The selection and installation of solar lamps and lanterns of lighting equipment

In decorating, one thing is indispensable to the lamps and lanterns, is not so much decoration projects, as the most basic household utensils.

one, the basic concept of artificial lighting to say

artificial lighting, first need to understand the basic concepts of lighting:

flux: the human eyes can feel the optical radiation energy.

radiation energy of each band and this band is the summation of the relative rate of visibility of the product. Unit symbols for lumen ( lm） 。

intensity of illumination, luminous flux density on the surface of the light to a symbol for lux ( lx） 。

a 40 w incandescent lamp luminous flux of about 340 lumens ( lm） ； A 40 w fluorescent lamp luminous flux is about 1700 - 1900 lumens ( lm） 。

from the table it is not hard to see, there are two kinds of household lighting lamps and lanterns is set to:

1. According to the general lighting and special circumstances set two sets of scheme. For example, a study with a small power of background light and the energy-saving light of a lamp that 18 watts for the desk lamp of light source.

    2. According to the special circumstances set up a set of solution: for example, only the study set a light lamps.

the first set of solutions is a better choice. First choose according to different situations, different intensity of illumination, is beneficial to protect vision, avoid long-term too strong or too weak light cause harm to eyesight. On the other hand, is beneficial to saving electricity, saving expenses.

2, lamps and lanterns of option 1. The styles of lamps and lanterns

must first according to the different style of their own to buy lamps and lanterns. For example, modern style, appropriate chooses some stainless steel and ground glass combination of lamps and lanterns. And Europe and the United States the traditional style, appropriate chooses some such as rococo line, the lamps and lanterns of toner coated with metal.

where possible, the sitting room, dining room and the bedroom lamps and lanterns chooses the same design style. According to the author's experience this is possible. Another solution is, sitting room and dining-room to keep the same style, while the lamps and lanterns of the bedroom use another style.

and for the toilet and kitchen lamp can use waterproof absorb dome light, generally don't need too focused on style, with practical give priority to.

    2. The type of bulb

now household light bulb is mainly divided into two kinds of incandescent bulbs and energy-saving lamps. Incandescent lamp is to use or other metal tungsten wire electric heating principle of work, light color yellow. Energy-saving lamp is using the principle of gas discharge, high luminous efficiency, its academic name is called the electron ballast compact fluorescent lamp, in addition to white, and yellow warm light.

in general, under the same wattage, a light energy-saving light electricity than incandescent bulbs 80% %, the average life expectancy longer 8 times, thermal radiation only 20% %. Not strictly, the energy-saving light of a lamp 5 watts light can be considered as equal to 25 watt incandescent lamp, 7 watts of energy-saving lamp is approximately equal to 40 watts of light, 9 watt is equal to about 60 watts. According to the need to also can use ring with straight tube fluorescent lamp, shoot the lamp to light source, etc.

but currently on the market some energy-saving lamps products price is a little bit higher, the quality is not good, if choose undeserved, tend to be 'energy-saving JieQian' problem.

another it is important to note that the general energy-saving lamps are not the light, so can only use ordinary switch. Do not use dimmer switch for energy-saving lamp control. It is reported that domestic have developed can dimmer energy-saving lamps, but there is no such energy-saving lamps in the market.

3, buy

lamps and lanterns of lamps and lanterns of choose and buy is more demanding. Buy lamps and lanterns to see, it is best to choose professional market of lamps and lanterns. Many shops only business specific a few manufacturers design, more is the only way. As professional market of lamps and lanterns design focus, choose room is big, can save energy province spirit, and the price is comparable.

4, special lamps and lanterns of

household lamps special installation place basically is modelling smallpox part, a lot of people are like dark outfit diffuse light, but not everyone can be installed. Skills:

1. The head-tail. Fluorescent lamp to pick one pack of a root. Because not often using diffuse light, so don't heartache.

    2. The top of the tube and modelling smallpox lamp chamfer edge the same level.

    3. Available with place of arc light pipe ( Fluorescent lamp) , don't make do with a long tubes.

    4. The color of light available white, yellow and blue. Don't use other colors, especially red and green. The former is a porn sites, the latter becomes a terror.
