Description

An adapter for LED lamp and charger

Technical Field

The utility model relates to the technical field of LED lamp charging equipment, in particular to an adapter for LED lamps which also serves as a charger.

Background Art

There are usually two ways to power high-power LED lights on the market, namely using lithium batteries or using AC power adapters. Power adapters are standard products for LED lights and are usually used indoors or outdoors where AC power is available. When working outside, carry fully charged lithium batteries. If the lithium batteries are exhausted, replace them with more fully charged batteries or return to a location with AC power to charge the batteries after stopping work. This method of use requires a special lithium battery charger to charge the batteries.

With the increasing number of high-power LED lamps in the market, more and more generators and high-power energy storage batteries are used in external environments to provide AC power to LED lamps. At present, the main sources of AC outdoor power for LED lamp adapters on the market are the above two power sources. Although the existing charging products combine AC and DC power supply methods, the two power supply methods are simply superimposed, that is, only one of AC or DC can be used for power supply, and when the power stored in the DC energy storage battery is exhausted, it needs to be charged separately. When using it, it is necessary to frequently observe the power stored in the DC energy storage battery to ensure that it can power the LED lamp when there is no AC power. When the user forgets to check, it is easy to have insufficient power in the DC energy storage battery when there is no AC power, which affects the normal use of high-power LED lamps.

Utility Model Content

The utility model aims to provide an adapter which can also serve as a charger for an LED lamp. The adapter can charge an external battery when the LED lamp is not in use, thereby avoiding the need for the user to observe the storage capacity of the battery many times, thereby improving the versatility of the adapter, serving as a charger, improving the charging capacity, enhancing the user's experience, and being highly practical.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

An adapter for an LED lamp that also serves as a charger, comprising a shell, hanging plates are arranged on both sides of the shell, a control unit is arranged inside the shell, an input interface, an output interface and a control switch are arranged on the shell, the input interface, the output interface and the control switch are all electrically connected to the control unit, the input interface is connected to an AC adapter, the control unit comprises a charging module and a discharging module, the discharging module outputs direct current to the LED lamp through the output interface, the charging module charges a battery installed on the hanging plate through the hanging plate, and the control unit can charge the battery when the LED lamp is not in use.

Preferably, a plug hole adapted to the battery is provided on the hanging plate.

Preferably, the shell is formed by splicing a plurality of cover plates.

Preferably, a lifting lug is provided on the top of the shell.

Preferably, when the AC adapter is powered on to supply power to the LED lamp, the discharge module outputs direct current to the LED lamp through the output interface; when the AC adapter is powered on and the LED lamp is turned off, the charging module charges the battery through the hanging board; when the AC adapter is not powered on, the battery is boosted by the control unit to supply power to the LED lamp.

In the utility model, the adapter also serves as a battery charger, which is a dual purpose device, avoiding the need for users to carry multiple chargers and adapters when using, and is easy to use and carry. The control unit is set to have three working states, which can convert AC to DC to directly power the LED light, boost the power in the battery to a specified voltage to power the LED light, and charge the battery when AC power is connected but the LED light is not in use, ensuring that the battery is in a sufficient power state, and can also power the camera in the event of a sudden power outage, thereby enhancing the user's experience.

DETAILED DESCRIPTION

The utility model is further described below in conjunction with the accompanying drawings:

As shown in Figures 1, 2, 3, 4 and 5, an adapter for LED lamps and a charger comprises a housing 1, and hanging plates 2 are arranged on the left and right sides of the housing 1. The housing 1 is composed of multiple cover plates fixedly spliced by fasteners, which is convenient for disassembly, assembly and maintenance. A hanging ear 3 is fixedly arranged on the top of the housing 1, and the hanging ear 3 can be used to fix the adapter. A plug hole adapted to the battery is arranged on the hanging plate 2. When the battery (lithium battery for the camera) is hung on the hanging plate 2, the plug hole contacts the charging end corresponding to the battery to charge the battery.

A control unit 4 is provided inside the housing 1, and an input interface 5, an output interface 6 and a control switch 7 are provided on the housing 1. Specifically, the input interface 5, the output interface 6 and the control switch 7 are all provided on the top of the housing 1. The input interface 5, the output interface 6 and the control switch 7 are all electrically connected to the control unit 4, and the control switch 7 is used for the adapter to turn on and off the power of the LED lamp. The input interface 5 is connected to the AC adapter through a cable, and the AC adapter transforms 220V DC into 48V DC and inputs it into the input interface 5. The output interface 6 is connected to the LED lamp through a cable to power the LED lamp.

The control unit 4 includes a charging module 40 and a discharging module 41. A voltage identification circuit board is also provided on the control unit 4. The voltage identification circuit board can identify the voltage of the battery installed on the hanging board 2, and can charge both 4 strings of lithium-ion batteries and 7 strings of lithium-ion batteries. The discharging module 41 outputs 48V DC power to the LED lamp through the output interface 6 to power the LED lamp. The charging module 40 charges the battery installed on the hanging board 2 through the hanging board 2, and the control unit 4 can charge the battery during the interval when the LED lamp is not using electricity.

The adapter is provided with three working states. The first working state: when the AC adapter is connected to the input interface 5, the discharge module 41 directly outputs the 48V DC power input by the AC adapter to the LED lamp through the output interface 6 to power the LED lamp, and controls the on and off of the LED lamp through the control switch 7. In this state, the battery installed on the hanging board 2 is in a state of waiting for charging. The second working state: when the AC adapter is connected to the input interface 5, the brightness of the LED lamp is zero or in a closed state (that is, the LED lamp does not consume power). At this time, the charging module 40 charges the battery through the hanging board 2, avoiding the disadvantages of traditional separate carrying and charging, and also avoiding the disadvantages of traditional cameras that need to reinstall the battery before they can be used after a sudden power outage, thereby ensuring the stability of the power supply of the camera when in use. In the third working state, when the AC adapter is not powered on or powered off, the control unit 4 boosts the battery mounted on the hanging board 2 to 48V, and outputs the 48V voltage to power the LED lamp. When the battery itself is 48V, no boost is required.

The above embodiments are only some descriptions of the concept and implementation of the utility model, and are not intended to limit the concept and implementation of the utility model. Under the concept of the utility model, technical solutions that have not been substantially changed are still within the scope of protection.
