The working principle and the beneficial effects of the technical scheme are as follows: in emergency lighting systems, an emergency converter (sometimes also referred to as a converter, ballast or driver device) is used to provide a supply current to an emergency lighting device for a predetermined time in the event of a mains power failure. In the event of a mains power failure, the current supply is maintained or activated for a nominal service time using energy stored in an energy storage device, such as a rechargeable battery. The nominal service time defines a battery discharge duration during which the emergency converter unit is required to drive the emergency lamp with a predetermined drive current. The predetermined drive current is the minimum load current that enables the connected lamp to complete its task of providing an emergency lamp level for a rated service time.
In many systems, the functionality of the emergency light system must be tested at predefined intervals by performing a functional test, and the functionality must be continuously monitored during operation of the emergency device using built-in test equipment. After such testing or after the device encounters a power failure, the energy storage device must be recharged.
The charging parameters (charging current and/or voltage) and charging mode, including the charging voltage characteristics and/or charging current characteristics, depend on the type of energy storage device and sometimes on the operating conditions. Typically, niCd batteries are charged at a constant current, while NiMh batteries benefit from pulsed charging.
To cover different types of batteries and applications, the converter unit may be designed to be charged using different charging parameters and/or charging modes, wherein the charging parameters and/or modes are selected by a user by operating a jumper switch or DIP switch built into the converter unit or connected to the converter unit via terminals of the interface.
However, the additional switches and terminals increase the overall cost of the converter unit and involve considerable space at the housing assembly of the emergency converter unit device.
The present embodiment adopts a scheme in which at least one charging parameter and/or charging mode is selected by connecting two poles of a status indicator lamp to two of the terminals S1 to S3, wherein a first charging current of a constant current charging mode is assigned to a first connection variant, wherein the status indicator lamp is connected to the terminals S1 and S2, a second charging current of the constant current charging mode is assigned to a second connection variant, wherein the status indicator lamp is connected to the terminals S1 and S3, and a pulsed current charging mode is assigned to a third connection variant, wherein the status indicator lamp is connected to the terminals S2 and S3.
Status indicator lights are selectively connected to two of the terminals S1 to S3 by the manufacturer or user in order to adapt the charging process to the type of battery connected to the terminals B1, B2. The control device stores a charging current and a charging mode to each connection variant, determines the connection variant by detecting loads between the terminals S1 and S2, the terminals S1 and S3, and the terminals S2 and S3 or a predetermined resistor after applying the mains power to the input terminal L, N and before starting the charging process, and sets the charging current and the charging mode according to the determined connection variant. Furthermore, based on the determined connection variant, the control device outputs a signal/voltage to the terminals S1 and S2, the terminals S1 and S3, or the terminals S2 and S3 to drive the status indication lamp to indicate the charging process or battery full as described above during normal operation.
A switch (normally open contact) with which the user initiates a test mode may be connected in parallel to the status indicator lamp, wherein the control means detects whether a short circuit is applied between the terminals S1 to S3 and initiates a test mode when a short circuit is detected, the status indicator lamp being connected to the terminals, in which test mode a power failure is simulated, and the lighting is supplied with a predetermined driving current using the battery for a predetermined time (battery discharge duration).
The detection may be performed by a microcontroller of the control device or by a discrete circuit of the control device. The detection circuit of the control device may be used to detect a short circuit connected in parallel to the status indicator lamp and a connection of the status indicator lamp to the terminals S1 and S3 or the terminals S2 and S3, for example.
A first power supply voltage and a second power supply voltage are applied to the terminals, respectively, and a first signal for detecting whether the status indicator lamp is connected to the terminals S1 and S3 is applied to the terminals, or a second signal for detecting whether the status indicator lamp is connected to the terminals S2 and S3 is applied to the terminals. In case a first signal is applied to the terminals from, for example, a microcontroller of the control device, transistor Q1 is turned on, transistor Q4 is turned off, and when the status indicator light is not connected to terminals S1 and S3, the zener diode is turned on, current passes through the zener diode and the resistor, and the voltage drop across the resistor is detected by the microcontroller at the terminals. On the other hand, when the status indicator lamp is connected to the terminals S1 and S3, the diode is not turned on, and the voltage drop across the resistor becomes zero. Further, when a switch connected in parallel to the status indicator light is operated by a user, a short circuit is caused to be applied between the terminals S1 and S3, the transistor Q3 is turned off, and a signal detected at the terminals by the microcontroller is switched from a low voltage level to a high voltage level.
In the case that the second signal is applied to the terminals, transistor Q1 is turned on, transistor Q3 is turned off, and when the status indicator light is not connected to terminals S2 and S3, the diode is on, current flows through the diode and the resistor, and the voltage drop across the resistor is detected by the microcontroller at the terminals. On the other hand, when the status indicator lamp is connected to the terminals S1 and S3, the diode is not turned on, and the voltage drop across the resistor becomes zero. Further, when a switch connected in parallel to the status indicator light is operated by a user, a short circuit is caused to be applied between the terminals S2 and S3, the transistor is turned off, and a signal detected by the microcontroller at the terminal is switched from a low voltage level to a high voltage level. The signals output by the terminals are evaluated by the microcontroller to control the charging process and initiate the test mode, respectively.
The user connects the connection lines of the status indicator light and the switch to terminals S1 to S3, which may be bolt terminals or spring clips.
The status indicator light and the switch may be connected by one of three adapters, wherein each adapter has three pins for connecting terminals S1 to S3 on one side of the adapter and four terminals for connecting two connection lines of the switch and two connection lines of the status indicator light on the other side of the adapter. In the adapter, four terminals are connected to three pins according to a first connection variant, a second connection variant or a third connection variant. Further, a terminal for the second switch may be provided on the other side, and the adapter may be configured to connect the second switch in parallel to the status indicator lamp as described above. With the adapter, incorrect connections can be prevented, wherein the correct adapter is recommended by the manufacturer or sold with the battery.
Alternatively, a single adapter may provide a tree connection variant by a DIP switch built into the adapter, wherein the DIP switch is operated by a user to connect a pin and four or more terminals, thereby establishing one of the three connection variants.
The number of selectable charging parameters and/or charging modes may be increased by using Light Emitting Diodes (LEDs) as two-pole status indicator lamps, wherein the control means is then configured to detect the polarity of the connected light emitting diodes and to detect to which two of the terminals S1 and S2, the terminals S1 and S3 and the terminals S2 and S3 the light emitting diodes are connected, and to set the charging parameters and/or charging modes based on a table indicating the charging parameters and/or charging modes to each combination of polarity and connection variants. The polarity may also be changed/set by DIP switches.
In another embodiment, the present embodiment provides an emergency lamp, including the intelligent power supply conversion device of the emergency lamp.
The working principle and the beneficial effects of the technical scheme are as follows: the scheme adopted by the embodiment is that the intelligent power supply conversion circuit used by the emergency lamp can realize current collection/self-electricity automatic identification conversion. When the battery module is connected, the lamp is converted into a self-power working mode; and (5) pulling out the battery module, and automatically switching the lamp to a current collection working mode.
