The external switch is a light control switch. When the natural light is sufficient, the control bulb is prohibited from starting emergency lighting to save battery power. The external switch can also be a human body infrared sensor switch. When there is a person walking nearby, the light bulb illumination can be started. . The battery charging protection circuit is connected to the battery. The bulb drive circuit is connected to the bulb.

A switch K is provided between the control circuit and the lamp driving circuit for forcibly turning off or turning on the power of the lamp driving circuit.

4.2V output by the battery charger or 12.6V DC can be used as the power required by the bulb. This power source also charges the battery through the battery charging protection circuit. The control circuit determines the output status of the battery charger, and switches the power supply in a timely manner. For example, when the power is off, the control circuit does not detect the DC input, and it automatically switches to the battery to supply power to the lamp.

The external switch may be a human body infrared sensor or a light control switch. These control function switches can be used to control the opening, shading of the bulb.

The control circuit is a information management and issuing command center of the split type mobile constant lamp, and according to the DC state outputted by the battery charger, it is determined whether the light bulb should use the commercial power source or the battery to supply power, and control the brightness of the light bulb. For example, when the utility power is normally supplied, the control circuit transmits the DC power output by the battery charger to the bulb driving circuit to supply power to the bulb illumination, and simultaneously charges the battery through the battery charging line. When there is a power outage, The control circuit can not detect the DC output of the battery charger. At this time, the control circuit will automatically deliver the power of the battery to the bulb, and let the battery supply power to the bulb. At this time, the bulb can become an emergency light when the power is off.

The external switch is connected to the bulb driving circuit, and when the human body infrared sensing switch is used as the external switch, Light bulbs are only activated when there is a nearby activity, which reduces energy consumption. When the external switch is a light control switch (such as a photoresistor), at this time, when the natural light outside the day is sufficient, the light bulb will not start the illumination, and energy waste can be avoided.

When the lamp cap 1 and the lamp body 2 are connected, the battery charger from the lamp cap 1 converts the mains AC power into 4.2V or 12.6V low-voltage DC, commercially available with many general-purpose battery chargers, can convert 100V ~ 240V AC to 4.2V, or 12.6V DC power, this voltage is often used as a charging source for lithium batteries. The battery charger circuit of the present invention converts the alternating current of the commercial power into a charging voltage required for the lithium battery, and at the same time, the DC voltage can also be used to supply power to the bulb. The input to the battery charger can be 100V-240V wide voltage input, but because the light bulb is different from ordinary mobile devices, it will not be used by consumers in other countries, so it is not necessary to apply various AC voltages. We will use a fixed-voltage mains input depending on the voltage of the country where the product is sold, which will reduce the cost of the product. For example, if the product is sold to the US, we will convert 110V to 4.2V or 12.6V DC output charger circuit, if the product is sold in China, convert 220V to 4.2V or 12.6V The DC input charger circuit has the functions of constant current and constant voltage. When charging, the battery inside the lamp body 2 can be properly protected. When the switch K is disconnected, the power supplied to the bulb is cut off. The lamp will not be lit, saving power and extending battery life. When the switch K is turned on, the power is sent to the bulb through the bulb driving circuit. The bulb is illuminated. In addition to the switch K, the external switch can also be used to control the light and dark of the bulb. The control mode and switch of this external switch The difference between K is that K is the power supply for the operator to directly cut off the bulb, and the external switch is turned on by the control circuit after sensing the external signal, or the bulb is turned off or its brightness is controlled.

When the lamp cap 1 and the lamp body 2 are separated or the mains power is cut off, the control circuit detects that there is no 4.2V or 12.6V DC input, the control circuit will automatically turn on the battery's power supply circuit, the light bulb can use the battery to light the light bulb, making the light bulb into emergency emergency lighting. When the switch K is disconnected, the power supplied to the bulb is cut off. The bulb will not be lit. When the switch K is turned on, the power is sent to the bulb through the bulb driving circuit, and the bulb is illuminated. At this time, the bulb can be used as a flashlight, and the power can be turned off at any time. Extend the battery's power supply time.

If the external switch above the bulb is an infrared sensor, it can sense the proximity of the human body and activate the bulb to turn on the illumination. When the human body infrared sensor does not detect someone nearby, the infrared sensor will send a signal to automatically turn off the bulb, which can avoid When the power is off, but there is no one nearby, the light bulb will continue to light up, consuming the battery's power in vain.

If the external switch is a light control switch, when the light bulb senses that the external environment is full of light, whether the control circuit supplies power to the light bulb or not, the light control switch will prohibit the illumination of the light bulb, and the light bulb will not activate the passive illumination, which can save energy.

The switch K is disposed on the lamp body 2, and may be a manual button switch or a touch switch for forcibly turning off the bulb.

The lamp cap of the invention is connected to the fixed lamp holder on the wall of the house. When the lamp cap is connected with the lamp body, the lamp is used as an ordinary light bulb when the mains power is supplied. When the power is cut off, the power supply of the lamp is switched to the battery. Power is supplied and the battery is used as a backup power source. When the lamp cap is separated from the lamp body, the power supply of the lamp is powered by the battery, and the user can use the lamp body as a general flashlight, move and use, and can quickly fix the lamp body 2 by using the magnet on the lamp base 29.

For example, TLY-4201 of Shenzhen Tongliyuan Electronics Co., Ltd. can be used. The mains can be converted to a 4.2V DC output. The TLY-112601 can convert the mains to a 12.6V DC output. Since the bulb is fixed to the wall, the mains is a fixed voltage. We can choose a single applicable mains voltage input without using a 100V-240V universal voltage input. Cost can be reduced, and fewer parts can reduce the chance of failure. The control circuit uses two relays A and B. As shown in Fig. 10, the control coils of the two relays are respectively connected to the positive DC+ and the negative DC- of the low-voltage DC power supply from the battery charger, and the relay A is normally open. The head is connected to the battery pack, and the normally open contact of relay B is connected to the LED bulb group, when DC+ And when DC- has output current, relay A and relay B The reed is sucked down by the control coil. At this time, the normally open contact of relay A is turned on to charge the battery, and the normally open contact of relay B is also turned on. LED bulb group, let the bulb light up. At this time, with the human body infrared sensor, light control switch, the bulb only activates when there is a person walking nearby, or when the external environment is insufficient. When DC+ and DC- When there is no output current, the two relay control coils are powered off, and the reed of the relay will bounce up. At this time, the current of the battery passes through the normally closed contact of the relay B, and the current of the battery pack is delivered to the bulb, so that the bulb It becomes a lighting device for power failure emergency.
