Following the successful mass production of non-isolated stroboscopic fluorescent LED driver power, Delip Optoelectronics recently developed an isolated stroboscopic LED fluorescent lamp power supply series. The isolated stroboscopic LED fluorescent lamp once again provides strong technical support for the manufacture of LED luminaires, detonating a new wave of application of LED fluorescent lamps for healthy lighting.
Light pollution can be seen everywhere in our lives, such as stroboscopic, glare, ultraviolet radiation, electromagnetic radiation. Common lighting in home life. The main reason is the stroboscopic problem. For example, the fluorescent lamp commonly used in homes, the light will produce 100 times of light and dark changes per second, and the eyes need to be constantly adjusted to adapt to the frequency flash source. After a long time, the eyes will naturally feel tired. As a symbol of modern civilization, since people can't do without lighting, they can only work hard on healthy lighting and reducing light pollution.
Why strobe?
Most of the current LED luminaires are flashing, and there is no national standard to impose normative requirements on this. Only some foreign developed countries have individual needs for this, and have not formed the industry's mainstream awareness and normative standards. The reason for the stroboscopic phenomenon is that the LED light source needs to be driven and must be rectified, and the rectified current frequency is twice the AC frequency, that is, 100-120HZ, the general illumination eyes can not be seen, but the camera (camera) framing It is also frequency, so if there is a frequency cycle, there will be stroboscopic (ghosting, flickering). This is not a problem with LEDs, but a problem with LED driver power supplies used by luminaire manufacturers.
Strobe resolution
A high-brightness lighting application, such as an office, shopping mall, etc. In order to give full play to the advantages of LED lighting, LED driving power supplies need to have high efficiency, high power factor, low cost and long life. Conventional LED driving methods such as resistance current limiting, linear regulation and charge pump switching control are less efficient, while switching constant current driving power supplies have high conversion efficiency, power density and control accuracy, and are particularly suitable for use as high power LEDs. The driving power source of the light source. In the case of AC input, the high-power LED driving power supply generally consists of two parts: a conversion circuit and a driving circuit. Among them, the conversion circuit converts the alternating current into direct current and implements Power Factor Correction (PFC), and the drive circuit uses a special LED driving chip to provide constant current driving for the LED. Since the LED is positively ampere, it must work at the DC voltage, so whether the LED is stroboscopic or not depends on whether the driving current of the LED driving power supply is a straight DC current. There is a strobe.
Features:
• The UL8750 is being applied for EMC/EMI/EMS and LVD testing.
• Accumulated supply of 30,000 PCS, non-performing rate 1/1000 PCS.
• Proprietary stroboscopic technology.
• Design and supply the market mainstream LED type light source for customers, such as 3014, 2835, etc.
• DC30-43V/200-600MA is optional.
• Low cost, low harmonics (THD <20%), high efficiency (220Vac >85%)
