Abstract
A structure for a high diffuse efficiency and water-proof lighting device is provided, including a light tube and a base holder. The light tube and the base holder are each an enclosed structure. The light tube includes a circuit substrate inside the enclosed structure. The circuit substrate includes a plurality of LEDs. The light tube and the base holder each include two holes close to both ends. When the light tube and the base holder are assembled, the holes match so that the wire connecting the circuit substrate can go through the holes to enter the base holder. A water-proof and highly pull-resistant glue is used to fill the overlapping of the holes. A resilient element is used to connect the neighboring circuit substrates, the resilient element can absorb the deformation caused by the temperature changes so that the light diffusion remains uniform. Therefore, the lighting device can perform well even when operating in an environment with drastic temperature changes.
