Know hotel non-standard crystal droplight custom requirement?

1, luminous flux, and light luminous efficiency in unit time through a certain area of light energy, called the flux on the area. Its symbol Φ, unit for lumen ( lm） 。 1 lm is equal to the wavelength of 555 nm of monochromatic radiation and power for 1/680 wh luminous flux. Luminous flux emitted from electric power consumption per 1 w ( lm / w) Known as the luminous efficiency, photosynthetic efficiency for short. 2, intensity of illumination illuminated surface per unit area called luminous flux received by the intensity of illumination. Expressed in E, the unit for lux ( lx） 。 Uniform irradiation plane by the light intensity of illumination for the E = Φ/A. Φ- A surface receives total luminous flux, unit for lumen ( lm） 。 A - Be illuminated area, the unit is square meters ( m2） 。 3, light and spectral radiant energy, light can cause visual, it travels in the form of electromagnetic waves in space, the human eye feel the light is only a small part of the electromagnetic wave, called visible light. The wavelength of visible light unit of measure is nanometers ( nm） , is in commonly 370 - Between 780 nm range. In the light of different intensity monochromatic light according to the length of wavelength lined, referred to as the light source spectrum. 4, even if the two light source intensity, the same brightness, they caused by visually bright degree. For example, the same power an incandescent light bulb and frosted bulb. Which seem not as good as the former, because the uneven ground glass surface, light emitting area is larger, usually the luminous intensity per unit area, the surface of the light source is called the brightness of the light source, symbols, L unit for CD/m2, L = I/A. 5, luminous intensity, there is a lamp on the desk, have a lampshade is brighter than without the lamp shade, luminous flux of the bulb and now doesn't change, just flux have changed in the condition of the spatial distribution, reflected by the chimney down flux increases, when the flux in the spatial distribution of density, the luminous intensity. Capability of the luminous intensity is the characterization of light source quantity. It said the light source to the space one direction the light of the radiation flux density. Symbol for I, the unit is candela ( cd） 。 Custom crystal chandeliers in the hotel project in the process of need to give full consideration to the hotel all functional parts, each link, the focus of construction, the regional culture is an important part of the star hotel, in the custom, must be combined with each other, adhere to innovation, make they are consistent with the design theme of the hotel, finally achieve perfect harmony.
