The embodiment of the invention discloses a manufacturing method for an LED array device. The manufacturing method is characterized by obtaining an expectation color coordinate of emergent light of the LED array device; obtaining the color coordinate mean values of n LED groups so as to make the expectation color coordinate located in an area defined by a connection line of the color coordinate mean value of the n LED groups; obtaining the total number of needed LEDs; obtaining the number of needed LEDs in each group so as to make a color coordinate of mixed light of m<1> LEDs, color coordinates of which are (x<1>, y<1>,...m LEDs, color coordinates of which are (x, y),...and m LEDs, color coordinates of which are (x, y) be the expectation color coordinate, wherein m<1>+...m+...m=m<0>. LEDs of a needed number of each group are obtained in a color gamut of each LED group and arrayed into an LED array device. The manufacturing method for the LED array device makes the difference between the color of the emergent light and the color of a preset color coordinate not easy to identify and is an LED-array manufacturing method which is lower in cost.
Description
technical field [0001] The present invention relates to the technical field of lighting and display, and in particular, to a manufacturing method of an LED array device. Background technique [0002] LED has the advantages of long life, high luminous efficiency, low radiation and low power consumption, so LED is gradually applied to various fields such as lighting and projection display. For example, in the prior art, LED arrays are often used as light sources for light source systems such as stage lights. In the current LED production process, even for LEDs produced in the same batch, the color coordinates of different LEDs are quite different, and the assembly of LED arrays in the prior art is to randomly select several LEDs in the same batch. Therefore, the color coordinates of the outgoing light of the assembled LED array are often different from the color coordinates of the outgoing light of the predetermined LED array. In addition, the color coordinates of different L...
