Abstract
The invention discloses a manufacturing method of a light emitting diode (LED) lamp panel for converting blue light into white light. The method comprises the following steps of: mixing transparent ink and fluorescent powder to form a mixture; printing the mixture onto a fluorescent diffusion plate by using a screen printing machine, and curing the mixture by the irradiation of an ultraviolet (UV) lamp to obtain an LED fluorescent diffusion plate; and jointing the LED fluorescent diffusion plate and an LED blue light lamp sheet to obtain the LED lamp panel. By the method, the production links can be reduced, and the production cost can be reduced; by the method, volume production is performed by using self-owned technologies without depending on foreign encapsulation patents; and self-owned equipment can be used for production so as to reduce the cost.
Description
Technical field
The present invention relates to a kind of production method of LED lamp plate.
