The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

Example 1:

as shown in fig. 1-8, the novel LED lamp of this embodiment includes a housing 1 and an aluminum substrate 4, the housing 1 is integrally formed with pins 2 by injection molding, the aluminum substrate 4 is pre-assembled with fasteners 3, the fasteners 3 are the same as the pins 2 in number and are in one-to-one correspondence, the fasteners 3 are provided with through holes for the pins 2 to pass through, and when the aluminum substrate 4 is placed inside the housing 1 and used for mounting the aluminum substrate 4, the fasteners 3 are frictionally and/or snap-connected to the pins 2.

The cap portion 2a is used for fixedly connecting with the housing 1, and the needle portion 2b is used for inserting into the through hole of the fastener 3.

As shown in fig. 9, the cap 2a has a stepped shaft shape or a circular truncated cone shape, and the end of the cap 2a having a smaller diameter is provided toward the inside of the housing 1.

Both the stepped shaft shape and the circular truncated cone shape may be used to prevent the cap 2a from moving toward the inside of the housing 1.

The material of the pin 2 is conductive metal, and copper can be adopted.

The pins 2 may be used not only for mounting the aluminum substrate 4 but also for conduction.

Preferably, the pin 2 is frictionally connected to the clip 3: as shown in fig. 9, 10 and 11, the fastener 3 includes a bottom plate 3a, the bottom plate 3a is connected with the aluminum substrate 4 in a clamping manner, a through hole 3a1 through which the contact pin 2 can pass freely is formed in the bottom plate 3a, two sides of the through hole 3a1 are respectively provided with a pressing plate 3b, one end of the pressing plate 3b is fixed on the bottom plate 3a, the two pressing plates 3b are both elastic, the two pressing plates 3b are close to each other through self resilience force, and a gap between the two pressing plates 3b in a free state is smaller than the diameter of the contact pin 2.

The aluminum substrate 4 is provided with a through hole with the size matched with that of the bottom plate 3a, and the bottom plate 3a clamps the front surface and the back surface of the aluminum substrate 4 through clamping pins extending from the two ends of the bottom plate and penetrating through the through hole, so that the bottom plate 3a is clamped with the aluminum substrate 4. When with aluminium base board 4 and shell 1 be assembled between/be connected, contact pin 2 passes through-hole 3a1 and extrudes between two clamp plates 3b, two clamp plates 3b are crowded to both sides by contact pin 2 and are opened, contact pin 2 passes the clearance between two clamp plates 3b and continues to move, until aluminium base board 4 assembly is accomplished, two clamp plates 3b extrude on contact pin 2 through the resilience force of self this moment for huge frictional force has been formed between clamp plate 3b and the contact pin 2, thereby prevent contact pin 2 and fastener 3 separation.

Alternatively, the pin 2 is clamped with the fastener 3: on the basis of the preferred scheme, the top of the needle part 2b can be designed with a spherical part with a diameter larger than that of the needle part 2b, and after the spherical part and the needle part 2b integrally penetrate through the pressing plates 3b, the spherical part abuts against one ends of the two pressing plates 3b far away from the bottom plate 3a, so that the inserting needle 2 is clamped with the fastener 3.

Alternatively, pin 2 is frictionally engaged and snapped into catch 3: on the basis of the preferred scheme, a plurality of ratchets arranged along the axial direction of the needle part 2b are arranged on the needle part 2b, so that the contact pin 2 can be inserted between the two pressing plates 3b from one direction and cannot be separated from the other direction, and at the moment, the contact pin 2 and the fastener 3 are in friction connection and clamping connection.
