In the entire year 1952 a man by the name Lester A. Dine invented the Ring Light, it had been originally invented for the use of Dental photography. It is a circular light that fits round the lens or the protective glass of the source. By surrounding the lens or the protective glass, the same distribution of the light with fewer shadows obtained. That is very helpful in so many applications especially when shooting photos of small objects. A normal Ring Light includes two main units, power unit and source of light unit. The energy unit might be a battery or even a power pack. The source of light unit is a circular shape group of small lights surrounding the lens of the light. A number of them have a diffuser or even a focusing lamps.
LED (Light Emitting Diode) is a semiconductor light. It functions by recombining electrons with electron holes within the device releasing energy in the form of photons (bright illumination). Early LEDs emitted red light with low intensity but because the technology progressed, they offered numerous colors of light with high intensity. For example red, blue, green yellow and orange.

A LED ring light combines the Light Emitting Diode idea with the ring idea to create a very useful illumination tool. This kind of light is greatly used in Macro photography, microscope, torch, indicator light and plant grow lighting. For example in the Macro photography the item of the shot has a larger size in the picture than its size in real life.This will generate a clarity problem. A distributed illumination makes a positive change in solving this problem. Another example is replacement of the indicator light in so many devices like TVs and radios.
The advantages of using LEDs over ordinary lights are enormous, for instant lower energy consumption, better robustness, longer life, cheaper cost and faster switching. For example, a business that grows plants indoor or in green houses uses lots of electricity to power its grow lights, using LED Lights will save you up to 40% or maybe more in the power bill. They can be found in different sizes and shapes that used in many ways. This light could possibly be powered by many sources and a number of them use USB source, like the USB LED. Switching to LED Ring Lights is a very smart design especially if the project depends upon lower cost, more efficiency and longer life time.
The electroluminescent quality of the LEDs and along with of the light is determined by the power gap of the semiconductor. Quite small in area the LEDs emit stronger light with the absolute minimum use of electricity. With the reduced energy consumption and brighter light and long-lasting expected life of the lights, the LEDs are a popular and common choice in everyday life. Giving the space a beautiful and mysterious quality the LEDs are a popular to create an event mood. What helps more is the fact that these lights aren’t expensive. They’re durable, reliable, faster switching and robust.
In the industrial segments the LEDs may also be employed for aviation lighting, automotive lighting more designed for indicators, brake lamps and turn signals and also on traffic signals.
The most recent are the developments in your family segments where televisions, DVD players and certain other electronic devices have the LEDs within their manufacture. In remotes also LEDs have found their place.
Included in meal replacements the LED line lights are employed for plants. Amazing? Yes, indeed. In a number of indoor gardens the LED line lights are employed because there are some plants that need lots of sunlight. The intensity of those lights are accustomed to nourish the plants through the lights emitted. Meal replacement can be possible because the power consumed is less as the output serves to illuminate to that particular extent as needed by indoor plants. They serve to truly help the process of photosynthesis in plants and cause them to become flourish through this unique means of meal replacement for plants.
