Abstract
The utility model discloses a broad illumination LED street lamp comprising LED lamp groups, wherein each LED lamp group comprises LED chips and lenses enlarging the illumination angles of the LED chips. The LED street lamp also comprises a corner joint which is of a rotatable structure and connects the two LED lamp groups. By adopting the corner joint, the light emitting angle and the elevation angle of each LED group can be adjusted; therefore the irradiation range along the road direction can be adjusted so that the luminance uniformity of luminous spots on road surfaces can be increased.
Description
Technical field
The present invention relates to lighting technical field, relate in particular to a kind of LED street lamp.
Background technology
Existing LED lamp post structure scheme is more, and most designs are arranged LED lamp group based on flat structure at dull and stereotyped upper edge plate face, and this flat board is whole aluminium die casting or an aluminium section bar simple in structure.Though the mechanical processing technique of plank frame is fairly simple, but because the irradiating angle of LED lamp itself is narrow, therefore it is desired to reach national street lamp standard (in July, 2007 enforcements), and the illumination zone when high 12 meters of lamp is that the rectangular light spot of 12m * 33m requires just to be difficult to realization.
Although the design of some LED street lamp increases illumination angle and produces rectangular light spot with lens, because common lens generally increase illumination angle to 90 degree, so still be difficult to reach the standard-required of the rectangular light spot of regulation.
The applicant's a patent (patent name: LED street lamp, the patent No.: CN.200820202195.8), wherein introduced a kind of LED street lamp, the mounting base of this LED lamp group is the inclined-plane of two intersections, LED lamp group all is installed, like this under the situation that the illumination angle of LED lamp group is fixed, owing to there is the inclined-plane that intersects on each inclined-plane, make the irradiating angle of LED street lamp integral body strengthen, thereby illumination zone can be up to state standards.But the irradiating angle of this patent can not be adjusted, and when the lamp height changed, the brightness uniformity of illumination hot spot can change.
The utility model content
Technical problem to be solved in the utility model provides the wide and adjustable LED street lamp of irradiating angle of a kind of illumination zone.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of wide illumination LED street lamp, has LED lamp group, this LED lamp group comprises led chip and enlarges the lens of led chip irradiating angle, this LED street lamp also comprises Corner Link, and this Corner Link is turntable and connects two LED lamp groups.Adopt Corner Link can regulate the rising angle and the elevation angle of each LED lamp group, thereby can improve the brightness uniformity of road surface hot spot in direction adjusted range of exposures along road.
LED lamp group comprises housing, and hull outside has fin, and enclosure interior is equipped with the auxilliary arranging device of auxiliary heat dissipation.
The enclosure interior of LED lamp group also is equipped with the power supply that can regulate by the led chip electric current.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the wide illumination LED street lamp of the utility model, two LED lamp groups 6 are arranged, this LED lamp group 6 comprises led chip 1 and enlarges the lens of led chip irradiating angle, fuse by Corner Link 5 between the LED lamp group 6, this Corner Link 5 is a turntable, can regulate two angles between the LED lamp group 6 by it.Adopt Corner Link can regulate the rising angle and the elevation angle of each LED lamp group, thereby can improve the brightness uniformity of road surface hot spot in direction adjusted range of exposures along road.
LED lamp group 6 comprises housing 2, and housing 2 outsides have fin 7, and the power supply 4 that can regulate by the led chip electric current is equipped with in housing 2 inside, and the auxilliary arranging device 3 of auxiliary heat dissipation also is housed, and this auxilliary arranging device 3 can be a fan.
Claims (3)
1. one kind wide illumination LED street lamp, has LED lamp group (6), described LED lamp group (6) comprises led chip (1) and enlarges the lens of led chip irradiating angle, it is characterized in that: also comprise Corner Link (5), described Corner Link (5) is for turntable and connect two LED lamp groups (6).
2. wide illumination LED street lamp according to claim 1 is characterized in that: described LED lamp group (6) comprises housing (2), and housing (2) outside has fin (7), and the auxilliary arranging device (3) of auxiliary heat dissipation is equipped with in housing (2) inside.
