The utility model provides a lamp, including the center seat 1 and a plurality of lamp strip 2 of connecting in center seat 1 that have first installation position, second installation position. In the lamp, the center base 1 comprises a plurality of first installation positions and a plurality of second installation positions, and any one lamp strip 2 can be connected with the center base 1 through one first installation position or one second installation position in a positioning mode.

In this light fixture, the number of light bars 2 includes, but is not limited to, three, four, or six. The specific number of lamps can be set in combination with the structure and dimensions of the central seat 1.

When all the lamp strips 2 are connected in a positioning mode through the first installation positions of the central seat 1, all the lamp strips 2 are arranged around the central seat 1, and the long axis directions of all the lamp strips 2 are located in the same plane. If any one of the light bars 2 is ideally considered as a line, all the light bars 2 are equivalent to a plurality of radial lines which are radially distributed in the same plane by taking the central seat 1 as a midpoint. At this time, if the light emitting surface of the light bar 2 is on the long strip-shaped surface in the long axis direction of the light bar 2, the lamp can provide light to one side or both sides of the reference surface with the surface where all the light bars 2 are located as the reference surface, and the beam angle can reach 180 ° at most. If the light emitting surface of the light bar 2 is located at the end of the light bar 2 in the long axis direction, the lamp can irradiate the periphery of the central base 1 with the central base 1 as a base point, and the beam angle can reach 360 degrees at most.

When all the lamp strips 2 are connected in a positioning mode through the second mounting positions of the center seat 1, the roots of all the lamp strips 2 are located on the same surface of the center seat 1, and the light emitting surfaces of all the lamp strips 2 connected in a positioning mode through the second mounting positions are distributed in an encircling mode. At this time, if the light emitting surfaces of the light bars 2 are positioned at the inner sides of the surrounding directions of all the light bars 2, the lamp can irradiate a certain object positioned at the inner sides of the surrounding directions and enable the beam angle to reach 360 degrees at most; if the light emitting surface of the light bar 2 is positioned at the outer side of the surrounding direction of all the light bars 2, the lamp can irradiate towards the outer side of the surrounding direction and the beam angle can reach 360 degrees at most.

In summary, in the lamp, the illumination range of all the light bars 2 installed through the first installation position mainly depends on the position of the light emitting surface of the light bars 2, and the illumination range of all the light bars 2 installed through the second installation position mainly depends on the relative position relationship of the light emitting surfaces of all the light bars 2. The light bar 2 can be selectively connected to one of the first mounting position and the second mounting position, so that different mounting modes between the light bar 2 and the central seat 1 can be formed. For the lamp strips 2 of the same model, when the plurality of lamp strips 2 are positioned and connected to the central seat 1 in different mounting modes, the lamp can adjust the light-emitting position and the light-emitting angle, and different lighting requirements of different occasions are met. For example, when the lamp is used as a ceiling lamp and the light emitting surface of the light bar 2 is positioned on the side of the long axis direction, the lamp with the light bar 2 connected to the first mounting position can meet the use requirement; when the lamp is used as a compact lamp and the light emitting surface of the lamp strip 2 is positioned on the side surface in the long axis direction, the lamp strip 2 is connected to the lamp at the second mounting position, so that the use requirement can be met.

The following provides a further description of the lamp provided by the present invention with reference to the accompanying drawings and the embodiments.

On the basis of the above embodiments, in the lamp, any one light bar 2 can be hinged to the first mounting position. At this moment, the light bar 2 uses the long axis direction of the light bar as a rotating shaft, and the root of the light bar 2 is rotatably connected to the first installation position.

For example, if the central seat 1 and any one of the light bars 2 are both plate-shaped structures, for example, the central seat 1 is a rectangular plate or a circular plate, and any one of the light bars 2 is an elongated plate, and the light emitting surface is an elongated plate surface, all the light bars 2 may be in the same plane as the central seat 1, and the shape thereof is similar to a snowflake shape, and can provide illumination to the same side or the opposite side of the plane. Of course, when the light bar 2 is rotated around the long axis direction of any one of the light bars 2, the plane where the light bar 2 is located intersects with the plane where the central base 1 is located, and specifically, the relative position relationship between any one of the fan blades and the base in the fan in the prior art can be referred to.

As to how to specifically realize the above-mentioned connection of lamp strip 2 and first installation position, can combine the structural shape setting of the structural shape of first installation position and the root of lamp strip 2. For example, the root of the light bar 2 can be connected with the first mounting position shaft hole to realize the rotation fit of the two, at this time, one is in a spherical or rotary shaft-like shape, and the other is in a hole shape matched with the first mounting position shaft hole.

