Double-control multi-charge multi-purpose LED lamp

Abstract

The invention relates to a double-control multi-charge multi-purpose LED lamp. The double-control multi-charge multi-purpose LED lamp comprises a lithium ion power supply module, a control circuit and an LED light emitting diode, the lithium ion power supply module is connected with the control circuit, and the LED light emitting diode is connected with the control circuit; the control circuit is provided with a control terminal, a power supply terminal and a test terminal; a solar battery or an electric supply adapter is connected with the control circuit through the control terminal, and the test terminal is connected with the control circuit; the power supply terminal is used for an external power supply for charging the lithium ion power supply module, supplying power for external equipment and testing. The double-control multi-charge multi-purpose LED lamp is long in illumination time and various in charging mode; the double-control multi-charge multi-purpose LED lamp has a light control function, has the function of an electric supply emergency lamp, has an alarming function and has a loop-open type alarming function, and the double-control multi-charge multi-purpose LED lamp is turned off automatically when there is electricity and turned on automatically when power off.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a dual-control, multi-charge and multi-purpose LED lamp. Background technique [0002] With the promotion of solar energy applications, more and more solar lighting equipment using light control. However, most of these devices are controlled by photodiodes or phototransistors, and rechargeable batteries, photodiodes or phototransistors, control circuits and LED light-emitting diodes are all installed in lamps that are exposed to sunlight for a long time, that is, rechargeable batteries, Photodiodes or phototransistors, control circuits and LED light-emitting diodes are often in a very high temperature environment, which will adversely affect the life of photodiodes or phototransistors, control circuits and batteries. [0003] With the promotion of the application of LED light-emitting diodes, there are more and more lighting products such as flashlights, headlights, work lights, garden ...

AI Technical Summary

Problems solved by technology

At present, these products generally have two problems, one is that the lighting time is not long enough, and the other is that the batteries used are easily damaged

The main reasons are: the capacity of the battery used is not large enough, which is the root cause of the insufficient lighting time; the charging circuit of the product is simple and has no protection function, so it is difficult to ensure that the battery will not be overcharged when charging

These products mostly use acid batteries. Although this kind of battery is relatively cheap, this kind of battery has small volume capacity, memory function, poor self-discharge performance, cannot be overcharged, cannot be overdischarged, and cannot be short-circuited.

[0004] In addition, with the development of economic construction, there are more and more places that need to use emergency lights. At present, some products with emergency light functions appear on the market, but because these products use a simple charging circuit rectified by a capacitor step-down diode, plus There is no measure to prevent battery overcharging. In order to make the product can be used normally, it can only be realized by charging no more than a certain amount of time.

In this way, this product cannot be used as a real emergency light, because the real emergency light requires to be connected to the power supply no matter how long it is used.

In addition, although there are many products using LEDs at present, these products have single functions and cannot be used for other purposes except lighting.
