The LED controller for portable equipment can achieve the flexible linear programmable control of multiple paths of LED, can flexibly select the programmable control according to different display needs, and has the advantages of wide application range and easy control.
Description
Technical field
The utility model relates to the led controller that a kind of mobile phone, portable multimedia broadcasting are put portable sets such as equipment, GPS.
Background technology
Along with the continuous development of science and technology, the application of portable set is more and more wider, as mobile phone, portable media player MP4, GPS or the like, greatly facilitates people's life.Often adopt LED as backlight in these portable sets, often use the LED lamp simultaneously on these equipment, also use the compact LED array on some portable set as display screen as decorating or various display effects being provided.
The principle of luminosity of LED is all different with the principle of luminosity of incandescent lamp and gaseous discharge lamp, and the energy conversion efficiency of light source is very high, do not have interference emission, energy-conserving and environment-protective simultaneously again.Use LED under the normal condition, its nominal life 100,000 hours has reduced replacing frequency and other maintenance works.Because the spectral region of typical LED is all narrow photochromic pure, has full spectrum unlike incandescent lamp, therefore, LED can arbitrarily carry out diversified matched combined, is specially adapted to aspects such as decoration.Because outside epoxy resin that adopt of LED are protected more, so sealing property and shock proof performance are all fine, are not easy to damage.LED also has other advantages short etc. as: low in calories, miniaturization, response time, and these all make led light source have very big advantage, for being applied to have created advantage in the actual production life.
But be applied to led controller on the portable set at present and can only simply control one the road or the unlatching of several paths of LEDs or close or control light and shade, displaying contents is simple.A plurality of if desired LED constitute certain pattern or often special circuit need be set at different types by the certain effect of open-interval variation formation on portable set, can't realize programming Control, its scope of application is narrow, be unfavorable for the commercialization popularization, function is also powerful inadequately simultaneously, can't satisfy the needs of portable set display unit development.
The utility model content
The utility model provides a kind of portable set led controller, can realize the control able to programme of the flexible line style of LED multi-path.
For solving the problems of the technologies described above, the utility model provides a kind of portable set led controller, comprises bus interface, is used for carrying out transfer of data with the processor of portable set; Decoding circuit is connected with bus interface, is used for the data that transmission comes to bus interface and decodes; At least the two-way drive circuit is connected with decoding circuit respectively, drives the LED pipe of control separately according to the signal of decoding circuit.
Portable set led controller described in the utility model can be realized the control able to programme of the flexible line style of LED multi-path, needs programming Control flexibly at different demonstration, has applied widelyly, controls advantage easily.Simultaneously, can improve the function of portable set so that the LED of portable set demonstrates specific pattern or display effect by certain control.

Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, the utility model comprises bus interface, is used for carrying out transfer of data with the processor of portable set; Decoding circuit is connected with bus interface, is used for the data that transmission comes to bus interface and decodes; At least the two-way drive circuit is connected with decoding circuit respectively, drives the LED pipe of control separately according to the signal of decoding circuit.Realize control able to programme by bus interface realization chip with being connected of CPU, realize the Linear Control of LED multi-path by decoding and driver circuit.Can carry out programming Control to a plurality of LED pipes easily by the utility model.The number of drive circuit wherein can be the 4-10000 road.
As shown in Figure 2, in a kind of implementation of the present utility model, realize high-speed serial bus and the chip transmission of data that utilizes computer connected in series of chip and CPU by serial bus interface.Utilize string and conversion line that serial signal is converted to multi-path parallel signal.Utilize the multi-channel digital and analogue change-over circuit that the parallel data on every road is converted to the analog-driven level.Utilize drive circuit that the analog-driven level conversion is exported driving LED for analog current.
The utility model is not limited to execution mode discussed above.More than the description of embodiment is intended in order to describe and illustrate the technical scheme that the utility model relates to.Based on the conspicuous conversion of the utility model enlightenment or substitute and also should be considered to fall into protection range of the present utility model.Above embodiment is used for disclosing best implementation method of the present utility model, so that those of ordinary skill in the art can use numerous embodiments of the present utility model and multiple alternative reaches the purpose of this utility model.
