Light - 21st November 2016 Light Product basics Light - 21st November 2016 What is a light fixture, a light fitting, a luminaire? A light fixture (US English), light fitting (UK English), or luminaire is an electrical device used to create artificial light by use of an electric lamp. A luminaire is a complete lighting unit, comprised of a light source (lamp or lamps), together with the parts that distribute the light, position and protect the lamps, and connect the lamps to the power supply.

A replaceable component that produces light from electricity is called a lamp The term light bulb comes from the particular shape that general household lamps have.

The first number indicates the measure of protection against the in- gress of solids. The second number indicates the measure of protection against the ingress of liquids.

Light - 21st November 2016 Light - 21st November 2016 Measuring Light Light - 21st November 2016 LUMINOUS FLUX (Lm = Lumens) The Luminous Flux is energy. The energy is the total amount of light energy radiated from a light source in all directions. The luminous flux is measured in lumens and is the parameter used to describe the “brightness” of a light source. Light - 21st November 2016 LUMINOUS INTENSITY (cd = Candelas) The luminous intensity of a light source is the power of light It is defined in a given direction and is measured in candela, cd. The candela is one of the seven base units of the SI system and specifies the luminous intensity in one specific angle from a light source Light - 21st November 2016 ILLUMINANCE (Lm/m2 = Lumens per metre squared) (Lux) The illuminance or light level Illuminance is invisible! It is is the amount of light energy light passing through space reaching a given point on a and not seen unless you look defined surface area. at the source or a surface it reflects off. Namely the luminous flux (i.e. lumens) per square meter. In other words we can only see “luminance” Light - 21st November 2016 LUMINANCE (cd/m2) Luminance is the amount of light energy emitted or reflected from an object in a specific direction. Luminance is the only form of light we can see. Luminance is the unit which relates to the perceived brightness of a given object.

Seasonal affective disorder Blue LightTherapy Infrared Light Therapy Red Light Therapy ChromoTherapy Colourpuncture Light - 21st November 2016 Light Therapy. Seasonal affective disorder A combination of a change in seasonal light, our hectic lifestyles and the periods of darker days and poorer weather, can result in dramatic effects on our circadian rhythms. As a direct consequence of these environmental and lifestyle factors more people than ever before are suffering from Seasonal Affective Disorder. Light - 21st November 2016 Light Therapy. Blue LightTherapy the therapy works by applying a light-sensitizing chemical solution to the skin area that needs treatment and then exposing the area to blue light. The photosensitive chemicals, which have been absorbed into the skin, react with the particular wavelength of blue light to generate reactive oxygen radicals Light - 21st November 2016 Light Therapy. Infrared Light Therapy infrared light therapy is an every-day term for the science of photobiomodulation. It uses invisible, near infrared wavelengths between 700 and 1200 nm to deliver energy to the cells, stimulating healing and relieving pain. photobiomodulation, also known as low level laser therapy (LLLT), is an emerging medical and veterinary technique in which exposure to low-level laser light or light emitting diodes stimulate cellular function leading to beneficial clinical effects Light - 21st November 2016 Light Therapy. Infrared Light Therapy Infrared light immediately follows red light on the electromagnetic spectrum. Infrared (IR) light energy is broken down into three groups: Near Infrared, also called infrared A (IR-A). Near IR spans wavelengths 760 to 1,400 nm. Most home therapy devices use these wavelengths. Mid Infrared, also called infrared B (IR-B) – These wavelengths are used in many household electronic devices such as remote controls. Far Infrared, or IR-C– also known as long wave infrared , thermal infrared (thermal-IR). This is the largest part of the IR spectrum, used in infrared saunas. Light - 21st November 2016 Light Therapy. Infrared Light Therapy Near-infrared light therapy works exactly the same way red light therapy works. Visible red and invisible near infrared energy are absorbed by photoreceptors in each cell. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body’s natural processes on a cellular level. There is an increase in blood flow, allowing the parts of the body to receive the oxygen and nutrients they need in order to function more effectively. Regeneration is stimulated. Inflammation and pain are reduced. Light - 21st November 2016 Light Therapy. Red Light Therapy Red light therapy is an every-day term for the science of photobiomodulation. There are two very different ways to look at it: first, from the viewpoint of W estern traditional medicine; and second, from the viewpoint of Eastern, energy medicine... Light - 21st November 2016 Light Therapy. Red Light Therapy Western traditional medicine likes to deal with what we can measure in a lab and prove to the FDA. Once NASA came down with undeniable wound healing results from red light therapy, conventional medicine started paying attention. Over 10 years later, red light therapy has now been thoroughly researched and FDA approved for anti-aging and pain relief Red light therapy is also used in Eastern medicine practices which focus on the energy systems of the body, specifically meridian points and chakra zones. For example, “Colorpuncture” uses a narrow beam of red light to stimulate acupuncture points instead of needles. A brand name “Photonic Light Therapy” does the same thing for animals. Red light therapy could also be called red color therapy and used to fuel overall vitality. Light - 21st November 2016 Light Therapy. Red Light Therapy - How it works... Visible red light is capable of penetrating the skin to a depth of about 8 to 10 mm. Once ab- sorbed, the light energy is converted to cellular energy, stimulating the body’s natural processes on a cellular level. Red light therapy uses wavelengths of light roughly between 620 nm and 700 nm Light - 21st November 2016 Light Therapy.

Chromotherapy Chromotherapists claim to be able to use light in the form of color to balance “energy” lacking from a person’s body, whether it be on physical, emotional, spiritual, or mental levels. Color therapy is distinct from other types of light therapy, such as neonatal jaundice treatment and blood irradiation therapy which is a scientifically accepted medical treatment for a number of conditions, and from photobiology, the scientific study of the effects of light on living organisms. Light - 21st November 2016 Light Therapy. Colourpuncture Colorpuncture, or color light acupuncture, is an alternative medicine practice asserting that colored lights can be used to stimulate acupuncture points to promote healing and better health. It is a form of chromotherapy or color therapy. There is no known anatomical or histological basis for the existence of acupuncture points or meridians.Colorpuncture is in the early stages of scientific research. Colorpuncture employs seven basic colors. In general, the warm colors - red, orange, and yel- low - are believed to add energy, while the cool colors - green, blue, and violet - decrease energy. Mandel also claims that warm and cool colors, when used together, balance yin and yang energy flows. Light - 21st November 2016 Light Therapy. Colourpuncture A small handheld instrument resembling a torch (flashlight) with a colored quartz rod is used. The tip is placed directly onto acupoints or held a short distance above. Unlike acupuncture, the skin is not broken. Colorpuncture sessions last 10 to 90 minutes.
