Description

Emergency Energy Saving Light Bulbs

technical field

The utility model relates to a novel energy-saving bulb, in particular to a novel emergency energy-saving bulb.

Background technique

One of the obvious features of traditional light bulbs (including tungsten filament bulbs, fluorescent tubes, and energy-saving lamps) is that they do not have emergency functions. When the power fails, the bulbs will go out immediately. Therefore, emergency lighting is usually installed in places that require emergency lighting. Emergency lighting is provided by Composed of lamps and light bulbs, ordinary traditional light bulbs are currently used. Due to the high power consumption of traditional light bulbs, the emergency time is too short, usually half an hour, and emergency lighting can only provide emergency lighting when there is a power failure, so most of the time is idle In addition, a fatal weakness of emergency lighting is that the indicator light on the emergency lighting only indicates that the battery is in a normal charging state, and it is not sure whether the bulb in the lighting is in normal use. In addition, the traditional bulb has a short life. It is very likely that the emergency lighting will not work after a power failure.

Utility model content

The purpose of the utility model is to provide an emergency energy-saving light bulb with an emergency function, which can play the function of emergency lighting when a power failure occurs, and is especially suitable for LED light bulbs.

The above purpose of the utility model is achieved through the following technical solutions: an emergency energy-saving light bulb, characterized in that it includes a lamp housing, a luminous body, a circuit board, a battery charging control circuit, a rechargeable battery, a lamp holder and electronic components. The luminous body, circuit board, electronic components, rechargeable battery and battery charging control circuit are all arranged in the lamp housing, and the electronic components, luminous body and battery charging control circuit are all arranged on the circuit board, and respectively It is electrically connected with the circuit board, the electronic component is electrically connected with the lamp holder through wires, and the rechargeable battery is electrically connected with the battery charging control circuit through wires.

The light bulb described in the utility model can be used in commonly used lamps at present. The lamp holder is electrically connected with the battery charging control circuit and related electronic components through wires, and the battery charging control circuit is electrically connected with the luminous body and related electronic components through a circuit board. , the bulb shell protects the above components and circuits. Under normal circumstances, the built-in rechargeable battery is continuously charged under the protection of the battery charging control circuit, so that the battery voltage and capacity are always at a reasonable level. When the external power supply is lost, the battery is charged. The control circuit immediately drives the battery to discharge to the luminous body, so that the luminous body starts lighting work, so as to achieve the emergency function.

In the present invention, the luminous body is located on the upper surface of the circuit board, and the electronic components and battery charging control circuit are located on the lower surface of the circuit board. The illuminant is located on the upper surface of the circuit board, which has a better lighting effect, and this structural design also has a better visual effect.

The illuminants can be LED bulbs or other lamp tubes, and a plurality of illuminants are distributed on the upper surface of the circuit board in a dot matrix to ensure sufficient luminous intensity.

The utility model can be designed as an ordinary emergency light bulb, and the capacity of the rechargeable battery can drive the LED to work for 2-3 hours to ensure general emergency needs. The light bulb can only play the function of emergency lighting when the power is cut off, and the LED does not work at ordinary times.

The utility model can also be designed as an energy-saving lighting bulb. The high-capacity rechargeable battery can drive the LED to work for 8 to 10 hours or longer. During the day or when there is no need for lighting, the external power supply can charge the battery. Theory and practice have proved that the battery can be charged The power consumption is very small, especially when the battery is fully charged, the power consumption of the charging control circuit can be ignored. In this way, one charge can guarantee the lighting needs of 8 to 10 hours or more, so as to realize charging during the day and use the battery as a lighting power source at night without An external power supply is required, which can maximize the energy-saving effect; if the solar power generation technology is further improved to a level that can quickly charge the battery, it can realize non-electric lighting and save energy.

The electronic components and the battery charging control circuit described in the utility model can all be implemented by adopting general techniques in the field of electricity.

Compared with the prior art, the emergency energy-saving light bulb of the utility model is equipped with a rechargeable battery and a battery charging control circuit. Under normal conditions, the LED is driven by an external power supply to illuminate and illuminate. When the external power supply is disconnected, the battery charging control circuit immediately drives The battery discharges to the LED to make it glow and illuminate, so as to achieve the purpose that the bulb can still illuminate in an emergency state.
