DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0021] For better explaining the technical solution and the effect of the present invention, the present invention will be further described in detail with the accompanying drawings in the specific embodiments.

[0022] Please refer to FIG. 1. The present invention provides a heating source 100 provided by the first embodiment according to the first solution of the present invention. The heating source 100 is applied in an evaporator of organic light emitting diode (not shown) to heat a heating container in the evaporator. The heating source 100 comprises a heating coil 10 and a protective component 20. The protective component 20 is insulation material. Two ends of the heating coil 10 are connected to a power source (not shown) to receive voltages to generate heat. The protective component 20 is located on the heating coil 10 to restrict a deformation range of the heating coil 10 for restricting contact of two adjacent heater strips 11 in the heating coil 10.

[0023] Specifically, the heat generated after the heating coil 10 receives voltages of the power source is employed to heat the heating container. The expanding with heat and contracting with cold of the heating coil 10 can result in the deformation of the heating container experiencing expanding with heat and contracting with cold. The deformation of the heating container can deliver the deforming force to the heating coil 10. It will result in the deformation of the heating coil 10. The heating source 100 comprises the protective component 20. The protective component 20 is located on the heating coil 10 to restrict a deformation range of the heating coil 10 for restricting contact of two adjacent heater strips 11 in the heating coil 10 for preventing the short circuit the two adjacent heater strips 11. Therefore, the present invention reduces the possibility of the heating coil 10 short circuit and raises the stability of the heating coil 10, and thus, the stability of the evaporator applied with the heating coil can be provided.

[0024] In this embodiment, the heating container is a crucible. The protective component 20 comprises insulation bridges. At least one insulation bridge is located between the two adjacent heater strips 11 in the heating coil 10 for restricting the contact of the two adjacent heater strips 11 in the heating coil 10.

[0025] Specifically, the insulation bridge is an insulation rigid uncut bar. The two ends of the rigid uncut bar are respectively connected to the connected two heater strips 11.

[0026] In this embodiment, material of the insulation bridge is C/Csi composite material. An included angle between the insulation bridge and the two adjacent heater strips 11 is 90 degrees.

[0027] Specifically, as the included angle between the insulation bridge and the two adjacent heater strips 11 is 90 degrees, the support force of the insulation bridge to the heater strips 11 at its two sides is the best. In other word, the result of preventing short circuit of the heater strips 11 at the two sides is the best.

[0028] In other embodiments, material of the insulation bridge can be adjusted on actual demands. The included angle between the insulation bridge and the two adjacent heater strips 11 can be adjusted on actual demands.

[0029] Please refer to FIG. 2. The second embodiment according to the first solution of the present invention provides a heating source 200. The heating source 200 provided by the second embodiment is similar as the heating source 100 provided by the first embodiment. The difference between the two is: in the second embodiment, the protective component 220 further comprises an insulation lining 222. The insulation lining 222 is located between an inner wall of the heating coil 10 and the heating container, and the insulation lining 222 connects to each heater strip in the heating coil 10 to restrict the deformation range of the heating coil 10 for restricting the contact of the two adjacent heater strips 11 in the heating coil 10.

[0030] Specifically, the heat generated after the heating coil 10 receives voltages of the power source is employed to heat the heating container. The expanding with heat and contracting with cold of the heating coil 10 can result in the deformation of the heating container experiencing expanding with heat and contracting with cold. The deformation of the heating container can deliver the deforming force to the heating coil 10. It will result in the deformation of the heating coil 10. The protective component 220 further comprises the insulation lining 222. The insulation lining 222 is located between an inner wall of the heating coil 10 and the heating container, and the insulation lining 222 connects to each heater strip in the heating coil 10 to disperse the deforming force and to restrict the deformation range of the heating coil 10 for restricting the contact of the two adjacent heater strips in the heating coil 10 for preventing the short circuit the two adjacent heater strips 11.Therefore, the present invention reduces the possibility of the heating coil 10 short circuit and raises the stability of the heating coil 10, and thus, the stability of the evaporator applied with the heating coil can be provided.

[0031] Specifically, the insulation lining 222 is an insulation rigid uncut bar.

[0032] Furthermore, the heating source 200 can comprise a plurality of insulation lining 222. The plurality of insulation linings 222 are evenly distributed in an annular space between the inner wall of the heating coil 10 and the heating container. Therefore, the plurality of insulation linings 222 which are distributed as aforementioned has the better result of dispersing the deforming force for restricting the contact of the two adjacent heater strips in the heating coil 10 in a better way and for preventing the short circuit the two adjacent heater strips 11 in a better way.

[0033] In this embodiment, material of the insulation linings 222 is C/Csi composite material. In other embodiments, material of the insulation linings 222 can be adjusted on actual demands.

[0034] Specifically, in other embodiments, the heating source 200 can only comprise the insulation bridge or the insulation linings 222.

In this embodiment, the heating source can be the heating source 200 provided by the second embodiment according to the first solution of the present invention. The structure and the function of the heating source has already described in the aforesaid second embodiment of the first solution in detail. The repeated description is omitted here.

[0036] In other embodiments, the heating source can be other heating source, such as the heating source 100 provided by the first embodiment according to the first solution of the present invention.

[0037] In this embodiment, the heat generated after the heating coil 10 receives voltages of the power source is employed to heat the heating container. The expanding with heat and contracting with cold of the heating coil 10 can result in the deformation of the heating container experiencing expanding with heat and contracting with cold. The deformation of the heating container can deliver the deforming force to the heating coil 10. It will result in the deformation of the heating coil 10. The heating source 100 comprises the protective component 20. The protective component 20 is employed to restrict a deformation range of the heating coil 10 for restricting contact of two adjacent heater strips 11 in the heating coil 10 for preventing the short circuit the two adjacent heater strips 11. Besides, the protective component 220 further comprises the insulation lining 222. The insulation lining 222 is located between an inner wall of the heating coil 10 and the heating container, and the insulation lining 222 connects to each heater strip in the heating coil 10 to disperse the deforming force and to restrict the deformation range of the heating coil 10 for restricting the contact of the two adjacent heater strips in the heating coil 10 for preventing the short circuit the two adjacent heater strips 11.Therefore, the present invention reduces the possibility of the heating coil 10 short circuit and raises the stability of the heating coil 10, and thus, the stability of the evaporator 300 applied with the heating coil can be provided.
