Look at the difference between spotlights and downlights first? Track spotlight: It is just a condenser, and some actors must highlight the lighting. For example, track spotlights are used for decorative painting, wall washing and painting, and the light spots are stacked one after another, which is full of high-grade feeling. Different types of practical effects can also be achieved by adjusting the irradiation position, which is suitable for various TV background walls. Ceiling lamp: just defocusing, mainly to help illuminate lamps. Suitable for corridors and aisles.
How to choose contrast? Simply put, the smaller the contrast, the smaller the chromaticity, the yellower the light source, the greater the contrast, and the brighter and bluer the sunlight. It is generally recommended that the living room and bedroom be between 3000 and 3500 K, which is very warm. Like bathrooms, dining rooms, kitchens and small study rooms, it is recommended to be between 4000 and 5000 K, which is brighter. In fact, from my own experience, the more consistent the comparison of the same public space, the better. 3000-3500k likes warm spots, and 4000k likes bright spots. A light source over 4000 K will feel a little blue, and I don't think it is suitable for home use.
How to choose color development? Chromaticity refers to the authenticity of the influence of light on hue. The greater the index value, the more unique the color, making furniture, decorative oil paintings and decorations look more layered. Generally choose the middle of 80-95 degrees.
How to choose the beam angle? Simply put, it is the intersection angle formed by the boundary line in the light area. If used to paint the wall, the actual effect is the size of the light arc of the hill.
It is highly recommended to use household optical glue: 15 degree: it is suitable for focusing spot lighting and central condenser, with a small irradiation range, which can produce strong contrast between light and dark light, such as columns, decorations and indoor spaces with the most prominent light and shadow. 24 degrees: It is suitable for accent lighting, beam angle with bright central light, and the irradiation range is much larger than 15 degrees, resulting in the shape of hills. It is used for special effects spaces with light and dark levels in coffee tables, dining tables and mini-bars. 36 degrees: the central light is mild, the irradiation range is larger and shorter than that of 24 degrees, resulting in a larger light arc, which is suitable for indoor spaces with a slightly larger total area, such as washing walls, taking photos, patting rock slabs, etc.
