Description
Technical field
The utility model relates to technical field of lamps, specifically, relates to a kind of adjustable-angle LED street lamp.
Background technology
The LED lamp is as new light source, because of characteristics such as it has that the life-span is long, light efficiency is high, radiationless, low energy consumption, has been widely used in outdoor illumination field, especially for the larger street lamp of electric consumption on lighting proportion.In the LED street lamp of prior art, each LED lamp pearl is all towards same direction, and the lighting angle of each LED lamp group in the LED street lamp is uncontrollable, can't regulate the illumination zone of LED street lamp, makes the illumination zone of LED street lamp be restricted.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of can be separately to each module adjusting angle, the wide adjustable-angle LED street lamp of illumination range.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of adjustable-angle LED street lamp, comprise the power supply room, light source chamber and the block that are linked in sequence successively, and an end of described power supply room is provided with mounting pipe, is provided with driving power in described power supply room; Described light source chamber comprises some LED module group units, each described LED module group unit comprises heat sink, post the LED module on described heat sink, described LED module comprises the LED lamp pearl that is attached to the aluminium base on described heat sink and is located at the some series connection on described aluminium base, some described LED modules are parallel-connected to described driving power, leave the interval between described heat sink, each described heat sink rotates and is installed on the crane span structure of described light source chamber both sides, also is provided with the bolt for fixing described heat sink on a described crane span structure of side.
Preferably, described heat sink is the aluminium section bar heat sink.
Preferably, be covered with lens on each described LED lamp pearl.
Preferably, also be provided with glass below described lens, described embedding glass is to described heat sink.
After having adopted technique scheme, the beneficial effects of the utility model are:
Because this adjustable-angle LED street lamp comprises power supply room, light source chamber and the block that is linked in sequence successively, an end of described power supply room is provided with mounting pipe, is provided with driving power in described power supply room; Described light source chamber comprises some LED module group units, each described LED module group unit comprises heat sink, post the LED module on described heat sink, described LED module comprises the LED lamp pearl that is attached to the aluminium base on described heat sink and is located at the some series connection on described aluminium base, some described LED modules are parallel-connected to described driving power, leave the interval between described heat sink, each described heat sink rotates and is installed on the crane span structure of described light source chamber both sides, also is provided with the bolt for fixing described heat sink on a described crane span structure of side.This adjustable-angle LED street lamp in use, according to using on-the-spot needs, can rotate separately every block of heat sink to suitable angle, drive every group of LED module and turn to suitable angle, then screw the bolt on a side crane span structure, heat sink is fixed, better regulated the lighting angle of LED lamp, make its illumination range wider, making between two street lamps does not have the dark space.In addition, each LED module is to work alone, and when one of them LED module breaks down, can not have influence on other LED module.Each module is furnished with a heat sink, and is equipped with distance between heat sink, and result of ventilating heat dissipation is good.
Because described heat sink is the aluminium section bar heat sink, can by changing the length of aluminium section bar heat sink, increase easily the quantity of LED module, thereby increase the power of this LED lamp.
Owing to being covered with lens on each described LED lamp pearl, the light that therefore LED lamp pearl is sent has carried out secondary light-distribution, has spread emission angle and scope, and making between two street lamps does not have the dark space.
