Abstract

A full spectrum LED grow light with a lens structure includes a shell. The shell is connected to an electric wire and configured with a full spectrum LED unit. The full spectrum LED unit includes LED cells and lenses covering the LED cells. Each of the LED cells can emit full spectrum light. The LED cells are fixed on an aluminum substrate which is electrically connected to the electric wire and fixed inside the shell. The lenses are fixed on the surface of the shell and each lens is configured with at least one LED cell. By combining the LED cells with the lenses, where a single LED cell can emit full spectrum light, the penetrability of light is increased. Thus, not only the upper layer of plant can grow well, but also the middle and lower layers of plant covered by the leaves of the upper layer can grow well.

Claims

1. A full spectrum LED plant illumination lamp with a lens structure, comprising:

a shell, wherein the shell is connected to an electric wire and provided with a full spectrum LED unit;

the full spectrum LED unit comprises LED cells and lenses covering the LED cells, and each of the LED cells emits full spectrum light;
