Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 and 2, an embodiment of the present invention provides a spiral ceiling lamp, which includes a lamp housing 1 and an LED lamp body 2 disposed in the lamp housing 1, specifically, the LED lamp body 2 includes a circuit board 21 disposed in the lamp housing, a plurality of lamp beads 22 spirally disposed on the circuit board 21, and a spiral lens 23 covering the plurality of lamp beads 22. The light that sends a plurality of lamp pearls 22 is refracted by helical lens 23, enlarges the light scattering angle for the light is to the not equidirectional diffusion, thereby evenly spread to the lamp shade of lamp body 1 on, finally make lamps and lanterns obtain even, bright luminous effect, improved light source utilization ratio and user and used experience.

In the present embodiment, as shown in fig. 3, an outer refraction curved surface 231 is formed on the outer surface of the spiral lens 23. The light that sends lamp pearl 22 by outer refraction curved surface 231 carries out outside refraction, and the not equidirectional light that lamp pearl 22 sent also outwards refracts with the refraction direction of difference after outer refraction curved surface 231 for whole LED lamp body 2 can be to the lamp shade of lamp body 1 on a large scale the light of even diffusion of sending.

In order to better combine the spiral lens 23 and the plurality of beads 22, as shown in fig. 4 and 5, in this embodiment, a spiral accommodating groove 232 for the plurality of beads 22 to be embedded is disposed upward and recessed at the lower end of the spiral lens 23, the spiral accommodating groove 232 extends along the length direction of the spiral lens 23, and an internal refraction curved surface 2321 is formed on the inner wall of the spiral accommodating groove 232. The light rays emitted by the lamp beads 22 are refracted for the first time by the internal refraction curved surface 2321, and the light rays refracted for the first time are diffused in the spiral lens 23 in different directions; when passing through the outer refraction curved surface 231, the light rays refracted by the inner refraction curved surface 2321 are refracted for the second time by the outer refraction curved surface 231, and the light rays refracted for the second time are diffused in a wide range to the periphery of the spiral lens 23 in different directions. Therefore, after the light is refracted twice by the helical lens 23, the whole LED lamp body 2 can emit uniformly diffused light to the lampshade of the lamp housing 1 in a large range.

Since the spiral lens 23 of this embodiment extends spirally from the central point to the periphery of the lamp housing 1, in order to diffuse light rays to the edge of the lamp housing 1 in a wider range, the thickness d between the outer side of the lower opening of the spiral containing groove 232 and the outer side of the outer refractive curved surface 231 is gradually increased from the inner end to the outer end of the spiral lens 23, as shown in fig. 6. From this, by lamp body 1 central point along tip to outer tip in helical lens 23, thickness d thickens gradually, then during light process refracts curved surface 2321 and outer refract curved surface 231, the angle of refraction increases gradually, consequently, does benefit to the light and to lamp body 1 edge wider diffusion, does benefit to the light that LED lamp body 2 sent can more even diffusion to the lamp shade of lamp body 1.

In this embodiment, a longitudinal cross section is formed by longitudinally cutting along the width direction of the spiral lens 23, as shown in fig. 6, a circle a is drawn on the longitudinal cross section by taking the midpoint of the lower opening of the spiral containing groove 232 as a center O and taking the distance between the center O and the highest point of the internal refraction curved surface 2321 as a radius, the radius R of the circle a is 4.0-4.2mm, and the distance b between the center O and the edge of the lower opening of the spiral containing groove 232 is 3.0-3.40 mm. Preferably, the radius R of the circle a is 4.09mm, and the distance b from the center O to the edge of the lower opening of the spiral receiving groove 232 is 3.21 mm.

The curvature range of the inner refraction curved surface 2321 can be further limited by the specific numerical range, and in the numerical range, after passing through the inner refraction curved surface 2321, the light emitted by the lamp bead can be refracted onto the outer refraction curved surface 231 in a large angle and a large range as much as possible, and after being refracted by the outer refraction curved surface 231, the light is uniformly diffused towards the lamp shade of the lamp housing 1, so that a uniform light-emitting effect is obtained.

In this embodiment, several lamp pearl 22 includes RGB lamp pearl and 2835 paster lamp pearl. From this, set up a plurality of RGB lamp pearls and a plurality of 2835 paster lamp pearls simultaneously on circuit board 21 (circuit board 21 is preferred to be aluminium base board) to set up at helical lens 23 inboardly, realized being joined in marriage RGB (red green blue) light source and SMT paster 2835 light source array grading simultaneously by helical lens 23, for the structural design that a lamp pearl was joined in marriage to traditional single optical surface, this embodiment lamp pearl quantity can increase at will and reduce, makes lamps and lanterns adjustment power unrestricted.

As for the combination manner of the spiral lens 23 and the circuit board 21, as shown in fig. 4 and 5, in this embodiment, a circuit board slot 233 is formed on the lower end surface of the spiral lens 23, two side edges of the circuit board 21 are clamped in the circuit board slot 233, as shown in fig. 5, the spiral accommodating slot 232 is formed on the circuit board slot 233, and the circuit board 21 and the circuit board slot 233 are both spiral, so that the plurality of beads 22 spirally distributed on the circuit board 21 are just accommodated in the spiral accommodating slot 232.

In the present embodiment, as shown in fig. 1 and fig. 2, the lamp housing 1 mainly comprises a bottom case 11 and a lamp cover 12 covering the bottom case 11, wherein a plurality of screw holes (230,210) are formed at the edge of the spiral lens 23 and the edge of the circuit board 21, and the spiral lens 23 and the circuit board 21 are mounted in the bottom case 11 by matching a plurality of screws with a plurality of screw holes (230,210).

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
