Description

Light fixture with intelligent dimming function

The present invention relates to a luminaire, and more particularly to a luminaire with intelligent dimming function.

In order to be able to move in a low-light environment and complete various things, the luminaire is a necessity in every environment.

The existing luminaires are all activated by a switch, and directly control a illuminating unit (such as a light bulb or an LED module) on the illuminating device to illuminate the environment after starting. However, if the user activates the light when the eye is sleepy, or activates the light in the dark, the user may feel uncomfortable with the light emitted by the light emitting unit.

For example, when parents get up in the middle of the night to feed and start the luminaire, excessive glare will cause eye discomfort and may wake the child up. For example, when the elders get up in the middle of the night and start the lights in the middle of the night, the excessively glaring lights will make the elders unable to clearly see the front and risk falling.

In view of this, a dimmable luminaire has been proposed on the market, which allows the user to arbitrarily adjust the brightness of the illuminating unit according to actual needs. Specifically, the lamp is mainly a light-emitting diode (LED) as a light-emitting unit, and the pulse-width modulation (PWM) method is used to adjust the power-on time of the LED by using the characteristics of the LED. The purpose of adjusting the brightness is achieved.

However, the user must manually adjust the brightness of the lighting unit (ie, manually adjust the PWM) every time the lamp is turned on. The lamp cannot be automatically adjusted because it cannot know the user's needs in different environments. Therefore, this kind of luminaire is not intuitive in use, and there is room for improvement.

The main purpose of this creation is to provide a luminaire with intelligent dimming function, which can automatically select or adjust the parameters used when the illuminating unit is started according to the time when the luminaire is triggered.

In one embodiment, the illuminator with intelligent dimming function includes at least one switch unit, a dimming unit, a lighting unit, and a control unit electrically connected to each of the units. The switch unit is used to accept an external trigger. The control unit obtains a current time when the switch unit is triggered, and selects a corresponding dimming parameter according to the current time. Then, the control unit controls the dimming unit to control the lighting unit to emit light according to the selected dimming parameter.

Compared with the related art in the art, the creation can automatically select or adjust the parameters used when the lighting unit is started according to the time when the luminaire is triggered, thereby making the luminaire effective for any scene and time period.

For a more detailed understanding of the features and technical aspects of the present invention, reference should be made to the description and the accompanying drawings.

Please refer to FIG. 1 and FIG. 2, which are respectively a schematic diagram of a luminaire and a block diagram of a luminaire according to a first embodiment of the present invention. As shown in FIG. 1, the present invention discloses a luminaire with intelligent dimming function (hereinafter referred to as the luminaire 1), and the luminaire 1 is mainly connected to a mains 2 to receive power required for operation by the mains 2. Moreover, the lamp 1 is provided with a switch unit 11 for accepting a trigger from the outside of the user, thereby controlling the start and stop of the lamp 1.

In an embodiment, the luminaire 1 can be connected to the Internet of Things 3, and is connected by the Internet of Things 3 to other electronic devices (such as smart TVs, smart refrigerators, smart air conditioners, etc.) that are also connected to the Internet of Things 3 in the environment. communication. Moreover, since the luminaire 1 can be connected to the Internet of Things 3, the current time can be directly learned by the Internet of Things 3, thereby implementing an intelligent dimming function according to the current time (detailed in detail).

Referring to FIG. 2 , in the embodiment, the lamp 1 has the switch unit 11 , a control unit 12 , a power unit 13 , a network unit 14 , a memory unit 15 , a dimming unit 16 , and a lighting unit 17 . The control unit 12 is electrically connected to the switch unit 11, the power unit 13, the network unit 14, the memory unit 15, and the dimming unit 16, to integrate the units 11, 13-16. control.

The lamp 1 is connected to the mains 2 via the power supply unit 13 to receive power required for operation by the mains 2. Specifically, the lamp 1 can be powered after the power unit 13 is connected to the mains 2, and the network unit 14 can be started after the lamp 1 is powered on (when the lamp 1 can be turned on or off), and is activated. Automatically connect to the Internet of Things 3 afterwards.

