Dimming model is widely used for sport field application and national stadium as the dimming energy saving and arena color change. By turning off the lights and adjusting the intensity, you can use the atmosphere to set the atmosphere and comfort of the venue and provide the audience with the opportunity to completely relax while watching the game.
This page will introduce what is dimming system in lighting and how to choose suitable dimming model for your sport field.
A dimmer is a device connected to a light fixture and used to reduce the brightness of light. By changing the voltage waveform applied to the lamp, the intensity of the light output can be reduced. There are different lighting control systems that work well with LED lighting. The most commonly used systems in professional LED lighting are DALI, 0-10V, 1-10V and DMX.
LED Stadium Lights offer simple dimmable solutions for stadium lighting. Different events may require different lighting, even within the same venue. Some events even need different lighting over the course of the event as it progresses from dusk to full nighttime. With dimming capable lights, the ability to adjust the lighting on the fly is possible. Not only does this help provide different end results with the same light, but can also help reduce energy costs by using less power when the lights are dimmed.
Several methods are available to dim lighting. These dimming methods are below three groups:
Dimming of control signal (analogue): 0-10V, 1-10V
Dimming of control signal (digital): DALI
Dimming of control signal (digital): DMX
With a 1-10 V dimming technique, a signal is transmitted between 1 V and 10 V. 10 V is the maximum amount (100%) and 1 V is the minimum amount (10%).
Transmits a signal between 0 and 10 V. The output of the lamp is scaled such that a voltage of 10 V provides 100% light output. And, 0 V provides the least light output.
Mecree 0-10v Dimmable system can supports 0-10V dimming signal perfectly. By remote control and receiver, you can wirelessly control the brightness of LED lights from 10% – 100% as you need, effectively energy savings. This product comes with a signal input line and output line, make wiring quick and easy, highly saving installation costs. One controller can simultaneously control multiple sets of LED lights. Remote support four-channel, can control four independent controllers, multiple LED lights. This is an economic model, it can be used for small stadium lighting.
Simple change-over from a legacy fluorescent system
Compatibility with a wide range of dimmer switches
The drawbacks of 0-10v dimming is that it is not suitable for installations where each light requires its individual dimming percentage. When multiple LED drivers are connected to the same dimmer, they all respond identically to the dimmers current setting. No addressing is possible, all connected LED-drivers react identical on a command from their controller.
1. High-end remote controller: The remote controller is User-friendly, intuitive operation and
2. Smoothing processing technology: The software use smoothing treatment technology, adjustment
is smooth and stable without hopping, jitter and blinking.
3. Group control: The remote controller can control four group lamps
4. Synchronization control: The remote controller can synchronization control a group of light
5. Adjust dimming: you can adjust the brightness.
6. Memory function: When the power outage, energized again the light remembers the power failure
lighting state before
7. Remote control is simple, beautiful, stylish, high-end and reliable, long service life.
DALI (Digital Addressable Lighting Interface)
These dimmer switches use digital protocols to send dimming control signals to the driver and connect to the power supply through separate wires. They do not directly control the energy delivered to the driver. DALI stands for Digital Addressable Lighting Interface. This is an international standard that defines how lighting equipment should communicate with control and steering systems. Each system consists of a controller and up to 64 lighting components (such as ballasts). Each of these components has a unique address. The controller can control these components because the DALI system can send and receive data. The brightness range of DALI is 0-100%. This dimming model can be for some professional sport fields.
• Open IEC standard (IEC 62386) and can be used by anyone.
• DALI has an active organisation and DALI is constantly improved and extended.
• Full digital control – group creation or individual control of fixtures.
• Bi-directional communication makes for easier commissioning and greater flexibility in control gear.
• Polarity independent two wire control.
• BUS based protocol.
• Standardised dimming curves – better compatibility between controllers and LED drivers
The DMX512 protocol was first developed by USITT to control dimmers from a console using a standard digital interface. DMX512 surpasses the simulation system, but it cannot completely replace the simulation system. DMX512’s simplicity, reliability, and flexibility quickly make it a financially viable protocol of choice, as evidenced by a growing array of control devices in addition to dimmers. DMX512 is still a new field of science, with all sorts of wonderful technologies emerging on a rule-based basis.
DMX also can be used for RGB or RGBW models. Red, Green and blue lights can be built into stadium fixtures. They are expensive but can bring a big dimension to shows and the overall fan experience.
• Standardised protocol (USITT DMX512-A) and based on RS-485.
• Made for colour dynamics, but also for sound & moving heads.
• Fast – suitable for highly dynamic light shows.
• One DMX universe can handle 512 individual addresses.
• Large distance possible between the controller and the last driver (up to 300 meters).
Addressing is advantage, one controller can control each lights or each pole individually but we need to write a program you want in the controller to realize the dimming way you want.
DMX system is also widely used in the sports field. For example, during the opening and closing ceremonies of the sports meeting, RGB lighting effect will be used to render the venue. At this time, DMX system needs to be fully controlled to present a gorgeous effect.
Moreover, it is only used for white light. According to the requirements of different competitions, DMX system can adjust the illuminance without changing the number of lamps, so as to make the competition lights in controllable illuminance requirements and control the output of electricity charges.
Mecree light are also applicable to the international DMX512 protocol which can meet the needs of various types of venues. Customers can also choose RDM mode to edit and customize various effects according to their own needs in practical application.
With the development of the society and the progress of science and technology, the needs of users have become more intelligent and simple. Therefore, Mecree also provides users with a intelligent system – WIFI controller. It has abandoned the traditional DMX console and put the control core in the mobile phone which is not only simpler and more intelligent, but also cost saving.
MECREE can provide the most commonly used systems in professional LED lighting are DALI, 0-10V, 1-10V and DMX. If you want the dimming model for your sport field project or other application, welcome to send inquiry to [email protected]
