Abstract

The invention relates to an LED lamp with high lighting efficiency. The LED lamp comprises a lamp body; a lamp holder is arranged at the tail end of the lamp body; a light source die set is arranged at the front end of the lamp body; at least two lenses which are matched with each other are also arranged at the front end of the lamp body, positioned in front of the light source die set and close to each other; the at least two lenses which are matched with each other include a first lens which is closed to the light source die set, and a second lens which is far away from the light source die set. The LED lamp with the high lighting efficiency is simple in structure and small in material cost; in addition, the characteristics of small requirements on assembling precision and convenient assembling are brought; the lens set is positioned in front of the light source die set, and thus the light waste and light pollution of the lamp can be effectively reduced.

Description

technical field [0001] The invention relates to semiconductor lighting technology, in particular to an LED lamp with improved luminous efficiency. Background technique [0002] Because of the advantages of energy saving and long service life, semiconductor lighting is becoming more and more popular, and it has a tendency to gradually replace traditional lighting technology. Existing LED bulb lamps basically have a lamp body, a light cover is installed at the front end of the lamp body, a screw hole is installed at the rear end of the lamp body, a driving part is installed in the lamp body, and cooling fins are arranged around the lamp body. [0003] For example, Chinese patent document CN201401651 discloses a novel LED lamp on February 10, 2010, which relates to a lamp. It is composed of a lamp housing, a reflector lampshade and LED lamps. The LED lamps are arranged on both sides of the lamp housing, and the reflector lampshade is arranged on the upper end of the lamp housi...
