3. LED Lighting Principals What is LED Technology? LED Stands for Light Emitting Diode. It is a semiconductor device that emits light when a current is passed through it. LED technology is constantly evolving and found in a wide range of products in our everyday life. Typical applications over the years have been household appliances, telecommunications, signal technologies and indicator devices, more recently white LED’s have allowed the technology to become a very efficient modern light source. The development of White LED technology progresses at a rapid pace, the efficiency is constantly improving, quality of the light and colour of light also constantly improve. Consequently new applications for LED Lighting open up on a daily basis.

4. Types of LED Technology There are two major electrical components within a LED luminaire. • 1 LED Light Engine • 2 Driver LED Light Engines are available in a number of different packages, we use the following in our LED luminaires • 1 SMD LED Packages • SMD Stands for Surface Mounted Device, it is a very small LED package that is soldered and mounted directly to a PCB (Printed Circuit Board). This makes the technology ideal for edge lighting LED panels and for the LED Tubes. We utilise a large number of small LED’s to ensure uniformity of light, with no light hot (bright) spots. • 2 COB LED Packages • COB Stands for Chip On Board, these compact high flux density light sources deliver uniform high quality illumination without pixilation or the multiple shadow effect caused by LED component based solutions, enabling both diffused and directional lamp replacements for a wide range of applications.

5. LED Driver Types There are various types of LED Driver that we can use, the LED driver is used to control how the LED light source is operated. These are split into two main categories. • Fixed Output Drivers • These Drivers convert the incoming mains supply into the correct voltage and current for the LED array. They are “fixed” output which means they switch on and off only, without any dimming functionality. • Dimmable LED Drivers • Dimmable drivers are available to allow us to control and dim the LED light source, there are 4 main types of dimmable driver that a commonly used in the UK. • Triac – Leading edge or trailing Edge Rotary Dimmable (Traditional dimmer switch) • 1 -10V Analogue Dimmable, the dimmable signal is sent to the LED light fitting on a low voltage communication line. The signal if at 1V sets the dimming level at 10%, if at 5V the level is set at 50% and at 10V the level is set at 100% etc. • Switch Dim - The Dimming Level is controlled by a push to make switch on the switch live circuit. • DALI – Stands for Digital Addressable Lighting Interface, it is an addressable protocol that has been set out by a number of major manufacturers to allow compatibility of different manufacturers luminaires on a single DALI system. The advantage of an addressable lighting system is that each luminaire is given a unique address . These luminaires are then able to be monitored and controlled from a central source. Either Scene Select plates or computers.

6. Benefits of LED Lighting LED Lighting Systems provide significant savings, typically the energy reduction on a lighting circuit can exceed 50% LED lighting has an average life span of 50,000 hours with minimal Lumen Depreciation. This means the output of the LED does not deteriorate with time. Therefore giving a maintenance free lighting system and heavily reduced maintenance and re-lamping costs. LED Lighting provides instant full output light, unlike fluorescent and Discharge lighting that takes time to “warm” up to full light output LED Technology is not susceptible to switching cycles and does not deteriorate when switched constantly. This above two key points mean that the LED Lighting is the perfect technology to be used in conjunction with lighting controls.

8. Lighting Survey offer When we survey an existing lighting installation, we look at: What is the area used for? What is the Current Emergency Lighting System Is the work that we will carry out going to effect the current system? Age and condition of existing lighting? Type of luminaire? Wattage and type of lamps and control gear? Condition of the area clean/dirty? What is the clients main objective? Energy saving or increase in quality of Light?
