Description
Technical field
The present invention relates to a kind of fitting structure, especially a kind of bushing type fluorescent lamp.
Background technology
At present, tubular fluorescent lamp (fluorescent lamp) mostly is the glass tube two ends that scribble fluorescent material in the wall inboard exciting electrode is installed, and punctures the inert gas in the pipe, makes it to send ultraviolet ray, and further excitated fluorescent powder sends visible light and reaches illuminating effect.A kind of luminous efficiency of fluorescent material, i.e. unit are brightness is fixed, and wants the illumination intensity that reaches different, has only by adjusting light-emitting area and is undertaken.Therefore, set different luminosity by the length of adjusting fluorescent tube usually.Though change the diameter of fluorescent tube to a certain extent the fluorescent material area is increased, be subjected to excitation energy and inert gas and puncture all multifactor influences such as efficient, glass tube intensity, volume, amendatory degree is very limited.Therefore, how increasing in limited volumetric spaces and excite area, is the feasible method that effectively improves luminous efficiency.
Summary of the invention
The object of the invention is, a kind of bushing type fluorescent lamp is provided, and to overcome the defective of above-mentioned conventional art, improves the Energy Efficiency Ratio of conventional lamp, reaches efficient, purpose of energy saving.A kind of bushing type fluorescent lamp of the present invention, be to keep tube diameter and light-emitting area not to reduce under the prerequisite, by reducing fluorescent tube internal work space, improve the interior electron density of lamp works mikey volume relatively to increase excitation energy, reach the purpose that improves luminous efficiency according to this.
Structure of the present invention is as follows:
A kind of bushing type fluorescent lamp of the present invention, be to keep tube diameter and light-emitting area not to reduce under the prerequisite, by inserting in order to reduce the interior pipe in fluorescent tube internal work space, improve the interior electron density of lamp works mikey volume relatively to increase excitation energy, reach the purpose that improves luminous efficiency according to this.
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described.In order clearly to show structural principle of the present invention, accompanying drawing is not according to actual size and scale.

Embodiment
Embodiment one (Fig. 1-3)
A kind of bushing type fluorescent lamp, fluorescent tube is made up of with the sleeve pipe form two different glass tubes of diameter, but forms the interlayer of a filling inert gas between two pipes, promptly excites working space.Lamp tube ends is introduced electrode and is stretched into above-mentioned working space by end cap by end caps.To be circular layout in the interlayer of two glass tubes, corresponding two ends are connected with above-mentioned introducing electrode on this loop filament diameter as the filament of exciting electrode.Fluorescent material is coated on the glass outer tube wall inboard and the inner layer glass tube wall outside.The inner layer glass tube wall also scribbles ultraviolet reflecting film, can be to outer layer glass tube direction uv reflectance.
In view of the above, make the working space of fluorescent tube reduce, but the fluorescent material coated area strengthen on the contrary.The collision probability that intert-gas atoms of filling in the interlayer and the miscarriage of electrode electrons emitted are given birth to improves, and discharges more excitation energy, has improved launching efficiency.Simultaneously, owing to excite area to increase, under the situation of equal energy consumption, effectively improve luminous efficiency, or under the situation of identical luminous intensity, cut down the consumption of energy.The present invention also is arranged to annular with traditional linear filament, has increased the area of filament emitting electrons, makes launching efficiency higher.Again by ultraviolet reflecting film is set, launching efficiency is further improved with reference to the accompanying drawings, a kind of bushing type fluorescent lamp 1, fluorescent tube is by two glass tubes that diameter is different, be that outer tube 11 and interior pipe 12 are formed with the sleeve pipe form, by a pair of end cap 20 mutual sealing and fixing that are positioned at lamp tube ends.Two pairs introduce electrode 22 pass respectively two end caps 20 stretch into outer tube 11 and in the interlayer 10 of pipe 12, as the filament 21 of exciting electrode being circular layout in 10 li in the interlayer of two glass tubes, and respectively with diameter two ends on the annular circumferential relative 2 with introduce electrode 22 and be connected.Fluorescent material 40 is coated on the tube wall outside of the inboard and interior pipe 12 of the tube wall of outer tube 11, and interlayer 10 conducts of inner and outer pipes excite working space, are filled with inert gas.The tube wall inboard of interior pipe 12, the tube wall outside, or the interior outside also scribbles ultraviolet reflecting film 30 (the interior outside of pipe 12 tube walls scribbles the situation of ultraviolet reflecting film 30 simultaneously in Figure 3 shows that) simultaneously, can be in interlayer 10 uv reflectance, improve launching efficiency to fluorescent material 40.The described ultraviolet reflecting film 30 of the pipe 12 walls outside (periphery) working space one side is between fluorescent material 40 and tube wall in being coated in.
Embodiment two (Fig. 4)
A kind of bushing type fluorescent lamp, be similar to embodiment one, fluorescent tube 201 also is to be constituted by inside and outside two different glass tubes of diameter, interlayer between the tube wall inboard of outer tube 211 and the tube wall outside of interior pipe 212 is a working space 210, outer tube 211 wall inboards scribble fluorescent material, the interior pipe 212 walls outside scribbles ultraviolet reflecting film, in order to away from fluorescent tube axis direction uv reflectance, be filled with inert gas in the middle of the interlayer of inner and outer pipes, introduce electrode 222 for two pairs and penetrate the end cap 220 that is sealed in outer tube 211 two ends, and connect filament 221 as exciting electrode.But be with embodiment one difference, the two ends of interior pipe 212 are closed state, pipe 212 is an enclosed construction independently in making, interior pipe 212 can be supported in the outer tube 211 by the supporting construction (figure does not show) of appropriate format, to occupy the space that a part of outer tube 211 surrounds, filament 221 also need not to be confined to loop configuration.
Further, the ultraviolet reflecting film outside that the interior pipe 212 walls outside applies also can scribble fluorescent material, to increase luminous efficiency; Further, but the inboard coating semiconductor conductive layer of interior pipe 212, in order to improve the starter ability.
Among the present invention, interior pipe 212 can be selected any material that is fit to its operational environment and is easy to make for use, the glass that present embodiment adopted for example, but not as limit.
The foregoing description only is to illustrate basic principle of the present invention, not as the qualification of protection range.Variation on any structure of doing according to the principle of the invention does not all exceed connotation of the present invention.
