———1. The energy-saving lamp comes with an electronic ballast, which is the circuit board, after starting, the filament at the two poles in the lamp emits electrons to quickly hit the argon atom to produce an inelastic collision, and the argon atom obtains energy after the collision and hits the mercury atom, and the mercury atom jumps to produce ionization after absorbing energy, emitting ultraviolet rays, and ultraviolet rays excite rare earth trichromatic phosphors to shine. No need for ballast jumping.
- Its start-up characteristics are: the light will be turned on in seconds after power-on, and within 20 minutes, the brightness will gradually increase. It can work in the voltage range of 150V and 300V, but the brightness is somewhat different. Out of range, the lights may turn off and won't light up.
—2. The previous fluorescent lamp was an inductive ballast, which was started by electromagnetic induction, and the ballast bubble jump would be automatically adjusted when the voltage was insufficient.
- Its start-up characteristics are: when the voltage is normal, it can start to shine quickly, it can work normally, and the brightness is also weak and strong. However, if the voltage is not enough, it is difficult to start, and there seems to be gas flowing in the lamp, and the strobe is too large, causing damage to people's eyesight.
—The main difference between the two is electronic ballast and inductive ballast, and the current energy-saving lamp of the lamp has gradually improved into a trichromatic rare earth phosphor with better performance, and the performance is better than that of the previous halogen powder.

Energy-saving lamps are mainly heated by the ballast to the lamp filament, at about 1160K temperature, the filament begins to emit electrons (because the filament is coated with some electronic powder), the electrons collide with argon atoms to produce inelastic collisions, argon atoms collide to obtain energy and hit mercury atoms, mercury atoms jump after absorbing energy to produce ionization, emitting ultraviolet rays, ultraviolet light excitation phosphors.
The energy-saving lamp is mainly through the energy-saving lamp and the embodiment of the low power consumption of the electronic ballast, the electronic ballast not only to ensure that the energy-saving lamp provides the starting current and the starting high voltage under its characteristics, but also to improve the high-frequency and stable AC current of the lamp during normal operation.
You can take apart the energy-saving lamp to see, it has a more complex circuit board, there is also a coil on it, this whole is the electronic ballast, through the switching effect of some electronic components to replace the conventional ballast.

It's just that some people like to call fluorescent lamps energy-saving lamps, and they all refer to the same type of lamps.
The old-fashioned and most of the current curved fluorescent lamps emit light on the same principle, but the starting circuit is different, which used to be completed by a large inductor and starting tube, but now it has been updated, and most of them use electronic ballasts.
You can't draw a picture here, you can't express it.

1.Spotlights should be decorative lighting, such as in wine cabinets or TV walls, it is generally used to illuminate objects (decorative objects), and the power is very small, and it will not hurt **.
2.Energy-saving lamps, also known as self-ballasted fluorescent lamps, and the so-called fluorescent lamps (should be called fluorescent lamps) belong to a similar spectrum, similar to daylight, and belong to functional lighting (different from decorative lighting), which is not harmful to **.
3.When looking at an LCD monitor for a long time, what you need to do is not sun protection, but an intermittent rest of about 1 hour to prevent long-term eye fatigue. (There are also a few people** who are allergic to the radiation of the LCD and also need intermittent breaks).

The fluorescent lamp is also called a fluorescent lamp, there is a filament at each end, the lamp is filled with a trace amount of argon and thin mercury vapor, the inner wall of the lamp is coated with phosphor, and the gas between the two filaments emits ultraviolet rays when conductive, so that the phosphor emits soft visible light. The fluorescent tube relies on the mercury atoms of the lamp, and the ultraviolet light (the main wavelength is 2537 angstroms = 2537 10-10m) is released by the process of gas discharge, and about 60% of the electrical energy consumed can be converted into ultraviolet light, and the rest of the energy is converted into heat energy.
Energy-saving lamps, also known as compact fluorescent lamps (CFL lamps referred to as CFL lamps abroad), have the advantages of high light efficiency (5 times that of ordinary bulbs), obvious energy-saving effects, long life (8 times that of ordinary bulbs), small size, and easy to use. It works on basically the same principle as a fluorescent lamp. Compared with fluorescent lamps, energy-saving lamps now have warm light in addition to white and cold light.

Fluorescent lamp, in the initial stage of igniting the lamp delay tube, needs a high-voltage pulse of more than 400V, once the lamp is ignited, the voltage to maintain normal operation is only about 60 90V, and the power supply is AC220V, so it is necessary to use the ballast and the starter to provide high-voltage pulse when the lamp is lit, and the ballast shares a part of the voltage during the normal work of the buried baggage.
The starter is mainly composed of bimetal sheets, the gap between the contact points is small, and when the electro-hydraulic land connection is connected, the supply voltage is enough to cause a glow discharge through the filling gas. Due to the different thermal expansion of the two metals, the slowly heated contact pieces produce relative bending, and after a second or two, when the contact pieces touch each other, a series circuit is formed through the ballast and the filament, so that a fairly strong current (preheating current) heats the filament rapidly. After the metal sheet is contacted, the glow discharge is extinguished, the metal sheet begins to cool, the contact point pops open, and the series circuit is interrupted, because it is a high inductance circuit, so within 1ms, a high-voltage pulse is generated between the two filaments of the lamp, and the lamp is ignited.

If it's an old-fashioned fluorescent lamp.
Provide a cracked source transient on-off current, so that the rectifier generates instantaneous high voltage, breaking through the source of the lamp high source gas emitting.

It can play a role as a switch.
Professional photographic lights and ordinary energy-saving lamps can not be compared, professional photographic lights are much better than ordinary energy-saving lamps in terms of strobe, color rendering, etc. >>>More
1. After the energy-saving lamp is turned off, it flashes because the switch controls the neutral line, and the live line should be controlled correctly. The switch is connected to the fluorescent lamp through the neutral wire, and when the light is turned off, the filament of the firing wire will discharge the phosphor, and the lamp will be on. Because the circuit is not connected, the electrons on the phosphor have no time to be released, and the live wire does not reach a certain voltage difference between the phosphor, and the lamp is dimmed. >>>More

If the living room is 60 square meters, you can use 80 wattsLED lights;If it is 30 square meters, choose a 40-watt lamp; The living room is 15 square meters, so it is enough to choose 18 watts. If the living room is large, you should choose a lamp with a larger wattage, and the electricity consumed will be relatively large. >>>More
