Abstract

An illuminance configuring illumination system for performing light adjustment in accordance with a determined illuminance range includes: at least one 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. 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, comprising:

a light assembly with an illuminance range;

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 a light distribution direction and a control light distance of the light assembly;

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

an illuminance measuring module detecting an environmental illuminance variation existing in surroundings of the light assembly, without a light output of the light assembly, and obtaining a compensation reference information,

wherein the control module performs an illuminance adjustment on the light assembly based on the set of preset light distribution curve data by referring to the illuminance range, the illuminance adjusting 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 correspondingly detecting 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 correspondingly detecting the environmental illuminance variations existing in a plurality of directions including a non-light-distribution direction and the 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 light assembly comprises multiple light assemblies each with the illuminance range;

and wherein the setting module includes a power switch coupled with the control module through an alternating current power circuit, with the setting module configuring the illuminance range synchronously by following a same alternating current power cycle of the alternating current power circuit.

6. The illuminance configuring illumination system as claimed in claim 5, with the illuminance measuring module configured to detect the environmental illuminance variation when the light assembly is turned off and on within a time period that cannot be perceived by a human eye.

7. 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, and wherein the light sensor element correspondingly detects the environmental illuminance variation existing in surroundings of the light assembly through the light collector element.

8. The illuminance configuring illumination system as claimed in claim 1, with the illuminance measuring module configured to detect the environmental illuminance variation when the light assembly is turned off and on within a time period that cannot be perceived by a human eye.

9. An illuminance configuring illumination method for adjusting light, comprising:

providing a light assembly with an illuminance range;

measuring and obtaining a set of light distribution curve data as a set of luminous intensity distribution data in relation to a light distribution direction of the light assembly and a control light distance of the light assembly;

measuring a measured light distance from the light assembly to a reference object located in a preset light distribution direction and illuminated by the light assembly, and obtaining an illuminance adjusting reference information;

detecting an environmental illuminance variation existing in surroundings of the light assembly, without a light output of the light assembly, and obtaining a compensation reference information; and

performing an illuminance adjustment on the light assembly based on the set of light distribution curve data by referring to the illuminance range, the illuminance adjusting reference information and the compensation reference information.

10. The illuminance configuring illumination method as claimed in claim 9, wherein detecting comprises detecting the environmental illuminance variation existing in the surroundings of the light assembly within a preset short time period during which the light assembly is turned off and after which the light assembly is turned on, wherein the preset short time period cannot be perceived by a human eye.

11. The illuminance configuring illumination method as claimed in claim 9, wherein performing comprises compensating and adjusting illuminance on the light assembly when an alteration exists in connection to the illuminance range, the illuminance adjusting reference information, and the compensation reference information or when the alteration exists that exceed a preset range of alterations.

12. The illuminance configuring illumination method as claimed in claim 9, wherein performing comprises gradually adjusting illuminance on the light assembly according to an extent of the alteration.

13. The illuminance configuring illumination method as claimed in claim 9, further comprising configuring the illuminance range.
