The lantern lamp disclosed in the new type is comprised of a housing, a light source assembly, and a driving component. The light source assembly consists of two LED light boards placed opposite to each other. The first LED light board has a first heat dissipation aluminum substrate with several LED chips arranged on it, while the second LED light board has a second heat dissipation aluminum substrate with LED chips arranged on it as well. The aluminum substrates are designed with alternating heat dissipation holes. The driving component is connected to a power cord that extends out of the housing, and the junction between the housing and the power cord is securely sealed with glue. The overall shape of the lantern lamp is similar to a long tube, and it can be easily installed in a lantern as a replacement for traditional tungsten bulbs. The lamp offers energy-saving benefits, a longer operational lifespan, and an appealing aesthetic. Additionally, the design incorporates an intermediate seal that effectively guards against dust and water, thus ensuring durability and protection.
