  • Patent number: 10014435
    Abstract: A metallic reflector manufacturing method for an LED package. The method includes preparing a metal plate, and processing a stamping reflector that includes a lower body and an upper body that is extended from an upper side of the lower body and is integrally formed with the lower body. A reflection surface that is slanted by a predetermined angle is formed at a central portion of the upper body and the lower body to reflect the light of the LED chip to the outside. A fixation portion is formed to fix the lower body on a substrate that the LED chip is mounted on. The method further includes sequentially plating Ni and Ag on the reflection surface or the stamping reflector surface. The stamping processing includes a piercing step, a drawing step, a first noting step, a half etching step that forms the fixation portion, and a second notching step.

  • Patent number: 10006597
    Abstract: Disclosed is a bubble lamp for quasi bubble flow. A buffer made of a transparent material having an excellent heat conduction effect and impact moderating performance is configured on the top of the bulb configured on the main body of the bubble lamp or on the bottom of the glass tube configured on the upper cover, and the casing made of a transparent and no-easily-broken material is put around the glass tube, thereby abutting the glass tube against the top of the bulb across the buffer when the upper cover is covered on and coupled to the main body, allowing both the glass-made bulb and glass tube to be buffered by the butter and thus to block or decrease an impact when a contact force is too large upon assembly, and preventing the bulb or glass tube from being broken.

  • Patent number: 9908462
    Abstract: An illumination device for the rear license plate of a motor vehicle includes a carrier wall bearing the license plate, to which a wall area forming a projection is connected, which projects rearwards above the license plate with an approximately horizontal surface. An aperture is located on the projection side and a switchable light source is located thereabove. The aperture is covered by a transparent lens, with an overlapping edge of the lens fastened from below to a contact edge surrounding the aperture. Light radiated by the light source through the lens is radiated through the surface inside the overlapping edge to the license plate. The lens has a light-guiding and/or light-deflecting element which is arranged such that light is also passed to at least a partial area of the rear overlapping edge of the lens and radiated at a predetermined luminance, to the license plate.
