Abstract
The utility model discloses an LED streetlamp with large irradiation area, which comprises an integral heat radiator, a light transmission mirror and two LED boards, wherein, each LED board consists of a plurality of LED and a fixed circuit board which electrically connects the LED; the integral heat radiator is of a V-shaped structure with the angle of 150 to 180 degrees, and the bottom surface of the integral heat radiator is provided with an installation groove of the LED boards and the light transmission mirror, and the two LED boards are installed inside the installation rove of the integral heat radiator at an angle of 180 to 210 degrees, and the light transmission mirror is installed inside the installation groove of the light transmission mirror on the bottom surface of the integral heat radiator. The LED streetlamp has good heat radiation effect, high light emitting rate, large irradiation area and homogeneous light brightness under the situation that the area of the LED board and the quantity of the LED are identical; moreover, the brightness is higher than the national requirements on the brightness of the streetlamp. The LED streetlamp reduces the cost.
Description
One, technical field:
The utility model belongs to a kind of LED street lamp.
Two, background technology:
What transitional street lamps was used is mercury lamp, sodium vapor lamp, Metal halogen lamp or electricity-saving lamp, and its energy source is in the alternating current of 220v, and not only power consumption is big, and service life is short, and the maintenance cost height is unfavorable for energy-saving and cost-reducing and environmental protection.Therefore, substitute the revolution that conventional lamp has become lighting field with the LED light fixture.
Existing LED street lamp generally is after arranging a plurality of LED on the wiring board, be covered with externally again that a plane transmissive mirror forms, light is overlapped to concentrate by the light of a plurality of LED and forms in the middle of it, its brightness is concentrated, and intermediate luminance is too high, and both sides brightness is low, irradiated area is little, in order to increase irradiated area, can only increase the number of the area and the LED of whole light fixture, the cost of light fixture is also corresponding have been increased much.Its radiating effect is poor, and light extraction efficiency is low.
Three, summary of the invention:
The purpose of this utility model is exactly to solve now with the problems referred to above that exist in the technology, provides a kind of irradiated area big, and cost is relatively low, good heat dissipation effect, the LED street lamp that the irradiated area that light extraction efficiency is high is big.
For finishing the purpose of this utility model, its technical solution is: the LED street lamp that a kind of irradiated area is big, it comprises an integral heat sink device, a transmissive mirror and two led boards, and each led board is by a plurality of LED, fixing and the wiring board that each LED is electrically connected formed; The integral heat sink device is that angle is 150 °-180 ° a V font structure, have the mounting groove of led board and transmissive mirror on its bottom surface, two led boards are installed in according to 180 ° of-210 ° of angles in the mounting groove of led board of integral heat sink device, and transmissive mirror is installed in the mounting groove of transmissive mirror of integral heat sink device.
The wiring board of above-mentioned described two led boards of the present utility model is the common line plate, and the integral heat sink device is the aluminum metal part of band heat radiation wing, and two led boards are adhesively fixed on the integral heat sink device by one deck insulating heat-conductive silica gel.
The wiring board of above-mentioned described two led boards of the present utility model is an aluminum-based circuit board, the integral heat sink device is the aluminum metal part of band heat radiation wing, two led boards are directly installed in the mounting groove of led board of integral heat sink device, perhaps are adhesively fixed on the integral heat sink device by one deck insulating heat-conductive silica gel.
Above-mentioned described LED is a high-power LED.
Because the utility model is made the integral heat sink device with radiator, its good heat dissipation effect, light extraction efficiency height.Two led boards are installed in according to 180 ° of-210 ° of angles in the mounting groove of led board of integral heat sink device, under the identical situation identical of area of led board with the LED number, it is big that its rising angle becomes, the overlapping number of times of middle light reduces, brightness reduces in the middle of it, and the brightness on both sides is then extended, and it is big that irradiated area becomes, brightness becomes evenly, and its illuminance is higher than the satisfy the need requirement of lamp illuminance of country.The corresponding cost that reduces the LED street lamp of the utility model.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the AA amplification view of Fig. 1.
Five, the specific embodiment:
As depicted in figs. 1 and 2, present embodiment comprises an integral heat sink device, a transmissive mirror 3 and two led boards.Each led board is by a plurality of great power LEDs 4, fixing and the common line plate 2 that each LED4 is electrically connected formed.The integral heat sink device is the aluminum metal part 1 of band heat radiation wing 7, and it is shaped as angle is 160 ° V font structure, has the mounting groove 8 and 9 of led board and transmissive mirror 3 on its bottom surface.Two led boards are adhesively fixed on according to 200 ° of angles by one deck insulating heat-conductive silica gel 5 in the mounting groove 8 of led board of integral heat sink device.Transmissive mirror 3 is installed in the mounting groove 9 of transmissive mirror of integral heat sink device.6 for being installed in the mounting rod on the electric pole.
