Abstract
The utility model relates to a centralized-type power supply system for LED (light-emitting diode) street lamps, comprising an AC/DC (alternating-current/direct-current) conversion circuit, wherein the AC/DC conversion circuit is connected with a low-voltage control switch; the low-voltage control switch is connected with a light-operated switch and an accumulator group respectively; the light-operated switch is connected with a plurality of the LED street lamps; and the accumulator group is connected with a solar cell panel array. The centralized-type power supply system for the LED street lamps disclosed by the utility model has the beneficial effects that the conversion circuit on each of the LED street lamps is centralized, thus greatly reducing difficulty in maintenance for the LED street lamps; and centralized management is performed on solar cell panels, thus facilitating the management while enhancing the own safety of the street lamps.
Description
Technical field
The utility model relates to a kind of centralized LED street lamp power supply, road lamp power supply system.
Background technology
Street lamp is the important component part of city illumination, what street lamp often adopted is high-pressure sodium lamp and LED street lamp, and maximum high-pressure sodium lamp that the road surface is used, the inner parts such as ballast are not easy to damage, the reason that major part does not work is that light source damages, and the mode of maintenance is as long as change light source.A skilled operator can the individual carry out high platform operation fully.But, the LED street lamp, inner parts are a lot, and except light source (chip), other various pieces are damaged and all can be caused chip not work.So, at the scene, can't conclude at once the reason that the LED street lamp damages.If the LED street lamp does not work, need to take the LED street lamp and transport factory back and carry out every detection.And present most of LED street lamp adopts solar energy and civil power to power simultaneously, and solar panels are excessive easily causes rocking of street lamp when running into strong wind, increase the security risk of street lamp, and solar panels that can be too small can not absorb solar energy again fully.
The utility model content
The purpose of this utility model is to provide a kind of centralized LED street lamp power supply, road lamp power supply system, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of centralized LED(light-emitting diode) street lamp power supply, road lamp power supply system comprises the AC/DC change-over circuit, and described AC/DC change-over circuit connects low-voltage control switch, and described low-voltage control switch connects light-operated switch, and described light-operated switch connects some LED street lamps; Described low-voltage control switch connects batteries, and described batteries connects solar panel array.
Further, described AC/DC change-over circuit connects civil power.
Further, all connect piezo-resistance between described LED street lamp and light-operated switch.
Further, described batteries is provided with the super-charge super-discharge protective circuit.
The beneficial effects of the utility model are: the utility model provides a kind of centralized LED street lamp power supply, road lamp power supply system, by the change-over circuit on single led street lamp is brought together, reduced greatly the difficulty on the LED source for street light maintenance, by solar panel is managed concentratedly, when having increased the safety of street lamp itself, also facilitated management.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structured flowchart of the described centralized LED street lamp power supply, road lamp power supply of the utility model embodiment system.
Embodiment
As shown in Figure 1, the described a kind of centralized LED street lamp power supply, road lamp power supply of the utility model embodiment system comprises the AC/DC change-over circuit, and described AC/DC change-over circuit connects low-voltage control switch, described low-voltage control switch connects light-operated switch, and described light-operated switch connects some LED street lamps; Described low-voltage control switch connects batteries, and described batteries connects solar panel array.Described AC/DC change-over circuit connects civil power.All connect piezo-resistance between described LED street lamp and light-operated switch.Described batteries is provided with the super-charge super-discharge protective circuit.
The utility model provides centralized LED street lamp power supply, road lamp power supply system with the LED street lamp of certain area as one group, current converter circuit and the cell panel of one group of LED street lamp are brought together, be that light fixture goes wrong so certainly when single led street lamp goes wrong, it is the problem of change-over circuit that whole zone goes wrong.Concentrate the solar panel of placing except for ease of maintenaince management, one of reason that the street lamp in a lot of cities can't adopt solar LED street lamp is exactly that high building is too many, solar panel can not receive sufficient sunlight, and concentrates the solar panel of placing only to need roof and a power supply box of a high building to solve.
Required AC/DC change-over circuit, low-voltage control switch, light-operated switch, piezo-resistance and the super-charge super-discharge protective circuit of LED street lamp power supply, road lamp power supply system provided by the utility model is for electrical domain commonly used, do not give unnecessary details one by one.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
Claims (4)
