Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to a gesture control method, a lamp and a lighting system. Background Art

[0002] With the development of artificial intelligence technology, gesture recognition technology, as an emerging human-computer interaction technology, has been applied to more and more fields. Gesture recognition technology can free users from the constraints of physical input devices, and its unique advantages of non-contact and what you do is what you get bring great convenience to users.

[0003] Gesture recognition technology is also used in lamps. At present, the commonly used sensors on lamps are ordinary infrared presence sensors, which can only detect whether an object is moving. Therefore, lamps can only recognize the waving action, and then realize one of the functions of switching on or off or switching brightness or switching color temperature. The single function cannot meet the needs. In the control scheme that needs to recognize multiple gestures, it is usually necessary to collect the user's hand image, determine the interaction command by identifying the gestures in the hand image, and then perform the corresponding operation. This requires adding an image sensor to the lamp, and image processing also requires a more complex controller, which is more expensive. Summary of the invention

Implementation

[0017] The method for controlling a lamp by using gestures, the lamp and the lighting system provided by the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Figure 1 A lamp 1 according to a preferred embodiment of the present invention is shown. The lamp 1 is a chandelier, and a distance sensor 101 is arranged on the lamp body. In other preferred embodiments, the lamp may also be a ceiling lamp, a wall lamp, a floor lamp, a table lamp, etc., which is not limited in the present application. A controller (not shown) is arranged inside the lamp body, and the controller receives the detection signal of the distance sensor 101 and controls the lamp according to the received detection signal.

[0019] In this embodiment, four control modes are provided to control the lamp 1, and each control mode corresponds to a gesture. When the user makes a corresponding gesture, the lamp 1 changes its working state, and the working state includes one of turning on, turning off, brightness change, color temperature change, and color change. Different gestures change different types of working states. Gestures and changed working states can be flexibly matched. The following briefly describes the gestures corresponding to the four control modes in this embodiment and the functions they achieve.

[0020] The first control mode is Figure 2As shown, the waving action realizes the switch of the lamp 1. When the hand is waved in front of the distance sensor 101, the hand passes in front of the distance sensor 101 in a certain trajectory, and the distance sensor 101 detects the object in a short period of time from the time when the hand enters its sensing range to the time when the hand leaves the sensing range. The time for a waving hand to pass in front of the distance sensor is greater than 0.1~2 seconds. As long as the time when the distance sensor 101 detects the object is recorded, the waving action can be identified. Therefore, we set it as a waving action when the time when the distance sensor 101 detects the object is greater than the first predetermined time and less than the second predetermined time. At the same time, in order to avoid misjudgment and ensure that it is a complete waving action, we also stipulate that the object will not be detected within the third predetermined time, that is, the hand will not return after waving, so as to avoid confusion with the stop action that is closer to the edge. The first predetermined time is 0.1~0.2 seconds, and it is 0.1 seconds in this embodiment; the second predetermined time is 1.5~2 seconds, and it is 2 seconds in this embodiment; the third predetermined time is 1~2 seconds, and it is 1 second in this embodiment. In this embodiment, when the time when the distance sensor 101 detects an object meets the above setting, the working state of the lamp 1 switches between on and off, and the currently on state becomes off, and the currently off state becomes on.

[0021] The second control mode is Figure 2 As shown, what is detected in this control mode is waving back and forth, that is, the hand passes in front of the distance sensor 101 in a certain trajectory, and then passes in front of the distance sensor 101 again in the opposite direction. The method for detecting a single waving is similar to the first control mode. When the time when the distance sensor 101 detects an object is greater than the first predetermined time and less than the second predetermined time, it is recorded as a waving. The value range of the first preset time and the second preset time is the same as the value range of the first control mode. In this embodiment, the specific values ​​are also the same, that is, the first preset time is 0.1 seconds and the second preset time is 2 seconds. Then, when the distance sensor 101 detects the object again within the preset interval time, and the time is greater than the first preset time and less than the second preset time, it is recorded as the second waving. The value range of the preset interval time is 0.3~2 seconds. It should be noted that the value of the preset interval time should be less than the third preset time, otherwise the lamp will directly perform the switch operation according to the first control mode, and the waving action back and forth cannot be recognized. In this embodiment, the interval time is 0.8 seconds. When the waving motion is recognized, the lamp 1 changes its working state, specifically, changes the application scene of the lamp 1. In order to meet the needs of various users, the lamp 1 has some preset working scenes, such as a working scene with cold white light and high brightness, a leisure scene with candlelight color, and a meeting scene with warm white light and a certain brightness. At the same time, the lamp 1 also provides the function of user-defined scenes, and users can set some scenes according to their preferences. When the waving motion is recognized, you can switch between different scenes.

