CN201117626Y - Helical lamp tube florescent lamp cool end - Google Patents

Abstract

The utility model provides a cold end of a spiral fluorescent lamp. The currently known cold end of the spiral fluorescent lamp is shown in Figure 1. The structure can impact the cold end to adjust Hg steam pressure and increase the light penetration amount when the lamp is ignited in the position as shown in the figure, the ascending of hot air necessarily leads to the temperature ascending of the cold end. Therefore, in the utility model, at least a cold end [3] with a bulb opening towards a lamp holder is arranged on the lamp section closest to the lamp holder. As the temperature of the cold end is low, the capacity of adjusting Hg steam pressure is greatly increased. Compared with the prior cold end (as shown in Figure 1), the light penetration amount is increased almost by 10 percent.

Description

A kind of cold junction of helical lamp fluorescent lamp

Technical field

The utility model relates to a kind of helical lamp fluorescent lamp, particularly a kind of cold junction of helical lamp fluorescent lamp.

Background technology

The cold junction of present known helical lamp fluorescent lamp as shown in Figure 1, this structure since when fluorescent tube when lighting as the figure position, the rising of hot-air must cause the rising of cold junction temperature, thereby influences the pressure that cold junction is regulated mercury vapour, improves the effect of luminous flux.For this reason, people have thought a lot of methods, but otherwise be exactly that the cold junction effect is undesirable, otherwise be exactly that technology is too complicated.

Summary of the invention

For the better technical problem that solves above-mentioned cold junction poor effect, improve luminous flux better, the technical scheme that the utility model provides is on nearest that section fluorescent tube of lamp socket, to be arranged to a rare bubble mouthful cold junction [3] towards lamp socket as Fig. 2.

On nearest that section fluorescent tube of lamp socket, be arranged to a rare bubble mouthful cold junction [3] towards lamp socket.Because people think such cold junction and can cause fluorescent material in this deposition and ineffective always, therefore never the someone used, and we think that this is best cold junction, and the problem of fluorescent material fully can otherwise address.In addition, also can make more than one cold junction (as Fig. 3), cold junction is many more, though the cold junction effect is good more, technology complicates, and therefore will decide the cold junction number as the case may be.We technology relatively in, the cold junction in the utility model is because at the bottom of the temperature, the ability of regulating mercury vapor pressure improves a lot, with the cold junction (as Fig. 1) of prior art relatively, improved luminous flux nearly 10%.

Description of drawings

Fig. 1 is the prior art schematic diagram, and wherein 1 is fluorescent tube, and 2 is lamp socket, and 4 is cold junction.Fig. 2 is the utility model schematic diagram, and wherein 1 is fluorescent tube, and 2 is lamp socket, and 3 is cold junction.Fig. 3 has the schematic diagram of an above cold junction for the utility model, and wherein 1 is fluorescent tube, and 2 is lamp socket, and 3 is cold junction (being made up of two cold junctions)

Embodiment

Embodiment one: get one of fluorescent tube, blow a cold junction by Fig. 2, and connect into lamp routinely, with the lamp comparison (Fig. 1) of prior art, luminous flux increases by 10%.

Embodiment two: get one of fluorescent tube, blow two cold junctions by Fig. 3, and connect into lamp routinely, with the lamp comparison (Fig. 1) of prior art, luminous flux increases by 11%.

Claims (1)

1. the cold junction of a helical lamp fluorescent lamp is characterized in that on nearest that section fluorescent tube of lamp socket, has a bubble mouthful cold junction [3] towards lamp socket at least.
