The LED product package structure types also have according to the light color, chip material, luminance, size, feature classification. Single tube core generally consists of point light source, a plurality of die assembly generally be a surface light source and a linear light source, as indicative of the state information, and display, light emitting display with multiple die through the die, the appropriate connections (both series and parallel) with suitable optical structure which is formed by the combination of light, composition the light emitting section and a light point display. The t8 led tube lighting
is also developed by this technology. Surface mount LED may gradually replace the pin type LED, application design is more flexible, is displayed in the LED market occupies a certain share, have accelerated development trend. Solid light source are part of the product will be listed, in LED, long-term development direction.
