Crystal photoelectric zhang said, the current production of MLCOB products photosynthetic efficiency is 160 lm/w, in the laboratory data of more than 200 lm/w. At the same time, COB MLCOB incorporated other advantages. For example, good heat resistance, thermal resistance can reach 5 ℃ / W MLCOB, convenient installation, no heat damage.
“And traditional COB difference is MLCOB glance with unique designs, and adopted the prism secondary optics processing. These two technologies combine traditional COB technology comprehensive application, the photosynthetic efficiency of the MLCOB’s products on the basis of traditional increased by 30% to 30%.” MLCOB high-end market, zhang said, will be focused on the future demand for LED lighting application of the main high luminance, high reliability, high heat dissipation.
Crystal photoelectric machine research and development director Zhang Mao can pitch meeting pointed out that the current influence LED products into the interior lighting factors include price, reliability, standards and performance.
At the meeting, and he also introduced EMCLED (EpoxyMoldingCompoundLED) products, including 2835, 3014, 3020, 3030, four mainstream specifications for devices.
Among them, the power in the 2835 products with a new seal structure, with heat sink design; Can be realized in the 0.2 w and 0.5 w high power product packaging; High photosynthetic efficiency high brightness, light efficiency can reach 120 lm/w; Small volume, LED finished product configuration can be more intense, the application of the light effect more uniform, etc.
LED packaging technology ten big trend
In pitch, crystal photoelectric Gong Wen, general manager of domestic LED packaging technology for the future made summarized ten trends and hot spots:
1, the power into the mainstream packaging way. Products currently on the market for high power LED products or small power LED products, though they each have advantages, but also is an insurmountable defects. And combined with the advantages of both power LED products arises at the historic moment, the mainstream packaging way.
