• 7 Mistakes That Can Cause LED Driver Failures

    LED lighting industry has been booming for several years and it is well recognized that LED driver is the key component of LED lights. Usually the quality and right application of LED driver determines the reliability and life of the whole light fixture. So it is very important to make sure that fixture designers are fully aware of the possible failures caused by improper usage of LED drivers. Today we listed several possible reasons as below. 1. Not considering the higher Vf during the lamp cold start. The maximum output voltage of LED driver needs to be higher than Vfmax*N (N is the LED chip number in series). So please pay attention to the Vf max rather than Vf typ when choosing the drivers. And normally the drivers have 5%-10% output voltage margin from Vomax to the no load protection voltage to make sure of the cold start. 2. Not checking the derating curve provided in the driver datasheet. Normally LED manufacturers provide both Ta and Tc information in either product label or datasheets. If the driver is fully attached to heatsink, Tc is the key parameter worth paying attention to. Tc has to be less than the maximum rating to make sure of the right driver output without triggering the over temperature protection. And if the driver is independent and discrete from the light fixture, paying attention to the operation ambient temperature is normally enough and this is easier than monitoring the Tc. Also, the input voltage affects the derating curve because of the higher input current in the low input condition. 3. Improper startup which usually occurs in the lab. Normally the 90-305Vac driver is able to work in lower input voltage down to even 70Vac, but the thermal performance will be very poor thus triggering the over temperature protection or under voltage lock out. So it is suggested starting the driver after the input voltage is fully setup, rather than gradually increasing the input from low voltage. 4. Input Over Voltage. Need to make sure that the input voltage does not exceed the maximum rating, which normally 305Vac or 528Vac. We once had a failure caused by the improper startup in the real tunnel light application where the power was from the generator, and the operators turned on the generator after wiring all the lights directly to the generator, then all the 1000pcs of drivers were destroyed by the strong overshoot of the generator. While the right method should be: turn on the generator first, and then connect the lights to the power though a switch. 5. Connection. The wiring of L/N/G, output and dimming cables should be correct, and normally the input cable is brown, blue and green (green/white) for VDE cables and black, white and green for UL cables. Most of the dimming cables are violet/purple and grey. Carefully checking the label can avoid the problem. 6. Dimming problems. 0-10V dimmer usually output 1V as min and 9V as max when the source current from the driver Vdim+ is proper. If the dimmer can not reach 9V, t...

  • How do LED filament work?

    What are LED Filament Bulbs? Filament LED bulbs usually looks like a traditional glass light bulbs. The yellow strip that provides the light, was created to look like the filament of an incandescent light bulb, hence the term LED filament bulb. The original LED filament bulb was intended to mimic the appearance of the original Edison light bulb, you can see in the image how the two compare. How Do LED Filament Bulbs Work? The LED filament is composed of a metal strip with series of LEDs aligned along it. A transparent substrate, usually made from glass or sapphire materials is used to cover the LED’s. This transparency allows the emitted light to disperse evenly and uniformly without any interference or light loss. The LED’s on the filament strip actually emit a blue coloured light so an even coating of phosphor in a silicone resin binder material is placed over the glass to convert the blue light generated by the LEDs into a more preferable colour. Different phosphor colours can be used to change the colour of the light. For example, the more yellow the phosphor, the more yellow and warm the light becomes. This is how the the different colour temperatures are created. The major benefit of this design is the ease with which near full ‘global’ illumination can be obtained from arrays of filaments. Another positive benefit is better heat dissipation over traditional designs, due to the LED’s being more spread out, rather than densely concentrated. This in turn can lead to increased lifespan. Main Features of Chenxin Filament Range. 360 Degree Beam Angle: The clear glass cover and long LED filament make it possible for this bulb to provide a wide 360 coverage of warm light. Matching Dimensions: The LED filament bulbs are designed to the same dimensions as traditional filament bulb, so replacing they couldn’t be easier! LED Efficiency: They may look like retro style filament bulbs but they are packed with the latest LED technology and offer more than 100lm per Watt in energy efficiency. Standard and Dimmable: Our standard filament range are all flicker free and we also supply select lines in fully dimmable versions so you can turn the brightness down and turn the atmosphere up! Style and Shapes: the new filament range comes in a wide range of shapes and fittings, so you can find the style that’s right for you.

  • LED downlights are practical and economical

    LED downlight is a kind of embedded in the ceiling under the light of the lighting type lighting. LED downlight is a directional lighting, only its opposite surface can be received, the beam angle is focused, the light is more concentrated, bright and dark contrast. LED Downlights More prominent by the object, high luminosity, but also bring out a quiet atmosphere of the environment. LED Downlight Applicable to all places: In recent years, more and more offices and even families have used LED downlight lighting. Because the LED downlight used in the applicability of indoor lighting more and more people know, more and more people are welcome. LED downlight with some other lamps can not match or even other LED lamps can not match the applicability of indoor lighting LED downlight does not occupy the interior space, in the indoor installation of LED downlight, because the light of the confidentiality, will not use the feeling of oppression, LED Downlights on the contrary will produce a warm effect. Therefore, home improvement can choose to install more light downlight, reduce the sense of space pressure. And generally in the hotel, family, cafe, shopping arcot LED downlight use more. Downlights are generally used in shopping malls, offices, factories, hospitals and other indoor lighting, easy to install for people's favorite. LED downlight inherited the advantages of all the traditional downlight, the heat is small, long life, maintenance costs are minimal. Early LED downlight due to the expensive LED lamp beads, LED Downlights the overall cost is not high for customers to accept. With the LED downlight chip prices and cooling technology to improve the LED downlight into the commercial field has laid a solid foundation. Use LED downlight to make home improvement more beautiful. LED Downlights to help maintain the overall unity of the interior and perfect, do not destroy the chandelier and other lighting settings, light hidden in the interior decoration, not exposed, no glare, LED light source gives the visual effect is more gentle and uniform. LED lamp longevity: LED lamp life of 50,000 hours, six hours a day, is 20 years of life. This can reduce the purchase of lamps for a considerable amount of cost.
