Description

Crystal lamp lamp source

Technical field

The present invention is about a kind of lamp source, especially about a kind of Crystal lamp lamp source.

Background technology

As shown in Figure 1; A plurality of polyhedrons 104 that have a plurality of refraction walls respectively distribute around the light source 102 of existing Crystal lamp 100; Though these polyhedrons are a kind of dispersion elements; But the light I that sends because of light source 102 is the light beam of dispersing toward all directions, and only utilizes the anaclasis effect of wall refracted ray I of differing tilt angles limited, dazzles beautiful colorful visual effect so can't produce.In addition, as shown in Figure 2, the wall profile of Crystal lamp 200 can constitute a fine rule 202 with raising anaclasis effect, but the anaclasis effect that this designing institute provides is still limited.Moreover the Taiwan patent announcement discloses for M255922 number a kind of in the design of optical fiber surface formation multiple spot micro-structural with the raising refraction effect, lists reference in the lump in this.

Please refer to Fig. 3 A, Fig. 3 B and Fig. 3 C, Fig. 3 A shows a high Ra value bulb lamp (the Ra value is represented the color rendering index), and Fig. 3 B shows that one has the bulb of many high directivity light sources, and Fig. 3 C shows the conventional bulb of a tool fine rule light source (for example tungsten filament).In practical application; Anaclasis effect through the above-mentioned three kinds of bulbs of comparison; Can know: the anaclasis effect of the bulb of many high directivity light sources of tool (Fig. 3 B) and fine rule light source (Fig. 3 C) is preferable; Can produce and dazzle beautiful colorful visual effect, and the anaclasis effect of high Ra value bulb lamp (Fig. 3 A) is relatively poor.Because of quartzy polyhedron can be considered a prism dispersion element, the prism dispersion values depends on the character of prism, shape, lambda1-wavelength and the incident light direction etc. of prism.High directivity multiple spot light source and fine rule light source are advanced because of light and in the space, are had discrete distribution than tool directionality and light source, so preferable chromatic dispersion effects can be provided.
