A series of flat shaped LED light engines with a heat-transfer solution

摘要

We released 12 types of LED Light Engines (LLEs) as new flat shaped LED lamps on April 2011. They are differentiated in accordance with luminous flux, color temperature, beam angle and input voltage. These LLEs have large luminous flux of 1100 lm and 1600 lm with a heat-transfer structure which makes it possible that the heat generated by LED module is transferred to heat sink efficiently. In addition, since each LLE has a reflector and an electronic control gear in itself, it is expected that these LLEs make luminaries be designed more freely and compactly. This report reveals the features of these LLEs in detail.
