Samsung Electronics has achieved a major upgrade in its industry-leading performance levels for high-power LED packages. The efficacy of Samsung’s LH351B package that features 173lm/W (85℃, 350mA) has improved 8% over last year’s record performance. This new efficacy level extends Samsung’s leadership in high-power LED packages.
The highly reliable LH351B has a high lumen density and has been optimized for outdoor lighting applications such as street lights and security lights, where high-performance lighting is needed over extended periods of time and where efficiency and reliability are crucial. In addition, the compact Samsung light source simplifies the designing of solutions using a second optic lens, making it also suitable for high-density street lighting with complex lighting distribution designs.
With Samsung’s proprietary TZ chip structure and exclusive PSS (Patterned Sapphire Substrate) technology, the LH351B delivers exceptionally high brightness, and offers outstanding operating voltage through an electrode structure that provides even distribution of current. Furthermore, Samsung film phosphors in the LH351B help to achieve outstanding color stability.
Samsung’s LH351B has an expected lifetime of 280,000 hours at 105℃, 1A.
