Abstract

The present invention relates to a light emitting diode (LED) lamp in which a compound lens is formed on a base and a device for lowering the heat of light emission is arranged to operate a fan using an oscillator when a temperature rises during light emission such that light emitted from a light emitting diode may not scatter but rather diffuses and linearly advances, thus maintaining a low temperature during light emission and maximizing light emitting efficiency and heat dissipating efficiency. For this purpose, the light emitting diode lamp of the present invention comprises: a base (10) in which a plurality of heat dissipating tubes (11) having different lengths is arranged to introduce and discharge external air so as to realize a convection current, and on which a plurality of light emitting diodes (13) is connected and grounded via a circuit board (12); a compound lens (20) having first, second, and third lenses (21, 22, 23) arranged on a center of the base (10) to enable light emitted from the light emitting diodes (13) to diffuse and linearly advance rather than scatter, thereby maximizing light emitting efficiency; a cap (30) coupled to an outer surface of the base (10) to support the compound lens (20) such that the compound lens (20) may not escape from the base (10); and a device for lowering the heat of light emission (50) which is arranged at a lower surface of the base (10) and which lowers the temperature of heat during light emission so that the temperature is sensed by a temperature sensor (40) during light emission by the light emitting diode (13) and a signal is transmitted to an oscillator (51) from the circuit board (12) so as to operate a fan (54) to forcibly dissipate high temperature heat to the outside via the heat dissipating tubes (11).
