Utility model content

Technical problem to be solved in the utility model is to provide a kind of integral intelligent LED flat lamp, and this integral intelligent LED flat lamp structure is small and exquisite, feature richness, is a kind of intelligent light fixture.

The technical solution of utility model is as follows:

An integral intelligent LED flat lamp, comprises substrate and is arranged on three-color LED light array on substrate, DSP, light intensity sensor, light-adjusting module and for receiving the control interface of external command; Light intensity sensor is all connected with DSP with control interface;

Three PWM output ports of DSP connect respectively the public control port of R, G, B of three-color LED light array; The 4th the PWM output port of DSP is connected with the control end of light-adjusting module; The output of light-adjusting module connects the feeder ear of three-color LED light array;

Described DSP adopts DSP2407 chip.

Beneficial effect:

Integral intelligent LED flat lamp of the present utility model, adopts integral structure, and all devices are all integrated on substrate, and structure is small and exquisite; Possess the function with an automatic light meter according to outside brightness, can show multiple color, feature richness, is a kind of intelligent light fixture, is especially suitable as side lamp and the taillight of automobile.

Accompanying drawing explanation

Fig. 1 is the overall electric theory diagram of integral intelligent LED flat lamp.

The specific embodiment

Below with reference to the drawings and specific embodiments, the utility model is described in further details:

Embodiment 1:

As shown in Figure 1, a kind of integral intelligent LED flat lamp, comprises substrate and is arranged on three-color LED light array on substrate, DSP, light intensity sensor, light-adjusting module and for receiving the control interface of external command; Light intensity sensor is all connected with DSP with control interface;

Three PWM output ports of DSP connect respectively the public control port of R, G, B of three-color LED light array; The 4th the PWM output port of DSP is connected with the control end of light-adjusting module; The output of light-adjusting module connects the feeder ear of three-color LED light array;

The R of three-color LED light array, G, the public control port of B, refer to that the R control end of all tri coloured lanterns in three-color LED light array is shorted together formation common port R; The G control end of all tri coloured lanterns is shorted together and forms common port G; The B control end of all tri coloured lanterns is shorted together and forms common port B.

Described DSP adopts DSP2407 chip.

DSP2407 has 16 road PWM output channels, gets its 4 passages.

Integral intelligent LED flat lamp adopts integral type modular organization, comprises three-color LED light array and relevant control module (DSP) and the attached device of sensor.

When as automobile tail light, when external environment condition is brighter, control LED lamp luminous stronger, make follow-up vehicle can identify the state of automobile, the security that therefore improves automobile.In addition, the light kind of automobile has yellow, redness etc., and this integral intelligent LED flat lamp can produce different colours, and therefore, a LED flat lamp can replace a plurality of existing lamps.

Control interface is for receiving the signal of other main control modules, and such as 00 expression red light is opened, 01 expression amber light is opened, and 11 represent to turn off the light, and control interface is ripe interface module.

Claims (1)

1. an integral intelligent LED flat lamp, is characterized in that, comprises substrate and is arranged on three-color LED light array on substrate, DSP, light intensity sensor, light-adjusting module and for receiving the control interface of external command; Light intensity sensor is all connected with DSP with control interface;

Three PWM output ports of DSP connect respectively the public control port of R, G, B of three-color LED light array; The 4th the PWM output port of DSP is connected with the control end of light-adjusting module; The output of light-adjusting module connects the feeder ear of three-color LED light array;

Described DSP adopts DSP2407 chip.
