Abstract
The utility model discloses a low-power cold cathode glow discharge fluorescent lamp, which comprises a lamp holder, an outer glass shell, a lamp tube, an electrode outgoing line, a series resistor and the like, wherein the lamp tube is designed into a U shape with a thin tube diameter, and rare earth tricolor fluorescent powder is coated on the inner wall of the lamp tube, thereby solving the dark space of light distribution under the straight tube-shaped lamp tube and leading the lamp tube to emit light uniformly; one outgoing line is connected in series with a series resistor, so that the stability and reliability of discharge can be effectively improved; the outer glass shell is designed into a special shape, so that the structure of the straight tube-shaped lamp tube is approximately changed into a bulb-shaped structure, and the lamp tube has the advantages of attractive appearance, firmness, practicability, low price and the like.
Description
The utility model belongs to the electric light source field, further relates to a kind of cold cathode glow discharge fluorescent lamp.
Existing cold cathode glow discharge fluorescent lamp is the straight tube shape, and it is made up of mercury and argon gas in lamp holder, straight tube shape outer glass tube, conductive layer, straight-pipe fluorescent lamp, interior electrode, lead-out wire and the straight-pipe fluorescent lamp.The effect of fluorescent tube outer conducting layer mainly is that the lead-out wire away from electrode in that of lamp holder is connected with the power supply leading-in end, the resistance value that has with conductive layer as the discharge keep-alive voltage of fluorescent tube with keep voltage.Straight tube shape outer glass tube is used for protecting the fluorescent tube outer conducting layer and prevents the people from touching conductive layer and shocked by electricity.The profile of this fluorescent lamp is the straight tube shape, and fluorescent tube is not only thick but also long, and is very not attractive in appearance.In addition, under the fluorescent tube dark space of luminescence distribution, for most of use occasions, be not suitable for very much.
The purpose of this utility model be to manufacture and design a kind of novel structure, attractive in appearance, practical, cheap, luminous evenly, the cold cathode glow discharge fluorescent lamp that is significantly improved of luminous efficiency.
The utility model is achieved in that cold cathode glow discharge fluorescent lamp is made up of lamp holder, outer glass bulb, fluorescent tube, series resistance, fixed head, and its fluorescent tube is a tubule footpath U-shaped shape, and outer envelope designs spheroiding also can be that long-neck type, taper shape, cylinder are tapered.
The utility model has the advantages that: fluorescent tube adopts tubule footpath U-shaped shape, has not only reduced the length of lamp, and from luminescence distribution, the dark space under can eliminating; It is approximate bulb-shaped that outer envelope designs becomes, and has attractive in appearance, firm, easy to use, cheap advantage.
Be further described below in conjunction with accompanying drawing:
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the ball-type fluorescent lamp made from the utility model;
Fig. 3 is the long-neck type fluorescent lamp made from the utility model;
Fig. 4 is the pyramid type fluorescent lamp made from the utility model;
Fig. 5 is the tapered fluorescent lamp made from the utility model of cylinder.
A kind of embodiment of the present utility model, cold cathode glow discharge fluorescent lamp by lamp holder 1, outer glass bulb 2, fluorescent tube 3, conductive layer 4, phosphor powder layer 5, interior electrode 6, electrode outlet line 7, series resistance 8, fixed head 9, and fluorescent tube 3 in mercury and argon gas form.As shown in Figure 1, a fixed head 9 is housed, is used for fixing fluorescent tube 3 at lamp holder 1 end opening.One of electrode outlet line 7 is connected with lamp holder 1 inwall, and another root lead-out wire 7 connects series resistance 8 and is connected with lamp holder 1 upper end.The upper end of outer glass bulb 2 and lamp holder 1 are combined closely.
Claims (5)
1, cold cathode glow discharge fluorescent lamp comprises that lamp holder, outer glass bulb, fluorescent tube, series resistance and fixed head form, and the fluorescent tube that it is characterized in that described fluorescent lamp is a tubule footpath U-shaped shape, and outer glass bulb is ball-type, also can is that long-neck type, pyramid type, cylinder are tapered.
2, cold cathode glow discharge fluorescent lamp according to claim 1 is characterized in that described fluorescent tube internal diameter is between 4～10 millimeters.
