In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to.

As shown in fig. 1 to 5, the present invention provides an illumination structure 10, which may include a first light source 100, a first photo sensor 101, a second light source 200, a second photo sensor 201, and a processing module 300; the first light source 100 is used for providing a first illumination light towards the first areas Z1, Z1 ', the first light sensor 101 is used for sensing the illumination brightness of the first areas Z1, Z1 ', the second light source 200 is used for providing a second illumination light towards the second areas Z2, Z2 ', the second light sensor 201 is used for sensing the illumination brightness of the second areas Z2, Z2 ', the processing module 300 is coupled to the first light source 100, the second light source 200, the first light sensor 101, and the second light sensor 201, and the processing module 300 is used for adjusting the illumination parameter of the first light source 100 according to the illumination brightness of the first areas Z1, Z1 ' and adjusting the illumination parameter of the second light source 200 according to the illumination values of the first areas Z1, Z1 ' and the illumination brightness of the second areas Z2, Z2 '.
It should be noted that the illumination brightness may include an ambient light brightness and an illuminance value, for example, when the light source is not turned on, the light sensor senses the ambient light brightness, and when the light source is turned on, the light sensor senses the illuminance value in the corresponding range. For convenience of description, the following description will take the light emitting intensity or the light illumination of the light source as a representative parameter to illustrate the illumination parameters, but the present invention is not limited thereto, for example, the processing module 300 can also flexibly adjust and control the color temperature, the color, and the like of the first light source 100 or the second light source 200 according to the sensing result.
In an embodiment, the first light source 100 and the second light source 200 may be any one or combination of incandescent lamps, halogen lamps, and LED light sources, the first photo sensor 101 and the second photo sensor 201 may be any one or combination of photo resistors and photodiodes, and the processing module 300 coupled to the above elements may be a micro-control chip and its peripheral circuits.
In practical implementation, the lighting structure 10 may be applied to a lighting device, as shown in fig. 2 to 5, the lighting device may be a table lamp 20 for a table or a clip lamp 30 for clipping a screen 40. The first light source 100 and the second light source 200 are independent of each other and correspond to different regions (directions), and similarly, the first light sensor 101 and the second light sensor 201 correspond to different regions (directions). The first regions Z1 and Z1 'may be work regions (e.g., desk top, keyboard and mouse region), and the second regions Z2 and Z2' may be background regions (e.g., background wall surface), i.e., the first light source 100 is a main light source and the second light source 200 is an auxiliary light source (background light source). It is understood that the first light sources 100 located in the first zones Z1, Z1 'may be close to the user, while the second light sources 200 located in the second zones Z2, Z2' may be relatively far from the user. In other words, the first light source 100 is used to provide light to the working area of the user to form a main lighting area, and the second light source 200 is used to make proper adjustment according to the illumination of the main lighting area to form an auxiliary lighting area, which can reduce the contrast glare between the ambient environment and the main lighting area, thereby achieving the technical effect of protecting the eyes.
Specifically, after the lighting structure 10 is powered, the first photo sensor 101 first senses the ambient light brightness of the first areas Z1 and Z1 ', the processing module 300 turns on the first light source 100 and controls the illuminance value thereof according to the ambient light brightness of the first areas Z1 and Z1', then the first photo sensor 101 again senses the ambient light brightness and/or illuminance value of the first areas Z1 and Z1 ', and the processing module 300 adjusts the illumination parameter of the first light source 100 again according to the current ambient light brightness or illuminance value of the first areas Z1 and Z1'; then, the second photo sensor 201 senses the ambient light brightness of the second zones Z2, Z2 ', the processing module 300 turns on the second light source 200 and controls the illumination value thereof according to the ambient light brightness of the second zones Z2, Z2', then the second photo sensor 201 senses the ambient light brightness and/or illumination value of the second zones Z2, Z2 'again, and the processing module 300 adjusts the illumination parameter of the second light source 200 again according to the current ambient light brightness or illumination value of the second zones Z2, Z2'. The processing module 300 may preset a mapping relationship between the ambient light brightness (or illuminance value) of each region and the illuminance value of each light source, and adjust the first light source 100 and the second light source 200 in real time according to the mapping relationship, thereby achieving a light compensation balance mechanism.
