Description
Technical field
The utility model relates to lighting technical field, in particular a kind of LED fluorescent tube.
Background technology
On existing market, existing LED fluorescent tube is that the driving power of LED fluorescent tube is arranged in the formed cavity volume of heat-dissipating casing, so for the larger driving power that takes up room under holding, it is larger that the cross-sectional area of heat-dissipating casing often arranges, a lot of heat-dissipating casings has accounted for the more than 60% of whole fluorescent tube cross-sectional area, and then cause whole lamp luminescence part less than 40%, the light efficiency of such fluorescent tube is very poor, does not meet the requirement of user to fluorescent tube light efficiency.
And the life-span of LED chip is conventionally more than 40,000 hours, and the life-span of driving power is relatively short, so in regular maintenance, conventionally need to change driving power, and because driving power being arranged in the cavity volume of heat-dissipating casing, change the inconvenience that when dismounting can be very, can produce thus the expense of a large amount of maintenance and repairs, do not meeting the requirement of user to cost.
Therefore, prior art has yet to be improved and developed.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of LED fluorescent tube, LED driving power is arranged in LED lamp holder, thereby has reduced the area of heat-dissipating casing cross section, increase the area of PC cover cross section, increased the light efficiency of LED fluorescent tube.
The technical solution of the utility model is as follows:
A fluorescent tube, comprises PC cover, is connected with a heat-dissipating casing with described PC cover, is fastened on the lamp holder at the two ends after described PC cover is connected with described heat-dissipating casing; Wherein, it also comprises the LED driving power being arranged in described lamp holder.
Described LED fluorescent tube, wherein, the cross section of described PC cover and described heat-dissipating casing is all circular arc, and central angle corresponding to the circular arc of described heat-dissipating casing cross section is less than the central angle corresponding to circular arc of described PC cover cross section.
Described LED fluorescent tube, wherein, described heat-dissipating casing comprises a substrate and an arc, and described substrate and described arc are integral type structure, and on described substrate, paster is provided with a plurality of LED lamp pearls.
Described LED fluorescent tube, wherein, the length of described LED driving power is less than the length of described lamp holder.
Described LED fluorescent tube, wherein, the corresponding central angle of circular arc of described PC cover cross section is 240 degree; The corresponding central angle of circular arc of the cross section of described heat-dissipating casing is 120 degree.
Described LED fluorescent tube, wherein, described heat-dissipating casing is aluminium shell.
The utility model provides a kind of LED fluorescent tube, because the length of LED driving power is less than the length of lamp holder, and then in described lamp holder, be provided with LED driving power, thereby central angle corresponding to the circular arc that makes heat-dissipating casing cross section is less than the central angle corresponding to circular arc of PC cover cross section, make the light-emitting area of LED fluorescent tube be greater than 1/2nd of circumference, increased the light efficiency of LED fluorescent tube, and easily change LED driving power, it is safeguarded simple, convenient for maintaining is changed, and has saved the cost of maintenance.
Accompanying drawing explanation
Fig. 1 is the preferred embodiment perspective view of a kind of LED fluorescent tube provided by the utility model.
Fig. 2 is the preferred embodiment partial exploded view of a kind of LED fluorescent tube provided by the utility model.
The specific embodiment
The utility model provides a kind of LED fluorescent tube, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, referring to accompanying drawing examples, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
First in conjunction with Fig. 1, the overall structure of LED fluorescent tube provided by the utility model is elaborated, wherein, Fig. 1 is the preferred embodiment perspective view of a kind of LED fluorescent tube provided by the utility model.
As shown in Figure 1, described LED fluorescent tube comprises PC cover 101, heat-dissipating casing 102 and two lamp holders 103; Wherein, described PC cover 101 is connected with described heat-dissipating casing 102, and its concrete connected mode can be card and be connected or lock and connect;
Described lamp holder 103 is fastened on respectively the two ends after described PC cover 101 is connected with described heat-dissipating casing 102;
The utility model has designed the LED driving power that a kind of length is less than described lamp holder 103 length, and described LED driving power (not marking in the drawings) is arranged in two lamp holders 103 shown in Fig. 1 to the inside of any one; Because LED driving power being arranged on to the inside of lamp holder 103, make to go wrong need to change time when LED driving power, directly take off lamp holder 103 and change, and needn't dismantle the integral body of LED fluorescent tube, it is easy to maintenance easy to make, the expense of greatly having saved maintenance and repair.
Continuation is known with reference to Fig. 2, and the cross section of described PC cover 101 and described heat-dissipating casing 102 is all circular arc, and the central angle corresponding to circular arc of described PC cover cross section is greater than described heat-dissipating casing cross section;
Because heat-dissipating casing 102 needn't be used for holding LED driving power, and then reduced the size of heat-dissipating casing 102 cross-sectional areas, what make that the cross-sectional area of connected PC cover 101 can arrange is larger, and the transparent surface of LED fluorescent tube will be larger like this, thereby increased the light efficiency of LED fluorescent tube;
Preferably, to cover the corresponding central angle of circular arc of 101 cross sections be 240 degree to described PC; The corresponding central angle of circular arc of the cross section of described heat-dissipating casing 102 is 120 degree.
And in the situation that producing technique permission, the corresponding central angle of circular arc that also PC can be covered to cross section is 270 degree; The corresponding central angle of circular arc of the cross section of described heat-dissipating casing is 90 degree; Or other angles that are set to satisfy condition.
Known with further reference to Fig. 2, described heat-dissipating casing 102 comprises a substrate 122 and an arc 112, and described substrate 122 is integral type structure with described arc 112, and paster is provided with a plurality of LED lamp pearls 132 on described substrate 122.
Further, described heat-dissipating casing 102 is aluminium shell;
Further, described PC cover 101 is made by makrolon material.
In sum, LED fluorescent tube provided by the utility model, because LED driving power is arranged on to lamp holder inside, make heat-dissipating casing needn't hold LED driving power thereby can arrange less, and then increased the area occupied of PC cover, make the light-emitting area of fluorescent tube larger, and then there is higher light efficiency, thering is good illumination effect, and the input voltage of the applicable 90V to 265V of this LED fluorescent tube, can apply in the world, and power supply conversion efficiency is high, caloric value is low, meets user to energy-conservation demand, and then has good market.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
