The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment, the invention will be further described.
Fig. 1 shows the structural representation of illuminating lamp of the present invention.As shown in Figure 1, described illuminating lamp comprises lens module, optical fiber 100 and light-emitting plate 400.Wherein, described lens module comprises housing 200 and is arranged in the optical lens 300 of housing; described optical fiber 100 stretches in described lens module as lens module is carried light; the below that described light-emitting plate 400 is connected to described lens module is used for the light in lens module to penetrate and realize illuminating effect, simultaneously for lens module provides protective effect.
According to the demand of illuminating effect, can select different optical lens types, for example, while needing comparatively soft illuminating effect, can choice for use such as concavees lens or other lens subassemblies that can spread light.Now, the Shu Guang being derived by described optical fiber 100 expands after being arranged in the optical lens 300 of housing, expands light and after described light-emitting plate 400, transmits to reach the effect of illumination, has prevented dazzle, makes light become soft.Described housing 200 is opaque housing, its inner side coating layer of metal face, and metal covering is silver-colored face or aluminium face, the light that is diffused into housing internal layer is reflexed on optical lens and then is spread out by metal covering, has improved the utilization rate to light.For example, and if during illuminating effect that need to be comparatively concentrated (light converges to the lighting demand of a bit), can choice for use such as convex lens etc. can form the lens subassembly of assembling stiffening effect to light.Now, the light that enters lens module converges by light-emitting plate and penetrates through wherein having the optical lens of the effect of converging.Owing to such as lens subassemblies such as convex lens, light also being had to converging action, the light that penetrates light-emitting plate is concentrated as a bit, and brightness is stronger, can meet special illumination demand.
When choice for use concavees lens spread light, the number of described concavees lens can be for one or more according to lighting demand choice for use, and the quantity of concavees lens is more, stronger to the diffusion effect of light beam, and the scope of diffusion is also just larger.The concavees lens that use are for being plano-concave lens or biconcave lens, and plano-concave lens is the flat lens of the recessed one side of one side, and biconcave lens is that two sides is all recessed lens.Except concavees lens, the combination of choice for use concavees lens and convex lens in an alternative embodiment of the invention, by both relations of reasonable Arrangement, realizes the diffusion to light.
In illuminating lamp of the present invention, described optical lens 300 is plastic cement lens or glass lens.Described optical lens 300 can be divided into silica-gel lens, PMMA lens, PC lens and glass lens by material.Silica-gel lens heatproof is higher, is often directly used in packaged LED luminescent device, but general silica-gel lens small volume, and diameter is 3-10mm; PMMA lens are commonly called as acrylic lens, are plastic cement lens, and the production efficiency of these lens is high, and light transmittance is high; PC lens are polycarbonate lens, are plastic cement lens, and the production efficiency of these lens is high, low compared to PMMA lens transmission; Glass lens has the advantages such as light transmittance is high, high temperature resistant.
In illuminating lamp of the present invention, described optical fiber 100 is multimode fibre.The core diameter of multimode fibre is thicker, can transmit the light of various modes, and the angle that incident light enters fibre core is many, and the path of propagating is forward also many.From operation wavelength, optical fiber can be divided into UV fiber, considerable optical fiber, near-infrared fibre-optical, infrared optical fiber, the light of illumination is all visible ray, and the optical fiber that described illuminating lamp is used is considerable optical fiber.In index distribution optical fiber common be step index fiber, nearly step index fiber, graded fiber.The material of described optical fiber is quartz glass, and this optical fiber has advantages of that cost is low, light transmission good and is convenient to processing.
When the comparatively soft lighting demand of needs, described light-emitting plate 400 can have the light diffusing sheet of diffuse transmission effect by choice for use to light.In light diffusing sheet, add the diffusion particle that has the interference of light, make light when by base material, because refractive index is different, realize repeatedly refraction, thereby light is disperseed uniformly, reflection, scattering, adjust light and propagate to obtain direction, make spot light become area source, because the light of loss part makes, light is softer does not have a dazzle.Can choice for use acrylic board or PC plate as light diffusing sheet.Acrylic light diffusing sheet is to take polymethyl methacrylate as base material, adds diffusant to make; PC light diffusing sheet is to take Merlon as base material, adds diffusant and a kind of optics PC force-bearing plate of making.
The profile of described light-emitting plate 400 can be designed to any shape, the geometry of rules such as circular, square, triangle, prismatic or irregularly shaped as shown in Figure 2.The exiting surface of described light-emitting plate 400 can be plane, thereby also can be designed to have the on-plane surface just rising and falling, forms various three-dimensional shapes.For example, when described illuminating lamp is placed in graceful environment, the exiting surface of described light-emitting plate 400 can be designed to artificial hillock etc. and there is artistic three-dimensional shape.Can also on the exiting surface of described light-emitting plate 400, post optical filter, to see through as required the light of different colours.
In illuminating lamp of the present invention, between described lens module and described light-emitting plate 400, can adopt such as being threaded or buckle is connected etc. and removably connects.Being threaded is a kind of widely used dismountable being fixedly connected with, and has the advantages such as simple in structure, connection is reliable, mounting or dismounting are convenient.Be threaded to screw is directly screwed in the screwed hole of described lens module and described light-emitting plate 400, reach described lens module and the close-connected effect of described light-emitting plate 400.Buckle connects and is divided into the buckle connection (as shown in Figure 3) of cantilever beam type, the buckle connection (as shown in Figure 4) of cylinder type and the buckle of ball-type are connected (as shown in Figure 5).When described lens module is used buckle to be connected with described light-emitting plate 400, the mode that buckle connects is chosen as the buckle connection of cantilever beam type or the buckle of cylinder type connects.
The optional many factors of optical lens combination method proposing according to the present invention, can design various embodiments, so specific embodiment is only as the exemplary illustration of specific implementation of the present invention, and does not form limitation of the scope of the invention.For concrete description the present invention, select following examples to carry out exemplary illustration.
