Description

The luminous tube of fluorescent lamp

Technical field

The utility model provides a kind of luminous tube of fluorescent lamp, more specifically says so and utilizes geometrical principle, provides a kind of and does not have luminous dead angle (dark space), do not have counteracting (optical loss) each other, improves the luminous tube of brightness, power saving and fluorescent lamp simple in structure.

Background technology

Because the efficient of fluorescent lamp is high and have suitable output beam, is widely used in room lighting.In recent years, the lamp tube shapes of fluorescent lamp has been developed the legerity type fluorescent tube that the luminous tube of elongated caliber is given bending, as U-shaped fluorescent tube, helical lamp etc. except traditional straight tube shape, annular, make that fluorescent lamp can miniaturization and variation, and install easily.

Habitual fluorescent lamp with U-shaped fluorescent tube, in order to make it that enough brightness can be arranged and to make its volume unlikely excessive, must be by several the luminous lamp tubes that are set up in parallel, but because luminous lamp tube does not side by side have proper alignment, cause distribution curve flux inhomogeneous, and produce than the clear zone with respect to the dark space in this clear zone, make overall brightness that non-uniform phenomenon be arranged.

In order to solve the problem that fluorescent tube does not side by side have proper alignment, conventional techniques is to utilize several U-shaped fluorescent tubes to arrange to form circular novel florescent lamps, makes the light uniformity more consistent, and can reach the effect than power saving.This habitual luminous lamp tube structure, though can make distribution curve flux comparatively even, the structure that it utilizes the configuration of several luminous lamp tubes to finish exists comparatively complexity and heat efficiency problem such as lack perfection of structure.

In order to overcome several existing shortcomings of U-shaped fluorescent tube of combinations thereof, conventional techniques as shown in Figure 1, this utility model is to be configured as the helical form luminous tube with a tubes, it is arranged at luminous tube 1 shape in the shape of a spiral on the lamp socket 2, each curls up a few with identical up around the footpath both ends of this helical form luminous tube 1, and it can obtain distribution curve flux uniformly when comparing with above-mentioned U-shaped fluorescent tube, and can improve luminous flux by the length that increases fluorescent tube, it is shaped by a luminous lamp tube, and it is simple in structure.

Though that helical form luminous tube shown in Figure 11 habitual U-shaped fluorescent tube has is simple in structure, brightness increase, light uniformity advantage preferably, but its structure is imperfection still, as shown in Figure 2, its identical problem that between the luminous tube in footpath, exists the luminosity of to cancel out each other, be that the light (shown in arrow among the figure) that its upper strata luminescence segment sends can be subjected to stopping of its lower floor's luminescence segment, the light that luminous tube is sent is not fully utilized, and the lighting function that does not have 360 degree exists the shortcoming that illumination reduces and causes consuming energy.

Summary of the invention
