Solar LED street lamp
Technical field
The utility model belongs to the solar lighting technical field, especially relates to a kind of solar LED street lamp.
Background technology
In short supply day by day along with traditional energy, the application of solar energy will be more and more widely, and especially field of solar thermal power generation has developed into ripe rising industry in short time several years.Simultaneously, along with the development and progress of solar-photovoltaic technology, the solar energy lamp product is in the double dominant of environmental protection and energy saving, and the application of solar street light takes shape gradually.LED as a kind of energy-conservation, healthy light source scope of application more and more widely.
Solar LED street lamp is mainly by solar module part (comprising support), LED lamp holder, control cabinet (in controller, battery are arranged) and several parts formations of lamp stand.Existing solar LED street lamp generally adopts lead-acid accumulator, and the easy contaminated environment of this lead-acid accumulator, service life are shorter relatively, because volume and weight is bigger, transportation and installation cost are higher.In addition, general battery all is arranged on the bottom of lamp stand or is embedded in the underground storage battery dedicated case, because stube cable is longer, the cable pressure drop is bigger, is unfavorable for the charging and the discharge of battery, has influenced the service life and the efficient of battery.
Summary of the invention
The utility model mainly is at the above-mentioned deficiency of existing in prior technology, and a kind of solar LED street lamp that simple, energy-conserving and environment-protective, long service life are installed is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of solar LED street lamp, comprise battery, battery case, lamp stand, solar panels and LED lamp, described battery case is fixed on the middle part or the top of lamp stand, described battery is fixed on battery case inside, be connected by cable between solar panels and the battery, be connected by cable between LED lamp and the battery.
As preferably, described battery case is a kind of in circle, hexagon, triangle, quincunx, the square or rectangular.
As preferably, described battery case is evenly distributed around lamp stand one circle.More preferably, described battery case is provided with 2-6.Battery case is evenly distributed with the force balance that is beneficial to lamp stand around lamp stand, and a circle of lamp stand is established 2-6 battery case and can be constituted a ring-type battery case assembly, and is both beautiful and practical.
As preferably, described battery is a ferric phosphate lithium cell.Ferric phosphate lithium cell is the environmental protection battery, has characteristics such as light weight, high safety, long-life, green non-pollution.
As preferably, described battery case be fixed on lamp stand apart from ground 2~4 meters.Described battery case can be fixed on arbitrary height of lamp stand according to the requirement of reality, but prevents promptly that in the position at lamp stand 2~4 meters apart from ground battery case is stolen, makes the overall structure of solar LED street lamp more stable again.
As preferably, described solar panels are fixed on the top of lamp stand.Can make full use of luminous energy is not blocked.
As preferably, described battery case surface is provided with waterproof coating, and battery case is provided with the fan-shaped edge that Open Side Down.Fan-shaped edge can prevent effectively that rainwater from falling into battery case inside, simultaneously can exhaust and heat radiation.
Compare with existing LED street lamp, the utlity model has following characteristics:
1, battery case and battery are fixed on the middle part or the top of lamp stand, have shortened the distance of the interior battery of battery case and LED lamp and solar panels, and the cable pressure drop is less, has prolonged the service life of battery, has improved the service efficiency of LED lamp.
2, adopt novel ferric phosphate lithium cell,, reduced the frequency of maintenance of LED street lamp because it has characteristics such as light weight, high safety, long-life, green non-pollution.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the A portion enlarged diagram of Fig. 1.
Label declaration: battery 1, battery case 2, lamp stand 3, solar panels 4, LED lamp 5, fan-shaped along 6.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Solar LED street lamp shown in Figure of description 1,2, form by battery 1, battery case 2, lamp stand 3, solar panels 4 and LED lamp 5, LED lamp 5 is fixed on the crooked end of lamp stand 3, solar panels 4 are fixed on the top of lamp stand 3, battery case 2 is fixed on the middle and upper part of lamp stand 3, apart from the position at lamp stand top 1/3rd, be connected by cable between solar panels 4 and the battery 1, be connected by cable between LED lamp 5 and the battery 1.Battery case 2 is provided with 3, is provided with 1,3 battery case of a battery in each battery case and is evenly distributed around lamp stand 3 one circles; Battery case 2 surface-coated one deck waterproof coatings, battery case 2 is provided with fan-shaped along 6 that Open Side Down.Battery 1 is a ferric phosphate lithium cell.
Battery case is a rectangle in the present embodiment, can certainly according to circumstances be designed to circle, hexagon, triangle, quincunx or square.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.As, battery case is fixed on lamp stand all can realize purpose of the present invention in 2~3.5 meters apart from ground.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
