Abstract: A device for the injection of CMP slurry used in chemical mechanical polishing includes a main body and an outputting member. The main body has an applying end and is configured to be driven to swing over a to-be-polished surface. The outputting member has a channel a plurality of spraying holes communicated with the channel. The channel extends along a central axis. The spraying holes are arranged on the outputting member along a route, and each of the spraying holes faces the to-be-polished surface. The outputting member is pivotally connected to the applying end, so that slurry flows in the channel and is delivered to the to-be-polished surface through the spraying holes. The device for the injection of CMP slurry can evenly distribute the slurry and properly control the slurry in terms of using amount, direction and coverage, and is easy to clean and maintain.

Abstract: The present invention relates to an LED lamp comprising a bulb-shaped outer shell, a lamp plate assembly and a lamp socket. The bulb-shaped outer shell is formed of two half shells which can be bonded with each other in a left-right direction. Each of the two half shells has a groove on an inner surface thereof. The lamp plate assembly comprises a substrate, a plurality of first LEDs, a plurality of second LEDs and a conductive wire. The substrate comprises driving circuit elements and is inserted into an annular groove that is defined by the grooves of the two half shells. The substrate has a first surface and a second surface opposite to the first surface. The plurality of first LEDs and the plurality of second LEDs are respectively mounted on the first surface and the second surface of the substrate along a periphery of the substrate. An end of the conductive wire is electrically connected to the substrate.
