Equivalent Test Between Normal & High Frequency Fluorescent Lamp and LED Tube
Equivalent Test Between Normal & High Frequency Fluorescent Lamp and LED Tube
Comparing with traditional fluorescent lamp, the LED tube have high light effects, low power consume, long life time and stable luminous efficiency advantages etc. At the same time, for the LED tube performance testing is became more simple, in recent years more and more customers has chosen the LED tube to replace fluorescent lamp.
Due to the main lighting products are consist of traditional fluorescent lamp, like the CFL and fluorescent lamp are still occupy a large part of market, it's impossible to replace all of them immediately, specially at the business centre and market still have many fluorescent lamps and compacted lighting products; if replace all fluorescent lamp to LED tube, it's need lots of tome and huge cost, the most important is this way can't be approved. In order to make replacement work more effective, the IEC issued the IEC62776 standard dated December of 2014, this standard explain how to do equivalent test between normal & high frequency fluorescent lamp and LED tube. Before large scale replace fluorescent lamp to LED tube, we have to make sure the LED tube whether can turn on and meet lighting demand, the lighting demand have two points: the first is require the LED tube have lower power consume than fluorescent lamp; the second is based on consume same power, the LED tube have to higher light effects than fluorescent lamp, so we will discuss the comparison test between fluorescent lamp and LED tube. The below is IEC62776 standard and equivalent test explanation:
The IEC62776 standard from chapter 1 to chapter 3.2 are mentioned the LED tube can replace the double-capped fluorescent and how to use G5 and G13 lamp holder fluorescent lamp turn to LED tube, this kind of equivalent replacement needn't LED tube to do any change, this standard only talk about G5 and G13 lamp holder of LED tube(1 Scope). At the same time, this standard also mentioned the IEC60081 double-capped fluorescent lamp performance test and LED tube suitable replace fluorescent lamp with integrated magnetic ballasts. How to do equivalent test between LED tube and fluorescent lamp, there will be use a high frequency power supply and high frequency adjustable reference ballast. As we knew the fluorescent lamp is consist of fluorescent capillary, electrical ballast and fixture, the IEC60081 and IEC60901 both standards have clear explanation for how to testing fluorescent capillary. The testing process is connect RB-3 with double-capped of fluorescent capillary, also we need connect HFP-800 high frequency power with double-capped of fluorescent capillary, some of fluorescent capillary need to do preheating process according to IEC standard's requirement, as below picture. At the same time, the relevant parameters need set up according to IEC standard’s requirement.
We can learn more details on the article here：http://www.lisungroup.com/article-id-65.html. For the equivalent test between fluorescent lamp and LED tube, actually, it's take away the fluorescent capillary and connect LED tube(included driver) with EB, it's have necessary to explain the working principle of EB and driver: the EB is AC to AC model, when turn on the fluorescent lamp, there have a AC model high voltage to electric shock fluorescent capillary for lighting lamp, then the EB will output constant AC voltage to maintain the fluorescent lamp is always lighting on; the LED driver is AC to DC model, there have a DC power to lighting on singled LED or LED luminaires. So there use a LED tube(included driver) connect with EB which also keep AC to AC model, the equivalent test have three purposes: One is lighting on LED tube; Second is see whether the power consume of LED tube is lower than fluorescent lamp or not; third is light effect of LED tube is higher than fluorescent lamp(this will be judge by spectrometer & integrating sphere system). If need use best fair way to assess these three purpose, the EB is important, we can't use any of EB to do this kind of equivalent test, this EB must be mentioned or recommend by IEC or other standards, to solve this issue, Shanghai Lisun Electronic office developed HFP-800 High Frequency Power Supply and RB-3 High Frequency Adjustable Reference Ballast, both device are fully meet IEC60081 IEC60901 and ANSI C78.81 & C82.11standards. As we know the reference ballast is special designed for select reference light(fluorescent capillary), the characteristics of reference ballast have constant voltage and current ratio based on rated frequency, and it couldn't have any affected by voltage, temperature and ambient changes. The RB-3 is application with no sense of resistance ballast, the HFP-800 provide high frequency reference ballast with pure and high frequency power supply. The HFP-800+RB-3 system not only can to do T5/T8 fluorescent lamp test, but also can to do LED tube equivalent test.
