Description

A kind of light-operated circuit of LED ceiling light

Technical field

The utility model belongs to LED lighting technical field, especially relates to a kind of light-operated circuit of LED ceiling light.

Background technology

LED light source is widely used as a kind of known generally acknowledged green illumination, LED ceiling light is to select a kind of ceiling light of LED as light source, it is arranged on the ceiling of the public arena such as house interior or corridor, because light fixture top is more flat, install near roof, similarly be to be adsorbed on roof, so be referred to as ceiling light.This LED light fixture because its light efficiency is high, the long and safety and environmental protection of little power consumption, life-span, extensively get consumer reception, and in light-operated circuit when design of LED ceiling light, making product make in use whole illuminator have more hommization and epoch atmosphere is that the fashion of current LED ceiling light illumination application is pursued.

Utility model content

Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of light-operated circuit of LED ceiling light, and it is simple in structure, reasonable in design, it is convenient to realize, and uses simple operation, make illuminator have more hommization, be convenient to promote the use of.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of light-operated circuit of LED ceiling light, it is characterized in that: comprise controller module and the power circuit module to each electricity consumption module for power supply, the input of described controller module is connected to light sensor, between described controller module and described light sensor, be connected to for the signal of light sensor output is amplified, the signal conditioning circuit of filtering and A/D conversion process, described signal conditioning circuit is by the amplifying circuit joining successively, filter circuit and A/D change-over circuit form, the output of described controller module is connected to the ON-OFF control circuit module for controlling LED lamp module, described controller module and delay circuit module join, described delay circuit module also joins with described ON-OFF control circuit module, the quantity of described LED lamp module is multiple and is no less than two, each is organized described LED lamp module and is composed in series by the identical or different LED lamp of multiple quantity.

The utility model compared with prior art has the following advantages:

1, the utility model is simple in structure, reasonable in design, and it is convenient to realize, and uses simple operation.

2, the utility model is by delay circuit the suddenly power-off in the situation that, and LED ceiling light can not extinguish at once, makes illuminator have more hommization.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is the structured flowchart of the light-operated circuit of a kind of LED ceiling light of the utility model.

Description of reference numerals:

1-controller module; 2-power circuit module; 3-light sensor;

4-amplifying circuit; 5-filter circuit; 6-A/D change-over circuit;

Embodiment

As shown in Figure 1, the utility model comprises controller module 1 and the power circuit module 2 to each electricity consumption module for power supply, the input of described controller module 1 is connected to light sensor 3, the signal being connected to for light sensor 3 is exported between described controller module 1 and described light sensor 3 amplifies, the signal conditioning circuit of filtering and A/D conversion process, described signal conditioning circuit is by the amplifying circuit 4 joining successively, filter circuit 5 and A/D change-over circuit 6 form, the output of described controller module 1 is connected to the ON-OFF control circuit module 7 for controlling LED lamp module 8, described controller module 1 joins with delay circuit module 9, described delay circuit module 9 also joins with described ON-OFF control circuit module 7, the quantity of described LED lamp module 8 is multiple and is no less than two, each is organized described LED lamp module 8 and is composed in series by the identical or different LED lamp of multiple quantity.

Operation principle of the present utility model is: the real-time sensed light signal of light sensor 3 is also exported to signal conditioning circuit by detected signal, amplifying circuit 4, filter circuit 5 and A/D change-over circuit 6 in signal conditioning circuit amplifies, exports to controller module 1 after filtering and A/D conversion process signal successively, controller module 1 carries out analyzing and processing to signal, by comparing with the default optical signal value being stored in controller module 1, then regulate the brightness of LED lamp module 8 by ON-OFF control circuit module 7 simultaneously; In the time running into the situation of unexpected power-off, controller module 1 can not disconnect ON-OFF control circuit module 7 by delay circuit module 9 immediately, and LED lamp module 8 can continue a period of time of throwing light on, and finds other emergency lightings to people's time enough.

The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification of above embodiment being done according to the utility model technical spirit, change and equivalent structure change, and all still belong in the protection range of technical solutions of the utility model.
