Description

A kind of electric candle

Technical field

The utility model relates to a kind of lighting device, specifically is meant a kind of electric candle with timing function.

Background technology

The LED illuminating lamp is entering into our life gradually, and it has environmental protection, advantage energy-conservation, stable and reliable for performance, and the gesture that replaces incandescent lamp is arranged greatly.Simultaneously along with the raising of expanding economy and people's living standard, people's consumption idea is also changing gradually, not only requires its practicality for the various consumer goods, also requires the judicial convenience, hommization of its aesthetic property and use etc. simultaneously.Purport of the present utility model just is a kind of both artistic and practical, energy-saving safe to be provided and to have the intelligent lighting device of timing function for masses.

The utility model content

The problem that the utility model need solve is the intelligent electronic candle that designs a kind of adjustable brightness, has timing function.

According to the above problem that needs solution, the technical scheme that the utility model is taked is: a kind of electric candle is provided, and it has the wax shell, and LED lamp group is set in the shell, and a control circuit is set to controlling the switch time of LED lamp group.

Described control circuit adopts an integrated chip, and described integrated chip clock pin connects a high-precision quartz crystal oscillator, power end and signal Enable Pin and directly or by resistance connects with the different pins of a driving switch.Stir driving switch, integrated chip power end and signal Enable Pin are sensed voltage change signal, distinguish unlike signal and the time signal that provides in conjunction with the quartz crystal oscillator and then take control corresponding action drives LED lamp group.

LED lamp group in the utility model can comprise form in parallel again after the series connection of single light emitting diode parallel form or a plurality of light emitting diode, these light emitting diodes can adopt a wax shell to install concentratedly, also can divide into groups to be installed on respectively in several wax shells.

The utility model is a kind of novel illumination light fixture, its inner light-emitting diodes pipe jointing wax shell of energy-saving durable that adopts is both artistic and practical, its main feature is to have regularly light on and off function according to people's work and rest custom, people's consumption demand has been catered in this judicial convenience and human oriented design greatly, has good economic outlook.

Description of drawings

Fig. 1 is the utility model control circuit schematic diagram.

The specific embodiment

For the ease of those skilled in the art will recognize that now reaching accompanying drawing in conjunction with the embodiments is described in further detail the utility model.

The utility model comprises the wax shell, is provided with LED lamp group in the shell, and described LED lamp group is connected with a control circuit with timing function.

As Fig. 1, described control circuit comprises integrated chip U1, described U1 clock pin connects a high-precision quartz crystal oscillator Y1, U1 power end, signal Enable Pin are connected with driving switch SW1, the LED lamp group that U1 receives the driving switch variable signal and the time signal that provides in conjunction with the quartz crystal oscillator and then control are connected with the U1 signal output part.

Described driving switch SW1 the 0th, 1 initial gear pin is connected with positive source, the 2nd gear pin by resistance R 1 be connected simultaneously with integrated chip U1 power end and signal Enable Pin, the 3rd gear pin directly is connected with integrated chip U1 power end and signal Enable Pin, described SW1 the 4th, 5 connects power cathodes, the 6th, 7 pin ground connection.

Driving switch SW1 among the embodiment has three gear: OFF (pass) shelves, DIM shelves (low bright), ON shelves (highlighted), respectively the anodal situation about being communicated with 0,1 pin or 1,2 pin or 1,2,3 pin of corresponding power.The LED that promotes to have when SW1 is allocated to DIM or ON shelves by the OFF shelves varying number is luminous, and for example the LED of U1 control half is luminous during DIM, and the whole LED of control is luminous during ON, realizes the illumination of different brightness.

DIM or ON shelves all have timing function, regularly are allocated to these shelves with switch from the OFF shelves and begin to calculate, and luminous 8 hours of LED extinguished 16 hours, and 24 hours is one-period, so repeatedly circulation.

Described chip U1 operating voltage is 6V, and the electric candle of finished product adopts dry cell power supply.

Need to prove; foregoing circuit only is the utility model preferred embodiment; protection domain of the present utility model is not limited thereto, and not breaking away from any impartial variation of under the utility model design prerequisite circuit being done and modification, all belongs to protection domain of the present utility model.
