Abstract:
A light source device includes a first light source, a second light source, a reflective assembly, and a condensing lens defining an optical axis. The first light source includes a first lamp and a first reflector reflecting light beams generated by the first lamp as first parallel light beams. The second light source includes a second lamp and a second reflector reflecting light beams generated by the second lamp. The first light source, the reflective assembly and the condensing lens are arranged in order along the optical axis. The second light source corresponds to the reflective assembly deviated from the optical axis. The reflective assembly reflects light beams reflected by the first reflector back to the first reflector, and reflects light beams from the second reflector to the condensing lens. The condensing lens condenses the first parallel light beams and the light beams reflected by the reflective assembly.
Abstract:
An electronic device with a hidden I/O interface module is disclosed. The electronic device includes a container and a surface with an opening, container and the opening communicate with each other. The container includes a first position and a second position. The electronic device also includes an I/O connection unit, a pivot module and a cover. The I/O connection unit is disposed at the container, electrically connected to the electronic device and includes a connecting surface. The pivot module is connected to the I/O connection unit. The cover is connected to the pivot module. When the cover is shut, it covers the container and makes the I/O connection unit located at the first position. When the cover is open, it drives the pivot module to drive the I/O connection unit to move to the second position to make the connecting surface of the I/O connection unit aligned with the surface.
Abstract:
An antireflection film includes a first layer, a second layer, a third layer, a fourth layer, a fifth layer, a sixth layer, and a seventh layer. Each of the first, third, fifth, and seventh layer is formed using a low refractive index material. Each of the second, fourth, and sixth layer is formed using a high refractive index material. The thicknesses of the first, second, third, fourth, fifth, sixth, and seventh layers are in ranges of 0.122d1 to 3.052d1, 0.267d2 to 0.370d2, 0.427d3 to 0.610d3, 0.760d4 to 0.924d4, 0.305d5 to 0.378d5, 0.575d6 to 0.718d6, and 1.160d7 to 1.342d7, correspondingly, wherein di=λ/(4×ni), (i=1, 2, . . . 7), ni is a refractive index of the i-th layer, and λ is a reference wavelength of incident light entered into the antireflection film.
Abstract:
A light guide is a quarter of cylinder in shape and includes a cylindrical emitting surface, an incident surface adjacent to and facing away from the cylindrical emitting surface, and a connecting surface connecting the cylindrical emitting surface and incident surface. The light guide defines five a number of grooves in the incident surface. Each groove is bounded by two surfaces. The inclined angle of the two surface is designed to satisfy a set of conditions to improve light uniformity of the cylindrical emitting surface.
Abstract:
A vehicle wheel includes a wheel body and a plurality of rim blades. The plurality of rim blades is coupled to at least one side surface of the wheel body. Each of the rim blades is provided with at least one airflow guide section and at least one airflow-assisting section. The airflow guide section and the airflow-assisting section are arranged in the form of front and rear series on the rim blade. When the vehicle wheel is coupled with a tire, the airflow guide section is located at the side of the rim blade facing a forwarding direction of rotation of the wheel and the airflow-assisting section is located at the side of the rim blade opposite to the forwarding rotation of the wheels. As such, airflow is increased, wind resistance is reduced, and noise is reduced.
