## Abstract

The present invention relates to the technical field of LED street lamp, in particular to structure of a reflector panel of the LED lamp. A reflector panel comprises a base, the base has multiple reflector cups, which are divided into two groups according to the direction of their openings, all reflector cups in each group have the same direction of their openings, the directions of the openings of the reflector cups in two different groups are opposite. The reflector panel of the present invention can form the illumination band with even illuminance on the street and cause small light loss.

## Claims

### Claim 1

A reflector panel of a LED street lamp comprising a base plate, the said base plate has multiple reflector cups, characterized in that the said reflector cups are divided into two groups according to the direction of their openings, one of which with the direction of all cup openings the same and the other of which with the direction opposite to the street direction.

### Claim 2 (depends on 1)

The reflector of a LED street lamp as claimed in claim 1, characterized in that the reflector cup comprises the top, bottom, and the reflector part that connects the top and bottom, the said reflector part consists of an inner transverse face, an outer transverse face, an inner vertical face and an outer vertical face; the said inner transverse face and outer vertical face are planes, the said inner vertical face and inner transverse face are curved planes.

### Claim 3 (depends on 2)

The reflector of a LED street lamp as claimed in claim 2, characterized in that the inner vertical face is a cylindrical surface, the said inner transverse face is a paraboloid.

### Claim 4 (depends on 1)

The reflector of a LED street lamp as claimed in claim 1, characterized in that the base plate has multiple base holes, which are used for supporting the reflector cups. The bottom of each reflector cup has a stop frame for stopping the reflector cup from exceeding the required position.

### Claim 5 (depends on 4)

The reflector of a LED street lamp as claimed in claim 4, characterized in that: the back of the said reflector cup has a buckle, the back of the said base plate has a slot matching the buckle, the said buckle has a reinforcing rib; there are multiple convex ribs along the radial direction of the edge of the base hole; the back of the outer transverse face of the said reflector cup has a buckling strip.

### Claim 6 (depends on 2)

The reflector of a LED street lamp as claimed in claim 2, characterized in that the included angel between the outer transverse face and the base plate is within 25˜45°, between the inner transverse face and the base plate is within 70˜90°, the included angel between the said outer vertical face and the base plate is within 50˜70°, between the inner vertical face and the base plate is within 95˜110°.
