Abstract

The invention relates to a light-emitting diode module with good color blending effect, wherein, plural eccentrically packaged light emitting diode packaging bodies arranged in a polygonal shape are installed on the substrate, each eccentrically packaged light emitting diode packaging body includes a base, a light-emitting diode grain biased at side of a centre point of the base, the light sourcedivergent by the equal eccentric packaged light emitting diode packaging body is an non-symmetric light source and declines to a specific direction, therefore the light source can be focused to achieve the purpose of color blending.

Description

technical field [0001] The invention relates to a light emitting diode module, in particular to a light emitting diode module which uses an asymmetrical light source to mix colors into white light. Background technique [0002] Light-emitting diodes (LEDs) are generally considered to be one of the promising light sources due to their advantages of high color saturation, no mercury, long life, and power saving, and their applications are quite wide, such as mobile phones, automotive lighting, and large outdoor displays And other products, can use light-emitting diodes as the main light source. In addition, when light-emitting diodes are used in display light sources or backlight modules, because of their bright colors and high color reproduction, light-emitting diodes are considered to be the most potential products to replace cold cathode ray tube (CCFL) backlights. [0003] figure 1 and figure 2 is a schematic diagram of a traditional cannonball-type light emitting diod...
