Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lampshade radiators, in particular to a lampshade radiator. Background Art
[0002] The existing LED lamps are affected by the internal PN structure. When in use, it is necessary to ensure that the internal temperature is not too high. Excessive temperature will affect its service life. In order to more effectively extend the service life of the LED lamp, it is necessary to add a heat dissipation element to the lampshade to ensure the normal use of the LED lamp. The existing LED lampshade radiator has the following shortcomings when in use. First, some lampshades and radiators adopt a split structure and need to be assembled before use. If the assembly accuracy is not high, effective heat dissipation effect cannot be guaranteed. Second, most of the existing lampshades use heat dissipation fins for passive heat dissipation, and the heat dissipation fins directly affect the heat dissipation area. Most of the existing heat dissipation fins are straight plate-shaped and are linearly arranged on the lampshade for heat dissipation. The heat dissipation area is limited, and the heat dissipation effect can still be further improved. Utility Model Content

[0006] Preferably, a second heat sink fin is disposed between two adjacent first heat sink fins, the second heat sink fin extends from an outer edge of the connector to a center of the heat sink, and the length of the second heat sink fin is smaller than that of the first heat sink fin.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.
[0022] Reference Figure 1-Figure 7 As shown, a lampshade radiator comprises a heat dissipation cover 1 at a central position, a rim 2 at an edge position and a connector 3 for connecting the rim 2 and the heat dissipation cover 1, the backs of the heat dissipation cover 1 and the connector 3 are provided with first heat dissipation fins 8, the heat dissipation cover 1, the connector 3, the rim 2 and the first heat dissipation fins 8 are integrally die-cast, there are a plurality of first heat dissipation fins 8, and the plurality of first heat dissipation fins 8 are evenly distributed circumferentially around the axis of the heat dissipation cover 1, and the first heat dissipation fins 8 extend from the center position of the heat dissipation cover 1 to the outer edge position of the connector 3.
[0023] like Figure 3 and Figure 4 As shown, the heat dissipation cover 1, the connector 3 and the edge 2 are an integrally formed structure. The interior formed by the heat dissipation cover 1, the connector 3 and the edge 2 is the installation space of the LED lamp. There is a perforation 4 in the middle of the heat dissipation cover 1 to facilitate the cable threading of the LED lamp in the later stage. In order to better solve the heat dissipation problem of the LED lamp, Figure 1 As shown, a first heat dissipation fin 8 is integrally formed on the back of the heat dissipation cover 1 and the connector 3, and the first heat dissipation fin 8 is arranged in a circular array around the axis of the heat dissipation cover 1, which can more effectively utilize the back area of the heat dissipation cover 1, and the extension direction of the first heat dissipation fin 8 is from the center position of the heat dissipation cover 1 to the outer position of the connector 3, thereby ensuring that the first heat dissipation fin 8 has a sufficient length.
[0024] Furthermore, a second heat sink fin 9 is provided between two adjacent first heat sink fins 8 . The second heat sink fin 9 extends from the outer edge of the connector 3 to the center of the heat sink 1 . The length of the second heat sink fin 9 is less than that of the first heat sink fin 8 .
[0025] Among them, Figure 1As shown, since the first heat dissipation fins 8 are arranged in a circular array, the central position close to the axis of the heat dissipation cover 1 is relatively dense, and the position close to the connector 3 is relatively loose. The second heat dissipation fins 9 are added, and the second heat dissipation fins 9 extend from the outer position of the connector 3 to the center position of the heat dissipation cover 1, which can effectively fill the loose position of the first heat dissipation fins 8 to ensure the heat dissipation effect. Since the second heat dissipation fins 9 only fill the loosely arranged positions of the first heat dissipation fins 8, the length of the second heat dissipation fins 9 is smaller than the length of the first heat dissipation fins 8. It should be noted that the second heat dissipation fins 9, the heat dissipation cover 1 and the connector 3 are also an integral die-casting entity.
[0026] Furthermore, the tops of the first heat dissipation fins 8 and the second heat dissipation fins 9 both have serrations 801 .
[0027] Among them, Figure 6 and Figure 7 As shown, the tops of the first heat dissipation fins 8 and the second heat dissipation fins 9 have serrations 801 , which can significantly increase the contact area between the first heat dissipation fins 8 and the second heat dissipation fins 9 and the air, thereby increasing the heat dissipation effect.
[0028] Furthermore, the vertical projections of the first heat dissipation fins 8 and the second heat dissipation fins 9 are curved.
[0029] The first heat sink fin 8 and the second heat sink fin 9 are both curved. Compared with the traditional straight heat sink fins, the effective length is longer and the heat dissipation effect is better. The specific shape of the curved shape is not limited, and it can be as follows: Figure 6 The continuous arc segment shape shown may also be a wave shape or other curved shapes, as long as it is a non-straight line.
[0030] Further, such as Figures 1 to 5 As shown, a plurality of bosses 5 are formed on the connector 3 , and fixing holes 6 opening toward the interior of the heat dissipation cover 1 are formed on the bosses 5 .
[0031] Among them, the plurality of bosses 5 with fixing holes 6 can facilitate the installation of the reflective cup 10 later. Figure 5 As shown, the edge 2 of the reflective cup 10 has fixing ears 11 corresponding to the boss 5 one by one. Since threads cannot be formed in the fixing hole 6 during the die-casting process, the fixing hole 6 inside the boss 5 can be used after being threaded by a tapping process. The fixing ears 11 can be locked on the fixing hole 6 by screws to fix the reflective cup 10.
[0032] Further, such as Figure 5 As shown, the bottom of the boss 5 is lower than the bottom of the connector 3 , and a U-shaped groove 7 is formed at the bottom of the boss 5 .
[0033] The U-shaped groove 7 can better limit the position of the fixing ear 11, so that the positioning of the reflective cup 10 is more accurate.
[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