[0022] The third control mode is Figure 4 As shown, this control mode recognizes a hovering gesture. When the distance sensor 101 detects an object for a time greater than the fourth preset time and the distance change is less than the first preset distance, it is considered that the user has made the gesture. The fourth preset time ranges from 1.5 to 2.5 seconds, and in this embodiment, it is 2 seconds; the first preset distance ranges from 2 to 4 cm, and in this embodiment, it is 3 cm. When the above conditions are met and it is recognized as a hovering gesture, the lamp 1 changes its color temperature. The change in color temperature is similar to the change in application scenario. The lamp 1 has several preset color temperatures, which change in sequence.

[0023] The fourth control mode is as follows Figure 5 As shown, the control mode recognizes the pulling action, that is, the hand is in front of the distance sensor 101, moving away from or approaching the lamp 1. When the distance sensor 101 detects that the change in the distance of the object within the fifth preset time is greater than the second preset distance, the action is confirmed. The fifth preset time value range is 0.4~0.8 seconds, and in this embodiment it is 0.5 seconds; the second preset distance value range is 3~10cm, and in this embodiment it is 3cm. When the above conditions are met, it is recognized as a pulling gesture, and the lamp 1 changes its brightness. As the hand moves from far to near, the lamp 1 becomes darker, and as the hand moves from near to far, the lamp 1 becomes brighter. Of course, in other embodiments, it may also become brighter from far to near, and darker from near to far.

[0024] In this embodiment, the lamp 1 simultaneously adopts the above four control modes to control the switch, scene, color temperature, and brightness respectively. In other preferred embodiments, only two or three of them may be used for control. Generally speaking, the waving action is easier to recognize and is also a more commonly used gesture. It is more suitable for switch operation, while controlling the brightness through the pulling gesture is more intuitive. These two combinations are more suitable in conventional lamps. Of course, waving back and forth and hovering actions can also be used to control the switch of the lamp, and this application does not limit this. However, in general, waving back and forth and hovering actions can be used as gestures for mode switching. Regardless of whether the application scene changes or the color temperature changes, one of the two can be used for control. When both need to be controlled at the same time, the gesture and the specific content of the control can be arbitrarily matched.

[0025] For gesture control, although it is contactless, we still require that the gesture action should be completed within a certain range in front of the distance sensor 101. This range is called the effective sensing distance. The effective sensing distance of the distance sensor 101 is not the distance it can actually measure, but the distance we set. Actions outside this range will not be recognized. This can effectively prevent people from walking or other non-control actions from falsely triggering the lamp 1. Only actions that enter the effective sensing distance of the distance sensor 101 will be recognized. The effective sensing distance of the distance sensor 101 is 0~50cm, and in this embodiment it is 20cm.

[0026] The above embodiment provides a gesture-controlled lamp, and another preferred embodiment may be a lighting system. The lighting system may include a plurality of lamps, a distance sensor, and a controller. The distance sensor may be provided on one of the lamps, or on a separate control device outside a lamp. The specific gesture control mode is similar to that in the lamp, and will not be described here. The controller controls each lamp according to the gesture command transmitted from the distance sensor.

[0027] The above description of the preferred embodiments of the present application is for illustration and description, and is not intended to be exhaustive or limited to the specific form disclosed. Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included in the scope of the present application defined by the attached claims.
