Abstract

The utility model provides a novel fluorescent tube, aims to solve the problems of low luminous flux and short service life of a fluorescent tube in the prior art, specific improvements are made to the integral fluorescent tube, and a structure totally different from an existing fluorescent tube is provided. The novel fluorescent tube consists of an outer glass tube (1), internal coating powder (2) for the outer glass tube, a ring-shaped filament (3), an inner glass tube (5), external coating powder (4) for the inner glass tube, a reflecting film (6) and a heat-insulating material (7), and the fluorescent tube is characterized in that the outer wall of the inner layer and the inner wall of the outer layer of the double-layer glass tube are coated with pure trichromatic fluorescent powder, and the thickness of the coating powder on the inner wall of the outer glass tube is reduced by half; the heat-insulating material is loaded in the internal space of the inner glass tube; the inner wall of the inner glass tube is coated with the reflecting layer; and the tube cap is an H-shaped and ring-shaped glass tube cap provided with the ring-shaped filament, thereby forming a device for preventing mercury spots and black spots.

Description

A kind of novel fluorescent lamp tube

Technical field

The utility model relates to the fluorescent tube field, particularly a kind of novel fluorescent lamp tube.

Background technology

At present, the Radiating fin wind inducing structure light-emitting area that China makes is limited, luminous intensity has also reached limit, is being difficult to improving luminous flux under the constant power.Fluorescent tube is lighted for a long time, and light decay is very big, and light decay has also determined the life-span of fluorescent tube.Lamp hole temperature improves, and accelerates sodium ion diffusion in the glass, and surface and the mercury atom of going to fluorescent powder grain by the thermal diffusion sodium ion react, and generate the sodium amalgam of black.Thereby generate the black sodium amalgam will to absorb irradiation on the one hand be that 253.7 excited ultraviolet can not be excited fluorescent powder grain fully to the surperficial wavelength of fluorescent powder grain on fluorescent powder grain surface; On the other hand, the black sodium amalgam on the fluorescent powder grain surface will make the lumen output of lamp reduce.Have to thicken the thickness of dusting in order to reach desirable luminous flux, but light transmittance reduces greatly also simultaneously.Caliber overstriking fluorescent material efficient lighting area is also big, and power has strengthened.Fluorescent tube two filament is in the condition of high temperature when starting, the metallic molecule of filament is excited, and has possessed high-energy, and space loss towards periphery easily owing to the stopping and cool off and be attached on the tube wall of tube wall, thereby forms the vestige of the black that we see.By last surface analysis as can be known, space size, lamp holder design all are the main causes that the fluorescent tube luminous flux is low, the life-span is low in the internal layer area of glass tube, sodium element, dusting thickness, the pipe.

The utility model content

According to above technical problem, the utility model provides a kind of novel fluorescent lamp tube, in order to solve the problem that the fluorescent tube luminous flux is low in the prior art, the life-span is low, will make concrete improvement to the integral body of fluorescent lamp, be different from the structure of existing fluorescent lamp light modulation fully.The present invention is made up of dusting (2) in outer layer glass tube (1), the outer tube, loop filament (3), inner layer pipe dusting (4), inner layer glass tube (5), reflective membrane (6), insulation material (7), it is characterized in that the outer inwall of double-layer glass tube inner layer outer wall scribbles pure three primary colors fluorescent powder, the thickness of glass outer inside pipe wall dusting reduces half.Insulation material is equipped with in the inner layer glass tube inner space.The internal layer tube inner wall scribbles reflector layer, and lamp holder is the ring-like glass lamp holder of loop filament, H, is anti-mercury spot, blackhead device.

The utility model is made of dual-layer lamp tube, and inner layer glass tube outer wall, glass outer inside pipe wall scribble pure three primary colors fluorescent powder, and efficient lighting area increases by 50%.It is outer inwall and inner layer outer wall that fluorescent tube vacuumizes the space, the space has reduced, power descends, the electric current decline that also just is directly proportional, and light efficiency has improved about 30%, existing fluorescent tube dusting is all thicker, hindered part light and sent out to come out, reduced luminous flux, if the thickness of outer tube inner wall dusting reduces half, light transmittance will improve, and the corresponding light flux also can improve.Insulation material is equipped with in inner layer glass tube inside, can guarantee the temperature of fluorescent tube, avoids crossing the low power that influences fluorescent tube because of ambient temperature and goes up.In order to improve the luminous flux of fluorescent tube, improve the light efficiency utilance, scribble reflector layer at fluorescent tube internal layer tube inner wall.Lamp holder is the ring-like glass lamp holder of loop filament, H, is anti-mercury spot, blackhead device.Fluorescent tube two mercury spot, blackhead phenomenon also can obviously reduce, and so more effectively light fluorescent tube, thereby have improved the life-span of fluorescent light.

Embodiment

Be made of dual-layer lamp tube according to the utility model shown in Figure 1, inner layer glass tube outer wall, glass outer inside pipe wall scribble pure three primary colors fluorescent powder, and efficient lighting area increases by 50%.It is outer inwall and inner layer outer wall that fluorescent tube vacuumizes the space, the space has reduced, power descends, the electric current decline that also just is directly proportional, and light efficiency has improved about 30%, existing fluorescent tube dusting is all thicker, hindered part light and sent out to come out, reduced luminous flux, if the thickness of outer tube inner wall dusting reduces half, light transmittance will improve, and the corresponding light flux also can improve.Insulation material is equipped with in inner layer glass tube inside, can guarantee the temperature of fluorescent tube, avoids crossing the low power that influences fluorescent tube because of ambient temperature and goes up.In order to improve the luminous flux of fluorescent tube, improve the light efficiency utilance, scribble reflector layer at fluorescent tube internal layer tube inner wall.Lamp holder is the ring-like glass lamp holder of loop filament, H, is anti-mercury spot, blackhead device.Fluorescent tube two mercury spot, blackhead phenomenon also can obviously reduce, and so more effectively light fluorescent tube, thereby have improved the life-span of fluorescent light.
