Abstract
The utility model discloses an LED orientated light-condensing streetlamp, which comprises a lampshade, a plurality of LED beads and corresponding LED reflecting cups arrayed in the lampshade. The streetlamp is characterized in that the LED beads are arranged at the bottoms of the LED reflecting cups; and arc light-condensing surfaces are arranged on the side walls of the LED reflecting cups. The LED orientated light-condensing streetlamp is simple in structure, high in lighting efficiency, and environment-friendly, saves energy, and has good popularization value.
Description
Technical field
The utility model relates to lighting technical field, especially relates to a kind of LED street lamp.
Background technology
Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is large has caused the huge waste of the energy.Current, global environment is going from bad to worse, and each state is all at the development clean energy resource.And along with the rapid growth of national economy, China's energy supply and demand contradiction is outstanding day by day, the coming into existence situation of critical shortage of supply of electric power, and energy-conservation is present institute urgent problem.The LED street lamp, it is the high efficiency solid-state light source that the faint electric energy of usefulness that a kind of based semiconductor PN junction forms just can be luminous, under certain forward bias voltage and Injection Current, the electronics that injects the hole in P district and injection N district sends photon diffusing to active area by radiation recombination, electric energy is converted into luminous energy.What the LED street lamp was different from conventional high-pressure mercury lamp street lamp is, the light source of high-power LED street lamp adopts low-voltage DC supply, by the GaN based power type blue-ray LED efficient white light-emitting diodes synthetic with yellow fluorescent powder, have efficiently, the particular advantages such as safety, energy-saving and environmental protection, life-span length, fast response time, colour rendering index height.Number be CN201020216522.2 such as Chinese patent application, the utility model name is called a kind of LED street lamp, the upper lamp shade and the lower lamp shade that comprise mutual fastening, lower lamp shade is provided with aluminium base, the aluminium base front is fixed with a plurality of LED light emitting diodes of lining up array, and it is characterized in that: the aluminium base back side is fixed with heat dissipation copper pipe, is fixed with radiator on the heat dissipation copper pipe, described heat dissipation copper pipe length is greater than aluminium base, and the heat dissipation copper pipe two ends are equipped with the multi-disc fin.This patent structure has solved the heat dissipation technology difficult problem of great power LED effectively, guaranteed the service life of LED street lamp, but, because the LED lamp pearl quantity that the LED street lamp uses is more, the light that LED lamp pearl sends causes overlapping each other easily, not only wastes energy, and can be dazzling especially in the overlapping place of light, and the nonoverlapping place of light will seem secretly, affects light efficiency, also can cause harmful effect to human eye.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple in structure, and light is even, and the directed optically focused street lamp of energy-efficient LED.
The utility model is to adopt following technical solution to realize above-mentioned purpose: the directed optically focused street lamp of a kind of LED, comprise lampshade, be provided with a plurality of LED lamp pearls and the corresponding LED reflector of lining up array in the lampshade, it is characterized in that, described LED lamp pearl is arranged on the bottom of LED reflector, and the sidewall of LED reflector is provided with the arc caustic surface.
As further specifying of such scheme, described arc caustic surface is to the crooked curve slope that extends of its centerline direction.
The angle of inclination of described curve slope is 30-45 °, and the central angle that curve slope is corresponding is 90 ~ 150 °.
Described curve slope is provided with the cellular reflecting surface that a plurality of hexagon reflective surfaces form.
Described a plurality of LED reflector structure that is formed in one, its back side is provided with heat abstractor and power control.
Described a plurality of LED reflector is the reflector that arranges separately.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model is optimized improvement design to LED reflector shape, reaches the required requirement of street lamp, far firing range, and the effective light spot scope is large, allows LED light fixture light extraction efficiency promote, and reaches the energy-efficient purpose of LED light fixture.
2, the every LED lamp pearl in the utility model LED optically focused net battle array all is furnished with corresponding directed prefocus cup, and the inclined-plane of directed prefocus cup is set to arc, cellular reflective surface is set on the inclined-plane, the light that LED lamp pearl can be sent converges, therefore, can not superpose between the light of each lamp pearl, light is even.

Fig. 3 is arc caustic surface structural representation of the present utility model.
Description of reference numerals: 1, lampshade 2, LED lamp pearl 3, LED reflector 4, arc caustic surface 5, cellular reflecting surface.
The specific embodiment
As shown in Figure 1-Figure 3, the directed optically focused street lamp of a kind of LED of the utility model comprises lampshade 1, is provided with a plurality of LED lamp pearls 2 and the corresponding LED reflector 3 of lining up array in the lampshade 1, LED lamp pearl 2 is arranged on the bottom of LED reflector 3, and the sidewall of LED reflector 3 is provided with arc caustic surface 4.Arc caustic surface 4 is to the crooked curve slope that extends of its centerline direction.The angle of inclination of curve slope is 30-45 °, and the central angle that curve slope is corresponding is 90 ~ 150 °.Curve slope is provided with the cellular reflecting surface 5 that a plurality of hexagon reflective surfaces form, in the present embodiment, and a plurality of LED reflectors structure that is formed in one, its back side is provided with heat abstractor and power control.
Above-described only is preferred embodiment of the present utility model, should be pointed out that described a plurality of LED reflector can also be the reflector that arranges separately.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
