Application of LED fluorescent lamp in decorative lighting
In general indoor spaces, transitional lighting changes are not desired, and only need to ensure uniform brightness distribution and soft lighting, which can already meet the requirements of ordinary occupants for indoor space functions. This plain lighting effect has a wide range of uses. Under the illumination of diffuse light, the brightness contrast is low, which can create a plain and harmonious environmental atmosphere; under the illumination of key lights, the brightness contrast is high, which can create an environmental atmosphere where light and dark coexist. In a continuous indoor space, there should be transitional brightness. At this time, the brightness contrast should not be too large to avoid visual discomfort.
Contrast of light and shadow, the effect of light and shadow caused by contrast of light and dark, helps people and objects in the indoor space to form a three-dimensional feeling. At the same time, it can also promote the total balance of luminous flux and light intensity in the indoor space, creating a comfortable environment for people.
Light color contrast, it is best to use lights of the same light color. Under the illumination of the same light color, the illuminance contrast of the object color can be made, so as to obtain the light and dark contrast of the above-mentioned indoor space.
However, in other indoor spaces, such as exhibition halls, it is often necessary to use the hierarchical effect of lighting. This kind of lighting effect depends on the position and direction of the light and the surface state of the illuminated material. When the light shines in the indoor space, the light changes from dark to light from bright to dark. The use of dimming led fluorescent lamps creates a sharp and dilute contour contrast, forming a layered effect, just like the rendering or halo technique in painting .
Comfortable brightness distribution. Brightness is a physical quantity that indicates the intensity of the luminous surface of the light source or the intensity of the reflected light from the surface of the illuminated object. In the human field of vision, improper brightness distribution can impair visual performance, and excessive brightness differences can produce uncomfortable glare.
The brightness distribution of the building environment is an important factor that affects the visual comfort. Considering from the habits of adapting to the human eye, it is best to take the brightness distribution close to the natural environment. For example, the use of light-emitting ceilings, light strips or light eaves can create an environment in the building with a brightness distribution similar to that of the natural world. LED fluorescent lamps can come in handy. Since the luminous body is no longer a scattered point light source or a line light source, but expanded into a light-emitting band or a light-emitting surface, it can obtain high illuminance indoors while keeping the brightness of the light-emitting surface low, and due to the diffusion of light Excellent performance, making the entire space very uniform, with soft light and thin shadows. Different light sources have different color temperatures and spectral energy distributions. If the light color of the light source does not match the space tone, it will destroy the artistic effect of interior decoration, resulting in a very uncomfortable indoor atmosphere. For example, in a room decorated with yellow and red tones, that is, the warm color temperature is 2600-2700K, use cold-color fluorescent lamps 6500-7000K for lighting. Because the spectrum of this kind of lamp is rich in blue and blue components, it will make the bright yellow and red shades. The upper layer of gray shadow destroys the warm and gorgeous feeling. If you switch to a warm-toned fluorescent lamp with more red light components, the yellow and red decorations will be more vivid and warm and gorgeous.
