In order to further disclose the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are only for reference and description, and are not intended to limit the creation.

Please refer to the first figure and the second figure, which are respectively an exploded view and a three-dimensional combination diagram of the creation. The present invention provides a lamp cup and lens fixing structure for an LED lamp, comprising a lamp cup 1, an LED light source 2 disposed in the lamp cup 1, a lens 3 disposed on the LED light source 2, and a combination a fixing ring 4 between the lamp cup 1 and the lens 3; wherein:

The lamp cup 1 can be integrally formed of a material having good thermal conductivity, such as a heat dissipating material such as metal or ceramic, which has a cup shape and is hollow inside and has a chamber 10. As shown in the third embodiment, in the embodiment, the lamp cup 1 comprises a base 11 and a plurality of heat dissipation fins 12 disposed on the base 11 , and each of the heat dissipation fins 12 faces the base. The outer side 11 and the upper side extend to surround the base 11 to form the chamber 10.

The LED light source 2 is disposed in the chamber 10 of the lamp cup 1 . More precisely, the LED light source 2 can include a circuit board 20 and at least one light emitting diode 21 disposed on the circuit board 20 ( LED), and the back of the circuit board 20 can be attached to the surface of the base 11 of the lamp cup 1 (as shown in the third figure), so that the heat generated by the light-emitting diode 21 can be transmitted through the base 11 At each of the heat dissipation fins 12 of the lamp cup 1, the heat can be released to help the light emitting diode 21 to dissipate heat.

The lens 3 is made of a light-transmitting material and can be used as a secondary mirror of the LED light source 2, and includes a lens portion 30, a rim 31 extending laterally from the outer edge of the lens portion 30, and a plurality of orientations. A top post 32 erected on the rim 31 in the chamber 10 is formed. As shown in the third figure, the lens portion 30 abuts against the LEDs 21 of the LED light source 2, and can be supported on the circuit board 20 or the susceptor 11 through the top posts 32 (implemented by the present invention) The example is supported on the circuit board 20) for the lens 3 to be housed in the chamber 10 and firmly disposed on the LED light source 2.

Please refer to the fourth figure together. This creation is mainly for the purpose of quick assembly and bonding between the lamp cup 1 and the lens 3 through the fixing ring 4. The fixing ring 4 includes a ring body 40 and a plurality of elastic members 41 disposed on the outer periphery of the ring body 40. Each elastic member 41 further includes a spring arm 410 extending downward from the ring body 40, and a spring formed on the bullet. An abutting portion 411 at the free end of the arm 410, the elastic arm 410 can be a "U" type, and the abutting portion 411 is extended by the end of the elastic arm 410 having a "U"shape; The cup 1 is provided with a snap ring 13 outside the chamber 10. The snap ring 13 has an inner ring edge 130, and the fixing ring 4 is bent inwardly through the elastic arm 410 of each elastic member 41, so that the fixing ring 4 can accommodate It is placed at the port of the chamber 10 of the lamp cup 1 and abuts against the inner rim 130 of the snap ring 13 by the abutting portion 411 of the fixing ring 4, so that the ring 40 is just opposite to the rim of the lens 3. At 31, the lens 3 can be pressed into the chamber 10 of the lamp cup 1 to complete the assembly. Further, a notch 412 can be recessed on the outer side of the abutting portion 411, and the notch 412 can just abut against the lower edge of the inner ring edge 130, so that the fixing ring 4 can be further prevented from falling off, thereby achieving a more stable combination. effect.

Accordingly, since the creation only needs to be inserted into the port of the chamber 10 of the lamp cup 1 through the fixing ring 4, the lens 3 can be pressed into the chamber 10 of the lamp cup 1 to complete the assembly, and thus the assembly is performed. It is quite fast and convenient, and its structure is relatively simple and easy to manufacture.

It is to be noted that, in this embodiment, the snap ring 13 can further be used for fixing the heat dissipation fins 12, and the width of each elastic member 41 of the fixing ring 4 can be smaller than the spacing between the heat dissipation fins 12, The elastic members 41 can be disposed in the distance between the heat dissipation fins 12 .

In addition, as shown in FIG. 5 and FIG. 6 , in another embodiment of the present invention, the lamp cup 1 includes a base 11 and a narrowed width and surrounded by the base 11 . The hollow cup 14 is formed, and the snap ring 13 can also be formed directly outside the hollow cup 14 of the lamp cup 1 by integral molding.

Therefore, the lamp cup and the lens fixing structure of the LED lamp of the present invention can be obtained by the above-mentioned structural composition.

In summary, this creation is a rare new creative product, which can achieve the intended use, but solve the lack of knowledge, and because of its novelty and progress, it fully meets the requirements of new patent applications. To file an application in accordance with the Patent Law, please check and grant the patent in this case to protect the rights of the creator.
