The specific embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
Fig. 1 is the structural representation of LED traffic light optical assembly.Fig. 2 is the schematic diagram that the partial structurtes of LED traffic light optical assembly are amplified.As shown in Figure 1-2: the utility model comprises optical mask 1, signal lamp back shroud 2, optical mask 1 and signal lamp back shroud 2 are movably connected, the utility model also comprises LED card 3, LED card 3 is fixed on signal lamp back shroud 2, a plural number LED traffic lights 4 are arranged on LED card 3, each in LED traffic lights 4 is all provided with LED lens 6 that cover on outside LED traffic lights 4 on only, optical mask 1 is one by a plurality of little micro mirrors 101, to be arranged in a face shield on supporter 102, on optical mask 1, have that little micro mirror 101 arranges one facing to LED lens 6, LED traffic light optical assembly also comprise one and optical mask 1 be fixed together the Fresnel Lenses 5 that changes light path, on optical mask 1, there is the one side of little micro mirror 101 arrangements towards Fresnel Lenses 5.Fresnel Lenses 5 is arranged on to be had on optical mask 1 between the one side of little micro mirror 101 and LED lens 6.
Fresnel Lenses is respectively arranged with space near the one side of LED lens and close little micro mirror, is greater than the space of the one side of close little micro mirror near the space of LED lens.Generally can select following multiple relation: the 5-20 that Fresnel Lenses is the height in the space of the one side near little micro mirror near the height in the space of LED lens doubly.
The number scope of LED traffic lights is 2-10, between LED card 3 and signal lamp back shroud 2, is provided with heat sink 8.In order to guarantee better radiating effect, between signal lamp back shroud 2 and heat sink 8, be provided with heat-dissipating space 7.
The Fresnel Lenses using in the utility model (Fresnel lens), claim again Fresnel lens, by French physicist's Augustine Fresnel (AugustinFresnel) utility model, he is initial in 1822 uses this Lens Design to be used for setting up a glass Fresnel Lenses system---lightose lens.Mostly Fresnel Lenses is to press by polyolefine material note the thin slice forming, also have glass to make, lens surface is simultaneously light face, another side imprinting ascending concentric circles, its texture utilizes interference of light and disturbs and penetrate and require to design according to relative sensitivity and receiving angle, the requirement of lens is very high, and the lens of a slice high-quality must be any surface finish, clean mark, its thickness becomes with purposes, how, in 1mm left and right, characteristic is that area is larger, thin thickness and detecting distance.
Fresnel Lenses effect has two: the one, and focussing force; The 2nd, will in search coverage, be divided into several area pellucidas and dark space, the motive objects physical efficiency that makes to enter search coverage is released infrared signal with the form of the variations in temperature heat that changes on PIR.Fresnel Lenses many times, be equivalent to the convex lens of infrared ray and visible ray, effect is better, but cost is more much lower than common convex lens.Being used for required precision is not very high occasion, as slide projector, film magnifying glass, Infrared Detectors etc.
Fig. 3 is the structural representation of optical mask.As shown in Figure 3: after the supporter 102 of optical mask 1 and 101 one-shot formings of little micro mirror, become all-in-one-piece optical mask.
Fresnel Lenses 5 is an intermediate thin, the thick Fresnel Lenses in both sides, and the helical groove 501(that is provided with sawtooth pattern in the one side of the little micro mirror 101 of close optical mask on Fresnel Lenses is referring to Fig. 2).
Fresnel Lenses Main Function is for converting the light of LED traffic lights 4 transmittings to directional light, and Fresnel Lenses is the same with common planoconvex spotlight principle, light source is placed in the focus of lens, and light becomes directional light after lens reflection.The refraction of Fresnel Lenses hypothesis lens light only occurs over just optical surface (as: lens surface), takes away optical material as much as possible, and the flexibility of retention surface, the effect of generation remains unchanged.
The utility model adopts the mode that " optical mask 1 "+" Fresnel Lenses 5 "+" LED lens 6 " combine, and is the effect comparison diagram of several different optical combinations below:
From test data and distribution curve flux, 1 and 3 combinations all can meet the optics requirement of signal lamp, but the face sight effect of 1 combination will be better than 3 combinations far away.Therefore 1 of comprehensive above-mentioned combination effect employing mode can reach best effect.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
