Description

Emergency lighting device in inverter system automatic dimming detection circuit

This invention is about an automatic dimming detection circuit for an emergency lighting device in an inverter system, and in particular, refers to an innovative designer of an automatic dimming detection circuit for an emergency lighting device in an inverter system that can not only accurately calculate the luminous flux of a light source, but also is easier and more convenient to use and set up, and can effectively reduce the cost of setting up, and can facilitate the industry to accurately mark the time when the lighting can be used, ensuring the safety of use, and increasing the practical efficacy of the overall implementation and use.

According to the "Fire Safety Equipment Installation Standards for Various Places" in the Fire Regulations, emergency lighting equipment must be installed in various types of multi-purpose buildings. Emergency lighting equipment is generally installed in stairwells and corridors in general companies, buildings or apartments. The emergency lighting equipment mainly has a rechargeable battery connected to the charging circuit, and the rechargeable battery is connected to the light source, and a cut-off switch is connected between the rechargeable battery and the light source. The switching switch is connected to the power-off sensing circuit. Under normal conditions, the charging circuit charges the rechargeable battery to keep the rechargeable battery in a state of sufficient power. In an emergency state [such as power outage, power failure, etc.], the power-off sensing circuit senses that there is no power input and the switching switch can be automatically controlled to switch to a conducting state, so that the rechargeable battery provides the power required for the light source to emit light, thereby performing lighting.

In addition, the emergency lighting equipment can also be directly connected to the lighting fixtures in the building. Under normal circumstances, the mains electricity is directly supplied to the light source of the lighting fixture to provide the required power for lighting and to charge the emergency lighting equipment. In an emergency situation [such as power outage, power failure, etc.], the emergency lighting equipment is switched to supply the required power to the light source of the lighting fixture for lighting.

However, although the above-mentioned light sources can achieve the expected effect of lighting in an emergency, it is also found in its actual operation and use that various types of light sources are generally LED modules. Since the number of LEDs installed on different LED modules is not the same, the power consumed by each LED module with different numbers of LEDs is different, so that the industry cannot accurately mark the available lighting time and the accurate luminous flux on the emergency lighting, which will lead to consumers' misjudgment and affect the safety of use, so that there is still room for improvement in the overall structural design.

Therefore, the creator has taken this into consideration and, based on his rich experience in design, development and actual production in the relevant industry for many years, has further researched and improved the existing technical means to provide an emergency lighting device with an automatic dimming detection circuit in the inverter system, in order to achieve the purpose of better practical value.

The main purpose of this invention is to provide an emergency lighting device in an inverter system automatic dimming detection circuit. Regardless of the number of LEDs installed in the LED module of the light source, the light source is controlled to control the light brightness, thereby controlling the battery to maintain a fixed output current. Not only can the luminous flux of the light source be accurately calculated, but it is also easier and more convenient to use and set up, and can effectively reduce the installation cost. It can also facilitate the industry to accurately mark the time that the lighting can be used, ensure safety in use, and increase the practical efficacy characteristics in its overall implementation and use.

The main purpose and function of this invention's emergency lighting device in the automatic dimming detection circuit of the inverter system is achieved by the following specific technical means:

First, please refer to the first figure for the overall structural block diagram of this creation. This creation mainly includes an emergency lighting device (1); among which:

The emergency lighting device (1) is provided with a battery (11), the battery (11) is electrically connected to a sensor (12), the sensor (12) is used to sense the output current of the battery (11), the sensor (12) is electrically connected to a control unit (13) and a boost circuit (14), the control unit (13) is electrically connected to a dimmer (15), and the dimmer (15) is electrically connected to a light source (16), the light source (16) is a light-emitting diode module, and a plurality of light-emitting diodes are arranged on the light-emitting diode module, so that the control unit (13) receives the sensing signal of the sensor (12) After the signal is received, the control unit (13) outputs a signal to control the dimmer (15) to dim the light source (16) to achieve output power control, and the boost circuit (14) can be a push-pull boost circuit, the boost circuit (14) is electrically connected to a pulse width modulator (17), and the pulse width modulator (17) is electrically connected to the light source (16), so that after the boost circuit (14) boosts the voltage of the battery (11), the pulse width modulator (17) converts the direct current into alternating current and transmits it to the light source (16), so that the light source (16) can emit light.

In this way, the invention is operated and used by setting the maximum current consumption of the battery (11) for the control unit (13) of the emergency lighting device (1) in the initial state, so that when an emergency state [such as power outage, power failure, etc.] occurs and causes a power outage, and the emergency lighting device (1) is started, the sensor (12) can sense the output current of the battery (11), and after the sensor (12) transmits the sensing signal to the control unit (13), the control unit (13) will output a signal to the dimmer (15) according to the output current of the battery (11) sensed by the sensor (12), so that the dimmer (15) dims the light source (16), so that the dimmer (15) output power is controlled so that the output current of the battery (11) is controlled to be maintained at the maximum current consumption that is initially set. At the same time, the boost circuit (14) boosts the input voltage, and then uses the pulse width modulator (17) to convert the direct current into alternating current, which is then transmitted to the light source (16) to enable the light source (16) to emit light. At this time, since the dimmer (15) controls the output power and maintains the output power fixed, the current output time that can be provided by the battery (11) can reach the preset time value, thereby achieving a fixed power outage lighting supply time value, that is, the luminous flux of the light source (16) can be accurately calculated, which can facilitate the industry to accurately mark.

From the above description, it can be seen from the implementation description of the invention that, compared with the existing technical means, the invention mainly controls the light brightness of the light source regardless of the number of light-emitting diodes installed in the light-emitting diode module of the light-emitting source, thereby controlling the battery to maintain a fixed output current. Not only can the luminous flux of the light source be accurately calculated, but it is also easier and more convenient to use and set up, and can effectively reduce the installation cost. It can also facilitate the industry to accurately mark the time that the lighting can be used, ensure the safety of use, and increase the practical efficacy characteristics in its overall implementation and use.
