Abstract: A powder dispersing device of a powder particle size distribution measuring equipment has a base, an elastic force generating assembly and a first housing. The elastic force generating assembly includes a bumping piece, a force applying board and a power transmission assembly. Two ends of the power transmission assembly are respectively connected to the bumping piece and the force applying board. When the force applying board is applied with a first displacement, the power transmission assembly actuates the bumping piece to generate a second displacement which enables the bumping piece to have a first elastic force. The first housing is formed with a through hole on a side surface for one end of the force applying board to extend out. The first elastic force of the bumping piece triggers the bumping piece to strike on any surface facing toward the inside of the first housing and touching the other end of the bumping piece.

Abstract: A two-parallel-channel reflector (TPCR) with focal length and disparity control is used after being combined with an imaging device. A left parallel channel and a right parallel channel are formed in the TPCR, so that the imaging device can synchronously perform an imaging operation on a left side view and a right side view of a scene, so as to obtain a stereoscopic image. Each parallel channel is bounded by two curved reflecting mirrors, so that captured light rays may be parallelly reflected in the channel, and an operator may adjust a convergence angle and an interocular distance between the left side view and the right side view, so as to control the focal length and disparity during imaging as require.

Abstract: An optical engine of a light emitting diode (LED) light module comprises a heat dissipation device, an LED light bar and an optical component. The heat dissipation device comprises a base plate and a plurality of fin plates vertically welded onto a surface of the base plate. The LED light bar is disposed on an opposite surface of the base plate so that the LED light bar can dissipate heat through the fin plates. The optical component having a space for accommodating the LED light is provided to form a desired light distribution pattern.

Abstract: An LED lamp includes an illumination apparatus and a heat-dissipating waterproof cover. The illumination apparatus includes LED modules; and the heat-dissipating waterproof cover is configured to cover the LED modules. The heat-dissipating waterproof cover includes a plurality of drain members, and a gap is formed between every two drain members so as to increase the air convection, thereby increasing heat dissipation efficiency of the LED modules. Every two adjacent drain members are partially overlapping in vertical to prevent the intrusion of water.
