A waterproof rubber ring is provided at the joint between the cover plate and the panel.

The solar receiving board can also be arranged on the front side, left side or right side of the panel.

Described accumulator can be lithium battery, also can be acid, alkaline accumulator.

The panels can be made of transparent plastic or other transparent materials.

The light guide plate can be made of transparent plexiglass or other transparent materials.

The PCB light board can also be arranged above, on the left side or on the right side of the light guide plate.

The house number signboard can be made of film sheet or light-transmitting plastic plate.

The said house number sign will only be illuminated at night or in low light conditions;

The photosensitive window can be located below, above, left or right of the box body.

The beneficial effects of the solar charging luminous houseplate described in the utility model are:

1. Due to the use of LED bulbs to emit light, the light diverges through the light guide plate and illuminates the house number sign, thereby displaying the design of the house number, which makes the utility model not only simple in structure, long in life, but also lower in requirements for the working environment. Also save electricity;

The solar charging part also uses a battery overcharge protection circuit to ensure that the battery will not continue to charge after it is fully charged, so as not to cause damage to the battery;

2. The battery is equipped with a battery over-discharge protection part, which will automatically stop discharging when the battery is about to run out, so as to prevent damage to the battery due to over-discharge of the battery and affect the service life of the battery.

3. When the battery power changes, the output voltage will also change accordingly, and the constant voltage control part can make the voltage constant, so that the LED bulb can emit light with a constant irradiation intensity.

4. Since the waterproof rubber ring is set at the junction of the panel and the cover plate, the utility model has excellent waterproof performance and can work normally in a humid environment;

5. There is no trouble of replacing the battery, and it is maintenance-free for life.

6. Since the battery used can be a lithium battery with a large capacity, the luminous working time of the solar luminous house plate of the utility model is long;

7. The utility model has a small volume.
