The LED street lamp is characterized in that: one end of the lamp box is provided with a mounting sleeve; the mounting sleeve is fixed with the lamp box into a whole; the LED light sources in the lamp box are arranged into a matrix; reflective cups are respectively arranged at the positions of the LED light sources; and each reflective cup which presents the shape of a concave tetragonous truncated cone consists of four triangular or inverted trapezoidal reflective plates. The integrated high-power LED street lamp has the following characteristics: a rectangular illumination zone can be formed, the long edge of the rectangular illumination zone is consistent with the direction of a street, and the short edge of the rectangular illumination zone is consistent with the width of the street, so that the street section where a lamp pole of the street lamp is located can be illuminated to the maximum degree; therefore, the LED street lamp can completely meet the requirement of street illumination; meanwhile, as radiating fins are arranged on the back surface of the lamp, the radiating area is increased and heat can be effectively radiated, so as to guarantee normal working of the LED light sources in the lamp.
Description
Technical field
The utility model relates to a kind of LED light fixture, is specifically related to a kind of integral type high-power LED street lamp fixture.
Background technology
Along with the development of great power LED manufacturing technology, the use of great power LED is increasingly extensive, particularly in the use in street lamp field, has multiple advantages such as energy-conservation, illumination height.High-power LED 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, but the Switching Power Supply volume is bigger, operating temperature range is narrow, especially maximum operating temperature usually can not be above 50 ℃, 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, brought great inconvenience for so again installation and waterproof, be unfavorable for the popularization of high-capacity LED illumination.Solve the heat dissipation problem of high-power LED street lamp fixture, and solve it inconvenience is installed, problem such as volume is excessive is the important topic and the difficult problem in this field.
Simultaneously, LED road lamp of the prior art adopts lens light gathering, can form circular illumination district one by one, and the circular illumination district 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
For an important topic and a difficult problem that solves above-mentioned this area, overcome the above-mentioned deficiency of prior art, the purpose of this utility model provides a kind of integral type 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 integral type high-power LED street lamp fixture, some led light sources are installed in the light fixture box, and the circuit board that carries this led light source, described led light source is connected with power supply circuits respectively, it is characterized in that, one end of described light fixture box is provided with mounting kit, and this mounting kit and described light fixture box are fixing as a whole; Described led light source is arranged in matrix in this light fixture box, and is 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.
The structure of described recessed four rib truncated cone shape reflectors is: constitute recessed four rib truncated cone shapes by sheet plastic, the inner face of these recessed four rib truncated cone shapes is provided with the metal reflective layer.Described metal reflective layer recommends to adopt aluminium lamination.
The present invention also has following prioritization scheme:
1, described led light source is arranged in matrix, can be matrix in a row, that embark on journey, also can be staggered matrix;
2, 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.
3, 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;
4, 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;
5, described boxlike light fixture and fin thereof are the overall structures that is made of casting aluminium material;
6, 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.
Reflector of the present utility model 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.
