First, compare with the inductance ballast:
1, high efficiency and energy saving:
The operating frequency of the inductance ballast is 50HZ, the operating frequency of the electronic ballast is 20~50KHZ, and the luminous efficiency of the lamp is higher than that of the power frequency by 10% at the high frequency. Therefore, the electronic ballast has higher brightness than the inductance ballast; The electronic ballast itself consumes less power, such as the same brightness, the use of electronic ballasts than the magnetic ballast energy saving of about 20 to 30%; where the magnetic ballast increases the indoor temperature, the need for air conditioning in summer cooling Electricity bills are not counted. General lighting in hospitals accounts for about 70%. Using high-performance electronic ballasts can save 2 to 3 months of electricity bills compared to high-quality ballasts. The cost of lighting can be gradually recovered, and the cost of running the property can be reduced.
2, comfortable:
Inductance ballast will produce strobe light, work in this environment, learning visual fatigue. It is easy to create illusions for high-speed rotating objects, and there are hidden accidents. At the same time, the inductance ballast emits low-frequency noise of 50Hz, which is irritating. In the ENT listening room, electronic ballasts should be used in fluorescent lighting to prevent misdiagnosis. In the wards and waiting halls, fluorescent ballasts should not be used. The main concern is that the strobe and noise will cause the patient to Discomfort. Electronic ballasts can be used to eliminate stroboscopic flash and protect eyesight. The eye pupils of the market are designed using electronic ballasts equipped with three-color light tubes. High-performance electronic ballast with no flicker, no noise, eye protection and brain protection, used with three primary color lamps, good color rendering, vivid colors, high luminous efficiency, low light decay, comfortable, clean work, study, living environment Improve work efficiency and help patients recover; especially suitable for places such as wards and examination rooms where lighting requires high color rendering.
3, security:
Because of its large power consumption, the inductance ballast converts heat into heat, and the surface temperature rises. Especially when the voltage fluctuation of the power grid is high, the temperature can reach 120~130°C, which is a potential fire hazard. Such accidents occur from time to time. Inductance ballast starts normal work above +10°C, and it is difficult to start below -5°C. It is difficult to normal start when the voltage of the power grid is lower than 180V. Since it cannot start once, it can easily damage the cathode of the lamp and shorten the life of the lamp.
Inductor ballasts have a low power factor of about 0.4 to 0.6, resulting in a large amount of reactive power that increases the lighting line current and the transformer capacity, thereby greatly increasing line and transformer losses, and also increasing power loss and lighting. Quality poses a threat to the operation of the power grid at the same time. After installation of the compensation capacitor, the harmonic current is significantly increased, thus causing interference and damage to the power grid and other instruments in the network. High-performance electronic ballast power factor ≥ 0. 97, only about 3% of reactive power loss, reactive power saving more than 45%; harmonic content is small, so that the input current waveform distortion is small, almost no pollution to the power grid; Reduce the capacity expansion of power supply equipment. The electronic ballast adapts to the wide voltage working range and can work normally in the environment of -10°C~+50°C, which is safe and highly reliable.
High-performance electronic ballasts have a protective effect on the lamp tube, the number of lamp switches can reach more than 10,000 times, and the lamp head is not obviously blackened. Besides guaranteeing the nominal life of the lamp tube, it can also prolong its life. .5 times.
4, environmental protection:
Because of the use of a mechanical starter, an inductive ballast generates instantaneous high-voltage pulses that interfere with household appliances and other electrical equipment. With an inductive ballast, the lamp life is shortened if the voltage is too high or too low. The waste lamp recycling will lead to mercury leakage and secondary pollution. High-performance electronic ballasts extend the life of the lamp, saving the cost and labor of replacing the lamp frequently, which is both economical and environmentally friendly.
To sum up, for the new construction and renovation projects, under the conditions of project fund operation and economic conditions, the ballast should be completely rejected.
