Description

There is not the cold extremely cloudy pipe liquid crystal lamp of section

Technical field:

The utility model relates to a kind of liquid crystal lamp, relates in particular to the cold extremely cloudy pipe liquid crystal lamp of a kind of nothing section.

Background technology:

The light fixture lamp source of state's intraoral illumination use at present is various in style, and as fluorescent lamp (T8, T5), electrodeless lamp, LED lamp or the like, fluorescent lamp (T8, T5) should not be used for open air, freezer, low temperature place, otherwise can influence the stability of brightness and output; Light efficiency only 40-60 (Lm/V) is low strobe light source, and driver's eyesight is damaged relatively.Fluorescent lamp mercury content height is not recyclable again, and the fluorescent tube caliber is environment-friendly products not greatly, and the fluorescent-lamp tube life-span is short, uses power too big, and power consumption is not energy-conservation.

LED because of light fixture heat build-up auxiliary accessories benefit of a specified duration excessively reduces, radiating effect is poor, cause light decay easily, complex manufacturing process, processing procedure pollute want keyholed back plate, need the high-order encapsulation technology, no reclaim mechanism, cost be higher, the replacement maintenance spare and accessory parts that market does not have unified standard are disposable products, though energy-conservation disposable input is wasteful.

Though if tunnel illumination adopts the high-pressure sodium lamp light efficiency higher, its power consumption heightens still not energy-conservation relatively, light color is yellow partially again, and color rendering is lower, and light source can't be true colors, reduces visual acuity easily; Radiating effect is poor, bulb service life is short.

These lamps exist that light decay is serious, radiating effect is poor, the fluorescent tube bulb service life is short, the scope of application is wideless, the problem of not environmental protection in sum.

The utility model content:

The purpose of this utility model provides the cold extremely cloudy pipe liquid crystal lamp of a kind of nothing section, and it has the good opering characteristic of electric apparatus and luminous efficacy, and good vibration is arranged, and is safe, low in energy consumption, long service life, and volume is little, and is in light weight, the intensity height.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of glass-tube 1, electrode 2, fluorescent material 3 and seal wire 4, the inboard, two ends of glass-tube 1 is provided with electrode 2, and electrode 2 outer ends link to each other with seal wire 4, and glass-tube 1 inwall scribbles fluorescent material 3.

The utility model fluorescent tube contains an amount of mercury and inert gas, and tube inner wall scribbles fluorescent material, and respectively there is an electrode at two ends.After high pressure is added in lamp tube ends, produce secondary behind the minority electrons high-speed impact electrode in the fluorescent tube, begin discharge, after mercury in the pipe is subjected to electronic impact, exciting radiation goes 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 (color of visible light will according to the difference of selected fluorescent material difference).

The utlity model has the good opering characteristic of electric apparatus and luminous efficacy, good vibration is arranged, safe, low in energy consumption, long service life, volume is little, and is in light weight, the intensity height.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment:

With reference to Fig. 1, this embodiment by the following technical solutions: it is made up of glass-tube 1, electrode 2, fluorescent material 3 and seal wire 4, and the inboard, two ends of glass-tube 1 is provided with electrode 2, and electrode 2 outer ends link to each other with seal wire 4, and glass-tube 1 inwall scribbles fluorescent material 3.

This embodiment fluorescent tube contains an amount of mercury and inert gas, and tube inner wall scribbles fluorescent material, and respectively there is an electrode at two ends.After high pressure is added in lamp tube ends, produce secondary behind the minority electrons high-speed impact electrode in the fluorescent tube, begin discharge, after mercury in the pipe is subjected to electronic impact, exciting radiation goes 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 (color of visible light will according to the difference of selected fluorescent material difference).

This embodiment can be done digitlization according to site environment and calculate (colour temperature, lumen) to cooperate the global design needs of building decoration, has both accomplished the dark effect with distinct contrast of suitable graceful light, can cooperate the special purpose computer control system to make multiple change color again.Cold-cathode tube is one of light source the most energy-efficient in the present light source; Its color is abundant and pure, can be used for star hotel indoor and outdoor illumination, urban landmark, contour of building lamp light styling; Outdoor occasions such as the outline of building such as bridge, building, square decorative lighting are the preferred light source of the beautiful engineering in city.Have high brightness, high lumen, energy-efficient, long distance vision better effects if.

Ready-made cold-cathode tube is joined a high-quality dedicated transformer and can be lighted and had only slight light decay in 50,000 hours; And its life-span is not subjected to the influence (about 2 hours of lost of life of incandescent lamp switch) of its switch number of times.Its operating ambient temperature also relaxes greatly compared with common neon light, and its brightness does not have difference between temperature-28-40 ℃, and the luminous flux of the common neon light of light flux ratio of cold-cathode tube is twice, and color developing effect is more true to nature; The penetration power of cold-cathode tube is stronger, and under severe weather conditions, effect is more obvious; And be Green Product.

Claims (1)

1. the cold extremely the moon of the section of nothing is managed the liquid crystal lamp, it is characterized in that it is made up of glass-tube (1), electrode (2), fluorescent material (3) and seal wire (4), the inboard, two ends of glass-tube (1) is provided with electrode (2), and electrode (2) outer end links to each other with seal wire (4), and glass-tube (1) inwall scribbles fluorescent material (3).
