Commonly used home decoration lamps

Household lamps, commonly used in 5 categories, as shown below

The lamp for home decoration is basically the above five categories. The LED downlight spotlight is introduced in detail below.

Application and selection of downlight spotlights

The difference between downlights and spotlights

There is basically no difference in the appearance of the downlights, but the spotlights have a concentrator or lens, which causes them to have different ways of emitting light.

The downlight of the downlight is large, and the emitted light is the same as the light bulb, which is scattered.

Therefore, the downlight is characterized by light directly below and around it.

The angle of illumination of the spotlight is small, and the light emitted is the same as the flashlight. It is a beam of light.

Therefore, the spotlight is characterized by a very glare just below, and almost no light on the side.

Suitable mounting position for downlights and spotlights

The difference between the downlight and the spotlight is that the angle of illumination is different. The direct effect is that the bottom and side of the downlight have light, but they are not too glaring, and the spotlight is very glaring directly below. (Because all the light is concentrated directly below), there is almost no light on the side. Then, when you use it at home, you must use a downlight in the area where people are often active under the lamp, especially on the sofa and on the ceiling of the bed. If you use a spotlight, as long as you look up, it will be illuminated by strong light, which is very glaring.

The most suitable place for spotlights at home is the TV background wall. The light below is strong, while the side is not light. It will not be affected when watching TV. If the TV background wall uses a downlight, because the side can see the light, it will be affected when watching TV.

Dimensions and power options for downlights and spotlights

Because the spotlights are only recommended for TV background walls, they are basically 2.5 inches (90-95 mm) in diameter and 3-5 watts in power. According to the actual situation, you can install 1-3 in the appropriate position on the TV background wall.

There are many downlights. The living room dining room and the bedroom study are recommended to have a diameter of 2.5 inches (90-95 mm) and a power of 3-5 watts. For buildings with a height of 3 meters or less, it is recommended to fit about 2 watts per square. For example, a living room with an area of ​​20 square meters requires a total of 40 watts of power. If you choose 3 watts of a lamp, you need 12-14. If you choose 5 watts, you need about 8 or so, and install it as evenly as possible.

Kitchen, bathroom, entrance porch and other places, because the required brightness is relatively high, it is recommended to use a 4 inch (15 cm) diameter, 9-12 watts downlight. These places typically require 5-6 watts of power per square to ensure brightness. For example, a 4 square kitchen is about 20 watts, so if you choose 9 watts, you can have 2-3, and if you have 12 watts, you can match 2.

Do not care about 9 watts and 12 watts, like 9 watts, more energy-saving, home electricity costs more than 5 dollars a time, a few watts of power to 500 hours to save a kilowatt, almost one month saves 5 cents. These places that require high brightness should be based on the principle of highlighting the highlights. When cooking and cooking, the mood is much better in a very bright environment.

Downlight and spotlight installation precautions

Downlights and spotlights are installed by first opening the appropriate size holes in the ceiling, then the lights are embedded in the ceiling. It is simple and generous and does not take up space. Pay special attention to the size of the openings when installing. The diameter of the openings is generally reduced by 2 cm,

For example, this 2.5-inch downlight, the opening is suitable for 80-85 mm, if you can't open more holes, the decoration should be based on the principle of opening small and not opening. Because you want to change the size when you are small, you can use a scraper like a utility knife, but if you want to change it, it is basically impossible.
