Description

light stem structure

technical field

The utility model relates to a lamp base structure of a decorative lamp which can be provided with a light emitting diode as a light source in the lamp base.

Background technique

With the progress of the times, the decorative lamps that used small tungsten filament bulbs as their light source in the past have been gradually replaced by light-emitting diodes that have the advantages of power saving, high stability and no high heat, making light-emitting diodes the most The main light source of lamps and lanterns, however, with the advancement of manufacturing technology, the size of light-emitting diodes is getting smaller and smaller, so that compared with the past, the current use of smaller-sized light-emitting diodes can achieve a smaller size than the past. Large LEDs have the same brightness, but also can save manufacturing costs and energy consumption.

Referring to FIG. 7 , a light-emitting diode 81A with a larger size is arranged in a decorative lamp 80 of the prior art, and as shown in FIG. The light-emitting diode 81B, wherein, the decorative lamp 80 is provided with a lamp stem 83 on the top surface of a hollow lamp holder 82, and the top surface of the lamp stem 83 is concavely formed with a groove 831 for placing the aforementioned light-emitting diodes 81A, 81B , but in the past, it was originally designed to provide the lamp stem 83 for installing the larger-sized light-emitting diode 81A. Although the groove 831 on the top surface can also be used to set the current smaller-sized light-emitting diode 81B, it may be due to the lamp stem 83 The depth of the groove 831 is longer than the height of the light-emitting diode 81B, so that the irradiation range of the light-emitting diode 81B is limited by the wall of the groove 831, so that the brightness cannot be fully exerted, and the manufacturer is hindered by people's usage habits and safety inspections, etc. In view of this, it is hoped that the light-emitting diode 81B, which is located in it with a smaller size, can exert its brightness without changing the shape and size design of the original lamp stem 83. Therefore, the lamp stem structure in the prior art has its advantages. room for improvement.

Utility model content

In view of the above-mentioned shortcomings of the prior art, the utility model improves the structure of the lamp pedestal, hoping to solve the problem that the irradiation range of the light emitting diode will be reduced when the groove of the existing lamp pedicle is installed with a small size light emitting diode. Restricted by the wall of the groove, the brightness cannot be fully utilized.

In order to achieve the above-mentioned purpose of the invention, the light base structure of the present invention includes a socket joint, a support portion and a convex seat, wherein:

The top surface of the socket part is concavely formed with a groove;

The supporting part axially protrudes from the bottom surface of the socket part, and a positioning block is respectively provided on two opposite sides of the socket part, and a two-way connection with the groove of the socket part is provided axially through the junction of the two positioning blocks and the supporting part. hole;

The convex seat is arranged in the center of the groove of the socket part, and is located between the two through holes of the lamp base.

The utility model has the advantage that, without changing the shape and size design of the original lamp stem structure, a convex seat is added in the groove, so that the light-emitting diode with a smaller size can be arranged on the convex seat. On the seat, and further protruding from the top surface of the lamp pedestal, avoiding the limitation of the irradiation range by the groove, so even if a decorative lamp equipped with the lamp pedicle of the present utility model uses a small-sized light-emitting diode, the light-emitting diode The brightness of the light-emitting diodes is fully utilized to achieve the purpose of saving manufacturing costs and energy consumption.

Detailed ways

Referring to Figures 1 and 4, the lamp base 1 of the present utility model is arranged on the top surface of a lamp holder 50, and a light-emitting diode 60 and a lamp housing 70 can be arranged on the top surface of the lamp holder 1. The lamp holder 50 It is formed into a hollow tube body, and at least one positioning surface 51 formed as a cut surface is provided on the inner wall near the opening of the top surface (see Fig. 3 for cooperation), and a There is a first fastener 52, the first fastener 52 is provided with a through notch, the bottom surface of the light-emitting diode 60 has two pins 61 protruding, and one side of the lamp housing 70 protrudes a sleeve tube communicating with the inside 71, the junction of the sleeve 71 and the lamp housing 70 is concavely formed with a ring groove 72, and the lamp stem 1 of the present utility model includes a sleeve part 10, a support part 20, a convex seat 30A, 30B and a positioning seat 40;
