The English name of an energy-saving lamp is usually called ENERGY SAVING LAMP (ESL for short) or COMPACT FLUORESCENCE LAMP (compact fluorescent lamp, CFL for short), or BULB (bulb).

The products are mainly made up of energy-saving lamp tubes, pcb boards, plastic shells plus lamp holders and packaging, but the PCB board is invisible, and can only be seen when the energy-saving lamp is turned on. The main technical terms of the electronic energy-saving lamp are: model, working voltage, wattage, lamp, color temperature, lumen, lamp, light failure, plastic, lifespan, etc., the following one to explain.
model:
You can generally see 2u series, 3U series and other energy-saving lamps on supermarkets. What does this mean? Everyone knows that the lamp of an energy-saving lamp is U-shaped, 2 lamps are 2U, and 3 lamps are 3U. There are no major differences between other lamp tubes of different shapes. The main difference is the power level. Generally, the larger the wattage, the longer the length, the thicker the lamp and plastic.
Operating voltage voltage in V:
It refers to the voltage required for energy-saving lamps to work. Normally, our countries and most countries in Asia are 220v (except Japan and South Korea), Europe is 230v, Australia is 240v, North America (USA), Japan (South Korea) and most The South American countries are 110v and DC 12V, mainly for use on ships or on solar energy. In addition to the voltage, the power supply also has a frequency requirement. The general frequency is 50Hz or 60Hz. However, the frequency has little to do with energy-saving lamps. Usually, the energy-saving lamps produced by our company can work normally within the range of -20% to +10% of the working voltage, such as 220V, then the ratio is calculated as: 176v-242v normal voltage operation, which avoids some countries because the voltage is not The large number of energy-saving lamps caused by the stability is broken. It is important to state that the more stable the power supply, the longer the service life; the fewer the number of switches, the longer the life expectancy.
Watt power in W:
Power has two concepts of actual power and print power. Print power is usually a concept that everyone can see, and most customers can also accept the concept; but the actual power is invisible, only measured by the instrument, in order to prevent The unscrupulous manufacturers falsified themselves, posing high power at low power, thereby saving money (usually the lower the power, the cheaper the price). China has introduced a national standard for energy-saving lamps, GB/T17263-2002, which stipulates that the actual power must not be less than 85% of the print power. However, due to the different requirements of commodity inspection in different cities in China, the phenomenon of posing high power with low power is still common.
Lamp base:
The lamp head refers to the head of an energy-saving lamp, usually E27/E26/B22/E14. E27 is needed by most of the markets. China basically uses this type of lamp; E26 is the United States and Canada; B22 is the British and British colonial countries, such as: India, Pakistan, Australia, etc.; E14 is a small lamp. Materials are copper, iron, aluminum, etc. The price is also from high to low. The difference is that the iron lamp has a long time to rust and the aluminum lamp head is relatively soft.
Color temperature Color temperature, the unit is K:
It refers to the color of light when the light is on, usually from 2700k to 7000k. The higher the color temperature, the more white it looks. The brighter it is, it is not. Then there are some professional English about color temperature, warm color is 2700k, daylight is 6400k, cool daylight is 6500k-6700k, and so on. The color temperature has nothing to do with the price of the lamp. But with the production, usually 2700k, 6400k, 6500k and 6700k, more commonly used, the number of restrictions is not very strict, other, such as: 4100k and other color temperature, lamp suppliers have a certain number of requirements.