The memory unit 15 pre-stores one or more dimming parameters 151. Specifically, the user may preset one or more of the dimming parameters 151 and store them in the memory unit 15. In an embodiment, the light emitting unit 17 can be a Light Emitting Diode (LED), and each of the dimming parameters 151 can respectively correspond to a different starting speed of the light emitting unit 17 (ie, from full dark to At least one of a bright speed), a brightness, and a color. Moreover, each of the dimming parameters 151 can also be corresponding to different time periods according to the setting of the user (detailed later).

The dimming unit 16 is electrically connected to the lighting unit 17, and the dimming unit 16 accepts a command issued by the control unit 12, thereby controlling the lighting unit 17 to emit bright light according to the content of the command. In an embodiment, the dimming unit 16 can be a Pulse Width Modulation (PWM) module for controlling the light-emitting unit 17 to turn on/off, and can control the light-emitting unit 17 to emit light. Brightness and color.

The switch unit 11 can be a push button switch, a dip switch, a touch switch, a voice control switch, a proximity sensing switch, etc., and is not limited. In this embodiment, the control unit 12 is obtained when the switch unit 11 receives an external trigger (such as the user operates the switch unit 11 to turn on the light fixture 1), and can be obtained through the Internet of Things 3 connected to the network unit 14. The current time, and the corresponding dimming parameter 151 is obtained according to the current time. Next, the control unit 12 controls the dimming unit 16 to cause the dimming unit 16 to control the lighting unit 17 to emit light according to the obtained dimming parameter 151.

As described in the foregoing, the dimming parameters 151 may correspond to different time periods, respectively. In an embodiment, the time period can be roughly divided into morning, noon, afternoon, evening, and the like. In another embodiment, the time period can be divided into AM00:01~AM02:00, AM02:01~AM04:00, ...PM10:01~AM00:00 according to the hour. However, the above is only an embodiment of the present creation, but is not limited to the above.

In an embodiment, the user can set a specific dimming parameter 151 for a period with special needs (for example, in the middle of the night), and the starting speed recorded by the dimming parameter 151 is slower than a normal starting of the lighting unit 17. The speed is such that the brightness recorded by the dimming parameter 151 is less than a normal brightness of the illumination unit 17. In this way, when the user activates the lamp 1 during the time period, a more comfortable environment can be obtained (that is, the light-emitting unit 17 is brightened at a slower speed, and the brightness is smaller than the maximum brightness that the light-emitting unit 17 can reach). .

For example, when the user activates the luminaire 1 during the day, the dimming unit 16 can directly control the illuminating unit 17 to be normally turned on (the illuminating unit is turned on according to the normal starting speed and adjusted to the normal brightness); When the lamp 1 is activated in the middle of the night, the dimming unit 16 controls the lighting unit 17 to be slowly turned on according to the dimming parameter 151, and only turns on half of the brightness.

Please refer to FIG. 3, which is a dimming flowchart of the first embodiment of the present invention. FIG. 3 further discloses an intelligent dimming method of the present invention (hereinafter referred to as the method), and the method is mainly applied to the lamp 1 shown in FIG. 2.

As shown in FIG. 3, the lamp 1 is connected to the mains 2 by the power supply unit 13, and is connected to the Internet of Things 3 by the network unit 14 after being powered on (step S10). Next, the lamp 1 continues to determine whether the switch unit 11 accepts an external trigger (step S12). If the switch unit 11 does not accept an external trigger (ie, the user does not intend to activate the light unit 17), the method returns to the step S12 to continuously determine whether the switch unit 11 is triggered.

If the switch unit 11 accepts an external trigger (for example, the button switch is pressed, the touch switch accepts the user's touch, or the voice switch receives the user's voice command, etc.), the lamp 1 is directed by the control unit 12 The Internet of Things 3 obtains the current time (step S14). The control unit 12 obtains the pre-stored dimming parameter 151 according to the current time, and then controls the illumination unit 17 to emit bright light according to the obtained dimming parameter 151 (via the dimming unit 16).

Specifically, in an embodiment, the user may set a dimming parameter 151 in advance (ie, set a starting speed, a brightness, and a color of the lighting unit 17), and make the dimming parameter 151 correspond to A specific time period (for example, midnight). After the step S14, the lamp 1 can determine whether the current time is within the specific time period by the control unit 12 (step S16), thereby determining how to control the lighting unit 17.