In order to simplify the structure of the center base 1, in the luminaire, all the first mounting locations and all the second mounting locations may be respectively disposed on different surfaces of the center base 1, for example, all the first mounting locations are on the first surface of the center base 1, and all the second mounting locations are on the second surface of the center base 1. The first surface surrounds the center base 1, for example, when the center base 1 is a disc-shaped structure, the first surface is a circumferential surface of the center base 1; when the central seat 1 is cubic, the first surface is a folding surface connected end to end. Obviously, when the central seat 1 is in a disc shape, all the second mounting positions are located on the axial end face of the central seat 1; when the central base 1 is cubic, all the second mounting positions are adjacent to the folding surfaces.

In the above structure, the first mounting position and the second mounting position of the center seat 1 are distributed on different surfaces of the center seat 1, so that the local surface structure of the center seat 1 can be prevented from being complicated.

In particular, when the first surface and the second surface are adjacent and the first mounting position and the second mounting position are both slot structures, the first mounting position on the first surface can be adjacent to and communicated with the second mounting position on the second surface. At this time, the first installation position and the second installation position can be connected to form a corner installation groove 5. Taking two adjacent surfaces of a cube as an example, the corner mounting groove 5 is located at a ridge of the two adjacent surfaces, one side of the ridge is a first mounting position, and the other side of the ridge is a second mounting position.

Based on the structure, the lamp strip 2 of the lamp is hinged to the corner mounting groove 5, and the rotating shaft is in the groove width direction of the corner mounting groove 5, so that the lamp strip 2 can be rapidly switched to the second mounting position from the first mounting position in a rotating mode.

A specific example is provided below for explaining how to realize the rotation of the light bar 2 of the lamp in the first installation position by taking the long axis direction of the light bar 2 as an axis, and the rotation of the light bar 2 along the groove channel of the corner installation groove 5 by taking the groove width direction of the corner installation groove 5 as an axis.

In this specific example, a corner joint 3 is provided between any one of the light bars 2 and the corner mounting groove 5.

The periphery of corner joint 3 is equipped with the location axle, and this location axle inserts and is fixed a position in corner mounting groove 5, including and not being limited to the pivot adorn in the locating hole in corner mounting groove 5 or slide along the constant head tank in the corner mounting groove 5. Because the location axle of corner joint 3 is when installing in corner mounting groove 5, the axial of location axle is on a parallel with the groove width direction of corner mounting groove 5, consequently, no matter the location axle dead axle rotates in aforementioned locating hole, still slides along aforementioned constant head tank, and this corner joint 3 all can realize rotating along the channel direction of corner mounting groove 5, and then the realization is installed in the lamp strip 2 of this corner joint 3 and is rotated along the channel direction of corner mounting groove 5.

A hinge hole 32 which is in running fit with the root shaft hole of the light bar 2 is formed in the corner joint 3; wherein, the lamp strip pivot that the root of lamp strip 2 can set up. Under the cooperation of the hinge hole 32 of the corner joint 3 and the shaft hole of the lamp strip rotating shaft of the lamp strip 2, no matter the corner joint 3 is in any position of the corner mounting groove 5, the lamp strip 2 can realize fixed-axis rotation relative to the corner joint 3. Particularly, when the corner joint 3 is located at the first mounting position in the corner mounting groove 5, the fixed axis rotation process is a process in which the light bar 2 rotates in the first mounting position with the long axis direction of the light bar 2 as the axis.

Considering that the lamp strip 2 needs to be positioned when rotating to a certain angle, so as to ensure that the lamp strip 2 can be maintained at a specific angle for a long time, and meet the lighting requirements of users, therefore, for the lamp strip rotating shaft and the hinge hole 32, the interference fit between the lamp strip rotating shaft and the hinge hole can be utilized to meet two connection requirements of rotation and positioning, and the polygonal column structure of the lamp strip rotating shaft and the cylindrical inner wall of the hinge hole 32 can also be utilized to meet two connection requirements of rotation and positioning.

Obviously, for the positioning of the rotary joint in the corner mounting groove 5, the interference fit can be utilized to meet the requirements of both positioning and rotation.

In the above embodiment, the rotation angle of the rotation angle mounting groove 5 is preferably set to 90 °. One then a plurality of corner mounting grooves 5 have unified corner scope and be favorable to the design and the batch processing of spare part, two then based on the practical application of this lamps and lanterns, lamp strip 2 rotates 0 ~ 90 in corner mounting groove 5 and can satisfy the illumination scope under most occasions, consequently, compare in the corner of wider range, 0 ~ 90 corner scope is favorable to the shape and the size of reasonable control center seat 1, guarantees the product quality and the aesthetic property of this lamps and lanterns in installation and use.

