[Prior Art] In view of the occurrence of global warming, the main cause of warming is the production of excessive carbon dioxide by humans. Most carbon dioxide production comes from human demand for lighting, such as lighting in a burning manner. If the demand for lighting is solved by means of electricity, the production of carbon dioxide can be reduced. Among them, candles are the most commonly used lighting medium for human beings, not only for the use of pure lighting, but also for creating an atmosphere. Many types of electronic candles are currently available on the market, usually only simple illuminators with a candle shape, and are simply used to provide illumination. However, the use of the above mentioned candles is sometimes intended to create an atmosphere. Among the conventional technologies or products, there is no electronic candle device that provides an atmosphere. Therefore, the present invention provides a light-emitting device having a situation mode, which simulates the state of a real candle as the airflow changes, and achieves an aesthetically pleasing purpose.

In another example, the present invention provides a lighting device in addition to the above. In particular, the sensing device senses the flow rate of the airflow and corresponds to the sense signal. When the flow rate of the airflow reaches a predetermined flow rate, the processing circuit enters the Hume state, causing the light to be extinguished.

4WBEAR/07001TW M326988 In another embodiment, the present invention provides a lighting device that receives a sensing signal in addition to the components mentioned above, and further based on a predetermined algorithm or lookup table (look-up Table), causing the illumination device to produce the brightness change to simulate the illumination of a conventional candle.

The object, the embodiments, the features, and the advantages of the present invention will be more apparent from the following description of the preferred embodiments. FIG. For a more detailed description, reference may be made to the following description and in conjunction with the drawings of Figures 1A to 4. Figure 10 is a diagram of a light-emitting device according to an embodiment of the present invention: In this embodiment The illuminating device 10 includes a sensing device 12, an electric and a light source 16. The sensing device 12 is configured to detect the flow rate of the airflow 18,

4WBEAR/07001TW M326988 Flow rate change, flow rate, or flow rate change, and corresponding to the sense signal 20. The processing circuit 14 controls the light source 16 based on the sense signal 20 such that the source 16 produces a change in brightness.

In one embodiment, processing circuit 14 receives sensing signal 20 and further varies the brightness of illumination device 16 to simulate the illumination of a conventional candle based on a predetermined algorithm or look-up table. The light source 16 can be, but is not limited to, a light-emitting diode, and can be implemented in a commercially available light bulb, as long as the brightness of the light source 16 can be changed according to the control of the processing circuit 14. The processing circuit 14 further includes a signal amplifier 142 and an analog digital converter 144 (shown in Figure 1B). The signal amplifier 142 is configured to amplify the sensing signal 20 generated by the sensing device 12, for example, to amplify the small sensing signal 2 through the signal amplifier 142 to a sensing signal 2 可接受 acceptable by the processing circuit 14. The analog-to-digital converter 144 provides an input analog signal, and outputs a digital signal 22 via a signal conversion. For example, the analog-to-digital converter 144 outputs a square wave signal as a complete period of the square wave signal of the digital signal digital signal 22 (also referred to as a duty cycle ( D = y Cycie)) The packet contains a positive cycle 222 and a negative cycle. At positive period 222, source 16 receives a positive voltage and source 16 provides illumination; conversely, period f4?, source 16 receives a negative voltage and source 16 is extinguished. In particular, during the duty cycle, the positive period 224 and the negative period 224 occupy the ratio I 2 ::, and the source 16 provides illumination, extinguishing, and flicker. For example, one of the heart buckles is a positive cycle, for example, when the positive cycle 224 occupies 8〇% of the work.

4WBEAR707001TW M326988 The period k ′ has a time of 0·8 seconds, and the light source 16 provides illumination. Conversely, when negative cycle 224 occupies 80% of the duty cycle (positive cycle 224 occupies 2% of the duty cycle), source 16 provides illumination for only 0.2 seconds. Preferably, when the flow rate, flow rate change, flow rate, and amount of money detected by the sensing device are changed, the ratio of the negative period 224 is larger; and when the flow rate of the air flow is changed, the flow rate is changed, and the flow rate is changed. When the flow rate changes by more than a predetermined value, the processing circuit 14 even enters a sleep state, causing the light source 16 to be extinguished. Referring to Fig. 1B, a light-emitting device 1A of the above embodiment will be described. In this embodiment, the sensing device 12 generates a sensing signal 2 corresponding to the airflow 18. In one embodiment, the amplitude 202 of the sense signal 20 is used to indicate the flow rate or flow rate of the airflow. In another embodiment, the frequency 2 〇 4 of the sense signal 2 用以 is used to indicate a change in flow rate or flow rate of the air flow. Referring to Figure 2, there is shown a schematic view of a light-emitting device 30 having a chirped candle shape in accordance with another embodiment of the present invention. In the present embodiment, the candle-shaped light-emitting device 3A includes a candle body 32. The candle body 32 further includes a sensing device 12, a processing circuit 14, a light source 16, and a power supply unit 322.

The sensing signal 20 of the sensing device 12 generates static electricity 126 according to the static electricity generating unit 124. The processing circuit 14 causes the light source 16 to produce a change in brightness based on the sensing signal 20. Light source 16 provides an illumination, such as light source 16 being a light emitting diode. The power supply unit 322 is used to supply power required for the illumination device. For example, the power supply unit 322 includes a primary battery, a secondary battery, an external power supply, or a combination thereof. Electricity

4WBEAR/07001TW M326988 The source unit 322 is preferably a power source rechargeable battery used by a general household such as a dry battery, an electric or a mobile information device sold on the market.

The device 12 has a static electricity generating unit 124, for example, 70,124 is a styrofoam ball, a rotating ball, a ball of yarn, or a material that is easy to produce 126. Taking the styrofoam ball as an example, the static electricity 126 is generated by friction, so that when the airflow 18 passes through the air hole 122, the Gulong ball placed in the sensing device=crashes and strikes the sensing device 12 to generate static electricity. 126. = Flow rate of flow stream 18, flow rate change, flow rate, or flow rate change will affect the amount of charge of static electricity 126. The sensing device 12 generates a sensing signal 20 according to the amount of charge of the static electricity 126 and supplies it to the processing circuit 14.

For example, the sensing device 12 is not a cylinder, and may further include a tapered shape, a spiral shape, or any other shape. As long as the shape and size of the sensing device 12 can satisfy the induced airflow 18, the static electricity 126 is generated by the sensing device 12 due to the disturbance.

In addition, the faster the flow rate of the air stream 18, the higher frequency of the acoustic signal 36 is produced. Conversely, the slower the flow rate, the lower the frequency of the acoustic signal. Sensing device 12 produces a sense signal 20 corresponding to the frequency change produced by airflow 18 on air vent 34.