In the embodiment shown in FIG. 3, if the current time is not within the specific time period (ie, the corresponding dimming parameter 151 does not exist in the memory unit 15), the control unit 12 (via the dimming unit) 16) The light-emitting unit 17 is controlled to normally emit light (step S18), that is, the light-emitting unit 17 is activated to a normal brightness according to a normal starting speed.

If the control unit 12 determines that the current time is within the specific time period, the control unit 12 further acquires the dimming parameter 151 corresponding to the specific time period in the memory unit 15 (step S20), and again (via the dimming The unit 16) controls the light-emitting unit 17 to emit bright light according to the obtained dimming parameter 151 (step S22). In this embodiment, the dimming parameter 151 includes at least one of a starting speed, a brightness, and a color of the lighting unit 17, and the starting speed is slower than the normal starting speed, and the brightness is less than the normal brightness.

Please refer to FIG. 4, which is a dimming flowchart of the second embodiment of the present invention. Figure 4 discloses another embodiment of the method of the present invention and can be applied to the luminaire 1 as shown in Figure 2. The difference from the embodiment shown in FIG. 3 is that the lamp 1 in the embodiment may not set the specific time period mentioned above, but divide the twenty-four hours all day into a plurality of time periods, and set each time period separately. A corresponding dimming parameter 151.

As shown in FIG. 4, in the embodiment, the lamp 1 is connected to the Internet of Things 3 by the network unit 14 after power-on (step S30), and continuously determines whether the switch unit 11 accepts an external trigger (step S32). .

If the switch unit 11 accepts an external trigger, the control unit 12 obtains the current time through the Internet of Things 3 (step S34), and obtains the dimming parameter 151 of the corresponding time period from the memory unit 15 according to the current time ( Step S36). In an embodiment, the control unit 12 may query a pre-established form (not shown) according to the current time to determine which time period the current time is located (for example, the twenty-four hours may be divided into 00:01~ 03:00, 03:01~06:00, 06:01~09:00, 09:01~12:00, 12:01~15:00, 15:01~18:00, 18:01~21: 00, 21:01~00:00 and other eight time periods). And, the memory unit 15 is read according to the query result.

Finally, after the memory unit 15 is read and the dimming parameter 151 of the corresponding time period is obtained, the control unit 12 controls the dimming unit 16 to control the light-emitting unit 17 to emit light according to the obtained dimming parameter 151. (Step S38), thereby providing ambient lighting desired by the user.

In this embodiment, the user can set different starting speeds, the brightness, and at least one of the colors for different time periods. In an embodiment, the user can set a first dimming parameter for the daytime period, wherein the first dimming parameter is recorded, because the user is less affected by the light emitted by the lamp 1 during the daytime. The starting speed is equal to a normal starting speed of the lighting unit 17, and the brightness recorded by the first dimming parameter is equal to a normal brightness of the lighting unit 17.

Furthermore, since the user is more susceptible to the light emitted by the luminaire 1 at night, in an embodiment, the user can set a second dimming parameter for the night time period, wherein the second dimming parameter The starting speed of recording is slower than the normal starting speed of the lighting unit 17, and the brightness recorded by the second dimming parameter is equal to the normal brightness of the lighting unit 17.

Through various embodiments of the present invention, the user can set the luminaire 1 to control the illuminating unit 17 to start at different speeds and achieve different brightness at different time points, thereby reducing the luminaire 1 in different environments. Discomfort to the user's eyes.

The embodiment of Fig. 5 discloses another luminaire 1' which, compared to the first embodiment shown in Fig. 2, does not have the network unit 4 and is not connected to the internet of things 3.

As shown in FIG. 5, the lamp 1' has the same switch unit 11 as the lamp 1 shown in FIG. 2, the control unit 12, the power supply unit 13, the memory unit 15, the dimming unit 16, and the illumination. Unit 17, and the luminaire 1' further has a timing unit 18 electrically connected to the control unit 12.

Specifically, the timing unit 18 continues to calculate the time after the lamp 1' is energized, whereby the control unit 12 can obtain the current time described above by the timing unit 18 when the switch unit 11 accepts an external trigger. In this way, the luminaire 1 ′ can be connected to the aforementioned Internet of Things 3 and the current time can be obtained at any time, thereby realizing the creation of the illuminating unit 17 according to the current time in a low-power operation environment. Technical purpose of speed, brightness and color.
