Sunshade umbrellas are leisure products frequently used in people's daily life. At present, there are a wide variety of sunshade lighting umbrellas among which those having a plurality of LED lamp beads mounted on the ribs are commonly used. However, during the production, the necessity of drilling on every one of the ribs makes the strength of the ribs degraded so that the sunshade umbrellas are likely to be damaged. Mounting these LED lamp beads into the bores is both time and labor consuming. Furthermore, to realize the desired lighting effect, a lot of lamp beads are needed. However, the excessive lamp beads lead to excessive circuits, causing the mounting more complicated. On the other hand, once an individual lamp bead burns or an individual circuit breaks down, the use of the whole umbrella will be influenced and the maintenance is particularly inconvenient.

The utility model will be further described in details as below with reference to the accompanying drawings.
A novel lighting umbrella is provided, including a lower hub 2, an upper hub 6 secured on the top of a shaft 3, and ribs, one end of each of long ribs 4 being articulated with the upper hub 6 while the other end thereof supporting a panel, one end of each of short ribs 1 being articulated with the lower hub 2 while the other end thereof being articulated with the middle portion of one of the long ribs 4. A notch 101 is formed in one or both of the long ribs 4 and the short ribs 1. There may be one or two notches 101 in each of the long ribs 4 or the short ribs 1, each notch 101 having a light emitting device provided therein. The light emitting device comprises a light guide bar 14 clamped inside the notch 101, and a clamping flange 102 that can clamp the light guide bar 14 to prevent it from falling off is provided on the edge of the notch 101. The light guide bar 14 is provided with a light source on its end surface. The light source includes an SMD LED lamp 103 and a PCB lamp panel 104, which are connected to each other by welding, and the light source is secured on a fixed base 7. A jack 701 is formed on the cross-section of a side plate of each notch 101 corresponding to that of the fixed base 7, and the fixed base 7 is inserted into the jack 701 to be secured on the ribs and sleeved with a stopper 8 for protection. A through hole 702 is formed inside the fixed base 7, the PCB lamp panel 104 is inserted into and secured in the through hole 702 inside the fixed base 7, that is, the PCB lamp panel may be secured on the fixed base 7. The SMD LED lamp 103 clings to the light guide bar 14, and after the PCB lamp panel is well connected to and powered by the power supply, light from the SMD LED lamp enters the light guide bar 14 and forms a light band by continuous refraction and reflection inside the light guide bar, thereby realizing the purposes of lighting and beatifying the environment.
A second wire connecting plate 601 is provided inside the upper hub 6, a first wire connecting plate 201 is provided inside the lower hub 2, and a light source wire 5b is arranged inside a short rib 1; one end of the wire is connected to the first wire connecting plate 201, while the other end thereof passes through an articulator by which a long rib 4 is articulated 1 a short rib 1 and through the long rib 4 to be electrically connected to the second wire connecting plate 601 and the second wire connecting plate 601 is electrically connected to a switch 5 and a power supply 5a. When there is no light guide bar provided on a long rib 4, it is unnecessary to provide the second wire connecting plate 601 inside the hub 6 accordingly, that is, one end of the light source wire 5b arranged inside a short rib 1 is electrically connected to the first wire connecting plate 201 while the other end thereof passes through an articulator by which a long rib 4 is articulated with a short rib 1 and through the long rib 4 to be electrically connected to the power supply 5a that is externally connected to a switch 5.
When there is no light guide bar on a short rib 1, it is unnecessary to provide the first wire connecting plate 201 and the light source wire 5b inside the hub 2 accordingly, that is, the second wire connecting plate 601 inside the hub 6 is electrically connected to the switch 5 and the power supply 5a. The three specific circuit connection manners as described above may supply power to the light emitting device better.
There is at least one light guide bar 14 clamped on any one of the long ribs 4. When there are many light guide bars 14, two fixed bases 7 for fixing the corresponding light guide bars are provided at positions where the light guide bars inside the long ribs 4 are butt jointed with the light guide bars, and the butt-joints are sleeved with a wrapper 401. It is better to provide a plurality of light guide bars on the long ribs to realize uniform light entering the light guide bars 14 from the SMD LED lamp, good refraction and reflection effects easier formation light band, and better lighting and environment beatification effects.
Each of the upper hub 6 and the lower hub 2 of the novel lighting umbrella provided by the utility model consists of a hub cap and a hub holder; an annular ring 9 having a plurality of wire lead-out holes 10 on its outer circle is provided inside the hub holder, with two symmetrical trapezoidal limiting blocks 11 being provided on any one of the wire lead-out holes 10; and, an arc bayonet 12 for clamping decorative parts or the power supply is provided on the inner circle of the hub panel, with a corresponding arc bump 13 being provided on the decorative parts connecting ring.
The switch wire 501 of the switch 5 may be connected to the power supply 5a through a notch 101 on any one of the long ribs 4, or connected to the power supply 5a through the interior of the shaft 3. That is, the switch S may be directly hung on a certain long rib 4 or secured on the shaft 3.
A diffusing bar 106 is clamped inside the notch 101; a PCB light bar 105 haying PCB lamps welded thereon is provided between the diffusing bar 106 and the notch 101, and the PCB light bar 105 is secured to the ribs by welding the PCB lamp panel 104 and sleeved with a stopper 8 for protection. The technical solution as described above constitutes a novel light emitting device that may also be used with the light guide bar structure.
The number of the ribs of this lighting umbrella is not limited. The lighting umbrella may include four ribs, six ribs, eight ribs, etc. The lighting umbrella is also not limited to an upright umbrella or roman umbrella in terms of shape. Any equivalent replacements or improvements made without departing from the principle of this structure shall be deemed as falling into the protection scope of the utility model.
