filling and packaging resin

Ever since Edison invented the light bulb which light up the world, there have been many significant evolutions in this field, but the biggest lighting revolution over the years is the LED (Light Emitting Diode) which has become a very important product in our daily life. To be sure it is also the most potential lighting product in 21 century.

In the past, LED's were used only as indicating lights, display signal lights. But nowadays with advance of technologies, they have gradually become a potential future star in the lighting market.

LED's have many advantages such as energy saving, compact, long life, so after commercialized in 70's, they were developed in high brightness, multi-colored, and with color LED's application in mobile phones, LED of high intensity blue light and white light SMD are used in great number. The potential of being used in cars and in in-door lighting is also unlimited. It is our hope to share with you our latest technology.

LETBOND has been working in this field for many years; we fully know what the industry needs. With our complete series of packaging materials, we are confident we can serve you as you required and to become your best partner.
