Description

TECHNICAL FIELD

[0001] The present invention relates to a lighting device. More specifically, it is an autonomous lighting device, and therefore also a rechargeable lighting device, which can be used flexibly and practically according to the intended use. BACKGROUND

[0002] As is known in the lighting technology sector, in order to avoid the constraints of power cables and to obtain maximum positioning freedom, rechargeable luminaires are increasingly popular.

[0003] Such rechargeable luminaires are increasingly large in size, and therefore also autonomous in terms of aesthetics and able to independently decorate the space in which they are located.

[0004] However, such rechargeable luminaires must be brought close to the charger each time they are discharged, which is inconvenient for the user.

[0005] In fact, no one would willingly move a luminaire of a certain size and weight to another location in the home, where the charger and the socket are located.

[0006] Furthermore, if the luminaire is placed in a position for decorative, i.e. aesthetic, purposes, it must be moved during charging, thus depriving the area of the decoration provided by the luminaire itself during the entire charging process. SUMMARY

[0007] The aim of the present invention is to provide a lighting device that overcomes the problems of the known art.

[0008] Another aim of the present invention is to provide a lighting device that avoids the displacement of an aesthetic luminaire or lighting object.

[0009] Another aim of the present invention is to provide a lighting device that is easy to move, without compromising the aesthetic gradient provided by the luminaire or other lighting object.

[0010] The above aims and others are achieved by the lighting device according to the appended claims. BRIEF DESCRIPTION OF DRAWINGS

[0011] Further characteristics and details will become better understood from the following description, given as a non-restrictive example with reference to the attached tables of drawings wherein:

[0012] Figure 1 is an axonometric view of a lighting device according to the present invention;

[0013] Figure 2 is an exploded axonometric view of a lighting device according to the present invention; and

[0014] Figure 3 is an exploded axonometric view of a lampshade, Figure 1The lighting fixtures can be installed in the lampshade. Detailed Implementation

[0015] Referring to the accompanying drawings, the lighting device of the present invention is indicated by 10.

[0016] The lighting device 10 includes a housing 12, which includes a generally cylindrical lower portion 14 and an upper portion 16 at one end that is a truncated cone, the top of which is closed by a perforated disk 18.

[0017] The lower part 14 and the upper part 16 are made of translucent polycarbonate (milky polycarbonate) to ensure uniform light emission.

[0018] The bottom of the outer casing 12 is closed by the base 20.

[0019] like Figure 2 As shown, above the base 20, inside the housing 12, arranged sequentially from bottom to top are...

[0020] -The lower printed circuit board 22 has light-emitting diodes (LEDs) mounted on it;

[0021] -Battery holder 24;

[0022] - Battery pack 26;

[0023] - The upper printed circuit board 28 has more light-emitting diodes (LEDs) mounted on it.

[0024] The first magnet 30 is arranged between the lower printed circuit board 22 and the base 20.

[0025] To avoid glare, the aforementioned LED lights are installed as follows:

[0026] - The first layer of LEDs facing downwards has the greatest luminous intensity;

[0027] - The second layer of side-facing light-emitting diodes has a medium light intensity, which is further modulated by a translucent outer shell;

[0028] - The third layer of upward-facing LEDs has a medium to low light intensity.

[0029] To reduce glare from the top, the perforated disc 18 is partially covered by a silk-printed portion of small circles of varying diameters.

[0030] A contact switch 32 is arranged in the center of the perforated disc 18, with a corresponding ignition symbol drawn on it.

[0031] The contact switch 32 controls the LED light to turn on and off, and can also change the brightness of the LED light and switch to two available light colors.

[0032] The battery pack 26 is mounted in the battery holder 24 and can be easily removed from the battery holder 24 so that the same battery pack 26 can be replaced if it is used up.

[0033] The lighting device 10 also comprises a charging base 34 having a cable 36 for connection to a power supply.

[0034] The charging base 34 is closed by a cover 38 in order to secure the second magnet 40 to the charging base.

[0035] The first magnet 30 and the second magnet 40 can secure the charging base 34 to the base 20 and charge the battery pack 26.

[0036] At the bottom of the base 20, there are two parallel grooves for receiving two corresponding protrusions on the charging base 34. This further ensures the regular positioning of the base 20 and the charging base 34.

[0037] In addition, the first magnet 30 can also connect the lighting device 10 of the present application to a lamp shade 50 (as shown in Figure 3 Fig. 2).

[0038] In fact, the lamp shade 50 comprises a support 52 to which a light shielding element 54 is secured by means of a ring nut 62.

[0039] Connected to the support 52 is a support 56 in which a third magnet 58 is mounted, which is secured by means of a ring 60.

[0040] The support 56 is adapted to receive the lighting device 10, which is held in place by the first magnet 30 and the third magnet 58.

[0041] During the charging phase, the light bulb emits a weak red light, which changes to green when the charging is complete.

[0042] In addition, the perforated disc 18 slightly protrudes in order to provide a convenient grip when removing the lighting device 10 from the lamp shade 50.

[0043] According to the present application, the lighting device 10 has the function of changing the light output, including the function of changing from an extremely warm color light (2700 K) to a warm color light (3000 K).

[0044] Thus, the lighting device 10 according to the present application can always keep the corresponding lamp shade or other lighting device in the same position, only the same lighting device 10 needs to be moved for charging.

[0045] In addition to the classic lampshade, the lighting device 10 can also be placed in other lighting furniture elements, such as wall elements, which are compatible with the lighting device 10, placed at a height that allows the same lighting device 10 to be pulled out and reinserted.

[0046] With two lighting devices 10, it is possible to ensure the continuous use of the lampshade or other element. While the first lighting device is placed in the respective lampshade, the second lighting device can be charged.

[0047] In addition to what has been described above, other variants and embodiments can be provided, which should be considered as falling within the scope of protection as defined by the claims appended hereto.

[0048] For example, remote control can also be performed by means of a remote control by radiofrequency waves.

[0049] Furthermore, it is possible to use RGB light sources, which emit colored light according to the user's choice.
