Detailed Description

The portable lighting system 2 in fig. 1 comprises a lighting lamp 4 and a photovoltaic power supply 6. The illumination lamp 4 is configured to generate light. The photovoltaic power supply 6 is configured to generate electricity based on light (e.g., sunlight).

The illumination lamp 4 and the photovoltaic supply device 6 are separate or separable from each other and can be placed at a distance from each other.

The portable lighting system 2 has a power supply cable 8. The power supply cable 8 is configured to connect the illumination lamp 4 to the photovoltaic power supply device 6, thereby supplying the illumination lamp 4 with the electricity generated by the photovoltaic power supply device 6.

The light 4 has, for example, a power supply opening 10, and the power supply cable 8 has a corresponding power supply connector 12, so that the power supply cable 8 is connected to the power supply opening 10 in a removable manner.

The power supply port 10 is, for example, a USB (Universal Serial Bus) port, a micro-USB port, or a DC (Direct Current) port (or DC connector).

As a variant, the power supply cable 8 is fixedly connected to the illumination lamp 4. Therefore, the power supply cable 8 is connected to the illumination lamp 4 and cannot be disconnected from the illumination lamp 4.

The photovoltaic power supply 6 has, for example, an outlet 14 and the power supply cable 8 has a corresponding outlet connector 16, so as to connect the power supply cable 8 to the outlet 14 of the photovoltaic power supply 6 in a removable manner.

The output port 14 is, for example, a USB port, a micro-USB port, or a DC port.

As a variant, the power supply cable 8 is fixedly connected to the photovoltaic power supply 6. Therefore, the power supply cable 8 is connected to the photovoltaic power supply 6 and cannot be disconnected from the photovoltaic power supply 6.

The illumination lamp 4 has at least one light source 18. Each light source is, for example, an incandescent lamp, an electroluminescent diode (or LED) lamp, or a discharge lamp (e.g., a neon lamp).

The illumination lamp 4 has, for example, a support portion 20. The support 20 is defined as a support and enables the illumination lamp 4 to be placed on a surface, for example, on the ground, on a table or on a shelf.

the support portion 20 has a support surface 20A. The support portion 20 can be placed on a horizontal surface by the support surface 20A. When the illumination lamp 4 is placed on a horizontal surface by means of the support surface 20A of the support 20, the illumination lamp 4 is stable.

each light source 18 is mounted to the support 20, for example by means of a light source connector 22. Light source connector 22 enables power to be supplied to light source 18. The light source connector 22 is, for example, a socket connector or a pin connector.

the illumination lamp 4 has a light emitting section 24. The light generated by the illumination lamp 4 is transmitted to the periphery of the illumination lamp 4 through the light emitting portion 24.

Here, the light emitting portion 24 is located on the side of the support portion 20 opposite to the support surface 20A.

When the illumination lamp 4 is placed on a horizontal surface by the support surface 20A of the support 20, the light emitting portion 24 is located above the support 20.

The light emitting unit 24 is, for example, a cover that covers each light source 18. Such a cover enables protection of each light source 18. Each light source 18 is housed inside the cover.

Therefore, the light emitting portion 24 is configured to spread the light. In this way, the light emitting portion 24 functions as a light diffusing shade. For this purpose, the light emitting portion 24 is translucent, for example. The light emitting portion 24 is made of, for example, translucent glass or translucent plastic, and in particular, white translucent glass or white translucent plastic.

in one embodiment, the combination of the support portion 20 and the light emitting portion 24 conforms to the shape of the illumination lamp 4. The shape of the illumination lamp 4 is generally a parallelepiped, preferably with edges and/or rounded corners.

The portable lighting system 2 has a grip handle 26. The grip handle 26 is mounted on the light 4, more particularly for example on the support 20; and the grip handle 26 enables, for example, gripping the illumination lamp 4 for carrying by a person.

As shown in fig. 2, the grip handle 26 is mounted to rotate (arrow R) about a rotation axis a relative to the illumination lamp 4. Advantageously, the grip handle 26 is rotated at least 180 ° about the rotation axis a, in particular 360 ° about the rotation axis a.

When the illumination lamp 4 is placed on a horizontal surface by means of the support 20, the rotation axis a is, for example, substantially horizontal.

In fig. 2, a plurality of angular positions of the gripping handle 26 are shown, here three: the position of the transport angle (indicated by the solid line) and the other two angular positions (each indicated by the dash-dot line).

Advantageously, the lighting lamp 4 comprises, as an option, a retaining device 28. The holding device 28 makes it possible to fix the gripping handle 26 at one or more angular positions about the axis of rotation.

In an embodiment, the holding device 28 is configured to fix the grip handle 26 at one or more angular positions by means of friction. This friction is, for example, the friction between a first friction portion integral with the illumination lamp 4 and a second friction portion integral with the grip handle 26. Thus, the holding device 28 is a braking device. Application of a force greater than the static friction force generated by the retention device 28 can rotate the gripping handle 28 to a desired position.

