The specific embodiment
Below in conjunction with accompanying drawing further statement is done in enforcement of the present invention:
Embodiment one: as Fig. 1, printing opacity cylinder 2 is inner distribution literal or pattern 4, the cylindrical light penetrating object made from the PMMA material.Lampshade 3 is mounted in the reflector of cylindrical printing opacity cylinder 2 another tops, bottom surface.High-power LED light source 1 is high-power spot light, spot light incident ray (not shown) is through the logical coupling of full light, incide printing opacity cylinder 2 inside with various angles from a bottom surface of printing opacity cylinder 2, its most of light is gone out from another bottom surface transmission of printing opacity cylinder 2, reflex to through the reflecting surface of lampshade 3 then and become the key lighting of electric lighting light on the face to be illuminated, another part reflects away from the side of printing opacity cylinder 2 becomes floor light light, and having only minimum part to be absorbed by printing opacity cylinder 2 becomes invalid light.The light that the side transmits has been the even soft light of no direct glare.Another part is gone out through the light of lampshade 3 reflection because the control of reflector lamp shielding angle α also is the main illuminating ray of having eliminated direct glare, has made three-dimensional free from glare illuminator from another bottom surface transmission of printing opacity cylinder 2.
Here the know-why of printing opacity cylinder 2 is given explanation: the light major part of the LED illuminator light source in the high-power LED light source part 1 directly is transmitted in the printing opacity cylinder 2, the less transmission energy of loss only in this process.Total reflection principle according to light transmits luminous energy effectively simultaneously, changes LED illuminator light source into printing opacity cylinder area source.Know by the light total reflection principle: as shown in Figure 2: when light from the high medium of refractive index during to the low medium of refractive index (as plastics to air) refraction, the light that is refracted is with the angular emission more oblique than incident ray, when incidence angle during greater than a certain angle, light can not be refracted into the phenomenon of medium and comprehensive generation of air to internal reflection, be called total reflection or internal reflection, the incidence angle when the refraction angle equals 90 ° is called critical angle.The law of refraction and formula n according to light