Further, the first areas Z1, Z1 'do not overlap with the second areas Z2, Z2', and the first illumination light ray does not intersect with the second illumination light ray. That is, the primary illumination zone and the secondary illumination zone are independent of each other.
In one embodiment, the sensing directions L2 and L2 'of the first photo sensor 101 may be the same as the irradiation directions L1 and L1' of the first illumination light, and the sensing directions L4 and L4 'of the second photo sensor 201 may be the same as the irradiation directions L3 and L3' of the second illumination light.
Specifically, as shown in fig. 2 and 4, when the lighting device is a desk lamp 20, it may include a lamp socket 210, a bracket 220 connected to the lamp socket 210, and the lighting structure 10. It will be appreciated that the lighting structure 10 is disposed at an end of the support 220 away from the lamp socket 210, and the first lighting light is directed towards the lamp socket 210 (working area) in the direction L1, while the second lighting light is directed towards the background area. As can be seen, the working area (the first area Z1) is located on the same side as the lamp socket 210 and the bracket 220, and the background area (the second area Z2) is located on different sides of the lamp socket 210 and the bracket 220.
Preferably, the lighting structure 10 further includes a lamp cover 320, and the first light source 100, the second light source 200, the first light sensor 101 and the second light sensor 201 are disposed on the lamp cover 320. The lamp housing 320 may have a housing having an accommodating space, the first light source 100, the first photo sensor 101, the second light source 200, and the second photo sensor 201 may be mounted in the accommodating space, and the housing may be provided with through holes or transparent shields at positions corresponding to the components to ensure normal operation of the light source and the photo sensors. It is understood that the installation manners of the first light source 100, the first light sensor 101, the second light source 200, the second light sensor 201 and the processing module 300 can be determined according to actual requirements, and the invention is not limited herein as long as the respective setting purposes can be achieved.
In another embodiment, as shown in fig. 3 and 5, when the lighting device is a hanging lamp (clip lamp 30) clamped on the screen 40, the screen 40 may have a front surface (display surface), a rear surface and an upper surface connecting the front surface and the rear surface, and the lighting device may include the lighting structure 10 and the clamping body. The clamping body includes a first clamping piece and a second clamping piece, the first clamping piece has a first clamping portion 310 and a lamp connecting portion 311311 connected to the first clamping portion 310, the lamp connecting portion 311311 is connected to the first light source 100, the second clamping piece has a second clamping portion 320, wherein the second light source 200 is disposed on the clamping body, when the lighting device clamps the screen 40, the first clamping portion 310 is used for abutting against the front surface, the second clamping portion 320 is used for abutting against the rear surface, so that the first light source 100 is located above the upper surface, and the first region Z1 'and the second region Z2' are located on two different sides of the screen 40. Specifically, the first zone Z1 'is located at a zone toward which the front surface of the screen 40 faces, and the second zone Z2' is located at a zone toward which the rear surface of the screen 40 faces.
Specifically, the front surface of the screen 40 faces the first zone Z1 'to provide a display for users to watch, and when the first light source 100 of the clip light 30 is turned on, it is used to emit light toward the first zone Z1' to provide illumination in front of the screen 40. The rear surface of the screen 40 faces the second zone Z2 'and has a distance from a reference object (e.g., a wall) in the second zone Z2'. When the second light source 200 provided on the holding body is turned on, it is used to emit light toward the second region Z2' to provide illumination behind the screen 40.
It should be noted that, when the use environment of the screen 40 is dark, if the illumination is provided only in the first region Z1' so that the brightness difference between the front and the rear of the screen 40 is relatively large, the stimulation to the human eyes is too large, and the eyes are easily fatigued. Compared with the case of providing illumination only in the first zone Z1 ', the first light source 100 of the clip light 30 emits light in the first zone Z1 ' and the second light source 200 of the clip body emits light in the second zone Z2 ' at the same time, so as to reduce the brightness difference between the front and the back of the screen 40, and alleviate the discomfort of human eyes to the high brightness and dark contrast.
