LED light source packaging technology innovation

LED light source packaging technology for innovative design is the key to the rebirth of LED lighting. Most of the current LED lamps with low operating voltage (VF = 3.2V), high current (IF = 200-700mA) low-voltage LED lamp beads (LVLED). LED lamp beadwork, only 30 % of the electrical energy into light energy, 70% of the energy is converted into heat, so the heat LED lamps if done well, a lot of heat accumulation of the lamp chamber is always in high-temperature environments, switching constant current power supply electrolytic capacitor will be due to high-temperature electrolyte depletion, leading to failure; LED lamp beads in a high-temperature environment of long-term and premature aging occurs.

The birth of HVLED ( high voltage LED) lamp bead technology to indoor LED lighting brings new vitality, new ideas, new design ideas. Thus will be born a lot of whimsy LED lighting new products, new lamps. HVLED's biggest feature is the high voltage (VF = 50-280VDC), low current (IF = 20-60mA), with the same power LVLED light board compared to its much lower heat. HVLED is the N series satellites Low LED die in the package into a pressure module, its application is very convenient.

Innovative LED packaging technology is based on the filament column HVLED concept and developed. The N pieces of low-power LED package to die in series on a glass substrate, becomes different from the previous new package.

The N pieces of small power LED die is encapsulated in a glass column directly to the substrate. For example, each of the 28 pieces of 1016LED 0.02W die package in the long 38mm, diameter glass column base 1.5-1.6mm, using gold wire series. This LED VF filament column = 3.2X28 = 89.6V, IF = 10mA. The most important feature of LED filament column is the 360-degree angle of light, high- voltage (75-90VDC), low current (10-15mA) driver working condition; using high -quality LED die can produce high-brightness (75-95lm), high light efficiency (120-130lm / W), high color rendering index (90-95Ra), high reliability LED filament column; blue and red LED die can mix and match different proportions to produce different color temperatures (2870-6020K ) the LED filament column. LED filament structure of the high-pressure column shown in Figure 3, the substrate is encapsulated glass column of blue + red LED die, according to pre-set rules of order, both ends of the extraction electrode, after a series of gold, yellow or yellow-green spray phosphor, all wrapped. Note that when energized high voltage protection test. Such LED filament column is working in a small 10-15mA current, low-power state, the whole column is floating filament LED full access to air, heat flow, the heat is very low. best led headlights http://bestledheadlight.com/
