A kind of LED street lamp of band light sensor
Technical field
The present invention relates to a kind of LED street lamp, particularly relate to the LED street lamp of a kind of band light sensor, it is adaptable to outdoor lighting uses.
Background technology
Street lamp, is to show the light fixture that road provides illumination functions, refers to the light fixture in the illumination zone of road surface in traffic lighting, and infield is common in road one side, city or both sides.Nowadays along with the fast development in city, rhythm of life is more and more faster, the time of outdoor night life is more and more longer, in order to bring convenience to trip, street lamp is installed in road both sides, because irradiated area is big, scope extensively needs street lamp to have the mildness of high brightness and light, LED street lamp is arisen at the historic moment in this case, has that brightness is high, energy-conservation, length in service life, the advantage of light color adjustable replaceable.Street lamp is usually opens closedown in early morning between the lights, the time opened and closed is according to outdoor light luminance unified management by municipal officer, such as, 7 o'clock between the lights opens, 5 o'clock in early morning closes, this control mode is unreasonable, reason is as follows, annual four season light application time variant, the when of spring and summer sky, the time on daytime is the longest, the time needing street lighting is short, the when of autumn and winter sky, the time at night is the longest, the time needing street lighting is long, in order to not cause waste and meet civic demand, staff wants regular change to open, shut-in time, troublesome poeration, in-convenience in use, cause energy waste.
Summary of the invention
In order to solve the deficiency in background technology, it is an object of the invention to overcome the defect of background technology, it is provided that the LED street lamp of a kind of band light sensor, street lamp controls to be turned on and off according to the light of environment voluntarily, reasonable in design, easy to use, it is to avoid to cause energy waste.
For reaching above-mentioned purpose, the technical solution used in the present invention is: the LED street lamp of a kind of band light sensor, including LED lamp and the base of fixing described LED lamp, described LED lamp includes lamp housing, the bulb being located in described lamp housing and drives the control system controlling the work of described bulb, it is characterized in that: described envelope inner wall is provided with the light sensor for sensing light intensity protruding from described lamp housing outer wall, described light sensor is electrically connected with described control system.
In a preferred embodiment of the present invention, farther include to connect between described light sensor and described control system have signal condition unit.
In a preferred embodiment of the present invention, the outer wall farther including described lamp housing is circumferentially with solar energy thin plate, and described solar energy thin plate is electrically connected with described control system.
In a preferred embodiment of the present invention, farther include described base and be provided with power interface.
In a preferred embodiment of the present invention, farther include the most threaded lamp stand having hollow between described LED lamp and described base, in described lamp stand, be provided with winding displacement groove.
In a preferred embodiment of the present invention, farther including described base and be provided with installation portion, described installation portion is provided with installing hole.
The invention have benefit that: the LED street lamp of a kind of band light sensor of the present invention, control system controls being turned on and off of street lamp voluntarily by the light intensity that light sensor senses, reasonable in design, easy to use, it is to avoid to cause energy waste.Meanwhile, the outer wall at lamp housing is circumferentially with solar energy thin plate, utilizes solar energy to street lamp power supply, road lamp power supply, can reduce the consumption of electric energy.

Detailed description of the invention
In order to make those skilled in the art be more fully understood that the present invention program, and it is understandable to enable the above-mentioned purpose of the present invention, feature and advantage to become apparent from, and below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, a kind of LED street lamp of band light sensor, base 4 including LED lamp 2 and fixing LED lamp 2, wherein, LED lamp 2 includes lamp housing 6, be located in lamp housing 6 bulb 8 and drive the control system 10 controlling bulb 8 work, being particular in that of the present invention is provided with the light sensor 12 for sensing light intensity protruding from lamp housing 6 outer wall on lamp housing 6 inwall, and light sensor 12 is electrically connected with control system 10.Control system 10 is sensed by light sensor 12 and the light intensity value fed back controls the opening and closing of bulb 8, specifically so control: the threshold values of a light intensity can be set when the initialization of control system 10, compared by light intensity value and the threshold values that light sensor 12 is fed back, less than controlling to open the on and off switch of bulb 8 during threshold values, more than controlling to close the on and off switch of bulb 8 during threshold values, reasonable in design, easy to use, it is to avoid to cause energy waste.
Connecting between light sensor 12 and control system 10 and have signal condition unit 14, what light sensor 12 gathered is light signal, needs to be converted into, by signal condition unit 14, voltage or the current signal that control system 10 identifies.
The outer wall of lamp housing 6 is circumferentially with solar energy thin plate 16, and solar energy thin plate 16 is electrically connected with control system 10, utilizes solar energy to provide electric power, Appropriate application solar energy to street lamp, reduces the consumption of non-renewable electric energy.
On base 4, it is provided with power interface 18 as the second power supply mode, does not has during the sun to ensure while saving the energy that street lamp normally works by external power supply to street lamp power supply, road lamp power supply.
Between LED lamp 2 and base 4, the most threaded lamp stand 20 having hollow, is provided with winding displacement groove 22 in lamp stand 20, and the control system 10 of LED street lamp is generally located in base 4, is worked by cloth line traffic control LED lamp 2 in winding displacement groove 22, connects up safer, attractive in appearance.
Base 4 is provided with installation portion 24, installs 24 and is provided with installing hole 26, by installing hole 26, whole road lamp is fixed on road both sides.
Above-described embodiment is the present invention preferably embodiment; but embodiments of the present invention are also not restricted by the embodiments; the change made under other any spirit without departing from the present invention and principle, modify, substitute, combine, simplify the substitute mode that all should be equivalence, within being included in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim is defined.
