一般に行なわれている。High-efficiency discharge lamps with relatively high color rendering properties, such as high-pressure sodium lamps and metal halide lamps, are used for high-ceiling lighting in gymnasiums and indoor and outdoor lighting such as airport lighting. These discharge lamps have a light-transmissive envelope made of gas, etc., and have a light-emitting tube equipped with electrodes at both ends and containing a light-emitting material such as sodium iodide or indium iodide. In order to improve the luminescent color of a discharge lamp, the luminescent material is formed into a small-diameter pellet and then introduced into the arc tube through the exhaust pipe of one arc tube.

Because it can be done mechanically, there is no need to do it manually, and automation is easy.1 The hopper, luminous tube, and pellet dropper shown in the figure can be placed in a vacuum such as a Pel jar or in a timed atmosphere such as an inert gas. Because the pellets can be held and operated, it is easy to prevent chemical reactions such as oxidation of the pellets, and even if the pellets are small and fragile, a predetermined amount of pellets can be placed inside the arc tube without applying force that would crush the pellets. It is possible to have pressure built in.
