Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model provides a double-glass-shell light source, which comprises a main body 1, a base 2, an inner-layer glass shell 3, an outer-layer glass shell 4, a light blocking cover 5, a positive conductive nail 6, a positive wire 71, a negative wire 72 and a circuit board 9 with a LED 8.

The main body 1 is a hollow rotary body structure, one end of which is open, and the other end of which is provided with a through hole 11 for the outer layer glass shell 4 to pass through. The base 2 is fixed at one end of the opening of the main body 1, and the positive conductive nail 6 is fixed on the base 2 and extends into the main body 1. The main body 1 and the base 2 are a conductor and an insulator, respectively.

The wiring board 9 is fixed in the main body 1 with the LED8 on the wiring board 9 facing the through hole 11 of the main body 1. One end of the positive electrode lead 71 is fixed on the circuit board 9 and the other end is connected to the positive electrode conductive nail 6, and one end of the negative electrode lead 72 is fixed on the circuit board 9 and the other end is connected to the inner wall of the main body 1. After the double-glass-shell light source is arranged in a shell of the handheld lighting device, the anode and the cathode of a battery of the device supply power to a circuit board 9 through the main body 1 and the anode conductive nails 6 respectively.
