Abstract

The invention discloses a multifunctional glare source device for simulating a street lamp field environment. A glare source main panel is included, and a plurality of groups of light outlet holes aresymmetrically formed in the glare source main panel; a uniform light source with a corresponding light-emitting area is arranged; an upper baffle, a lower baffle, a left baffle and a right baffle areobliquely installed on the four side edges of the glare source main panel correspondingly. The invention further discloses a multifunctional glare source design method for simulating the street lampfield environment. The arrangement of the lamps completely conforms to the perspective visual angle principle and are more suitable for actual street lamp environment, an instrument for measuring threshold increment (TI) can be calibrated, an instrument for measuring a unified glare value (UGR) and a glare value (GR) can also be calibrated, the application range is wide, the economy is high, a lamp with high uniformity is selected as a light source, a background light source is simulated by utilizing uniform reflected light of a glare source main panel and baffles on the periphery, and the design precision is ensured.

Description

technical field [0001] The invention belongs to the technical field of instrument calibration, relates to a glare source device for simulating street lamp lighting environment, and also relates to a design method for the glare source device for simulating street lamp lighting environment. Background technique [0002] Glare refers to a visual condition in the observer's field of vision, because the existing lighting environment exceeds the adaptability of the observer, which causes the observer's annoyance, discomfort, and even loss of vision. There are two reasons for glare, one is the uneven distribution of road surface brightness, and the other is that the brightness changes too much. Taking the comfort of the human eye as the standard, glare can be divided into two categories: discomfort glare and disability glare. The essence of disability glare is to reduce the visual contrast, and the light emitted by the glare source produces an image on the observer's retina. , whi...
