Problems solved by technology

However, if the phosphor is not uniformly dispersed in the liquid resin, color difference will occur in all semiconductor light emitting elements
In addition, when the liquid resin is supplied separately to the semiconductor light emitting element, it is difficult to keep the amount constant, and the thickness of the liquid resin tends to be uneven during the curing period, so it is difficult to maintain the amount of the phosphor disposed on the semiconductor light emitting element. must

Embodiment Construction

[0032] The resin sheet laminate of the present invention is characterized in that a resin sheet containing a phosphor and a resin is provided on an elongated substrate, and the resin sheets are repeatedly arranged in the longitudinal direction of the elongated substrate. block. Hereinafter, a resin sheet containing a phosphor and a resin is referred to as a "phosphor-containing resin sheet".

[0033] The blocks of the phosphor-containing resin sheet can be arranged in a desired shape, size, and number according to purposes. On the other hand, the base material supporting the blocks of the phosphor-containing resin sheet is integrated within the range of the plurality of blocks of the phosphor-containing resin sheet, and the blocks of the phosphor-containing resin sheet are not scattered separately. status.

[0034] In the resin sheet laminate of the present invention, since the blocks of the resin sheet in which the phosphors are uniformly dispersed are formed in advance wit...

Abstract

A resin sheet laminate which is provided with a phosphor -containing resin layer on a substrate, characterized in that: the phosphor-containing resin layer is composed of multiple subdivisions; the substrate has lengthwise and widthwise directions; and the multiple subdivisions are regularly arranged in the lengthwise direction of the substrate in a line. This resin sheet laminate can improve the uniformity of color or luminance of a semiconductor light-emitting element which has a phosphor-containing resin layer laminated thereon, the easiness of production of the element, the freeness of design thereof, and so on.

Description

technical field [0001] The present invention relates to a resin sheet laminate in which a phosphor-containing resin sheet is provided on a substrate. More specifically, it relates to a resin sheet laminate in which a substrate has a longitudinal direction and a width direction, and blocks of phosphor-containing resin sheet layers for converting the emission wavelength of a semiconductor light emitting element are repeated in the longitudinal direction Configured in columns. Background technique [0002] As far as light-emitting diodes (LEDs, Light Emitting Diodes) are concerned, in the context of significantly improved luminous efficiency, they are characterized by low power consumption, long life, and design. The market is rapidly expanding in the automotive field such as vehicle headlights, and in the general lighting field. [0003] The light emission spectrum of LED depends on the semiconductor material forming the semiconductor light emitting element, so the light emi...
