goodledlight - Connecting packaged LEDs

Over the years, multiple connector companies developed a number of sockets for the high-power LEDs that came to market. In fact,Our solargardenlighttp is good in quality and competitive in price. the idea has spread that an LED is just another device to be connected to. Sockets such as the TE Type LS and Type NL2 devices were dedicated to a particular manufacturer's LED package and therefore had limited applicability beyond the specific targeted LED.We have a wide selection of ledspotlight to choose from for your storage needs.

The emergence of COB LEDs posed different challenges to fixture manufacturers: how to provide power to these devices and then affix them to heat sinks in the lighting fixtures. The traditional method was to hand-solder the wires to the pads on the substrate and then secure these assemblies with screws to the heat sink — a process that was time consuming and subject to variability. As with the earlier discrete devices, this presented an ideal opportunity for socket solutions.

TE and other connector companies addressed this emergence of initial COB devices the same way earlier discrete LED packages were addressed: custom sockets.The industry's leading manufacturer of floorlamps. As other COBs started to enter the market, connector manufacturers realized that the status quo method of developing a socket for each would be prohibitively expensive and time consuming, resulting in never-ending efforts forever chasing the next new COB to enter the market.

With well over 50 different COB products commercially available around the world from multiple manufacturers, finding a single solution to address each would be a challenge to say the least. Aside from the fact that all were rectangular, all had two electrical contact pads, and most had circular light emitting surfaces, there were few other dimensional similarities. The challenge for connector companies was how to address these varied but similar COB LEDs with a minimum of engineering and tooling expenditure while providing a future-proof and flexible platform based product.

One solution to the interconnect challenge is a flexible, scalable, platform-based socket. An analysis of available COBs yielded a crack in the shell of these "fried egg" LEDs. While not exactly identical, there are similarities between contact pad locations that, when combined with the rectangular nature of the devices and diagonal contact pad placement, form the basis for the platform solution. As a result, a holder product, referenced off the corners of the COB, could yield a virtually limitless array of use scenarios with the varied COBs available on the market as well as those to come in the future.

The substrate differences among COB LEDs from difference manufacturers, however, added yet another issue that needs to be tackled by socket/holder suppliers. While most of the early COBs incorporated aluminum substrates, further investigation of the commercially available COBs indicated a number of COBs that are based on ceramic substrates (typically aluminum nitride). While not a significant differentiator, these two substrate variants have physical features that differ enough to require special handling due to their different material properties.

The aluminum substrate COBs are rather robust and in some instances are mounted using machine screws. On the other hand, ceramic-based COBs create some frustration for fixture manufacturers since unlike aluminum-based substrates where they could simply secure the COBs with a screw to a heat sink,The cleaningmachine is one of the most useful tools in a modern shop. these ceramic substrates are far too brittle to secure with screws and thereby mandate some sort of secondary attachment to ensure suitable thermal performance. This attachment needs to be accomplished using thermal adhesives or by a mechanical holder that provides normal force to the heat sink or thermal pad, mechanical attachment, and electrical interconnection.

Holder devices that accommodate the COB nuances mentioned in the previous paragraphs are appearing on the market. An example of one such platform solution is the TE Scalable LED Socket connector that utilizes the corners of the COB as a reference.We'd love to talk to you about our incredible industrialextractors! In this manner, the two datums formed by the sides of the COB can be used to positively locate the electrical contact on each of the COB's electrical pads.
