Description

Shade structure

The invention belongs to a homogenizing technology of a lampshade, in particular to a lampshade structure with a uniform light effect, thereby improving the uniformity of light emission to enhance the illumination effect.

The main purpose of the luminaire is for lighting. It is mainly composed of a lampshade and a illuminating element. In order to enhance the lighting effect, the illuminating element has been developed from a traditional high-energy, short-life tungsten filament bulb to a low-energy, long-life highlight. Effective gas discharge lamps to increase brightness and light extraction efficiency. In addition to improving the performance of the light-emitting elements, in order to allow the light emitted from the light-emitting elements to be effectively concentrated, the light cover is usually modified to a certain extent, so that the light can be limited to be folded and reflected within a certain range, and the lamp cover can be more capable. The light is evenly scattered in the irradiation area to avoid uneven illumination of the luminaire, which affects the overall illumination effect, resulting in the need to enhance the luminous efficacy of the luminaire or increase the number of luminaires, resulting in intangible energy consumption and increased cost. The problem.

Generally used for lamps such as street lamps, factory lamps or square lamps, because of the need for more efficient lamps, such as simply increasing the wattage of the illuminating components, although it can solve the local illuminance problem, it consumes a lot of energy and will The phenomenon of burning of the illuminating element is caused, so the effect of the lampshade is determined by the advantages and disadvantages of such a luminaire. The lampshade of the conventional lamp is as shown in the first figure, the inner surface of the lampshade (10) is generally a semicircular hemispherical curved surface (15), and the light-emitting element (20) is disposed on the lampshade ( 10) The center of the hemispherical surface (15) allows the light emitted by the light-emitting element (20) to be reflected downward by the hemispherical surface (15), but is limited by the angle of the light emission and the angle of reflection, and will be in the illumination area. The phenomenon that the light distribution is uneven, and the situation of different brightness and darkness is affected, which affects the overall illumination effect.

In other words, if the luminaire can effectively concentrate and evenly distribute the light of the illuminating element, it is believed that it will have additional effects on saving energy and reducing the amount of luminaire used. Therefore, a lampshade is developed to adjust the emission direction of the light-emitting elements to concentrate and evenly distribute the light that cannot be effectively reflected or concentrated through the lampshade, thereby achieving an effect of improving the overall light-emitting efficiency.

In view of this, the inventors still research and improve the structure and lack of existing lamps, and uphold the rich experience in design, development and actual production of the relevant industries for many years, and through continuous efforts and development, they finally provide a function of homogenization. The lampshade structure is designed to overcome the shortcomings of the lampshade of the existing lamp due to uneven light scattering.
