Abstract
The utility model relates to an energy-saving fluorescent lamp with thermal shield, which is composed of a lamp tube, a ballast, a ballast casing, and a standard lamp holder, wherein, the lamp tube is arranged in a transparent or a semi-transparent outer cover; the outer cover is sealed by vacuum seal, and is fixed on the ballast casing, and the atmospheric pressure in the outer cover is lower than 100 mmHg. The utility model can be isolated from the external heat, so the utility model can work with better luminous efficiency at normal temperature, and can also normally work at low temperature and obtain better luminous efficiency.
Description
The utility model belongs to lighting field, relates to a kind of power saving fluorescent lamp, refers to a kind of heat shielding power saving fluorescent lamp especially.
Power saving fluorescent lamp is when work, and there is different temperature in different zones on the surface of the light tube, and the temperature in the zone that temperature is minimum is called the cold-zone temperature.The cold-zone temperature has an optimum value, and this optimum value is most effective corresponding to lamp luminescence.When environment temperature was very low, for example below 0 ℃ the time, the luminous efficiency of fluorescent lamp was very low, even can not work.Just there is the shortcoming of this cisco unity malfunction at low temperatures in a kind of electricity-saving lamp that United States Patent (USP) 4853591 discloses.
Above-mentioned shortcoming in view of existing power saving fluorescent lamp, the purpose of this utility model is to provide a kind of power saving fluorescent lamp of vacuum heat shielding, this fluorescent lamp not only can work in preferable luminous efficiency under general temperature, and at low temperatures also can operate as normal and obtain preferable luminous efficiency.
For achieving the above object, a kind of vacuum heat shielding power saving fluorescent lamp that the utility model provides comprises fluorescent tube, fluorescent tube ballast, ballast shell and standard lamp head, its characteristics are the outer cover that described fluorescent tube places a transparent or semitransparent material, described outer cover is vacuum seal and is fixed on the ballast shell that its internal gas pressure is lower than 100mmHg.
Below in conjunction with accompanying drawing, further specify design feature of the present utility model and effect, wherein:
Fig. 1 is the front view of an embodiment of heat shielding power saving fluorescent lamp of the present utility model;
Fig. 2 a-2g expresses the adoptable multiple shape of fluorescent lamp outer cover of the present utility model.
See also the embodiment of the utility model heat shielding power saving fluorescent lamp shown in Figure 1, this power saving fluorescent lamp is by fluorescent tube 1, fluorescent tube ballast 2, ballast shell 3 and standard lamp head 4 are formed, its characteristics are: the outside of fluorescent tube 1 be covered with one transparent or semitransparent (for example off-white color or floating in whitewash frosted) outer cover 5, this outer cover 5 is vacuum seal and is fixed on the fluorescent tube ballast shell that its internal gas pressure is lower than 100mmHg.This fluorescent tube 1 and outer cover 5 can be fixed on the ballast shell by a connector (not shown).
As everyone knows, vacuum insulation can prevent that the conduction of heat is lost, also can avoid the influence of ambient temperature to inside simultaneously.Be in when fluorescent tube under the state of vacuum insulation, the temperature of cold-zone depends mainly on the heat that self produces during lamp works.And be subjected to external influence less.Under the temperature (for example 25 ℃) of standard, the fluorescent tube through rationally designing is worked under the structure of vacuum insulation, and the cold-zone temperature should be in optimum value.When this lamp during in the work of different environment temperature, because the vacuum heat-insulation effect has been arranged, the cold-zone temperature of fluorescent tube also is near the optimum value, thereby has improved the luminous efficiency of lamp greatly.When environment temperature is very low (for example below 0 ℃), because vacuum insulation heat protection has been arranged, fluorescent tube is in the energising preheating and during build-up of luminance, heat can not scatter and disappear because of conduction, and lamp hole temperature rises, just can build-up of luminance work through the time fluorescent tube of not growing.The cold-zone temperature of fluorescent tube still is far below optimum value behind the build-up of luminance, but after a period of time, by the heat of discharge generation, the cold-zone temperature is progressively close to optimum value, and it is normally luminous that fluorescent tube is entered into.
In addition, for those skilled in the art, the shape of outer cover 5 can be various, and for example projection shape, pyriform, the mushroom shown in Fig. 2 a-2g eats shape, tubular, olive shape, protruding olive shape and sphere etc. respectively.Equally, used lamp tube shapes also can be various in the utility model, for example U-shaped, dual U-shaped, three U-shapeds, H shape, two H shape, circle and spirality etc.
For advantage of the present utility model is described better, the existing power saving fluorescent lamp that a power saving fluorescent lamp of the present utility model is identical with a type compares test, and the environment temperature during the best light efficiency of these two kinds of lamps is near 25 ℃.Two kinds of lamps are under the varying environment temperature, luminous efficiency and duty such as following table that work records:
| The electricity-saving lamp specification | The light efficiency Lm/W of lamp | ||||
| 35 ℃ of environment temperatures | 25 ℃ of environment temperatures | 15 ℃ of environment temperatures | 0 ℃ of environment temperature | Environment temperature-15 ℃ | |
| The utility model electricity-saving lamp | 58.2 | 59.8 | 56.6 | 51.4 | 45.2 |
| General electricity-saving lamp | 53.5 | 60.5 | 47.0 | 25.3 | Can not work |
Can draw the utility model electricity-saving lamp from the data that detect following advantage is arranged:
1. when variation of ambient temperature, the light efficiency of electricity-saving lamp of the present utility model descends far fewer than general electricity-saving lamp.
2. electricity-saving lamp of the present utility model at low temperatures can operate as normal, therefore is suitable for colder area and uses or outdoor application.
3. electricity-saving lamp of the present utility model is owing to there is a vacuum seal protection outer cover, and it has protected fluorescent tube and electrode to be not easy oxidation, thereby has improved the dependability of lamp.
Claims (4)
1. heat shielding power saving fluorescent lamp, be made up of fluorescent tube, ballast, ballast shell, standard lamp head, it is characterized in that, described fluorescent tube places a transparent or semitransparent outer cover, described outer cover vacuum seal also is fixed on the ballast shell, and its internal gas pressure is lower than 100mmHg.
2. power saving fluorescent lamp as claimed in claim 1 is characterized in that, described outer cover to be shaped as pyriform or projection shape or mushroom-shaped or olive shape or protruding olive shape tubular or spherical.
