completely away from the triggering range of the control member 42. Then, the switch 41 within the triggering range is triggered by the control member 42, thereby emitting light of a suitable color temperature. When the regulating switch element 41 returns to its original position, the driving of the displacement driver 12 is stopped, and the compression spring 1123 is reset to drive the switch element 41 back to its original position, thereby facilitating the regulation of light of different color temperatures according to changes in ambient light.

[0040] See also Figure 4-Figure 10As shown, the control member 42 has a pressure plate 421 with an annular structure and a pressure driver 422 for driving the pressure plate 421 to move. The pressure plate 421 is coaxially arranged in the ring sleeve 111. A tension spring 423 is fixedly provided between the pressure plate 421 and the ring sleeve 111. The pressure plate 421 has a pressure surface 4211 facing all the switch members 41. When the pressure driver 422 is not started, the tension spring 423 is in a state of not being acted upon by external force, so that the pressure surface 4211 of the pressure plate 421 is in a state of being away from the switch member 41.

[0041] When the pressing driver 422 is not activated, the control member 42 is in an unactivated state. At this time, the tension spring 423 is kept at a natural length and is not affected by additional external forces, which results in a certain distance between the pressing surface 4211 of the pressing plate 421 and each switch member 41, ensuring that the lighting device will not be triggered by mistake without an operation instruction. When the light sensor 5 detects a change in the light environment and needs to adjust the lighting color temperature, as the switch member 41 that does not need to be turned on moves away from the trigger range of the control member 42 under the drive of the displacement driver 12, the pressing driver 422 is immediately started, pushing the pressing plate 421 to move axially along the ring sleeve 111 to resist the tension of the tension spring 423. As the pressing plate 421 approaches, its pressing surface 4211 gradually approaches and contacts the pressing portion 412 of the switch member 41. When the pressing surface 4211 precisely contacts the switch element 41 within the triggering range, that is, the pressing portion 412 of the switch element 41 is pressed, thereby realizing reliable activation of the target switch element 41, while the unselected switch element 41 continues to remain in an inactive state. This process ensures the selective control of the color temperature lamp beads 21 to adapt to the current ambient light requirements and adjust to a suitable color temperature state. When switching to different color temperatures, the pressing driver 422 first stops controlling the pressing plate 421, and under the action of the tension spring 423, the pressing plate 421 returns to its original position, and then the switch element 41 to be activated is reset to the range triggered by the controlled element 42, while the switch element 41 that does not need to be activated is driven away from the triggering range of the control element 42 by the displacement driver 12, and finally the pressing driver 422 activates the pressing plate 421 again, so that the switch element 41 within the triggered range is activated, thereby realizing the adjustment of the lamp beads 21 with different color temperatures.

[0042] See also Figure 4-Figure 10 As shown, the pressure plate 421 also has an outer peripheral surface 4212 with a gap between it and the ring sleeve 111 , and a plurality of balls 1111 are rotatably provided inside the ring sleeve 111 and are in sliding contact with the outer peripheral surface 4212 of the pressure plate 421 .

[0043] By introducing the ball bearings 1111, when the pressure plate 421 slides in the ring sleeve 111, it is no longer in the traditional surface contact, but is transformed into point contact, which greatly reduces the friction. Not only does it reduce the driving force required by the pressure driver 422 to push the pressure plate 421 to move, it also significantly reduces the wear during long-term use and extends the service life of the pressure plate 421. The low-resistance motion characteristics brought by the rolling of the ball bearings 1111 make the movement of the pressure plate 421 smoother and more stable. Even when quickly responding to light changes to adjust the color temperature, it can ensure the continuity and accuracy of the action, improve the user experience, and enhance the stability and reliability of the entire lighting device.

[0044] See also Fig. 9 and Fig.10 As shown, a protrusion 4121 is provided on the pressing surface 4211 of the pressing plate 421 and at the position opposite to each pressing portion 412. When the pressing plate 421 moves toward the switch member 41 until the protrusion 4121 on the pressing plate 421 contacts the pressing portion 412 of the switch member 41, the pressing portion 412 is in a squeezed state, so that the switch member 41 is turned on to turn on a group of connected lamp beads 21.

