Abstract
The utility model relates to a low-frequency electrodeless lamp which comprises a rectangular tube (1), magnetic cores (2, 3) and a high frequency exciter (10). The magnetic core (2) is provided with two semicircular openings (4, 5) in the transverse direction, the magnetic core (3) is provided with two semicircular openings (6, 7) in the transverse direction, and each magnetic core with the two semicircular openings is fixed and mounted along the transverse direction of the tube via a metal ring (1) with a projection (11); and the high-frequency exciter (10) is connected with the magnetic cores (2, 3).
Description
Technical field
The utility model relates to lighting field, particularly relates to a kind of low frequency electrodeless lamp.
Background technology
In the situation that incandescent lamp is banned use of by countries in the world, low frequency electrodeless lamp becomes the suitable selection of current energy-efficient light source, become the ideal product of running energy conservation contract EMC pattern, but, the current coupler magnetic core as one of low frequency electrodeless lamp vitals is when application, can design respectively a mounting groove at the longer two ends of rectangle fluorescent tube distance, a pair of semicircular ring magnetic core is used respectively at two ends.With this technical scheme, there is following shortcoming:
One, can make to leave certain spacing so that magnetic core to be installed in the middle of rectangle fluorescent tube, so that the volume of low frequency electrodeless lamp cannot dwindle, thereby cause supporting lampshade volume larger, and light fixture coupling difficulty comparatively, cannot reach effect small and exquisite, attractive in appearance;
When two, existing low frequency electrodeless lamp is applied, need two sleeve clamps respectively the semicircular ring magnetic core at two ends to be fixed, cannot avoid fee of material and labour cost.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of low frequency electrodeless lamp.
Described a kind of low frequency electrodeless lamp, comprise rectangle fluorescent tube (1), magnetic core (2,3), high frequency excitation device (10), it is characterized in that, described magnetic core arranges semicircle opening (4,5,6 in a lateral direction, 7), magnetic core bonding are being installed respectively up and down along fluorescent tube horizontal direction, and described high frequency excitation device (10) connects with magnetic core (2,3).
Preferably, the bonding in a lateral direction becket of described fluorescent tube, the inner side bonding of outside and magnetic core diplopore, the outside bonding of inner side and fluorescent tube.
Preferably, described becket two ends have thrust.
Preferably, the material of described becket is aluminium, iron, copper.
According to a kind of low frequency electrodeless lamp described in the utility model, bring following beneficial effect:
One, because rectangle fluorescent tube middle ware is apart from dwindling, thereby make Non-polarized lamp volume-diminished, easy and conventional light fixture matches, and reaches effect small and exquisite, attractive in appearance;
Two, the utility model has substituted two traditional double annulus magnetic cores with the magnetic core of two semicircle openings respectively with a pair of, only need a mounting points, use a sleeve clamp, not only be convenient to install, also reduced material cost and labour cost, favourable raising operating efficiency.
Accompanying drawing explanation
Fig. 1 is the stereogram according to a kind of low frequency electrodeless lamp of preferred implementation of the present utility model;
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, to make those skilled in the art can implement according to this with reference to specification word and accompanying drawing.Fig. 1 is a kind of low frequency electrodeless lamp stereogram according to preferred implementation of the present utility model.As shown in Figure 1, according to a kind of low frequency electrodeless lamp preferred embodiment of the present utility model, comprise rectangle fluorescent tube (1), magnetic core (2,3), described fluorescent tube is rectangle fluorescent tube, and the space (13) in the middle of axial direction can be in any range.Described magnetic core (2,3) can first be made magnetic core the magnetic core with diplopore as represented in Fig. 3, by magnetic core along long axis direction to cutting, the magnetic core to after cutting is fixed on and on fluorescent tube, forms effect as shown in Figure 1 with furniture.Due to a pair of, be with respectively two semi-circular hole (8,9) magnetic core is fixing with two ends band thrust (11) one beckets (12) along fluorescent tube cross-sectional direction, because the width of this gap (13) can dwindle arbitrarily according to the actual needs and amplify, can and market on conventional light fixture mate.
In use, mainly by way of electromagnetic induction, Energy Coupling is arrived in rectangle fluorescent tube, make the gas avalanche ionization in bulb, form plasma, plasma excited atom gives off ultraviolet ray while returning to ground state, the fluorescent material of bulb inner wall is subject to ultraviolet ray excited generation can see light.
Claims (4)
1. a low frequency electrodeless lamp, comprise rectangle fluorescent tube (1), magnetic core (2,3), high frequency excitation device (10), it is characterized in that, described magnetic core arranges 2 semicircle openings (4,5,6 in a lateral direction, 7), along fluorescent tube horizontal direction, installing respectively up and down with a pair of described magnetic core, described high frequency excitation device (10) connects with magnetic core (2,3).
2. a kind of low frequency electrodeless lamp according to claim 1, is characterized in that the described bonding in a lateral direction becket of fluorescent tube (12), and becket outside bonds with the inner side of magnetic core diplopore, becket inner side and the outside bonding of fluorescent tube.
3. a kind of low frequency electrodeless lamp according to claim 2, is characterized in that described becket two ends have thrust (11).
4. a kind of low frequency electrodeless lamp according to claim 3, is characterized in that the material of described becket is aluminium, iron, copper.
