Analysis of the option to purchase the power LED fluorescent reference factor
time2012/12/11
Domestic LED lighting market policies to promote, LED fluorescent tube lighting market is extremely strong, configuration design LED Tube manufacturers of fluorescent tubes LED power core components of LED Tube manufacturers procurement quality of the products of the time, if you choose to buy fluorescent lamp power do not fly, then create a lot of problems.
Part of the selection of the core components of the LED Tube Power Purchase requires special attention, the relevant purchase fluorescent lamp power reference as follows:
1: LED fluorescent lamp power need to choose to purchase LED constant current drive power. In order to ensure a stable current power supply LED fluorescent tube.
2: Choose very tricky LED power good LED power supply manufacturers to cope with the power LED light board match the pre-coordination, so as to make the fluorescent lamp power to get the maximum performance running.
3: Select a fluorescent lamp power supply need to be designed into a rated operating current of 16-18 mA, this is a more mature avoid excessive current trigger a severe fever occurs.
4: Buy fluorescent lamp power attention to the working voltage design, designed to 3.125V more reliable.
5: LED fluorescent tube power supply design Wide voltage LED light panel series and parallel work, such as: number of LED light board parallel to control recommended for 6/8/12 and the total current is controlled at about 240 mA for the best.
6: Choose to purchase LED power and actively coordinate with the LED power supply manufacturers LED series and parallel with PFC power factor and wide voltage relationship, because these factors will determine the actual cost of procurement issues. Three cases: a dedicated circuit with PFC power supply PFC, the PFC is generally about 0.65; One is with passive PFC circuit, each light board prepared well, PFC generally about 0.92; a do with an active 7527/6561 circuit, PFC 0.99, but the cost of this program is twice as expensive than the second program. More of the second scenario.
7: LED fluorescent lamp power supply with the optional power supply manufacturers communicate good constant current accuracy problems, ± 3% on it. The error of 3%, 6-way parallel, each of the error of about ± 0.5%, 12-way parallel, each of the error of about ± 0.25%, and so on.
8: Fluorescent lamp power is divided into isolated power with non-isolated power supply, according to the manufacturing led fluorescent tube, the actual situation to choose good power.
9: Reference good led power efficiency and power factor, power factor, the efficiency of these two indicators is sometimes mutual constraints and product output current to improve efficiency, output as high voltage, low current. Our company's internal control standards generally power factor 0.80-0.90 efficiency is 0.82 - 0.90. Our existing customers in the power factor and efficiency trade-offs generally tend to raise the efficiency of the main power factor above 0.80.
10: Note that you produce LED fluorescent tube and power with size configuration.
11: LED fluorescent tube products in recent years is engaged in exports is more frequent, the international market generally require CE certification also requires PSE certification, like the Japanese market. These authentication factors faced by the market under the product planning and communication.
Above 11 choose to purchase LED power reference factors, we can own the actual use of the LED Tube production and export destination and other factors to determine the trade-off choices.
