LED lamp is regarded as 21 century lighting source because having the advantages such as environmental protection, energy-conservation, the life-span is long, replaces just gradually conventional light source and widely applies on various lightings.LED street lamp of the prior art is by comprising lamp stand, lamp bracket and lamp holder, lamp holder is comprised of shell and the light source module, the reflection shield that are arranged on shell, lamp holder is arranged on one end of lamp bracket, the LED street lamp of this structure is because lamp holder is fixed, cannot change street lamp installation, irradiating angle, and the range of exposures of street lamp is very little, on wider road surface, can only set up more street lamp to reach lighting requirement, this has increased the cost of road undoubtedly; And existing LED street lamp all adopts mains-supplied, is unfavorable for the realization of energy-conserving and environment-protective.
Utility model content
For above-mentioned deficiency of the prior art, the solar LED street lamp that a kind of random regulating irradiation angle is provided of the present utility model, has advantages of that safety, energy-saving and environmental protection, range of exposures are wide.
To achieve these goals, the technical solution adopted in the utility model is as follows:
The solar LED street lamp of capable of adjusting irradiation angle, comprise lamp stand, lamp bracket, lamp housing and light source module, also comprise lamp bracket cover, solar panel, battery and controller, described solar panel is arranged on the upper end of lamp stand, and battery is electrically connected to solar panel by controller; One end of lamp bracket is fixedly connected with and is positioned at the below of solar panel with lamp stand, the other end of lamp bracket is fixedly connected with one end of lamp bracket cover, and one end of lamp housing is fixed on lamp bracket and puts; Described light source module comprises the first light source module and secondary light source module, and the other end of one end of the first light source module and lamp bracket cover is hinged, and one end of the other end and secondary light source module is hinged, and the other end of secondary light source module and the other end of lamp housing are hinged; Described battery is electrically connected to the substrate on light source module by controller.
With respect to prior art, the utlity model has following beneficial effect:
Light source module is provided with to separate the first light source module and secondary light source module, and the first light source module and secondary light source module hinged, can regulate arbitrarily the irradiating angle of the first light source module and secondary light source module, and range of exposures is wider; Solar panel, battery and controller are set, and battery is electrically connected to solar panel by controller, daytime, by solar panel, change luminous energy into electric energy, and adopting battery by electrical power storage, in evening, battery can provide operating voltage for LED street lamp.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1: the solar LED street lamp of capable of adjusting irradiation angle, comprises lamp stand 1, lamp bracket 2, lamp bracket cover 3, lamp housing 4, light source module, solar panel 8, battery and controller.Solar panel 8 is arranged on the upper end of lamp stand 1, and battery and controller are embedded in underground or are arranged near in the casing of lamp stand 1, and battery is electrically connected to solar panel 8 by controller, and battery is electrically connected to light source module by controller.On daytime, solar panel 8 absorbs luminous energy, and is electric energy by transform light energy, by controller, is charge in batteries, and in evening, battery is given the power supply of LED lamp under the control of controller, and it is lighted.Battery can adopt lead-acid accumulator, and controller also has accumulator super-charge, Cross prevention, automatically detects battery electric energy (if when electric energy is inadequate, automatically switching to civil power), automatically detects the functions such as illumination.
One end of lamp bracket 2 is fixedly mounted on lamp stand 1 and is positioned at the below of solar panel 8, and the other end is set in the lamp bracket cover 3 of hollow structure, and lamp bracket 2 adopts screw to be fixedly connected with lamp bracket cover 3.One end of lamp housing 4 is fixed on lamp bracket cover 3, certainly, also can be fixed on lamp bracket 2.Light source module comprises the first light source module 71 and secondary light source module 72, the first light source module 71 and secondary light source module 72 include substrate, LED lamp pearl, reflection shield and radiator, LED lamp pearl is arranged on a side of the substrate in reflection shield, radiator is arranged on the opposite side of substrate, substrate is electrically connected to LED lamp power supply, LED lamp power supply is connected with storage battery by wire, and the first light source module 71 and secondary light source module 72 can arrange respectively separate power supply, also can share a power supply.The other end at lamp bracket cover 3 is provided with the first through hole, the first radiator 51 on the first light source module 71 is provided with the second through hole and third through-hole, the second radiator 52 on secondary light source module 72 is provided with fourth hole and fifth hole, is provided with six through hole corresponding with fifth hole on lamp housing 4; The first swivel pin, the second swivel pin, the 3rd swivel pin, the 4th swivel pin, the 5th swivel pin and the 6th swivel pin are corresponding to the first through hole, the second through hole, third through-hole, fourth hole, fifth hole and the 6th through hole respectively, between the first swivel pin and the second swivel pin, between the 3rd swivel pin and the 4th swivel pin, adopt respectively connecting rod 6 to be rotatably connected between the 5th swivel pin and the 6th swivel pin.Make the first light source module 71 and the secondary light source module 72 can randomly regulating irradiation angle, also increase the illumination range of street lamp simultaneously, reduce the quantity that LED street lamp is installed in unit section, saving cost.In order to add the adjustable range of the irradiating angle of university degree LED street lamp, fifth hole and the 6th through hole are all set to horizontally disposed bar hole, certainly, being horizontally disposed with is here comparatively speaking, and in the process of carrying out angle adjustment, this bar hole may be certain angle with horizontal direction.Adopt such setting, the 5th swivel pin and the 6th swivel pin can slide along bar hole, increase the adjustable extent of this Street Light Illumination angle, further increase range of exposures.For convenient after adjusting irradiating angle the fixing irradiating angle of street lamp, between lamp bracket cover and the first radiator, between the first radiator and the second radiator, be respectively equipped with lockable mechanism between the second radiator and lamp housing, after regulating light source module irradiation angle, can adopt lockable mechanism to lock, prevent that light source module from changing set angle under unartificial External Force Acting.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the present invention with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technical scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
