LED, which stands for light emitting diode, is a technology used in scores of products and is well-known for its use in specialty IT and audiovisual equipment as well as everyday products such as light bulbs. LED displays are used in a wide variety of ways and their popularity is exploding. But note that home flat screen televisions, often described as LED’s, are actually LCD (Liquid Crystal Display) televisions with LED back lights. Large format LED displays (video walls) are made up of modular tiles which are locked together so that they are seamless. They are extremely versatile:

  • They can be any size.
  • They can be curved.
  • They can be flown.
  • They can be on stands.
  • They can be used indoors.
  • They can be used outdoors.

Because of their versatility, LED’s are extremely popular for these video walls. Whether they are used as a wall or as individual displays, they are seen at live events ranging from commencements to concerts to corporate meetings. Typically LED displays are specified as indoor or outdoor displays. Indoor models are generally higher in resolution but less bright. But keep in mind the resolution is not comparable to a flat screen television or projector since they are designed to be viewed from a distance.

Unlike LCD’s, outdoor LED displays can be seen even in the sunlight and they are weather resistant; the level of weather resistance is measured as an Ingress Protection (IP) number. LED displays are universal; they are used on stage, in stadiums, educational institutions, and corporations. Given the dramatic impact they make, LED displays are very cost effective for advertisers, entertainers, and exhibiters.

Lights

LED lights, like LED displays, are widely used for audiovisual effects and are used both indoors and outdoors. They range from small stand- alone lights to complex systems of multiple lights that perform multiple functions in multiple locations. LED lights can be used in numerous ways:

  • To highlight or pin spot an area.
  • To flood an entire wall of a façade or stage.
  • To create a light show.
  • To highlight a landmark or a work of art.

Because LED lights can change colors or create a scene, they are a cost effective way to transform a space. LED lights are used to set the mood for special social occasions such as weddings, bar mitzvahs or holiday parties and they are used to light up dance floors in trendy nightclubs. They are a “must have” for DJ’s.

LED lights help corporations brand their products and display their logos. They are often a critical component of marketing campaigns and can be customized for important clients. Compared to the neon signs of yesteryear, LED lighting is more energy efficient, is longer lasting, and is better for the environment. Plus, it is appreciably more reliable. Consequently, LED lighting has become the standard for signs and exhibits, providing unsurpassed colors and mixing to create all types of images.

LED lights or “drapes” can be triggered or controlled to change the brightness, the color, and the content. They can display built-in patterns and/or they can fade.  LED lights can be pre-programmed for an event, presentation or show whether it’s a rock performance or a theatrical play. It can be spectacular – or it can be calming and serene.

Your imagination is the only limit to what LED displays or LED lights can do for you. For help in assessing your needs for LED lighting, with rentals or installation, call Zeo Systems; let our experience guide you to the right LED solution(s) for you.

Flipped Classrooms: Wave of the Future.. or Present?

Lecture hall seats are often empty now as college and universities increase or initiate “flipped learning” or “inverted” classrooms.  In a flipped classroom what is normally done in class e.g. lectures and what is normally done as homework are switched or flipped. In a flipped classroom, students read materials or listen to audio and view video podcasts before coming to class.

Using capture systems and video conferencing, lectures and PowerPoint presentations are stored remotely in a “cloud” and made available online, generally through the Internet. Homework such as problem solving and essay writing is done in class with both professors and peers guiding the students.

Now scores of classrooms resemble corporate huddle rooms or medical and scientific labs. Class time is reserved for hands on learning, discussions in small groups and collaboration instead of note taking. Flipped classrooms provide an opportunity for students to ask questions and to apply what they learned in the online lecture. It also provides students with more time to use scientific equipment in class and to utilize healthcare simulation labs which prepare them for real life health problems and emergencies.

There are two aspects to the “flipped classroom:” online learning and classrooms with the audiovisual equipment to allow content sharing and analysis. Professors usually create their own video lectures.  Although it takes time and skill to do a video, it is becoming easier as manufacturers bring new equipment for video capture and dissemination to the market.  The equipment is becoming easier to use and numerous, affordable storage solutions are readily available. In addition to their own videos, videos by publishers, and professional use apps;  course materials are often posted to YouTube or managements systems like Blackboard.

Flipped Classroom Image2Retrofitting classrooms for the digital world is likewise becoming easier. There are products that make it possible to connect devices with different signals and connectors, multiple control options, and interactive flat screen devices and whiteboards.

Video podcasts or video courses are audiovisual files distributed via the Internet. They are not the sole source of instruction and differ from MOOCs or massive open online courses. MOOC’s such as those offered by MIT are often open to anyone not just enrolled students.

Because clouds based storage makes it easy to store and share information, many universities are members of consortiums such as Unizen which includes the University of Michigan, Indiana University, Colorado State University, Penn State, the University of Florida and others. They share lectures, lesson plans and research and make course materials and information available from the best minds in education, organizations and corporations. The authorships are noted.

The Open Cloud Consortium (OCC), which is one of many worldwide, operates a cloud to support scientific, medical and health care research; it members include the University of California (Berkeley),  Florida International University, Johns Hopkins, NASA,  international universities and organization such as AIST (National Institute of Advanced Industrial Science and Technology).  OCC, in turn, has joined Matter, a workspace in Chicago with all types of rooms and AV/IT resources. Matter is a partner with the American Medical Association, and shares the same goal: to bring entrepreneurs and physicians together to “collaborate and test new technologies, services and products.”  Research universities are among those that benefit the most from flipped classrooms.

Technology, used effectively, is not a mindless way to teach but a way to open minds and to create paths to success. When flipped classrooms are introduced, both professors and students are often skeptical but not for long. They often flip their opinions on flipped classrooms once they have experienced the positive results:  grades and attendance go up, retention increases, team skills improve and applications of the course materials are discussed, analyzed and demonstrated.

Zeo Systems expertly trained technicians can assist you in determining the equipment you need to adjust today’s classroom to today’s technology. Flat panel displays, video and projection systems, microphone and voice systems, or complete control systems; No matter if we are integrating new technology to an existing system or building a new one from scratch, you can count on Zeo Systems to help you capture or record lectures and to design the audiovisual systems needed for your institution to successfully implement flipped classrooms.
