Abstract: A searching method for product photograph is provided. An input image is provided and delivered to a server from a client terminal, and the user selects a searching option from the client. According to the selected searching option, the input image is analyzed to obtain searching data. A comparison process is performed by comparing the input image and the searching data corresponding to the input image to a plurality of product images and a plurality of properties corresponding to those product images. At least one of those product images is delivered to the user for displaying.

Abstract: An operating method for modifying a 3D model in Augmented Reality (AR) on a mobile device includes performing, through the mobile device, a mobile application, wherein the mobile application provides a user interface configured to present a 3D environment image and a 3D model in AR, provide a modification function for adjusting one of a size, an angle, and a location of the 3D model in AR in the 3D environment image, and provide a confirm function for recording parameter data corresponding to the adjusted one of the size, the angle, and the location of the 3D model in AR; and transmitting the parameter data to a server to serve as updated parameter data corresponding to a AR application, so as to allow the server to update parameter data corresponding to the AR application in the mobile device according to the updated parameter data in the server.

Abstract: A light emitting diode (LED) lamp has a seat with a base, a cover mounted on the seat, and an AC fan, a heat sink and an AC LED light source mounted in the seat. The AC fan and the AC LED light source are electrically connected to the base of the seat. An AC directly provides to and drives the AC fan and the AC LED light source and no converter module is needed. Therefore, the LED lamp is quiet, energy saving and has good heat dissipation and low manufacturing costs for a prolonged operating life.
