The Development Process of LED Tube Lighting

The Recent Situation of Development of LED

Starting in 2000, in low the light flux of special lighting applications.LED, industry of the middle reaches are hitherto unknown value, further downstream of the packaging technology and industrial development, with different packaging structure forms and sizes, different light emitting colors tube core and double color, or color combination, can produce a variety of series, varieties, specifications of the products. Since the last century in ninety, LED chip and materials technology research and development has made a number of breakthroughs, the transparent substrate trapezoidal structure, texture, surface structure of flip chip structure, commercial super high brightness (above 1CD) red, orange, yellow, green, blue LED products have asked the city.

The Development of T8 LED Tube Lighting

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.

The Development of LED Tube Lights T8

The LED chip and the package no longer along the Gong traditional design concept and mode of production, the increase of chip light output, and is not limited to change material within the amount of impurities, lattice defects and dislocations to improve internal efficiency, at the same time, how to improve the core tube and package internal structure, enhanced LED internally generated photon emission rate, improve light effect, solve the heat, and light and heat sink optimization design, improved optical properties, accelerated surface mount SMD process is the mainstream direction of industry development. Enter after twenty-first Century, the led tube lights t8 for high efficiency, high brightness, full color change ceaseless development innovation, red, orange LED light effect has reached 100Im / W, 501m / W green LED, only LED luminous flux reaches tens of Im.
