How to calculate the number of power LED lamp in the living room?
Built in speaker, two row Tongdeng, four each row, each row of two wide. In general Home Furnishing lamp decoration inside, on a ceiling decoration, in fact, the role is not big, or by the general lighting lamp, downlight is auxiliary light source, watch TV in the evening, the lights off, you can open one or two row Tongdeng, auxiliary light source 8W can 5W 3W. Living room four sides, you each side of a group, can be a group of a group of open. It saves a lot of electricity.
LED is the application of a new type of LED lighting lamp based on traditional lamp on development of improved products, has the following advantages: compared with the traditional lamp energy saving, low carbon, long life, good color, fast response. Appearance design of LED downlight more lightweight, can achieve the overall unity and maintain perfect architectural decoration installation, does not damage the lamp set, light source inside a building decoration, the light source is not exposed, no glare, the visual effect is soft and uniform.
70 square meters large living room, if only 20+ holes can choose 4 inch or 6 inch downlight, luminous flux of single lamp preferably above 1000lm. 3W, 5W downlight is not enough. According to the existing relatively high efficiency downlight, 1W output luminous flux of 100lm, also have more than 10W downlight.
The LED lamp efficiency uneven. First use LED lights, it is best to see their luminous flux value. The same luminous flux value, the power is high, but more power consumption
