【 Weak current College 】 LED in the application of optical mouse 】

Generally our common optical mouse usually refers to the use of opto-components, depending on the mobile surface image logic to generate information on mouse move.
Optical mouse works: in electro-optical mouse inside a light emitting diode that emits light emitting diode lighting, illuminating the surface at the bottom of the electro-optical mouse (this is why the mouse causes the bottom will shine). And then the bottom surface of the optical mouse reflected back to the light, as part of a group of optical lens, transfer to a light-sensing device (micro imager) imaging.
Then, when the mouse moves, photoelectric its mobile rail sites will be recorded as a set of coherent image of high speed photography. Finally use the internal optical mouse a dedicated image analysis chip (DSP, i.e. digital microprocessor) on mobile rail sites on the uptake of a series of image analysis and processing, through these image features point location changes for analysis, to determine the direction of the movement of the mouse and move distance to complete cursor positioning.
Optical mouse usually consists of the following: optical sensors, optical lenses, light-emitting diode, interface microprocessors, touch keys, scroll wheel, wiring, PS/2 or USB interface, shell, etc. But our priorities to understanding of light-emitting diode (LED) in the application of optical mouse.
We know that the optical mouse in use during the bottom fades to red light will be issued. This is the light-emitting diode in the mouse, it plays in the mouse's role? luminescent diode issue highlighted (this is mainly to get enough illumination) light, part of optics at the bottom of the mouse (that is, the Prism) to light at the bottom of the mouse; the other part directly to the front of the optical sensors. Popular standpoint, it is the role of light emitting diodes are the light generated mouse work sent in the required light source.

But why common optical mouse use LED is red?
Why choose red? actually causes more simple, because red light source LED technology is more mature and cost calculation is cheaper. This makes the Red led of the longest service life. And optical engine for Imaging is monochrome, no matter what the color of the light source has no effect. So in this case, with the exception of a few manufacturers to create a selling point, most vendors will choose red products, such as the number of photoelectric mouse also with blue LED, and the network's different but essentially the same.
In addition, the combination of in-line LED and SMDLED can also be used to decorate the mouse so that it issued seven color colorful light, more attractive eye. More in line with the fashion of a family of aesthetic needs. Global annual production of electro-optical mouse, hundreds of millions of dollars to each mouse consumption 1 star ~ 7 bright LED, the economic and effective support to the part of the led industry of shipments.
Looking to the future, even if the laser mouse is a popular trend, but still can not be separated from the auxiliary light emitting LED. Doubted this, based on the current status of optical mouse universal, LED the application of the mouse still occupy according to absolute dominant position is not shake.
