Embodiment Construction

[0006] according to figure 1 The present invention shown is composed of double-layer lamp tubes, the outer wall of the inner glass tube and the inner wall of the outer glass tube are coated with pure tricolor phosphor powder, and the effective luminous area is increased by 50%. The evacuated space of the fluorescent tube is the inner wall of the outer layer and the outer wall of the inner layer. The space is reduced, the power is reduced, and the current is also proportionally reduced, and the light efficiency is increased by about 30%. The light cannot be emitted, which reduces the luminous flux. If the thickness of the powder coating on the inner wall of the outer lamp tube is reduced by half, the light transmittance will increase, and the corresponding luminous flux will also increase. The inner glass tube is equipped with thermal insulation material, which can ensure the temperature of the fluorescent tube and avoid the power increase of the fluorescent tube due to the low...

Abstract

The invention provides a high-efficiency double-layer internal-reflecting fluorescent tube in order to solve the problems that the fluorescent tube has low luminous flux and short service life in the prior art and make specific overall improvement on the existing fluorescent tube, which is completely different from the existing fluorescent tube. The fluorescent tube of the invention comprises an outer glass tube (1), internal coating powder (2) for the outer glass tube (1), an inner glass tube (5), external coating powder for the inner glass tube (5), a ring-shaped filament (3), a reflecting film (6) and a heat-insulating material (7), wherein 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 fluorescent powder coating 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 particularly an H-shaped and ring-shaped glass tube cap provided with the ring-shaped filament, thus forming a device for preventing mercury spot and black spot.

Description

technical field [0001] The invention relates to the field of fluorescent lamp tubes, in particular to a high-efficiency double-layer internal reflection fluorescent lamp tube. Background technique [0002] Limited to the current economic and technological level of our country, the luminous area of ​​straight fluorescent tubes manufactured in our country is limited, and the luminous intensity has reached the extreme. It is difficult to increase the luminous flux under the same power. The fluorescent tube is lit for a long time, and the light decay is very large, and the light decay also determines the life of the fluorescent tube. The temperature of the lamp tube increases, which accelerates the diffusion of sodium ions in the glass. Through thermal diffusion, the sodium ions run to the surface of the phosphor particles and react with mercury atoms, forming black sodium amalgam. The generation of black sodium amalgam on the surface of the phosphor particles will absorb the e...
