摘要:
In order to improve the color and luminance uniformity of an LED chip with a phosphor-containing resin sheet obtained by adhering the phosphor-containing resin sheet to the LED chip, improve the ease of production, and improve the degree of freedom in design, etc., provided is a resin sheet laminate provided with a phosphor-containing resin sheet on a base material, wherein the phosphor-containing resin sheet is divided into a plurality of sections.
摘要:
The present invention is a sheet used for LED encapsulant, etc. , with the objective of providing a sheet with excellent light resistance or of providing a phosphor sheet in which the optical properties thereof are not impaired and which exhibits excellent film thickness uniformity even when comprising large-sized phosphor particles in high concentration. The constitution of the present invention is, in one embodiment, a phosphor sheet in which the content of phosphor is 53 weight% or more of the total sheet, and in another embodiment, a phosphor sheet characterized by comprising at least a silicone resin, a phosphor and silicone fine particles.
摘要:
A phosphor-containing sheet having a storage modulus of 0.1 MPa or more at 25°C and a storage modulus of less than 0.1 MPa at 100°C, wherein a resin main component of the phosphor-containing sheet is a crosslinked product formed by subjecting a crosslinkable silicone composition containing a specific composition to a hydrosilylation reaction. This phosphor-containing sheet provides a phosphor sheet having good shapability and high adhesive power as a phosphor sheet bonded to an LED chip as a wavelength conversion layer.
摘要:
A phosphor-containing cured silicone that is a cured silicone which has a structure represented by general formulae (1) and/or (2) and also has units selected from general formulae (3) and/or (4), the phosphor-containing cured silicone includes a phosphor and particles having units selected from general formulae (3) and/or (4) :
wherein R 1 to R 3 are each a hydrogen atom, a methyl group, an ethyl group or a propyl group; X represents a methylene group, a dimethylene group or a trimethylene group, and may be the same or different; and R 4 to R 6 are each a substituted or unsubstituted monovalent hydrocarbon group, and may be the same or different. An object of the present invention is to provide a cured silicone in which a phosphor is uniformly dispersed, the cured silicone is characterized in that a silicone material has good thermal resistance and lightfastness. In addition, an object of the present invention is to provide a process for production of an LED-mounted substrate by which a plurality of LED elements can be continuously mounted in a batch manner.
