Failure COB LED lamps

LED has been globally recognized as a new generation of environmentally friendly high-tech light, its long life, high reliability is to get the majority of consumers. Although from a technical point of view LED chip theoretical life of up 100000H, but because of the package, driving, cooling and other technologies applied to the life of the light source or luminaire for general illumination class can only reach 30000H, there are many on the market even with less than six months the product will be a problem. How to improve the reliability of LED lighting products has also been a business problem to be solved.

Failure COB LED lamps

LED lighting product failure modes can generally be divided into: chip failure, package failure, failure of electrical stress, thermal stress failure, assembly failure. Through the analysis of these phenomena and the failure to improve, we can design and produce high-reliability LED lighting products to help. Based on the COB packaging technology and its application several common reasons for failure are analyzed and described the matter should be paid attention to summarize.

LED lighting products consists of three main components, namely cooling structure, power supply and lighting parts. Illuminated by the light source portion and a secondary optical light components (such as lenses, mirrors, and the diffuser plate) composed of

As LED lighting products in the light part of the core components, is the basis for achieving photovoltaic device performance. The technology is based on a package COB light source, which itself is no longer needed any automatic surface mount process, just to elicit positive and negative welding can be assembled into a simple matrix or lighting. Its important in LED lighting products key components.

These components are, in particular, COB, in most cases, are assembled by hand. This has resulted in the production process is likely to produce more than a potential failure in an automated process.

Based COB LED packaging technology is the multi-chip structure with different string and then wire bonding method to establish an electrical connection between the chip and the substrate, the final package from the use of encapsulants. This structure determines the interior of any single chip COB bad, will result in the remaining surplus chip current load increases, then rising single Vf value, the drive power supply into the output overvoltage condition, the output abnormalities lead flashing until the death of the remaining branches lights. The reason to exclude bad chip itself, in most cases the performance and poor inter-chip key, the key and our conventional single wire bonding into ABCDE five keys, and keys and poor I encountered following in time common reasons.

Audi universal LED intelligent headlamps

Then LED headlamps from halogen headlights to xenon headlights, auto headlights also with the application of new technologies constantly updated. Has a “lamp factory,” said the Audi brand, in this regard has been playing a leading pioneer in the trend. Prior to the launch of the new A8L models Audi is the first application of newly developed matrix LED headlamps, a number of intelligent application of technology to become a major highlight of the product. Besides access to information learned after: Audi expected future universal matrix LED headlamps, including A6, A7, TT, R8 and other vehicle models are expected to have facelift.

Audi universal LED intelligent headlamps

Matrix LED headlamps as Audi’s latest technological achievements, has taken the lead on its flagship models equipped A8L, the application of advanced technology, the product has become one of the most major publicity selling point. In addition the technology also will be its first application on a variety of products in the Audi, but because the cost of production and other factors limit the future will be considered, including the Audi A6 / S6, A7 / S7, RS6, RS7, TT, Q5, Q7 and R8 and so on higher-end models use this both the artistic and technological sense matrix LED headlamps will help Audi enhance the market competitiveness of its products.

When driving at night, use high beam irradiation general vehicle in front, while the Audi Matrix LED headlamps can fully dynamic lighting management. Once the light sensor detects the light beam emitted onto or across the front of the vehicle, it will automatically adjust or turn off a few lights LED monomers within the group, so that the front of the vehicle will not be LED lights direct impact highlighted. The user-friendly design can also contribute to vehicle safety.

Audi also increased matrix LED headlamps DynamicdisplaySignal dynamic cornering light technology, the system can control each LED lighting time and monomer sequence. In the new Audi A8L headlights, for example, the yellow LED turn signal composed by multiple groups, when lit from less to more continuous change, lit the interval between each LED is 20 milliseconds, can dynamically display steering direction, both the artistic and technological sense, but also improve the warning effect.

For pedestrian protection, the matrix LED headlamps also sets the number of stars for pedestrians ‘protection’ lamps. When the Night View Assist camera to detect pedestrians in front or animals, “protection” lamps will automatically send three strobe light to warn drivers and pedestrians of potential danger, and reduce the probability of accidents at night. This flashing is very humane, and not the way until the human eye, but can only shine on the place of the head or less.

In order to allow the driver to control the way information is clearly at night, Audi Matrix LED headlamps can use information from the navigation system to achieve at the corners, junctions and other conditions more specific auxiliary lighting. In actual driving conditions, for example, the Audi brand new matrix headlights illuminate traveling in the road, it is also able to automatically detect the roads prompt information such as speed limits, cut the line, cornering and other signs, a separate projection light, to cause the driver watch out.
