2.3 Electric Lamp Subcategory
2.3.1 Description Production Process
Incandescent, fluorescent, electric discharge lamps (besides conventional fluorescent) and tungsten filaments used in the production of electric lamps are major
electrical and electronic components that are manufactured under this subcategory.
As lamps, they are used for illuminator, lighting, photoelectric, and photochemical
effect purposes. Some of them are important components of electric circuits for
demonstrative, household, and industrial uses. The production of components of this
subcategory is meant for commercial purpose and acceptability, optimized light
generation, illumination efficiency, as well as lamplife. Table 4.16 summarizes the
types of artificial light production and related products. The flow chart of lamp
phosphor process is presented in Fig. 4.1.
