Background technology
In the decorative lighting field, optical fibre illumination is a kind of environmental protection, new mode of decorative lighting safe, energy-conservation, easy to maintenance, that effect is unique to one of melting.Particularly optical fibre illumination is that light separates with electricity, and has only visible light not have infrared and ultraviolet light, much electric or hot and non-visible light activated occasion is being got rid of various hidden danger, and the safety of guaranteeing decorative lighting is with reliable.Mainly by light source generator control, conversion is abundant for optical fibre decoration lighting colour, and same optical fiber can be transmitted to various colors in the people's sight, realizes the effect with point or collinear variable multiple color.Existing optical fiber illuminating system all is the single-point light structures basically, can not realize the large-scale multiple spot illuminating effect of hundreds of rice.
Summary of the invention
The purpose of this utility model is a kind of luminous power height to be provided, to control distribution type fiber-optic illuminator easily for decorative lighting.
For reaching above-mentioned purpose, the utility model has following two kinds of technical solutions.
Scheme 1:
The distribution type fiber-optic illuminator, comprise two light sources, two couplers and one section fibre bundle, has a n spaced apart fiber optic loop on the fibre bundle, n is a positive integer, covering on each fiber optic loop is partly peeled off, the two ends of fibre bundle link to each other with an end of first coupler and an end of second coupler respectively, and the other end of first coupler links to each other with first light source, and the other end of second coupler links to each other with secondary light source.
Scheme 2:
The distribution type fiber-optic illuminator, comprise a light source, a coupler and one section fibre bundle, has a n spaced apart fiber optic loop on the fibre bundle, n is a positive integer, covering on each fiber optic loop is partly peeled off, one end of fibre bundle links to each other with an end of coupler, and the other end of coupler links to each other with light source.
In above-mentioned two kinds of schemes, said light source can be light emitting diode or glow discharge spot lamp.Said fibre bundle can be made up of 100～1000 root multimode fibers, plastic optical fiber or glass optical fiber.
Distribution type fiber-optic illuminator of the present utility model, utilize photo-coupler that optical fiber is advanced in the optically-coupled of light source, pass light by fiber guides again, when light passes through fiber optic loop in the process of transmission, have partial mode to leak out (this pattern is called tunnelling ray) in the light wave pattern from optical fiber, this part light just directly is used for decorating or illumination.By the cladding thickness of control fiber optic loop and the diameter of fiber optic loop, can control the power proportions of leak light in the fiber optic loop.By changing the power of light source, also can reach the power of control illumination light.The utility model concentrates in together the formation fibre bundle with a large amount of (100～1000) optical fiber, can reach than higher luminous power.
The beneficial effects of the utility model are:
Distribution type fiber-optic illuminator of the present utility model can realize multiple spot distributed lighting on a large scale, and the control of illumination light power is convenient, and can obtain higher luminous power, and cost is low, and is safe in utilization, reliable, easy to maintenance.Can be widely used in special decoration illumination occasions such as decorative lighting, landscape design, public place of entertainment and industry, medical science, museum, coal mine.It is 10 meters～300 meters that the typical case of this system is suitable for distance.
