Detailed ways

An uninterruptible electric light bulb, which includes: a bulb head 1, a casing 2, an electronic control board 3, a battery 4, a light source 5 and a lampshade 6; through the accommodating space formed by the bulb head 1, the casing 2 and the lampshade 6, the An electronic control board 3, a battery 4 and a light source 5 are installed and connected to each other via wires.

Fig. 1 is the exploded view of the utility model continuous electric light bulb, and this continuous electric light bulb comprises a bulb head 1, a casing 2, an electronic control panel 3, a battery 4, a light source 5 and a lampshade 6; 2 and the housing space formed by the lampshade 6, in which the electronic control board 3, the battery 4 and the light source 5 are accommodated, and are connected to each other through wires.

The peripheral portion of the bulb head 1 is provided with a peripheral thread 12, and the top is a convex point 11, and an insulating material is used to separate the peripheral thread 12 of the bulb cap 1 from the convex point 11 at the top, so as to form two contacts, which is different from the general traditional light bulb. The lamp holders are the same, so they can be applied to the traditional bulb holder 10 (as shown in Figure 7), making it easy to install, easy to replace, and no additional construction is required, which is the reason for using this type of lamp holder.

The shell 2 is an annular hollow thin shell with a hole on the top and bottom. The upper hole 21 can be matched with the periphery of the bulb head 1. The matching method is tight fitting, adhesive bonding or welding. The lower hole 22 can be connected to the lampshade 6 .

The lampshade 6 protects the light source 5 and its internal circuit, and makes the light emitted by the light source 5 uniform. Therefore, the lampshade 6 provides an accommodating space to accommodate components such as the light source 5, the battery 4 and the electronic control board 3, so the lampshade 6 is also a hollow thin shell, similar to a cover, which has only one opening 61, and the opening 61 It can cooperate with the lower hole 22 of the housing 2 . The shape of the lampshade 6 can be spherical, spiral or 3U, as shown in Fig. 4, Fig. 5 and Fig. 6 respectively. In this embodiment, the housing 2 and the lampshade 6 are connected by screw threads, and can also be connected by tenon or tenon rotation.

As shown in FIGS. 2 a and 3 a , the electronic control board 3 includes a power supply circuit 31 , a charging circuit 34 , a power failure detection circuit 33 and a power switching circuit 32 . The commercial power connected by the bulb head 1 is connected to the power supply circuit 31 through wires, and the power supply circuit 31 converts the AC power into a DC power supply to supply the required power for the power failure detection circuit 33, the rechargeable battery 41 and the light source 5. The charging circuit 34 is connected to the external rechargeable battery 41 via wires, so that the rechargeable battery 41 can be charged to maintain the stored power of the rechargeable battery 41 . The power-off detection circuit 33 is used to detect whether the external AC power supply is truly power-off. If there is a power-off, a signal can be sent to the power switching circuit 32 to make the power switching circuit 32 perform power switching. The power switching circuit 32 is used for power switching. The continuous electric light bulb of the present utility model has two power sources, one is that the commercial power is converted into a DC power source through the power supply circuit 31, and the other is the power source provided by the rechargeable battery 41. The mains power is converted into a DC power supply via the power supply circuit 31. When the mains power supply is actually cut off (not caused by the switch being closed), the power supply switching circuit 32 switches the power supply originally provided by the power supply circuit 31 to the light source. The rechargeable battery 41 provides power to the light source to maintain its light.

When the power stored in the rechargeable battery 41 is exhausted, it can be recharged through the charging circuit 34 for recycling.

The light emitting source 5 is composed of a single or a plurality of light emitting diodes. Because the brightness of a single light emitting diode is not enough to be used for lighting, a plurality of light emitting diodes are assembled to increase the brightness so that it can be used for general lighting. When the brightness of the light-emitting pole body can reach the luminous brightness of the above-mentioned plurality of light-emitting diodes, it can be replaced by one light-emitting diode; the light-emitting diodes on the market today have various types of light-emitting, so the utility model can have different light-emitting colors due to different requirements , and the light source 5 with light-emitting diodes of different colors can have a variety of color choices.

Fig. 1 and Fig. 7 are the exploded view and the wiring diagram of the utility model continuous electric light bulb, one end of the AC power supply is connected with a light indicator power switch 9, and then connected to one end of the bulb holder 10 by the power switch 9, the other end of the AC power supply One end is directly connected to the other end of the bulb holder 10, and the bulb head 1 of the continuous electric light bulb of the present utility model is locked in the bulb holder 10, the bulb head 1 is connected to the housing 2, and the housing 2 is connected to the housing space formed by the lampshade 6 , the accommodating space accommodates the electronic control board 3, the battery 4 and the light source 5, the wires are connected to the electronic control board 3 through the bulb head 1, and two groups of wires are separated from the electronic control board 3, and one group of wires is connected to the battery 4, Another group of wires is connected to the light source 5 .

