Abstract
The utility model discloses a double-layer cold cathode lamp tube comprising a cold cathode lamp tube (1), an accommodation tube body (2) and seal end caps (3), wherein the at least one cold cathode lamp tube (1) is arranged inside the accommodation tube body (2); the two ends of the accommodation pipe body (2) are provided with the seal end caps (3); the seal end caps (3)are provided with lamp feet (31); and the inside of the accommodation tube body (2) is filled up with inert gas, and the outer surface of the accommodation tube body (2) is provided with a reflective coating. The cold cathode lamp tube is arranged inside the accommodation tube body filled with the inert gas so that not only may a thin-caliber cold cathode tube be protected and protected from fragmentation, but also the thermal conduction probability is reduced, the surrounding temperature of the cold cathode lamp tube is thus increased quickly, and the high luminous efficiency output of the cold cathode lamp tube may be enabled; and the reflective coating disposed on the outer surface of the accommodation tube body may also enable the light extraction efficiency of the cold cathode lamp tube to be improved.
Description
Technical field
The utility model relates to a kind of cold cathode fluorescent lamp, particularly a kind of double-deck cold cathode fluorescent lamp with preferable light extraction efficiency.
Background technology
Cold cathode fluorescent lamp is one of light source the most energy-efficient in the present light source, belong to a kind of low-pressure mercury discharge lamp pipe, more more reliable than conventional incandescent bulb, it is little that cold cathode fluorescent lamp has a volume, power consumption is little, advantages such as the life-span is long, but because itself is low in energy consumption, the heat that produces is few, make light source reach enough mercury-vapor pressure at short notice, make it to reach maximum luminous efficiency (35 ℃ time luminous efficiency the highest), need there be the regular hour poor, lacks by tens seconds, at most a few minutes, therefore, owing to the time of the intensification of this light source and the mercury vapor pressure that reaches capacity is long.In addition because the caliber of cold cathode fluorescent lamp is thinner, comparatively frangible.
The utility model content
For solving the problems referred to above of prior art, the double-deck cold cathode fluorescent lamp that the utility model purpose is to provide a kind of can be lighted fast, light extraction efficiency is high.
In order to reach above-mentioned purpose, the utility model adopts following concrete technical scheme: a kind of double-deck cold cathode fluorescent lamp, comprise cold cathode fluorescent lamp, ccontaining body and end cover, at least being provided with a described cold cathode fluorescent lamp places in the ccontaining body, described ccontaining body two ends are provided with end cover, described end cover is provided with lamp base, the inner inert gas of filling of described ccontaining body, and its outer surface is provided with reflecting coating.
End cover is fixed at described cold cathode fluorescent lamp two ends, according to bright dipping briliancy needs, the quantity of cold cathode fluorescent lamp is set.
Described reflecting coating covers half outer surface of ccontaining body.
The beneficial effects of the utility model are as follows: the utility model places cold cathode fluorescent lamp in the ccontaining body of filling inert gas, not only can protect the thinner cold-cathode tube of caliber, prevent that it is cracked, and can be by reducing heat conducting probability, thereby improve the environment temperature of cold cathode fluorescent lamp fast, thereby make cold cathode fluorescent lamp can reach high light efficiency output the short time; At the containing tube external surface reflecting coating is set, also can improves the light extraction efficiency of cold cathode fluorescent lamp.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As Fig. 1; shown in Figure 2; a kind of double-deck cold cathode fluorescent lamp; comprise cold cathode fluorescent lamp 1; ccontaining body 2 and end cover 3; at least being provided with a described cold cathode fluorescent lamp 1 places in the ccontaining body 2; can protect the thinner cold cathode fluorescent lamp of caliber 1; prevent that it is cracked; according to bright dipping briliancy needs; select the quantity of the cold cathode fluorescent lamp 1 of setting to be fixed on the end cover 3 at ccontaining body 2 two ends; described end cover 3 is provided with lamp base 31; at the ccontaining body 2 inner inert gases of filling; can pass through to reduce heat conducting probability, thereby improve the environment temperature of cold cathode fluorescent lamp fast, thereby make cold cathode fluorescent lamp 1 can reach high light efficiency output the short time; be provided with the reflecting coating 4 of half outer surface that covers ccontaining body 2 at the outer surface of ccontaining body 2, also can improve the light extraction efficiency of cold cathode fluorescent lamp 1.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection range.
Claims (3)
