Abstract

A socket for a fairy light has a light-emitting diode (LED) recess (11) being formed in an outer end of the socket and a partition (30A, 30B) being formed on a bottom of the LED recess (11). Any LED (60) can be mounted on the partition (30A, 30B) and protrude out of the socket. Therefore, the LED recess (11) will not limit a lighting range of the LED (60), and the fairy light with small LEDs (60) saves manufacturing costs and energy.

Description

I SOCKET FOR FAIRY LIGHT
2 BACIKGROUND OF THE INVENTION
3 1. Field of the Invention
4 The present invention relates to a socket, especially to a socket for a fairy light that has a light-emitting diode (LED) being mounted in the socket.
6 2. Description of Related Art 7 A fairy light has a light source and a lens and is generally connected in 8 series to form a fairy light assembly. The conventional light source of the fairy 9 light is an incandescent bulb. The lens covers the incandescent bulb and may be colored for aesthetic effects. Light-emitting diodes (LEDs) have advantages over 11 incandescent bulbs including improved electrical efficiency and being more 12 reliable than the incandescent bulb and are replacing incandescent bulbs in many 13 applications. However, with progressing manufacturing skills, LED sizes are 14 getting smaller. A new, small LED has the same brightness as a conventional, big LED and saves manufacturing costs and energy but is smaller than the 16 conventional LED.

17 With reference to Figs. 8and 9, a conventional fairy light (80) has a 18 casing (82), a socket (83) and an LED (81A, 81B). The casing (82) is tubular and 19 has a distal end and a light mount. The light mount is formed in the distal end of the casing (82). The socket (83) corresponds to and is mounted in the light mount 21 of the casing (82) and has an outer end and an LED recess (831). The LED
recess 22 (831) is formed in the outer end of the socket (83). The LED (81 A, 81 B) is 23 mounted in the LED recess (831) of the socket (83). The LED (81A, 81B) may 24 be a small LED (81B) being fully mounted in the recess (831), or a conventional 1 LED (81A) protruding from the recess (831).

2 Although the small LED (81 B) may be mounted in the LED recess (831) 3 of the socket (83), the LED recess (831) was originally designed for the 4 conventional LED (81A). Therefore, the LED recess (831) may limit lighting range of the small LED (81B). However, since many pre-existing technologies 6 are designed around conventional LEDs (81A) and these technologies have 7 manufacturing plants and tools equipped for their production, have passed 8 various safety inspections and have attained safety standards, appearance and 9 sizes of the socket (83) are very expensive to redesign for small LEDs (81B).
To overcome the shortcomings, the present invention provides a socket 11 for a fairy to mitigate or obviate the aforementioned problems.

13 The main objective of the present invention is to provide a socket for a 14 fairy light that reduces manufacturing costs and energy usage. The socket in accordance with the present invention has a light-emitting diode (LED) recess 16 being formed in an outer end of the socket and a partition being formed on a 17 bottom of the LED recess. A small LED being smaller than conventional LEDs 18 can be mounted on the partition and protrude out of the socket. Therefore, the 19 LED recess will not limit a lighting range of the LED, and the fairy light with small LEDs saves manufacturing costs and energy.

21 Other objectives, advantages and novel features of the invention will 22 become more apparent from the following detailed description when taken in 23 conjunction with the accompanying drawings.

14 Fig. 8 is an operational side view in partial section of a socket for a fairy light in accordance with the prior art shown with a conventional LED being 16 mounted in the socket; and 17 Fig. 9 is an operational side view in partial section of the socket in Fig.

18 shown with a small LED being mounted in the socket.

