LED lighting design considerations

　　LED lighting design must consider flux and the illuminated object or an illuminated plane flux is obtained by illumination. The unit of measurement is the lumen luminous flux (Lumen). Illumination unit of measurement Lux. The relationship between 1 Lux = 1 Lumen/m2. Suppose there is a 10W of LED spotlights, issued to the total flux is 900 Lumens. If this 900 Lumens all concentrated in one square meter of the ground, and that ground illumination is 900 Lux.

　　Commercial premises - commercial lighting is not only able to see four weeks to reach the required items, but also need to meet to stimulate consumer desire to buy, regulating the role of consumer psychology. Bright foods, such as bread, pizza, braised pork, barbecue, etc. can stimulate appetite, mouth wide open the purse after Flows. So bread cake, hamburger fast food and restaurant windows have a 1000 Lux or more illumination. Jewelry, watches, clothing stores, but also must have a bright illumination to stimulate the desire to buy. Precision factory, color printing, optical shops, 3C stores also should have a 1000 Lux illumination.

　　Ordinary places - offices, classrooms, bookstores, Supermarket Department, cafes, fast food restaurants, factories, hospitals and other places, you have 300-800 Lux, because it is too bright will make people excited, and fatigue.

　　Activities occasions - such as railway stations airports, gym, building halls, wards, corridors, stairwells, toilets 100-300 Lux, requires the ability to recognize faces and more distant to see the books and text.

　　Leisure places - parks, parking lots, streets and other small objects do not need to read and see the place it can be as low 10-100 Lux.
