The relationship between the lighting industry and real estate has been closely linked to the real estate industry has experienced ups and downs also affects the lighting industry. A property of Chongqing has been growing, so it’s good for the development of light industry. Since Chongqing became a municipality that has a real estate development has made significant progress, while the lighting industry and is closely related to real estate. Chongqing as urban sandbox provincial and rural China, support the economic center of the Yangtze has not changed, no development of Chongqing, is a significant reduction in the lighting of the estate of the industry is not tied down winter of the crisis, can not cope.

Association of Light Industry in Chongqing, Shifu Zhao a collection of objects in the sale of 07.08 in his home in Chongqing, and the future direction of the analysis of market data. Teacher said Zhao, Chongqing became a municipality has a total of 206.3045 million square meters of housing products, with a population of 187097800 square meters, 100 square feet if you count Friday suites with a total of 1,870,978 homes for sale, the spirit of two, five, if we solve a result of 4,677,445 people. commercial real estate sales 115 304 500 square kilometers (104 square meters, 497 which 800 households, which is 90.63%). 2004, sales of commercial buildings, 13,171,200 meters square, which confirms that in 1997? 2003, home sales averaged 13 million square kilometers, about 7 years, sales of 91 million square meters, of which 11.8 million are residential sales in the annual sales of nearly 7 years and 82.6 million square feet square

Judging by the housing needs of current residents, 2007, Chongqing was 876.97 million non-agricultural population, live in old houses directly under the former built on the inhabitants of the city are 4,092,255 people, most people in a 2% per year stringent requirements to buy new homes per year requires 81,845 new homes being calculated for each 100 square meters, 8,184,500 meters square, the need for new housing. 0? of 22.98 million square meters.

Judging by the growth of the population in 1997? 2007, 10 in Chongqing, the annual growth rate of urban population 28.2 million, without the Three Gorges migrants, urbanization in recent years, events and other factors, each of the next ten years the population of new cities to 20 million people is about 80,000 new homes, 8 million square meters, investment and the new home of the families, and other factors, 15,000 new homes each year area of ??1.5 million square meters while in the next decade, annual sales of approximately 17,684,500 square meters of housing is expected to grow in 1480? of 22980000 square meters.

Analysis of these data, Chongqing, commercial real estate sales each year were higher before 2006, even if it is to some extent, fall in 2007.2008, but the additional investment in Chongqing Municipality to add, replace some of the elements of an invoice again. In general, the economic crisis is affecting the lighting industry, but has little effect when used as a basis 2007.2008, is expected to fall by 20-30%, but in future there will be a little more, if the regeneration and future economic development may need to change consumption, lighting products and services, a revolutionary change, is not without the illumination of the field, Usher, again under the spring sun.

From July to late December, only to sell more than six months, the best year of sales in 2006 reached 23.4625 million meters square. Especially in December sales reached 8.1575 million meters square, the size of the level of the day. Based on sales of commercial houses of Chongqing, in addition to about 40%, sales of existing homes houses sold, usually after a year and a half million for the delivery of home residents, park is relatively small housing provided should be installed in June 2009 to June 2010 period, along with home sales fall to reduce lighting needs, the financial crisis reduce low-income people to lower expectations of good lighting, both superposition, which can affect approximately 20% of sales of lighting, but the overall level remains high in the period 2004-2005, the lighting industry in Chongqing, but a little cold in winter, but what not cold.

Although incandescent lamps are more frequently used in residential lighting applications, some commercial lighting fixtures also used this technology. Incandescent lamps pass current through a filament, which causes the filament to give off light. Because they are relatively short lived, incandescents are used mostly as decorative commercial lighting fixtures. Their ability to render warm colors effectively without ballast makes them well suited to this application, and the enormous variety of bulb designs make them highly soft after source of any type of accent lighting or decorum based commercial lighting design.

Fluorescent Lighting Fixtures
Fluorescent lamps are used extensively in commercial lighting fixtures for a number of reasons. First and foremost of these reasons is their ability to use less power than other commercial lighting fixtures, making them very cost effective from an energy conservation perspective. Fluorescent bulbs also produce a very bright light that is evenly distributed, making them ideal commercial warehouse lighting fixtures, canopy lights, security lights, in interior retail lights in discount stores where high levels of general lighting help psychologically motivate larger bulk purchases of discount merchandise.

Fluorescent bulbs produce light by activating phosphors on the interior of the bulb using ultraviolet energy generated by a mercury arc. Ballast helps start and operate the fluorescent lamps by regulating electron flow through the gaseous arc. Trends in fluorescent technology have made them more compact, increasing lumens per watt efficiency as high as 100 lumens per watt, and reducing the amount of toxic mercury within the bulbs interior. Fluorescent commercial lighting fixtures are best deployed underneath building eaves (as in the case of canopy lights), near loading docks, in wall packs on the sides of buildings, or as large grocery store or warehouse lights. Placing them too far out into open spaces tends to diffuse their light output and diminish their intensity.

High Intensity Discharge (HID) Commercial Lighting Fixtures
HID stands for High Intensity Discharge. It refers to a technology where light is produced by a gaseous arc discharge using a variety of elements. Typical elements include mercury vapor, metal halide, and high pressure sodium. The arc tube within an HID lamp will contain one or more of such elements, and when current passes between the electrodes at either end of the tube, the current creates an arc that generates visible light.

HID lamps feature the highest efficiency in lumens per watt output and also feature a greater level of lighting control. They also last longer than other commercial lighting fixtures, making them a wise investment for a company on a Spartan budget that cannot afford to continually replace equipment. High intensity discharge sources include mercury vapor, metal halide, and high pressure sodium (HPS) lamps. Light is produced in HID and low pressure sodium (LPS) sources through a gaseous arc discharge using a variety of elements. Each HID lamp consists of an arc tube which contains certain elements or mixtures of elements which, when an arc is created between the electrodes at each end, gasify and generate visible radiation.

One of the most important principles to understand when designing a recessed lighting layout is beam angle. In recessed cans, the light is produced in the shape of a cone. You picture the light starting as a point at the light fixture and forming a circle on the floor. The beam angle is the angle of this light out of the bulb. For example a 60-degree beam angle will produce a circle of light about 9 feet across on the floor if the fixture is 8 feet off the floor. See a
Diagram.

That is just one part of the formula. That circle of light we now have on the floor is not all the same intensity. About five and a half feet of that circle is good intense light while the remainder is spill over and diminishes as it gets further from the center. This is very important to understand. With this information, you can overlap the spill over light so that you end up with a nice even light pattern over the entire area you are trying to illuminate. Something to remember when you are planning this out is something called the work plane. This is an area about 30″ above the floor. It is an area where most tasks take place.

The work plane is important because as the distance between the light fixture and the surface to be lit decreases, so does that circle we spoke about. In a living room or den, designing the lighting plan so that we have even light on the floor is fine. In a kitchen though, this work plane becomes far more critical. This is why in a kitchen, keeping recessed lights about 4 feet apart, creates a pattern that is even on the work plane with the intense portion of the circle.

There are some other things besides the bulb and the can that shape the light pattern. The finish trim on recessed lights can vary the pattern of light. A wall washer creates a half cone that can be directed at a wall or fireplace. A pin spot trim can direct the light in a very narrow beam to light a small object.

This should give you a basic idea of what is involved when you undertake a recessed lighting layout. If you would like to learn more or have questions, please visit us at the links below.
