Description

LED lamp holder structure

Technical Field

The utility model relates to a ornament lamp, concretely relates to LED lamp holder structure suitable for as decorating the application lamps and lanterns in festivals such as christmas.

Background

The ornament lamp is as the usefulness of house, city face decoration during the holiday to improve corresponding holiday atmosphere, its application range is comparatively extensive, the utility model discloses a LED lamp holder structure mainly is applied to the ornament lamp of intubate formula (directly insert the lamp for the decoration on the hollow tube with the lamp holder structure promptly), and the lamp holder structure of this type ornament lamp mainly has two kinds of structures in prior art: firstly, directly adopt the glass system lamp body of vacuum state, be provided with the tungsten filament in this glass system lamp body, then at this glass system lamp body below installation insulating plug socket, when plug socket and glass system lamp body carried out fixed mounting, need insert the inside pin that draws out of glass system lamp body respectively corresponding jack in the plug socket, then be connected pin and wire again, can effectively avoid the contact between the pin and short circuit from this, the defect of this kind of lamp holder structure lies in: the pins are slender, so that the jacks arranged on the plug socket are also slender, in addition, the pins also have certain flexibility and are easy to bend, and a certain guide structure needs to be arranged in the plug socket to guide the pins into the jacks, so that a series of problems all put forward higher requirements on the structure of the plug socket, the cost is increased in the development and manufacturing of a die, the assembly of a glass lamp shell and the plug socket is also difficult, particularly, the alignment assembly process of the pins and the jacks is unstable, and the assembly reject ratio is increased; the LED lamp holder structure of the structure directly adopts the LED lamp beads as a light source to be inserted on the hollow tube, and two pins LED out by the LED lamp beads are connected with a conducting wire in the hollow tube, so that the LED lamp holder structure is attractive and inferior to a tungsten lamp with a lamp shell structure in appearance due to the fact that the LED lamp beads are directly adopted for decoration, and particularly, the pins are directly arranged in the hollow tube, and an isolation structure is not arranged between the two pins, so that the pins are easily contacted due to various external factors, and further the lamp is damaged due to short circuit.

The utility model discloses based on above-mentioned prior art in about the defect of intubate formula ornament lamp, carried out corresponding structural design and improved.

Disclosure of Invention

An object of the utility model is to provide a simple structure, safe and reliable's LED lamp holder structure suitable for intubation type ornament lamp.

In order to achieve the above object, the present invention adopts a LED lamp head structure, comprising a LED lamp bulb, a partition plate and a lamp housing formed by one-time injection molding, wherein the lamp housing has a water-drop-shaped lampshade and a lamp holder extending axially from the lower part of the lampshade, because the lamp housing is formed by one-time injection molding, it can be seen that the lampshade and the lamp holder are of an integral structure, the bottom of the lamp holder has an axial cavity opened along the axial direction and extending to the top end of the lampshade, the part of the axial cavity at the lampshade forms a light source cavity, the part at the lamp holder forms a wiring cavity, the LED lamp bulb has a light source body and two pins for connecting wires LED out from the light source body, the light source body is installed in the light source cavity, at least part of the pins extends into the wiring cavity, the partition plate is arranged between the two pins, and the partition plate is fixedly connected with the lamp holder. In the utility model, the pins can be effectively separated without contact by arranging the partition board between the two pins, thereby avoiding short circuit between the pins, and then the fixed connection structure is directly arranged between the partition board and the lamp holder, so that the top end of the partition board is butted at the bottom of the light source body of the LED lamp bead while the pins are separated, and when the lamp holder is inserted on the hollow tube, the sinking of the LED lamp bead in the hollow tube is avoided; as right the utility model discloses form fixed connection's concrete description between median septum and the lamp stand, its structure is as follows: the edge position of one side of the clapboard is provided with an elastic wane at least partially protruding laterally, a radial buffer slot is arranged between the elastic wane and the clapboard body, a bayonet is arranged on the circumferential wall of the lamp holder at a position corresponding to the elastic wane in the radial direction, the LED lamp beads are fixedly connected through the clamping connection between the elastic wane and the bayonet, and therefore, in the axial direction, the bottom of the elastic wane forms an axial abutting surface, the butting surface is butted with the bottom edge of the bayonet so as to realize the limit in the axial direction, and simultaneously, considering that the axial size of the bayonet can deviate, the side that on the elasticity wane, with the bayonet socket is corresponding sets to the slant face, can effectively avoid the assembly error between elasticity wane and the bayonet socket to lead to the unable card of elasticity wane advances the phenomenon of bayonet socket.

As the utility model discloses a further setting, the top of radial dashpot forms the arc wall structure, and elasticity wane elasticity buffering space in radial direction can effectively be enlargied to this kind of structure.

Through improving prior art's above-mentioned technical scheme, the utility model discloses a LED lamp holder structure has reached the beneficial effect of following tripartite: 1. the production cost is low, the assembly process is simplified: the utility model directly uses the lamp shell formed by one-time injection molding to replace two parts of a tungsten lamp and a lamp holder and the assembly thereof in the prior art; 2. simple structure and safe and reliable: in the prior art, or a structure that a tungsten filament lamp made of glass is matched with an insulating lamp holder is adopted, as described in the background art, the decorative lamp holder structure of the structure has great requirements on the structural performance of the socket, the structure is more complex, and the production cost is higher; if the LED lamp beads are directly adopted, no short circuit between two pins in the hollow tube can be ensured, and potential safety hazards exist; therefore, in the utility model, the lamp housing is formed by one-time injection molding, then the LED lamp bead is inserted into the axial cavity of the lamp housing, then the partition plate is inserted between two pins of the LED lamp bead, the two pins are effectively isolated, and then the axial spacing between the partition plate and the LED lamp bead is achieved (the partition plate is prevented from sinking due to the pull of gravity or other external force) through the clamping type fixed connection directly formed by the elastic wane on the partition plate and the bayonet on the lamp holder, and then the lamp holder is directly inserted on the hollow tube; 3. because the lamp shade of lamp body is for showing in the visible part on ornament lamp fluorescent tube top, therefore the pleasing to the eye degree (decoration effect promptly) when the shape direct influence light source of lamp shade is luminous, for prior art, the appearance shaping cost of glass system tungsten filament lamp is higher, and breakable, consequently, the utility model discloses a lamp shade can be according to customer's requirement and the different shape of customization, reaches various luminous effect, not only limit the utility model discloses a water droplet form lamp shade.