In addition, the first light source 100 is designed to be positioned above the upper surface of the screen 40 in order to provide illumination of the main reading area (i.e., the first area Z1') and to avoid obscuring the display of the screen 40. However, the second light source 200 is used to supplement light in the rear area of the screen 40 (i.e., the second area Z2') to reduce the brightness difference, so the height of the second light source 200 is designed to be below the upper surface of the screen 40. In response to the first light source 100 being used in a reading environment with a higher brightness requirement, the light intensity of the first light source 100 may be set to be higher than the light intensity of the second light source 200, and the two are in a ratio relationship. That is, the illuminance value of the first zone Z1 'is higher than the illuminance value of the second zone Z2'.
In one embodiment, the sensing directions L2 and L2 'of the first photo sensor 101 may be opposite to the irradiation directions L1 and L1' of the first illumination light, and the sensing directions L4 and L4 'of the second photo sensor 201 may be the same as the irradiation directions L3 and L3' of the second illumination light.
Specifically, as shown in fig. 4, when the lighting apparatus is the desk lamp 20, the irradiation direction L1 of the first illumination light is directed toward the lamp holder 210, and the sensing direction L2 of the first light sensor 101 disposed on the lamp housing 320 is opposite to the irradiation direction L1 of the first illumination light; as shown in fig. 5, when the lighting apparatus is the clip light 30 of the screen 40, the irradiation direction L1 ' of the first illumination light is irradiated toward the front surface of the screen 40, and the sensing direction L2 ' of the first light sensor 101 is opposite to the irradiation direction L1 ' of the first illumination light, wherein when the lighting apparatus is the clip light 30, the first light sensor 101 can be independent of the clip body and the first light source 100, and the user can place the first light sensor 101 or other structures including the first light sensor 101 on the desktop on which the screen 40 is mounted, or the first light sensor 101 can be disposed in other manners as long as it is ensured that it can sense the ambient light brightness and the brightness of the screen 40, which is not limited in the present invention.
In an embodiment, the first light source 100 and the second light source 200 can operate independently, and a user can independently turn on the first light source 100 or independently turn on the second light source 200 through the cooperation of hardware and/or software, for example, through the key and the button control processing module 300, so as to provide more usage scenarios and improve user experience. For example, when the first light source 100 is independently turned on, the processing module 300 controls the first light source 100 to provide the first illumination light according to the ambient light brightness of the first areas Z1 and Z1 ' to provide illumination for the first areas Z1 and Z1 ', and when the second light source 200 is independently turned on, the processing module 300 controls the second light source 200 to provide the second illumination light according to the ambient light brightness of the second light source 200 to provide supplementary illumination for the second areas Z2 and Z2 '.
In addition, as shown in fig. 6, fig. 6 is a schematic flow chart of the illumination structure provided by the embodiment of the present invention. Based on the lighting structure 10, the present invention further provides a method for controlling the lighting structure 10, which is applied to the lighting structure 10, and the method includes:
step S100, energizing the lighting structure 10, i.e. turning on the lighting structure 10;
in step S100, the user may manually turn on the lighting structure 10 by pressing a key or the like, or may turn on the lighting structure 10 by a wireless method such as voice wake-up and remote control, which is not limited in the present invention.
Step S200, the first photo sensor 101 senses the illumination brightness of the first areas Z1, Z1 ', and the processing module 300 turns on the first light source 100 and controls the illumination parameter of the first light source 100 according to the illumination brightness of the first areas Z1, Z1';
in step S200, the processing module 300 flexibly adjusts the illumination provided by the first light source 100 according to the ambient light intensity of the first areas Z1 and Z1', and preferably, when the lighting structure 10 is applied to the screen 40 clipping lamp 30, the first light sensor 101 can also sense the light of the screen 40 and the reflected light of the desktop on which the screen 40 is placed.
