Description
Technical field
The present invention relates to a kind of reflection shield and application thereof, especially a kind of highly effective slot-shaped reflective cover and the application in the LED street lamp thereof
Background technology
Along with led chip technology and Development of Packaging Technology, comply with the demand of lighting field to high light flux LED product, power-type LED progressively enters into market, is applied in the road lighting especially gradually.With respect to traditional 5mmLED, power-type LED has higher output light flux, and the angle of divergence is also bigger, applies to the road lighting field effectively for making great power LED, need carry out the secondary optics design to LED according to the LED light-emitting mode, satisfy the road illumination standards of LED street lamp.
The power of traditional street lamp is that 150w is to 400w, but because the volume and the angle of divergence of these road-light light-sources are all very big, be not easy to its light-emitting device effectively design so that the optical energy irradiation of light source in the effective range on road surface, thereby optical energy loss is serious, cause to waste energy, bring very big pressure for the consumption of the energy.And great power LED is brought into play very big advantage in this respect, can make full use of luminous energy by effective light-emitting device design.
The light-emitting device of LED street lamp comprises two kinds substantially on the domestic and international market at present: first kind is not use any optical element, directly the light that LED sent is shone the road surface without any shaping, the light-emitting mode of LED self places one's entire reliance upon, so the utilization scope is very narrow, be not suitable for doing the street lamp of the above lamp stand of 6m; Second kind is the mode that adopts lens and sloping portion LED, with lens the light beam that LED sent is carried out shaping, increases range of exposures by inclination LED again.
The CN2842182Y patent documentation discloses a kind of " LED street lamp ", and the LED in this street lamp is that intensive being installed in laid on the plate, lays the plate middle part and is surface plate, and periphery forms angle to the installed surface perk in the other direction of LED, and the installed surface of whole LED is convex.In this scheme, the irradiating angle that is constituted for the LED street lamp is realized by the raised land of installing plate.
The CN1821651A patent documentation discloses a kind of " high-power LED street lamp ", and this road lamp cap is socketed with corresponding lens, and lens are fixed by securing cover plate.In this scheme, the light that LED sends need be shone in the road surface by diffuser through behind the lens in the lens opening.
The CN2896006Y patent documentation discloses a kind of " high-brightness LED street lamp lamp holder ", is provided with arch support in the lamp holder, and each great power LED is provided with the lens that supported by lens carrier respectively, the light that LED sends by lens lighting in the road surface.
The CN1936417A patent documentation discloses a kind of " LED road-light light-source ", the light-emitting device of this street lamp is that LED is installed on the bottom surface at the heat radiation seat of honour, the bottom surface is made of a plurality of clinoplains that form an angle each other, the LED scioptics entangle, with lens fixed mount fixed lens, the light that LED sends by lens lighting in the road surface.
Though the disclosed various street lamp LED of above-mentioned document can reach the purpose of effective luminous intensity distribution, but be used for the LED lens in the market in actual use because lens shaping area is less with respect to the angle of divergence of light source, and absorptivity is bigger, cause optical energy loss serious, in addition, the cost of manufacture height of lens, location in street lamp is difficult, must make the street lamp manufacturing process complicated more, difficulty of processing is big, the production cost height.
Summary of the invention
The objective of the invention is to, at being used at present the LED lens in the market in actual use because lens shaping area is less and absorptivity is bigger with respect to the angle of divergence of light source, cause optical energy loss serious, in addition, the cost of manufacture height of lens, the location in street lamp is difficult, must make the street lamp manufacturing process complicated more, difficulty of processing is big, and the practical problem that production cost is high provides a kind of efficient bar shaped reflection shield and the application in the LED street lamp thereof.
The object of the present invention is achieved like this: a kind of highly effective slot-shaped reflective cover, it is characterized in that: the elementary cell of slot-shaped reflective cover is the bar-shaped trough structure, center line is provided with the light source installing hole of two marshallings at least at the bottom of the bar-shaped trough, the both sides of bar-shaped trough are the side curved surface reflector of symmetry, two ends are the end face reflector of symmetry, wherein: side curved surface reflector is a quadric part, curved surface is opened outward by bottom land and is extended to bead, at the bottom of quadric starting point tangent line vertical channel, the flex point that the intercepting section is not crossed the outer Zhang Yanshen of quadratic surface; The end face reflector is opened outward by bottom land and is extended to bead, and its starting point and bottom land seamlessly transit.
In the present invention, the quadratic surface of described intercepting should be according to parabola, or circle, or the Changing Pattern of intercepting section is opened outward by bottom land and extended to bead in the ellipse.
In the present invention, efficient bar shaped reflection shield contains the elementary cell of a bar shaped reflection shield at least, and when adopting two above elementary cells, the bar-shaped trough of each elementary cell is parallel.
In the present invention, efficient bar shaped reflection shield adopts Merlon to make, and bottom land and each reflecting surface should plate reflective metal film.
In the present invention, described reflective metal film is to aluminize or reflective membrane that nickel plating or chromium plating form.
The application of above-mentioned highly effective slot-shaped reflective cover in the LED street lamp that the present invention relates to is characterized in that: the centre-to-centre spacing of described each light source installing hole that center line is arranged at the bottom of the bar-shaped trough should be greater than 22mm, and a LED lamp is installed in each light source installing hole.
In the application of the present invention in the LED street lamp, the spacing of each each light source installing hole is 22～50mm, and the spacing of each light source installing hole of mid portion is greater than the two-terminal led spacing of bottom land.
The present invention contains the efficient bar shaped reflection shield of two above elementary cells in the application of LED street lamp, each the light source position of mounting hole unanimity in the bar-shaped trough of each elementary cell is provided with a LED lamp in each light source installing hole.
The invention has the advantages that: because the both sides of slot-shaped reflective cover are the side curved surface reflector of symmetry, two ends are the end face reflector of symmetry, the light that can send the light source that is located at bottom land carries out effective shaping luminous intensity distribution, improve the effective lighting scope, distribution of light is even, efficiency of light energy utilization height, in the application of LED street lamp, owing to do not use lens, not only reduced the production cost of LED street lamp, and made the structure of light-emitting device compact more.Be suitable for very much the illumination of trunk roads, secondary distributor road, highway and branch road.
