Abstract

The invention discloses a large-angle luminous LED (Light Emitting Diode) lamp, which comprises a lamp cap, a radiator, an LED light source and a lampshade. The radiator is arranged on the lamp cap. The bottom of the lampshade is connected with the outer edge of the top surface of the radiator. The large-angle luminous LED lamp additionally comprises a supporting rack and a transparent substrate. The supporting rack is arranged in the center of the top surface of the radiator. The transparent substrate is arranged on the end surface of the supporting rack. The LED light source is arranged at the top of the transparent substrate. A first fluorescent powder layer is coated at the bottom of the transparent substrate at a position which faces right to the LED light source. The large-angle luminous LED lamp provided by the invention has the advantages that since the transparent substrate is used, the single-sided LED light source which is arranged on the transparent substrate realizes the bidirectional light emitting effect and the quantity of the used LED light sources is reduced; and since a light reflecting layer on the top surface of the radiator outwards reflects light which is emitted to the radiator to enable the light to be emitted to the lampshade, the luminous efficiency is improved.
