And turn on the lightning headlights, the lightning headlights draw two lightning bolts on the background. Let the audience seem to enter a virgin forest that is raining.
When the music time goes through the rain, the lighting scene changes automatically to the background. The brightness of the blue fluorescent lamp group gradually drops to 30%, the rain light, the cloud light and the lightning headlights automatically turn off, and the brightness of the white fluorescent light set gradually rises to 80% brightness, the white surface light, back light, and backlight of the animal specimen gradually rise to 50% brightness, and the color changer is automatically changed to white. Keep the audience in a fresh feeling after the rain.
When the music time is up to the night, the brightness of the white fluorescent lamp group gradually disappears, and the brightness of the blue daylight group gradually decreases to 10%. The white surface light, back light, and backlight of the animal specimen gradually drop to 20% brightness, and the water lamp is automatically activated. Let the audience experience the unique tranquility of the night in the virgin forest.
When the music time goes 
When going to the middle of the night, the brightness of the blue daylight group gradually decreased to 0%, the white surface light, back light, and backlight of the animal specimen gradually decreased to 0% brightness, and the brightness of the ground blue daylight group gradually increased to 20% brightness. The audience experienced the mystery in the virgin forest.
When the music time reaches dawn, the brightness of the blue daylight group gradually rises to 30%, the white surface light, backlight, and backlight of the animal specimen gradually rise to 30% brightness, and the brightness of the ground blue daylight group gradually disappears, the orange fluorescent lamp The brightness of the group is 60%, and the color changer is automatically changed to orange, allowing the audience to experience the vitality in the original forest.
The demo program can be cycled through a single button press. When there is no audience, the lighting scene automatically returns to the basic lighting scene, only a small number of basic lighting fixtures are turned on.
Third, the demonstration system solution 
The Museum of Species Diversity of Dalian Natural History Museum is a new exhibition hall in the museum. In the display means, it uses the high-tech of modern lighting, sound and multimedia computers. In addition to the traditional display, it also brings the specimens closer to the audience in an interactive way. The perfect combination of nature and people.
The types, functions and control methods of the lamps used are as follows:
The track dimmable downlight is used for backlighting and surface light of animal specimens. The PAR lamp is equipped with a color changer and is used as a backlight for animal specimens. The system hardware is controlled by HDL-MD1210 intelligent dimming box and HDL-MC48 IP-DMX performance controller (DMX512 signal output).
Fluorescent lamps (equipped with dimmable electronic ballasts) are used for sky changes, such as blue sky and sunset clouds; the system hardware is controlled by the HDL-MRDA06 digital dimming interface module.
Cloud lights, rain lights, strobe lights, and water lights are used to run the cloud, project the water, rain and lightning on the lake surface; the system hardware is controlled by HDL-MR 0610 intelligent switch module.

Fourth, the advantages of using HDL-BUS intelligent environment art lighting system
1. Colorful artistic effects.
A variety of lighting effects to achieve a variety of lighting control methods, can make the animal specimens in the museum have a variety of artistic effects, adding a lot of color to the animal specimens. Different colors of light give the museum vitality, making the whole scene more vivid and artistic, giving a rich visual effect and beauty. According to different time, different use, different effects, using the corresponding preset scenes for control, can achieve rich artistic effects.
2. Easy management and maintenance.
The intelligent lighting control system controls the lighting mainly with modular automatic control. The manual control is supplemented. The parameters of the lighting preset scene are stored digitally in the control panel. The setting and replacement of these information is very convenient, making the museum's Lighting management and equipment maintenance have become easier. At the same time, the entire demo program is also stored on the panel. When a visitor enters, the interpreter will simply turn off all the unwanted lighting scenes and enter a sound and photoelectric synchronized performance program with a single click.
3. Extend the life of the light source.
Extending the life of the light source not only saves a lot of money, but also greatly reduces the workload of replacing the luminaire, reduces the operating cost of the lighting system, and makes management and maintenance simple.
Whether it is a thermal radiation source or a gas discharge source, fluctuations in the grid voltage are a major cause of source damage. Therefore, effectively suppressing fluctuations in the grid voltage can extend the life of the light source.
4, good energy-saving effect Intelligent lighting control system with a variety of different "pre-set" control methods and control components, accurately set and manage the illuminance of different environments at different times to achieve energy savings. This method of automatically adjusting the illuminance only lights up or points to the required brightness when necessary, and uses the minimum energy to ensure the required illuminance level. The power saving effect is very obvious, generally up to 30%. In addition, the intelligent lighting control system performs dimming control on the fluorescent lamps in the hall. Since the fluorescent lamps adopt the dimmable electronic ballast with active filtering technology, the harmonic content is reduced, the power factor is improved, and the low voltage is reduced. Power loss.
