The LED chip is mounted in the recess, and a first electrode and a second electrode of the LED chip are electrically connected to the first electrode plate and the second electrode plate, respectively. The Zener diode is embedded in the housing, and a second electrode and a first electrode of the Zener diode is electrically connected to the first electrode plate and the second electrode plate, respectively. The Zener diode of the present invention is embedded in the housing, so that it can prevent from affecting the luminous flux of the LED chip.

Abstract: The present invention discloses a lightbar module for use in a backlight device. The lightbar module includes a plurality of light source units. The light source unit includes at least one first light-emitting diode (LED) with a first color bin in a first wavelength range and at least one second LED with a second color bin in a second wavelength range. A color bin created by the mixed light of the light emitted by the first LED and the light emitted by the second LED after the mixed light passes through an optical glass element being the same as a color bin of the light emitted by an LED with a middle color bin in the first wavelength range after the light passes through the optical glass element, or being the same as a color bin of the light emitted by an LED with the middle color bin in the second wavelength range after the light passes through the optical glass element. The present invention can effectively increase a utilization rates of LEDs will and the cost will decrease effectively.

Abstract: The present invention provides a backlight module and an optical component thereof. The optical component comprises a substrate, a fluorescent layer, and a microstructure. The substrate has a first surface and a second surface. The fluorescent layer is applied on the first surface of the substrate, and the microstructure is formed on the second surface of the substrate. The fluorescent layer and the microstructure are set on two side of the substrate, respectively, so that at least one incident beam is optically refracted or scattered by the microstructure to uniformly penetrate through the microstructure and the substrate. Thus, a blue backlight which penetrate through the fluorescent layer and a yellow backlight which is excited from the fluorescent layer are mixed for ensuring the backlight module to provide a white backlight with uniform brightness and high brilliance.

Abstract: The present invention provides a backlight module and a display apparatus. The backlight module comprises a light guide plate, a base, a first light emitting diode and a second light emitting diode. The base is disposed at one side of the light guide plate. The first light emitting diode is disposed on a first arrangement surface of the base. The second light emitting diode is disposed on the second arrangement surface of the base. The distance between the first light emitting diode and the bottom surface is longer than the distance between the second light emitting diode and the bottom surface. The present invention can improve color shifting defect and coupling effect of the light emitting diodes.
