Abstract
The utility model discloses a magnet ring used for an HFED, which comprises at least two magnet ring segmental arcs with concentric circle. The magnet ring is characterized in that the cross section of the magnet ring can take the shape of an ellipse, a circle or a totally obtuse-angled polygonal; and at least one longitudinal concave metallic channel is formed in an optional position along the magnet ring surface. The utility model has the advantages of high coupling efficiency, low probability of damaging lamp tubes, easy routing of the connection line between magnet ring coils and no prominence of magnet ring bodies.
Description
Technical field
The utility model relates to a kind of lighting magnet ring, the magnet ring that uses on specifically a kind of electrodeless lamp.
Background technology
Utilize the mercuryvapour in the electric wave energy deexcitation fluorescent lamp of wireless high frequency, radio frequency or microwave section, make the outer-shell electron of mercury atom obtain energy and send ultraviolet photon, the fluorescent material absorption that it is painted on the lamp wall is just sent the electrodeless lamp of visible light after 20th century, the middle and later periods nineties put goods on the market, good because of the continuity of its spectrum, start flicker free, allow that mains fluctuations are big, the life-span is long, so be described as the green electric light source of the best so far by the boundary of throwing light on, various countries.Existing in the market electrodeless lamp generally is made up of lamp bracket, fluorescent tube, magnet ring, is wound with induction coil with lead on magnet ring, and magnet ring is fixed on the fluorescent tube by geometrical clamp, and magnet ring is square section shape.There is following shortcoming in this magnet ring: induction coil can not fit tightly magnet ring during coiling on the magnet ring of square section, produce big space, reduced magnetic coupling efficient, square section magnet ring sharp comer is damaged fluorescent tube with electrodeless lamp tube wall collision easily, be difficult for when the magnet ring volume is less cooperating fluorescent tube to install, line is difficult for cabling between the coil on the magnet ring.If have and a kind ofly can improve the magnet ring coupling efficiency, not fragile again fluorescent tube, the magnet ring that is easy to cabling between the coil connecting line is applied on electrodeless lamp, is bound to produce due social benefit and economic benefit.
Summary of the invention
The purpose of this utility model is to solve following technical problem, a kind of magnet ring of electrodeless lamp is provided, the magnet ring coupling efficiency that solves electrodeless lamp in the past is low and many relatively consuming electric powers adopt the square section to have the sharp edge angle to damage lamp tube wall easily, the problem that line exposes between the coil on the magnet ring.
For solving the problems of the technologies described above, the utility model adopts the magnet ring shape of cross section help increasing coupling area to improve the magnet ring coupling efficiency, and the method for adopt eliminating the corner of magnet ring or eliminating sharp-pointed corner as far as possible avoids magnet ring to damage fluorescent tube, simultaneously be convenient on the magnet ring cabling of line between the coil opening the longitudinal concave metallic channel on the magnet ring, it is characterized in that: the cross section of described magnet ring is oval, circular, whole polygon at obtuse angles.Along optional position, magnet ring surface a longitudinal concave metallic channel is set at least.
The utility model is owing to improved the cross section of magnet ring, make on the one hand induction coil on the magnet ring cross section, can fit tightly magnet ring and make the maximization of magnet ring cross-sectional area during coiling, improve coupling efficiency, eliminated the sharp-pointed corner of magnet ring on the other hand again simultaneously, be difficult for breaking electrodeless lamp fluorescent tube.Longitudinal concave metallic channel along the magnet ring surface makes the good cabling of line energy between the magnetic ring coil and does not give prominence to magnetic ring body.Cooperate with the reasonable of fluorescent tube thereby improved magnet ring, really saved the energy, avoided the loss late of fluorescent tube.

Embodiment
A kind of electrodeless lamp magnet ring of the utility model comprises at least two concentrically ringed magnet ring segmental arcs 1, and the cross section of described magnet ring is a polygon oval, circular, whole obtuse angles, along optional position, magnet ring surface a longitudinal concave metallic channel 2 is set at least.Adopted a kind of magnet ring of oval cross section in magnet ring embodiment at Fig. 1, Fig. 2, Fig. 3, electrodeless lamp shown in Figure 4, be divided into two concentrically ringed magnet ring segmental arcs 1 and be combined into a complete annulus, and have a longitudinal concave metallic channel 2 at inner surface middle part along magnet ring.
Claims (2)
1, a kind of electrodeless lamp magnet ring comprises at least two concentrically ringed magnet ring segmental arcs (1), it is characterized in that: the cross section of described magnet ring is polygon oval, circular, whole obtuse angles.
