Bridgelux LED arrays provides Vero

by / Monday, 12 May 2014 / Published in Company Blog
A new approach to the packaging in which the network of COB is made separately from the body plastic is one of the innovative aspects of the last family Bridgelux LED arrays .
Bridgelux Calif.-based Livermore, a family Vero LED matrix , which revealed ” new developments in design flexibility , ease of use and energy efficiency,” the company said. Vero is also a flat platform that will enable future opportunities for integrating smart sensors and wireless communication technologies .
Over existing networks Bridgelux LED , Vero family provides increased lm / W to 20% , a higher flux density and a simplified installation process , optimizes production and improves the reliability of the system as a whole.
Vero – platform four form factors (Fig. 1) with the output of 800 lm in warm white (3000K ) to 20000 lm in cool white (5000K ) are available. There will be several CCT and CRI options , including the option of 97 CRI product design. Vero platform is currently being evaluated by Bridgelux customers and will be available commercially in the first quarter of 2013.
The company says the new platform Vero , manufacturers can “significantly reduce inventory of electronic and optical components. ” Ranges too wide input current optimize product developers on the effectiveness , cost and light output .
Packaging and connectivity
A remarkable aspect of the platform immediately Vero is that the products are manufactured in two parts, with the matrix COB separated from the plastic body (see 2) . However, the two parts together as Velo product sold to customers , even if the customer has to buy the connectors separately.
There are a number of advantages to this approach. The board metal base is small and can be achieved with superior throughput and capacity , Bridgelux . The same plastic body is used for each matrix of a given size , regardless of the CTC or IRC .
Most of the production process – construction of the tables in COB and combines it with the mold material component – . Automates network – Configuration body also makes it easier to obtain the feature in the future, intelligent sensors or wireless – Add the broken communication , for example.
” The Vero product is to reduce the costs of highly automated processes , and can be easily upgraded for future intelligent applications do ,” said Jim Miller , Director of Sales and Marketing for Bridgelux . ” Vero table provides our customers design skills and production , they open up new design possibilities need while ultimately lead a more rapid adoption of LED lighting. “
Another important characteristic is an improved flexibility in the electrical connection which can be produced either by means of a welding edge connector Molex , or solder bumps provided on the plastic body ( as shown in FIG 2 ) . Soldering is much simpler because the solder bumps are thermally isolated from MCPCB and heatsink .
Details Array
The architecture of the COB has been redesigned so that the chips are sitting in a radial pattern and not on a square grid . This improves the filling and the quality of the optical beam . Overall, the products have a much higher density of light in the current game . The diameter of the circular output surface of light ( LES) varies from 10 mm to 29 mm as shown in Figure 1 .
Bridgelux developed the product to run in Vero current ” industry standard ” , eg 350 , 500, 700 or 1000 mA. Operation at higher through re – design of the circuit configuration of the activated chip voltage . In these current values ​​, the Vero tables are compatible with a variety of standard drivers .
Vero Tables are also compatible with a wide range of optical components. All this provides manufacturers with greater flexibility and more options than normal to reduce development time products shortening , reduce inventory and costs, says Bridgelux .
