Abstract
The invention provides an LED lighting device. An S-shaped liquid cooling pipe is arranged on the back of a substrate. A hexagon-shaped LED lamp is correspondingly arranged on the front of the substrate. By means of heat conduction of a middle substrate and the S-shaped liquid cooling pipe, heat generated when the LED lamp emits light is transmitted to a thermoelectric converter in time to be converted into electric energy. Meanwhile, when the LED lamp emits light, partial light rays which are emitted to the two sides and the rear correspondingly illuminate on a photoelectric converter on the inner side of a photoelectric protection sleeve so that the lost part of light energy is converted into electric energy which is converged to a circuit board together with the electric energy generated through thermal conversion. Afterwards, electric energy can drive the LED lamp to emit light is generated after circuit processing by the circuit board. According to the LED lighting device, lost light energy and heat energy when the LED emits light are converted into electric energy which can be used again. Thus, the luminous efficacy of the LED and the radiating effect of light emitting of the LED are radically improved, consumption of light in the lighting process of the LED is reduced and waste of emitted light is reduced.
