Problems solved by technology

On the one hand, the black sodium amalgam generated on the surface of the phosphor particles will absorb and irradiate the excitation ultraviolet light with a wavelength of 253.7nm on the surface of the phosphor particles, so that the phosphor particles cannot be fully excited; on the other hand, on the surface of the phosphor particles The black sodium amalgam will reduce the lumen output of the lamp
From the above analysis, it can be seen that the sodium element in the glass is one of the main factors that reduce the lumen maintenance rate of the lamp, but the effect of the commonly used aluminum oxide inner wall coating is not very satisfactory.

Embodiment 1

[0005] Embodiment 1: choose 10nm titanium dioxide and dilute to 4% coating with pure water, bake and solidify. Compared with the commonly used aluminum oxide coating, the lumen maintenance rate of 2000h has increased by 7.8%, and the coating thickness has been measured to be 1.3μm.

Embodiment 2

[0006] Embodiment 2: choose 50nm titanium dioxide and dilute to 5% coating with pure water, bake and solidify, and repeat coating once. Compared with the commonly used aluminum oxide coating, the lumen maintenance rate of 2000h has increased by 7.4%, and the coating thickness has been measured to be 1.0μm.

Embodiment 3

[0007] Embodiment 3: choose 80nm titanium dioxide and dilute to 6% coating with pure water, solidify. Compared with the commonly used aluminum oxide coating, the lumen maintenance rate of 2000h has increased by 7%, and the coating thickness has been measured to be 0.8μm.

Abstract

The invention relates to a fluorescent tube coated with titanium dioxide, belonging to fluorescent lamp field. The invention is characterized in that nanometer titanium dioxide material is used for coating at effective coating thickness. The invention has the advantages that generation of black sodium amalgam is reduced; luminous maintenance rate of the fluorescent tube is increased by 6 to 8 % compared with ordinary alumna coating; service life of the lamp is greatly prolonged.

Description

technical field [0001] The invention relates to the field of fluorescent lamp tubes, in particular to a fluorescent lamp tube with an inner wall coating. Background technique [0002] Limited to the current economic and technological level in our country, although the price of glass tube materials used in the manufacture of compact fluorescent lamps in my country is relatively low, the quality is poor. The poor quality is mainly manifested in two aspects: one is the high sodium content, and the other is the The photoblackening of the fluorescent lamp is serious. With the compactness of the fluorescent lamp, the wall load of the lamp tube is further increased, and the working temperature of the lamp tube is also continuously increased. The increase in the temperature of the glass tube accelerates the thermal diffusion of sodium ions in the glass. These sodium ions will diffuse from the interior of the glass to the inner surface of the tube, where they will recombine with elect...