All the lamp strips 2 in the first mounting position are uniformly arranged on the periphery of the central seat 1 in a surrounding manner, for example, 3 lamp strips 2 are arranged on the periphery of the disc-shaped central seat 1 at equal intervals, and the included angle between every two adjacent lamp strips is 120 degrees.

As for the lamp strip 2 of the lamp, the lamp strip can comprise a lamp shell and LED lamp beads arranged in the lamp shell. A plurality of LED lamp beads can be arranged in one lamp shell, and all the LED lamp beads can be closely arranged along the same positioning plate body in the same lamp shell, so that all the LED lamp beads form an LED lamp panel in the same lamp shell.

The luminous efficiency of the LED lamp panel can be not lower than 115lm/W, so that the illumination intensity of the LED lamp panel meets the requirement of a general light source.

In the lamp strip 2, only one side surface of the lamp shell is provided. For example, the lamp housing is assembled using a light emitting cover plate and, for example, a light emitting base plate. The light-emitting cover plate is a light-transmitting plate, the light-emitting bottom plate is a plate body without light transmittance, the light-emitting bottom plate can ensure the lighting effect of the LED lamp beads, and the light-emitting bottom plate can be used as an auxiliary structure for heat dissipation of the LED lamp beads.

Exemplarily, the light-emitting bottom plate is provided with a heat dissipation sheet for conducting heat outwards through the aluminum substrate during operation of the LED lamp bead.

In addition, in the lamp housing, the edge of the light-emitting cover plate and the edge of the light-emitting bottom plate can be respectively provided with a buckle for realizing the buckle connection of the light-emitting cover plate and the light-emitting bottom plate when the light-emitting cover plate and the light-emitting bottom plate are folded. The light-emitting cover plate can be formed by pressing a light-transmitting acrylic plate, and light of the LED lamp beads can be diffused out.

Similarly, the center base 1 may also be formed in a housing shape with a cavity therein in a manner that a plurality of parts are assembled, for example, the center base 1 includes a center base bottom cover and a center base top cover which are fastened to each other.

Therefore, the lamp housing assembled by the light-emitting cover plate and the light-emitting base plate has a relatively shared light-transmitting surface and a relatively shared backlight surface. Based on the structure, in the lamp, the backlight surfaces of all the light bars 2 in all the second installation positions are close to each other. In short, the distance between all the second mounting positions of the center base 1 is close to the radial dimension of any one light bar 2. Therefore, when all the light bars 2 are in the second mounting positions in a one-to-one correspondence manner, all the light bars 2 can be closed together without gaps or with small gaps, so that a structural shape similar to a compact LED bulb is formed, and the light emitting surfaces of two adjacent light bars 2 can be spliced more closely.

In addition, the lamp is provided with a power supply inside the central seat 1, and a power supply lead is arranged between the power supply and any one of the lamp strips 2. It can be seen that, for the center base 1, the surface thereof is provided with a plurality of first mounting holes for the power supply wires to pass through; correspondingly, for any one light bar 2, the root part thereof is provided with a second mounting hole for the power lead to pass through.

When all the light bars 2 are powered by the same power supply, the lamp can further comprise a lamp head 4 connected to the central base 1, and the lamp head 4 is used for being connected with a lamp holder in a field, so that an external power supply in the field is introduced into the power supply of the central base 1.

Of course, in addition to the above structure in which the same power supply supplies electric energy to all the light bars 2, the lamp may further include an independent power supply inside any one of the light bars 2, so that a power supply wire does not need to be additionally disposed between the central seat 1 and any one of the light bars 2, and the installation position of the light bars 2 relative to the central seat 1 is convenient to adjust.

No matter adopt same power to whole lamp strip 2 power supplies, still by the independent power supply of each lamp strip 2, all can carry out independent regulation and independent control to the illuminating effect of arbitrary lamp strip 2. The independent adjustment corresponds to the influence of the relative position of the light bar 2 and the center base 1 on the lighting effect, and the independent control corresponds to the lighting effect of the single light bar 2 under different control programs of the power supply.

To sum up, the utility model provides a lamp can satisfy the requirements of the luminous position and the luminous angle of different conditions through adjusting the angle of lamp strip 2 relative to center seat 1, for example can be under the operating condition that the beam angle is 180 degrees, provide great illumination scope to the external world; the lighting effect of avoiding the glare of the eyes can be provided for the outside under the working condition that the beam angle is 360 degrees; it is also possible to adjust only the installation angle and the installation position of a part of the light bars 2 relative to the central base 1, thereby providing a functional or decorative lighting effect to the outside in a targeted manner.
