Energy-saving lighting, ventilating and rain-proof louver

The invention discloses an energy-saving lighting, ventilating and rain-proof louver. The technical problems to be solved are as follows: conventional louvers basically have ventilation and decorationfunctions, and play a certain role in shielding, but more importantly, the conventional louvers play a role of being rainproof; general louvers can only add louver blades to prevent rain, but ventilation requirements cannot be met; and in addition, the inner sides of ventilating and rain-proof louvers are lightproof, so that indoor lights need to be turned on all year round. To solve the technical problems, the adopted technical schemes are as follows: The louver adopts a louver with double layers; the external louver is inlaid with a novel transparent material; the internal louver has louverblades which can automatically open and close; the external louver and the internal louver are in inverted-V-shaped arrangement; the external louver can realize the first waterproof and lighting function; and the internal lou
