Abstract

The invention provides an LED (Light-Emitting Diode) light-emitting element, comprising a packaging shell, an LED light-emitting chip arranged in the packaging shell, and an LED driving chip which is connected with the LED light-emitting chip and is used for driving the LED light-emitting chip to work. The LED driving chip is arranged in the packaging shell; and the LED light-emitting chip is arranged on the LED driving chip. According to the LED light-emitting element, the LED light-emitting chip is arranged on the LED driving chip, so that light emitted by the LED light-emitting chip is difficult to stop by the LED driving chip, and the better light-emitting effect can be achieved. Furthermore, an area of a light-emitting surface of the LED light-emitting element can be reduced by arranging the LED light-emitting chip on the LED driving chip, so that the LED light-emitting element has the advantage of small light-emitting area.

Description

technical field

[0001] The invention relates to a light emitting device, in particular to an LED light emitting element. Background technique

[0002] The English of light-emitting diode is light emitting diode, that is, LED. Due to the advantages of high brightness, long life and high luminous efficiency, LED has been more and more widely used. In actual use, LEDs are often used as large-area indoor and outdoor displays. At this time, for the convenience of use and cost reduction, the LED light-emitting chip and the LED driver chip are often integrated on one board to form an LED light-emitting element with integrated light and driver.

[0003] Please refer to figure 1 , the commonly used LED light-emitting element 100 with integrated lamp and driver is to package the LED light-emitting chip 120 and the LED driver chip 110 together. At this time, both the LED light emitting chip 120 and the LED driving chip 110 are placed at the bottom of the packaging case 130 , and th...
