The specific embodiment
In order to make the technical problem that will solve of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, the floodlight of present embodiment comprises light source 100, electrical box 110, reflector 130 and Transparent Parts 140.Be provided with current treatment device and lamp socket in the electrical box 110.The size of light source 100 and the size of reflector coupling, the centre of luminescence of light source is housed in reflector inside, avoids the light direct projection eyes of light source 100.Wherein, light source 100 has center line or axes O.Light source 100 is electrically connected with the lamp socket of electrical box 110.Reflector 130 is fixed on the electrical box 110.Transparent Parts 140 is tightly connected with electrical box 110, and light source 100 is sealed.As shown in Figure 1, this Transparent Parts 140 is extended reflector 130 downwards along axes O, and its lower end is the outside with reflector 130.As illustrated in fig. 1 and 2, the top of reflector 130 is provided with the through hole 135 that is used to install light source.Light source 100 stretches out downwards from this through hole 135.2 screws 136 on the roof of reflector, reflector are fixed on the bottom of electrical box 110 by this screw 136.Certainly, a plurality of screws 136 can be set also, to realize more firm connection.Here, the structure and the annexation of light source 100, electrical box 110 and Transparent Parts 140 belong to prior art, are not described in detail at this.
Shown in Fig. 2 and 3, the reflector 130 of present embodiment is bowl-shape under shed, and the inner surface of reflector 130 is a reflective surface, and this reflective surface is three sections reflective surfaces.Certainly, the invention is not restricted to this, also optically focused degree and irradiation height that can be required according to floodlight is provided with the multistage reflective surface.In addition, each reflective surface all adopts electrochemical polishing to handle to improve reflecting effect.
Particularly, reflective surface is the surface of revolution of specific curves around the axes O rotation formation of light source 100.Should be understood that the surface of revolution is meant the curved surface that is formed around fixed axis revolution by straight edge line or bent bus.In the present embodiment, the reflective surface of reflector 130 is the surface of revolution.The centre of gyration line of reflective surface overlaps with the axes O of light source 100.Wherein, reflective surface comprises three sections reflective surfaces, that is: second reflective surface 132 that extends downwards away from axes O with vertically disposed first reflective surface 131 of axes O, from first reflective surface 131 and the 3rd reflective surface 133 that extends downwards away from axes O from second reflective surface 132.The bottom of the 3rd reflective surface 133 is provided with the crimping 134 of outside coiling.The second angle β between the first angle α between first reflective surface 131 and second reflective surface 132 and second reflective surface 132 and the 3rd reflective surface 133 is the obtuse angle.That is, the first angle α and the second angle β should be greater than 90 ° and less than 180 °.Preferably, the first angle α between first reflective surface 131 and second reflective surface 132 is between 150 °～155 °; And the second angle β between second reflective surface 132 and the 3rd reflective surface 133 is between 110 °～120 °.In the floodlight of the present invention, the length of second reflective surface 132 on axis direction is 25.2mm, and the length of the 3rd reflective surface 133 on axis direction is 82.0mm.In addition, as shown in Figure 2, the opening angle γ of reflector 130 is between 45 °～55 °.That is the twice that constitutes the rotation bus of the 3rd reflective surface 133 and the angle between the axes O is between 45 °～55 °.
It is emphasized that in the present embodiment that the first angle α and the second angle β set for the situation of 5m according to the irradiation height.The shape of reflective surface should be determined according to factors such as optically focused degree, irradiation brightness, distribution curve fluxs.Herein, the implication of " distribution curve flux " is: the luminous intensity with vector representation light fixture all directions constitutes a sealing light intensity body, draws the sealing intersection of light intensity body quilt by the plane cut of vertical axis with polar form.Distribution curve flux comprises sleeve configuration, flower type, circle, petal etc.Therefore, in case of necessity, reflective surface also can comprise the 4th reflective surface and downward successively the 5th reflective surface, the 6th reflective surface that extends that extends away from axes O from the 3rd reflective surface 133 downwards ...
In addition, in order to strengthen the antisepsis of reflector, be coated with the outdoor powder of the pure polyester that is useful on anticorrosion antiacid alkali on the outer surface of reflector 130.This open air powder belongs to pure polyester powder, and it is similar to paint, and uvioresistant is stronger, and color is fugitive color not, can keep bright-coloured beautiful for a long time.Moreover in order to improve the reflective function of floodlight, the inner surface of reflector 130 is the electrochemical polishing face.
As mentioned above, reflector of the present invention is bowl-shape under shed.The reflective surface of reflector 130 is the surface of revolution.The centre of gyration line of reflective surface overlaps with the axes O of light source 100.Wherein, reflective surface comprises second reflective surface 132 that extends downwards away from axes O with vertically disposed first reflective surface 131 of axes O, from first reflective surface 131 and the 3rd reflective surface 133 that extends away from axes O from second reflective surface 132 downwards.The bottom of the 3rd reflective surface 133 is provided with the crimping 134 of outside coiling.In the present embodiment, the first angle α between first reflective surface 131 and second reflective surface 132 is between 150 °～155 °; The second angle β between second reflective surface 132 and the 3rd reflective surface 133 is between 110 °～120 °.First angle and second angle are determined according to the distribution curve flux of light fixture.This structure is provided with and is beneficial to the light refraction performance that strengthens the reflector inner surface, makes irradiation light softer, even.Can effectively alleviate the anti-dazzle problem of light fixture, prevent that eyes are subjected to the dazzle irradiation, influence eye health.
In addition, in the floodlight of the present invention, the inner surface of reflector can be the electrochemical polishing face, to improve the reflective function of floodlight.In addition, in the floodlight of the present invention, reflective surface also can comprise the 4th reflective surface and downward successively the 5th reflective surface, the 6th reflective surface that extends that extends away from axis from the 3rd reflective surface downwards according to optically focused degree, irradiation height or the distribution curve flux of light fixture ...Like this, just can satisfy the needs of optically focused degree, irradiation height or the distribution curve flux of various light fixtures, strengthen the light refraction performance of reflector inner surface, improve optically focused degree and brightness that it shines the orientation, effectively alleviate the anti-dazzle problem of light fixture.
Although this paper has described many embodiment, those skilled in the art will appreciate that and under the situation that does not break away from the spirit that is defined by the following claims and scope thereof, to make other modification or change.
