Abstract
The invention relates to a secondary light distribution reflecting mirror of an LED street lamp, which is a combined reflecting mirror. Each LED lamp bead is provided with a small reflecting mirror; each small reflecting mirror is provided with four reflective surfaces; two reflective surfaces along a road direction form an angle of 120 degrees; the other two reflective surfaces vertical to the road direction form an angle of 90 degrees; each LED lamp bead is positioned at the center of each small reflecting mirror; and a coning angle of 120 degrees of each LED lamp bead is limited to form a trapezoid cone angle through the reflective surfaces of different angles and form a light distribution curve forming a rectangle along the road direction. Because the front of the LED lamp beads has no obstacles, the reflecting mirror reflects light illuminating the outside of a road surface to the road surface so as to improve the light intensity of the road surface. A plurality of LED lamp beads are provided with a plurality of small reflecting mirrors; and the plurality of small reflecting mirrors are connected together to form the combined reflecting mirror. The secondary light distribution reflecting mirror has the advantages of simple manufacturing process, low manufacturing cost, long service life, no light loss, convenient installation, no debugging and convenient popularization and application.
Description
Technical field
The invention belongs to LED street lamp application field, be specifically related in the secondary light-distribution of LED road lamp, realize the distribution curve flux that street lamp requires with numerous small reflectors that connect together.
Background technology
At present, the light efficiency of LED lamp pearl is widely used in street lamp up to 80-110LM/W.The once light-distribution that is used for street lamp LED lamp pearl is generally made 120 ° coning angle, and the distribution curve flux of many LED lamp pearl composition high-power LED street lamps formation is rounded, is used for road lighting and causes the luminous energy waste.The distribution curve flux that is used for road lighting is to be rectangle or ellipse along road direction, to make full use of the luminous energy of street lamp.Need carry out secondary light-distribution to LED lamp pearl in order to form rectangle or oval-shaped distribution curve flux, general method is to add numerous lens above LED lamp pearl, the light direction of compound lens, the light that numerous LED lamp pearls are shone on the road surface is rectangle or ellipse, because lens are wanted the luminous energy of loss more than 10%, though formed rectangle or oval-shaped distribution curve flux, the illumination on road surface has reduced on the contrary.In addition, compound lens generally is that optical plastic is cast, and precision is low, and the life-span is short, and long-life numerous glass combination lens are difficult to processing.
Summary of the invention
For the distribution curve flux of the street lamp that makes numerous LED lamp pearls is rectangle or oval, not loss luminous energy again, the present invention has designed a kind of facetted mirrors, each LED lamp pearl is joined a small reflector, small reflector has 4 reflective surfaces, 2 reflective surfaces along road direction are hexagonal angle, 2 reflective surfaces of vertical road direction are 90 ° of angles, LED lamp pearl is positioned at the central authorities of small reflector, by the reflective surface of the different angles coning angle with 120 ° on LED lamp pearl, is constrained to trapezoidal cone angle, formation is along the road direction distribution curve flux that is rectangle, because without hindrance block material before the LED lamp pearl, the light that speculum will shine outside the road surface reflexes on the road surface, has improved the brightness on road surface.Numerous LED lamp pearls are furnished with numerous small reflectors, numerous small reflectors composition facetted mirrors that connects together.
The technology used in the present invention method is: facetted mirrors adopts ABS plastic to cast, and reflecting surface adopts the method for electroless plating or vacuum plating to plate layer of aluminum on reflecting surface or chromium forms mirror reflection surface.Manufacturing process of the present invention is simple, low cost of manufacture, and long service life, unglazed loss, easy for installation, need not debug, easy to utilize.
