Description

Technical Field

[0001] The utility model relates to the field of lighting brackets, and particularly relates to a multi-color light lighting bracket. Background Art

[0002] Light Emitting Diode (LED) is globally recognized as the most efficient artificial lighting technology at present, with significant advantages such as long lifespan and low energy consumption. In current LED integrated packaging technology, the widely used integrated LED with driver usually takes a single pixel point as the design unit. Each LED contains three light-emitting chips and one driving IC inside, and the driving IC is responsible for controlling the three light-emitting chips to adjust the light-emitting effect of the LED.

[0003] Currently, LED lamp beads with built-in IC chips often adopt a packaging method of arranging the IC chips and light-emitting diodes on the same circuit board surface. However, in small-sized LED lamp beads, the space is very limited. And the size of the IC chip is usually larger than that of the light-emitting diode. When they are placed on the same surface, the IC chip will block some of the light emitted by the light-emitting diode, affecting the light-emitting angle of the LED and reducing the light diffusion and lighting effect.

[0015] (III) Beneficial Effects

[0016] 1. In the present utility model, by arranging the IC chip and the LED light-emitting chip on the front and back sides of the same pad respectively, the light shielding of the LED driving IC volume on the light of the LED light-emitting chip is avoided, so that the light emitted by the LED can be more evenly diffused, improving the light efficiency. At the same time, arranging the chips on the front and back is beneficial to the miniaturization of the lamp beads, without increasing the pad area to place the LED driving IC, and more efficiently utilizing the space.
