Description

Technical Field

[0001] The present invention relates to the field of intelligent lighting technology, and in particular to a constant illumination human-factor intelligent lighting terminal. Background Art

[0002] For large indoor lighting places, such as warehouses or factories, a large number of lighting equipment are usually installed to match the control method of manual wall panel switches. For areas with high illumination requirements on the work surface, after the lamps are turned on, regardless of the brightness of the ambient light in the lighting area and whether there are people, the lighting fixtures are always in a constant state, causing energy waste. At the same time, the light attenuation of the lighting fixtures for a long time is serious, which greatly reduces the service life and lighting effect of the lamps. At present, infrared or sound sensors are used in the corridor area of ​​indoor spaces to sense the entry and exit of people. When someone enters, the lighting equipment is automatically turned off after a certain period of time, thereby achieving energy saving. Sensors that sense ambient light illumination are also used in lighting equipment. When the light environment sensor senses that the illumination is lower than the set value, the lighting equipment is automatically turned on and the lighting equipment is always in the lighting state. When the illumination is higher than the set value, the lighting equipment is automatically turned off, thereby achieving energy saving. For the lighting equipment of the overall environment, the lighting equipment is not adjusted synchronously due to the long-term presence of personnel or slight body movements, or changes in the surrounding natural ambient light, so as to achieve the effect of constant surface illumination in the target working area. In addition, if the central control platform system is used, network layout costs, energy consumption and control difficulty will be derived.

[0003] In addition, lighting equipment that uses traditional light sources has large light flicker, and lighting equipment that uses ordinary LED lamps has problems with light flicker and high blue light content. Working or living in this light environment for a long time can easily cause visual fatigue, retinal damage, and decreased vision to the human eye.

[0004] With the development of social economy, energy conservation and emission reduction, and the deepening of the concept of light health, the green lighting upgrade of lighting equipment in indoor lighting places has become an inevitable trend. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a constant illumination human-factor intelligent lighting terminal with the characteristics of no flicker, low blue light and energy saving. When there are people in the indoor light environment, the brightness of the lighting terminal can be adjusted in real time according to the changes in ambient light, so as to control the illumination of the indoor space within a reasonable range, and ensure that the illumination of the area illuminated by the human-factor intelligent lighting terminal is constant at a set value, so as to achieve a constant illumination level on the surface of a fixed position.

[0006] The technical solution of the present invention is:

[0007] A constant illumination human-factor intelligent lighting terminal, comprising: a human presence / micro-motion sensing module, a light illumination detection module, a communication module, a control module, a lighting module and a data storage module;

[0008] in,

[0009] The microwave human presence / micro-motion sensing module is installed on the surface of the human-factor intelligent lighting terminal, facing directly below the indoor space. The microwave human presence / micro-motion sensing module is used to sense whether there is a person directly below the human-factor intelligent lighting terminal and whether the person has body movements, and send the sensing result to the control module through the communication module in real time. The control module compares the data with the data in the data storage module, and outputs the comparison result to turn on or off the human-factor intelligent terminal;

[0010] The light intensity detection module is installed on the surface of the human-factor intelligent lighting terminal, facing directly below the indoor space. The light intensity detection module is used to detect the light intensity directly below the human-factor lighting terminal, and send the detected light intensity data to the control module through the communication module. The control module compares the data with the data in the data storage module, and outputs the comparison result to increase or decrease the brightness of the human-factor intelligent terminal lighting module;

[0011] The communication module is installed inside the human factor intelligent lighting terminal, and is used to send the data detected by the microwave human presence / sensing module and the data detected by the light intensity detection module to the control module;

[0012] The control module is installed inside the human factor intelligent lighting terminal, and is used to compare the data detected by the microwave human presence / micro-motion sensing module and the light intensity detection module sent by the communication module with the pre-set values ​​in the data storage module, and turn on, turn off, increase or decrease the power supply current of the lighting module according to the comparison result;

[0013] The lighting module is installed on the surface of the human factor intelligent lighting terminal, and is used to receive the lighting instruction from the control module and illuminate the area within its irradiation range, and provide a flicker-free, low-blue light lighting environment for the irradiation area;

[0014] The data storage module is used to store the lighting adjustment instruction information corresponding to the data set by the microwave human presence / micro-motion sensing module and the light intensity detection module, and provide the control module with real-time access.

[0015] Further,

[0016] The control module adopts the Boost+Flyback application structure and the two-level flicker-free solution to ensure the output current stability, so that the human-friendly intelligent lighting terminal can provide flicker-free ambient light.

[0017] Further,

[0018] The lighting module is used to receive lighting instructions from the control module to turn on, turn off, and increase or decrease the luminous flux output by the lighting terminal and illuminate the area within its illumination range.

[0019] The lighting module adopts LED light source, which is connected in series and parallel to form a module, and is used to receive lighting instructions from the control module and illuminate the area within its irradiation range.

[0020] The LED light source of the lighting module adopts a purple light chip, which produces white light through phosphor. The blue light content in the 380-440nm band of the luminous spectrum is low, which can effectively reduce the damage to human eyes caused by lighting equipment.

[0021] Furthermore,

[0022] When the microwave human presence / micromotion sensing module detects that there is a person within a certain range below it and that the person is moving, or that there is a person and that there are micro-movements, the light intensity detection module of the human-caused intelligent lighting terminal starts to work and detects the ambient light intensity value around the human-caused intelligent lighting terminal. When the brightness value detected by the light intensity detection module is higher than the set value, the lighting module of the human-caused intelligent lighting terminal is kept in the off state; when the light intensity detection module detects that the light environment illumination is lower than the set value, the lighting module of the human-caused intelligent lighting terminal is turned on and the brightness output by the lighting module is adjusted according to the value of the ambient light brightness. The light intensity detection module compares the detected ambient light illumination with the set value again. When the ambient light illumination value has reached the set value of the light intensity detection module, the light intensity detection module feeds back the detected illumination value to the control module to maintain the existing power supply current, thereby achieving the state of constant illumination of the human-caused intelligent lighting. When the microwave human presence / micromotion sensing module detects that there is no one below the human-caused intelligent lighting terminal, the human-caused intelligent lighting terminal is in the off state, thereby achieving an extremely energy-saving state.

[0023] If the microwave human presence / micro-motion sensing module does not detect the presence of a person or micro-motion of a body, the lighting detection module will not start the detection and the controller will not issue a command to turn on the lighting module.

[0024] The microwave human presence / micro-motion sensing module transmits 5.8 GHz radio microwaves to the detection area, and receives radio waves reflected by all human movements and limb micro-motion targets in the area, which are converted into difference frequency electrical signals by the sensor's microwave circuit. Then, based on the linear frequency modulation continuous wave target modulation principle and processed by a high-performance digital signal recognition algorithm, it analyzes whether there are micro-motion targets and motion targets in the area.

[0025] The light intensity detection module measures the ambient light intensity based on the photosensitivity effect, and realizes the perception and measurement of the light environment by converting the external light environment illumination value into an electrical signal output.

[0026] The beneficial effects of the present invention are:

[0027] The present invention comprehensively identifies whether there is a person, whether there is a person's micro-movement, and the brightness of the surrounding environment, and intelligently adjusts the luminous flux output by the lighting terminal in real time to reach and maintain a preset illuminance value, thereby ensuring that the illuminance value remains constant when there is a person. The present invention is completely different from the existing implementation methods and improves the existing deficiencies, providing a constant illuminance human-factor intelligent lighting terminal and system that is both flicker-free, low in blue light, and energy-saving.
