Abstract
The utility model disclose a LED street lamp which includes a lamp column (1), a street lamp shell (2), an external power supply, a rectifier and a light-controlled/time-controlled circuit both electrically connected with the power supply, LED light sources arranged in the street lamp shell (2), and a LED light source plate (5) in curved tile-shaped structure. The LED light sources are distributed in array on the light source plate (5). The utility model has the advantages of low energy consumption, reduced the installation and maintenance cost and long service life.
Description
Technical field
The utility model and lighting device more particularly, relate to the street lamp 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, power consumption is big, needs labor management, cost is very high.
The utility model content
The purpose of this utility model is that the energy consumption that exists in the above-mentioned prior art of solution is big, and the technical problem that cost is high proposes a kind of LED street lamp that adopts LED as light source.
The LED street lamp that the utility model proposes comprises lamppost, street lamp shell and external power supply, also comprise the rectifier that is connected with described power supply that is arranged in the street lamp shell and light-operated/time control circuit, led light source.
In an embodiment of the present utility model, also comprise a led light source plate, described 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 0.1～10 meter, and optimum state is 0.18 meter.The central angle D of cambered surface is 1～180 degree, is preferably 120 degree.
Compared with prior art, the utility model is reaching the light source of LED as road lighting lamp 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.In addition, the maintenance cost of LED street lamp is lower.
Description of drawings
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, power supply and is arranged on the interior light-operated/time switch of lamppost.Also comprise rectifier that is connected with power supply and the light source board 5 that is arranged in the street lamp shell 2, 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 0.1～10 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.
The led light source array is compared its structure and is had specific characteristics as the critical component in the system with other light sources.An independent led light source has stronger directionality as its light of illuminator, and this product uses many LED, and along certain cylinder curved surface composition array that evenly distributes, light peace different angles directive ground obtains a bright district along the road direction.The density of LED and the angle of distribution surface have determined the size of road surface brightness and bright areas.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, distance is 50 meters between the lamp stand, 8 to 12 meters of height, and 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.
As shown in Figure 5, circuit of the present utility model comprises: power supply, rectifier, light-operated/time switch circuit and load.Rectifier becomes the 220V alternating current of input into direct current (DC12V), through light-operated/time switch control, powers to LED.Light-operated/time switch can be controlled switching according to light, or time opening and closing.
The major advantage of led array light source solar street light is energy-conserving and environment-protective, and the LED lamp life-span is long, and light-operated switch does not need labor management, saves a large amount of energy.LED street lamp power consumption only is equivalent to 1/5th, common street lamp electricity consumption every day, 3 degree of common street lamp power consumption, but LED street lamp using electricity wisely in every year 800 degree.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.At present energy scarcity, to advocate under energy-conserving and environment-protective, the sustainable development overall situation, the use of LED Solar lamp has bright prospects.
