Definitions
- the present application relates to a curable composition and its use.
- the optical element includes a light emitting diode (LED) which emits light when a current is applied, or a photoelectric conversion element that generates electromotive force when light is applied, and such optical element is usually encapsulated by an encapsulant.
- LED light emitting diode
- photoelectric conversion element that generates electromotive force when light is applied
- the epoxy resin which is high in adhesiveness and excellent in dynamic durability is used widely (for example, patent documents 1-3).
- the epoxy resin has a low transmittance to light in the blue to ultraviolet region and is poor in light resistance.
- EVA ethylene vinyl acetate
- EVA material is inferior in adhesion with other components in the module, and accordingly, when used for a long time, the interlayer peeling is easily caused, resulting in deterioration of efficiency, corrosion by moisture infiltration, and the like.
- the EVA material is less resistant to ultraviolet rays, so that discoloration or discoloration is easily caused, which also lowers module efficiency.
- the EVA material there is a problem that causes damage in the device by generating a stress during the curing process
- phosphors or the like may be mixed in the LED encapsulant in order to realize white light in a backlight unit (BLU) or an illumination using an LED, and a light converting material may also be used in the encapsulant of the photoelectric conversion element. This may be mixed.
- BLU backlight unit
- a light converting material may also be used in the encapsulant of the photoelectric conversion element. This may be mixed.
- a certain amount of inorganic particles for example, silica or the like may be added to the encapsulant. When the inorganic particles are added, physical properties such as heat resistance, crack resistance, and thermal shock resistance of the encapsulant may be improved.
