LED Light Therapy

LED Light & Light Therapy

Incandescent bulbs produce light using electricity to heat a tungsten wire filament until it becomes “white” hot or incandescent. Thus, incandescent light (IL) bulbs release 90% of their energy as heat, and usually last about 1000 hours.

In a CFL, Compact Fluorescent Lamp, an electric current flows between electrodes at each end of a tube containing gases. This reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb.

CFLs use 1/5 – 1/3 the electric power, and last 8-15 x longer then ILB’s, but are more expensive. However, it can save over 5x its purchase price in electricity costs over its lifetime. Like all fluorescent lamps, CFL’s radiate a very toxic EMF, and contain toxic mercury: electrons that are bound to mercury atoms are excited to states where they will radiate UV light when they return to a lower energy level. When this UV light strikes the fluorescent coating it is converted into visible light, and heat when absorbed by other materials such as glass.

LED (Light Emitting Diode) lighting products produce light 90% more efficient than ILB’s: an electrical current passes through a tiny semiconductor microchip, which illuminates the tiny light sources we call LED’s resulting in visible light and very little heat. To prevent any possible overheating and burning out, the little heat LED’s produce is absorbed into a heat sink, and dissipated into the environment.

LEDs do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike ILB’s, LED “lifetime” is based on the prediction when the light output decreases by 30 %. The higher the operating temperature, the shorter the useful life will be, but usually is well over 25.000 hours.

All LED products that have earned the ENERGY STAR have been tested to ensure that they properly manage the heat, so that the light output is properly maintained through the end of its rated life.

LEDs are incorporated into bulbs and fixtures for general lighting applications. Some LED bulbs look like ILB’s, others have LEDs built in as a permanent light source. There are also hybrid approaches. Very small in size, LEDs provide unique and innovative design opportunities and fit a much wider breadth of applications than traditional lighting technologies.

When designed well, LED lighting is more cost & energy efficient, versatile, and longer lasting. 

LEDs are “directional” light sources. Unlike ILB’s and CFL’s, which emit light and heat in all directions, LED’s emit light in a specific direction. Thus LEDs are able to use light and energy more efficiently in a multitude of applications. However, it also means that sophisticated engineering is needed to produce an LED light bulb that shines light in every direction.

A 60-W incandescent bulb used 2 hr/day in an area that pays $0.11 per KWH uses $4.80 worth of electricity annually. A 60-watt equivalent LED bulb will use only $1.00 worth of electricity. Plus, a 60-W equivalent LED bulb uses only 12 watts of electricity. That’s a 75% to 80% savings in energy use and cost.

A decade from now, pervasive use of LEDs could save U.S.A. energy users 348 terawatt-hours’ worth of electricity. That’s equal to the generation of 44 big electric plants. LED bulbs reduced global carbon emissions by 570 million tons, which is equivalent to shuttering 162 coal-fired power plants.
 

Common LED colors include amber, red, green, and blue. To produce white light, different color LEDs are combined or covered with a phosphor material that converts the color of the light to a familiar “white” light used in homes. Colored LEDs are widely used as signal lights and indicator lights, like the power button on a computer.

LED’s for skin treatment

• Working principle: Utilizing LED Phototherapy technology, through dynamic skin response to light.
  It is non-invasive and has no detrimental side effects.
• The device has 3 detachable and interchangeable extra bright, 33 pc, LED panels in 3 different colors:
  • blue light of 415 nm: improving acne prone skin with its bacteria killing properties. It effectively reduces inflammation, the amount of fluid in the face and provides a clear complexion.
  • red light of 660 nm + 850 (IR): increasing the production of collagen in the skin 5-fold, also triggering the repair mechanism, and stimulating fibroblast cells and cell growth in general; reduces large pores, and is best for fine lines.
  • green light of 525 nm: reducing fleck as well as pigmentation through penetration into base skin layers, so as to keep the skin smooth and bright. It nurtures aging skin, accelerates wound healing and lightens the scar.
• The device will improve problems such as:
  • psoriasis,
  • flabbiness,
  • skin aging,
  • damaged skin,
  • large pores and fine wrinkles,
  • dark circles, eye bags and eye lines,
  • pigment lesions, like freckle, sun and age spots.

The facial mask produces 7 different wavelengths of light. Besides the above listed 3 wavelengths, there is also:

• Purple light: It is a red and blue dual-band light,
• Yellow light of 590 nm: adds energy/oxygen to skin cells, promotes gland & immune function, digestion, treatment of skin diseases, pigment decomposition, lymphatic drainage. It improves redness & rough skin, wrinkles, fever, etc.
• Green Blue light: improves the cell’s energy intake, and metabolism functioning,
• White light: deeper skin penetration reduces lines and sagging skin. It accelerates tissue metabolism, and decomposes color spots.