Finally, we can see the difference of fluorescent lamp test and LED tube equivalent test. According to standard’s requirement, for the fluorescent lamp test, there must use relevant device, set up preheat current and preheat time to lighting on fluorescent lamp(As picture 1 show). Due to LED tube is special, when to do connection, we needn't this device(As picture 2 show):

Development of OLED Equipment Manufacturing Technology
Development of OLED Equipment Manufacturing Technology
OLED (Organic Light Emitting Display) is a new generation of flat panel display technology after LCD, LED, CRT and PDP (Plasma Display Panel). It has significant new industry characteristics. OLED is a new type of pure solid (CRT and PDP), which is a new type of pure solid (and LCD) with advantages of LCD and CRT. Besides, OLED has advantages of self luminous (no back light source), simple structure, ultra thin, fast response, wide viewing angle, low power consumption and flexible display, etc. It is known as "fantastic display technology" (view Table 1 and Table 2).

OLED two major application markets is for display and lighting, which is to show the development of the application is more rapid. Today, display technology of OLED need to overcome some challenges to have a real impact on the market. First of all, the OLED display manufacturing process is not yet matured, large size screen is difficult to mass production. With the increase of the size of the OLED display, the loss of the finished product rate and the loss of the manufacturing are also increasing. Secondly, the service life of OLED display material still needs to be further improved.
According to the drive mode classification, the OLED device can be divided into passive drive (also known as passive drive, PM-OLED) and active drive (also known as active drive, AM-OLED). PM-OLED device does not use thin film transistor (TFT), generally applied to small and medium size display. AM-OLED device is suitable for large size display, especially for large size full color dynamic image display. Compared with PM-OLED, the new display which we say is usually AM-OLED, which has the characteristics of fast response speed, wide angle of view, and has more application fields. Compared to the traditional TFT-LCD LCD panel, the AM-OLED panel has many advantages, such as thin body, high contrast, rich color, high resolution, wide visual angle, low power consumption and so on. In addition, because the OLED panel has no liquid molecules, the seismic performance is better, low temperature resistance, strong and durable. At the same time, compared with millisecond response TFT-LCD panel, AM-OLED panel response time is its thousands of tailing and dynamic picture jitter problem does not appear to. Therefore, AM-OLED has been the industry consensus as a new type of flat panel display technology". At present, the application of the small and medium size AM-OLED panels in the high-end mobile phone is a foregone conclusion, but it is not enough to produce a revolution in the large size TV.
Generally speaking, OLED manufacturing equipment mainly include: organic vapor plating and packaging of the passive organic light emitting display (PM-OLED) with key equipment, sputtering, plasma enhanced chemical vapor phase deposition (PECVD) system, vacuum thermal evaporation system (VTE) etc. AM-OLED has thin film transistor (TFT) thin film deposition apparatus, coating machine, exposure machine, dry and wet etching machine etc. AM-OLED TFT graphics making equipment, annealing furnace, annealing gas pipeline, laser annealing equipment of AM-OLED with TFT annealing equipment, TFT electrical test equipment, OLED optical test equipments AM-OLED test equipment, laser repair machine AM-OLED with defect detection and repair equipment etc..
2011 OLED technology progress rapidly, and in 2012 will be AM-OLED production technology has reached the mature and applied to large-scale panel production began. Over the next ten years, OLED technology will continue to flourish, especially in organic light emitting materials, organic coating material, circuit drive way and encapsulation technology has pretty good progress. Although the current OLED maximum production of glass substrate for 5.5 generations, but the 5.5 generation of the production cost structure is not clear. With the gradual maturity of AM-OLED technology, AM-OLED panel manufacturers will begin to import production in large size applications.
