First, the basic concept of artificial lighting
To say artificial lighting, we must first understand the basic concepts of lighting:
Luminous flux: The radiant energy of light that can be felt by the human eye.
Illuminance: The luminous flux density of light hitting a surface, symbolized by lux (lx).
The luminous flux of a 40W incandescent lamp is about 340 lumens (lm); the luminous flux of a 40W fluorescent lamp is about 1700-1900 lumens (lm).
It is not difficult to see from the above table that there are two ways to set up the lighting for home lighting:
1. Set two sets of programs according to general lighting and special conditions. For example, the study uses a low-power backlight and a 18-watt energy-saving lamp as the light source.
2. Set a set of programs according to special circumstances: for example, only one headlight is set in the study.
The first set of solutions described above is a preferred choice. First of all, according to different situations, choose different illuminance, which is beneficial to protect eyesight and avoid damage to vision caused by long-term over- or under-weak light. On the other hand, it is conducive to saving electricity and thus saving money.
Second, the choice of lamps 1. The style of the lamps
First of all, you must purchase lamps according to their different styles. For example, in a modern style, it is appropriate to use a combination of stainless steel and frosted glass. In the traditional style of Europe and the United States, it is appropriate to use some lamps such as rococo lines and metal powder.
Where possible, the lighting of the living room, dining room and bedroom is of the same design. According to the author's experience, this is possible. Another option is to keep the same style in the living room and dining room, while the bedroom fixtures use another style.
For the toilet and kitchen lights can be used with waterproof ceiling lamps, generally do not need to pay too much attention to the style, practical.
2. Type of bulb
Today's household light bulbs are mainly divided into incandescent lamps and energy-saving lamps. Incandescent lamps work on the principle of conductive heat generation of tungsten or other wires, and the color of the lamp is yellow. The energy-saving lamp is based on the principle of gas discharge, and its luminous efficiency is high. Its academic name is called self-ballasted compact electronic fluorescent lamp, in addition to white light, there is yellow warm light.
In general, under the same wattage, an energy-saving lamp saves 80% of electricity compared to incandescent lamps, an average life expectancy of 8 times, and heat radiation of only 20%. In the non-strict case, a 5 watt energy-saving lamp can be regarded as an incandescent lamp equal to 25 watts, a 7-watt energy-saving lamp is about 40 watts, and a 9-watt is equivalent to 60 watts. Light sources such as ring and straight tube fluorescent lamps and spotlights can also be used as needed.
However, some of the energy-saving lamp products on the market are currently at a high price and the quality is not good. If the choice is not appropriate, there will always be problems of “saving energy and not saving moneyâ€.
Another thing to note is that general energy-saving lamps are not dimmable, so only ordinary switches can be used. Do not use the dimmer switch to control the energy saving lamp. According to reports, energy-saving lamps that can be dimmed have been developed in China, but such energy-saving lamps have not been found in the market.
Third, the purchase of lamps
The purchase of lamps is more troublesome. To buy more lighting, it is best to choose a professional lighting market. Many stores only operate a certain number of manufacturers' styles, and more is the only way. Because of the concentrated style, the professional market of lamps can save a lot of effort and save the spirit, and the price is also comparable.
Fourth, the installation of special lamps
The special installation of household lamps is mainly in the shape of small ceilings. Many people like to conceal diffused lights, but not everyone can install them. The trick is:
1. End to end. Fluorescent lamps should be installed one by one. Since it is not often used with diffused lights, don't feel bad.
2. The highest position of the lamp is at the same level as the side of the lamp housing of the ceiling.
3. A small light pipe (fluorescent lamp) can be used in a curved place. Do not use a long lamp to make it.
4. The color of the lamp can be white, yellow and blue. Don't use other colors, especially red and green. The former is simply a erotic place, and the latter becomes a terrorist zone.
