Description
Technical field
The present invention relates to a kind of LED light fixture, be specifically related to a kind of high-power LED street lamp fixture.
Background technology
Great power LED (referring to that single LEDs power is not less than 1W) illumination is the revolutionary technology of at present universally acknowledged replacement traditional lighting, and the high-capacity LED light fixture can be used as the regeneration product of current large power road lamp, floodlight.But, also have many technical problems to influence its promotion and application because this new technology application time is not long.Relatively Tu Chu technical difficulty has: a large amount of heating problems of high pressure mains-supplied and power supply and LED.LED high power illumination light fixture adopts low-voltage DC supply usually, modal form adopts voltage-stabilizing switch power source to connect constant-current control circuit more exactly, this method circuit form is simple, especially for the light fixture producer that lacks the design of electronics constant current technology, is a kind of simple method that realizes easily.But the Switching Power Supply volume is bigger, operating temperature range is narrow, especially maximum operating temperature can not surpass 50 ℃ (also the arriving 60 ℃ of military project level) usually, and the reliable operating temperature of LED need be below 70 ℃, so just limited power supply has been installed in the luminaire body, promptly enable to be installed in the lamp body, power is big (generally being no more than 40W) too, therefore the common above high-capacity LED light fixture of 100W, usually adopt plug-in Switching Power Supply, bring great inconvenience for so again installation and waterproof, be unfavorable for the popularization of high-capacity LED illumination.
The illumination zone of street lamp the best is a rectangle light field, and the long limit of this rectangle light field is consistent with the link length direction, and minor face is consistent with the width of road.And the illumination light field of the LED road lamp of the most employing of prior art lens light gathering is a circular illumination district, and the light field that two adjacent street lamps form can't be connected, and causes dark space one by one on the road, greatly reduces uniformity index; And at the width of road, there are a large amount of invalid illumination zones again in two edges in circular illumination district, cause waste.This circular illumination district is that the structure by the road lamp of prior art causes; So need improve to the structure of road lamp.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the purpose of this invention is to provide a kind of high-power LED street lamp fixture.This light fixture can solve the heat dissipation problem of LED and power supply preferably, can make the power of high-capacity LED light fixture in normal size reach 200W or higher, thereby reach the function of real practicality; And can make its illumination zone form a rectangle light field, and the long limit of this rectangle light field is consistent with the link length direction, and minor face is consistent with the width of road, satisfies the specification requirement of street lighting.
The technical scheme of finishing the foregoing invention task is: a kind of high-power LED street lamp fixture, constitute by boxlike light fixture and mounting kit fixed connection, be provided with some led light sources in the front of this boxlike light fixture, and the circuit board of carrying led light source, led light source is connected with power supply circuits respectively, it is characterized in that, described led light source is arranged in matrix, and be provided with reflector at each led light source place, the recessed four rib truncated cone shape reflectors that this reflector is made up of four triangles or the trapezoidal reflector that falls, wherein the angle on two of reflector width reflectors and plane, led light source place is greater than two reflectors of length direction and the angle on plane, led light source place; The back side of described boxlike light fixture is provided with some fin.
The front of boxlike light fixture is meant the one side of sending illumination described in the above scheme;
The length direction of boxlike light fixture described in the above scheme is meant the direction of the street lamp post extended line on the light fixture, promptly vertical with trend of road direction;
The width of boxlike light fixture described in the above scheme is a direction vertical with above-mentioned length direction on the boxlike light fixture, promptly consistent with trend of road direction;
But should describe with the physical length of concrete light fixture irrelevant with width, that is, and the size of the what is called " width " of concrete light fixture can less than, more than or equal to the size of what is called " length direction ".
The present invention has following prioritization scheme:
1, the power supply circuits of described led light source can be the power supply circuits that adopt the 220V civil power; It also can be the low pressure AC-DC Circuit; Can also be the power supply circuits that the solar energy of solar panel is set;
2, described led light source is arranged in matrix, can be matrix in a row, that embark on journey, also can be staggered matrix;
3, each led light source in the matrix adopts in the row in parallelly, and the mode of connecting between row and the row is connected; Perhaps adopt series connection in the row, the mode of parallel connection is connected between row and the row; Perhaps whole connected modes of connecting.
4, the mounting kit on the described light fixture is the mounting kit that adopts the light fixture flat board to constitute with bolting Ω shape ambulatory splint mode down; This mounting kit is used for the fixing of lamp body and street lamp post;
5,, be provided with printing opacity safety glass backplate in the front of light fixture;
6, at the position of described boxlike light fixture near mounting kit, be provided with power storehouse, the power supply circuits of led light source can be installed in this power storehouse; Also can place the light fixture outside according to circumstances;
7, the back side of boxlike light fixture is provided with some installing holes;
8, described boxlike light fixture and fin thereof are the overall structures that is made of casting aluminium material;
9, the recessed four rib truncated cone shape reflectors formed of four triangles on described each led light source or the trapezoidal reflector of falling are connected to each other and constitute reflector plate into integral body.
The reflector of light fixture of the present invention adopts four triangles or falls the recessed four rib truncated cone shape reflectors of trapezoidal reflector composition, its reflecting effect can form a rectangular illumination district, and because the angle on two reflectors of width and plane, led light source place is greater than two reflectors of length direction and the angle on plane, led light source place, so the long limit in this rectangular illumination district is consistent with trend of road; The minor face in this rectangular illumination district is consistent with the width of road; Can farthest illuminate the highway section at this street lamp post place, meet the needs of road lighting fully.Simultaneously, because be provided with fin at the light fixture back side, increased area of dissipation, distribute heat effectively guarantees the operate as normal of led light source in the light fixture.
