E26 plug-in bakelite lamp holder

The invention relates to a lamp holder, in particular to an E26 plug-in type bakelite lamp holder which can be more conveniently manufactured, assembled and electrically connected.

According to the bright light, the power of human society can be greatly improved in all aspects. Without the invention of the earliest bright lights (such as light bulbs) and the subsequent improvement of a series of improvements and changes, human progress in all aspects will not So jumping quickly. The appearance of early tungsten filament bulbs was once a great invention of human beings. The principle of tungsten filament bulbs is to heat the tungsten filaments to incandescence by means of electrical current, so that up to 90% of the electrical energy consumed by the tungsten filament bulbs is used for conversion. For heat energy, only 10% is used for illuminating, so tungsten filament bulbs have a high loss of power consumption and low luminous efficiency. In recent years, all walks of life around the world, in the direction of the multiple use of the earth's resources, and the principle of global environmental protection prior to development, all levels of government and the private sector have all made great efforts to implement energy conservation and emission reduction (carbon), especially in lighting. More energy-saving fluorescent bulbs and LED bulbs have been developed to replace traditional tungsten lamps with high power consumption and low luminous efficiency.

In the home environment, a "downlight" is often installed and used. A "panel" is a type of luminaire embedded in a relatively sealed ceiling. It is customary to install a tungsten filament bulb in a recessed lamp for use as a lighting device. Because the environment is relatively sealed, the tungsten filament bulb will have a high heat generation. Therefore, increasing the probability of burning of building materials such as ceilings is relatively dangerous in the home environment. Therefore, in recent years, the recessed light has also been changed to the cold light illumination series, that is, the energy-saving fluorescent light bulb and the LED light bulb are used as the illumination light source in the recessed light.

The structure of the recessed lamp is generally composed of a lamp body and a lamp holder. The lamp body is a shell member, and an accommodating space is formed therein. When assembled, the lamp system is embedded in the through hole formed in the ceiling. The bottom of the lamp body (facing the user) may be a member sealed by a cover surface, or an open type without a cover surface, and the top of the lamp body is open and slightly added. The light beam forms a cavity; the lamp holder is assembled and fixed in the cavity for positioning, and the light source is connected to the upper side, and the light bulb is connected to the bottom, so the light can be illuminated downward by the light bulb, and then Illumination is provided by the downward diffusion of the range covered by the lamp body. Since the lamp holder used in the downlight is generally of the size E26, it is conventionally referred to as an E26 lamp holder.

A conventional lamp holder 10 that is assembled in a downlight is as shown in the first and second figures. The conventional lamp holder 10 is basically composed of an outer casing 11, a metal dome 12 and a metal threaded ring 13. Wherein, the outer casing 11 is formed into a cylindrical shape by a high temperature resistant porcelain material, and the top portion is connected with a conductive line 111 divided into positive and negative two poles by screwing or riveting, and the bottom portion is opened inward; the metal The elastic piece 12 is made of a resilient metal steel, and can be divided into a top plate portion 121 and two elastic plate portions 122 on the two sides of the casing. The top plate portion 121 is fixed to the top surface of the outer casing 11 during assembly. The two elastic plate portions 122 extend obliquely outwardly on opposite sides of the outer casing 11 (as shown in the first figure); the metal threaded ring 13 is from the outer casing 11 The bottom portion is placed in the content, and the metal threaded ring 13 is connected to the conductive wire 111 of one of the poles (negative electrode), which is the conductive wire 111 and the outer casing 11 by screwing or riveting means as described above. And the metal threaded ring 13 is fixed, and the conductive line 111 of the other pole (positive electrode) is also connected by screwing or riveting. A positive electrode conductive tab 112 (as shown in the first figure), the positive electrode conductive tab 112 and exist independently of the open space 13 at the top a threaded opening range of the metal ring.

When assembled into a recessed lamp, the socket 10 is positioned in the top pocket of the lamp body assembled with a recessed lamp, and the elastic plate portion 122 of the two sides of the metal dome 12 is separated from the top of the lamp body. The wall of the slot is snapped to achieve a stable connection between the socket 10 and the top of the lamp body. Then, when the integrated downlight is further mounted on the ceiling, the lamp body of the recessed lamp is embedded upward into the embedded hole formed in the ceiling, and the fixing device is firmly connected between the recessed lamp and the through hole by the snapping means. The function is followed by connecting the conductive wires 111 to the two poles of the power line extending from the mains, so that the switch connected to the wall via the power line can be used for power supply opening and closing control; The bulb is inserted from the bottom of the lamp body, and the threaded joint of the bulb is screwed into the metal threaded ring 13 of the lamp holder 10 to achieve a stable connection. At this time, the threaded joint of the bulb is The top end is in contact with the positive electrode conductive piece 112, and is electrically connected to the conductive wire 111 of the positive electrode, and the threaded portion of the threaded joint of the light bulb is electrically connected to the conductive wire 111 of the negative electrode via the metal threaded ring 13 .

The conventional lamp holder 10 is a long-established product, which is formed into a heat-resistant porcelain material into the outer casing 11, mainly for resisting the high heat generated when a tungsten filament bulb is used, and now the energy-saving fluorescent bulb is changed. When the LED bulb (cold light illumination series) is used as the illumination source in the recessed lamp, the conventional lamp holder 10 is obviously improper due to the following lacking, and should be greatly improved. The missing is:

1. The conventional lamp holder 10 must be connected to the top of the outer casing 11 by means of screwing or riveting to connect the conductive wires 111 divided into positive and negative poles, and then the conductive wires 111 and the mains are installed at the time of installation. The two poles of the extended power line are respectively connected to each other, and such a configuration and the connection method are complicated.

2. The conventional lamp holder 10 is designed such that the top plate portion 121 of the metal dome 12 and the top surface of the outer casing 11 are fixed by screwing or riveting. This configuration and the manner of connection are also complicated.

3. The conventional lamp holder 10 is designed to be connected to the outer casing 11 by the metal threaded ring 13 , and the threaded joint of the bulb is carried by the metal threaded ring 13 . This configuration and the connection manner The same is complicated.
