Light-emitting device

A light-emitting device includes a panel substrate, a light-emitting chip, and a light extracting layer. The light-emitting chip is disposed on the panel substrate. The light extracting layer covers the light-emitting chip and the panel substrate, and the light extracting layer has a side portion. Taking the position where the edge of the light-emitting chip is in contact with the panel substrate as the origin, the side portion and the origin define a circle tangential to the surface of the side portion. The circle has a radius c which satisfies the following formula (1): 1 40 ⁢ H ≤ c ≤ H ( 1 ) where H is a height of the light-emitting chip. The light-emitting device disclosed herein has a light extracting layer having a very small thickness, and provides excellent light-emitting efficiency and lifetime of the light-emitting device.

Slider for a cutter

A slider has an upper sliding element, a lower sliding element and a resilient tab. The upper sliding element has two protrusions laterally formed on and protruding from the upper sliding element. Each protrusion has an inclined pushing surface. The lower sliding element is combined with the upper sliding element and has a chamber and two through hole.
