Description

Polarized beam angle self-anti-glare LED outdoor directional lighting device

Technical Field

The utility model relates to the field of lighting, especially, relate to an outdoor directional lighting device of LED of polarisation beam angle self anti-dazzle.

Background

The projection lamp is a lamp with the illumination intensity on the appointed illuminated surface higher than that of the surrounding environment, and is mainly used for large-area operation field mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and the like. Thus, almost all large area lighting fixtures used outdoors can be considered as floodlights. The LED projection lamp is mainly applied to exterior wall illumination of single buildings and historical buildings, greening landscape illumination, billboard illumination and other special facilities, and atmosphere illumination of entertainment places such as bars, dance halls and the like.

The outer vertical surface of the building is often provided with an LED wall washing lamp, also called a linear LED projection lamp, and the like. Because the shape of the LED spotlight is strip-shaped, the LED spotlight is also called as an LED line lamp, the technical parameters of the LED line lamp are similar to those of the LED spotlight, and compared with a round structure of the LED spotlight, the heat dissipation device of the strip structure of the LED spotlight wall washing lamp is more beneficial to the treatment. The LED light-projecting wall washing lamp, as the name suggests, enables the lamp light to wash the wall surface like water, is mainly used for building decoration and illumination, and is also used for outlining large buildings. The LED has the characteristics of energy conservation, high luminous efficiency, rich colors, long service life and the like, so that the LED is widely used. The panoramic projection lighting device is very suitable for panoramic projection lighting of inner and outer wall surfaces of government lighting projects, commercial places, subways, overhead overpasses, building outer walls, building landmarks and the like. Landscape building, outdoor square. Painting landscape objects, wall surfaces and showpiece. Can adapt to various indoor and outdoor temperature and humidity environments.

Therefore, the LED projection lamp has a plurality of shapes and types, can be automatically selected from strip shapes, round shapes, square shapes, lengths and sizes, and is suitable for installation and use of buildings with different shapes. The LED projection lamp irradiates light on the wall surface, can be used for architectural decoration and illumination, and can also be used for outlining large buildings. Compared with the traditional lamp, the LED lamp has the advantages of energy conservation, low carbon, long service life, good color rendering property, high response speed and the like. However, the conventional LED light projecting lamp generally has the problems of uneven light projection on the surface of an object to be illuminated, over-concentrated illuminating light beams, easy generation of parasitic light, glare and the like.

Referring to fig. 1, the diagram is an actually measured optical effect diagram after a conventional LED light projector wall washer is installed, the left diagram is an actually shot effect diagram, a black vertex of an angle corresponding to a double-arrow line in the right diagram represents a lamp, an area of a shadow portion between a curve and a vertical line represents light irradiation amount, and in addition, a scale of a horizontal coordinate and a scale of a vertical coordinate in the right diagram are different. Because the lower part of the illuminated wall surface is close to the lamp, and the upper part is far from the lamp, the light rays of the lower part of the illuminated wall are concentrated by the common light distribution, particularly, the light rays are very bright in the range of the double arrow lines, the middle part is weak, the upper part is sharply darkened, and the integral uniformity is very poor. People stand opposite to the irradiated building wall surface, and glaring light is irradiated into eyes of an observer, so that the glaring light is strong, the visual discomfort of the observer is caused, and a great deal of ineffective light loss is generated, so that the illumination utilization rate of the whole lamp is reduced. Therefore, in the process of installing the projection lamp in daily engineering, the inclination angle of the lamp is required to be adjusted manually, the angle difference of each lamp is easily caused, the construction difficulty is increased, and in addition, because the links such as lamp fixing and angle adjustment need to use tools, the whole installation process is long in time consumption, and the installation effect is easily influenced by human factors.

Aiming at the protection of glare of LED lamps, the LED lamps on the market are shielded by an anti-glare plate or an anti-glare cover, and one side of the section bar of the shell needing anti-glare is pulled high, as shown in FIG. 2, the requirement of outdoor lamps on anti-glare protection is met to a certain extent, but more metal materials are inevitably added, and the added materials have very low light reflectivity, so that the light efficiency of the whole lamp is invisibly reduced, the integral weight of the product is increased, the difficulty of production, assembly and packaging is increased, and the production efficiency of the product is relatively low.
