Please refer to FIG. 1 , FIG. 2 and FIG. 3 , which are schematic views of the appearance of the lighting device according to the first embodiment of the present invention, and a cross-sectional view and an exploded view of the AA of FIG. 1 . The illuminating device 10 includes a light emitting element 20, a body 30, a driving circuit module 40, a tip 50, and an optical element 60. The body 30 includes a first end portion 32, a second end portion 34, and an accommodating space 36. The second end portion 34 and the first end portion 32 are opposed to each other along the axial direction F. The driving circuit module 40 is disposed in the accommodating space 36 for connecting the light emitting element 20 . The tip 50 is detachably coupled to the first end 32 and the optical element 60 is detachably coupled to the second end 34.

The light emitting device 20 can be a Chip On Board (COB) light emitting diode or a Surface Mount Device (SMD) light emitting diode, and is disposed between the body 30 and the optical component 60. The driving circuit module 40 is configured to convert the commercial power input through the terminal 50 into a power source capable of supplying the light-emitting element 20 to emit light. The body 30 is made of a thermally conductive material to facilitate heat dissipation from the illumination device 10. The optical component 60 is selected from the group consisting of a lens, a reflector, and a diffuser. The optical component 60 is configured to receive the light emitted by the light-emitting component 20 and self-illuminate the light emitted by the light-emitting component 20 by means of refraction or reflection. The device is illuminated to the extent that the user is expected to illuminate. In addition, each surface of the optical element 60 may include a plurality of microstructures for increasing the utilization efficiency of the light emitted by the light-emitting element 20 or avoiding the occurrence of uneven spots. If the optical element 60 is a lens, it can be a concentrating lens, an astigmatic lens, an anti-glare lens, and a special shape. lens. The tip 50 includes a joint 52 which is E40, E27, E14, E12, E10, MR16, MR11, GU12 or GU10. In the present embodiment, the light-emitting element 20 is a COB light-emitting diode, the optical element 60 is an anti-glare lens, and the joint 52 is E14, but this embodiment is not intended to limit the present invention. The material of the optical component 60 is selected from the group consisting of polycarbonate (Polycarbonate, PC), polymethylmethacrylate (PMMA), polyetherimide (PEI), and cycloolefin copolymer (Cycloolefin coplymer, COC) group.

In the present embodiment, the first end portion 32 has a first thread 33, the end portion 50 includes a first connecting portion 54, and the first connecting portion 54 has a second thread 56, by the first thread 33 and the second thread 56 The ends 50 are detachably coupled to the body 30. The second end portion 34 has a third thread 35, the optical element 60 includes a second connecting portion 62, and the second connecting portion 62 has a fourth thread 64, which is screwed by the third thread 35 and the fourth thread 64, the optical element 60 is detachably coupled to body 30. .

In the present embodiment, when the third thread 35 and the fourth thread 64 are screwed to each other and the degree of screwing is tighter, the closer the distance L between the optical element 60 and the light-emitting element 20 is (when the third thread 35 and the fourth thread are used When the threads 64 are screwed to each other and locked to the bottom, the distance L between the optical element 60 and the light-emitting element 20 is a minimum value; when the third thread 35 and the fourth thread 64 are screwed together and the degree of screwing is loose, the optical element The further the distance L between 60 and the light-emitting element 20 is.

More specifically, please refer to "4A", "4B" and "4C", which are respectively different implementations of the light-emitting elements and optical elements of the illumination device of the second embodiment of the present invention. schematic diagram. The difference between the second embodiment and the first embodiment is that the optical element 60 of the second embodiment is a concentrating lens, and the other parts are the same. The related drawings are not described here.

In the present embodiment, the light-emitting element 20 can be regarded as a point light source, and the distance L between the light-emitting element 20 and the optical element 60 can be controlled by the degree of screwing between the third thread 35 or the fourth thread 64. When the distance L between the optical element 60 and the light-emitting element 20 is exactly equal to the focal length of the optical element 60, the light is output in parallel (as shown in "Fig. 4A"); the distance L between the optical element 60 and the light-emitting element 20 When the focal length of the optical element 60 is smaller than the focal length of the optical element 60, the light is divergent output (as shown in FIG. 4B); when the distance L between the optical element 60 and the light-emitting element 20 is greater than the focal length of the optical element 60, the light is focused on the output (eg, "Figure 4C"). Since the distance L between the optical element 60 and the light-emitting element 20 is different, the illumination range and the light shape of the illumination device 10 are also different. Therefore, the illumination device 10 is a focus-adjustable illumination device by a design in which the distance L between the light-emitting element 20 and the optical element 60 is adjustable.

In the above embodiment, the optical element 60 is screwed to the second end portion 34, but these embodiments are not intended to limit the creation. For example, the optical component 60 can also be connected to the second end portion 34 in a snap-fit or tight-fit manner, which has the advantages of easy assembly and disassembly, and the like.

In summary, the lighting device of the present invention can eliminate the limitation of the traditional design, make the design more flexible, and can be used according to different user requirements, or when the lighting device only has a tip or an optical component failure. The terminal or optical component can be replaced by itself to achieve the effect of saving source, low cost, convenient and personalized, so that the creation of the creation can be more advanced, more practical and more suitable for the needs of the consumer, and indeed conforms to the creation. For the requirements of the patent application, the patent application is filed according to law.

However, the above is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited by this; therefore, the simple equivalent changes and modifications made by the scope of the patent application and the content of the creation specification are All should remain within the scope of this creation patent.
