Abstract
The utility model discloses a reflector of an LED road lamp, which is mounted at the periphery of an LED lamp. The reflector is characterized in that the reflector comprises a frame-type reflective cup; and the middle part of a side wall of the frame-type reflective cup extends inwards and forms an outward arc-shaped reflective surface with other two sides. The shape of an LED reflective cup is modified and designed optimally, so that the long bat wing type radiation form required by a road lamp is achieved, the range is far, the range of the effective light spots is large, the light-emitting efficiency of an LED luminaire is improved, the high-efficiency and energy-saving purposes of the LED luminaire are achieved.
Description
Technical field
The utility model relates to technical field of lamps, particularly a kind of reflective structure of LED road lamp.
Background technology
Present LED road lamp, Tunnel Lamp in use because the led light source range is short, effective hot spot scope is less when using the lens luminous intensity distribution, the lamp installation limitation in height is below 8M.The led light source forms of radiation is mainly circle or lambert's type, do not reach the required bat aerofoil profile forms of radiation of road lighting, using the reflector luminous intensity distribution, because the constraint of design optimization ability, do not reach desirable effective hot spot scope when causing the LED light fixture to use, thereby cause LED light fixture light extraction efficiency to descend.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of not only simple in structure, weight is little, cost is low, and the effective big LED road lamp reflector of hot spot scope.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of LED road lamp reflector, be installed in LED lamp periphery, it is characterized in that: it comprises a frame type reflector, the middle part of the sidewall of this frame type reflector extends internally, and constitutes the outside arc reflective surface of direction with its dual-side.
As further specifying of such scheme, the two side of described frame type reflector is symmetrically distributed, and the lateral cross section of the one-sided sidewall of this frame type reflector is " people " font.
The bottom opening of described frame type reflector, the middle part of the sidewall of reflector extends inward as rib, and the end of two arc reflective surfaces is connected on this rib.
The angle of two arc reflective surfaces of described connection rib is 45～80 °.
The central angle of described arc reflective surface correspondence is 15～90 °.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model is optimized improvement design to LED reflector shape, reaches the required long bat aerofoil profile forms of radiation of street lamp, makes setting height(from bottom) than existing product about 2m of lifting be arranged, far firing range, effectively the hot spot scope is big, allows LED light fixture light extraction efficiency promote, and reaches the energy-efficient purpose of LED light fixture.

The specific embodiment
As Fig. 1～shown in Figure 4, a kind of LED road lamp of the utility model reflector is installed in LED lamp periphery, and it comprises a frame type reflector 1, and the middle part of the sidewall of this frame type reflector 1 extends internally, and constitutes the outside arc reflective surface 2 of direction with its dual-side.The two side of frame type reflector 1 is symmetrically distributed, the lateral cross section of the one-sided sidewall of this frame type reflector 1 is " people " font, the bottom opening 3 of reflector, the middle part of the sidewall of reflector extends inward as rib 4, the middle part of rib 4 is recessed, the end of two arc reflective surfaces 2 is connected on this rib 4, and the angle a of this arc reflective surface 2 is 45～80 °, and the central angle of arc reflective surface 2 correspondences is 15～90 °.
The utility model is not limited to the foregoing description, and those skilled in the art also can do numerous modifications and variations, under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
Claims (5)
