Description

Christmas lamp or the energy-conservation timer of rainbow electronic lamp

Technical field

The utility model relates to a kind of decorative lamp controller, particularly a kind of Christmas lamp or the energy-conservation timer of rainbow electronic lamp.

Background technology

Some decorative lamp; as Christmas decorative lamp; neon light; lamp string etc.; in use; uninterrupted round the clock bright lamp; need to rely on the manual control switch to use; cause the electric energy waste, in the decorative lamp industry, utilize transformer low voltage power supply or high voltage source power supply to support single-chip microcomputer timework at present; dispose photo resistance in addition; utilize sunlight daytime; the startup of the strong darkness control single chip computer of the light at night; timing; close, use inconvenience, timing error is bigger; when power supply stops; single-chip microcomputer is in stopped status can't be according to program timing operate as normal, perhaps in use extraneous light-illuminating, or the environment for use brightness is when big; photo resistance is interfered and produces misoperation; put and make the single-chip microcomputer timing error, the timing error does not reach regularly energy-saving benefit.

Summary of the invention

At the problems referred to above, the purpose of this utility model is to provide a kind of easy to use, energy-conservation electric energy-saving timer that is used on Christmas decorative lamp or neon light, the lamp string.

The technical scheme that the utility model adopted is:

Christmas lamp or the energy-conservation timer of rainbow electronic lamp, comprise that voltage input circuit, rectification circuit, timing function select circuit, timing master device and be used for the drive circuit in break-make lamp string source, the output of rectification circuit connects the timing master device, timing function selects the output of circuit to connect the timing master device, and the output of timing master device connects the drive circuit that is used for break-make lamp string source.

Further, this timer also includes back-up source, and the output of described back-up source connects the timing master device, can solve external power supply.

The beneficial effects of the utility model are: use the lamp string of above-mentioned electric energy-saving timer, it is easy to use, and the operating time can be set, and to periodic duty afterwards in second day, need not operation every day, easy to use, reliable, regularly good energy-conserving effect is saved social resources.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a schematic block circuit diagram of the present utility model;

Fig. 2 is the novel physical circuit figure of this use.

Embodiment

With reference to Fig. 1, Fig. 2, Christmas lamp of the present utility model or the energy-conservation timer of rainbow electronic lamp, comprise that voltage input circuit, rectification circuit, timing function select circuit, timing master device and be used for the drive circuit in break-make lamp string source, the output of rectification circuit connects the timing master device, timing function selects the output of circuit to connect the timing master device, and the output of timing master device connects the drive circuit that is used for break-make lamp string source.Wherein, as shown in Figure 2, rectification circuit is made up of diode D1～D4 and capacitor C 4～C7, uses for the timing master device; The timing master device is made up of single-chip microcomputer SN8P2501A, clock crystal oscillator XL1, capacitor C 9, C8.

In addition, this electric energy-saving timer also includes back-up source, the output of described back-up source connects the timing master device, this back-up source by battery pack BT1 and diode D5, D6 form positive and negative outage power supply circuits, this circuit is used for when external power supply cuts off the power supply giving single-chip microcomputer SN8P2501A work by battery pack BT1 power supply.

As preferred implementation, as shown in Figure 2, described timing function is selected circuit to include selection key and is selected display, selection key is connected with the timing master device with the selection display, further, described selection key is individual palpation key K1, and it connects an input port of timing master device; Described selection display is a plurality of light-emitting diodes, and as LED 1, LED2, LED3, the LED4 of 6,8,12,24 hours different times of expression timing, it connects the single-chip microcomputer output port of timing master device respectively.

In addition, the described drive circuit that is used for break-make lamp string source comprises controllable silicon or the relay that connects the timing master device, the control end of controllable silicon or relay is arranged at lamp string and presses on the delivery outlet, as shown in Figure 2, connect driving triode Q1 at the P5.4 of single-chip microcomputer SN8P2501A end, and be connected with relay J D1B by triode Q1.

Timer of the present utility model is used for Christmas decorative lamp, neon light etc., and described input circuit voltage can be by AC/DC 12V～240V, and operating frequency is 50Hz～80KHz.This timer can comprise housing, attaching plug, power line is arranged on the housing and be connected the socket that light fixture is used, and is directly switched on to socket through Single-chip Controlling relay or controllable silicon by interchange or direct current that the plug place inserts, and power supply is to lamp string working voltage.Single-chip microcomputer has full-automatic 24 hours circulation timing programs, timing functions and selects, the timing section has different choice such as 2H～24H, need not to add startup, the closing motion that photo resistance utilizes the sunlight control single chip computer, avoid the error of sunlight intensity size irradiation and the light-struck interference of environment for use and produce misoperation.Built-in back-up source is for intelligent single-chip microcomputer electricity consumption, solve external power supply stop power supply and make single-chip microcomputer can't timing, shut down, cause timing out, problems such as misoperation.

Certainly, the invention is except above-mentioned execution mode, and other equivalent technical solutions also should be within protection range of the present utility model.
