The specific embodiment
The utility model discloses a kind of reflector 1, shown in Fig. 1,2,3,4,5, the whole inclined ladder body cup-like structure that adopts, wherein, described reflector 1 includes the above parabolic surface of one side, and the opposite of described parabolic surface is the inclined plane.
Described reflector inner surface is provided with high reflexed light film 4.
The bottom of reflector 1 has the opening of rectangle, and the top has the opening of rectangle, and open-topped length and width dimensions be greater than the length and the width dimensions of bottom opening, and open top and bottom opening are not concentricity.
Definition is positioned on the bottom surface of reflector 1, and is respectively X-axis, Y-axis with the parallel respectively two orthogonal axles of the long limit of the bottom opening rectangle of described reflector 1 and broadside, and described reflector 1 is unsymmetric structure with respect to X-axis, Y-axis.
The two opposite sides wall of the reflector 1 that described X-axis is passed is respectively first parabolic surface and first clinoplain; The other two opposite sides wall of the reflector 1 that described Y-axis is passed is respectively second parabolic surface and second clinoplain.
Described first parabolic surface or second parabolic surface are for from the bottom, and be progressive to the close rounding off curved surface of the luminous normal of led light source; Fillet surface is an irregular surface, does not have specific R value; Be to generate by the multilayer rectangle lamination of vertically arranging at a certain distance, every layer figure is close, and is by little and big, overall oblique to a horizontal left side (right side) inclination.On the other side is first clinoplain or second clinoplain, is able to from opposite direction " escape " thereby force from the light of LED outgoing.
The angle inclination of the light of LED outgoing in X-axis and Y direction, the lighting demand of realization LED street lamp and outdoor lighting light fixture are controlled and realized to described first parabolic surface or second parabolic surface respectively.
The asymmetry of inclined ladder physique structure is that led light source is not or not the center of reflector parabolic surface, but along the center line of reflector bottom, close to the maximum refractive surface of reflector, in the hope of making LED emergent ray " escape " in the opposite direction, this will form the asymmetry luminous intensity distribution of reflector.
The parabolic surface of the inclined ladder physique structure of asymmetry has directionality, according to the lighting environment needs, distributes in led light source line bilateral symmetry.
Adopt a kind of vacuum evaporation process on the described reflector inner surface, be coated with reflectorized material evenly, securely, form high reflexed light film at the optical surface of reflector.
The utility model discloses road lamp device simultaneously, as Fig. 1,2,3, wherein, includes above-mentioned reflector 1 and light source; Described light source is installed in the zone between the inclined plane on the parabolic surface of bottom of reflector 1 and opposite.
Described light source is a kind of led light source 2.
The bottom opening place of described reflector 1 is provided with a lamp plate 3, and led light source 2 is installed on the lamp plate 3.
Along X-direction, described led light source 2 is positioned at the side near first parabolic surface; Along Y direction, the centre position of described led light source 2 between second parabolic surface and second clinoplain.
Reflector 1 in the utility model is one to have the inclined ladder physique structure of the asymmetry of parabolic surface, and it is installed on the LED illuminating source, and wherein the reflector surface is provided with high reflexed light film.When light source luminescent, light to around disperse, then be reflected outgoing in the opposite direction after running into the parabolic surface of even coating reflective membrane; On the other side is a clinoplain, is able to from opposite direction " escape " thereby force through parabolic surface reflection and from the light of the direct outgoing of LED.The light of reflector is escaped and is exported to length-width ratio is 2: 1 above rectangles, and the light that led light source is launched is finally all escaped from this rectangle outlet through the reflexed light film on the parabolic surface face, thereby the formation length-width ratio is 2: 1 above rectangular light spots.Each reflector of horizontally set left and right sides can form 4: 1 rectangular light spot, thereby can satisfy the demand that the street lighting spacing widens day by day.According to the power demand of lighting, led light source can present the geometric array of some, and corresponding reflector also presents how much corresponding arrangements.
As Figure 6 and Figure 7, owing to be positioned at the asymmetry reflector that has parabolic surface of led light source top, its surperficial face is provided with high reflexed light film 4, and the light that sends tilts to penetrate towards a direction through the reflection back is whole, realizes the directive skew of light.After light reflects through MS1-1, towards the MS1-2 direction; After light reflects through MS2-1, towards the outgoing of MS2-2 direction.Light fixture is under the condition at the smaller elevation angle like this, and to the road of needs illumination, and vertically projection distance is far away ray cast, thereby provides light fixture to be used for the utilization rate of road lighting.
By as can be seen above, reflector described in the utility model, the direction of propagation of light is offset, led light source cooperates reflector described in the utility model, can produce length-width ratio and be 2: 1 above gradually like rectangular light spot or ellipse light spot, between the adjacent like this hot spot then shade can not appear, arrangement pitch according to conventional light pole, can on road, form a bright illumination light belt, thereby meet the illumination design of present traffic route, but also improved the illumination utilization rate of light fixture.
More than a kind of reflector provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
