Compared with the prior art, the utility model discloses beneficial effect as follows:

(1) the metal coating reflecting film is sprayed on the surface of the bulb, and a mirror surface is formed on the outer wall of the glass bulb, so that the reflecting effect is achieved;

(2) the light leakage at the neck of the bulb is greatly reduced, the reflecting film of the outer plating metal coating can be plated to be 0-10mm away from a standard lamp cap, if the lamp cap with the insulating ring is used, the width of the insulating tape is 0, the distance between the metal coating and the lamp cap is zero, and the effect of complete light leakage is achieved;

(3) the lamp cap, the insulating tape and the light-transmitting area of the bulb are shielded during film coating, the metal coating and the conductive part of the lamp cap need to keep a certain distance, namely the insulating tape, so that the lamp cap is prevented from being conductive to the metal coating reflection film, and the metal coating reflection film is safer although the outer layer of the metal coating reflection film is not conductive;

(4) the reflecting film with the plated metal coating does not have an acid washing or alkali washing process, so that the wastewater discharge is reduced, the cost of wastewater treatment of enterprises is saved, and the environment is protected; because the acid washing and alkali washing processes are not carried out, acid and alkali can not remain in the bulb, and the service life of the bulb is prolonged;

(5) the metal coating is positioned on the outer surface of the bulb glass shell and is directly contacted with air, so that the heat dissipation effect of the bulb is better, basic conditions for heat dissipation are provided for manufacturing and using high-power bulbs, and experiments prove that bulbs with the same volume size and the power exceeding 2000W of the existing bulbs can be manufactured;

(6) the outer surface can be sprayed with metals with various colors such as gold, silver, red and the like, and different gases can be added in the ion plating process, so that the metal ions can present different colors, and the lamp bulb is more special and beautiful.
