The color of the light intensity changes can be described by the data, this data is called the wavelength. The wavelength of light that we can see is in the range of 380 to 780nm. Unit: nanometer (nm)
Brightness is the degree of light and dark of the objects, defined as the luminous intensity per unit area. Unit: nits (nit)
refers to the brightness of the light source. That means that the visible radiation source in a certain direction and scope given physical strength. Unit: candle (cd)
The sum of the amount of visible light emitted per second. Unit: Lumen (Lm)
light flux divided by the power source. It is an important indicator to measure the light energy. Unit: lumens per watt (Lm / w).
degree that light reflects of the object presented, which is the degree of color fidelity, which is often called “CRI” units: Ra.
the color of a light source for emitting light radiation from a blackbody at a temperature at the same hue, the color temperature of the blackbody temperature is called the source color temperature. Unit: Kelvin (k)
the vision has a high brightness of objects or strong brightness contrast, which caused visual discomfort known as glare, glare is an important factor affecting the quality of lighting.
two or more LED lamps normal operation mode at the programmed time, which generally refers to the internal mode of the LED, synchronization is the basic requirements for achieving coordinate changes of the LED lights.
IP protection class is grading the lighting according to their dust, anti-moisture characteristics, which is consisting of two figures, the first number represents the light dust, prevent the invasion of foreign material grade (grade 0-6 points), and the second number represents the lamps against moisture, water intrusion sealing extent (points 0-8 grade), the larger the number is, the higher their level of protection is.
LED Floodlights, the bottom of lamps, chandeliers, lamps and other decorative projection and reflecting the use of LED lighting which can be fully qualified for any occasion, including art galleries, museums, etc. require a higher degree of color spaces.
However, for shopping malls, office buildings and other large-scale facilities, LED ceiling light as the wide range of lighting have been born though, but its directivity (LED chip emits light line, divergence is bad) is too high, resulting in a large area design is difficult in the average illuminance. Lamp type LED lighting arrangement is too dense, with high design costs, which loss of energy savings. Therefore, at this stage decorative purposes occasions, LED lighting is fully available, as a large area of indoor lighting, it is not yet ripe.
