Description
Technical field
The utility model relates to a kind of illuminating LED fluorescent tube, particularly a kind of can 360 ° of luminous LED annular lamp tubes.
Background technology
At present, general LED annular lamp tube is by glass endless tube, lamp holder and be arranged in this endless tube body corresponding annular base plate and some LED lamp pearls of minute being located in annular base plate form, and driving power is arranged on the lamp bracket of fluorescent tube outside in addition, and be electrically connected to LED lamp pearl by wire.It is compared with conventional fluorescent, has the more advantages such as energy-saving and environmental protection and life-span length.But because each LED lamp pearl in general LED annular lamp tube is all on a discrete face that is located at annular base plate in annular body, make this annular lamp tube can only 180 ° luminous, its illuminating effect be not ideal enough, and light mildness is not good enough, and light is inhomogeneous.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of improved LED annular lamp tube, makes the annular lamp tube can 360 ° of luminous, simple in structure, good illumination effect.
A kind of LED annular lamp tube described in the utility model, comprise that inwall scribbles the glass endless tube that expands light film, with the lamp holder of being located at this glass ring tube end, it is characterized in that: the LED filament that is provided with serial connection in described glass endless tube, with some inner supports, the LED filament of described serial connection is through each inner support centre bore, and the LED filament two ends of serial connection are connected with lamp holder.The LED filament of described serial connection is can 360 ° luminous, and wide-angle is luminous can bring better illuminating effect, and described inner support can be arranged in glass endless tube by positioning supports LED filament, simple in structure.Therefore, the utility model fluorescent tube is can 360 ° luminous, good illumination effect.
Preferably, in described lamp holder, be provided with driving power, can be more convenient while making to apply like this.
Preferably, described inner support is provided with three blades, and the outer end of each blade is provided with discount, and it is easy to use, and structure is simpler.
Useful technique effect of the present utility model is: by some inner supports, the LED filament of serial connection is arranged in glass endless tube, makes this LED annular lamp tube can 360 ° of luminous, simple in structure, good illumination effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is inner support front structure for amplifying schematic diagram in Fig. 1.
Fig. 3 is the sectional structure left view of Fig. 2.
The specific embodiment
Accompanying drawing mark explanation: 1-glass endless tube, 2-lamp holder, 3-LED filament, 4-inner support, 41-inner support centre bore, 42-blade.
As Figure 1-3, a kind of LED annular lamp tube, comprise that inwall scribbles the glass endless tube 1 that expands light film, with the lamp holder 2 of being located at this glass endless tube 1 end, in described glass endless tube 1, be provided with the LED filament 3 of serial connection, with some inner supports 4, the LED filament 3 of described serial connection is through each inner support centre bore 41, and LED filament 3 two ends of serial connection are connected with lamp holder 2.Described LED filament 3 is can 360 ° of full angles luminous, and wide-angle is luminous can bring better illuminating effect, and described inner support 4 positioning supports LED filaments 3 are arranged in glass endless tube 1, simple in structure.Therefore, the utility model LED annular lamp tube is can 360 ° luminous, good illumination effect.
In described lamp holder, can be provided with driving power, can be more convenient while making to apply like this.In addition also can be arranged in addition in a traditional way on the lamp bracket of fluorescent tube outside, during use, by wire, be electrically connected to LED lamp pearl.
Described inner support can be provided with three blades 42, and the outer end of each blade 42 is equipped with discount 43, and its structure is simpler, and described discount does not tiltedly move in the time of can making inner support be pushed in glass endless tube.
In the utility model glass endless tube 1, LED filament 3 two ends of serial connection are fixedly connected on respectively on respective end lamp holder 2, and lamp holder 2 is established passage routinely.In addition, described glass endless tube 1 two ends also can be designed to closing form, add man-hour after LED filament 3 two ends that are connected in series are fixedly connected with, then closed glass endless tube 1 two ends and vacuumizing, and then in glass endless tube 1, are filled with inert gas.Inert gas thermal conductivity is good, and the heating of LED filament can outwards be distributed by inert gas, glass endless tube successively like this, and radiating effect is better.
LED filament is that the series connection of a plurality of chips is fixed on glass substrate, then adopts fluorescent glue to carry out pressing mold to have encapsulated.LED filament has the high-tension characteristic of little electric current, has effectively reduced the heating of LED and the cost of driver, has outstanding photoelectric properties.The LED annular lamp tube that the LED filament of use serial connection forms can 360 ° of luminous, simple in structure, good illumination effect.
When inner support of the present utility model is installed, to first the LED filament of serial connection be passed to glass endless tube, then on the LED filament of serial connection, put inner support, make the LED filament of serial connection through inner support centre bore, inner support is pushed in glass endless tube again, the ring external diameter of inner support is all less than glass ring bore, and in glass endless tube, each adjacent inner support keeps a determining deviation.Like this, by using some inner supports that the LED filament of serial connection is arranged in glass endless tube.Make that annular lamp tube described in the utility model is can 360 ° luminous, simple in structure, good illumination effect, light evenly.
Should be understood that: above-described embodiment just illustrates of the present utility model, and the utility model is not limited to above-described embodiment, and any innovation and creation that do not exceed within the scope of the utility model connotation, within all falling into protection domain of the present utility model.
