Description

The LED solar street light

Technical field

The utility model and a kind of solar street light more particularly, relate to the solar street light of a kind of LED of employing as light source.

Background technology

The normal in the market street lamp that adopts is high-low pressure sodium vapor lamp, metal halid lamp or electricity-saving lamp, its light source power from tens watts to several hectowatts, its shortcoming is that power consumption is big, installing engineering expense and maintenance cost height.Recently solar street light day by day more sees, but, because present solar street light adopts conventional light source more, power consumption is big, for reaching normal lighting hours and brightness of illumination, all there are high requirement area and sunshine-duration to solar panel in the street lamp, cause present solar street light production cost height, are difficult to carry out.

Along with the raising of LED technology level, adopt led light source to become possibility as illuminations.Reaching under the situation of same brightness, the LED power consumption be sodium vapor lamp 1/5th in addition also to economize on electricity 80% than electricity-saving lamp, its life-span reaches 100,000 hours, is more than ten times of other lamp life-span; But because the illuminator of single led light source has stronger directionality, and street lighting requires to have the large-scale light source of large tracts of land to cover, thereby the LED technology is applied to become on the street lamp need waits the technical problem that solves.

The utility model content

The purpose of this utility model is to solve above-mentioned problems of the prior art, proposes a kind of LED solar street light that adopts LED as light source.

The LED solar street light that the utility model proposes comprises lamppost, street lamp shell, lampshade, solar panel, battery and control module.Also comprise the light source board in street lamp shell and the lampshade of being arranged on that is connected with described control module, this light source board is cambered surface watt shape structure, which is provided with the LED light emitting source that dot matrix is arranged.

The scope of the cambered surface radius R of described light source board is 0.01～10 meter, and optimum state is 0.18 meter.The central angle D of cambered surface is 1～180 degree, is preferably 120 degree.

The utility model is arranged in LED light emitting source dot matrix on the light source board that is cambered surface watt shape structure, and light peace different angles directive ground obtains a bright district along the road direction.By the density of adjusting LED and the size that light source board cambered surface central angle can obtain brightness of required road surface and bright areas.The LED lamp adopts solar powered, energy-conserving and environment-protective, and the LED lamp life-span is long, and light-operated switch does not need labor management.And can independently construct, need not bury cable underground, reduced operating expenses.Life-span length and automatic switch are again big advantages of LED lamp, without labor management, do not worry that light source damages, and has saved manpower and maintenance cost.The LED solar street light is a kind of desirable light source.

Below in conjunction with drawings and Examples the utility model is elaborated, wherein:

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is the cut-away illustration of the utility model light fixture;

Fig. 3 A, Fig. 3 B, Fig. 3 C are respectively cutaway view, the Left elevation and bottom views of the utility model light source board;

Fig. 4 is the schematic diagram of the utility model radiation of light source area;

Fig. 5 is the utility model circuit working theory diagram.

The specific embodiment

As illustrated in figs. 1 and 2, the utility model comprises lamppost 1, street lamp shell 2, lampshade 3, solar panel 4, battery and control module.Also comprise the light source board 5 in street lamp shell 2 and the lampshade 3 of being arranged on that is electrically connected with this control module, this light source board 5 is cambered surface watt shape structure, and raised surface is provided with the LED light emitting source that dot matrix is arranged.

In an embodiment of the present utility model, be fixed with the high perspex lampshade 3 of cambered surface below the street lamp shell 2, shell 2 forms hermetically-sealed construction with lampshade 3, and light source board 5 is installed in the sealing structure, and the lampshade 3 that the light that the LED on it sends passes high perspex lamp 2 illuminates the road surface.

Shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, be arranged with a plurality of LED on the light source board 5 of the present utility model, along the cambered surface LED light source consisting array that evenly distributes.The central angle D of light source board cambered surface can be arranged in 1～180 ° of scope, and cambered surface radius can be 0.01～10 meter range regulation.In this embodiment, used 460 LED altogether, divided 20 row to arrange, the density of LED dot matrix can be fixed according to brightness requirement, the high reticular density height of brightness requirement, on the contrary reticular density is low.Cambered surface radius R is 0.18 meter; The central angle D of cambered surface is 120 degree.

Fig. 4 is that the utility model light source is radiated at the schematic diagram on the road.Wherein the camber line central angle of light source board cambered surface is 120 degree.In this example, 50 meters of distances, 8 to 12 meters of height between the lamp stand, brightness does not have the direct light zone to be covered by floodlight along 42 meters of road overlay length up between two street lamps.During installation, the axis of cambered surface becomes 70 degree left and right sides angles with the road surface, and when the LED lamp was bright, light obtained an optical illumination clear zone along the road direction by different angles directive ground.The camber line central angle of the density of LED and light source board cambered surface has determined the size of road surface brightness and bright areas.

As shown in Figure 5, comprise in the described control module: be provided with micro computer, internal clock circuit (clock chip), the duty indicating circuit, light-operated/the time switch circuit of the control circuit that overcharges, overdischarge control circuit, also be provided with power circuit simultaneously into this module for power supply.This control module is electrically connected with solar panel, battery and load.Also be provided with an anti-reverse charge road between solar panel and the battery.

The electric current that solar panel produces is through anti-reverse charge road input battery, the battery stores energy, when charge in batteries voltage reaches certain numerical value, the anti-overcharge control circuit of microcomputerized control is cut off charging current, stop charge in batteries, preventing from battery overcharged influences battery service life; When the storage battery power supply undertension, microcomputerized control overdischarge control circuit is cut off the discharge current of battery, influences battery service life to prevent the battery over-discharge.Anti-reverse charge road electricity can prevent that battery current is from the charging circuit adverse current.Battery is electrically connected a micro computer working power, is used for micro computer is powered, and is provided with the duty indicating circuit in the micro computer, is used for the display system duty.On solar panel, also be connected with a lightning protection circuit, destroyed by thunderbolt with the whole supply line that prevents street lamp.

Experiment shows: the utility model adopts solar powered, does not need electrical source of power, saves a large amount of energy, can independently construct, and need not bury cable underground, has reduced operating expenses, and long service life.Every about 10,000 yuan of common street lamp costs, electricity consumption every day are no less than 3 degree, and energy charge was 7000 yuan in 10 years, and LED Solar lamp cost is 1.5 times of common street lamp cost.
