Description

Smart home lighting device that adjusts indoor light brightness through human pupil size

technical field

The utility model relates to an intelligent home lighting device, in particular to an intelligent home lighting device which adjusts the brightness of indoor light through the size of the pupil of a person.

Background technique

With the continuous development of science and technology, smart home systems are gradually entering the family, and consumer electronics products are also becoming more intelligent. At the same time, multimedia static image analysis and digital image processing technologies are becoming more and more mature. Through the above means, the shape and size of objects in photos can be accurately analyzed. The purpose of electrical appliances has been made possible. But in real life, people often encounter such a situation. When the lighting device is turned on suddenly in a dark environment, people's eyes often cannot adapt quickly, especially when the light is turned on at night, there will be glare problems. ; If other methods are used to adjust the brightness of the indoor light, it will be difficult to achieve the immediacy and accuracy required by the human eye.

Utility model content

The purpose of the utility model is to overcome the above-mentioned disadvantages, comprehensively develop the existing technology, and provide a smart home lighting device with reliable performance and convenient use that can adjust the brightness of indoor light through the size of the pupil.

In order to achieve the above object, the technical solution adopted by the utility model is: a smart home lighting device that adjusts the brightness of indoor lighting through the size of the pupil of a person, which is characterized in that an infrared imaging and photoelectric conversion module is connected with a digital image processing module. The image processing module is connected with the lighting system; the MPU&DSP dual-core microcontroller included in the digital image processing module is respectively connected with the program memory FLASH, the data memory RAM, the keyboard control module and the LCD display module.

The beneficial effects of the utility model are: the device uses infrared imaging and photoelectric conversion modules to obtain pupil images, and obtains corresponding indoor brightness requirements through digital image processing module analysis, and then transmits related brightness information to the lighting system to make it run. As long as the user is in the room, the device can identify and calculate the indoor brightness required by the current user, and automatically adjust the lighting device.

If the acquisition system cannot obtain the pupil image of the human eye when the user falls asleep, the light will be turned off. When the user wakes up in the middle of the night, the system recognizes that the user's pupils are very large, and will illuminate with very weak light to ensure that the user will not be dazzled by strong light when turning on the lights at night; when the user adapts to the light environment, the pupils Gradually shrink, the lighting brightness gradually increases until it reaches the normal indoor brightness and then stops. The utility model has the advantages of simple structure, reasonable design, outstanding humanity, reliable performance and safe use.

Detailed ways

Below in conjunction with accompanying drawing and preferred embodiment, the specific implementation mode, structure, feature provided according to the utility model are described in detail as follows:

Referring to Fig. 1, a smart home lighting device that adjusts the indoor lighting brightness through the size of the pupil, is characterized in that an infrared imaging and photoelectric conversion module is connected to a digital image processing module (in the dotted line box in the figure), and the digital image The processing module is connected with the lighting system; the MPU&DSP dual-core microcontroller included in the digital image processing module is respectively connected with the program memory FLASH, the data memory RAM, the keyboard control module and the LCD display module.

The working principle of the device is as follows: After the infrared imaging and photoelectric conversion module collects the human pupil image, it transmits the formed electrical signal data to the expansion system such as the dual-core microcontroller in the digital image processing module. Analyze the data to get the light intensity required by people for the indoor; at the same time, the microcontroller reads the current lighting status information from the lighting device, and after comparing the calculated lighting brightness with the actual lighting status, the microcontroller will Some lighting brightness information is transmitted to the lighting device for execution, thereby completing the adjustment function of the indoor lighting brightness. Among them, the FLASH in the microcontroller expansion system is used as a program memory, and the RAM is used as a data memory; the keyboard control module and the LCD display module are human-computer interaction interfaces, and the user can control the system through the keyboard to work in intelligent mode or in manual mode. mode, as well as some other advanced controls, the LCD display module can be used for users to read the current system working status and original status.

The above-mentioned detailed description of the smart home lighting device for adjusting the brightness of indoor light through the size of the pupil of a person with reference to the embodiment is illustrative rather than restrictive. Therefore, changes and modifications without departing from the general concept of the present utility model should be Within the protection scope of the utility model.
