  The present invention relates to a side light emitting LED structure in which dimples having a specific angle and depth are provided, and at least three chips are provided in the dimples, and has a combined light function and an optimal lighting effect. Or side light emitting diodes or similar devices.

  The earliest light emitting diodes are placed in a recess in the frame, and after further steps such as die bonding, wire bonding and packaging, become a single light emitting diode. In general, it is often used for outdoor information signs, traffic signal lamps, and automobile brake lamps.

  In recent years, light-emitting diodes have been applied to backlight modules as light-emitting sources of backlight modules, and light-emitting diodes as such backlight modules mainly emit light and composite light from the three primary color chips inside. Emits light and generates light sources of various colors. In order to increase the illumination effect of the light emitting diode, the appearance of the light emitting diode is provided in a base shape, a dimple is formed on the front side of the base, and a sheet for sealing the dimple is fixed to the top surface of the dimple. At least three chips are embedded therein, each chip is electrically connected to the frame, and the pins of the frame are refracted and arranged on the side surface of the base. Furthermore, after the light emitted from the respective chips in the light emitting diode is combined, the light is condensed through the sealing dimples, and then projected from the top surface of the base to further increase the illumination effect.

  Light emitting diodes used in conventional backlight modules have increased lighting effects, but there is still a difference in preferred lighting conditions, so they need to be improved to meet usage requirements.

  In light of the shortcomings and limitations that exist in practical use, the light emitting diode structure adapted to the conventional backlight module has many years of experience and dedicated to such matters. Finally, I was able to design a new side-emitting LED structure.

  The main object of the present invention is to provide a side light emitting LED structure in which dimples having a specific angle and depth are provided, and at least three chips are provided in the dimples so as to have a combined light function and an optimal lighting effect.

  In order to achieve the above object, the present invention includes a base, a frame, and at least three chips. A dimple is provided on the top of the base, and the angle of the periphery of the dimple is 3 ° to 45 °.

The depth from the upper edge of these chips to the top surface of the dimples is 0.3 mm to It becomes a light emitting diode which is interposed in 3 mm and thus has a combined light function and an optimal illumination effect.

  That is, in the first device of the present application, a dimple is provided on the front side, a base having a dimple peripheral angle of 3 ° to 45 °, and a plurality of dimples fixed to the dimple of the base and provided on the side surface of the base. A frame in which the pins extend, and at least three chips electrically connected to the frame in the dimple and having a depth of 0.3 mm to 3 mm between the upper edge of the chip and the top surface of the dimple; The gist of the invention is to provide a side light emitting LED structure including a sol provided in a dimple of a base and integrally bonding the respective elements.

  The gist of the second device of the present invention is to provide the side light-emitting LED structure according to the first device of the present invention, wherein a plurality of pins from which the frame extends are refracted.

  Further, in the third device of the present application, the side light emitting LED according to the second device of the present application is characterized in that two adjacent pins of the plurality of refractive pins are arranged in the opposite direction on the side surface of the base. The gist is to provide a structure.

  The gist of the fourth device of the present invention is to provide the side light emitting LED structure according to the first device of the present invention, wherein the chip is of a flip chip type.

As described above, according to the present invention, dimples having a specific angle and depth are formed on the top of the base, and at least three chips are provided in the dimple.
