Abstract
The utility model relates to a lamp, and provides a novel energy-saving lamp tube which is good in illumination effect, high in energy conservation efficiency, long in service life and low in manufacturing cost. The novel energy-saving lamp tube comprises a light-emitting lamp tube and lamp caps arranged at the two ends of the light-emitting lamp tube. Ballast circuits and starting circuits are arranged in the lamp caps, and electrodes connected with electric supply are arranged outside the lamp caps. The novel energy-saving lamp tube further comprises an externally-connected cold end which is a long and thin glass pipe, a fluorescent powder layer is arranged on the pipe outer wall of the externally-connected cold end, the externally-connected cold end is arranged in the internal axis of the light-emitting lamp tube in a penetrating mode, the two ends of the externally-connected cold end penetrate out of the lamp caps respectively, and the portions, penetrating out of the lamp caps, of the externally-connected cold end are perpendicular to the electrodes outside the lamp caps and are close to the end surfaces of the lamp caps. A reflecting layer is arranged on the inner wall of the top of the light-emitting lamp tube.
Description
Technical field
The utility model relates to light fixture, particularly a kind of energy-saving lamp tube.
Background technology
Support class light fixture is generally being used in business, industrial circle widely, still part comes with some shortcomings, such as: when some customer requirement electric energy is higher, will not reach because being absorbed in power savings desirable illuminating effect, in order to reach desirable illuminating effect, electric energy has just been beaten a discount, affect client's investment cycle, thereby client's investment buying energy-saving lamp is lack confidence; Also under overheated or excessively cold environment temperature, greatly shorten its service life simultaneously.
Summary of the invention
Therefore,, for above-mentioned problem, the utility model proposes that a kind of good illumination effect, energy-saving efficiency are high, long service life, energy-saving lamp tube that cost is low.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of energy-saving lamp tube, comprise luminous lamp tube and the lamp holder of being located at luminous lamp tube two ends, in described lamp holder, be provided with ballasting circuit and starting circuit, described lamp holder is also provided with the electrode being electrically connected to city outward, also comprise external cold junction, described external cold junction is a slender glass tube, the pipe outer wall of described external cold junction is provided with phosphor powder layer, described external cold junction is arranged on the inner axis of luminous lamp tube and the two ends of external cold junction passes respectively lamp holder, it is perpendicular and this passes the part of lamp holder and the end face of lamp holder is pressed close to electrode outside lamp holder that described external cold junction passes the part of lamp holder, described luminous lamp tube top inner wall is provided with reflector layer.
Further improve, the reflector layer in described luminous lamp tube top inner wall is extended on the dual-side flushing with axis by top.
Further improve, described reflector layer is nanometer reflecting coating.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: by external cold junction being set in luminous lamp tube inside, on the outer wall of external cold junction, phosphor powder layer is set simultaneously, in luminous lamp tube top inner wall, reflector layer is set, make electricity-saving lamp of the present utility model to start to fast stable luminescence and to improve brightness by the phosphor powder layer on external cold junction, can be by the light centralized lighting of fluorescent tube by reflector layer is set at top, improve illumination, by external cold junction, fluorescent tube is dispelled the heat simultaneously, thereby make electricity-saving lamp of the present utility model compare power saving rate up to 65% with existing fluorescent lamp, illumination promotes 25%, increase the service life more than 1,000 hours simultaneously, and the utility model cost is low, can wide popularization and application.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, the disclosed energy-saving lamp tube of the present embodiment, comprise luminous lamp tube 1 and lamp holder 2 and the external cold junction 3 of being located at luminous lamp tube 1 two ends, in described lamp holder 2, be provided with ballasting circuit and starting circuit, the outer electrode 4 being electrically connected to city that is also provided with of described lamp holder 2, described external cold junction 3 is a slender glass tube, the pipe outer wall of described external cold junction 3 is provided with phosphor powder layer 5, described external cold junction 3 is arranged on the inner axis of luminous lamp tube 1 and the two ends of external cold junction 3 passes respectively lamp holder 2, described external cold junction 3 pass the part of lamp holder 2 with electrode 4 outside lamp holder 2 perpendicular and this part that passes lamp holder 2 press close to the end face of lamp holder 2, described luminous lamp tube 1 top inner wall is provided with reflector layer 6, reflector layer 6 in described luminous lamp tube 1 top inner wall is extended on the dual-side flushing with axis by top, described reflector layer 6 is nanometer reflecting coating.
The utility model is by arranging external cold junction in luminous lamp tube inside, on the outer wall of external cold junction, phosphor powder layer is set simultaneously, in luminous lamp tube top inner wall, reflector layer is set, make electricity-saving lamp of the present utility model to start to fast stable luminescence and to improve brightness by the phosphor powder layer on external cold junction, can be by the light centralized lighting of fluorescent tube by reflector layer is set at top, improve illumination, by external cold junction, fluorescent tube is dispelled the heat simultaneously, thereby make electricity-saving lamp of the present utility model compare power saving rate up to 65% with existing fluorescent lamp, illumination promotes 25%, increase the service life more than 1,000 hours simultaneously, and the utility model cost is low, can wide popularization and application.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
