Abstract
The invention discloses a luminous environment device for evaluating the projection of a high-luminance large screen with a glaring light source; the structure of the luminous environment device comprises a lighting simulator and a projection system; and the luminous environment device is characterized in that a model is established by the lighting simulator so as to actually display a lighting design scheme in the projection system.
Description
Technical field
The present invention relates to a kind of luminous environment device that is used to estimate the high brightness large screen projection of light source dazzle, be widely used in estimating light source dazzle experiment.
Background technology
The research and development of various high-intensity gas discharge lamps and semiconductor light sources and use make the illumination in city get into efficient, the energy-conservation New Times, but have also brought very important negative effect thereupon, and wherein the glare problem in the illumination is especially outstanding.Especially in the road lighting, the nighttime driving person needs enough illuminations see the various objects on the road clearly, comprises that traffic signals, track, vehicle, pedestrian and other possibly cause dangerous object.Yet excessive or unfavorable illumination will bring dazzle, the comfortable of vision has all been brought extremely with the safety of driving seriously influence.
Therefore, the illuminating engineering of high-quality is not only paid attention in the raising of brightness, also will analyze and control dazzle with scientific methods, reduces its adverse effect as much as possible.Research about dazzle was main with laboratory and two kinds of experimental techniques of field survey person in the past, but the former can not guarantee the accuracy of light source parameters, and it is inconvenient that the latter implements, and it is big to expend goods and materials, and wayward.
Summary of the invention
The objective of the invention is: overcome the deficiency of existing dazzle research, a kind of have better light source parameters accuracy, the lower-cost luminous environment device that is used to estimate the high brightness large screen projection of light source dazzle are provided.
In order to realize the object of the invention, technology below adopting:
Be used to estimate the luminous environment device of the high brightness large screen projection of light source dazzle; Its structure comprises illumination simulator, optical projection system; It is characterized in that: the model through the illumination simulator is set up can show the road Lighting Design scheme really in optical projection system.
Said illumination simulator utilizes computing machine to generate a large amount of rendering images, and the observer can pass through socket, and parameters such as the light efficiency of control light field, area are controlled environment.
Said optical projection system, its core are high-brightness projection machine and associated component, can the super large breadth scene that workstation generates be shown with projection pattern.
Description of drawings
Fig. 1 shows the Organization Chart of the embodiment of the invention.
Embodiment
As shown in Figure 1; A kind of luminous environment device that is used to estimate the high brightness large screen projection of light source dazzle; Its structure comprises illumination simulator, optical projection system, it is characterized in that: set up model through the illumination simulator, can the illumination Design scheme be shown in optical projection system really.
Said illumination simulator utilizes computing machine to generate a large amount of rendering images, and the observer can control environment through the parameters such as light efficiency, area that socket is controlled light field.
Said optical projection system, its core are high-brightness projection machine and associated component, can the super large breadth 3D scene that workstation generates be shown with projection pattern.
In sum; Be used to estimate the luminous environment device of the high brightness large screen projection of light source dazzle; It is characterized in that true to nature in optical projection system, the showing of real road Lighting Design scheme; Be applied in the evaluation of experimenter to dazzle, can realize experimenter, testee feedback in design phase information, make the experimenter comprehensive, adopt suggestion to the test design scheme; Test does not also receive the restriction of place, time and number of times, can carry out playback, reproduction and repetition to process of the test, can be widely used in estimating light source dazzle experiment.
