Technical field
Lampshade that the relevant a kind of high brightness of the present invention shows and preparation method thereof.
Background technology
As shown in Figure 1, tradition is as the brightness abundance of the bulb 10 of lighting source, and for preventing that dazzle is dazzling and promote the soft of light, the light 14 that uses translucent lampshade 12 to allow bulb 10 send partly penetrates lampshade 12, but this kind light source is short than power consumption and life-span.
Light emitting diode (LED) also is used as light source because the life-span is long and advantage such as power saving, but because the shortcoming of luminance shortage, on using still based on ornament lamp.As shown in Figure 2,, use translucent optical mixing cover 22, yet when light 24 was radiated on the optical mixing cover 22, most light was blocked by optical mixing cover 22, cause brightness to reduce for the coloured light that makes LED 20 rests on the lampshade.In order to improve brightness, ornament lamp is always towards the LED of high power and big lumen value development, but high-power LED costs an arm and a leg also than power consumption.Moreover LED is that the area source angle of visibility is limited, and as shown in Figure 3, therefore in the application of general illumination, spot light is only preferable light source, as shown in Figure 4, so LED is confined to the development of projecting lamp and uses always.
Fig. 5 is general tail-light 30, and it comprises that a light source 32 and has the lampshade 34 of the three-dimensional taper rag 342 of rhombus.Fig. 6 is the profile of lampshade 34 among Fig. 5.Fig. 7 is the partial enlarged drawing of lampshade 34 among Fig. 6.Because lampshade 34 is a transparent material, so the three-dimensional taper rag 342 of rhombus that the incident light 322 of working as light source 32 is radiated on the lampshade 34 will produce diffused light 324, reverberation 326, refract light 328 and penetrate light 329, wherein only there is diffused light 324 can reach the effect at full visual angle, but luminance shortage, though and reverberation 326 with penetrate light 329 and have high brightness, but the direction of reverberation 326 is towards light source side, penetrate light 329 then because the three-dimensional taper rag of incident light and rhombus 342 angulations make that penetrating light 329 only just can see at certain visual angle.The design of the three-dimensional taper rag 342 of rhombus focuses on the reflective design of external light source, so in the projection of the light source in lampshade, the showing can't be obtained of the brightness and the uniformity.
Fig. 8 is the Transparent lamp shade 36 that multi-angle penetrates the light scattering design that has commonly used.Fig. 9 is the profile of lampshade 36 among Fig. 8.Have many semi-round balls 362 on lampshade 36 one side outwardly and form intensive salient point, one side towards light source 38 then is a plane, the effect of lampshade 36 first balls 362 is just as convex lens, when the incident light 382 of light source 38 enters semi-round ball 362 focuses, to form multi-angle and penetrate light 386 outside scatterings, yet, when incident light 382 is radiated at lampshade 36, most incident light 382 is reflected and forms reverberation 384 towards light source 38, thereby has reduced brightness.
Therefore, the lampshade that provides a kind of high brightness to show is extensively expected.
