Abstract
The invention discloses a surface mount type LED virtual display screen RGB lamp bead structure, which relates to the field of surface mount type RGB lamp beads and solves the problem that fluorescent powder on a reflecting cup is exposed to the outside illumination environment for a long time when the existing surface mount type LED virtual display screen RGB lamp bead structure is used, and the aging and falling phenomena are easy to occur.
Description
Technical Field
The invention relates to the technical field of surface mount type RGB lamp beads, in particular to a surface mount type RGB lamp bead structure of an LED virtual display screen.
Background
The English language of the LED is (light emitting diode), and the LED lamp bead is the English abbreviation of the LED which is called LED for short, which is a popular name. The working principle is as follows: the terminal voltage of the PN junction forms a certain potential barrier, when a forward bias voltage is applied, the potential barrier is lowered, and most carriers in the P region and the N region diffuse to each other. Since the mobility of electrons is much higher than that of holes, a large number of electrons diffuse into the P region to form injection of minority carriers in the P region, and the electrons are recombined with holes on the valence band, and energy obtained during recombination is released in the form of light energy. The Virtual Vision (VV) is characterized by generating a high-quality picture in a small volume. To meet the requirements of producing high resolution images at very small dimensions with a minimum visual resolution angle limit (about 60') for the human eye, a correspondingly precise optical system must be associated therewith. In addition, virtual displays differ from ordinary displays primarily in that they can provide much higher resolutions, most displays having full color resolution of only 80-100 lines/inch, while virtual displays can provide color resolution of up to 1000 lines/inch or more.
The white light LED and the RGB LED both have the same major attributes, and it is desired to achieve the effect of white light, but one is directly presented as white light, and the other is formed by mixing red, green and blue lights. The RGB lamp is imaged by the common intersection of three primary colors, in addition, a blue LED is matched with yellow fluorescent powder, and an ultraviolet LED is matched with the RGB fluorescent powder, and the two lamps have imaging principles integrally. Some LED backlight panels have a clear and vivid color, even have a high-definition television, and in this case, it is the feature of RGB that the placard red is red, green is green, and blue is blue, and the color mixing of light has more diversified characteristics.
Fluorescent powder can be coated on the surface of current RGB lamp pearl reflection of light cup and come reinforcing reflection of light effect, red green blue three-colour light that launches out through light source department fuses each other through reflection of light cup during the use, spill through the lamp shade, reach the effect that demonstrates different colours, because the close time of the virtual display screen of LED will be far longer than opening time, simultaneously in order to guarantee the printing opacity effect, the lamp shade can have better light transmissivity, external light also can enter into inside through the lamp shade more easily this moment and shine the fluorescent powder, make the fluorescent powder on the current reflection of light cup expose under external light for a long time, produce easily and drop, reflection of light effect when influencing the use, reduce the intensity of RGB light, influence the display effect of virtual display screen, for this reason, we propose a SMD virtual display screen lamp pearl structure of LED.
