The invention comprises a base plate (2) provided with a plurality of LEDs (1), the base plate (2) comprises at least two stages of bevel surfaces (21, 22, 23), the bevel surfaces (21, 22, 23) are inclined towards the horizontal plane by stages, and the LEDs (1) are arranged on the bevel surfaces (21, 22, 23). The invention can be widely applied to the outdoor lighting field.
Description
Technical field
The present invention relates to a kind of large power wide-angle LED road lamp.
Background technology
The energy consumption of lighting field accounts for 20% of whole electric energy, and that common illuminating lamp only has 30% electric energy to be used for is luminous, and all the other have changed into heat energy and have distributed to the external world.The heat that LED produces during because of its work is less, and luminous efficiency is higher, is regarded as cold light source.The LED street lamp is made up of substrate, lens and the cooling system etc. of band LED, compares with traditional incandescent lamp, fluorescent lamp, and its electric energy can reach more than 90%.Since it is born,, more and more be subjected to the attention of countries in the world with its efficient low-consume, energy-conserving and environment-protective, long characteristics of life-span.China is used for the electric power of street lighting present every year near 2,500 hundred million degree, and wherein if can have 1/3 to adopt the LED street lighting, annual just can the economize on electricity about 80,000,000,000 degree is equivalent to the annual electricity generating capacity in power station, Three Gorges basically.The LED illuminating lamp has become people's main R﹠D direction.
Existing LED street lamp all is that LED is installed on the planar substrates, and forms dot matrix on this substrate.Light that each LED sends forms a taper light beam, and the quantity of its coverage and the angle of divergence, irradiation distance and the LED of LED, power etc. are relevant.Widen irradiation distance, select the big LED of the angle of divergence for use, coverage can increase, but illumination can significantly fall sharply; If increase the quantity of substrate area and LED, coverage can only a little expansion, and cost can sharply raise.Adapt to market demand, will take into account illumination, coverage and cost, and existing LED street lamp can not take into account above-mentioned some.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and the large power wide-angle LED road lamp that a kind of coverage is big, illumination is strong, cost is low is provided.
The technical solution adopted in the present invention is: the present invention includes the substrate that is provided with several LED, described substrate comprises two-stage inclined-plane at least, and described inclined-plane ecto-entad tilts to horizontal plane step by step, and described inclined-plane is provided with several described LED.
Further, every grade of described inclined-plane has three at least, and with the described inclined-plane formation of the level of one-level one-level polygonal pyramid platform, described polygonal pyramid platform side is provided with described LED.
Further, described substrate comprises three grades of described polygonal pyramid platforms altogether.
Further, described polygonal pyramid platform is a tetragonous cone table, and every grade of described tetragonous cone table comprises two long inclined-planes and two short inclined-planes.
Further, the back side of described substrate is provided with radiator.
Further, described substrate is arranged in the metal shade, the part of described radiator and the back side of described substrate closely contact mutually connection, another part and described lampshade mutually closely contact be connected.
Further, described radiator comprises heat conduction backboard, several heat conduction muscle, described heat radiation backboard closely contacts connection mutually with the inner surface of described lampshade and the shape of the two is suitable, the top of described heat conduction muscle and described heat radiation backboard are fixedly connected, the bottom of described heat conduction muscle is provided with lower hem, and described lower hem closely contacts mutually with described inclined-planes at different levels respectively and connects.
The invention has the beneficial effects as follows: because substrate of the present invention comprises two-stage inclined-plane at least, described inclined-plane ecto-entad tilts to horizontal plane step by step, described inclined-plane is provided with several described LED, according to the street lamp height, the requirement of road illumination, select the great power LED of certain angle of divergence, and the different angle on each described inclined-plane on the default described substrate, draw the geometric optics schematic diagram of wide-angle LED road lamp of the present invention, when if the illumination patterns inequality occurring, again revise the inclination angle on corresponding inclined-plane, even until illumination patterns, illumination had not both had omission on the target road surface, divide overlapping only, be that the light that sends of several described LED is not overlapping to the full extent, make wide coverage, satisfy the illumination requirement of light simultaneously, so coverage of the present invention is big, illumination is strong, cost is low;
Because substrate of the present invention comprises three grades of described polygonal pyramid platforms altogether, so the present invention is easy to process;
Because polygonal pyramid platform of the present invention is a tetragonous cone table, every grade of described tetragonous cone table comprises two long inclined-planes and two short inclined-planes, generally speaking, the distance between adjacent two street lamps is often greater than width of roadway, and make described long inclined-plane be parallel to road surface main line when installing this moment; Then if the distance between adjacent two street lamps less than width of roadway, makes described long inclined-plane perpendicular to the road surface main line, so the present invention has guaranteed that to the full extent the range of exposures of street lamp is extensive when then installing;
Because the back side of substrate of the present invention is provided with radiator, so good heat dissipation effect of the present invention can guarantee the long-term temperature work of the present invention, long service life;
Because substrate of the present invention is arranged in the metal shade, the part of described radiator and the closely contact connection mutually of the back side of described substrate, another part and the closely contact connection mutually of described lampshade, the heat that LED produced when such structure made street lamp work conducts described metal shade through described substrate by described radiator, and be diffused in the external environment by described metal shade, LED is under the suitable operating temperature state all the time, the life-span reduction of having avoided LED at high temperature to work for a long time causing, so radiating effect of the present invention is better, can effectively increase the service life;
Because radiator of the present invention comprises heat conduction backboard, several heat conduction muscle, described heat radiation backboard closely contacts connection mutually with the inner surface of described lampshade and the shape of the two is suitable, the top of described heat conduction muscle and described heat radiation backboard are fixedly connected, the bottom of described heat conduction muscle is provided with lower hem, described lower hem closely contacts mutually with described inclined-planes at different levels respectively and connects, this structure makes that the contact area of described heat conduction muscle and described substrate and described heat radiation backboard is big, good effect of heat exchange is so radiating effect of the present invention is better.
