Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail:
Embodiment 1
As shown in Figure 1, a kind of device using monochromatic light to transmit reduction white light of the present utility model, it comprises monochromatic source 1, and described monochromatic source 1 is for sending monochromatic light.During the white light using Optical Fiber Transmission white light source to send, the wavelength light energy loss that after white light long range propagation, loss is larger is larger, last total light energy reduces, and even occur the situation of photochromic distortion, optical fiber light transmittance after each wave band loss of visible ray and optical transport changes as shown in Table 1.
Table one

Table two
Contrast table one is visible with table two, LED blue light monochromatic source is adopted to transmit, input at same light flux (lumen), after the transmission of equal length 50m plastic optical fiber, light transmittance uses 47.39% of blue transmission from using 21.78% of white transition to increase, and increasing degree is about 120%.
After adopting the transmission of same light flux (lumen) laser blue light monochromatic source, light transmittance change is as table three:
Table three
Contrast table one is visible with table three, laser blue light monochromatic source is adopted to transmit, input at same light flux (lumen), after the transmission of equal length 50m plastic optical fiber, light transmittance uses 50.12% of blue transmission from using 21.78% of white transition to increase, and increasing degree is about 130%.
Adopt same light flux (lumen) LED blue light monochromatic source to reach identical with white light light transmittance 21.78% time transmission length as table four:
Table four
As shown in Table 4, the LED white light source of same light flux and LED blue light monochromatic source, after the transmission of same plastic fibre bundle, reach identical light transmittance 21.78%, transmission length is increased to the 102m of LED blue light monochromatic source by the 50m of LED white light source, increasing degree is 104%.
