Description

Energy-saving Water-Cooled Plant Growth LED The present invention relates to an energy-saving water-cooled plant growth LED. Recently, plant growth LEDs that use LEDs as a light source for growing plants indoors have been developed and are being used. Conventional plant growth LEDs have an air-cooling structure that cools the LED using outside air drawn in by a fan to prevent the LED from overheating. Conventional plant growth LEDs with such an air-cooling structure have the problem of low energy efficiency because a large amount of energy is required to cool the LED. FIG. 1 is a combined perspective view of an energy-saving water-cooled plant growth LED according to a preferred embodiment of the present invention. Figure 2 is an exploded perspective view of the energy-saving water-cooled plant growth LED shown in Figure 1. Figure 3 is a cross-sectional view taken along the longitudinal direction of the energy-saving water-cooled plant growth LED shown in Figure 1.
