Abstract

The invention discloses an illuminating apparatus for improving illumination uniformity. The illuminating apparatus comprises at least two parallel LED lamp tubes. Each LED lamp tube comprises a strip lamp plate with LED illuminating particles arranged on one lateral surface of the same. The LED illuminating particles are distributed on the strip lamp plate in a manner of being dense at two ends and sparse in the middle. The invention further provides a method for improving illumination uniformity. The method includes: initially arranging the LED illuminating particles with equal power and in equal interval layout, subjecting the power of each LED illuminating particle to iterative correction to obtain LED illuminating particles with unequal power and in equal interval layout, and finally enabling the LED illuminating particles with the unequal power and in the equal interval layout to be equivalent to LED illuminating particles with equal power and in unequal interval layout. Therefore, illumination distribution high in uniformity can be obtained a certain distance away from the lamp tubes on which the LED illuminating particles are distributed in the layout mode.

Description

technical field [0001] The invention relates to the field of illumination, in particular to an illumination device and method for improving uniformity of illumination. Background technique [0002] Semiconductor light-emitting diode (LED) is a semiconductor that can convert electrical energy into visible light. It has changed the principle of incandescent lamp tungsten light emission and energy-saving lamp three-based toner light emission, and the use of electric field light emission, the advantages of LED are very obvious, with long life , high light efficiency, no radiation and low power consumption. LED has begun to be widely used in outdoor lighting, landscape lighting, agricultural lighting and other fields. [0003] LED lighting is considered to be one of the most promising fields in the 21st century. While it triggers a lighting revolution, it will also make a major contribution to promoting energy conservation and emission reduction and establishing a conservation-o...
