Abstract
The utility model discloses a planar light source with single filaments and low melting-point glass powder sealing edges. The planar light source comprises a first glass substrate, a second glass substrate and an electrode bar; opposite side surfaces of the first glass substrate and the second glass substrate are respectively provided with a fluorescent layer; the periphery of the first glass substrate and the second glass substrate adopts the low melting-point glass powder sealing edges; inner sides of two opposite sealing edges are provided with two linear filaments which have the same length and are adaptive to the length of the glass substrates at the same direction; and each linear filament leads out a wire through low melting-point glass powder sealing edges at the same side. The planar light source of the utility model is advantageous in simple structure and convenient usage, and can assist in effectively solving the problem of nonuniformity in light emission of a planar light source.
Description
Technical field
The utility model relates to a kind of planar light source, particularly relates to a kind of planar light source of single filament low glass powder edge sealing.
Background technology
At present, the structure of employed planar lighting device is generally a plurality of parallel fluorescent lamps are set between the two plate plane glass on the market, and is as far as possible even in order to reach the light that makes the picture back side, needs to adopt reasonable Arrangement fluorescent tube interval, select lighting tube brightness, arrange the method realizations such as floodlight plate.
Not only there is larger waste in said method at aspects such as planar lighting device equipment and power consumption, and on illuminating effect, can't really realize the even distribution of light.
The utility model content
The purpose of this utility model provides a kind of planar light source of single filament low glass powder edge sealing, can produce uniform planar light, has effectively solved the inhomogeneous problem of distribution of light of existing planar light source.
For achieving the above object, the planar light source of a kind of single filament low glass powder of the utility model edge sealing, described planar light source comprises the first glass substrate, the second glass substrate and filament, described the first glass substrate and the second glass substrate apparent surface are provided with fluorescence coating, adopt the low glass powder edge sealing around the first glass substrate and the second glass substrate, two relative edge sealing inboards be arranged in parallel two isometric, with the wire filament that the equidirectional length of glass substrate adapts, filament is outwards drawn wire by homonymy low glass powder edge sealing.
Further, described the first glass substrate, the second glass substrate are rectangle.
Further, the placement that is parallel to each other of described the first glass substrate and the second glass substrate, described the first glass substrate is positioned at the top, the second glass substrate is positioned at the below.
Further, fill mercury vapour and argon gas between described the first glass substrate, the second glass substrate.
The flat light source structure of the utility model single filament low glass powder edge sealing is simple, easy to use, has effectively solved the inhomogeneous problem of planar light source distribution of light.
Description of drawings
Fig. 1 is the utility model section structure schematic diagram.
Fig. 2 is the utility model plan structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
Such as Fig. 1, shown in 2, the planar light source of the utility model single filament low glass powder edge sealing, comprise the first glass substrate 1, the second glass substrate 2 and filament 4, wherein the first glass substrate 1 and the second glass substrate 2 are flat glass and are parallel to each other placement, the first glass substrate 1 is positioned at the top, the second glass substrate 2 is positioned at the below, the first glass substrate 1, the second glass substrate 2 opposite flanks are provided with fluorescence coating 5, adopt low glass powder 3 edge sealing around the first glass substrate 1 and the second glass substrate 2, two relative edge sealing inboards be arranged in parallel two isometric, the wire filament 4 that adapts with the equidirectional length of glass substrate, filament 4 is outwards drawn wire 7, the first glass substrates 1 by homonymy low glass powder edge sealing, fill mercury vapour and argon gas 6 between the second glass substrate 2.
During plugged, two isometric filaments 4 make helium, neon or the xenon ionization in the lamp box and cause planar arc discharge, excite the light-emitting phosphor of the first glass substrate 1, the second glass substrate 2 opposite flank fluorescence coatings 5, realize the luminous of planar light source.
The flat light source structure of the utility model single filament low glass powder edge sealing is simple, easy to use, has effectively solved the inhomogeneous problem of existing planar light source light.
Above-mentioned example is preferred implementations more of the present utility model; in addition; those skilled in the art are in the situation that comprehension the utility model thought, can also make numerous other execution modes, and these execution modes all should be within protection range of the present utility model.
