Embodiment
A kind of light display apparatus that utilizes audio frequency input control light display effect of the present invention is seen Fig. 1.This light display apparatus comprises audio treatment part 1, reference level adjustment part 2, light display mode adjusting portion 3, light control part 4 and light display part 5.
Audio treatment part 1 comprises the acoustic processing chip 11 and the first analog-to-digital conversion circuit 12, and audio treatment part 1 is converted into the audio signal of input digital signal and sends light control part 4 to.
Reference level adjustment part 2 comprises master chip 21, integrating circuit 22 and the second analog-to-digital conversion circuit 23.The square wave of the master chip of display or television set (Scalar) 21 outputs is converted into DC level through integrating circuit 22, is converted into digital level and sends light control part 4 to as reference level through the second analog-to-digital conversion circuit (ADC).
Light control part 4 comprises digital comparator (MCU) 41, and digital comparator 41 compares processing with digital signal and reference level, and the light of light display part 5 is shown quantity and controls in proper order.
Light display mode adjusting portion 3 is connected with light control part 4, passes through the communication of IIC agreement between Scalar and the MCU.
Light display part 5 comprises one group of LED lamp and light-passing board, on light-passing board, be provided with reasonable organization can printing opacity white portion and black part that can not printing opacity, one group of LED lamp is installed in the light-passing board rear side.
Fig. 2 is the comparison diagram of reference level and audio signal among the present invention.Wherein A is a reference level, and B is an audio signal, when audio signal level during, lamp luminescence greater than reference level, on the contrary then not luminous.Reference level is a reference voltage, can regulate in menu, and reference level is low more, and then lower audio signal also can make light luminous.
The present invention can select different display effects in menu, the display mode of LED can have following several:
1, GAME pattern: according to the size of audio frequency, the LED lamp from sequence of light be from the centre to both sides, see Fig. 3.
2, MOVIE pattern: according to the size of audio frequency, the LED lamp is in the middle of two side direction from sequence of light.
3, MUSIC pattern: according to the size of audio frequency, the LED lamp is to both sides from the centre from sequence of light.
4, OFF pattern: LED is middle successively luminous successively from two side direction, then Close All.
The present invention can control the demonstration quantity of LED lamp according to the size of audio frequency:
The size of detection reference level, the level size of audio frequency.With each level size conversion is numerical value.
Suppose reference level a, the level b of audio frequency.
When supposing 0＜b-a＜d, the LED lamp is luminous.
1, when b-a＜=0, promptly the level of audio frequency is less than reference level, and the LED lamp is all not luminous.
2, during b-a＞=d, the LED lamp is all luminous
3, suppose the X that adds up to of LED etc.D is divided into the n five equilibrium.
As 0＜b-a＜=n/d, the luminous quantity of Led lamp is X/n.
As n/d＜b-a＜=2n/d, the luminous quantity of Led lamp is 2X/n.
And the like
The present invention is provided with the luminous loop of some in display or TV, and according to the size of audio frequency input, and the sequence of light in each luminous loop realizes the display effect of light-emitting device.
