Abstract
The utility model discloses a bulb shell which is composed of an upper bulb shell and a lower bulb shell; the lower end of the lower bulb shell is provided with a connector fixed with a lamp holder, the outer diameter of the connector is less than that of an energy-saving lamp tube, the upper end thereof is provided with a placement port for containing the energy-saving lamp tube, and the bore diameter of the placement port is more than the outer diameter of the energy-saving lamp tube; the upper bulb shell is in a crown shape, the lower end of the upper bulb shell is provided with an opening connected with the placement port of the upper end of the lower bulb shell. The bulb shell is suitable for assembling the bulb type energy-saving lamp of which the diameter of the bulb shell opening part is less than the outer diameter of the energy-saving lamp tube, so as to utilize the limit space in the bulb shell to increase the length of a discharging circuit of the lamp tube and improve the light efficiency of the lamp.
Description
Technical field
The utility model relates to the technology of energy-saving bulb, and is special relevant with its cell-shell structure.
Background technology
In the prior art, the structure that a kind of energy-saving bulb arranged as shown in Figure 1, mainly form by Lighthead assembly 10, cell-shell 20, circuit board 30 and power saving fluorescent lamps 40, cell-shell 20 covers on the Lighthead assembly 10, circuit board 30 is installed in the Lighthead assembly 10, power saving fluorescent lamps 40 is installed on the Lighthead assembly 10 and is in the cell-shell 20, and power saving fluorescent lamps 40 is connected with circuit board 30.During use, after the energising, luminous by circuit board 30 control power saving fluorescent lampss 40, light sees through cell-shell 20, reaches the illumination effect.
It is not difficult to find after careful observation that this energy-saving bulb is because the bore of cell-shell 20 is little, guarantee that power saving fluorescent lamps 40 can insert in the cell-shell 20, the external diameter of power saving fluorescent lamps 40 must be less than the bore of cell-shell 20, this causes the external diameter of power saving fluorescent lamps 40 also little, and the discharge road is long shorter, and light efficiency is low.
At the problems referred to above, the inventor researchs and develops out a kind of cell-shell structure that is suitable for energy-saving bulb, and is long so that the assembling outside dimension, can make full use of the discharge road of space increase fluorescent tube limited in the cell-shell greater than the power saving fluorescent lamps of cell-shell bore, improve the light efficiency of lamp, this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of power saving fluorescent lamps of assembling outside dimension greater than the cell-shell bore, and it is long to make fluorescent tube fully increase the discharge road in the limited space of cell-shell, the cell-shell of the light efficiency of raising lamp.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of cell-shell is made up of last cell-shell and following cell-shell; The lower end of following cell-shell has one and is fixedly coupled mouth with Lighthead assembly, and the bore of this connector is less than the external diameter of power saving fluorescent lamps, and the upper end has a posting port of putting into for power saving fluorescent lamps, and the bore of this posting port is greater than the external diameter of power saving fluorescent lamps; Last cell-shell is crown, and the lower end has an opening that is connected with the upper end posting port of following cell-shell.
Described cell-shell down is inverted round platform.
The described connecting line of going up cell-shell and following cell-shell is on the cross section of electricity-saving lamp cell-shell maximum gauge.
The described cell-shell of going up is connected together by supersonic welding with following cell-shell.
After adopting such scheme, the utility model is divided into cell-shell and following cell-shell with cell-shell, during assembling, be to descend the connector of cell-shell to be fastened on the Lighthead assembly earlier, again power saving fluorescent lamps is put into down the cell-shell and is fixed on the Lighthead assembly from posting port, then, will go up the posting port that cell-shell is welded on down cell-shell again, promptly make energy-saving bulb.Like this, the utility model can be put into greater than the power saving fluorescent lamps of cell-shell bore for outside dimension, utilizes the discharge road of free space increase fluorescent tube long, and light efficiency improves thereupon.
Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment
As shown in Figures 2 and 3, be preferred embodiment of the present utility model.
A kind of cell-shell that is applicable to energy-saving bulb is made up of last cell-shell 21 and following cell-shell 22, can be connected together by supersonic welding.
Following cell-shell 22 is inverted round platform or similar shape.The lower end of following cell-shell 22 has one and is fixedly coupled mouthfuls 23 with Lighthead assembly 1, and the bore of this connector 23 is less than the external diameter of power saving fluorescent lamps 4, and the upper end has a posting port 24 of putting into for power saving fluorescent lamps 4, and the bore of this posting port 24 is greater than the external diameter of power saving fluorescent lamps 4.
Last cell-shell 21 is crown, and the lower end has an opening 25 that is connected with the upper end posting port 24 of following cell-shell 22.
During the utility model assembling, be to descend the connector 23 of cell-shell 22 to be fastened on the Lighthead assembly 1 earlier, again power saving fluorescent lamps 4 is put into down the cell-shell 22 from posting port 24, and be fixed on the Lighthead assembly 1 to form and be electrically connected with circuit board 3, then, the opening 25 that to go up cell-shell 21 again is fastened on down the posting port 24 of cell-shell 22 by ultrasonic wave, promptly makes energy-saving bulb, as shown in Figure 4.Last cell-shell 21 preferably is on the cross section of electricity-saving lamp cell-shell 2 maximum gauges with the connecting line of following cell-shell 22, like this, and can be for the diameter maximum of the power saving fluorescent lamps of assembling 4.The utility model can be put into greater than the power saving fluorescent lamps of cell-shell bore for outside dimension, utilizes the discharge road of free space increase fluorescent tube in the cell-shell long, and light efficiency improves thereupon.
The above only is an embodiment of the present utility model, is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection range of this case.
