Let’s drive inside the LEDs
The two basic types of LEDs are indicator-type LEDs and illuminator-type LEDs. Indicator-type LEDs are generally cheaper, low-power LEDs only suitable for use as panel displays and indicator lights in electronic devices or as instrument lights in cars and computers.
It is a semiconductor chip (or matrix), a substrate that supports the matrix, contacts for power application, a binding wire for contact with the matrix, a heat sink, a lens and an outer casing.
Illuminator-type LEDs are durable, high-powered devices capable of providing illumination. All light-type LEDs share the same basic structure. It is a semiconductor chip (or matrix), a substrate that supports the matrix, contacts for power application, a binding wire for contact with the matrix, a heat sink, a lens and an outer casing.
Insides of LED Luminaire
To be used for lighting, LEDs must be integrated into fixtures that include lighting, LED drivers, power supplies, and heat management. Well-designed LED fixtures integrate all of these important components into one fixture.
Let’s see the advantages of LEDs
LED lighting offers a variety of benefits for professionals and end beneficiaries of LED lighting systems, from creative individuals to innovative companies and visionary cities and countries:
High-levels of brightness and intensity
LEDs produce high lumen output and guarantee the brightness of white and coloured light.
Colour, vibrant colours and regular white light LED lamps can create millions of colours or colour temperature ranges without the use of gels or filters.
LED lights are five times more energy efficient than incandescent and halogen light sources, reducing costs to reduce environmental impact.
Low-voltage and current requirements
LED lighting systems offer simple, flexible installation and use.
Low radiated heat
Since LEDs do not emit infrared rays, they can be placed sensitive to heat, close to people or objects, or in narrow spaces where it is dangerous to collect heat.
LEDs operate at low temperatures and can withstand shocks and vibrations, making them suitable for extreme environments and difficult areas for access. There is no moving part of the filament in the LED that can break or fail.
No UV rays or infrared radiation
LEDs do not emit harmful UV light that can erode materials or fade paints and pigments, making them ideal for use in retail stores, museums and galleries.
Long source life
LEDs provide significantly longer service life than traditional light sources, reducing maintenance and replacement difficulties.
LEDs can be controlled digitally (and automatically) for maximum efficiency and flexibility.
What these advantages indicates?
Over the past decade, LED technology has improved rapidly as demand has increased, and innovation has led to improved manufacturing methods and LED-related technologies. The once humble LED (used for indicator lights and other low-end applications) is now the light source of choice for high-profile and large-scale lighting projects. And today’s lighting professionals are exploring an extraordinary new frontier opened by LED lighting – and colour dynamics.
All colour dynamics lighting solutions are based on LED technology.
All colour dynamics lighting solutions are based on LED technology. Because, LED lighting solutions are highly efficient, durable, environmentally friendly and inherently controllable, enabling the implementation of incredibly creative lighting around the world. That’s why lighting professionals are using LED luminaires for a wide range of indoor and outdoor applications, taking advantage of the extraordinary flexibility of LED technology to explore new opportunities and achieve their creative vision.
How colour changing LEDs changes colour
An individual LED cannot change colour. Instead, a colour-changing LED consists of three separate LEDs in a housing operated by a microcontroller. The three LEDs are red, green and blue, so any one of these colours can appear at any time only one LED is going through a current. The passage of a current with two LEDs at the same time creates a combination of relevant colours, especially yellow, cyan or magenta. It is also possible to have different levels of current through different LEDs by creating shadows in six main colours. The passage of current at the same time with three LEDs creates a white light.
Uses of Colour Changing LEDs
Colour change LEDs can only be used for decorative effects, for example slowly cycling through different colours. These are also useful as indicators when a simple on / off screen is not enough, but space is limited. Google’s Nexus range of smartphones have a colour-changing LED that you can customize to display different colours for different alerts (such as email, text messages, or social media updates) using dedicated apps.
What LED lighting invention has brought for us
From tunable white to vibrant colours, colour kinetic LED luminaires now illuminate the world’s buildings, bridges and other iconic landmarks, as well as retail stores, television studios, theater and concert stages, hotels, casinos, hospitals, restaurants, nightclubs and celebrities.
