Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a lamp control method includes step S100, step S200, and step S300.
Step S100, ambient temperature data and ambient brightness data are acquired.
Specifically, the environment temperature data is the real-time temperature of the lighting environment where the lamp is located, and the environment brightness data is the real-time brightness of the lighting environment where the lamp is located. The environment brightness data are collected through a brightness collector arranged in the lighting environment where the lamp is located, and the collected environment temperature data are sent to the adjusting device to be analyzed in real time. The environment temperature collector collects the environment temperature data through the temperature collector arranged in the lighting environment of the lamp and sends the collected environment temperature data to the adjusting device for analysis in real time. It should be noted that the type of the temperature collector and the brightness collector is not exclusive, as long as the temperature and the brightness of the environment where the lamp is located can be accurately collected and sent to the adjusting device. For example, in one embodiment, the temperature collector is a temperature sensor and the brightness collector is a brightness sensor.
It can be understood that, in an embodiment, the temperature collector and the brightness collector do not work all the time, and only when the circuit where the lamp is located is turned on to turn on the lamp, the temperature collector and the brightness collector start corresponding temperature collection and brightness collection operations, which has the advantage of saving resources. In another embodiment, the collecting operation may be still performed when the circuit where the lamp is located is not turned on, so that the adjusting device can obtain accurate ambient temperature data and ambient brightness data in time after the lamp is powered on.
And S200, controlling the lamp to work at the corresponding lamplight brightness according to the environment brightness data.
Specifically, the brightness of the light is the intensity of the light emitted by the lamp, and for people to see the surrounding environment clearly, the required brightness of the light is also inconsistent in different ambient brightness. For example, in the daytime, the lamp is not needed to illuminate, and the brightness of the lamp light needed at this time is 0, while at night, the lamp is needed to emit a certain amount of light to illuminate, and the brightness of the lamp light is greater than 0.
And step S300, adjusting the corresponding lamplight tone output by the lamp according to the environment temperature data.
In particular, it has been found that the demand for light varies with the ambient temperature. Generally, people generally prefer to use a cool light source (i.e., white light) in seasons where the ambient temperature is high, such as summer, and generally prefer a warm light source (i.e., yellow light) in cold winter. Therefore, in the present embodiment, in order to provide a better environment for the user, the adjusting device will adaptively adjust the color tone of the light output by the light fixture according to the ambient temperature data after receiving the ambient temperature data. For example, when in winter, the ambient temperature is low, and the adjusting device controls the lamp to emit yellow light.
Referring to fig. 2, in one embodiment, step S200 includes step S210 and step S220.
And step S210, correspondingly reducing the lamp brightness of the lamp when the ambient brightness data is increased. Step S220, when the ambient brightness data decreases, the light brightness of the lamp is correspondingly increased.
Specifically, in this embodiment, the lamp brightness of the lamp is in a variable state as the ambient brightness data changes. When the ambient light becomes dark, namely the ambient brightness data is reduced, the light automatically increases the brightness; when the ambient light becomes bright, namely the ambient brightness data is increased, the light automatically reduces the brightness. It should be noted that the lamp brightness adjusting operation is not exclusive, and in one embodiment, the lamp brightness adjusting operation may be performed by controlling the magnitude of the current input to the lamp under the condition that the voltage is not changed, and the greater the current input to the lamp, the greater the lamp power, and the higher the lamp brightness of the corresponding lamp. In other embodiments, the lighting brightness may also be adjusted in other manners, for example, for a case that there are a plurality of lighting fixtures, the lighting brightness may be adjusted by controlling the number of lighting fixtures connected to the circuit, and the greater the number of lighting fixtures connected to the circuit, the brighter the corresponding lighting brightness.
In an embodiment, please refer to fig. 3 in combination, a specific connection manner of the adjusting device and the lamp is shown in the figure, a PWM1 signal is used to control a dimming terminal of the dimming driver, and the duty ratio of the PWM1 is adjusted to adjust the current of the LED lamp, so as to adjust the light brightness of the LED, where the larger the duty ratio of the PWM1 is, the larger the current flowing into the LED lamp is, and the larger the light brightness of the corresponding LED lamp is.
Referring to fig. 4, in one embodiment, step S300 includes step S310 and step S320.
In step S310, when the ambient temperature data decreases, the warm tone ratio of the light tone of the lamp is increased. And step S320, when the ambient temperature data is increased, increasing the cold tone ratio of the light tone of the lamp.
Specifically, in the embodiment, as the ambient temperature data changes, the light hue of the lamp is in a changeable state. When the ambient temperature data gradually decreases, the corresponding adjusting device will gradually adjust the light hue to the warmer hue, i.e. the time of appearance of the warm hue light is longer than the time of appearance of the cool hue light in the unit time. When the temperature data is gradually increased, the corresponding adjusting device can gradually adjust the light tone to the cold tone, namely the time of the cold tone light appearing is longer than the time of the warm tone light appearing in unit time. Particularly, when the environmental temperature data is less than a certain value, the adjusting device controls the lamps to emit warm-tone light within a unit; when the ambient temperature data is larger than another fixed value, the adjusting device controls the lamp to emit cold-tone light within each unit.
