The present disclosure relates to a technical field of lighting devices, and in particular to a lamp holder and a magnetic lighting device that is easy to power.
Lamp holders refer to appliances that enable light transmission, light distribution, and altering of the light distribution, each including all parts required for fixing and protecting a light source, excluding the light source, and wiring accessories necessary for connecting to a power supply. Currently, lighting devices encompasses residential lighting, commercial lighting, industrial lighting, road lighting, landscape lighting, and special-purpose lighting, and the lighting devices are also categorized into wall-mounted lighting devices and handheld devices according to mounting methods. Specifically, the wall-mounted lighting devices are typically considered to be wall lamps, most of which are mounted on ceilings at a considerable height from the ground. In the prior art, most of the wall-mounted lighting devices connect the lamp holders to bulbs via magnetic attraction.
Nowadays, the wall lamps rely on mains electricity, once the mains electricity is interrupted, the wall lamps cannot function, which may bring inconvenience to people. To address such issue, emergency wall lamps are provided in the market. Current emergency wall lamps generally connect a battery-powered bulb to a corresponding lamp holder via the magnetic attraction, which is capable of functioning without the mains electricity. However, such design still has some drawbacks, the battery-powered bulb needs to be frequently charged, and needs to be removed from the corresponding lamp holder when every time being charged, which is complex and inconvenient. Moreover, for people with limited manual dexterity, there are also safety hazards, such as falling off from a height. Therefore, there is room for improvement.
A main purpose of the present disclosure is to provide a lamp holder and a magnetic lighting device being easy to power, aiming to solve a technical problem of safety incidents caused by frequently detaching of a bulb of the magnetic lighting device for charging.
In order to achieve the main purpose, the present disclosure provide the lamp holder configured to cooperate with the bulb, including a lamp holder housing and a first magnetic assembly. A charging protection board is disposed in the lamp holder housing and is electrically connected to an external circuit. The first magnetic assembly is configured to attract the bulb for fixing the bulb on the lamp holder housing. A charging connector is disposed on the charging protection board, the charging connector is configured to insert into and connect with a charging interface of the blub, so as to supply power to an internal power supply of the bulb.
Furthermore, the lamp holder further includes a lamp holder bottom plate, the lamp holder bottom plate is detachably disposed at an opening end of the lamp holder housing for sealing the opening end of the lamp holder housing.
Furthermore, an inner wall of the lamp holder housing is connected to the lamp holder bottom plate through limiting components, and an outer peripheral surface of the lamp holder bottom plate abuts against an inner wall surface of the lamp holder housing.
Furthermore, first ends of a first part of the limiting components are fixedly connected to the inner wall surface of the lamp holder housing and second ends of the first part of the limiting components are connected to the lamp holder bottom plate through screws, or, the first ends of the first part of the limiting components are connected to the inner wall surface of the lamp holder housing through the screws and the second ends of the first part of the limiting components are fixedly connected to the lamp holder bottom plate. First ends of a second part of the limiting components are fixedly connected to the inner wall surface of the lamp holder housing, second ends of the second part of the limiting components face the lamp holder bottom plate, limiting shafts are disposed on a first surface of the lamp holder bottom plate facing an interior of the lamp holder housing corresponding to the second ends of the second part of the limiting components.
An interval is defined between the limiting shafts and the second part of the limiting components, a first part of the charging protection board is clamped in the interval, and a second part of the charging protection board is sleeved around peripheries of the first part of the limiting components connected to the lamp holder bottom plate.
Furthermore, a groove is defined on a second surface of the lamp holder bottom plate facing away from the interior of the lamp holder housing, and the first magnetic assembly is disposed in the groove.
The present disclosure further provides the magnetic lighting device, including the bulb, a second magnetic assembly, and the lamp holder as foregoing. The second magnetic assembly is disposed on the bulb. The bulb and the lamp holder are attracted to each other through magnetic attraction between the first magnetic assembly and the second magnetic assembly. A lighting assembly and the internal power supply are disposed in the bulb, the internal power supply is electrically connected to the lighting assembly, a circuit in the lighting assembly is partially and electrically connected to the charging protection board in the lamp holder, so as to supply the power to the internal power supply of the bulb by the lamp holder.
When the external circuit is powered off, the internal power supply is configured to supply the power to the lighting assembly.
Furthermore, the second magnetic assembly is embedded in a top portion of the bulb.
Furthermore, the bulb includes a lampshade, the charging interface is disposed at one end of the lampshade attracted to the lamp holder, the charging connector on the charging protection board passes through the charging interface to be electrically connected to the lighting assembly.
Furthermore, the lighting assembly includes a printed circuit board (PCB) and light emitting diode (LED) lamp beads, the LED lamp beads are disposed on the PCB, terminal is disposed on the PCB, and the terminal is configured to be in contact with the charging connector.
Furthermore, an external interface is defined on an exterior of the lampshade for power supplying and data transmission.
According to the present disclosure, the first magnetic assembly is disposed on an exterior of the lamp holder housing, so that the lamp holder housing and the bulb are attracted to each other to fix the bulb on the lamp holder housing, since the charging protection board is disposed in the lamp holder housing, the charging connector is disposed on the charging protection board, and the charging connector is configured to insert into and connect with the charging interface of the blub when the bulb is fixed on the lamp holder housing, the lamp holder is capable of supplying the power to the internal power supply of the bulb, thereby achieving lighting. Specifically, the charging connector is inserted into the charging interface, so that an activity range of the charging connector is limited, thereby enabling more stable electrical connection between the charging connector and internal structures pf the bulb, current transmission is more stable, so that the lamp holder is capable of supply the power to the bulb electrically connected thereto. In this way, when the lighting assembly in the bulb fails, only a new bulb needs to be replaced to allow for continued lighting without replacing an entire lighting device of the magnetic lighting device, which significantly reduces a cost of the magnetic lighting device. Moreover, the internal power supply in the bulb is configured to store the power and independently supply the power to the lighting assembly. Therefore, when mains electricity is interrupted, the lamp holder cannot transmit the power, the internal power supply in the bulb supplies the power to the lighting assembly in the bulb for emergency lighting, it should be noted that such design of the magnetic lighting device does not require users to frequently detach the bulb from the lamp holder for charging to achieve the emergency lighting, thereby greatly reducing the safety incidents caused by frequently detaching of the bulb of the magnetic lighting device.
