DEVICE FOR APPLYING A MIRROR COATING ON A PART OF THE INTERNAL SURFACE OF BULBS OF ELECTRIC LIGHTBULBS

摘要

The invention relates to electrical engineering and can be used for applying a mirror coating on a part of the internal surface of bulbs of electric lightbulbs during the production of light sources. Said invention extends the scope and improves the operational reliability of the device, increases the performance of a process for applying the mirror coating on the bulbs and prevents the bulbs from being destroyed. The inventive device for applying a mirror coating on a part of the internal surface of bulbs of electric lightbulbs comprises a scavenge unit with a seal ring, electrodes with an evaporator which are secured in said unit and the central and lateral parts of a screen with elements for pivoting said parts. The scavenge unit consists of a cap and a base, between which the seal ring is located, the bulb is totally arranged inside the scavenge unit and is mounted on the central part of the screen, and the elements for pivoting the lateral screens are moved outside of the bulb and are positioned inside the scavenge unit.
