Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
Composition graphs 1 and Fig. 7, the reflective glare prevention LED wall lamp of one of the present embodiment, primarily of compositions such as shell 1, light-emitting plate 5, end cap 6, LED light source 3 and reflectors 4, end cap is arranged on shell 1 two ends, LED light source 3 is fixed on light source board 2, and light source board 2 and reflector 4 are fixed in shell 1, is fixed with light-emitting plate 5 at shell 1 top, this light-emitting plate 5 is glass plate, makes light source board 2 and reflector 4 be encapsulated in shell 1 inner.Shell 1, end cap 6 and light-emitting plate 5 mainly play the effect of heat radiation, support, protection, prevent waterlogged damage component in shell 1.
Composition graphs 1 and Fig. 2, the optical axis x of the LED light source 3 in the present embodiment is vertical with the central shaft y2 of reflector 4, and lamp optical axis y1 vertical enclosure 1 base plate of LED wall wash lamp, central shaft y2 is parallel with lamp optical axis y1.LED light source 3 is positioned on the intersection point O of optical axis x and central shaft y2, namely LED light source 3 is arranged on the sidewall of shell 1 inside, and LED light source 3 is positioned on central shaft y2.In the present embodiment, reflector 4 inner surface is reflective cambered surface 41, the intersection in the arbitrary cross section and reflective cambered surface 41 of crossing central shaft y2 is parabola, reflective cambered surface 41 is made to form a parabola, as everyone knows, collimation all penetrates by the light penetrated by its focal point after parabolic reflector, therefore make O point as parabolical focus, as shown in Figure 5, then the light that LED light source 3 projects in reflective cambered surface 41 is all collimated injection.In addition, the present embodiment is by laterally disposed for LED light source 3, major part light collimates injection after reflective cambered surface 41, instead of directly outgoing, make more light by parallel convergence, reduce the generation of dazzle, the more effective K value (the center light intensity values of the every kilolumen of light fixture) that improve wall lamp, thus improve wall lamp wash wall height.
In order to optimal design, definition optical axis x and face, central shaft y2 place are middle section, make reflector 4 symmetrical about middle section, then bright dipping evenly.When laterally disposed LED light source 3, LED light source 3 bottom is all arranged to retroreflective regions seem to obtain stronger brightness, but consider that the light intensity of fringe region is more weak, less on the K value impact of wall lamp, and unnecessary reflective areas can increase the bulk of light fixture greatly, therefore in the present embodiment, reflector 4 adopts the incomplete paraboloid structure after excising extraneous region.As shown in Figure 2 and Figure 3, the dual-side of reflective cambered surface 41 parallels, the top margin of reflective cambered surface 41 is top camber line 412, corresponding to this top camber line 412, central angle is α, 10 ° of < α <170 °, α is larger, and reflective cambered surface 41 regions are larger, can converge light more, be 145 ° specific to α in the present embodiment.
What deserves to be explained is, under the prerequisite ensureing the outgoing of reflection ray collimation, the direct projection light of LED light source 3 is the main causes producing dazzle, therefore wants the cutoff angle of conservative control direct projection light.Composition graphs 4, in the present embodiment, top camber line 412 is bright dipping edge, make any point on top camber line 412 to the line segment of O point with horizontal plane angle β within the scope of 50 ~ 60 °, cutoff angle change greatly, effectively can control the generation of dazzle, guarantee light-out effect.
