Abstract

A plastic cold cathode fluorescence lamp belongs to the realm of lighting fixtures, and consists of a luminous body and a metal conductor connected to the luminous body. The luminous body is a vacuumbody based on a carrier made of transparent plastics, the inner wall of the vacuum body is coated with fluorescent powder, and an opening for air exhaust and perfusion purposes and an electrode inserthole are formed on the vacuum body. The metal conductor includes two strip-shaped metal bodies provided with a plurality of electrodes, the metal bodies are additionally installed on two sides of theluminous body, the electrodes stick into the internal space of the luminous body and the contact of the metal conductor and the luminous body is sealed. The absence of a filament in the fluorescencelamp contributes to a reduction in accumulation of heat inside the lamp tube, thereby prolonging the service life of the lamp. Meanwhile, because materials for the carrier of the luminous body are plastic, the utility model is low in cost, allows for shape variations, and is very easy to manufacture and process. The luminous body can be directly manufactured into an ultra-thin light box for displaying ads, photos, and images, through discretionary combinations, or applied in combination with a plurality of plastic cold cathode fluorescence lamps in constituting a medium-and-large-scale ultra thin light box. Furthermore, the utility model can be used as a backlight source for an LCD color television, in particular as a direct-injection type backlight source for a large-screen LCD color television.

The purpose of this utility model reaches like this: a kind of plastics cold-cathode fluorescence lamp is characterized in that: fluorescent lamp is made up of the metallic conductor that is connected on luminous element and the luminous element.It is the vacuum body of carrier, coated inner wall fluorescent material with the transparent plastic that described luminous element is one, and it is provided with and bleeds, pours into and use opening.Described metallic conductor is two, is installed at the both sides of luminous element respectively.Metallic conductor is the bullion body, and it is provided with some electrodes, and electrode inserts mouth by the electrode on the luminous element and extend into the luminous element inner space, metallic conductor and the sealing of luminous element contact position.

Being provided with some reinforcings in the luminous element supports.

The outer surface of described metallic conductor adds insulating material.

The utility model has the advantages that:

1, these plastics cold-cathode fluorescence lamp does not have filament, has alleviated the gathering of heat in fluorescent tube, has reduced energy resource consumption, has increased the useful life of fluorescent lamp.

2, the luminous element of plastics cold-cathode fluorescence lamp employing transparent plastic is that carrier is made, and cheap, production and processing is very simple.Can be made into multiple shape as required, thin type flat board for example, tubulose, halfpipe etc.Also can make the different shape that various plastic material processing technologys allow moulding, overcome the single shortcoming of glass lamp shape.

3, the luminous element of plastics cold-cathode fluorescence lamp possesses the original advantage of arbitrary combination, can directly be made into the ultrathin lamp box of advertisement, photo, picture, or a plurality of cold-cathode fluorescence lamp is used in combination large-scale ultrathin lamp box in the formation.Certainly, the plastics cold-cathode fluorescence lamp also can be used as the backlight of lcd color tv in the panel TV, and especially the direct-lit backlight of the lcd-tv of large-screen is used.

(5) embodiment

Accompanying drawing has provided a specific embodiment of utility model.

In the present embodiment, the transparent plastic luminous element is made the thin type writing board shape.The plastics cold-cathode fluorescence lamp is by luminous element 1, and metallic conductor 2 is formed.Luminous element is to be carrier with the transparent plastic, at the vacuum body of the coated inner wall fluorescent material of transparent plastic.Be provided with on the luminous element bleed, perfusing hole 1-1, by bleed, perfusing hole 1-1, pour into required small amounts of mercury, vacuumize back perfusion required argon, thin inert gas such as neon and sealing.In luminous element 1, be provided with a plurality of structural strengthenings and support 1-2, make it under situation about vacuumizing, also can keep sound construction and indeformable.Metallic conductor 2 is two identical bullion bodies, is installed at the both sides of luminous element respectively, closely contacts with luminous element.Some electrodes 3 on two metallic conductors extend into the inner space of luminous element, do not contact with luminous body wall.With matching is that luminous element is provided with an electrode insertion mouthful 1-3, and electrode inserts mouth by electrode and extend in the luminous element.For guaranteeing that luminous element must be the requirement of vacuum, the contact position of metallic conductor and luminous element has installed encapsulant additional and has sealed.

The shape of metallic conductor, size become according to the difference of the moulding of luminous element, size, and the principle of variation is the shape that metallic conductor should adapt to luminous element, with it closely contact.And what, length, size of the electrode on the metallic conductor also can be provided with as required.

The procedure of processing of these plastics cold-cathode fluorescence lamp is, earlier metallic conductor is installed in the both sides that coated inner wall has the luminous element of fluorescent material, guarantee that electrode is inserted into the inner space of luminous element on request, the place that metallic conductor is contacted with luminous element seals with encapsulant then, and guaranteeing does not have the space between metallic conductor and the luminous element.At last, by bleeding on the luminous element, perfusing hole, pour into required small amounts of mercury.Vacuumize back perfusion required argon, thin inert gas such as neon and sealing.

Because the critical piece of plastics cold-cathode fluorescence lamp adopts respectively and makes, the mode of simple combination is for the moulding of light fixture provides very abundant space.Luminous element is that carrier is made with the transparent plastic, and processing, moulding are very easy, thereby can conversion go out many different moulding light fixtures.Can directly be made into the ultrathin lamp box of advertisement, photo, picture, the direct-lit backlight of lcd-tv that also can be used as backlight, the especially large-screen of lcd color tv in the panel TV is used.Then can select the luminous element of different shaping indoors, reach different visual effects according to wall lamp, the various different needs of desk lamp.

Operation principle: conventional fluorescent lamps utilizes electrode that external electric energy is converted into gas discharge institute energy requirement in the lamp.Cold-cathode fluorescence lamp then is after applying high-frequency voltage is added in lamp tube ends, produces secondary behind the minority electrons high-speed impact electrode in the fluorescent tube, begins discharge.After mercury in the pipe was subjected to electronic impact, exciting radiation went out the ultraviolet light of 253.7nm, and the ultraviolet excitation of generation is coated in the fluorescent material on the inside pipe wall and produces visible light, the color of visible light will be according to the difference of selected fluorescent material difference.The plastics cold-cathode fluorescence lamp also meets this principle.Therefore the plastics cold-cathode fluorescence lamp should with the supporting use of corresponding electric ballast.
