control system

This is the "brain" of the intelligent lighting incubator, consisting of a microcomputer controller, sensor group, and human-computer interaction interface. The microcomputer controller is equipped with preset programs and intelligent algorithms. Operators can set parameters such as light intensity, light cycle (such as 12h light/12h darkness), target temperature, humidity threshold, etc. through the touch screen or button panel; The temperature sensor, light sensor, and humidity sensor (optional) inside the box will collect real-time environmental data and provide feedback to the controller. The controller will compare the collected data with the set parameters, and if there is a deviation, it will automatically send adjustment instructions to the execution module to achieve closed-loop precise control of the parameters. Some models also support networked remote control and data recording, which can store and export operational data in real time for easy experimental traceability and analysis.

Lighting system

The system is responsible for simulating natural lighting environments and meeting the photosynthetic needs of different experimental subjects. The core components are light source components and lighting adjustment modules. The light source usually uses LED lights, fluorescent lights, or halogen lights (LED lights have become mainstream due to their low energy consumption and adjustable spectrum). Different spectra (such as white light, red light, blue light combinations) can be configured according to experimental needs to adapt to the photoperiod requirements of different growth stages of plants; The lighting adjustment module controls the on/off time, lighting quantity or power of the light source through the controller, achieving precise adjustment of lighting intensity (generally ranging from 0-30000lx) and lighting cycle, such as simulating the light dark cycle of day night alternation or setting multi-stage variable intensity lighting program. Some devices also have optimized lighting uniformity design, which ensures consistent lighting intensity in different areas of the box through lamp group layout and reflector structure, avoiding differences in experimental sample growth.

Temperature Control System

The temperature control system is used to maintain stable temperature inside the box, including heating units, cooling units, and temperature balance modules. Stainless steel electric heating tubes are commonly used as heating units. When the temperature inside the box is lower than the set value, the controller activates the heating tubes to increase the temperature inside the box through heat conduction and air circulation; The refrigeration unit is based on the principle of compression refrigeration and consists of a compressor, condenser, evaporator, etc. When the temperature is higher than the set value, the compressor operates to transfer the heat inside the box to the outside, achieving cooling; The temperature balance module uses PID (proportional integral derivative) temperature control algorithm to accurately control the start and stop timing and power of heating and cooling, avoiding significant temperature fluctuations. The temperature control accuracy of most intelligent models can reach ± 0.5 ℃, and the temperature range covers -10 ℃ to 60 ℃, which can meet different experimental conditions such as low temperature, normal temperature, and high temperature.

circulatory system

The circulation system includes air circulation and humidity circulation (optional) to ensure the uniformity and stability of the environment inside the box. Air circulation is achieved through the built-in fan, which drives the air inside the box to flow through the heating/cooling unit, air duct, and equalizing plate, forming forced convection to evenly distribute the temperature and light (indirect effect) in various areas inside the box, preventing excessive local temperature/light differences from affecting the experimental samples; The humidity cycling system is achieved through built-in humidifiers and dehumidifiers (or ventilation dehumidification). Humidifiers often use ultrasonic atomization or electrode humidification to increase air humidity, while dehumidifiers use condensation or molecular sieve adsorption to reduce humidity. Combined with feedback from humidity sensors, the humidity inside the box is controlled within the range of 30% -95% RH, meeting the strict requirements for humidity in microbial cultivation, plant seedling growth, and other fields.

Auxiliary support system

To ensure the safe operation of the equipment and prevent damage to the experimental samples, the intelligent light incubator is equipped with multiple protection mechanisms. The over temperature protection device will automatically cut off the heating/cooling power supply and sound an alarm when the temperature inside the box exceeds the safety threshold; Overload protection can prevent the circuit from burning out due to excessive current; The door safety lock and power-off memory function, the former avoids the accidental opening of the door during the experiment, which may cause environmental loss of control, while the latter can automatically continue the previous operating program after power failure recovery, ensuring the continuity of the experiment; Some models are also equipped with ultraviolet sterilization modules, which can sterilize the box before and after the experiment, reducing the risk of bacterial contamination.

Overall, the intelligent lighting incubator controls key environmental factors such as light, temperature, and humidity within preset ranges through a closed-loop process of "sensor acquisition controller analysis actuator adjustment feedback correction", providing a stable and reproducible artificial simulation environment for experimental research in fields such as biology, agriculture, and environment.
