Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, and in particular to a lighting device capable of self-adapting to ambient lighting. Background Art

[0002] At present, the height of various common lighting fixtures on the market is generally fixed when installed. But in fact, the home environments of different users are usually different. Most of the current home buildings have a bare floor height between 2.8m and 3.2m. Different decoration styles will lead to inconsistent floor heights. Taking the eye-protection floor lamp as an example, most of the eye-protection floor lamps have a height between 1.8m and 1.9m. Users with different floor heights will have different experiences when purchasing and using them. For example, in a room with a floor height of only 2.4m after ceiling decoration, the light emitted by the floor lamp hitting the ceiling will be weaker than the light reflected from the 3.2m ceiling. However, at the same time, using a 1.9m floor lamp in an environment with a floor height of 2.4m, the overall visual experience will make the user feel more depressed. When used in an environment with a floor height of 3.2m, the lamp will feel too short and not match the space well, and the reflected light will not be bright enough because the distance to the ceiling is too far. In addition, different users will also have different heights and different heights of desks and chairs, which will lead to different illumination of the light shining on the desktop. The height of school-age children is usually only about 1 meter, while the height of adolescents is almost the same as that of normal adults. There are also great differences in reading and learning habits. Therefore, existing lighting fixtures cannot automatically adjust the lighting height and brightness according to different environmental characteristics, resulting in poor lighting effects and user experience, poor applicability, and potential damage to the user's eyesight.

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1 and Figure 2 As shown, a lighting device 100 for adaptive ambient lighting according to an embodiment of the present invention includes a base 10, a lifting rod assembly 20, a light emitting assembly 30, a controller 40, a light sensor 50 and a scene perception sensor 60.

[0032] The lifting rod assembly 20 is arranged on the base 10, and the lifting rod assembly 20 can be telescopically adjusted in length in the height direction; the light-emitting assembly 30 is installed at the upper end of the lifting rod assembly 20 away from the base 10; the controller 40 is arranged on the light-emitting assembly 30 and is electrically connected to the light-emitting assembly 30; the light sensor 50 and the scene perception sensor 60 are respectively installed on the light-emitting assembly 30 and are respectively electrically connected to the controller 40.

[0033] The implementation of the embodiments of the utility model will have the following beneficial effects: when the lighting device 100 of the present scheme is working, since the light sensor 50 is provided with photosensitivity components inside, it can identify the illumination value of the current environment and feed back the real-time illumination value to the controller 40 for analysis and calculation. When the calculation result shows that the ambient illumination value is low, the controller 40 will increase the output current to the light-emitting component 30, so that the power of the light-emitting component 30 is increased, thereby improving the lighting brightness, even if the illumination value of the entire lamp is increased. When the calculation result shows that the illumination value of the current environment is high, the controller 40 will reduce the output current to the light-emitting component 30, so that the power of the light-emitting component 30 is reduced, thereby reducing the lighting brightness, even if the illumination value of the entire lamp is reduced. In addition, when the light-emitting component 30 is powered on and starts working, the scene perception sensor 60 will also work synchronously to perform a structural scan of the user's use environment and generate a 3D building model. The controller 40 also pre-stores an algorithm. The height, length, width and specific area of ​​the current use environment that requires light irradiation can be obtained through the 3D building model combined with the algorithm. When the height of the use space is large, the controller 40 outputs a command to the lifting support rod assembly 20 to control the lifting support rod assembly 20 to drive the light-emitting component 30 to rise to a suitable height. When the height of the use space is small, the controller 40 outputs a command to the lifting support rod assembly 20 to control the lifting support rod assembly 20 to drive the light-emitting component 30 to descend to a suitable height, thereby meeting the lighting needs of users of different heights and use environments of different heights, ensuring the lighting effect and user experience, and avoiding damage to the user's eyesight.

[0034] In an optional embodiment, the base 10 includes a bottom shell and a counterweight body, and the counterweight body is installed in the bottom shell. The counterweight body increases the weight of the base 10, so that the center of gravity of the entire lighting device 100 can be moved downward, ensuring that the lighting device 100 is placed more firmly and is not easily touched by external forces or easily tipped over when placed on an uneven ground.

[0035] Alternatively, the counterweight may be a stone, a metal block, or the like.

[0036] In an optional embodiment, the lifting rod assembly 20 is rotatably mounted on the base 10 via a rotating shaft, and the upper surface of the bottom shell is inwardly concave to form a receiving cavity, and the lifting rod assembly 20 in the retracted state can be received in the receiving cavity by rotation. Therefore, in the retracted state, the lifting rod assembly 20 can be completely received in the receiving cavity, making the entire lighting device 100 smaller in size, occupying less space, and having a more compact structure, which is easier to store, transport and carry.

[0037] In particular, magnetic buckles are installed on the side walls of the accommodating cavity, and metal blocks are installed on the outer walls of the lifting rod assembly 20. After the retracted lifting rod assembly 20 is loaded into the accommodating cavity, the magnetic buckles are magnetically fixed to the metal blocks to further fix the lifting rod assembly 20 and prevent the lifting rod assembly 20 from accidentally loosening and falling out of the accommodating cavity.

