Description

Technical Field

[0001] This utility model belongs to the technical field of LED lamp holders, specifically an LED lamp holder with a copper-clad aluminum substrate. Background Technology

[0002] LED lights are lighting devices that emit light using the electroluminescent properties of semiconductor materials. LED lamps consist of LED chips and LED brackets. The LED bracket is a structural component used to fix and support the LED lamp. It is usually made of metal or plastic.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please refer to Figure 1-7 ;

[0025] The substrate of the existing LED bracket is made of stainless steel copper. Although copper has good electrical conductivity and heat dissipation, it is heavier and more expensive than aluminum. Since LED brackets are usually large in scale, using copper as the sole material for substrate 1 would result in a higher price and greater weight for the final product.

[0026] Therefore, this utility model discloses an LED lamp holder with a copper-clad aluminum substrate, including a substrate 1 and a lamp bead frame 2. The substrate 1 is a copper-clad aluminum substrate 1. More specifically, the substrate 1 includes an aluminum layer 101 and a copper layer 102 uniformly coated on the upper and lower surfaces of the aluminum layer 101. In this embodiment, the composite method between the aluminum layer 101 and the copper layer 102 is not limited. For example, the copper layer 102 and the aluminum layer 101 can be formed by pressing together with uneven micropores to increase the tightness between the copper layer 102 and the aluminum layer 101. The total thickness of the substrate 1 ranges from 0.08mm to 0.30mm. In this embodiment, 0.2mm is preferred. Compared with a 0.3mm substrate 1, this saves more material and reduces costs. The substrate 1 layer is 0.08mm thick, which improves mechanical strength. The thickness ratio of aluminum layer 101 to copper layer 102 is 8:1, that is, in this embodiment, the thickness of aluminum layer 101 is 0.16mm and the thickness of copper layer 102 is 0.02mm. In this embodiment, the substrate 1 has a total of 22 rows and 24 columns of pins. The middle row of the substrate 1 is provided with several round holes 3 and rounded rectangular holes 4. The round holes 3 and rounded rectangular holes 4 are spaced apart to improve air circulation, thereby improving heat dissipation performance and reducing the weight of the substrate 1. The LED bead frame also includes a cup body 21 injection molded on the substrate 1. It is worth noting that in this embodiment, the cup body 21 is made of semi-transparent colloid to reduce the light emission of the LED bead.

[0027] Furthermore, the upper and lower sides of the substrate 1 are provided with square notches 5 and V-shaped notches 6. It is worth noting that the square notches 5 and V-shaped notches 6 are spaced apart, and the area of ​​the V-shaped notches 6 is larger than that of the square notches 5. In addition, the upper end of the substrate 1 is provided with circular holes 2 7 and 3 8. The radii of circular holes 2 7 and 3 8 are different, with the radius of circular hole 2 7 being larger than that of circular hole 3 8. Circular hole 2 7 can be used to provide support where load-bearing is required to improve the durability of the overall structure, while circular hole 3 8 can provide better stress dispersion. The lower end of the substrate 1 is provided with circular holes 4 9 and rounded rectangular holes 2 10. Circular holes 4 9 and rounded rectangular holes 2 10 are arranged alternately. The alternating arrangement of circular holes 4 9 and rounded rectangular holes 2 10 can promote airflow and enhance heat dissipation.

[0028] In this embodiment, wherein Figure 6 and Figure 7 These are the front and side views of the LED bead frame 2. The cup body 21 has a cup groove 11. The height of the cup groove 11 ranges from 0.6mm to 0.62mm, the longitudinal angle of the cup groove 11 is 22° to 24° (∠A in the figure), and the transverse angle of the cup groove 11 is 53° to 56° (∠B in the figure). Preferably, the height of the cup groove 11 is 0.6mm, the longitudinal angle of the cup groove 11 is 22°, and the transverse angle of the cup groove 11 is 54°. This ensures the display effect of the LED panel during use and extends the lifespan of the LED.

[0029] To further increase the brightness of the LED lamp holder and prevent the light emitted by the LED beads from escaping, the substrate 1 includes a positive pin 12, a negative pin 13, a negative pin 2 14, and a negative pin 3 15. Three stepped grooves are formed between each pair of the positive pin 12, negative pin 13, negative pin 2 14, and negative pin 3 15. The stepped grooves are filled with a translucent colloid 16 and an opaque colloid 17.

[0030] In the specific accommodation process, during the first accommodation, the translucent colloid 16 is integrally injection molded with the cup body 21. During the second accommodation, the opaque colloid 17 is injection molded, with the opaque colloid 17 positioned above the translucent colloid 16.

[0031] In addition, to further enhance the brightness of the LED light, a reflective coating 18 is provided on the inner wall of the cup body 21; in addition, a polarity mark 19 is provided on the upper end of the side wall of the cup body 21 to facilitate identification by the operator.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
