摘要:
According to one embodiment, an LED package includes first and second lead frames, an LED chip and a resin body. The first and second lead frames are apart from each other. The LED chip is provided above the first and second lead frames, and the LED chip has one terminal connected to the first lead frame and another terminal connected to the second lead frame. In addition, the resin body covers the first and second lead frames and the LED chip, and has an upper surface with a surface roughness of 0.15 μm or higher and a side surface with a surface roughness higher than the surface roughness of the upper surface.

According to an embodiment, a semiconductor light emitting device includes a insulating base and a semiconductor light emitting element and resin. The insulating base includes a first face, a second face opposite to the first face, and a side face connecting to the first face and the second face, a recess portion being provided on the side face extending from the first face to the second face. The insulating base also includes a first metal layer blocking an opening of the recess portion, a second metal layer on an inner face of the recess portion, and a third metal layer on the second face, the third metal being electrically connected to the first metal layer via the second metal layer. A semiconductor light emitting element is fixed on the first face; and resin covers the first face and seals the semiconductor light emitting element.

According to one embodiment, an LED package includes a first leadframe and a second leadframe mutually-separated, an LED chip and a resin body. The LED chip is provided above the first and second leadframes. One terminal of the LED chip is connected to the first leadframe. One other terminal is connected to the second leadframe. The resin body covers an entire upper surface, a portion of a lower surface, and a portion of an end surface of each of the first and second leadframes. The resin body covers the LED chip. Remaining portions of the lower surface and the end surface of each of the first and second leadframes are exposed on the resin body. First and second recesses are made between the remaining portions of the first and second leadframes. An inner surface of each of the first and second recesses is not covered with the resin body.
摘要:
The present invention provides a method for screening and evaluating ameliorants of dry skin caused by atopic dermatitis, comprising: evaluating a candidate drug as being an ameliorant of dry skin caused by atopic dermatitis in the case the candidate drug significantly increases expression and/or activity of bleomycin hydrolase in comparison with a control drug.
摘要:
The invention provides a screening method for chronic inflammation inhibitors or cancer metastasis inhibitors wherein, when a candidate substance as a chronic inflammation inhibitor or cancer metastasis inhibitor significantly inhibits binding between EMMPRIN and S100A9 or S100A8/A9, the candidate substance is evaluated as significantly suppressing chronic inflammation or cancer metastasis.
摘要:
The present invention provides a screening method for a substance capable of promoting recovery of skin barrier function, wherein the method comprises the steps of incubating caspase-14 and prosaposin in the presence of a candidate substance for the substance capable of promoting recovery of skin barrier function, and selecting the candidate substance as the substance capable of promoting recovery of skin barrier function when the degradation of prosaposin into saposin A is promoted significantly compared to a control substance.
