Light emitting diode
Abstract
Abstract Translated from Japanese (57)【要約】 【目的】 LEDの樹脂に波長変換材料を含有させて発 光チップの波長変換を行う際、まず変換された発光の集 光をよくしてLEDの輝度を高めることを目的とし、ま た蛍光顔料を使用した際、波長の異なるLEDを近接し て設置しても混色の起こらないLEDを提供する。 【構成】 LEDの封止樹脂が、カップ3内部を充填す る第一の樹脂11と、その第一の樹脂を包囲する第二の 樹脂12とからなり、第一の樹脂11には発光チップの 発光波長を他の波長に変換する蛍光物質、または発光波 長を一部吸収するフィルター物質等の波長変換材料5が 含有されていることにより、波長変換光がカップ3に反 射されるため輝度、集光効率が向上する。 (57) [Abstract] [Purpose] When the wavelength conversion material is incorporated into the resin of the LED to perform the wavelength conversion of the light emitting chip, firstly, the purpose is to improve the condensing of the converted light emission and increase the brightness of the LED. Further, when a fluorescent pigment is used, there is provided an LED that does not cause color mixing even if LEDs having different wavelengths are installed close to each other. The LED sealing resin is composed of a first resin 11 filling the inside of the cup 3 and a second resin 12 surrounding the first resin. Since the wavelength conversion material 5 such as a fluorescent substance that converts the emission wavelength to another wavelength or a filter substance that partially absorbs the emission wavelength is included, the wavelength-converted light is reflected by the cup 3, so that the brightness and concentration are improved. The light efficiency is improved.
