Abstract: A lighting device includes a control circuit board and a plurality of light-emitting diodes. The light-emitting diodes are electrically connected to the control circuit board and each light light-emitting diode includes at least a red-light chip, a blue-light chip, and a green-light chip. The control circuit board forms a control circuit that includes a band switch. Operation of the band switch allows switching of the light-emitting diodes among emission of light of different preset colors.

Abstract: A light source structure of a backlight module comprises: a bar-shaped light source; and a group of complementary color light emitting diodes mounted at both ends of the bar-shaped light source. The bar-shaped light source is composed of several light emitting diodes having complementary light colors. The luminous intensity of outermost light emitting diodes of the bar-shaped light source is 30 to 70% of average luminous intensity of the other equal color light emitting diodes. The complementary color light emitting diodes have light colors complementary to that of the outermost light emitting diodes of the bar-shaped light source. The luminous intensity of the complementary color light emitting diodes is 10 to 50% of average luminous intensity of the other equal color light emitting diodes of the bar-shaped light source. Consequently, the non-uniform mixing of lights on edges of the backlight module and the producing of bright point can be avoided.
