LED artificial climate chamberIt is an intelligent experimental equipment that uses efficient LED light sources as lighting systems, which can accurately simulate multi factor conditions such as temperature, humidity, light intensity, and light cycle in natural environments. It is widely used in plant growth research, seed germination testing, insect feeding, microbial cultivation, drug stability testing, and agricultural science. Compared to traditional fluorescent or incandescent light sources, LED has the advantages of low energy consumption, low heat generation, long lifespan, and adjustable spectrum (such as red light 660nm, blue light 450nm, far red light 730nm, etc.), which can more accurately meet the specific light quality needs of different organisms.
This climate chamber usually consists of a high-precision temperature and humidity control system, multi-channel LED lighting module, microcomputer program controller, stainless steel inner liner, and circulating air duct. The temperature control range is generally 0-50 ℃ (some models can reach -10-60 ℃), with a fluctuation of ± 0.5 ℃; The humidity range is 20% to 95% RH, with an accuracy of ± 3% RH. The light intensity can be infinitely adjusted, reaching up to 20000 lux or more, and supports complex program settings such as circadian rhythm and gradient changes. The box adopts double-layer insulated glass doors and sealed structure, effectively reducing energy loss and external interference.
LED artificial climate chamberIts structural design takes into account stability, uniformity, and intelligence, and is mainly composed of the following core components:
1、 Box structure system
Shell and inner container
Shell: Cold rolled steel plate sprayed or made of stainless steel material, rust and corrosion resistant;
Inner liner: usually made of mirror finish stainless steel (such as SUS304), smooth and easy to clean, corrosion-resistant, and conducive to light reflection;
Insulation layer: high-density polyurethane foam material (thickness 50-100 mm), ensuring excellent insulation performance.
Sealed doors and observation windows
Double or triple layered insulated tempered glass doors with built-in anti condensation electric heating film (to prevent fogging during low temperature and high humidity);
Magnetic door seal ensures airtightness;
Built in lighting (independent of the main LED light source) for easy observation.
2、 Temperature and humidity control system
refrigeration system
Using compressor refrigeration (air-cooled or water-cooled), some small models use semiconductor (TEC) refrigeration;
Equipped with evaporator, condenser, expansion valve, drying filter, etc.
heating system
PTC ceramic heater or stainless steel electric heating tube, with fast response, no open flame, and long service life.
Humidification system
Ultrasonic humidification or electrode/electric steam humidification, supplied through a water tank;
Use deionized water or distilled water to prevent scaling.
dehumidification system
Refrigeration dehumidification (condensation through evaporator) or rotary dehumidification (high-D models);
Real time feedback from humidity sensors enables precise closed-loop control.
sensor
High precision PT100 temperature sensor and capacitive humidity sensor are arranged near the sample area to ensure measurement representativeness.
3、 LED lighting system (core feature)
LED light source module
Installed on the top or side wall of the box, it can be configured with:
White LED (full spectrum)
Monochrome LED (Red 660 nm, Blue 450 nm, Far Red 730 nm, UV, etc.)
Multi channel programmable combination light source
The adjustable range of light intensity is wide (usually 0-2000 μ mol/m ²/s or higher).
Heat dissipation and optical design
Aluminum substrate+cooling fan ensures long-term stable operation of LED;
Diffuser or reflector to improve lighting uniformity (>90%).
Photoperiod control
Supports 24-hour arbitrary programming (such as 16h light/8h dark), simulating natural circadian rhythms.
4、 Air circulation system
Centrifugal fan+air duct design: forced internal air circulation to ensure uniform distribution of insulation, humidity, and light;
Adjustable wind speed (some models): adapted to the sensitivity requirements of different samples to airflow (such as seedlings vs seeds).
5、 Control system and human-machine interface
Microcomputer controller
Adopting ARM or PLC core, supporting multi-stage program settings;
Control parameters: temperature, humidity, light intensity, light cycle, operating time, etc.
control panel
Color touch screen (5-10 inches), graphical interface;
Display real-time curves, historical data, and alarm information.
Data recording and communication
Built in storage (SD card or Flash);
Supports USB export RS485、Wi-Fi、 Ethernet, can be connected to laboratory LIMS or remote monitoring platform;
Compliant with GMP/GLP data integrity requirements (such as audit trails, electronic signatures).
6、 Safety and auxiliary devices
Alarm for over temperature/over humidity/sensor malfunction;
Independent over temperature protection relay (hardware level safety);
Power filtering and grounding protection;
Shelves and sample trays: Multi layer adjustable stainless steel brackets with strong load-bearing capacity;
Drainage outlet: easy to drain after cleaning;
