摘要： An LED element with a color light enhancement function is a two-terminal element for receiving a driving current to emit light and includes at least one blue LED chip, at least one red LED chip and a three-way compensator. The three-way compensator intercepts a driving current passing through the blue LED chip depending on a proportion value according to a change of working temperature and adjusts the amount of current flowing into the red LED chip. If the working temperature exceeds a default value, an input terminal of the three-way compensator is triggered to intercept the driving current and generate and output a set current to the red LED chip to compensate an attenuation of the red LED chip caused by high temperature. The LED element will not be changed its intensity after a prolonged period of usage.
