Abstract

The invention provides an LED illuminance adjustment method, and relates to the field of LED illumination. The LED illuminance adjustment method includes the steps that firstly, LEDs are uniformly distributed and arranged, the number of LEDs is set as N, and the needed illuminance radio in a unit area S is set as P; secondly, according to the needed illuminance radio P, the number N*P of the LEDs which are uniformly distributed is selected, and the N*P LEDs serve as a group; thirdly, according to N*P LED groups, the distribution and arrangement density of the LEDs in the unit area S is determined. The LEDs are divided into groups to be controlled, and the LED groups are uniformly distributed in space, so working time of a single LED can be reduced, and the service life of an element and device can be prolonged; the grouping method is a density grouping method, grouping of LED arrays is completed through selection of the number of the LEDs in the unit area via the method, thus constancy of overall illuminance is guaranteed because the numbers of the LEDs in the groups are the same, and because of uniform distribution of the LEDs, uniformity of overall illuminance is guaranteed .

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a method for adjusting LED illuminance. Background technique [0002] LED lighting is a new type of semiconductor lighting technology. Compared with traditional lighting technologies such as incandescent lamps, LED has the advantages of high luminous efficiency, long service life, good color rendering, safety and reliability. With the enhancement of people's awareness of environmental protection and the advancement of high-power LED technology, in the field of general lighting, LED devices are more and more widely used, such as: landscape lighting, traffic lights, indoor lighting, mine lighting, LED lights for vehicles, etc. . [0003] In many applications, it is often necessary to adjust the illuminance ratio of LEDs to meet different requirements. Generally speaking, the technology currently used to adjust LED illumination mainly involves two aspects: 1 constant current control (C...
