Abstract

The utility model discloses an LED lamp which comprises a radiator, an LED light source module and a power supply module. A heat conducting column is arranged on the radiator. The LED light source module comprises a flexible lamp belt attached to the heat conducting column. The flexible lamp belt can be in volume production in a mono-block mode through automatic equipment or sheared after whole strips are produced. The flexible lamp belt is high in production efficiency and low in cost. At assembling time, the flexible lamp belt is directly and annularly attached to the heat conducting column so as to be high in assembling efficiency and be capable of realizing 360-degree illumination. Further, a compression piece capable of compressing the flexible lamp belt on the heat conducting column is arranged on the heat conducting column so as to prevent glue failure of the flexible lamp belt. Consequently, lighting effect and heat conducting efficiency can not be influenced, and the structure of a lamp is more reasonable and reliable. Further, the groove wall of a through groove is designed to be an oblique surface, and a reflecting layer is arranged on the oblique surface, so that light ray shielding loss, caused by the through groove, of the LED light source is reduced. The reflecting layer can be used as a reflecting cover, so that the irradiating range of the lamp is further expanded, and dead corners of illumination are reduced, or a light gathering role can be played.
