Description

technical field

[0001] The invention relates to a light emitting device, in particular to a light emitting device with good heat dissipation performance. Background technique

[0002] With the development of the optoelectronic industry, light-emitting elements such as light-emitting diodes (LEDs) have been widely used in display applications of various electronic products.

[0003] Please refer to FIG. 1, a conventional LED light emitting device 1 is provided with an insulating layer 11 on a substrate 10, and a plurality of LED light emitting elements 12 are arranged on the insulating layer 11, and then connected with the set in a wirebonding manner. A metal layer 13 on the insulating layer 11 forms an electrical connection, and finally the LED light-emitting elements 12 are covered with an encapsulation layer 14 to protect the light-emitting elements 12 from being damaged by mechanical, heat, moisture or other factors.

[0004] With the development of high efficiency and h...