[0038] like Figure 1 As shown, in an optional embodiment, the lifting support rod assembly 20 includes a driving unit, a fixed support rod 21 and a movable support rod 22. The fixed support rod 21 is configured as a cylindrical structure, the movable support rod 22 is inserted into the cylindrical cavity of the fixed support rod 21 and can be telescopically moved relative to the fixed support rod 21, and the driving unit is arranged at the bottom of the cylindrical cavity of the fixed support rod 21 and is connected to the movable support rod 22.

[0039] The driving unit is used to output a linear driving force along the linear extension direction of the movable support rod 22, so as to drive the movable support rod 22 to extend to any desired length within the range outside the fixed support rod 21, thereby achieving the purpose of increasing the height of the adjusting light-emitting component 30, or drive the movable support rod 22 to retract to any desired length within the range inside the fixed support rod 21, thereby achieving the purpose of lowering the height of the adjusting light-emitting component 30.

[0040] For example, in an optional embodiment, the driving unit includes a driving motor, a transmission screw and a nut block, the driving shaft of the driving motor is connected to one end of the transmission screw, the nut block is threadedly connected to the outside of the transmission screw, and the nut block is connected to the movable support rod 22.

[0041] When adjusting the height of the light-emitting assembly 30, the driving motor drives the transmission screw to rotate, and the transmission screw can drive the nut block to move up or down along its axial direction through the thread pair, thereby driving the movable support rod 22 to move up or down through the nut block. The structure and working principle of the entire driving unit are simple, and the transmission accuracy is high, which helps to ensure the height position adjustment accuracy of the light-emitting assembly 30.

[0042] It is necessary to explain that in other optional embodiments, gear racks, scissor-type mechanisms, counterweight mechanisms, etc. can also be used to replace the above-mentioned transmission screw and nut block.

[0043] Furthermore, the driving unit further includes a rotary motor, a swing arm and a universal joint, wherein the rotary motor is mounted on the nut block, one end of the swing arm is connected to the rotating shaft of the rotary motor, and the other end of the swing arm is connected to the movable support rod 22 through the universal joint to drive the movable support rod 22 to rotate in the horizontal direction relative to the fixed support rod 21. This facilitates adjustment of the lighting angle in the horizontal direction, and achieves the purpose of meeting the lighting requirements in different directions by only arranging one lighting device 100 in the use environment, thereby greatly improving the use performance of the lighting device 100.

[0044] like Figure 1 As shown, in an optional embodiment, the light-emitting assembly 30 includes a light board 31, a first light-emitting lamp 32 and a second light-emitting lamp 33. The light board 31 is connected to one end of the movable support rod 22 away from the fixed support rod 21. The light board 31 has a first installation cavity for being set toward the ground and a second installation cavity for being set toward the ceiling. The first light-emitting lamp 32 is set in the first installation cavity, and the second light-emitting lamp 33 is set in the second installation cavity. Controlled by the controller 40, at least one of the first light-emitting lamp 32 and the second light-emitting lamp 33 can be lit and work at the same time.

[0045] The lamp board 31 is used as a bearing body to install and fix the first light emitting lamp 32 and the second light emitting lamp 33 to ensure the overall structural stability of the light emitting assembly 30. The lamp board 31 is specifically a PCB lamp board 31, which is assembled with the first light emitting lamp 32 and the second light emitting lamp 33 by welding, plugging, etc. to achieve electrical connection.

[0046] Optionally, the first light emitting lamp 32 and the second light emitting lamp 33 may be a light strip, a light bead, a light, etc. The first light emitting lamp 32 and the second light emitting lamp 33 may be of the same type or of different types.

[0047] When working, the first light 32 shines light toward the ceiling, and the light is reflected by the ceiling to form an effect similar to ambient light. The second light 33 shines light directly toward people or objects on the ground, thereby directly meeting the lighting needs. The first light 32 and the second light 33 can work together to take into account both lighting needs and lighting effects, thereby enhancing the user experience of the lighting device 100.

[0048] The brightness of the first light emitting lamp 32 and the second light emitting lamp 33 is controlled by the PWM control circuit 40 a of the controller 40 outputting currents of different powers to the light board 31 to control the overall brightness of the light emitting assembly 30 .

[0049] In addition, in an optional embodiment, the light emitting assembly 30 further includes a rotary driver, which is installed at one end of the movable support rod 22 away from the fixed support rod 21, and is connected to the light board 31 to drive the light board 31 to rotate in the vertical direction and / or horizontal direction to adjust the lighting angle. This can meet the multi-angle lighting needs of users in different usage occasions or different directions, and improve the lighting capacity.

[0050] It can be understood that when the rotary drive only uses a horizontally mounted motor, the light board 31 can be driven to drive the entire light-emitting assembly 30 to rotate vertically; when the rotary drive only uses a vertically mounted motor, the light board 31 can be driven to drive the entire light-emitting assembly 30 to rotate horizontally; when the rotary drive includes two motors, namely a horizontally mounted motor and a vertically mounted motor, it has the ability to rotate vertically and / or horizontally at the same time.

[0051] like Figure 1 As shown, further, the lighting device 100 for adaptive ambient lighting further includes a driver 70, which is disposed outside the base 10 and electrically connected to the controller 40. The driver 70 is used to convert the mains electricity into a low-voltage electrical output, thereby powering the controller 40, the drive motor and the light board 31.

[0052] In order to improve the protection capability of the driver 70 and enhance its performance, the outside of the driver 70 is wrapped with a waterproof insulating shell.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
