Description
[technical field]
The utility model relates to a kind of external electrode plane fluorescent lamp.
[background technology]
Existing low pressure gaseous discharge fluorescent lamp (abbreviation fluorescent lamp) is the light source of general lighting, the life-span of this type fluorescent lamp is depended on the life-span of filament electrode, in order to prolong the life-span of fluorescent lamp, prior art is solving the electronic powder amount that how to increase on the filament to increase the life-span and to increase the on-off times of filament by the filament pre-heating Starting mode always, but poor effect, compact fluorescent lamp particularly, the common product life-span, on-off times was about 10000 times at 10000 hours; When being used as the desk lamp with dimmer switch use, the filament electrode life-span is extremely short.
The advantage of external electrode plane fluorescent lamp is: 1, the life-span is long, because electrode does not have filament, solved the problem that life-span is short, the switching surge number of times is low that existing Filament of fluorescent lamp electrode exists, the external-electrode fluorescent lamp electrode applies the electric conducting material formation such as graphite in glass lamp plate external electrode position, the design top electrode life-span can reach the life-span of material for lamp, such as the life-span of glass, the life-span of fluorescent material, particularly the on-off times of external-electrode fluorescent lamp experiment numeral has reached 5,000,000 times, and electrode is still excellent.2, light efficiency is high, and light efficiency generally has two concept: a, light to send end, refers to source efficiency, and b, light receiving terminal refer to the irradiated degree of face to be illuminated, claims illumination efficiency; Light source has experienced point-source of light (such as incandescent lamp), line source (such as straight tube fluorescent lamp) is to the process of area source (flat lamp), because the irradiated place of light receiving terminal face to be illuminated General Requirements is the flat illumination effect, such as the Ceiling light illuminating effect, therefore, point-source of light and line source all must transform by the secondary light-distribution of light fixture and realize flat illumination, this conversion process is so that point-source of light, the light efficiency of line source has reduced many, be that the fluorescent lamp of 65LM/W is by behind the secondary light-distribution of light fixture such as source efficiency, illumination efficiency is reduced to 40-50LM/W, and the luminous efficiency of source of flat lamp is consistent with the illumination light efficiency, generally reaches 50LM/W.3, light quality better, flat lamp are because light-emitting area is large, and light is soft, and free from glare is the requirement of high-quality illumination.Therefore, external-electrode fluorescent lamp is considered to another the revolutionary new light sources after incandescent lamp, fluorescent lamp, Non-polarized lamp and LED.
As shown in Figure 1, the discharge tube 1 of existing external electrode plane fluorescent lamp arranges all be parallel distribution, and end circular arc connects, the electrode 2 parallel both sides outermost that are distributed in discharge tube.Because the glass plate of flat lamp is for satisfying the properties of product requirement, thickness requirement is got over Bao Yuehao, but thin glass plate intensity is also poorer, in the manufacture process of flat lamp such as high temperature sealed knot between discharge tube moulding, the glass plate etc., thin glass plate is out of shape easily, in the stress objective reality lamp product that distortion produces, and product exists the lamp plate heating temp high in the process of lighting a lamp, particularly lamp plate temperature inequality and temperature gradient are large, can make stress increasing in the lamp product, cause easily in the process of lighting a lamp the quality problems that plate splits to occur.Because the discharge tube arrangement of present plane fluorescent lamp is parallel distribution, the temperature inequality and the radial direction temperature gradient that have in use produced circumferential direction are large, particularly take the center as symmetrical structure such as circular flat lamp, the structure generation that is arranged in parallel of this discharge tube to split the plate phenomenon very serious, the external-electrode fluorescent lamp product long-life is produced have a strong impact on; Because being arranged in parallel so that non-luminous electrode is in the flat lamp of the both sides external of lamp plate, particularly circular configuration of discharge tube causes light at the circumferential skewness of lamp plate, causes flat lamp that the installation direction requirement is in use arranged.
The Figure of description that No. 201020225298.3, Chinese utility model patent discloses a kind of structure of plane fluorescent lamp, as shown in Figure 2, this fluorescent lamp glass plate profile is octangle, and discharge channel 1 is parallel distribution on it, the end is the circular arc type syndeton, and electrode 2 is arranged at discharge channel 1 two ends.The plane fluorescent lamp of this structure just exists above-mentioned plate to split and the problem of uneven illumination.
In view of this, the utility model people furthers investigate for the defective of prior art, and has this case to produce.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of illumination uniform external electrode plane fluorescent lamp, and it is not easy to occur splitting the plate phenomenon.
The utility model solves the problems of the technologies described above by the following technical solutions:
A kind of external electrode plane fluorescent lamp, comprise two plate plane glass plates, be provided with discharge tube at least one glass sheets, described discharge tube two ends are provided with electrode, described discharge tube be arranged as lamp plate central distribution around described external electrode plane fluorescent lamp, described electrode is on the periphery of the outer shroud of described discharge tube.
Further, the distribution of described discharge tube is collar plate shape electric furnace shape.
Further, two Archimedes spirals that are distributed as symmetrical centre of described discharge tube connect the discharge tube of formation that communicates in the center.
Further, the discharge tube sectional area in the close centre of described discharge tube is greater than decentre discharge tube sectional area at a distance.
The utility model has the advantage of: because being arranged as around the lamp plate Central Symmetry of discharge tube of the present utility model launches to distribute, electrode is on the outermost periphery, solve the particularly problem of the circumferential temperature distributing disproportionation of the external-electrode fluorescent lamp that is arranged in parallel of circular configuration discharge tube of symmetrical structure, solved the problem of illumination patterns inequality; And by paracentral discharge tube sectional area greater than decentre discharge tube sectional area at a distance, solved the particularly large problem of radial symmetry gradient of the external-electrode fluorescent lamp that is arranged in parallel of circular configuration discharge tube of symmetrical structure; Because being arranged as of discharge tube is reasonable as symmetrical distributed architecture take the center, make the lamp plate of same area, the length of discharge tube is longer, has improved the luminous efficiency of lamp plate.Therefore, the utility model has guaranteed the external-electrode fluorescent lamp product quality, and the market development of external-electrode fluorescent lamp product is significant.
