Introduction to LEDs’ Basics

By Scott Patterson Light bulbs are seemed everywhere, and there are more than 20 billion light bulbs around the world right now. On an average that for every one person, there would be three light bulbs. In the future, we can expect a replacement of all the current lightbulbs with those of LEDs. The reason for the occurrence of this replacement is due to the fact that LEDs’ efficacy is multiple times higher than those of incandescent light bulbs. LED is possible in reproduce the theoretical limit of the conversion from electricity to light set by physics. LEDinside will dedicate a large resource contributing to the information about the practical aspects of LEDs and their lighting designs. Before we go further, it is important for us to understand the concept of LED. This LEDinside Knowledge Kit’s main objective is to tell you all practical uses of LEDs. Here we will not trouble you with the technical terms such as GaInP, GaP, etc. We want to quickly and emphatically, tell you what is LED exactly. LED stands for light emitting diode, just by looking at the term, you can already know a thing or two about LED that it is a diode. A diode is a device conducts current in one direction but not on the other. This summarizes what LED can do. LEDinside will explore more on its electrical behavior in future. What we wants to take away from here is knowing that LED has a much higher forward voltage than normal diodes used in electronics. While a common diode like 1N4148 has a drop of approximate 0.7V, a LED may has a drop of 3.6V. The reason behind this difference in electrical characteristics is due to the fact LED is not made of silicon. However on other characteristics, LEDs are very similar to those of other diodes. Also from the words light and emitting you get to know a lot more about LED. All diodes emit some or a little bit of light. Looking at a integrated circuit or IC, and use a scanner to find which part of the circuit is emitting light or conducting current. IC engineers use this method to debug their IC designs. However, the amount of light emitted by ICs is very small. LEDs, on the other hand, are designed and optimized for this very purpose. This is also why LEDs have a much higher forward voltage. Normal diodes have been modified to minimize their forward voltage and optimize their reverse breakdown voltage. LEDs are designed to produce the most amount of the right color of light while consume the least power. Forward voltage here by itself does not contribute to the process. However, forward voltage does explain how much of the power LED dissipates as heat, which we will discuss more about the next time. Present day thinking can generally divide LEDs into two categories: those of small devices and of power devices. Small has become prevalently adapted starting in the 1970s. They come in various colors such as red, blue, green etc. They are the small T1 devices approximately 5 mm each. It is so prevalent that they are sold tens of billions in units each year. They are used in the manufacturing of cell phone backlights, elevator pushbuttons, light bulbs, road signage, and a lot more.  What is notable about these small devices is their power level, or their drive current. A typical red small LED has a drive current of 20 mA with a forward voltage of 2.2 V, it only 44 mW in power. (The efficacy is so low that this is generally equal to the heat dissipated.) Small white LEDs have a higher forward voltage of 3.6V corresponding to 72mW and some small LEDs can be run to 100mA. Generally, these types of LEDs are used as indicators and not for lighting purpose. It takes about 14 of these LEDs to make a 1 W flashlight and at least hundreds of them to make a dim florescent replacement. Our focus here is on power devices. Power device are usually from 1 to 3 W and run at 350 mA. Their actual semiconductor part of LED as opposed to its package, the dice is significant larger than those of small LEDs, but it is not necessary for their footprint to be. These devices are commonly used in lighting than as indicators. Applications are vast such as flashlights, incandescent light bulb replacements, screen backlights, projector lights, headlights, and gradually penetrate through every known lighting use. White LEDs and color LED are very similar with only one obvious difference being the difference between forward voltages. The reason for this difference in forward voltages is due to the difference in the semiconductor material used to generate various color of lights such as red, yellow and blue. Furthermore, white light cannot be manufacture using one single material or not yet an engineered material been created to produce white light. If you have experienced with a prism, you would know that white light consists of various different colors. Thus, white light can be recreate using two general methods, one being using phosphor to convert blue light into white light, and the other being the combination of different color LEDs. The phosphor method is the most common. A typical wavelength of a blue light generated by LEDs is around 435 nm. Using blue light is the optimum choice because blue light can be absorbed by phosphor and reemitted as a broad spectrum of light approximating white light. Through this process light coming out from the phosphor will be lower than the energy when entering phosphor. Those disappeared energy is dissipated in a form of heat. In order to generated all the colors we, human can see in the spectrum, light entering has to be of higher energy that also means having a shorter wavelength, shorter than the color with highest energy here. For humans, the visible wavelengths is around 400 to 700 nm, and at 435 nm, the blue LED is the most energy efficient choice in generating white light using the phosphor method.

