Abstract

A lighting device with high energy conversion efficiency comprises a light source substrate and a heat energy recovery system. The light source substrate comprises a substrate and a plurality of light-emitting units, and the light-emitting units are arranged on the substrate. The heat energy recovery system comprises a temperature difference effect power generation chip, a first radiator and an energy storage circuit. The heat absorption surface of the thermoelectric effect power generation chip is connected with the substrate, the heat dissipation surface of the thermoelectric effect power generation chip is in contact with one side of the first radiator, and the energy storage circuit is connected with the thermoelectric effect power generation chip to store energy generated by the thermoelectric effect power generation chip so as to supply power to the light emitting units.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lighting device with high energy conversion efficiency. The invention also relates to a thermal energy recovery method of the lighting device. Background technique [0002] Every industry is working towards improving efficiency and being more environmentally friendly. Among them, the application of lighting products is popular and the power consumption of lighting devices accounts for about 30% of the total power. Therefore, if the efficiency of the lighting device can be higher, it will be more helpful to achieve the aforementioned goals. [0003] Although the existing light-emitting diode lighting devices have been able to achieve higher efficiency than traditional lighting devices. However, the electrical conversion efficiency of light-emitting diodes in lighting devices is generally not high, and the electrical conversion efficiency of even the most advanced light-emitting diodes doe...
