Description

Technical Field

[0001] This utility model relates to the field of multi-color LED lamp technology, specifically a phosphorless multi-color Chinese ball lamp with uniform light mixing. Background Technology

[0002] The Chinese ball lamp is a street lamp with distinctive Chinese characteristics. It has a bright, majestic and solemn appearance and is suitable for municipal engineering, landscaping lighting projects, and outdoor street lighting projects in power bureaus, development zones, villa areas, squares and other places.

[0003] Currently, the light sources inside Chinese ball lamps are all single-color LEDs. The lamps have internal columns for wires to pass through, maintaining the overall aesthetics of the fixture. To avoid the columns obstructing the light output of the LEDs, they are generally cone-shaped to minimize the space occupied by the end closest to the LED. However, while using multi-color LEDs could provide a richer display effect, it would also result in noticeable uneven light mixing. Therefore, we propose an improved, phosphor-free, multi-color Chinese ball lamp with uniform light mixing. Utility Model Content

[0004] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the background technology, and to provide a phosphorless multi-color Chinese ball lamp with uniform light mixing.

[0005] A phosphorless multi-color Chinese ball lamp with uniform light mixing includes a spherical lamp housing. An LED bead mounting base is provided at the upper end of the spherical lamp housing. A cylinder is installed in the middle of the lower surface of the LED bead mounting base, and a number of multi-color LED beads are distributed in a circular array around the cylinder. The multi-color LED beads include LED beads of four colors: red, yellow, blue, and green. The bottom end of the cylinder extends downward to contact the lower surface of the spherical lamp housing. A second aluminum-plated reflective film layer is attached to the outer surface of the cylinder.

[0006] A further embodiment is that the inner wall of the spherical lamp housing is provided with several light-emitting holes, and a light-emitting plate is embedded in the light-emitting holes. The light-emitting plate is made of transparent material, and a first aluminum-plated reflective film layer is attached to the inner wall of the spherical lamp housing. The first aluminum-plated reflective film layer is hollowed out at the corresponding position of the light-emitting plate.

[0007] A further option is to have a first cavity inside the cylinder.

[0008] A further embodiment is that the spherical lamp housing is provided with a connecting rod, the middle of which is accommodated in the first cavity, and the two ends of the connecting rod pass through the spherical lamp housing and are set as threaded rods, and the base and the top cover are respectively threaded through the threaded rods.

[0009] A further embodiment is that the base is cup-shaped and surrounds the bottom of the spherical lamp housing; the top cover is cap-shaped and surrounds the top of the spherical lamp housing, and the outer surface of the top cover has ribs arranged in a ring array.

[0010] A further option is to mount the bottom of the base onto the lamp post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses multi-color LED beads, which can bring richer display effects. At the same time, this application replaces the conical cylinder of the prior art with a cylinder and attaches a second aluminum-plated reflective film layer to the outer surface of the cylinder, thereby increasing the reflective area and making the light emitted by each primary color LED bead fully mixed, thereby improving the phenomenon of uneven light mixing. Furthermore, a first aluminum-plated reflective film layer is set on the inner wall of the spherical lamp housing, which can ensure that the light emitted by each primary color LED bead is further fully mixed. In addition, a connecting rod is set inside the cylinder. The two ends of the connecting rod penetrate the spherical lamp housing and are respectively threaded to a cup-shaped base and a cap-shaped top cover, making the overall Chinese ball lamp more beautiful. The ribs in the ring array on the outer surface of the top cover increase the surface area of ​​the top cover, thereby improving the heat dissipation capacity of the Chinese ball lamp. And the wire extends through the bottom end of the connecting rod to the threaded groove in the middle of the base, which can ensure that the wire will not be twisted during the assembly of the base and the Chinese ball lamp.

[0016] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figures 1-2 This utility model provides a phosphorless multi-color LED ball lamp with uniform light mixing, comprising a spherical lamp housing 3. An LED bead mounting base 9 is disposed at the upper end of the spherical lamp housing 3. A cylinder 6 is mounted in the middle of the lower surface of the LED bead mounting base 9. A plurality of multi-color LED beads 10 are arranged in a circular array on the lower surface of the LED bead mounting base 9. A first cavity 12 is formed inside the cylinder 6, which allows the wires of the multi-color LED beads 10 to pass through and also helps to reduce the weight of the cylinder 6. In this embodiment, the multi-color LED beads 10 include red, yellow, blue, and green LED beads. The four colors of LED beads are arranged in a circular array around the cylinder 6, and the four colors of LED beads are arranged at radial intervals along the LED bead mounting base 9, so that LED beads of the same color are dispersed as much as possible.

[0020] Furthermore, the bottom end of the cylinder 6 extends downwards to contact the lower surface of the spherical lamp housing 3, and a second aluminum-plated reflective film layer 7 is attached to the outer surface of the cylinder 6. It is understood that the wires corresponding to the multi-color LED beads 10 pass through the first cavity 12 inside the cylinder 6, maintaining the overall aesthetics of the lamp. Moreover, this application replaces the conical cylinder of the prior art with a cylinder 6, and attaches the second aluminum-plated reflective film layer 7 to the outer surface of the cylinder 6, thereby increasing the reflective area of ​​the end of the cylinder 6 near the multi-color LED beads 10, allowing the light emitted by each primary color bead to mix fully, thus improving the uneven light mixing phenomenon.

[0021] Preferably, the inner wall of the spherical lamp housing 3 has several light-emitting holes, and a light-emitting plate 5 is embedded in each light-emitting hole. The light-emitting plate 5 is made of transparent material, allowing light to pass through and preventing rainwater from entering the interior of the spherical lamp housing 3 through the light-emitting holes. A first aluminum-plated reflective film layer 4 is attached to the inner wall of the spherical lamp housing 3, and the first aluminum-plated reflective film layer 4 is perforated at the corresponding position to the light-emitting plate 5. The first aluminum-plated reflective film layer 4 can reflect the light emitted by the multi-primary-color LED beads 10, thereby facilitating further and more thorough mixing of the light emitted by the multi-primary-color LED beads 10; and the perforation at the corresponding position to the light-emitting plate 5 ensures that the first aluminum-plated reflective film layer 4 does not obstruct the fully mixed light from passing through the light-emitting plate 5.

[0022] Optionally, a connecting rod 8 is provided on the spherical lamp housing 3. The middle part of the connecting rod 8 is accommodated in the first cavity 12. Both ends of the connecting rod 8 pass through the spherical lamp housing 3 and are set as threaded rods, which are threadedly connected to the base 2 and the top cover 11 respectively. The base 2 is cup-shaped and surrounds the bottom of the spherical lamp housing 3; the top cover 11 is cap-shaped and surrounds the top of the spherical lamp housing 3. The outer surface of the top cover 11 has a ring array of ribs. The base 2 and the top cover 11 make the overall Chinese-style lamp more aesthetically pleasing; moreover, the ring array of ribs on the outer surface of the top cover 11 increases the surface area of ​​the top cover 11, thereby improving the heat dissipation capacity of the Chinese-style lamp.

[0023] Preferably, the wire extends from the bottom of the connecting rod 8 into the threaded groove in the middle of the base 2. This arrangement ensures that the wire will not be twisted when the base 2 rotates relative to the spherical lamp housing 3 during the assembly of the base 2 and the Chinese ball lamp.

[0024] Preferably, the bottom end of the base 2 is installed on the lamp post 1, and the bottom end of the lamp post 1 is fixed to the ground by anchor bolts, so that the center of the spherical lamp housing 3 is 1.5~2m away from the ground.
