A), Compare with magnetic ballast, large efficiency and power saving: magnetic ballast operating frequency 50Hz, electronic ballast working frequency for 20~50KHZ, lamp at higher frequency luminous efficiency is 10% increased than that from the frequency, and electronic ballasts than magnetic ballast lighting brightness increase; other electronic ballast for its minimal electrical power consumption, this kind of as from the same brightness by electronic ballast magnetic ballast energy-saving than about 20-30%; the inductor ballast enhance indoor temperature rise summer season require cooling air conditioner electrical power is not really integrated during the calculation. Hospital general lighting accounts for about 70%, the use of higher effectiveness electronic ballast can conserve two to 3 months of electrical power, can gradually recover the price of light, and minimize the cost of residence operation.
B), comfort: ballast will generate stroboscopic phenomenon, on this setting, finding out visual fatigue. To the large pace rotating objects quick to produce the illusion, there exists a chance of accident. And magnetic ballast issued 50Hz noise, straightforward to create men and women irritable ent pay attention to phonic room inside the use of fluorescent lighting, use of electronic ballasts, to avoid misdiagnosis; ward, waiting hall within the use of fluorescent lamps, should not make use of the magnetic ballast, mostly consider the stroboflash and noise will lead to the patient’s discomfort. Utilization of electronic ballasts can eradicate the stroboscopic, eyesight safety, industry revenue from the college students help the eye lamp could be the utilization of electronic ballast outfitted trichromatic lamp design production. Electronic ballast with substantial performance and no stroboscopic, no noise, and eye and brain safety, and supporting the usage of trichromatic lamp, very good colour, vivid colour; high photosynthetic efficiency; minimal light decay; comfort; purification get the job done, review and living natural environment; to improve operate efficiency, advantageous patient rehabilitation; specially for in the ward, in the examining area lighting prerequisites significantly larger colour destinations.
C), safety: magnetic ballast because of its higher electrical power consumption, power consumption into heat, surface temperature rise, especially during the power grid voltage fluctuations, the temperature can reach 120~130 degrees, become a fire hazard, such an accident takes place. During the, the ballast can get started up at 10, and also the voltage is much less than -5, as well as the grid voltage is less than 180V, and it truly is not easy to start. magnetic ballast energy component is reduced, about 0.4~0.six, the result of the massive variety of reactive energy increases the lighting circuit and transformer capability, thereby enormously escalating the line and transformer losses, but additionally increased the power loss, minimize the lighting excellent, though the energy grid operation has appreciably elevated the harmonic existing, so the power grid and also other equipment from the network cause interference and harm. High performance electronic ballast energy component is better than or equal to 0.97, only about 3% from the non electrical power loss, no electrical power saving greater than 45%; harmonic articles is modest, to ensure that a smaller input latest waveform distortion, the grid virtually no pollution; and lessen the capacity of energy supply tools. Electronic ballast to broad working voltage array, can get the job done generally with security and in – ten DEG C ~ 50 DEG C surroundings, substantial reputable electronic ballast for higher effectiveness on the lamp tube has protective impact, lamp switch frequency of up to a million instances, lamp devoid of evident nigrescent, in addition to guarantee to attain the lamp nominal existence outdoors, but in addition to extend the life one.3 to 1.five instances.