With reference to Figs. 3, 4 and 7, a fairy light comprises a casing (50), a 21 light-emitting diode (LED) (60) and a lens (70). The casing (50) is tubular and 22 has a distal end, an outer surface, a light mount and a latch (52). The light mount 23 is formed in the distal end of the casing (50) and maybe keyed. The latch (52) is 24 formed on the outer surface of the casing (50) adjacent to the light mount.
The 1 LED (60) has two terminals (61, 62). The terminals (61, 62) may comprise a first 2 terminal (61) and a second terminal (62). The lens (70) has a mounting tube (71) 3 and an annular recess (72). The mounting tube (71) protrudes from and 4 communicates with the lens (70) and has and outer surface and a proximal end.
The annular recess (72) is formed around the outer surface of the mounting tube 6 (71) adjacent to the proximal end.

7 With further reference to Figs. 1 and 5, a socket for a fairy light in.

8 accordance with the present invention corresponds to and is mounted in the light 9 mount of the casing (50) and comprises an LED seat (10), a terminal mount (20), a partition (30A, 30B) and an optional holder (40).

11 The LED seat (10) may be keyed to hold the socket securely in the 12 casing (50) and prevent rotation and has an outer end, a bottom, an outer wall and 13 an LED recess (11) and may have an annular protrusion (12) and a latch bar (14).
14 The LED recess (11) is formed in the outer end of the LED seat (10) and has a top edge and a bottom.

16 With further reference to Figs. 4 and 7, the annular protrusion (12) is 17 formed around the top edge of the LED recess (11) and engages the annular 18 recess (72) of the lens (70) to hold the mounting tube (71) of the lens (70) 19 securely in the LED seat (10).

The latch bar (14) is bendable, is formed on the outer wall of the LED
21 seat (10) near the outer end and corresponds to and selectively engages the latch 22 (52) of the casing (50) to ensure the socket is held securely in the casing (50).
23 With further reference to Figs. 2 and 6, the terminal mount (20) is 24 formed on and protrudes from the bottom of the LED seat (10) and has two = 5 1 opposite surfaces, two terminal protrusions (21, 22), two through holes (23) and 2 a first axis (24).

3 The terminal protrusions (21, 22) are formed respectively on the 4 surfaces of the terminal mount (20) adjacent to the bottom of the LED seat (10) and may comprise a first terminal protrusion (21) and a second terminal 6 protrusion (22).

7 The through holes (23) are formed respectively through the terminal 8 mount (20) and between the terminal protrusions (21, 22) and communicate with 9 the LED recess (11) of the LED seat (10).

The first axis (24) is extended through the through holes (23) of the 11 terminal mount (20).

12 The partition (30A, 30B) is formed on and protrudes from the bottom of 13 the LED recess (11) of the LED seat (10) and between the through holes (23) of 14 the terminal mount (20), has a second axis (31A, 31B) and may comprise a wall (30A) or multiple posts (30B).

16 The second axis (31A, 31B) is extended through the partition (30A, 17 30B). The second axis (31A) may be extended through the wall (30A) and may 18 be perpendicular to the first axis (24) of the terminal mount (20). The second axis 19 (31B) may be extended through the posts (30B) and may be perpendicular to the first axis (24) of the terminal mount (20).

21 The holder (40) is formed on the bottom of the LED recess (11) of the 22 LED seat (10) and around the partition (30A) and the through holes (23) and may 23 be multiple arced walls.

24 The socket for the fairy light as described has the following advantages.

1 The terminals (61, 62) of the LED (60) are mounted respectively through the 2 through holes (23) of the terminal mount (20) and are bent to allow the first 3 terminal (61) to abut the first terminal protrusion (21) and the second terminal 4 (62) to abut the second terminal protrusion (22). The LED (60) can be mounted on the partition (30A, 30B) and protrude out of the outer end of the LED seat 6 (10). Therefore, a lighting range of the LED (50) will not be limited by the LED
7 recess (11).

8 Even though numerous characteristics and advantages of the present 9 invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only.
11 Changes may be made in the details, especially in matters of shape, size, and 12 arrangement of parts within the principles of the invention to the full extent 13 indicated by the broad general meaning of the terms in which the appended 14 claims are expressed.
