Energy-saving lamp classification

Energy-saving lamps can be divided into two categories: single-end fluorescent lamps (PL energy-saving tube lamps) and self-ballasted fluorescent lamps (electronic energy-saving lamps).

A single-end fluorescent lamp refers to a single-lamp low-pressure mercury vapor discharge lamp. Most of the light emitted by the discharge is activated by a UV-activated phosphor coating. Can be removed from the lamp, used in specially designed lamps, with the control circuit integrated with the lamp, to achieve the purpose of decorative or optimized lighting design. The lamp cap has two pins (2P) and four pins (4P). The two-pin cap contains a starter (also known as a jump bubble) and an anti-interference capacitor, while the four-needle cap has no circuit components.

Single-end fluorescent self-ballasted fluorescent lamps come with a full set of control circuits for ballasts and starter lamps, and are equipped with screw-type lamp holders or socket-type lamp holders. The circuit is generally enclosed in a housing and the control circuit in the lamp assembly is dominated by high frequency electronic ballasts. This integrated compact energy-saving lamp can be directly mounted on the base of a standard white-knit lamp, and the white-knit lamp can be replaced directly, which is more convenient to use.
