Abstract

The invention is applicable to the illumination field, which provides a reflector and a LED lamp. The reflector comprises a truncated cone part arranged at the outer surface of a lamp shell and a reflection part arranged on the side wall of the truncated cone part slantwise. The reflection part is arranged close to the maximum caliber end of the truncated cone part. The side wall of the truncated cone part is provided with a plurality of windows for light source to be exposed. The surface of the reflection part, which faces the minimum caliber end of the truncated cone part, is a reflection face. The plane of the center of the light source is located on an edge at which the reflection face is closet to the minimum caliber end of the truncated cone part. The reflector is arranged in the lamp. Partial upward light beam emitted by the light source of the side wall of the reflector is reflected through the reflection part of the reflector and is projected slantwise and downwards to under the lamp. The illuminance under the lamp is improved and lateral illuminance is not influenced. The invention accords with the requirement of all-round light distribution and the cost is reduced.