It is understood that in another embodiment, a plurality of temperature thresholds may be set, and when the environmental temperature data is at different temperature thresholds, the adjusting device outputs different levels of light color tone. For example, in one embodiment, four temperature thresholds are provided, with the first temperature threshold being less than the second temperature threshold, the second temperature threshold being less than the third temperature threshold, and the third temperature threshold being less than the fourth temperature threshold. When the temperature data is smaller than the first temperature threshold value, the adjusting device controls the lamp to emit warm color light (namely, no cool tone light at the moment); when the temperature data is between the first threshold value and the second threshold value, the adjusting device controls the lamp to emit warmer color light (namely, a small part of cool tone lamp light and a large part of warm tone lamp light are contained at the moment); when the temperature data is between the second threshold value and the third threshold value, the adjusting device controls the lamp to emit middle color light (namely, the cold color light and the warm color light respectively account for half); when the temperature data is between the third threshold and the fourth threshold, the adjusting device controls the lamp to emit cold color light (namely, a small part of warm color light and a large part of cold color light are contained at the moment); when the temperature data is larger than the fourth temperature threshold value, the adjusting device controls the lamp to emit cold color light (namely, no warm color light at the moment).
In one embodiment, the lamps include a warm-tone lamp and a cool-tone lamp, and the increasing of the warm-tone ratio of the light tone of the lamps is to increase the on-time ratio of the warm-tone lamp per unit time and to decrease the on-time ratio of the cool-tone lamp; the cold tone ratio for increasing the light tone of the lamp is to decrease the on-time ratio of the warm tone lamp in a unit time and to increase the on-time ratio of the cold tone lamp.
Specifically, please refer to fig. 3 in combination, in this embodiment, the lamp is specifically an LED lamp, the warm white LED array represents a warm tone lamp, the cold white LED array represents a cold tone lamp, two ends of the warm white LED array and the cold white LED array are respectively connected to a first output end and a second output end of a dimming driver in the adjusting device, and respectively implement on and off control of the lamp through a switch tube, a control end of the switch tube is connected to a single chip in the adjusting device, and the on and off of the two switch tubes are controlled through a signal output by the single chip. In this embodiment, the first switch tube and then the second switch tube are switch tubes of the same type, and in order to ensure that the warm-tone lamp is lit or only the cool-tone lamp is lit at the same time, a phase inverter is arranged between the control end of one of the switch tubes and the single chip microcomputer.
In order to realize color temperature adjustment, a cold white LED array and a warm white LED array with relatively close conducting voltage drops are connected in parallel to the output end of the dimming driver, and power switching tubes MOS1 (a first switching tube) and MOS2 (a second switching tube) are adopted to respectively control the on-off of the cold white LED array and the on-off of the warm white LED array. The PWM2 signal is connected with the grid of the MOS1 to realize the control of the conduction time of the warm white LED array, and the PWM2 obtains an inverted signal after passing through the inverter, and the PWM3 signal is connected with the grid of the MOS2 to control the conduction time of the cold white LED array. When PWM2 is high, PWM3 is low, so the warm white LED array is on and the cool white LED array is off, and vice versa. The duty ratio of the PWM2 is adjusted to adjust the on-time ratio of the warm white LED array and the cold white LED array in unit time, and the effect of changing the color temperature is realized by utilizing the persistence time of human eyes.
Referring to fig. 5, in an embodiment, after step S300, the method further includes step S400 and step S500.
And step S400, when the temperature data is less than or equal to the preset temperature, controlling the hot air heater to start to operate so as to increase the ambient temperature. And S500, controlling the hot air heater to stop working when the temperature data is greater than the preset temperature.
Specifically, the hot air heater is connected to the lamp control circuit of the embodiment, and the adjusting device can adjust the color tone and brightness of the lamp according to the ambient temperature data and the ambient brightness data, and can also adjust the temperature of the environment where the lamp is located according to the ambient temperature data, so that an environment with a proper temperature is provided for a user. It should be noted that the size of the ambient temperature data is not exclusive and can be set by the user according to the actual situation. When adjusting device opens hot air heater according to ambient temperature data and carries the warm braw and carry out the intensification to the environment, temperature collector can also carry out temperature acquisition to the environment in real time to send the ambient temperature data that the collection obtained to adjusting device and preset the temperature and carry out contrastive analysis, so that can in time stop the transport of warm braw when temperature rise is greater than preset the temperature.
It is understood that, in one embodiment, the same device may be used to implement the adjustment of the brightness and the color tone of the lamp and the control operation of turning on or off the hot air heater through the same controller. In another embodiment, different devices may be respectively used to control the lamp and the hot air blower, for example, a color and brightness adjuster is used to receive the ambient temperature data and the ambient brightness data, so as to adjust the light brightness and the light color of the lamp, another temperature adjuster is used to receive the ambient temperature data, and then the hot air blower is turned on or off according to the result of comparing the ambient temperature data with the preset temperature.