2a and 3a are circuit block diagrams and structural diagrams of the utility model rechargeable continuous light bulb.

When AC power is input 8 to the power circuit 31 , the power circuit 31 converts the AC power into DC power to provide the power required by the charging circuit 34 , the power switching circuit 32 and the power failure detection circuit 33 .

The AC power supply also has another input in the power-off detection circuit 33 to detect whether the AC power supply is truly cut off. When the power supply was cut off, the light indicating power switch 9 would have no current to flow through, and therefore, when the light indicating power switch 9 was closed, no weak current would flow through, so the power failure detection circuit 33 could not detect When the signal is received, it is a real power-off.

The charging circuit 34 charges the rechargeable battery 41. The rechargeable battery 41 provides a power supply for the power switching circuit 32, which is a backup power supply. Another power supply provided by the power switching circuit 32 is the power supply circuit 31, which is the main power supply. When the power detection circuit 33 does not output a signal to the power switching circuit 32, the power switching circuit 32 directly outputs the DC power provided by the power circuit 31 to the light source 5; when the power failure detection circuit 33 outputs a signal to the power switching circuit 32, It means that the AC power is in a power-off state, and then the power switch circuit 32 outputs to the light source 5 from another backup power source, that is, the rechargeable battery 41 .

Another embodiment of the utility model continuous light bulb includes: a bulb head 1, a shell 2, an electronic control board 3, a battery 4, a light source 5 and a lampshade 6; The space contains the electronic control board 3, the battery 4 and the light source 5, and is connected to each other through wires.

Its structure, assembly connection method and function thereof are identical with the aforementioned rechargeable continuous electric light bulb, only difference is that it is non-rechargeable, so used battery 4 is disposable batteries such as general dry cell i.e. carbon-zinc battery or alkaline battery.

The electronic control board 3 is slightly different from the aforementioned rechargeable continuous light bulb. Please refer to FIG. The commercial power is connected to the power supply circuit 31 via wires, and the power supply circuit 31 converts the AC power into a DC power supply to supply the power required by other circuits and the light emitting source 5 . The battery circuit 7 is connected to the battery 4 via wires, and the battery 4 is a general dry battery, that is, a carbon-zinc battery or an alkaline battery, etc., as a backup power supply. The power-off detection circuit 33 is used to detect whether the external AC power supply is truly power-off. If there is a power-off, a signal can be sent to the power switching circuit 32 to make the power switching circuit 32 perform power switching. The power switching circuit 32 is used for power switching.

The non-rechargeable continuous light bulb of the present utility model has two power sources, one is that the commercial power is converted into a DC power source through the power circuit 31, and the other is the power source provided by the battery circuit 7. The required power is provided by the commercial power through the power supply circuit 31. When the commercial power is really cut off (not due to the switch being closed), the power switching circuit 32 will provide the light source with the original power supply circuit 31. The power supply is switched to the power provided by the battery circuit 7 for the light emitting source to maintain its light emission.

The battery 4 is a general dry battery, that is, a carbon-zinc battery or an alkaline battery, etc. If the power of the battery 4 is exhausted, a new battery 4 can be replaced to provide the original function.

2b and 3b are circuit block diagrams and structural diagrams of the utility model non-rechargeable continuous light bulb.

The AC power input 8 is in the power circuit 31 , and the power circuit 31 converts the AC power into a DC power to provide the power required by the power switch circuit 32 and the power failure detection circuit 33 .

The AC power supply 8 also has another input in the power-off detection circuit 33 to detect whether the AC power supply is truly powered off. The so-called real power-off means that the power-off is not caused by the light indicating that the power switch 9 is closed, but when an external AC power supply is switched off. When a power outage occurs, no current flows through the light indicating power switch 9, and therefore, when the light indicating power switch 9 is closed, no weak current flows, so the power failure detection circuit 33 cannot detect signal, at this time it is a real power-off.

The battery circuit 7 provides a power supply for the power switching circuit 32, which is a backup power supply, and another power supply circuit 31 that provides power for the power switching circuit 32 is the main power supply. Therefore, when the power failure detection circuit 33 does not output a signal When feeding the power switching circuit 32, the power switching circuit 32 directly outputs the direct current provided by the power supply circuit 31 to the light source 5; when the power failure detection circuit 33 outputs a signal to the power switching circuit 32, the alternating current is in a power-off state. Then the power switch circuit 32 outputs to the light source 5 from another backup power source, namely the battery circuit 7 .

The invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The above-described embodiments are therefore considered to be illustrative rather than restrictive in all respects, and the scope of the present invention is indicated by the appended claims rather than by the foregoing description, and appears within the equivalent meaning and range of the claims All changes of are therefore meant to be incorporated therein.