Step S300, the first photo sensor 101 senses the illumination brightness of the first areas Z1, Z1 ', and the processing module 300 adjusts the illumination parameter of the first light source 100 according to the illumination brightness of the first areas Z1, Z1';
in step S300, after the first light source 100 is turned on, the first light sensor 101 senses the illuminance values (and/or the ambient light brightness) of the first zones Z1 and Z1 ', and the processing module 300 determines whether the illuminance values of the first zones Z1 and Z1' satisfy a predetermined threshold, for example, the predetermined threshold is about 500 lux, which is suitable for the recommended ambient brightness of the general screen 40 (or reading). If the predetermined threshold is not met, the processing module 300 may calculate the illumination parameter required by the first light source 100 again, so as to intelligently adjust the first light source 100 to provide the illumination parameter meeting the current environment.
Step S400, if the first light source 100 has met the predetermined threshold, the second light sensor 201 starts to sense the illumination brightness of the second zones Z2, Z2 ', and the processing module 300 turns on the second light source 200 and controls the illumination parameters of the second light source 200 according to the illumination brightness of the second zones Z2, Z2';
in step S400, the processing module 300 flexibly adjusts the illuminance provided by the second light source 200 according to the ambient light intensity of the second area Z2, Z2 ', preferably, the second light source 200 emits light toward the other side different from the user, for example, when the lighting device is the screen 40 clipping lamp 30, the second light source 200 emits light toward the second area Z2, Z2' facing the rear surface of the screen 40. The processing module 300 turns on the second light source 200 to emit light, so as to reduce the brightness difference at the front and the rear of the screen 40 and provide a light supplement effect. Specifically, the processing module 300 may control the illumination parameters of the second light source 200 such that the illuminance values of the second areas Z2 and Z2 'are about 1/3 of the illuminance values of the first areas Z1 and Z1', so as to design the human eyes not to be easily tired. For example, if the first zones Z1, Z1 'reach about 500 lux or so, the illuminance values of the second zones Z2, Z2' are controlled to about 170 lux or so.
In step S500, the second photo sensor 201 senses the illumination brightness of the second areas Z2 and Z2 ', and the processing module 300 adjusts the illumination parameters of the second light source 200 according to the illumination brightness of the first areas Z1 and Z2 ' and the illumination brightness of the second areas Z2 and Z2 '.
In step S500, after the second light source 200 is turned on, the second light sensor 201 senses the illuminance values (ambient light brightness) of the second areas Z2 and Z2 ' again, and the processing module 300 determines whether the illuminance values of the second areas Z2 and Z2 ' satisfy a predetermined threshold, for example, the illuminance values of the second areas Z2 and Z2 ' are always lower than the illuminance values of the first areas Z1 and Z1 ' and have a ratio relationship with the illuminance values of the first areas Z1 and Z1 ', for example, the predetermined threshold may be about 150 lux. If the predetermined threshold is not met, the illumination parameters required by the second light source 200 can be calculated again by the processing module 300, so as to intelligently adjust the second light source 200.
It is understood that, when the user independently controls the first light source 100, the processing module 300 only performs the steps S100, S200, and S300, and when the user independently controls the second light source 200, the processing module 300 only performs the steps S100, S400, and S500, which are not described herein.
In summary, the illumination structure 10, the illumination apparatus using the same, and the control method of the illumination structure 10 provided by the present invention emit light through the first light source 100 facing the first areas Z1 and Z1 'and the second light source 200 facing the second areas Z2 and Z2', and the first light sensor 101 and the second light sensor 201 sense the illumination brightness of the first areas Z1, Z1 ', and the second areas Z2 and Z2', so that the processing module 300 adjusts the illumination parameters of the first light source 100 and the second light source 200 according to the illumination brightness of the first areas Z1, Z1 ', and the second areas Z2 and Z2', and the present invention can effectively improve the user experience and achieve the beneficial effect of eye protection.