In an embodiment, the retaining means 28 enables the grip handle 26 to be retained at any angular position about the axis of rotation a within the angular travel limits of the grip handle 26. The holding device 28 as a detent device enables an infinite number of angular positions.

as a variant, the angular positions are for example discrete and limited in number. For this purpose, the holding device 28 has, for example, one or more positioning pins 30 and one or more holes 32, as shown in fig. 2. The positioning pin 30 is formed on one of the grip handle 26 and the illumination lamp 4, and the hole 32 is formed on the other. Each positioning pin 30 is inserted into the hole 32, so that the grip knob 26 can be fixed at a determined angular position.

In the example shown in fig. 2, the grip handle 26 is provided with a positioning pin 30 for insertion into a plurality of holes 32 provided in the illumination lamp 4. Here, the hole 32 is more particularly provided on the support portion 20. Each hole 32 corresponds to a respective angular position of the grip handle 26 with respect to the lamp 4.

The grip handle 26 has, for example, a grip portion 34 and at least one connecting portion 36. The grip portion 34 is for the user to grip. The connecting portion 36 is used to connect the grip portion 34 to the illumination lamp 4.

Each connection portion 36 is mounted on the lamp 4, in particular on the bearing 20, in rotation about the rotation axis a.

Preferably, at least in the angular position for carrying, the grip 34 is located vertically above the light 4, preferably so that the centre of gravity of the light 4 is located substantially vertically below the grip handle 34.

In this manner, the user can grasp the grip handle 26 in an ergonomic manner, with the weight of the illumination lamp 4 applied vertically below the grip handle 26. The illumination lamp 4 can also be suspended by the grip 34.

advantageously, the grip portion 34 has a notch 38.

the recess 38 is provided for suspending the grip portion 34 from the hanger element by inserting the hanger element into the recess 38. The hanging element is for example a hook. This allows the gripping handle 26 to be prevented from slipping off the hanger element and causing the lamp to fall.

as shown, in one embodiment, the grip handle 26 has two connections 36. The grip portion 34 extends between two connecting portions 36. The grip handle 26 has a generally U-shape with the branches of the U-shape being formed by two connecting portions 36.

The grip handle 26 is mounted on the illumination lamp 4 with the illumination lamp 4 partially received between the connection portions 36.

Each connecting portion 36 has, for example, an end opposite the grip portion 34. This end is connected in rotation about an axis of rotation a to the lighting lamp 4, in particular to the support 20.

When the grip handle 26 is mounted to rotate 360 ° about the illumination lamp 4, the grip portion 34 rotates about the illumination lamp 4 between the two connection portions 36.

Fig. 3 to 5 show the illumination lamp 4 in different configurations. These configurations correspond respectively to different angular positions of the grip handle 26 about the rotation axis a and to different possible uses of the light 4.

In fig. 3, the illumination lamp 4 is oriented with the support surface 20A being substantially horizontal and turned downward. The light emitting portion 24 is positioned above the support portion 20, and the grip handle 26 is rotated such that the grip portion 34 is positioned above the illumination lamp 4.

This configuration enables the illumination lamp 4 to be carried, and the illumination lamp 4 to be placed on a horizontal surface through the support surface 20A of the support 20.

Once the light 4 is positioned on a horizontal surface, the grip handle 26 may be depressed, for example, so that the grip handle 26 does not obstruct the propagation of light generated by the light 4 to the side and above.

In fig. 4, the light 4 is oriented such that the support surface 20A is substantially vertical, and the grip handle 26 is rotated such that the grip 34 is positioned above the support 20.

The illumination lamp 4 can be hung from a hanging member such as a hook, a nail, or the like fixed to a vertical surface by grasping the handle 26. The support surface 20A of the support portion 20 abuts against the vertical surface.

In fig. 5, the direction of the illumination lamp 4 is upside down, and the support surface 20A is directed upward. The illuminating section 24 is located below the support section 20, and the grip handle 26 is oriented such that the grip 34 is located above the illumination lamp 4.

This configuration enables the illumination lamp 4 to be hung on the ceiling by gripping the handle 26, for example, on a hanging member such as a hook fixed to the ceiling.

Advantageously, in an embodiment, the illumination lamp 4 has a plurality of illumination modes. Each illumination mode corresponds to a respective illumination power.

The illumination lamp 4 has, for example, three illumination modes. The first illumination mode has an illumination power of between 40 and 60 lumens, for example 50 lumens. The second illumination mode has an illumination power of between 150 and 190 lumens, for example 170 lumens. The third illumination mode has an illumination power of between 250 and 350 lumens, for example 300 lumens.

