Abstract: The present invention relates to a novel benzopyran derivative useful for preparing a drug for treating cancer, and more specifically, to a novel benzopyran derivative which is a micromolecule having a macrophage inhibitory effect and is useful for preparing a drug for cancer treatment. The drug particularly inhibits the differentiation of immune macrophages to stimulate the immune system, and thus is useful for treating immune-related cancers.

Abstract: A light emitting diode apparatus is provided. The light emitting diode apparatus includes a wavelength conversion layer, a light emitting diode layer, a light transmission layer, and a sheath layer. The wavelength conversion layer has a first refractive index. The light emitting diode layer includes a base layer arranged on the wavelength conversion layer, and a light emitting structure layer arranged on the base layer. The light transmission layer is arranged on the wavelength conversion layer, surrounds a sidewall of the light emitting diode layer and contacts the sidewall of the light emitting diode layer, and has a second refractive index. The sheath layer is arranged to cover the light emitting diode layer and the light transmission layer, and has a third refractive index less than the second refractive index.

Abstract: A light-emitting diode (LED) package includes: an LED having a polygonal shape in a plan view; a light-transmissive layer directing light from the LED in an upward direction; a wavelength conversion layer changing a wavelength of the light emitted through the light-transmissive layer; and a coating layer covering the light-transmissive layer and reflecting the light emitted through the light-transmissive layer in the upward direction. In a plan view of the light-transmissive layer, a length from a first point corresponding to a vertex of the LED to a second point corresponding to an end of an extension of a diagonal of the LED is greater than or equal to a length from the first point to a third point corresponding to an end of an extension of a side of the LED.