LED Lights to Create and Set Ambiance

By Tim Lenahan LED lights are starting to replace lights used in places like salons, amusement parks, and even courthouses. LED lighting is a major trend either in households or for architectural purposes. Some of the most prevalent decorative lightings include street bulbs, light strips, rope lights, floor lights and spotlights. Of course you will soon have a string of Christmas LED light lying somewhere in your house. People who are thinking of becoming a house owner, it is important for them to decide the details of the house they want from a enormous pool of choices because soon even the smallest detail of their living space is going to have an impact on their life. Unless one has passed through the estate agent, the banking institutions and a load of legal paper, one can start to imagine about its interior design if they have a specific taste how the inside of their house should look. Personalization of the interior illumination using LED lamps is a fantastic idea, it is highly recommended but neither necessary for new house owner to hire a technician to make specific request and fine-tune the ambiance of interior lighting in general. Often one feature that new house owner go beyond than what is necessary is the brightness of lights within each and every of the rooms inside their home. It is true that not all rooms are for the exact purpose and most of them require various intensities of lighting. The brightness set the mood for a specific room will unquestionably affect one’s feeling as well as its functionality. With LED lights installed into every perfect location, they will produce a comfort home environment with ease, and with stability that all of us can anticipate every day. The large pool of various choices of LED light bulbs was created to greatly reduce the electricity and energy wasted in form of heat release on to our planet every second. LED light bulbs are now a symbol for unveiling our physical and emotional wellbeing as being an eco-friendly person with sense of awareness. With the brief overview on these essential features on the LED light fixtures, it is certain that these light bulbs take parts in shaping our life, impact on our temper, mood and state of mind. For example area in your residence that is not well-lit, would typically received negative feedbacks like the room being gloomy and hazardous, with the same can go for extremely bright, over-lit places, creating a visually unpleasant even embarrassing experience. Light have been acknowledged as an element we employ to vision the surrounding we see and around us. The light are responsible for stimulate the cellular material that are at the back of our eyeballs, and for this reason, we can associate light with a detrimental or positive aspects of our past experience. The retina then delivers electric pulses that are sent through the brain and transported to the optic nerve. The process of visual processing is what allows us to feel and vision the environment surround us. It is no trick, light settings have been proven through studies to affect aspect of our bodies and our experience in an environment and our moods. Depends on your preference and functionality of each rooms and areas, one should determine the correct lighting fixture that is going to provide the maximum comfort.

As stated above, it is suggested to avoid top glowing lighting because it could generate physical distress as well as visual tension for some people. Moreover, lights that are too low in intensities should also be avoid due to its potential of causing gloomy feelings and could lead up to lowering of physical activities. Due to the psychological effects that various brightness of light can have on its residents, it is important for the house owner to make a proper choice in each every area of their household. LED lights are recommended for house owners for the reasons of precisely positive feeling and a proficient lifestyle, now you can have this feeling in you possession, the sense of well-being in your household. LED lights have been applied in various commercial spaces, including restaurants, retail stores, museums, amusement parks. These lights have been test to satisfy finicky customers and designers, as they apply LED lighting to enhance the look of their interior design, set the ambiance of an environment, light merchandises and complement art works. Lighting for the commercial sector is a good business niche, it also helps companies to grow, commercial customer have to think about initial costs and longer term payback when installing light fixtures, at an initial price that will discourage noncommercial customers. For example at retails stores, managers have to decide exceptionally good lighting system to create a welcoming ambiance to lure in people to their shops. LED conversion could not be taken place in a better time, for that the nation is experiencing quite a financial crisis with the debt crises going on in Europe. Any form of help that are going to lessen the utility bills will be encouraged. LED is perfect for the task of saving national lighting electricity bill. LEDs are extremely efficient. The luminous functionality of LED is approximately 70 to 100 lumens per watt. In comparison, incandescent light bulbs’ luminous functionality is merely 8 to 15 lumens per watt. Therefore, LEDs are more energy efficient, unlike incandescent light bulbs release a large portion of its energy in a form of heat wasted. LEDs are eco-friendly because they do not incorporate mercury or lead in its manufacturing process and they do not emit UV rays and infrared. LED use a low voltage to operate and release very little heat so they are cool enough to touch. LEDs also run quietly and can be dimmed effortlessly. The most advantageous versatility of LED lights is their design flexibility. LEDs come in various different sizes and colors, and due to its small in size, you can create any shape and clusters of light using a designated numbers of them. LEDs are available in a majority of warm white, white, red, blue, yellow and more. LEDs can be modified to emit specified color tone and brightness. There are merits about LEDs that Designers can easily take advantage of. For example at the Ripley's Mirror Maze attraction, 100 mirrors were designed with digital sound and LEDs in order to build a mind blowing maze. Take place in El Paso, Texas recreation center, this maze is about 2,000 square feet big and includes dead ends and continuing loops. The mirrored trails are incorporated with sound effects to enrich the maze with more dimension and surprises. The use of LED light as a treatment program has been implemented by many surgeons. Also a great deals of Salons have made use of LED lights as a treatment, the practical uses of LEDs are becoming versatile and prevalent. Furthermore, A wall surface inside of the new federal courthouse designed by Antoine Predock, had been instilled with LED lights to create a light displays that pass from shades of orange to baby pink, to red and white and finally dazzling with blue lights. The design is explained as a simulation of the West Texan desert sky. This new project titled SKY is designed by a New York based artist Leo Villareal. The design and lighting sequence is entirely set by complex computer calculation.
