LED stands for Light Emitting Diode.
A light-emitting diode is a semiconductor device that emits visible light when an electric current passes through it.
DIP (Dual In-line Package - where the method of manufacture is attaching the LEDs through a hole to the circuit board) is made up of three separate LEDs; a red, blue and green that when combined, make up the full colour spectrum. DIP LEDs are more common and cheaper to produce.
SMD (Surface Mounted Device - where the lights are mounted on the surface of the boards and the colours are combined into one light) LEDs are a newer technology. They are smaller, thinner and brighter thus giving a crisper picture and offering a wider viewing angle. Due to the built-in technology, SMD colours are more vivid and true.
An LED screen is made up of hundreds of tiny LEDs operated by a control box. A full colour screen with DIP LEDs are in clusters of red, green and blue diodes that light up accordingly to create the correct colour.
A full colour SMD screen is made up of hundreds of SMD diodes that emit the required colours depending on the information from the control box.
An LED TV is actually an ordinary LCD TV that is backlit using LEDs rather than a fluorescent tube. The correct name for these TVs would be LED backlit TV.
An LED screen is made up of hundreds of individual light emitting diodes (LEDs) that light up in sequence to form an image.
On an LED display, pixels are made up of one, or a cluster of LEDs with each pixel delivering a single point of light or colour. Pixels can be close together or far apart depending on the desired viewing distance. A higher resolution sign has a greater number of pixels per square metre.
The pitch of an LED display is the distance between the centre of two pixels. The smaller the pitch, the crisper and more realistic (ie: less pixelated) the image will be, especially when viewed from shorter distances.
People are more likely to read an LED sign over other forms of signage because they are conditioned to expect important information such as traffic conditions, flight and train schedules on LED signs.
Additionally, all LED signs are programmable meaning that you are not stuck a with static message, or the expense of changing your message once it is out of date.
Displays can be updated as often as required making an LED sign a one off investment that offers great flexibility.
No. LEDs consume substantially less power than fluorescent and incandescent light sources. LED technology is also highly reliable, long lasting and requires minimum maintenance. Additionally, LED sign content can be updated at the push of a button thereby eradicating the expense of having to replace out dated static signs.
A good quality LED sign or screen can run for up to 100,000 hours. However, it is important to understand that the 100,000 hour lifetime for an LED sign refers to the time it takes for an LED chip to reduce in brightness by 50%. LED signs do have long life spans, but for a chip to last 100,000 hours everything from the quality of the componentry, the drive current, assembly, ambient temperature and junction temperature needs to be faultless.
The junction temperature of an LED chip must be maintained at the level prescribed by the manufacturer. If the temperature rises by 10°C the LED chip will reduce to 50% brightness after 80,000 hours and if the junction temperature rises by 30°C, brightness will fall to 50% after just 12,000 hours.
Ambient temperature refers to the temperature in a room, or surrounding an object under discussion. In an LED sign the ambient temperature is the temperature within the cabinet and should be controlled using temperature sensing technology.
Junction temperature is the temperature at the point where an individual diode connects to its base. Maintaining the correct junction temperature is important to the longevity of an LED display.
M2 Signs provides a number of communication options (including remote keypad for indoor signs, GSM modem or wireless Bluetooth) and easy to use software systems so your sign can be simply and instantly updated either via a program accessed over the internet or on a computer located on your premises.
M2 Signs' range of outdoor displays have a IP65 rating and are fully waterproof, can withstand harsh temperatures and dusty environments and are designed with a brightness level suitable for reading in direct sunlight. Indoor signs incorporate brightness levels that suit indoor ambient light levels and closer viewing distances.
RGB stands for red, green, blue. An RGB screen is a full colour screen that uses various combinations of these three colours to create up to 16 million colours and shades.
This will depend on application but as a rough guide, halving the text height equates to the viewing distance in metres. For example 140mm text height is suitable for viewing to 70m. Indoor signs have a greater distance.
No. M2 Signs offer installation and commissioning for all signs. Additionally, M2 Signs' project management team custom design, engineer, assemble and test all our signs.
LED signs are very reliable, do not produce much heat and are long lasting. M2 Signs offers national service and manufactures its signs so they can be easily serviced should the need arise. All our LED signs have a 2 year warranty.
Our team can help you find the right sign to meet your requirements. Some of the things that you need to consider are;
• Viewing distance
• Type of images or text that you want to display
• Access for maintenance
• Will it be permanent or will it be put up and taken down
