LED stands for Light Emitting Diode, and this light source should not be confused with a light fixture or luminaire. An LED is a component of the entire fixture. LED lighting can also be referred to as solid-state lighting (SSL) because an LED is solid-state technology similar to the memory in your computer. LEDs consists of four main parts.   LED Lights First Saw Automotive Use On Corvette Brake Lights. LED lights first saw automotive use on the Corvette, which was equipped with an LED center high mount stop lamp. Using LEDs in brake lights was (and is) a natural fit, since they illuminate seconds faster than an incandescent bulb does – giving drivers behind an earlier.

2) Fluorescent tubes sizes and LED tube light retrofitting Because fluorescent fixtures are often mounted into ceilings and connected directly to mains electricity, they are relatively expensive and difficult to replace completely. As a result, it oftentimes makes the most economical sense to simply use the same fluorescent fixture, but replace the fluorescent tube with an LED tube light. LED lamps are now rapidly replacing conventional incandescent lamps and compact fluorescent lamps (CFLs) in domestic and commercial lighting. Understanding the data that is presented with respect to lamp performance and operating life is the key to making informed product choices.

  Lighting is a basic, yet difficult-to-master, element of interior design, and Lighting Design Basics provides the information you need in a concise, highly visual format. Two leading designers, both with decades of experience, offer straightforward coverage of concepts and techniques, and present realistic goals you can use as guides to creating simple, typical lighting designs and when Reviews:   This book covers everything from the principles of portrait lighting (the nature of light, the equipment, light ratios, and classic lighting styles) to dozens of different practical applications of portrait lighting (business portraits, publicity headshots, high-key, one-light glamour, etc.).

LED lighting is all the rage these days. It’s energy efficient, long-lasting and available in a wide variety of innovative shapes. But the thing that matters most to people when shopping for LED lights and bulbs is the actual color quality of the light.

Anatomy of an LED strip. An LED strip light is typically half an inch ( mm) in width, and up to 16 feet (5 meters) or more in length.

They can be cut to specific lengths using just a pair of scissors along the cutlines, located every inches. In LED lighting, lumens measure the brightness of a light.

This is different than Watts, which measure the amount of energy in a light. The term lumen means “light,” which makes sense when you understand what this measures. In other words, lumens measure the amount of light your LED light.

A single light fixture stocked with a watt incandescent bulb consumes about kWh of electricity in a year; put a GeoBulb LED bulb in that light fixture, and the annual energy use is more like 65 kWh [source: Sundance].The annual CO 2 reduction is in the hundreds of pounds for a single lamp.

But energy-efficiency is just part of the story.

There are so many different types and variations that it can seem a little overwhelming at times. That’s why I wanted to write a quick post explaining the varieties, what makes them different, and things you should look for when choosing the LED driver(s) for your lighting application.

for evaluating LED fixtures and for making accurate comparisons to conventional fixtures. Describes how much ‘Useful Light’ a fixture can deliver to the task area.

‘Useful Light’ is the portion of a fixture’s output that is effectively delivered to the task area, discounting any wasted light. Lumens are the measure of total light intensity from a single source (in this case, a tube).

The greater the lumens, the brighter or more intense the light. A watt fluorescent tube, for example, is rated around lumens. To replace it with the same intensity LED, just look for one that rates around lumens.

Basics; Understanding LED Technology. LEDs may be little, but new high-brightness models are producing a considerable amount of light. First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six years.

How To Buy LED Bulbs for Your Home. Lighting your home or business comprises around 15% of your overall energy bills. On average, $ is spent each year to light your home. These numbers may not seem like a lot, but consider this—you can cut that expense in.

Lumen maintenance is an approach of measuring the light output (lumens) of a brand new light source and comparing that with its light output after a certain period of time.

L70 and L50 are examples of lumen maintenance – benchmarks for when 70 or 50 percent of a lamp or fixture's total light output remains.

Chances are, the LED will light briefly and then go out for good, but the LED may also melt, make a mess, and smell up your house.

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.
