Description

Stage lamp capable of preventing reflection

Technical Field

The utility model belongs to stage lighting field, concretely relates to stage lamps and lanterns of preventing reflecting.

Background

Stage lights are a particularly important tool in modern stage performances. The conventional stage lamp is composed of a housing, a light source, a pattern plate, an optical lens and a plane lens, which are arranged in the housing, and is shown in fig. 1, wherein arrows indicate the direction of light. The stage lamp is characterized in that light emitted by a light source reaches an optical lens through a pattern disc, and then is emitted through a planar lens, and finally, a visual lighting effect molded by the stage is presented. However, the existing stage lamp has the following problems:

1. light beams emitted by a light source of the stage lamp are refracted by irradiating the planar lens, redundant stray light or light leakage phenomenon can be generated in the process of irradiating the planar lens, the light refracted by the planar lens contains stray light, the light beams are fuzzy, virtual light and other conditions can be generated due to light leakage, and the display effect of the stage lamp is poor.

2. The existing stage lamps are not limited to places such as theatre stages or families, but also used in urban lighting engineering, and increasingly used in outdoor shapes such as roads, landscapes and buildings to enhance the shape effect. Because complicated environment such as outdoor wind-blowing rain drenches can make stage lamp body go up to accumulate dust, fallen leaves or ponding, not only has the potential safety hazard, and the foreign matter can shelter from light output in addition.

Disclosure of Invention

The utility model aims at solving the problem that proposes among the above-mentioned background art, provide a simple structure, waterproof dustproof and anti-reflection light prevents stage lamps and lanterns that reflect light.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a stage lamps and lanterns that prevent reflecting, including the casing with casing matched with front end housing, be provided with light source, pattern dish and optical lens in the casing, still be equipped with spherical lens in the casing, spherical lens set up in optical lens's light-emitting side, spherical lens's surface is equipped with anti-reflection coating layer.

Furthermore, the upper surface and the lower surface of the spherical lens are provided with antireflection coating layers.

Further, the spherical lens is a plano-convex lens.

Furthermore, the antireflection coating layer is a broadband antireflection coating.

Furthermore, the wavelength of the broadband antireflection film is 420-680nm, and the light transmittance T is greater than 98%.

Furthermore, be equipped with the lens hole of stepping down on the front end housing, spherical lens with be equipped with waterproof sealing washer between the front end housing.

Further, the spherical lens extends out of the front end cover through the lens abdicating hole.

Utility model's beneficial effect: the utility model discloses simple structure adopts spherical lens, just spherical lens's surface is equipped with anti-reflection coating film layer, has strengthened spherical lens's light transmissivity, has reduced reflection of light intensity through anti-reflection coating film layer to effectively prevent the stage lamp reflection of light, prevent the pattern virtual light from appearing. And because the outer surface of the spherical lens is spherical, external dust particles are not easy to adhere to and stay in the middle area of the spherical lens to influence the light effect, and the dustproof effect is achieved.

By additionally arranging the waterproof sealing ring between the spherical lens and the front end cover, the stage lamp can reach the IP65 waterproof grade.
