Problems solved by technology

[0008] However, the above process has the following disadvantages: 1. The fluorescent powder mixture will be affected by the shape of the cup mouth of the bracket, resulting in a yellow or blue circle phenomenon, which affects the quality of light output; 2. The way of dispensing is to use gravity and other mechanical e

Abstract

The invention discloses an LED fluorescent lampshade which comprises a lamp holder interconnecting piece and an LED lamp wick accommodating chamber. An LED lamp wick insertion hole portion of the LED lamp wick accommodating chamber is fixed to the lamp holder interconnecting piece. The outer wall of the LED lamp wick accommodating chamber is provided with heat radiation through holes. The manufacturing method of the LED fluorescent lampshade comprises the following steps: (1) lampshade shape design, (2) material mixing, (3) granulation, (4) molding, and (5) machine tooling. With the LED fluorescent lampshade and the manufacturing method thereof provided by the invention, the traditional practice of mixing fluorescent powder and silica gel/resin and covering an LED chip with the mixture is changed, and light is emitted directly through the fluorescent lampshade, which is beneficial to the heat radiation of an LED device and the increase of the service life of the LED device. At the same time, the use of the fluorescent lampshade eliminates the situation that the transition efficiency of the fluorescent powder is reduced due to the heat generated by the LED chip at work, and makes the emitted light stable and uniform.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to an LED fluorescent lampshade with light conversion effect used in conjunction with an LED light source and a manufacturing method thereof. Background technique [0002] In recent years, whether it is inorganic or organic light-emitting devices (LED / OLED), white LED devices and their applications in lighting-related fields have received great attention from both academic and industrial circles. There are two main ways for white LEDs to produce white light: the first is to combine red, green and blue LED chips to produce white light; the second is to use LEDs to excite photo-induced conversion phosphors to form white light. A more mature method is to use blue LED chips with yellow phosphors (such as YAG: Ce3+, etc.) to achieve white light emission. [0003] For photoconverted white LEDs, the structure and characteristics of phosphor coatings have a crucial impact on the performance of wh...
