Description

Anti-glare underground lamp for medium-angle light emitting

Technical Field

The utility model relates to the field of outdoor building illumination, in particular to an anti-glare underground lamp for medium-angle light emission.

Background

At present, in the field of outdoor building illumination, the LED underground lamp products on the market are always arranged together with a pedestrian channel due to the fact that the illumination effect of a lamp for illuminating a building is guaranteed, pedestrians can see that the lamp light cannot generate glare effect at night, the market demand of the products is that most of anti-dazzle accessories of the LED underground lamp on the market at present are honeycomb mesh grids with the height of 3-10MM and the side length of 2-4MM or traditional deep-concave anti-dazzle grids, standard methods are adopted for the two methods, namely, the lighting angle of the lamp is narrow (8-15 degrees) or medium (20-45 degrees) or wide (45-90 degrees), manufacturers on the market uniformly adopt the same method, or honeycomb or deep-concave anti-dazzle covers are adopted.

However, the light-emitting angles of different light-emitting angles have different light-emitting angle ranges, and the light-emitting angles of different light-emitting angles have different light-emitting intensity ranges, so that a unified anti-dazzle accessory cannot be adopted, and in order to ensure effective anti-dazzle under the early stage of high light transmittance, the problem needs to be solved from the system structure of the lamp according to the characteristics of each light-emitting angle, thereby realizing precise anti-dazzle, achieving good anti-dazzle effect of different light-emitting angles and higher light transmittance.

The LED underground lamp with the light emitted from the middle angle (20-45 degrees) can not achieve the optimal effect of anti-dazzle and light-emitting rate balance if the anti-dazzle is designed according to the thought of a narrow angle or a wide angle. When the medium-angle LED underground lamp irradiates the wall surface, more luminous flux needs to be projected to the irradiated surface with directivity uniformity, but according to the traditional LED underground lamp, an optical lens of the lamp is projected horizontally upwards, and most of light is projected in the air, so that a dark area is formed at the bottom of the irradiated surface, and the problem of insufficient brightness in the vertical direction of the irradiated surface is solved. In addition, the bidirectional anti-dazzle can cause that some effective light is blocked and cannot irradiate the surface to be shot, and the anti-dazzle treatment is actually carried out only on one side of the observation surface of the pedestrian, so that the unidirectional anti-dazzle has more practical application value.

Therefore, for the range of the light emitting angle of the medium angle (20-45 degrees), there is a need to develop a more effective anti-dazzle scheme for the characteristics of the performance requirement of the product, so as to exceed the general scheme in the industry and the anti-dazzle effect of the general product.
