Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to the structural improvement of light-emitting diodes, especially a kind of fluorescent cover with LED chips, which can produce high brightness and uniform color. White light emitting diode. [Previous technology] One-click, traditionally, to make white LED, three red, blue and green light-emitting chips with different colors are packaged together. At the same time, solid-state bonding is more complicated, and the driving voltage required by different chips. It is also different, so when setting the punch circuit, add different driving current to each LED chip to adjust the brightness and color, which is its disadvantage. Newer manufacturing methods, such as China ’s Announcement No. 5 8 3 7 7 7 “Method for Making White Light-Emitting Diodes” invention patent case, is based on flip-chip technology (IP — chip) to GaN gallium nitride light-emitting diodes. After the particles are combined with the substrate, a stencil with holes is used, and the colloid containing the fluorescent powder is printed and coated, so that the colloid containing the fluorescent powder is uniformly coated around and around the surface of the light-emitting polar crystal grains. Baking hardens the colloid containing fluorescent powder, and then molds the transparent colloid through the die-casting method, and then cuts into a surface-adhesive white light-emitting diode by a cutting method. One is the use of a single blue LED die, coated with two layers of fluorescent colloid on the surface of the die and baked to harden, and the blue colloid produced by the light-emitting die excites the glorious colloid to produce light with different wavelengths. It is then mixed with the color of the light emitted by the original light-emitting crystal grains to produce white light. The specific method can be blue light LE ^ crystal grains, plus γ a G yellow phosphor, or ultraviolet LED crystal grains, red, yellow, Green tri-color phosphors to achieve.

LED die polar body. New content] or L Ε on the net, which is lacking in color and light, and there are two basic methods: ί Production method 'It's all coated with glue. Therefore: !! The body is coated on the crystal ^, which is in quantitative control. The phenomenon that the color light is bluish or yellowish leads to the disadvantage of uneven light. The disadvantages of the above-mentioned conventional white LED production are uneven coating, resulting in uneven white light brightness, and other unevenness. The author of this case is aimed at the above research and design, and has been improved through various experiments. The main purpose is to design a kind of white light with uniform color and light that can be made by using the fluorescent cover body. In order to achieve the aforementioned purpose, the structure of a white light-emitting diode designed in this creation is mainly modified with different components. Compared with fluorescent powder, it is added into a temperature-resistant engineering plastic, such as PC (polycarbonate resin), and is injection-molded into a-fluorescent cover (set), and then the fluorescent cover is glued on top of the light-emitting LED die. Bake and combine them, and then implant the implanted pellets to make LEDs, or package white light SMD light-emitting poles or LED displays in a mold-binding method. According to different LED production methods, relatively different crystal grains, and different light emitting angles Different fluorescent powders, suitable fluorescent covers are designed to achieve a uniform thickness and a uniformly distributed fluorescent powder. The white light-emitting diodes with high brightness and uniform color are obtained after excitation.
