LED lamp as a light-emitting lighting, and other fixtures must be the same, there is the light source, then what is the light source it? LED LED light source means via dispersion system (such as a prism, a grating) after splitting, is spread by color monochromatic wavelength (or frequency) and sequentially display the size of the pattern, called spectrum. Simply put, spectroscopy revealed that the performance in relation to the wavelength of light, the light intensity distribution.
  LED downlight emission spectrum of discussions on the progress of LED luminous efficiency, promote energy-efficient LED downlights progress has great effect. Thus today Jenny Ming everybody together first and comment something about LED downlight emission spectrum of relevant knowledge.
  LED downlight spectrum measurement limit ordinary monochromatic LED, such as a blue LED with a peak wavelength of 470nm when the mountain was spread to a peak wavelength shorter ultraviolet visible and longer peak wavelength of green visible light intensity. The incandescent lamp spectrum, the luminous intensity widely distributed in many blue 400nm to 700nm and more visible near-infrared category, ultraviolet visible and infrared visible light emission intensity can be observed. Fluorescent aspect, a combination of the use of the emission wavelength of the phosphor locally as the peak of the spectrum.
  And popular red, green and blue LED spectral peak of just one match, a white LED spectrum is very divided. For example, blue and yellow Category category there are two peak luminous intensity, perhaps in the blue category, yellow and red category category has three peaks, even showing more peaks. This is because white light is a combination of a white LED of the plurality of wavelengths obtained. For example, when a combination of a blue LED and a yellow phosphor, blue peaks appear in the scope and yellow areas. In addition, based on the peak emission intensity of the blue LED more pointed, and based on the peak of the phosphor is more steep.
  When the LED for LED downlights and other popular photo offerings with tools, widely distributed in the visible spectrum of light visible white LED is more susceptible welcome. Reason is close to the natural light, the spectrum of sunlight shining light when objects close to the color of the object when illuminated with natural light.
