An electrodeless fluorescent lamp with improved fluorescent powder configuration and its manufacturing method
[Abstract] An electrodeless fluorescent reflector lamp comprises a lampshade device with a threaded lamp base to receive line power, and a lamp housing mounted on the lampshade device. The ballast circuit is placed in the lampshade device and effectively used to convert the line power into an RF signal to excite the filling material inside the lamp housing to a discharge state, resulting in visible light. The lamp housing has an upper curved flat portion and a lower conical portion that partially extends into the lampshade. Reflective coating is applied to the lower cone part of the lamp housing. The first thickness of the fluorescent powder material located in the lower cone portion is generally thicker than the second thickness applied to the upper curved surface portion of the lamp housing, thereby improving the light output characteristics of the reflector lamp.
Display device and manufacturing method of display device
[Abstract] A straight display device (100A) comprises: at least one display panel (10) having a display area (10A) and a border area (10F) arranged outside the display area, with a boundary (B1) extending along a first direction (D1) between the display area (10A) and the border area (10F); And at least one translucent cover (20) configured on the observer side of at least one display panel (10). At least one translucent cover (20) has a lens portion (22) arranged to cross the boundary (B1) and refract a portion of the light emitted from the display area (10A) towards the frame area (10F). The exit surface (22A) of the lens portion (22) is curved, and at least a portion of the exit surface (22A) is subjected to anti reflection treatment. According to this technology, it is possible to provide a straight display device that is difficult to see the border area of the display panel and can suppress the reflection on the lens part.
Vehicle lighting fixtures and their manufacturing methods
[Abstract] This technology provides a vehicle lighting fixture and its manufacturing method that can improve production efficiency even when a lampshade covering the bulb from the light distribution mirror side is installed on the housing for shading. A housing (16) with a reflective surface (15), a light bulb (18) mounted on the housing (16), a light distribution mirror (20) covering the reflective surface (15), a lampshade (41) covering the light bulb (18) from the light distribution mirror (20) side to block light is mounted on the housing (16), an opening (48) is provided on the side of the lampshade (41), and aluminum vapor deposition layers (39, 53) are formed on the surfaces of the reflective surface (15) and lampshade (41).
Diffuse reflection structure and its manufacturing method, as well as display devices using the structure
[Abstract] One of the objectives of this technology is to obtain a simple and stable diffuse reflection structure that exhibits a desired reflection directionality. The manufacturing method of a diffuse reflection structure includes: depositing a photosensitive material 2 on a base layer; Using a half tone photomask 3 to shield the photosensitive material 2, the half tone photomask 3 has at least one of a transmission area 31 and a light area 32, and has a half transmission area 33; By exposing the photosensitive material to light through the photomask 3 and developing the material, unevenness 21, 22 is formed on one of the surfaces of the photosensitive material layer. The unevenness corresponds to a peak portion and a half portion, where the peak portion corresponds to one of the regions 31, 32 and the half portion corresponds to the semi transmissive region; And deposit an optical reflective material 4 on the uneven surface formed. In order to transmit the incident light with a grayscale, the photomask 3 includes a stripe arrangement portion in one or both of the transmission area 31 and the light area 32, and/or in the semi transmission area 33, which has the ability to transmit the incident light with a relatively high first transmittance
