Large-sized LED power generation assembly

Abstract

The invention discloses an LED illuminating device capable of recycling heat. The LED illuminating device comprises an LED light source, a radiating device and a thermoelectric conversion device, the radiating device comprises a semi-closed mould type inner substrate, a built-in semi-closed serpentiform flow guiding tube and an external air blower (or a fan), and the substrate of a radiator is fixed on the back surface of a luminous body of an LED light source plate; when LEDs begin to work, the fan also begins to work, generated heat passes through a serpentiform radiating tube via the air blower, cold air is delivered to the LED radiating substrate, and the heat is delivered to the thermoelectric conversion device. The air blower is shown in a figure 3, an air hose is shown in a figure 4, the radiating substrate is shown in a figure 5, under continuous actions of the air blower, the heat is delivered to a heat strength cavity of a Stirling engine from another port ,as shown in a figure 16, of the radiating substrate via a pipe as shown in a figure 2, the Stirling engine is driven to work as shown in a figure 1, a figure 6 and a figure 7, and power of the Stirling engine is transmitted to a generator, as shown in a figure 8, a figure 9 and a figure 10, to work and generate power.

Description

technical field [0001] The invention relates to a device capable of generating electricity by using the heat of an LED lighting lamp. Background technique [0002] Compared with other lighting sources, LED light-emitting diode lighting sources have the advantages of high luminous intensity, power saving and energy saving. They have developed rapidly in recent years, and the industrial scale has continued to expand. However, with the market's demand for high-power lighting devices, the problem of LED heat dissipation has become a bottleneck restricting the development of the industry. [0003] At present, LED lights on the market mainly rely on natural heat dissipation. From the perspective of heat transfer, natural heat dissipation uses natural convection and thermal radiation as the basic heat dissipation principles. In natural heat dissipation, the basic idea is to use the outer wall of the lamp, especially the fins to convect the surrounding air and radiate heat to the s...
