Problems solved by technology

In the prior art, the phosphor powder coating method is to mix the phosphor powder with glue or slurry and then spray it on the light-transmitting sheet. The phosphor powder is unevenly sprayed, the spray thickness cannot be adjusted, and the spray thickness is inconsistent, which leads to the light source. Poor consistency, low product qualification rate, poor lighting effect

Embodiment Construction

[0026] Specifically, such as figure 1 and figure 2 As shown, the pressing part 300 includes a supporting column 330, a lower base plate 320 located at the lower end of the pressing part 300 and a fixing ring 310 located at the upper end of the pressing part 300, the lower base plate 320 and the fixing ring 310 are arranged at intervals in parallel to The container cylinder 200 is reliably pressed into the frame assembly to prevent the dispersion liquid in the container cylinder 200 from leaking out. The fixed ring 310 and the lower base plate 320 are fixedly connected by the support column 330, and the container cylinder 200 is arranged on the bottom of the lower base plate 320. Above, the pressing member 300 also includes a pressing cover 340 that is connected to the fixing ring 310 and can compress the container barrel 200. Specifically, the pressing cover 340 is screwed to the fixing ring 310, so as to facilitate Fixing and taking out of the container cartridge 200. In ...

Abstract

The invention is suitable for the technical field of fluorescent powder coating, and discloses a fluorescent powder coating device and a coating method utilizing the same. The fluorescent powder coating device is used for coating fluorescent powder on a plane light-source transmission sheet, and comprises a container cylinder and a compression part which can hold down and seal the transmission sheet onto the opening port of the container cylinder and can be arranged inside an ultrasonic washing machine, wherein fluorescent powder and dispersion liquid are installed inside the container cylinder. The fluorescent powder coating method comprises the following steps that: (1) the container cylinder is held down onto the transmission sheet through the compression part; (2) the fluorescent powder and the dispersion liquid are added into the container cylinder; (3) the compression part, the container cylinder and the transmission sheet are collectively arranged inside the ultrasonic washing machine so as to disperse the fluorescent powder; and (4) the dispersion liquid is evaporated and dried. Due to the adoption of the fluorescent powder coating device and the coating method utilizing the same, the fluorescent powder can be uniformly coated on the transmission sheet, the coating thickness is adjustable, and the coating thickness is high.

Description

technical field [0001] The invention belongs to the technical field of fluorescent powder coating, and in particular relates to a fluorescent powder coating device used on a plane light source transparent sheet and a coating method using the coating device. Background technique [0002] In daily life, various types of light sources can be seen everywhere, such as fluorescent lamps, car lights, traffic lights, etc. Light sources can be roughly divided into point light sources (such as LEDs), linear light sources (such as fluorescent tubes) and surface light sources according to their shape and size. The surface light source can emit light through an array of point light sources or line light sources and add some optical elements for homogenization, or form a surface light source in the form of a light guide plate. In the application of surface light source, it is mainly used in lighting, liquid crystal display (LCD) backlight, display light box and so on. In addition to in...
