Abstract

An illuminance configuring illumination system for performing light adjustment from at least one light assembly in accordance with a determined illuminance range comprises: the light assembly; a control module, provided with a set of preset light distribution curve data; a distance measuring module, configured to correspondingly measure a light distance of the light assembly, thereby obtaining a light adjustment reference information; and an illuminance measuring module, configured to detect the illuminance environmental variation in the surrounding of the light assembly, thereby obtaining a compensation reference information, wherein the control module performs illuminance adjustment on the light assembly by referring to the set of preset illuminance range according to the light adjustment reference information and the compensation reference information.

Claims

1. An illuminance configuring illumination system for adjusting light from at least one light assembly in accordance with a determined illuminance range, comprising:

the light assembly;

a control module, provided with a set of preset light distribution curve data which is a set of luminous intensity distribution data in relation to an light distribution direction and a light distance of the light assembly;

a distance measuring module, configured to correspondingly measure a light distance from the light assembly to a reference object, which is located in a preset light distribution direction, illuminated by the light assembly, thereby obtaining an illuminance adjusting reference information; and

an illuminance measuring module, configured to detect an environmental illuminance variation existing in the surrounding of the light assembly, thereby obtaining a compensation reference information,

wherein the control module performs illuminance adjustment on the light assembly based on the set of light distribution curve data by referring to the illuminance range, the illuminance adjustment reference information and the compensation reference information.

2. The illuminance configuring illumination system as claimed in claim 1, wherein the illuminance measuring module includes a light detector, configured to correspondingly detect the environmental illuminance variation in a non-light-distribution direction of the light assembly.

3. The illuminance configuring illumination system as claimed in claim 1, wherein the illuminance measuring module includes a plurality of light detectors, configured to correspondingly detect the environmental illuminance variations existing in a plurality of directions including a non-light-distribution direction and a light distribution direction.

4. The illuminance configuring illumination system as claimed in claim 1, further comprising a setting module, coupled with the control module for a user to configure the illuminance range.

5. The illuminance configuring illumination system as claimed in claim 4, wherein the setting module includes a power switch, coupled with the control module through an alternating current power circuit.

6. The illuminance configuring illumination system as claimed in claim 1, wherein the illuminance measuring module includes a light sensor element and a light collector element disposed corresponding to the light sensor element, by which the light sensor element is provided to correspondingly detect the environmental illuminance variation existing in the surrounding of the light assembly through the light collector element.

7. An illuminance configuring illumination method for adjusting light from at least one light assembly in accordance with a determined illuminance range, comprising:

(a) establishing a set of light distribution curve data which is a set of luminous intensity distribution data in relation to an light distribution direction of the light assembly and a light distance of the light assembly;

(b) measuring a light distance from the light assembly to a reference object, which is located in a preset light distribution direction, illuminated by the light assembly, thereby obtaining an illuminance adjusting reference information;

(c) detecting the environmental illuminance variation existing in the surrounding of the light assembly, thereby obtaining a compensation reference information; and

(d) performing illuminance adjustment on the light assembly based on the set of light distribution curve data by referring to the configured illuminance range, the illuminance adjustment reference information and the compensation reference information.

8. The illuminance configuring illumination method as claimed in claim 7, wherein in step (c), the detection, which detects the environmental illuminance variation existing in the surrounding of the light assembly, is performed within a preset short time period during which the light assembly is turned off and after which the light assembly is turned on.

9. The illuminance configuring illumination method as claimed in claim 7, wherein in step (d), the illuminance adjustment is performed by compensating and adjusting the illuminance on the light assembly when there exist any alteration in connection to the determined illuminance range, the illuminance adjustment reference information, and the compensation reference information or when there exist any alteration that exceed a preset range of alteration.

10. The illuminance configuring illumination method as claimed in claim 7, wherein in step (d), the illuminance adjustment is performed by gradually adjusting illuminance on the light assembly according to the extent of the alteration.

11. The illuminance configuring illumination method as claimed in claim 7, further comprising a step of configuring an illuminance range.

12. The illuminance configuring illumination method as claimed in claim 7, wherein in steps (b) and (c), the measurement of the light distance and/or the detection of the environmental illuminance variation for all the light assembly are performed synchronously by following the same alternating current power cycle of a common alternating current circuit.

13. The illuminance configuring illumination method as claimed in claim 11, wherein the step of configuring the illuminance range is synchronously performed by following the same alternating current power cycle of a common alternating current circuit.

14. The illuminance configuring illumination method as claimed in claim 7, wherein in step (c), the environmental illuminance includes the environmental illuminance under the condition that the light assembly is turned on, and wherein in step (d), the illuminance adjustment is performed on a selected light assembly which is the corresponding light assembly that, when the corresponding light assembly is turned on, the illuminance of the environmental illuminance fails to fall within the configured illuminance range.
