    • FIG. 1 is a sectional view of an embodiment of the present invention.
    • FIG. 2 is a schematic diagram of a circuit of the present invention; and
    • FIG. 3 is a structural diagram of a demo board of the present invention.
    DETAILED DESCRIPTION OF THE INVENTION
  • The present invention is further described below in detail with reference to the accompanying drawing.
  • As shown in FIG. 1, an electronic candle includes a candle body 1. A cavity 2 is disposed in the candle body 1. A first light-emitting body 3 and an electronic control device 4 for controlling operation of the first light-emitting body 3 are mounted in the cavity 2. The first light-emitting body 3 is an LED and is directly connected to a power source through the electronic control device 4. The first light-emitting body 3 is connected to an optical fiber light guide body 5. The optical fiber light guide body 5 passes through a top of the cavity 2 and extends to an upper surface of the candle body 1 to form an optical fiber light guide candle wick 6. Two second light-emitting bodies 7 are connected below the first light-emitting body 3 in turn and are located in the cavity 2. The second light-emitting bodies 7 are an LED flash lamp and a seven-colored light lamp, respectively. The LED flash lamp and the seven-colored light lamp are connected in parallel, controlled by two gears of a two-gear slide switch respectively, and then connected to the first light-emitting body 3 in series. A black wick light-blocking body 8 formed by wrapping a black plastic sheet is disposed on a bottom of the light guide candle wick 6.
  • As shown in FIG. 2, the present invention relates to an electronic candle, including a mode selection switch, a timing selection switch, a central processor and a light-emitting unit. An input port of the central processor is connected to the mode selection switch, the timing selection switch and a crystal oscillator, and an output port of the central processor is connected to the light-emitting unit. The mode selection switch is a three-position switch, so that a user can select different functions according to requirements, and select different time period modes in combination with the timing selection switch. The crystal oscillator provides an accurate time signal for the central processor, so that the central processor can control, based on setting and according to the mode selected by the mode selection switch and the time signal provided by the crystal oscillator, on/off of the light-emitting unit according to the time period mode. The light-emitting unit includes several LEDs mounted in a candle body and an optical fiber connected to at least one of the LEDs, and the optical fiber passes through a top of the candle body and extends to an upper surface of the candle body to form an optical fiber candle wick.
  • FIG. 3 is a structural diagram of a demo board of the present invention. The upper part of the figure shows a micro-processing system formed by single-chip microcomputers W27C512 and XC3042 and a crystal oscillator, where the crystal oscillator provides a time pulse signal. The middle part of the figure shows a light-emitting unit formed by M2 and M3. M2 is formed by four LEDs L1, L2, L3 and L4 connected in parallel, where L1 is a candle lamp in a soft light flash mode, L4 is a candle lamp for simulating "Mouse Loves Rice" (flickering according to the rhythm of a popular Chinese song), and L2 and L3 are constant lighting lamps. M3 is an optical fiber light-emitting system formed by lamp bulbs D1, D2 and D3, an optical fiber 6 and a switch S6, where D1 flashes yellow light, D2 emits seven-colored light, D1 and D2 are switched over through the two-gear switch S5, and light of the lamp bulbs D1 and D2 is transmitted to the lamp bulb D3 through the optical fiber 6.
  • The lower part of the figure shows a mode selection switch system M1 and a timing selection switch M4. S1 is a three-position selection switch. In position 1 a connection is made to timing selection switches S2, S3, S4 and S5. S7 is a timing level selection jumper switch. A position 2 is a neutral position, where none of the lamps operates. A position 3 is a steady operating mode. In the figure, K1 is a button switch, which is pressed to enter an accelerated test mode. L1 and L4 flash rapidly at a frequency of 2 Hz.
  • In the use of the present invention, when the position 1 of the three-position switch is selected, the timing selection mode may be entered, a timing duration of 4 hours, 5 hours, 6 hours or 8 hours is selected through the jumpers S2, S3, S4 and S5, and a timing level being minute or hour is selected through the jumper S7. When the position 2 is selected, none of the lamps emits light. When the position 3 is selected, all the lamps emit light all the time, which is in the steady mode. The optical fiber light-emitting module according to the present invention may select yellow light or seven-colored light, and can cooperate with a soft flash mode of the LED L1 and the LED L 4 for simulating "Mouse Loves Rice" to provide a romantic and warm atmosphere, which is applicable to various occasions. The present invention has a reasonable circuit design, requires low energy consumption, and can operate for a long time.
  • The above description describes merely a preferred embodiment of the present invention. It should be noted by persons of ordinary skill in the art that modifications and improvements may be made without departing from the principle of the present invention, which should be construed as falling within the protection scope of the present invention.
