Abstract

The utility model discloses a frequency spectrum music lamp, which is invented to resolve the problems of lack of imaging maneuverability of light sources and the like in the prior art. The frequency spectrum music lamp is characterized by comprising a power source module, an LED lamp group, an audio frequency input sensing module and an FFT frequency spectrum analysis module, wherein the LED lamp group is formed by combining a circuit board and more than one LED light emitting body arranged orderly and fixed on the circuit board in a same direction. When the power source module is on, a sound source enters the audio frequency input sensing module, and the FFT frequency spectrum analysis module analyses amplitude of all frequencies and drives the LED lamp group to emit lights of different frequencies via the amplitude.

Description

The frequency spectrum music lamp

Technical field

The utility model relates to light fixture, relates in particular to a kind of frequency spectrum music lamp.

Background technology

The various decorating lighting lamps of known existing open air, often adopt light fixture of all kinds to make the light source of single look, sometimes for reaching color effect, in the zone with the lamp assembled arrangement of multiple colour together, produce a kind of color illumination system by the combination of light sources of separating, if a lamp dimmer is installed before the electric main of lamp body, the lamp group also can demonstrate various change light effects by the track that sets, yet, shown lighting effects and the change light effect that utilizes lamp dimmer to produce all are in advance with the good track of programming, there is certain limitation, more can not change lighting effects because of effects such as extraneous sound sources, lack mobility, be difficult to satisfy the composite demand that present people produce light source.

The utility model content

Main purpose of the present utility model is to provide a kind of frequency spectrum music lamp, overcomes the limitation of light source imaging in the existing light fixture, promotes the composite demand that people produce light source.

For reaching above-mentioned purpose and effect, the utility model provides a kind of frequency spectrum music lamp, comprising:

LED lamp group is arranged in order by circuit board and more than one and the LED illuminator that is fixed on the circuit board according to equidirectional combines;

Audio frequency input sensing module is used for receiving external voice and the amplitude of voice signal is amplified back output;

FFT (Fast Fourier Transformation) spectrum analysis module is used for receiving the amplifying signal of audio frequency input sensing module output, and outputs to LED lamp group after calculating amplitude on each frequency;

Power module is used for providing electric energy for audio frequency input sensing module and FFT spectrum analysis module.

Wherein, described LED lamp group is 1-63.

Wherein, described LED illuminator is any one or arbitrarily combination in white, red, yellow, the blue four look LED illuminators.

The beneficial effect of the utility model frequency spectrum music lamp is: by audio frequency input sensing module, the FFT spectrum analysis module combines sound size, the rhythm speed of sound source with LED lamp group, the conversion that LED lamp group is also glittered simultaneously and jumped at the change time point of sound source, make sound source and luminous point one integrated mass, it is the innervation that is rich in again attractive in appearance, add LED and have pollution-free, characteristics such as light efficiency is high, little power consumption, vibration resistance shock resistance, the utility model frequency spectrum music lamp is more had practical value.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Specific embodiment

As shown in Figure 1, can find out clearly that the utility model mainly comprises: power module, audio frequency input sensing module, FFT spectrum analysis module, and LED lamp group, described power module and audio frequency input sensing module, FFT spectrum analysis module, lamp group take turns doing electric connection.During use, LED lamp group is fixed on the fixed head usually.

Its operation principle is: when power module keeps energising, sound source enters audio frequency input sensing module, audio frequency input sensing module amplifies signal amplitude exports to the FFT spectrum analysis module, by the FFT spectrum analysis module amplitude analysis on each frequency is come out again, promote to demonstrate the illumination effect that glitters and jump on the LED lamp group by amplitude.

Wherein, above-mentioned audio frequency input sensing module can comprise external inductor, as various microphones, receiver etc. all can, as long as sound input luminous point is arranged is convertible effect to reach.

Above-mentioned LED illuminator can in white, red, yellow, the blue four primary-color LED illuminators any one, can control the luminous of wherein arbitrary LED illuminator by control module.

The quantity of above-mentioned LED lamp group can be selected as required, as being 1-63.

Above-mentioned lamp group is made up of multiple LED illuminator, and luminous point quantity is not limit and can be provided with as required.

This shows that the utility model is easy to operate flexibly and cost is low, is applicable to places such as hotel, restaurant, bar, public place of entertainment, open air, vehicle-mounted, the car that also can be used for family's video display wall, automobile is hung, on the railing of park, not only attractive in appearance but also safety, and power consumption is low.

More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
