英文摘要 | The objective of the invention is to provide with a tunable LED module capable of easily selecting a wavelength and reducing particular parts, comparing to that of prior art. The tunable LED module according to the present invention is applicable to a certain short range communication. The module comprises: an LED 1 capable of emitting a light with a certain wavelength band including a desire wavelength; a collimator 2 for collimating the divergent light from the LED 1; an etalon 3 working as a wavelength selector for selecting a light with a plurality of wavelengths including the desired wavelength from the light emitted from the LED 1; a BRF 4 working as an optical tuner selectively tunable the desired wavelength within the wavelengths selected by the wavelength selector; an optical coupler 5, which the light rejected by the BRF 4 enters to and couples with; a LED mounting element 6 made from a material with a high thermal conductivity, such as cupper, cupper alloy, and the like, the element 6 for mounting the LED 1; and an optical receiver 7 for detecting the power of the light with wavelengths excluding the tuned wavelength and then generating light level monitor signal representing the power of the detected light. |
