[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figures 1 to 5 As shown, in this embodiment, a double-cover structure bulb includes a glass outer cover 1, a glass inner cover 2, a power supply 3, an inner cover stem 4 and an outer cover stem 5. The inner cover stem 4 is fixed to the outside of the outer cover stem 5, and the glass inner cover 2 is located inside the glass outer cover 1. The lower end of the inner cover stem 4 is arc-shaped and fixedly connected to the lower end of the glass inner cover 2. The lower end of the outer cover stem 5 is arc-shaped and fixedly connected to the lower end of the glass outer cover 1. The upper end of the outer cover stem 5 is fixed with an LED module 6. The LED module 6 is electrically connected to a wire 9. The wire 9 passes through the outer cover stem 5 and is connected to the power supply 3.

[0021] In a more specific structure, a sealed state is formed between the glass inner cover 2 and the inner cover stem 4, an exhaust hole 10 is left on the side of the inner cover glass 2, an exhaust pipe 7 is formed inside the outer cover stem 5, the upper end of the exhaust pipe 7 is connected to the interior of the glass inner cover 2, and the lower end of the exhaust pipe 7 is in a sealed state.
