Multiple power input luminaire

This creation is about a multi-power input luminaire, especially a luminaire that can input multiple power sources, enabling multiple power supplies to be powered simultaneously or separately without interference and short circuit conditions, and to reduce losses and provide a stable light source.

The power supply of general lighting equipment can only be connected to a single input power supply. Therefore, when the general lighting power supply is unable to supply power due to power failure, other standby emergency power sources (batteries, generators, UPS, solar cells, etc.) must be utilized. Power supply, because only a single power input, often cause user inconvenience. In order to improve the connection of only a single input power source, there is a conventional power supply system. When two power supply systems are simultaneously powered, a power supply system is selected by configuring a relay mode to isolate the two power supply systems before power supply to the load. There is no interference or short circuit condition, but the configuration of the relay can only supply the power of the same nature and the same voltage, and cannot supply the power of different natures and voltages at the same time, which still causes the limitation of power supply. In addition, when a single power supply is input, when the mains supply and the standby emergency power supply (battery DC power supply, generator) are connected to the power supply, the UPS (continuous power system) must be installed to achieve the normal power supply performance of the mains and the standby emergency power supply, and then the UPS is removed. In addition to the excessive size of the equipment room, the UPS's own installation cost and maintenance cost are not low, and when switching power supply, the conversion loss is relatively increased, which often results in waste of energy and does not meet the economic cost requirements. In view of this, this creation provides an improved luminaire for the utility and its His standby emergency power supply (battery, generator, UPS, solar battery, etc.) can be powered simultaneously or separately without interference and short-circuit conditions, and the multi-power supply can still maintain normal power supply when it is simultaneously input. It works and has the effect of constant power.

The main purpose of this creation is to provide a multi-power input lamp, which uses a power parallel device to connect multiple input power sources. The power supply parallel device uses a rectifier circuit to rectify the multi-input power supply, and all the positive poles are connected to the positive pole and the negative pole to the negative pole, and connected in parallel as an output terminal. To the load (light-emitting part (LED, fluorescent tube or tungsten)), when multiple power supplies are supplied at the same time or separately, there is no interference or short circuit. The power input AC/DC can be directly input. For example, the DC power supply such as the battery is directly input. It is not required to be converted into AC and then input through the UPS, so as to eliminate the configuration of the UPS (continuous power system) and reduce the power loss to achieve stable power supply. Target person.

In order to achieve the above objectives, the multi-power input lamp provided by the present invention comprises a lamp body, a power parallel device electrically connected to the multi-input power terminal, and a power output terminal connected to the lamp body, which are connected by a power parallel device. Input power, so that the mains and other emergency power supplies (batteries, generators, UPS, solar cells, etc.) can be powered at the same time without interference and short circuit conditions, and multiple power supplies are simultaneously input when they are suddenly powered off. It can maintain normal power supply operation and has the effect of continuous power.

The present invention will be described by way of a preferred embodiment (taking dual power input as an example). This description explains the structure and steps of the present invention, and is merely illustrative and not intended to limit the creation. Therefore, the present invention may be widely practiced in other embodiments in addition to the preferred embodiments in the specification.

Please refer to FIG. 1 to FIG. 3 , which is a preferred embodiment of the multi-power input lamp used in the system for dual-purpose emergency lighting, mainly comprising a lamp body 1 , a power parallel device 2 and a The lamp body 10 has a lamp housing 10 and a bottom cover 11. The lamp housing 10 defines an accommodating space 100 for the power supply parallel device 2 to be fixed and then provided with a bottom cover. 11 is closed; and the power parallel device 2 (refer to FIG. 2) is provided with two mains and battery input terminals 20, 21 and two bridge rectifiers 22, 23, which are used by the bridge rectifiers 22, 23 The power input from the power input terminals 20 and 21 is rectified, and the positive pole is connected to the positive pole and the negative pole is connected to the negative pole, and is connected in parallel to the power output terminal 3 and then connected to the load, that is, the electric lamp 4 (refer to FIG. 2).

Working principle (please refer to Figure 4), when the mains is not powered off, the mains input power from the power input terminal 20, at this time the battery power input terminal 21 is not powered, the power supply is rectified by the bridge rectifier 22, and the positive pole is connected to the positive pole. The negative pole is connected to the negative pole, and is connected in parallel to the power output terminal 3 and then connected to the load, that is, the electric lamp 4, and the electric lamp 4 will be controlled by the wall switch 5 to be bright or not; if the utility power is cut off (refer to Fig. 5), the battery power supply is input. 21 forced power supply, the power The source is rectified by the bridge rectifier 23, the positive pole is connected to the positive pole and the negative pole is connected to the negative pole, and is connected in parallel to the power output terminal 3 and then connected to the load, that is, the electric lamp 4, so that the electric lamp 4 is bright, and is not controlled by the wall switch 5; The power supply will not be powered at the same time. If the power failure detection switch 6 is faulty (as shown in Figure 6) or the power supply and the battery are powered by the two power input terminals 20 and 21 respectively, the power supply on both sides passes through the bridge rectifier.
