Abstract
A light source illuminance distribution test imaging process device includes a light source holder on which a light source under test and an image pick device are respectively fixed. Opposite the light source under test, a target for calibrating illuminance testing points is fixed. The image pick device is mounted facing to the target for picking illuminance distribution images and inputting the picked signals into a computer to handle by a microcomputer interface. The device has the advantages of rapid distribution test and high accuracy. Detecting is achieved by computer and a set of test standards and function-fitting is laid down accordingly thereby realizing the parameter setting of light source illuminance distribution and realizing displaying of property index data and drawing lines which greatly improves test speed, basically realizes test automation and has high reliability. The light source illuminance distribution test can be accomplished in the test range of 0.1lux-1000lux.
Description
[technical field]: the utility model belongs to light illumination distribution testing technology field, particularly a kind of device that multiple illumination intensity of light source such as point, line, surface are distributed and test fast.
[background technology]: street lamp, auto lamp, with bright pedestrian of its illumination of sending and carriageway, the quality of street lamp, auto lamp light source illumination performance is vital for driving at night safety.Other various illuminating lamps and signal lamps, in order to reach the illumination purpose, test field of illumination each point Illumination Distribution situation is to check the indispensable quality index of light fitting quality, also is that content is tested in the luminous intensity distribution performance danger of national standard or industry standard regulation.
The test job of traditional street lamp, auto lamp and various illuminating lamp and signal lamp luminous intensity distribution performance mainly is to adopt artificial pointwise test method, and this method adopts common illuminometer, artificial reading, complicated operation, efficient is low, and causes personal error and unscientific judgement easily.
For overcoming the inefficient defective of traditional measurement method, it is motionless to have occurred using the illuminometer of being with the data machine to read to be placed on the observation field in recent years, light fixture to be measured is placed on the purpose that reaches the Illumination Distribution condition detection on the rotation platform.This class methods complicated operation and costing an arm and a leg is unfavorable for the light fixture producer and the user luminous intensity distribution performance conventional sense to illuminance of lamp.
[summary of the invention]: the purpose of this utility model is a difficult problem that solves the test of ordinary light source Illumination Distribution, and a kind of light illumination distribution tests imaging method device is provided.This device has the quick and precision advantage of higher of distribution tests.Detect by computer realization, and formulate a cover testing standard and a function match, realize that parameter setting, characteristic index data and figure line that light illumination is distributed show, improved test speed greatly, realized the robotization of test substantially with this.Has higher reliability.
The light illumination distribution tests imaging method device that the utility model provides, comprise the light source holding frame, fix light source to be measured and image collecting device on it respectively, a target that is used to demarcate the illumination test point is fixed on light source to be measured opposite, image collecting device is installed towards target, is used for the collection of Illumination Distribution image and the signal of gathering is handled through microcomputer interface input computing machine.
Advantage and good effect: light illumination distribution tests imaging method device of the present invention compared with prior art has following remarkable advantage:
1. test specification is wide, can finish the mensuration of 0.1lux-1000lux scope inner light source Illumination Distribution.
2. distribution situation that can disposable detection light source illumination.
3. can finish parameter setting, characteristic index data and the figure line demonstration etc. of light illumination distribution tests imaging method device by computing machine.
4. utilize computing machine, the whole system function extensibility is strong.Can finish the automatic test of street lamp, auto lamp and the specific illumination of various illuminating lamps in conjunction with corresponding illuminator standard, binding data storehouse system can finish the storage and the analysis of data information.Development prospect is wide.
[description of drawings]:
Fig. 1 is a light illumination distribution tests imaging method device synoptic diagram.
[embodiment]:
Embodiment 1:
As shown in Figure 1, the light illumination distribution tests imaging method device that the utility model provides, comprise light source holding frame 1, fix light source 2 to be measured and image collecting device 3 on it respectively, a target 4 that is used to demarcate the illumination test point is fixed on light source to be measured opposite, image collecting device is installed towards target, is used for the collection of Illumination Distribution image and the signal of gathering is handled through microcomputer interface 5 input computing machines 6.
In the drawings, the unknown illuminating area of big illumination range light source generation large tracts of land Illumination Distribution to be measured that is fixed on the light source holding frame projects on the target, light through reflection and scattering, can gather image collecting device through after the target to entire target target pattern.Calibration point above the target plays the effect of calibration curve match, only needs the environment parasitic light less during application, and other environmental baselines are not had harsh requirement.Image collecting device performance and auxiliary facility were comparatively ripe already, by USB interface image were imported in the computing machine.Software kit then can be handled the image of gathering, and draws the Illumination Distribution curve, and the result who draws and use artificial hand-held illuminometer point-to-point measurement result to compare.