Preferably, the illumination lamp 4 comprises control buttons 40. Control buttons 40 enable the user to select a desired illumination pattern. Advantageously, the lighting lamp 4 has only one control button 40.

the control button 40 is, for example, a push button. Each press of the control button enables switching to the next illumination mode.

Optionally, the illumination lamp 4 advantageously has an electrical storage device 42. The electrical storage device 42 enables electrical energy to be stored.

in this manner, the illumination lamp 4 can be operated using the electric energy stored in the electrical storage device 42 provided therein when the photovoltaic power supply device 6 is not generating electricity or when the photovoltaic power supply device 6 is not connected to the illumination lamp 4.

The power storage device 42 is, for example, a battery pack or a storage battery.

Optionally, the portable lighting system 16 is configured to removably connect the lighting lamp 4 into the power distribution network.

To this end, the portable lighting system 16 comprises, for example, a power supply cable (not shown) for connecting the lighting lamp 4 into a power distribution network.

Connecting the portable lighting system 16 to the power distribution network, for example, enables charging of the electrical storage device 42 for subsequent use.

Preferably, the portable lighting system 2 is configured to rapidly charge the electrical storage device 42 through a connection between the lighting lamp 4 and the photovoltaic power supply device 6 and/or a connection between the lighting lamp 4 and the power distribution network.

Alternatively, as shown in fig. 6, the illumination lamp 4 preferably has a charge indication device 60. The charge indication device 60 is configured to provide a visual indication of the state of charge of the electrical storage device 42, i.e., the amount of available power in the electrical storage device 42.

The charge indicating device 60 includes, for example, a plurality of diodes 62. The number of light emitting diodes depends on the state of charge of the electrical storage device 42.

Alternatively, the charge indication device 60 is inactive by default, and the illumination lamp 4 has a charge check button 64. Operation of the charge check button 64 activates the charge indication means 60.

The charge check button 64 is configured, for example, to: the charge indication device 60 remains active as long as the charge check button 64 is activated; and once the charge check button 64 is released, the charge indication device 60 is rendered inoperative.

The charge check button 64 is, for example, a push button or a flip button.

Advantageously, in an embodiment, the lighting lamp 4 has at least one outlet 44. The output port 44 is used to connect an electronic device 46 to the illumination lamp 4 to charge the electronic device 46 with electricity in the illumination lamp 4. The output port 44 is, for example, a USB port or a micro-USB port.

The electronic device 46 connected to the illumination lamp 4 is, for example, a mobile electronic device such as a mobile phone, a smart phone, or a digital tablet computer, or a personal computer; in particular, the electronic device 46 is a portable personal computer.

The photovoltaic power supply 6 includes, for example, a photovoltaic panel 50. Each photovoltaic panel 50 has a receiving surface 52. The receiving surface 52 has one or more photovoltaic cells 54. Each photovoltaic cell 54 is capable of converting light, particularly sunlight, into electricity.

Each photovoltaic panel 50 is, for example, rectangular or square. The photovoltaic panel 50 has a length for example comprised between 150mm and 250mm and a width comprised between 100mm and 200 mm.

In an embodiment, the photovoltaic power supply 6 comprises only one photovoltaic panel 50.

In one embodiment, the photovoltaic power supply 6 transmits, for example, a direct current with a power of 5W maximum and 3W maximum, and a voltage of 10V maximum and 5V maximum.

The length of the power supply cable is for example between 1m and 10m, for example between 2m and 5m, in particular about 3 m.

The above values, whether taken individually or together, enable the portability characteristics of the portable lighting system 2 to be retained as a whole.

In operation, the illumination lamp 4 is connected to the photovoltaic power supply 6 via the power supply cable 8, so as to supply the illumination lamp 4 with electricity generated by the photovoltaic power supply 6, thereby directly supplying each light source 18 in operation and/or supplying the electrical storage means 42 of the illumination lamp 4.

When the illumination lamp 4 has an output 44, an electronic device 46 may be connected to the illumination lamp 4, so that the electronic device 46 is powered by the illumination lamp 4.

when there is no light, for example, no sunlight (such as at night), the power storage device 42 of the illumination lamp 4 supplies power to each light source 18 that is operated, so that the illumination lamp 4 is operated.

The period of time for which the illumination lamp 4 is operated on the basis of the electrical storage means 42 depends, inter alia, on the type of light source (incandescent lamp, LED lamp, discharge lamp, etc.), the illumination power (for example, on the selected illumination mode) and the charge level of the electrical storage means.

In one embodiment, the duration of the illumination lamp 4 is up to 21 hours. When the illumination lamp 4 has a plurality of illumination modes according to the difference in illumination power, the maximum cruising corresponds to the illumination mode with the minimum power.

In one example of use, the illumination lamp 4 is placed in a room 52 of a building 54 (e.g., a house) for illumination of the room 52, for example, and the photovoltaic power supply 6 is placed in the sun (e.g., a window of the building 52 or located outdoors) to be exposed to sunlight.
