Abstract
The utility model relates to the technical field of T8 illuminating light manufacturing. The utility model provides a T8 light tube structure capable of improving light distribution. A T8 light tube generally comprises an aluminum profile, a light cover, a light source, an aluminum base plate for fixing the light source, and a power supply for supply power to the aluminum base plate, wherein the aluminum profile is fastened with the light cover into a whole so as to form a shell; the light source is welded on the aluminum base plate so as to form a light source plate and is arranged in the shell; and the light source plate is combined with the aluminum profile into a whole through a pluggable assembly manner. Two installation insertion slots are extended from faces of two sides of a bottom part of the aluminum profile, towards to the light cover, and are symmetrically arranged. The aluminum profile of the T8 light tube is improved as follows: a bottom part of the aluminum profile comprises a U-shaped slot depressed towards an inner part of the aluminum profile, and inclined parts for respectively connecting two ends of the U-shaped slot to the two sides of the bottom part of the aluminum profile, wherein an opening direction of the U-shaped slot is directed to one face of the light cover; and an included angle formed by each inclined part and each side of the U-shaped slot is an obtuse angle. The T8 light tube structure capable of improving light distribution is applied to optimization of light distribution of the T8 light tube.

Technical field
The utility model relates to T8 illumination lamp & lantern manufacturing technology field, is specifically related to a kind of structure of having improved the T8 fluorescent tube of luminous intensity distribution.
Background technology
The T8 fluorescent tube is a kind of of fluorescent lamp (or claiming fluorescent lamp, light pipe, fluorescent tube), and diameter is 1 inch, about 25 millimeters, belongs to a kind of of gas-discharge lamp.Its electrification activates mercury vapour in argon or neon, form plasma and send short wave ultraviolet, makes phosphorus matter send visible fluorescence with illumination.
Traditional T 8 fluorescent tubes comprise that the aluminium base in aluminium section bar (pedestal), lampshade, lamp source, fixed light source reaches the power supply for the aluminium base power supply; Aluminium section bar and lampshade fasten and are formed as one shell; The lamp source is welded in and forms the lamp source plate on the aluminium base; And be arranged in the shell, and lamp source plate and aluminium section bar be combined as a whole through known plug formula fit, and its concrete structure is following: there are the two row's draw-in grooves that extend along aluminium section bar on aluminium section bar two bottom sides limit; Notch is provided with in opposite directions, and the lamp source plate inserts between two row's draw-in grooves and fixes as one with aluminium section bar from an end of aluminium section bar.Yet existing aluminium section bar bottom is typically designed to planar structure, under the cooperation of lampshade; Make that the lighting angle in LED lamp source is limited; Generally can only reach 120 °, and then can not satisfy the requirement of some application scenarios, the application of T8 fluorescent tube is caused certain limitation.
The utility model content
The utility model technical problem to be solved is a kind of improved T8 lamp tube structure that can enlarge the LED lighting angle to be provided, to solve the described problem of background technology.
In order to solve the problems of the technologies described above; A kind of T8 lamp tube structure that improves luminous intensity distribution of the utility model; The aluminium base that this T8 fluorescent tube generally comprises aluminium section bar, lampshade, lamp source, fixed light source reaches the power supply for the aluminium base power supply, and aluminium section bar and lampshade fasten and be formed as one shell, and the lamp source is welded in and forms the lamp source plate on the aluminium base; And be arranged in the shell, and lamp source plate and aluminium section bar are combined as a whole through plug formula fit.Wherein, the aluminium section bar two bottom sides is extended two towards the one side of lampshade slot is installed, and said two installation slots are symmetrical set.Aluminium section bar to the T8 fluorescent tube improves as follows: the aluminium section bar bottom comprises a U type groove that forms to the aluminium section bar inner recess; And the rake that the two ends of said U type groove is connected to the aluminium section bar two bottom sides respectively; The opening direction of said U type groove is towards the one side of lampshade, and the formed angle of side of said rake and U type groove is the obtuse angle.
Further, the formed angle of side of said rake and U type groove is 101 °.
Further, the rake of said both sides extends length-specific to the center and forms two inclination extensions, and is preferred, and distance is 9.5mm between these two inclination extensions.
Further, two sides of said U type groove are 12.6mm apart.
Further, said aluminium section bar extends to the center respectively near the both sides of bottom, forms the groove of the circular arc of two symmetries.Further preferred, said two grooves are at a distance of 19.5mm.
Further, the cross section outward flange indentation of said T8 fluorescent tube aluminium section bar.
The utility model adopts above-mentioned project organization, through the U type groove and the rake of aluminium section bar bottom, can make the lighting angle less than 120 ° in existing LED lamp source increase to 180 °, has expanded the application scenario of T8 fluorescent tube.
