Abstract
The utility model discloses a coupler used in an electrodeless lamp, which comprises a heat dissipation rod, at least four magnetic cores and coils. At least two grooves are arranged on the lateral face of the heat dissipation rod in recessed mode at intervals. At least two magnetic cores vertically arranged are installed in each groove. The coils wind around the magnetic cores and the periphery of the heat dissipation rod. The coupler is capable of generating a large magnetic field and enabling a bulb in the electrodeless lamp to shine normally.
Description
Technical field
The utility model relates to a kind of coupler, particularly a kind of coupler that is used for electrodeless lamp.
Background technology
Coupler is a kind of power that an excitation power supply is produced can being coupled in the bulb, thereby makes the device that described bulb is shinny.
Existing described coupler mainly comprises: a heat-radiating rod, described heat-radiating rod are provided with two grooves; Two magnetic cores are installed in respectively in each described groove; And a coil, described coil closely is wound in the periphery of described magnetic core and described heat-radiating rod.
When the electric current of described excitation power supply generation passed through described coil, two described magnetic cores produced certain magnetic field.Yet described coupler only contains two described magnetic cores, and the magnetic field that is produced is smaller, and can't reach the shinny needed magnetic field intensity of described bulb, thereby causes the described bulb can't be normally shinny.
The utility model content
The purpose of this utility model is to provide a kind of can produce the coupler in big magnetic field.
For realizing above-mentioned utility model purpose, the utility model provides a kind of coupler, comprises heat-radiating rod, at least four magnetic cores and coil; The side of described heat-radiating rod at least two grooves that set to the concave, two described grooves are provided with at interval; At least two described magnetic cores that are arranged above and below of each described groove installing; Described coil is wound in the periphery of described magnetic core and described heat-radiating rod.
The utility model is divided into two described magnetic cores that are arranged above and below with single described magnetic core of the prior art, compare with single magnetic core of the prior art, the setting because two described magnetic cores are arranged above and below, therefore, the space of two shared horizontal directions of described magnetic core can not increase, and increase another magnetic field between two described magnetic cores in each described groove and produce point, thereby make total magnetic field increase, so that described bulb can be normally shinny.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
Three-dimensional exploded view when Fig. 1 does not install coil for the utility model coupler;
Fig. 2 is the cutaway view of coupler of the present utility model.
Embodiment
Come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
Please refer to Fig. 1, Fig. 2, the utility model coupler is a coupling coupler in a kind of in the electrodeless lamp that is applied to, and it comprises that a heat-radiating rod 1, two following magnetic cores 2 and two go up magnetic core 3, a coil 4 and bases 5.
Described heat-radiating rod 1 is column type, and described heat-radiating rod 1 has a bottom 11, and be connected with described bottom 11 a top 12, the bottom of described bottom 11 is fixed on the described base 5.The side on the described top 12 described grooves 13 of two grooves 13, two that set to the concave are provided with at interval, and two described grooves 13 with the central shaft of described heat-radiating rod 1 serve as axle axisymmetricly.A described magnetic core 2 down of each described groove 13 installing and a described magnetic core 3 of going up that is stacked in described magnetic core 2 tops down.
The number of turn of described coil 4 is a circle 90-110 circle, has a gap 41 between the described coil 4 of each circle.Described coil 4 is set around described magnetic core 2 down, described periphery of going up the described top 12 of magnetic core 3 and described heat-radiating rod 1, and the distance of the top of the distance of the bottom of described coil 4 and the described bottom surface of magnetic core 2 down and described coil 4 and the described upward end face of magnetic core 3 is respectively less than 1.5 centimetres.
An electric current that produces when an excitation power supply is during by described coil 4, except the lower surface 21 and the described upper surface 32 of going up magnetic core 3 of described down magnetic core 2 produces respectively the magnetic field, the upper surface 22 of described magnetic core 2 down and described lower surface 31 of going up magnetic core 3 produce another magnetic field respectively, compared with prior art, total magnetic field increases, thereby makes that described bulb can be normally shinny.
In addition, owing to have a gap 41 between the described coil 4 of each circle, the heat that makes described coil 4 produce when switching on can distribute in time, thereby makes described coil 4 maintain a lower temperature, reduces the loss of described coil 4 effectively.
In other embodiments, each described groove 13 can be installed three described magnetic cores, and three described magnetic cores are upper, middle and lower respectively and pile up setting, produces another magnetic field between every two adjacent described magnetic cores, can reach the effect that strengthens magnetic field equally.