[0045] Each protrusion 4121 on the pressure plate 421 is precisely aligned with the pressing portion 412 of the corresponding switch member 41, ensuring that when the pressure plate 421 moves under the action of the pressing driver 422, the protrusion 4121 can directly and exclusively act on the pressing portion 412 of the target switch member 41, eliminating the risk of misoperation caused by position deviation. The introduction of the protrusion 4121 increases the pressure of the local contact area. When the pressure plate 421 moves to the target position, the protrusion 4121 will generate a concentrated downward force on the pressing portion 412 of the switch member 41, which is more effective than the plane contact to ensure the stable triggering of the switch member 41. Compared with the plane sliding, the point contact between the protrusion 4121 and the pressing portion 412 of the switch member 41 reduces unnecessary sliding friction, protects the surface of the pressure plate 421 and the pressing portion 412, and avoids the problem of poor contact caused by wear in long-term use, ensuring that each color temperature adjustment can respond quickly and accurately, bringing users a smooth and reliable lighting control experience.

[0046] See also Figure 4 , Figure 5 , Figure 8 and Fig.10 As shown, a plurality of valves 113 are evenly arranged around the circumference of the ring sleeve 111 and are fixedly connected to the pressure plate 421 to prevent deflection.

[0047] The valve 113 has a deformation capability, and each valve 113 is fixedly connected to the pressure plate 421 to form a multi-point constraint structure. When the pressure plate 421 moves axially along the ring sleeve 111 under the push of the pressure driver 422, the valve 113 effectively prevents the pressure plate 421 from any unnecessary rotational movement. Since the valve 113 has a certain elastic deformation capability, it means that during the movement of the pressure plate 421, the valve 113 can also be appropriately deformed to adapt to the movement of the pressure plate 421, which does not affect the rotation of the pressure plate 421 restricted by the valve 113, and ensures the smooth movement of the pressure plate 421, effectively avoiding the misalignment problem of the protrusion 4121 caused by the rotation of the pressure plate 421, and ensuring that the protrusion 4121 can accurately correspond to the corresponding switch member 41 pressing portion 412 in each operation, thereby improving the accuracy of control.

[0048] See also Figure 7 , Fig. 9 and Fig.10 As shown, a buffer pad 114 is fixedly disposed on the annular surface 11 of the lamp housing 1 to prevent the pressing plate 421 from having a hard contact therewith. When the pressing driver 422 pushes the pressing plate 421 , the buffer pad 114 is in a state of being squeezed by the pressing plate 421 .

[0049] When the pressing driver 422 pushes the pressing plate 421, the pressing surface 4211 of the pressing plate 421 will squeeze the buffer pad 114 instead of directly hitting the hard annular surface 11 of the lamp housing 1. The elastic deformation of the buffer pad 114 can absorb the pressure of the pressing plate 421, prevent noise and wear caused by hard collision, and enhance the durability of the lighting device.

[0050] See also Figure 1-Figure 8 As shown, the fixing member 3 has spring clips 31 symmetrically arranged on both sides of the lamp housing 1 for easy embedding into the ceiling.

[0051] When installing the lighting device, the user aligns the spring clip 31 on the lamp housing 1 with the opening on the ceiling, and gently pushes the spring clip 31 in its initial open state, adjusts the position of the lamp housing 1, and automatically locks the lamp housing 1 by relying on its own elasticity. The lighting device is then installed without the need for screws or other fasteners, greatly saving installation time and labor.

[0052] The present invention utilizes a combination of LED lamp beads 21 with different color temperatures to achieve the change of light color. The displacement driver 12 is activated by user needs, and the switch 41 fixed around the ring surface 11 is precisely adjusted to selectively connect the required lamp beads 21 to the power supply, while the lamp beads 21 away from the control component 42 are in an inactive state, thereby achieving the effect of adjusting the color temperature individually or in combination. At the same time, under the action of multiple light sensors 5, the changes in the intensity and color temperature of the ambient light are captured more comprehensively, and the photoelectric effect is used to convert the optical signal into an electrical signal, thereby adjusting the cooperation between the control component 42 and the switch 41. It ensures that the lighting device can be dynamically adjusted according to the actual lighting conditions, creating a lighting environment that can intelligently adjust the color temperature and brightness according to user needs and environmental changes, and improving the user's visual experience and the comfort of life and work.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
