Intelligent Building Sun Shadow Experiment Instrument for Building Lighting

JTG-S6Intelligent Building Sun Shadow Experiment Instrument for Building Lighting

Built in motor, realizing automatic simulation of altitude angle and azimuth angle instead of manual adjustment

Can place building models and observe the shadow and lighting effects of the models

The study of sunlight is extremely important in architectural design and teaching. The height angle and azimuth angle of a building relative to the sun will haveDifferent lighting and energy-saving effects. The JTG-S6 intelligent building sunlight tester is a professional tester developed based on the above requirements. This testing instrument can be used to draw bar shadow maps and place scaled models of buildings on the instrument measurement platform. Through the model, the shadow changes of buildings at a certain time and place, indoor sunshine duration, sunshine area, and shading of sunshades can be directly observed. It can also be used to observe the relationship and mutual influence between building orientation and spacing.

This experimental instrument achieves fully automatic control compared to the traditional manual three parameter sunshine meter. The test parameters are set by the supporting software, and the built-in motor automatically locates accurately. Single point testing can be achieved by determining the solar altitude angle and azimuth angle through latitude, longitude, and time. It can also simulate dynamic testing of continuous changes in solar altitude angle and azimuth angle. JTG-S6 is equipped with an illuminance sensor that can automatically collect illuminance distribution and analyze lighting characteristics through software. At the same time, digital imaging technology can also be combined for video capture and analysis of building models.

Features:

Automatically simulate the solar altitude and azimuth angle of the location where the building model is located (relative to the test building model)

Can achieve experiments on bar shadow drawing and observation of building shadows

High precision, multi-stage reduction motor achieves high-resolution simulation of solar motion trajectory

The operating platform is equipped with adjustable card holes for easy fixation of experimental models and cameras

A high brightness LED parallel light source with a large aperture lens has a wider effective area covering the experimental model and a smaller deflection angle

Conduct experiments:

Draw a stick shadow diagram:

By controlling the software to set the geographical location and simulated date/time, the solar tracker will automatically adjust to the corresponding solar altitude angle and azimuth angle at that time, and form a rod shadow through parallel light sources. Compared to the manual three parameter solar tracker, this device has more flexible time settings and can select geographical locations. The addition of an electric device greatly improves experimental efficiency.

Architectural Sun Shadow Observation:

A scaled model of a building can be fixed on the testing console, with a diameter of 1000mm. It can hold building models with a scale between 1:20 and 1:10, and can view the sun shadow in a certain area or at a certain time. It can also be set as a dynamic trajectory that automatically changes continuously, allowing for intuitive viewing of the sun shadow changes during a certain period of time in a short period of time.

Recording the entire process of solar shadow changes through imaging:

The dynamic changes of the sun shadow can be recorded by installing video recording equipment, which will become one of the most important design materials for architectural design. It can compare the sun shadow changes of the same building at different times and in different geographical locations.

Record the changes in illumination inside the building model:

Real time recording of illuminance values can be achieved through illuminance probes installed inside the building model, and the measured illuminance indicators can be used to draw lighting curves or analyze the feasibility of lighting design.

Control and data processing software:

Equipped with measurement and control software, it has dual functions of driving and controlling altitude and azimuth motors, as well as multi-point illumination acquisition. The software can select the simulated address name from the list, automatically query and calculate the latitude, longitude, date, and time of the simulated area, and drive the motor to reach the desired elevation and azimuth positions.
