Description of the invention (7) When a large amount of thermal energy is directly bonded to the cavity as the cavity performance, and the material k is also improved for plastic materials. However, the above-mentioned shapes and structures used to define the present invention should be included in the present invention and the present invention borrows the base of the flip-chip light-emitting diode and the heat-conducting reuse such as metal, ceramic, etc. with high heat dissipation efficiency. It can quickly dissipate heat and effectively improve the heat dissipation of the overall lamp tube. The present invention mainly uses a metal'ceramic or semiconductor material which will be cracked when it is irradiated with violet / ultraviolet light. It is only a preferred embodiment of the present invention. Application scope of the present invention