According to the lamp control method, the ambient brightness data and the ambient temperature data of the environment where the lamp is located can be collected, the lamp can be adjusted to work at corresponding brightness in a self-adaptive mode according to the ambient brightness data, and meanwhile the lamp is controlled to emit corresponding light tones according to the change of the ambient temperature, so that the lighting requirements of users in different temperature environments are met. By the scheme, the light brightness and the light tone can be adjusted in a self-adaptive mode according to the temperature and the brightness of the environment where the lamp is located, the basic lighting requirements of users can be met, the lighting environment which outputs different light tones along with different temperatures can be provided for the users, and the lighting reliability is high.

In one embodiment, the hue adjustment module 300 is further configured to increase the warm hue fraction of the light hue of the luminaire when the ambient temperature data decreases; when the ambient temperature data is increased, the cool tone ratio of the light tone of the lamp is increased.
Referring to fig. 7, in an embodiment, the lamp control apparatus further includes a temperature adjustment module 400. The temperature adjusting module 400 is used for controlling the hot air heater to start and operate when the temperature data is less than or equal to a preset temperature so as to increase the ambient temperature; and when the temperature data is greater than the preset temperature, controlling the hot air heater to stop working.
For specific limitations of the lamp control device, reference may be made to the above limitations of the lamp control method, which is not described herein again. All or part of the modules in the lamp control device can be realized by software, hardware and a combination thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
The lamp control device can collect the ambient brightness data and the ambient temperature data of the environment where the lamp is located, work with corresponding brightness according to the self-adaptive regulation lamp of the ambient brightness data, and control the lamp to emit corresponding light tones according to the change of the ambient temperature, so that the lighting requirements of users in different temperature environments are met.

Specifically, the environment temperature data is the real-time temperature of the lighting environment of the lamp 40, and the environment brightness data is the real-time brightness of the lighting environment of the lamp 40. The ambient brightness data is collected by the brightness collector 10 disposed in the lighting environment of the lamp 40, and the collected ambient temperature data is transmitted to the adjusting device 30 for analysis. The ambient temperature collector 20 collects ambient temperature data by the temperature collector 20 disposed in the lighting environment of the lamp 40, and sends the collected ambient temperature data to the adjusting device 30 for analysis. It should be noted that the types of the temperature collector 20 and the brightness collector 10 are not exclusive, as long as the temperature and the brightness of the environment where the lamp 40 is located can be accurately collected and transmitted to the adjusting device 30. For example, in one embodiment, temperature harvester 20 is a temperature sensor and brightness harvester 10 is a brightness sensor.
The brightness of the light is the intensity of the light emitted by the lamp, so that people can see the surrounding environment clearly, and the required brightness of the light is not consistent in different environment brightness. For example, in the daytime, the lamp 40 is not needed for illumination, and the brightness of the lamp light is 0, while in the night, the lamp 40 is needed to emit a certain amount of light for illumination, and the brightness of the lamp light is greater than 0.
Research shows that the light demand of people changes along with the change of the ambient temperature. Generally, people generally prefer to use a cool light source (i.e., white light) in seasons where the ambient temperature is high, such as summer, and generally prefer a warm light source (i.e., yellow light) in cold winter. Therefore, in the present embodiment, in order to provide a better environment for the user, the adjusting device 30 will adaptively adjust the color tone of the light output by the light fixture 40 according to the ambient temperature data after receiving the ambient temperature data.

Specifically, the color tone brightness adjuster 31 is used for receiving the ambient temperature data and the ambient brightness data, so that the light brightness and the light color tone of the lamp 40 are adjusted, the temperature adjuster 32 is used for receiving the ambient temperature data, and then the on-off control of the hot air heater is realized according to the result of comparison between the ambient temperature data and the preset temperature. As the ambient brightness data changes, the lamp brightness of the lamp 40 is also in a variable state. When the ambient light becomes dark, namely the ambient brightness data is reduced, the light automatically increases the brightness; when the ambient light becomes bright, namely the ambient brightness data is increased, the light automatically reduces the brightness. It should be noted that the lamp brightness adjusting operation is not exclusive, and in one embodiment, the lamp brightness adjusting operation can be performed by controlling the current input to the lamp 40 under the condition of constant voltage, and the larger the current input to the lamp 40 is, the higher the power of the lamp 40 is, and the higher the lamp brightness of the corresponding lamp 40 is.

As the ambient temperature data changes, the light hue of the lamp 40 is also in a variable state. When the ambient temperature data gradually decreases, the corresponding adjusting means 30 will gradually adjust the light hue to a warmer hue, i.e. the time during which warm-hue light occurs is longer than the time during which cool-hue light occurs per unit time. When the temperature data increases gradually, the corresponding adjusting device 30 will gradually adjust the light hue to the colder hue, i.e. the time of occurrence of the cold hue light is longer than the time of occurrence of the warm hue light per unit time. Particularly, when the ambient temperature data is less than a certain value, the adjusting device 30 will control the lamps 40 to emit warm-tone light within a unit; when the ambient temperature data is greater than another fixed value, the adjusting device 30 will control the light fixture 40 to emit cool light in between units.
