Technical Field

The utility model belongs to the technical field of the illumination, more specifically the anti-dazzle structure for line lamp that says so relates to.

Background

The existing LED lighting lamp mainly focuses on the brightness and uniformity of the lighting lamp, and along with the fact that the requirements of the current market on LED lighting are higher and higher, the application field is more and more delicate, and the difference of the requirements of different lamps is larger and larger. The lighting effect of the lamp is quite required to meet the requirement of human on the visual effect; the existing lamp has the inevitable problem that because the LED light source belongs to the characteristic of directional light emission, light rays are concentrated, so that the uneven illumination in the irradiation range after light distribution is easily caused, dazzling glare is generated, and people feel uncomfortable.

In the prior art, a lens with a smooth surface and symmetrical circumference is usually used, light emitted by the lens can be only concentrated under a lampshade of the lens, in order to enable the light emitted by a light source to be uniformly emitted to the periphery, a light reflecting cup is generally arranged on a linear lamp, the light reflecting cup has a certain anti-dazzle effect, and in order to further improve the anti-dazzle effect of the lamp, the anti-dazzle cup is provided with the anti-dazzle cover with the anti-dazzle effect.

The problem that above-mentioned patent brought is, lens light source all around can form the even light to diffusion all around earlier after the reflection of anti-dazzle cup, if the diffuse reflection to light on the rethread anti-dazzle cover this moment, the light that can make the final anti-dazzle light cover that jets out becomes scattered indiscriminate light, lead to shining slight greatly reduced to light illumination all around, and the light that does not reflect light cup reflection can only concentrate to shine under anti-dazzle cup, lead to the light intensity in this region too big, make the whole illuminating effect of lamps and lanterns poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides an anti-dazzle structure for line lamp through changing the lens shape, disperses the light earlier, and the collection is gathered together with light to the anti-light cup of rethread to improve the illuminating effect of lamps and lanterns in the time of anti-dazzle.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an anti-dazzle structure for line lamp, includes the lamps and lanterns main part, be provided with anti-light cup and anti-dazzle lens in the lamps and lanterns main part, anti-dazzle lens includes bellied lens piece on transparent bottom plate and the bottom plate, the bottom plate is connected with anti-light cup, and the lens piece passes anti-light cup's bottom of cup and stretches into anti-light cup, be provided with the lamp pearl groove that can place LED lamp pearl on the bottom plate, the bottom surface in lamp pearl groove is smooth curved surface, the surface of lens piece is smooth curved surface, and the bottom of lens piece is the rectangle form, and smooth transition between the two adjacent limits of rectangle.

Furthermore, the rim and the bottom of the reflecting cup are both polygonal with the same shape, the rim is larger than the bottom of the cup, the wall of the reflecting cup is provided with a plurality of reflecting surfaces, and the reflecting surfaces obliquely extend to the bottom of the cup from the rim.

Furthermore, an included angle is formed between the cup mouth of the light reflecting cup and the edge of the cup bottom, and the included angle is 20-30 degrees.

Furthermore, a warning plate is arranged around the cup opening of the reflecting cup, a plurality of light transmission holes are formed in the warning plate, and warning lamps corresponding to the warning plate are arranged on the lamp main body.

Further, a reflective coating is arranged on the reflective surface.

Furthermore, the two opposite sides of the bottom plate are provided with fixing strips, and the bottom of the reflection cup is provided with a clamping hook corresponding to the fixing strips.

Compared with the prior art, the beneficial effects of the utility model are that: light that the bottom surface distributes for smooth curved surface's lamp pearl groove and lens piece through anti-dazzle lens carries out refraction many times to the lamp pearl, the light that sends the lamp pearl disperses earlier, thereby reach anti-dazzle and anti-three light's purpose, and the light after the diffusion jets out light through the reflection of anti-light cup after gathering together, thereby prevent that light from being reduced by the unit illumination intensity after the lens piece refraction, keep the illuminating effect of light promptly when satisfying anti-dazzle.
