The LED lamp tube also comprises a support fixedly arranged in the casing; the LED light source is arranged on the support uniformly; the support is provided with an inner cavity for accommodating the driving power supply. According to the LED lamp tube disclosed by the utility model, the driving power supply does not need to be arranged at a lamp holder. Compared with the relation that LED lamp beads and the driving power supply are parallel in position in the prior art, the LED lamp beads and the driving power supply are stacked, the occupied installation position of the LED lamp beads is reduced, and the luminous range of the LED lamp tube is increased. The surface area of the support is increased, the heat dissipation effect is better, the LED junction temperature is reduced, and the service life of the LED lamp tube is prolonged. The cross sectional area of the support is increased, and the LED lamp tube has higher rigidity, and is unlikely to bend or deform. The plastic casing has good fireproof and electrical shock protection effects, and the use is more secure.

LED fluorescent tube is widely used.In general LED fluorescent tube, its driving power is all mounted in the lamp holder at two ends, has taken certain position.LED fluorescent tube is wanted replace fluorescent lamps pipe, and the length of LED fluorescent tube just need to meet relevant criterion, and therefore driving power is arranged on the position that has taken in fact LED lamp pearl in lamp holder, has reduced the light emitting region of LED fluorescent tube.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, and a kind of LED fluorescent tube is provided, and to reduce the taking of LED lamp pearl installation site, increases the light emitting region of LED fluorescent tube.
For achieving the above object, the utility model is by the following technical solutions:
A kind of LED fluorescent tube, comprise housing, be located at the LED light source in housing and be used to LED light source that the driving power of electric energy is provided, LED fluorescent tube also comprises the support being fixed within housing, and LED light source is evenly laid on support, and support is provided with the inner chamber for placing driving power.
Further, support comprises top board and semi-cylindrical shaped sidewall, and inner chamber is surrounded by top board and sidewall.The cross section of support is closed semicircle, compared to existing technology, be similar to the support of slab, the support of this closed semi-circular cross-section has increased the cross-sectional area of support, therefore the rigidity of support is improved, thereby the rigidity of LED fluorescent tube is just due for promotion mutually, can make whole LED fluorescent tube be difficult for flexural deformation.Meanwhile, after support volume increases, the ability of its heat radiation is improved, and has reduced the junction temperature of LED fluorescent tube, has improved the life-span of LED fluorescent tube.
Further, the inwall of housing is close in the outside of sidewall, and the object first of this structure is in order more effectively to dispel the heat to the external world, and it two is the rigidity that promotes better LED fluorescent tube.
Further, LED light source is evenly laid in the outside of top board.
Further, the mounting groove that the outside of top board is provided with, LED light source comprises aluminium base and is fixed on the LED lamp pearl of aluminium base, and aluminium base is fixed in mounting groove, and LED lamp pearl is towards the outside of top board.
Further, the sidewall upper of mounting groove is provided with the flanging for fixing aluminium base, and aluminium base can insert in mounting groove from one end of mounting groove, clamps aluminium base by flanging from top, can more easily realize the fixing of aluminium base.
Further, housing comprises tubular lampshade and is fixed on the lamp holder at lampshade two ends, and LED light source and driving power are located in the space that lampshade and lamp holder surround.
Further, the inwall of lampshade is provided with the blend stop for support bracket fastened position, and support is resisted against blend stop below.
Further, lampshade is monochromatic light modulation cover or the double-colored lampshades of expanding of plastics.
Further, support is aluminium cooling stand.
Further, housing is fireproof plastic casing.Plastic casing can play good fire prevention and electrocution-proof protection effect, uses safer.
The utility model beneficial effect is compared with prior art:
The support of the utility model LED fluorescent tube arranges inner chamber, driving power is installed in inner chamber, driving power does not need to be arranged on lamp holder, be that position relationship arranged side by side is different from LED lamp pearl and driving power in prior art, LED lamp pearl of the present utility model and driving power are stacked position relationship, thereby reduced the taking of LED lamp pearl installation site, increase the light emitting region of LED fluorescent tube.
