Description

A kind of colored intelligent background lamp apparatus of LED

Technical field

It is specifically a kind of to utilize sensor and monolithic the utility model relates to the protection field of the colored intelligent background light of LED Machine realize LED background light intelligentized control method, controlled using photo resistance lamps and lanterns switch and light and shade variation, accomplish light intensity compared with Lamps and lanterns will not automatically turn on when strong, and when light is weaker automatically turns on the effect of sensor.

Background technique

With the high speed development of science and technology, the continuous improvement of living standards of the people, green, environmental protection, energy conservation, healthy high-quality Life is the yearning and pursuit of people, and people are no longer content with the lives of singsong.The appearance of LED lights, to the life of people Work brings many changes.LED illumination System is applied to extensively in our lives, so that people's lives are more abundant more It is color.But being controlled using people are still relied primarily on manually for current LED light, always will appear lamp in some occasions and does not have when not in use People closes, or needs to open inconvenience when light, and not only waste electricity, also brings certain trouble to people's lives.

Utility model content

For above situation, the utility model provides a kind of colored intelligent background lamp apparatus of LED, it is therefore intended that utilizes biography The intelligentized control method of sensor and chip microcontroller LED background light controls switch and the light and shade variation of lamps and lanterns using photo resistance, Accomplish that lamps and lanterns will not automatically turn on when light intensity is stronger, and is automatically turned on the effect of sensor when light is weaker.

The utility model adopts the following technical solution to achieve the goals above: a kind of colored intelligent background lamp apparatus of LED, It is made of power module, driving circuit, single-chip microcontroller, external timing module, clock display module, sensor: passing through photo resistance The variation of resistance value goes to change the level of single-chip microcontroller pin in the environment of different illumination intensity, and CPU is allowed constantly to detect the pin Level change decides whether to light LED lights according to the level, by clock-embedded module, can taking human as go adjust Save the period of color lamp work.By the double control of clock and photo resistance, then be not in it is indoor nobody when, automatically will LED color background lamp is lighted, and is resulted in waste of resources.

The power module is powered using the D.C. regulated power supply of 15V.

The driving circuit uses 74HC07 chip, and when the I/O of single-chip microcontroller mouth exports high level, 7407 output reaches To 5 to 7 volts, then the undertension at both ends is to drive LED operation.To reach the light on and off using single-chip microcontroller control LED.

The single-chip microcontroller uses AT89C51 chip, is the core of the design.

The external timing module selects DS1302 clock chip as timing chip, the I/O pin and list of the chip I/O mouthfuls of piece machine of some pin interaction, to achieve the effect that timing.

The clock display module, using 1602 liquid crystal displays, for showing the working time of color lamp.

The sensor is intelligentized most crucial embodiment, selects photo resistance as control switch.

The utility model has the beneficial effects that: a kind of colored intelligent background lamp apparatus of LED, by photo resistance in difference The variation of resistance value goes to change the level of single-chip microcontroller pin in the environment of intensity of illumination, and the level for allowing CPU constantly to detect the pin becomes Change, decide whether to light LED lights according to the level, by clock-embedded module, can taking human as de-regulation color lamp The period of work.By the double control of clock and photo resistance, then be not in it is indoor nobody when, automatically by LED colour Background light is lighted, and is resulted in waste of resources.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of the colored intelligent background lamp apparatus of LED of the utility model.

Fig. 2 is that a kind of structure of the sensor intelligent control switch of the colored intelligent background lamp apparatus of LED of the utility model is shown It is intended to.

Appended drawing reference: (1) power module；(2) single-chip microcontroller；(3) driving circuit；(4) external timing module；(5) clock is aobvious Show module；(6) sensor.

Specific embodiment

It is described further below in conjunction with attached drawing.

The structural schematic diagram of the colored intelligent background lamp apparatus of a kind of LED as shown in Figure 1, including power module (1), single-chip microcontroller (2), driving circuit (3), external timing module (4), clock display module (5), sensor (6) composition: power module (1) uses The D.C. regulated power supply of 15V is powered, and by photo resistance, the variation of resistance value goes to change monolithic in the environment of different illumination intensity The level of machine (2) pin, allow CPU constantly to detect the level change of the pin, determines driving circuit (3) according to the level Whether light LED lights, by being embedded in external timing module (4), can taking human as the work of de-regulation color lamp period.Pass through The double control of the sensor (6) of clock and photo resistance composition, then be not in it is indoor nobody when, LED colour is carried on the back automatically Scape lamp is lighted, and is resulted in waste of resources.

The power module (1) is powered using the D.C. regulated power supply of 15V.

The single-chip microcontroller (2) uses AT89C51 chip, is the core of the design.

The driving circuit (3) use 74HC07 chip, when the I/O of single-chip microcontroller mouth output high level when, 7407 it is defeated Reach 5 to 7 volts out, then the undertension at both ends is to drive LED operation.To reach the light on and off using single-chip microcontroller control LED.

The external timing module (4) selects DS1302 clock chip to be used as timing chip, the I/O pin of the chip and Some pin interaction of single-chip processor i/o mouth, to achieve the effect that timing.

The clock display module (5) uses 1602 liquid crystal displays, for showing the working time of color lamp.

The sensor (6) is intelligentized most crucial embodiment, selects photo resistance as control switch.

It is illustrated in figure 2 a kind of structural schematic diagram of the sensor intelligent control switch of colored intelligent background lamp apparatus of LED, When illumination is stronger, the numerical value of photo resistance partial pressure is not enough to allow triode ON, so the P1.3 pin of single-chip microcontroller is high at this time Level；When light intensity is weaker, the resistance value of photo resistance can be gradually increased, thus its partial pressure numerical value can also be gradually increased, when its two When end voltage is enough to make triode ON, P1.3 foot detects that level is low level.According to the level detected from P1.3 foot Variation, when CPU detects that the signal of P1.3 foot for low level, can be lighted LED lights by control signal；When CPU is detected Signal to P1.3 foot is high level, can be extinguished LED lights by control signal.To achieve the effect that intelligent control.
