Description of drawings
Fig. 1 is the module position schematic diagram of the utility model one embodiment;
Fig. 2 is the Assembled lamp structure chart of the utility model one embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model technology is described in detail.
Referring to Fig. 1, Fig. 1 is the module position schematic diagram of the utility model one embodiment, and the utility model Assembled lamp mainly is made up of single-chip microcomputer among Fig. 12 and LED lamp 4.Among Fig. 1, printed substrate (PCB) 1 is provided with single-chip microcomputer 2, even light spare 3 and light emitting diode (LED) lamp 4, and the quantity of LED lamp 4 can be for one or more, and each LED lamp is linked in sequence.Wherein, single-chip microcomputer 2 and LED lamp 4 link to each other by PCB1, and even light spare 3 is used to improve the uniformity of light efficiency.
When practical application, the light efficiency of Assembled lamp shown in Figure 1 is: when secretly brightening, there is laddering difference in the brightness of each the LED lamp that is linked in sequence, and increases gradually, up to the LED lamp when the brightest by bright deepening; By bright deepening the time, there is laddering difference in the brightness of each the LED lamp that is linked in sequence, and weakens gradually, up to the LED lamp when the darkest by secretly brightening.
Above-mentioned light efficiency has more flowability, even very perfect mobile light efficiency is also arranged when watching on hand.If wish to realize this light efficiency, then need to carry out setting as shown in Figure 2.
Referring to Fig. 2, Fig. 2 is the Assembled lamp structure chart of the utility model one embodiment.Among Fig. 2, selected single-chip microcomputer is the AT89C2051 (in fact, can also select the single-chip microcomputer of other model for use, carry out the light efficiency setting and can show smoothly to guarantee required light efficiency as long as can use this single-chip microcomputer) of MCS51 series.The output port P10 to P17 of single chip computer AT 89C2051 is connected with LED lamp L1 to L8 respectively.
When concrete the application, single chip computer AT 89C2051 inside is provided with the light efficiency performance element.At control LED lamp when secretly brightening, described light efficiency performance element to output port P10 to P17 respectively output duty cycle have the PWM waveform signal of laddering difference, and the dutycycle of each PWM waveform signal of output all increases gradually, and the PWM waveform signal dutycycle that just will export to this LED lamp up to the LED lamp when the brightest weakens.When controlling the LED lamp by bright deepening, described light efficiency performance element to output port P10 to P17 respectively output duty cycle have the PWM waveform signal of laddering difference, and the dutycycle of each PWM waveform signal of output all weakens gradually, and the PWM waveform signal dutycycle that just will export to this LED lamp up to the LED lamp when the darkest increases.
Because the increase of PWM waveform signal dutycycle/weaken the increase that can cause output current/weaken, therefore the brightness of output current each LED lamp of flowing through will correspondingly be strengthened/weakened, and finally make when secretly brightening, there is laddering difference in the brightness of each the LED lamp that is linked in sequence, and increase gradually, up to the LED lamp when the brightest by bright deepening; By bright deepening the time, there is laddering difference in the brightness of each the LED lamp that is linked in sequence, and weakens gradually, up to the LED lamp when the darkest by secretly brightening.
In actual applications, can also be at the inner instruction input block that links to each other with the light efficiency performance element that is provided with of single chip computer AT 89C2051.Described instruction input block links to each other with the input pin of single chip computer AT 89C2051, can instruct by the different light efficiencies that this input pin receives from the user, and send different light efficiency fill order (this order can realize by level or incident) to the light efficiency performance element according to different light efficiency instructions; The light efficiency performance element is then according to the light efficiency fill order from the instruction input block, carries out corresponding light efficiency output (as: aforesaid running lamp light efficiency output, and the output of scroll bar light efficiency etc.).
Certainly, can realize, need in the light efficiency performance element, set in advance different light efficiency output such as running lamp, scroll bar in order to guarantee different light efficiency output.And principle and the aforesaid running lamp light efficiency output principle of light efficiencies such as scroll bar output are basic identical, just the LED lamp during specific implementation bright/time sequencing difference secretly.In addition, also can not use described PWM waveform signal, and use the waveform signal of other type, as long as can be to LED lamp output variable current; In like manner, also can not use the LED lamp, but use other lamp.
Above-mentioned Assembled lamp can be arranged in the electronic equipments such as mobile phone, desktop computer, notebook computer, PDA, handheld game machine.
By the above as seen, Assembled lamp of the present utility model and comprise the electronic equipment of this Assembled lamp, the waveform signal that can have laddering difference to each LED lamp output duty cycle, and the dutycycle of each waveform signal of output all increases gradually/weakens, and weakens/increases in the brightest/waveform signal dutycycle that just will export to this LED lamp when the darkest up to the LED lamp; This finally make by secretly/during bright brightening/dark, there is laddering difference in the brightness of each the LED lamp that is linked in sequence, and increases gradually/weaken, up to the LED lamp the brightest/when the darkest by bright/dark deepening/bright, finally effectively improved mobile light efficiency.
