What kinds of energy-saving lamps are there?
1. Living room energy-saving lamps are divided into self-ballasted fluorescent lamps (electronic device energy-saving lamps) and single-ended fluorescent lamps (PL plug-in environmental protection and energy-saving lamps).
2. Self-ballasted fluorescent lamp has built-in electronic ballast and drive lamp control loop, and is equipped with screw lamp holder or jack lamp holder. The power supply circuit is generally encapsulated in the shell, and the control loop of the lamp part is dominated by the high-frequency electronic ballast. This integrated compact energy-saving lamp can be directly installed on the socket of standardized fluorescent lamp, and the fluorescent lamp can be replaced immediately, which is convenient for application.
3. Single-ended fluorescent lamp refers to a low-pressure mercury vapor discharge lamp with a single base, and most of them only rely on ultraviolet light generated by charging and discharging to excite the phosphor coating to emit light. In the lighting fixture that can be detached from the lighting fixture for professional customization, the decorative design or functional design of the lighting fixture can be realized by generating an integrated control loop with the lighting fixture. There are two kinds of lamp holders: two pins (2P) and four pins (4P). Two-pin lamp holder contains upconverter (also called bubble jumping) and anti-interference capacitor, and four-pin lamp holder has no power circuit electronic devices.
How to choose energy-saving lamps
1, many users think that the energy-saving lamp is a small object, so don't care too much, but if the choice is unreasonable, the service life and light of the energy-saving lamp will be wrong. In fact, energy-saving lamps have commodity brands. I would like to share with you a way to choose energy-saving lamps or other new products: refer to the list of qualified suppliers of government procurement projects in China, choose registered well-known brands, and if it is energy-saving lamps, you can also test two certification marks: "CQC (Safety Certification)" and "Jie (Energy Conservation Certification)".
2. There is a strong demand for energy-saving lamps, and there are certainly many fake and inferior commodities. If you can't achieve the effect of energy-saving lamps, it will be affected in many aspects, such as safety, physical and mental health. If you choose energy-saving lamps, first look at the outer packaging box of new products, registered trademarks and actual power are all issues that need attention. Secondly, better energy-saving lamps are smooth, and the luminescent powder in the lamp tube is milky white. The lamp holder and light pipe should be vertical and should not be skewed. The contact area between the lamp holder and the power supply should be neat. The information content marked on the lamp should also be clear and easy to distinguish, and the paste should be firm, and the handwriting and pattern design should not be blurred and overlapped.
3. The latter simple way must be assembled and plugged in before watching. Turn on the light for 5 seconds and then turn off the light for 55 seconds. Observe that the tungsten wire turns from black to yellow. Generally, there are no black and white energy-saving lamps. In addition, under normal circumstances, a better energy-saving lamp, after being electrified, lights up a little dark for a while, and then suddenly lights up after a few seconds. Qualified energy-saving lamps can reach more than 5000H under test conditions and more than 2000H under normal start-up life. If they can't reach it, it's a fake and shoddy product.
