Furthermore, the glass shell is provided with an inward concave structure at a position 2-10mm away from the bottom.

Furthermore, the inner wall of the front panel and the three metal rods of the core column are fixedly connected in a triangular distribution manner.

Compared with the prior art, the invention has the advantages that: the invention relates to a long-life light source-deuterium lamp on a medical detection device, which is provided with a metal shell structure in a bulb filled with deuterium. The general life-span of current domestic deuterium lamp is 500 hours, compares with the general 2000 hours life-span abroad, and the short-lived leading reason has 2, and firstly the gas leakage is lighted, secondly luminous intensity is low, can't satisfy the use of equipment. In order to solve the 2 problems, the invention increases the service life of the deuterium lamp by specially designing the inner and outer structures of the deuterium lamp.

Carrying out optical grinding in the light transmission area to reduce the thickness of the special glass, and simultaneously carrying out optical coating to increase the light transmission effect; the stability of the structure is ensured by a triangular three-point fixing mode; the special appearance and bonding mode of the lamp shell ensure that the lamp shell cannot crack and leak gas in use.
