LED compact light-weight, low driving voltage, full-color, long life, high efficiency, resistance to vibration, easy to control light for the design of lighting systems used in different places and the purpose of providing favorable conditions. People are accustomed to seeing things in the sunlight, for general lighting, people need the main light source close to the quality of the sunlight, the white LED is an important indicator of the semiconductor lighting technology. Small single LED power light low brightness, and should not be used alone, this must be more than one LED assembly designed to be a practical LED lighting systems. However, white LED and general lighting requirements, a certain distance, there are still many technical and cost issues need to be resolved.
The main technical overview of the semiconductor lighting system
First. The heat of the lighting system
Commonly known as LED cold light source, LED light principle is issued a photon, electron after composite without the need for the hot process. However, due to the presence of Joule heat, the LED is illuminated at the same time accompanied by heat, but also for the occasions of high-power LED applications, the calories add up and can not be underestimated, the LED is different from the traditional incandescent, fluorescent and other lighting light source, the high temperature will shorten, or even termination of their service life. And the LED is a temperature sensitive device, when the temperature rises, the efficiency of a sharp decline in system architecture design and cooling technology development is also a LED applications need to face the issue. Forced air cooling is usually in the light is not desirable, with the input power increases, the heat sink and the other to enhance natural convection cooling methods play an increasingly important role in the LED lights and light design.
Second. Improve the color rendering
White LED widespread use of blue LEDs superimposed excited by blue light, yellow light yttrium aluminum garnet (YAG) phosphor, the synthesis of white light. Because of its luminescence spectrum contains only blue, yellow, two spectrum, so there is a high color temperature, and low color rendering index, does not meet the general lighting requirements. The sensitivity of human eye color is much higher than the sensitivity of the light strength of the lighting, the light source color is often more important than the luminous efficiency. So by adding the right amount of red phosphor and can maintain a high luminous efficiency white LED lighting in an important issue.
Third. Design of the lighting system of the second optical
Traditional lighting with incandescent, fluorescent light for a long time for a reference to determine the standard of optical and shape of the lamp, LED lighting system should be considered to get rid of the traditional lamp with LED light module assembly, fully consider the optical properties for thethe LED light source designed different lighting. The optical system design include the following several aspects: one, determine the optical system according to the needs of lighting objects, luminous flux, the shape, the number of LED and the size of the power; two. The number of LED light ring light source combinations designed as a point source, or "secondary source" of the surface light source, according to the combination into a secondary source to calculate the illumination optical system; three, constitute a "secondary source of illumination optical system design on each LED tube with light distribution control is very important.
Beam focus on the LED easier to control, and requires no reflector, condenser, helps to reduce the depth of the lamp. For example, using the plane mirror optical system, it can use only two LEDs can illuminate a large surface, the lighting depth is very thin; while the use of optical technology, the LED is mounted directly next to the light pipe, can greatly reduce the light source and the other group pieces of occupied volume, made of ultra-thin lamps.

What Is Native American Art?

The term Native American is representative of all the original inhabitants of the Americas, prior to European colonisation. It includes North, Central, South America, West Indies and the Eskimo nations. Despite the expansive cultural base that it symbolizes, Native American art has been relegated to the fringes of the American West until recent years. In order to determine why Native American art became peripheral, and how the change from exclusion to inclusion of culture came to be, it is important to first understand its history.

Art is said to be non-existent unless it has an audience, and that statement is very much at the root of the progression of Native American art.

In Native America, there was no word for 'art' prior to Europe's colonisation. Items were created for functional means only, and those that were better skilled were considered experts, not artists. For example, function might represent a bowl used for cooking, or a garment decorated with eagle feathers so that its wearer could take on the spirit and foresight of an eagle.

Across the different cultures and regions, many had a deep connection to the spirit world and experienced dream or waking states. From the dream state, important and inspirational messages were communicated to the tribes, sometimes through visual means. These visualisations, similar to the Aboriginal dreamscapes of native Australians, formed the basis for Native American art.

The carriers of the messages were tagged with wisdom and their purpose was linked to the collective survival of the tribe, and it can be said that art for Native American nations was more a collective rather than an individual means of expression. The freedom of individualism in European art was not practiced; nevertheless, on rare occasion, some were encouraged in that direction, like EL Blumenschein or Maria Martinez, and Iris Nampeyo, whose forms were based on old Indian pottery.

After the settlement of Europeans and the extinction of many original tribes, an ethnological interest arose. Native American art was considered more artefact than art, with emphasis placed on the historical and educational aspect of a primitive culture. The advanced cultures of the Mayans, Aztecs, Incas for example, were given precedence over other tribes, which created a segregated and less rounded understanding of the art of all Native American nations.

Considering the definition of Native American, this encompasses what is fast becoming labelled as Latin American art. Understandably, it is not possible to define such a broad movement of art into something that is easily definable. Therefore, it is no wonder that sub-divisions are evolving.

The Interest in Native American Art

In recent years, there has been an upsurge in interest in Native American art by young, knowledgeable buyers. Madonna hit the news in the 90's with her purchase of a Frida Kahlo painting, putting Frida more in the mainstream than ever before. In 2006, the final Kahlo painting was sold for $5 million which caused a jump in Native American sales. The trend continues to grow due, in large part, to collectors searching for under valued art. For example, in 2009, Sotheby's sold Diego Rivera's 'Nina con Rebuzo' for twice its estimated value.

Another reason for growth in the market arises out of the history of political tensions experienced in many of the Native American regions, most of which are in the Southern Americas, where the term Latin American art comes from. As art becomes a globalised commodity, and governments lean towards democracy, more opportunities are arising for the artists of these regions to travel and share their art.

This proves that art requires an audience before it is considered art. The art of the American West was once considered to be exclusively Native American because there was more interest in its preservation in the United States than anywhere else. This interest travelled to Europe where artists appropriated themes inherent of this region of Native America. For example, Leon Underwood's 'Manitu Bird' or Joseph Beuys's 'Action' performance piece about the transcendence to a coyote spirit.

Upcoming Native American artists to watch for, from the Innuit Nation to Mexico, are Kenojuak Ashevek, Miguel Covarrubias and Eduardo Kingman. The boundaries are being removed as the art of Native America is reclaimed fully across regions.

And hidden in many corners of all these regions, other art devoid of audience waits in silence. Like the colonialists of yesteryear, art collectors and buyers journey to unknown lands in order to discover.

Art Historian, Donovan Gauvreau lectures about art therapy with a focus on creativity development. He believes we can learn from the great masters in art to communicate ideas and feelings through painting. He provides content for Aaron Art Prints to educate and inspire people to take a glimpse into an artist's life to better understand the meaning behind their work.

For those who want to show their art to the world in a new and different way from others, fine art video is a very good option.The history of art is very old. Since thousands of years art is being used. Then the concept of fine paintings is being introduced to the world thousands of years ago. Previously, the main fine paintings were painting, sculpture, architecture, music and poetry. Drama and dancing were also considered to be good option.

Nowadays, mostly fine art is acknowledged as visual such as painting and sculpture and also performing arts like dance, theatre and music.From earlier days was considered to be only still images. Usually, painting is the very common paintings. On the other hand, the moving images or a running picture can also be a good painting. This belief has been evolved after many years since people came to know about the art. Many people call it as a video.Now, the definition of art started changing in the 1970s. A new form of art came into existence, through moving pictures. Though video art is being used many years back also, not much were ready to take it as art.
