A kind of efficient fibre bundle led light source system

Technical field

The utility model relates to a kind of light-source system, especially relates to a kind of efficient fibre bundle led light source system.

Background technology

At present, fibre-optic bundle (abbreviation fibre bundle) has been widely used in a plurality of fields such as decoration, illumination, medical treatment, most fibre bundle adopts the mode of direct irradiation with light-source system, be that the light that light source sends directly shines to the fibre bundle end face, some luminous energy coupled into optical fibres bundle only wherein, because the angle of divergence of general light source is big, and the fibre bundle diameter is little, cause coupling efficiency low, energy loss is big, and being subjected to the restriction of light-source brightness and coupling efficiency, the output brightness that improve fibre bundle is difficulty.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, a kind of efficient fibre bundle led light source system is provided, its compact conformation, reasonable in design and coupling efficiency is high, can solve effectively that the coupling efficiency that exists in the prior art is low, energy loss is big and the problem of the difficult raising of brightness, it is little to have volume simultaneously, cost is low, brightness height, the characteristics of energy-conserving and environment-protective.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of efficient fibre bundle led light source system, comprise housing, it is characterized in that: described enclosure interior left side is provided with led chip, snoot and fin, described led chip, snoot and fin all are positioned at housing top, described fin is installed on the housing, and described led chip and snoot are installed in the fin right-hand member, and described led chip is positioned at place, snoot focal position; Described enclosure interior also is provided with the drive circuit that is used for the driving LED chip, described drive circuit is positioned at lower housing portion, described enclosure interior right side is equipped with the fibre bundle socket, described fibre bundle socket inside is provided with reflective light cone, described reflective light cone and led chip are positioned on the same axis, and described fibre bundle socket right-hand member is plugged with fibre bundle.

Above-mentioned a kind of efficient fibre bundle led light source system is characterized in that: described reflective light cone and fibre bundle socket are one-body molded.

The utility model compared with prior art has the following advantages:

1, compact conformation, reasonable in design, this light-source system adopt led chip as light source, utilize snoot and reflective light cone that luminous energy is coupled to fibre bundle efficiently.

2, coupling efficiency height can solve effectively that the coupling efficiency that exists in the prior art is low, energy loss is big and the problem of the difficult raising of brightness, and then makes whole system capacity usage ratio height, the brightness height.

3, because each parts are installed in the housing, make whole light source system architecture compactness, volume is little.

4, it is low also to have a cost, the characteristics of energy-conserving and environment-protective.

Below by drawings and Examples, the utility model is described in further detail.
