When the power of the candle lamp 2 is insufficient and needs to be charged, it is only necessary to place the candle lamp charging device 1 under the indoor light or on a window sill that can be irradiated by sunlight, and the lighting surface of the light energy collection board 12 is placed facing the light source, and then the candle lamp 2 is placed into the accommodating cavity 100 of the housing 11 from the opening 110, and the charging interface 20 is socketed on the charging connector 13 for a period of time to complete the charging of the built-in rechargeable battery of the candle lamp 2.
The candle lamp charging device 1 provided by the embodiment of the present application adopts that the sidewall of the housing 11 is provided with the light energy collection board 12 and the charging connector 13 is arranged in the accommodating cavity 100, such that the light energy is converted into electric energy through the light energy collection board 13, and then electric energy is supplied to the candle lamp 2 through the charging connector 13, so that the built-in rechargeable battery of the candle lamp 2 can be recharged when the power is insufficient, and it can be reused, thereby the technical problem that the candle lamp needs to be powered by a disposable cylindrical battery is solved, and the consumption of the cylindrical battery and the pressure on the environment are effectively reduced, and the candle lamp can be powered by renewable energy.
Further, as a specific embodiment of the candle lamp charging device provided in the present application, the housing 11 is a non-transparent member, that is, the housing 11 is made of non-transparent materials. Specifically, the outer contour of the housing 11 may be cylindrical or prismatic, and the accommodating cavity 100 is provided inside the housing 11. Except for the side where the opening 110 is located, the top and bottom sides of the accommodating cavity 100 and the side away from the opening 110 are closed, so when it is accommodated in the accommodating cavity 100, the candle lamp 2 is in a light-proof semi-enclosed space, and will not be irradiated by sunlight, thereby effectively prevents the wax layer of the candle lamp 2 from melting or the built-in rechargeable battery temperature is too high due to the sunlight, which is beneficial to prolong the service life of the candle lamp 2.

It should be further explained that, from the above table, it can be concluded that the electricity converted by the light energy collection board 12 of the candle lamp charging device 1 in an indoor environment near a window is 0.003 Ampere*28800 seconds=86.4 Coulombs, and 86.4 Coulombs is the minimum total energy for the candle lamp 2 working 4-8 hours, if the lighting area of the light energy collection board 12 is lower than the above-mentioned area, the candle lamp 2 will not meet the usage standard. In fact, the light energy collecting technology under different environments, such as oblique indoor sunlight or direct sunlight outdoors, the energy collected by the light energy collection board 12 of the same area can differ by 100 times or more.

The candle lamp 2 provided by the embodiment of the present application uses a rechargeable battery instead of disposable cylindrical batteries as the power source of the light-emitting element, and the electric energy converted from the light energy collection board 12 is used as the energy source for charging the rechargeable battery through the connecting of the charging interface 20 and the charging connector 13 of the candle lamp charging device 1, thereby the technical problem that the candle lamp needs to be powered by the disposable cylindrical batteries is solved, and the consumption of the cylindrical battery and the pressure on the environment are effectively reduced, and the use cost is reduced.
Optionally, as a specific embodiment of the candle lamp charging device provided in the present application, a voltage monitoring circuit is provided on the control circuit board, and when the rechargeable battery reaches a preset voltage, the voltage monitoring circuit is communicated to the light-emitting element to make the light-emitting element flash at a preset frequency. For example: the rechargeable battery is set to five levels of voltage. When charging is activated, the voltage of the rechargeable battery is at one level, at this time, the voltage monitoring circuit can control the light-emitting element to flash at the slowest frequency, indicating that the charging is activated, and so on. When the power of the rechargeable battery reaches 100%, the voltage of the rechargeable battery is in five levels. At this time, the voltage monitoring circuit can control the light-emitting element to flash at the fastest frequency, indicating that the charging is complete. In this way, according to different voltages corresponding to different flashing frequencies, the user can intuitively distinguish the charging process of the candle lamp 2.
