Energy-saving lamps, also known as power-saving bulbs, electronic bulbs, compact fluorescent lamps, and integrated fluorescent lamps, are lighting devices that combine fluorescent lamps with ballasts (ballasts).
Parameter indicators of high quality energy-saving lamps
Electrical parameter
(1) Voltage range: rated voltage +10%-20% energy saving lamp
(2) Power range: rated (nominal) power +5%-10%
(3) Power factor: According to the actual situation, choose PF>0.6 and PF>0.9
(4) Compliance with safety regulations and electromagnetic interference and electromagnetic compatibility EMC requirements
(5) The operating frequency of the electronic ballast avoids the remote control frequency of the household appliance
(6) Comply with stable and reliable working requirements in high temperature environment and low temperature environment
2. Light parameters
(1) Luminous flux: the sum of the amount of light emitted by the light source per second: used to indicate the amount of light emitted by the tube, that is, the amount of luminescence. The general symbol Ñ„ indicates that the unit is lumens (Lm).
Light efficiency, luminous flux requirements: less than 15W, light efficiency requirements ≥ 45LM / W; greater than or equal to 15W, light efficiency requirements ≥ 60LM / W.
(2) Color rendering index: ≥ 80
(3) Color temperature: small color temperature deviation and good consistency
(4) Start-up time: less than or equal to 1 second
3. Life parameters
(1) The effective life is more than 8,000 hours (the lumen maintenance rate is over 70%)
(2) It can work stably and reliably under the effective life period, high temperature 85 °C environment and low temperature -20 °C environment; and under the above temperature conditions, the energy-saving lamp can work stably and reliably under the impact of voltage fluctuation.
4. Mechanical parameters
(1) The connection strength between the lamp and the electronic ballast meets the specified torque requirements.
(2) The lamp cap is connected to the housing to meet the specified torque requirements.
Classification of energy-saving lamps
Energy-saving lamps can be divided into two categories: self-ballasted fluorescent lamps (electronic energy-saving lamps) and single-ended fluorescent lamps (PL plug-in energy-saving tube lamps).
The self-ballasted fluorescent lamp has a complete control circuit for the ballast and the starter lamp, and is equipped with a spiral lamp cap or a socket lamp cap. The circuit is typically enclosed in a housing, and the control circuitry in the lamp assembly is dominated by high frequency electronic ballasts. The integrated compact energy-saving lamp can be directly mounted on the lamp holder of a standard white-woven lamp, and the white-woven lamp can be directly replaced, which is convenient to use.
Single-ended fluorescent lamps refer to single-lamp low-pressure mercury vapor discharge lamps, most of which are emitted by the ultraviolet-activated phosphor coating produced by the discharge. It can be removed from the luminaire, used in specially designed luminaires, and designed to optimize or illuminate the lighting function by means of a control circuit integrated with the luminaire. The lamp holder has two needles (2P) and four needles (4P). The two-pin lamp holder contains a starter (also called a bubble jumper) and an anti-interference capacitor, while the four-pin lamp holder does not have any circuit components.
