Abstract
The utility model provides an LED lamp tube which comprises a tubular lamp body, a first lamp tube holder, a second lamp tube holder, a bar-shaped substrate and an LED light source distributed in bar-shaped distribution. The first lamp tube holder and the second lamp tube holder are fixedly connected to two ends of the lamp body respectively. The bar-shaped substrate and the LED light source are arranged in the lamp body. The lamp body comprises a diffusion cover and a heat radiator which are fastened to each other. The LED light source is fixedly connected to the substrate, and the substrate is fixedly connected to the heat radiator. The diffusion cover comprises a main diffusion side and an auxiliary diffusion side, and the main diffusion side is planar. The LED lamp tube has the advantages that the main planar diffusion side of the diffusion cover is luminous unidirectionally, so that light outlet angle is narrowed, and fewer light rays are shielded, and efficiency of the LED lamp tube is improved. Meanwhile, even if multiple LED lamp tubes are used together, light shield among the lamp tubes can be reduced, and efficiency can be improved greatly.
Description
Technical field
The utility model relates to the LED technical field, particularly a kind of LED fluorescent tube.
Background technology
For lighting field, former general be fluorescent tube, that widelys popularize application now is the LED fluorescent tube.
Existing LED fluorescent tube is circular lamp body, and promptly its cross section is circular, and the cross section of its corresponding diffusion shell is circular-arc, and therefore, the rising angle of this kind LED fluorescent tube is bigger.When many fluorescent tubes were installed on the same light fixture side by side, the light that arbitrary fluorescent tube sends received blocking of other fluorescent tube or light fixture easily, thereby caused light loss, so existing its efficient of LED fluorescent tube is low.
The utility model content
In order to solve above-mentioned existing technical problem, the utility model provides a kind of LED fluorescent tube, and the main diffusion face of its diffusion shell is the plane, and is unidirection luminous, dwindling rising angle, to reduce light and be blocked, thereby improves its efficient.
The utility model solves above-mentioned existing technical problem; A kind of LED fluorescent tube is provided; It comprises the lamp body of strip, is fixedly connected on first lamp holder and second lamp holder at said lamp body two ends respectively, is arranged at the led light source that an inner strip substrate of said lamp body and a strip distribute; Said lamp body comprises the diffusion shell and the radiator of mutual fastening; Said led light source is fixedly connected on said substrate, and said substrate is fixedly connected on said radiator; Said diffusion shell comprises main diffusion face and side diffusingsurface, and said main diffusion face is the plane.
The utility model improvement further is described below.
Said side diffusingsurface is the plane.
Said side diffusingsurface is a curved surface.
Said radiator has a strip boss, and said substrate correspondence is arranged at said boss.
Said boss has a strip mounting groove, and said substrate correspondence is embedded in said mounting groove.
Compared to prior art, the beneficial effect of the utility model is: the main diffusion face of diffusion shell is the plane, and is unidirection luminous, dwindling rising angle, to reduce light and be blocked, thereby improves its efficient.Simultaneously, even many LED fluorescent tubes use side by side, also can reduce the light occlusion issue between the fluorescent tube, thereby significantly raise the efficiency.
Description of drawings
Fig. 1 is the decomposing schematic representation of the utility model LED fluorescent tube.
Fig. 2 is the schematic cross-section of said LED fluorescent tube.
Fig. 3 is installed in the structural representation on the light fixture for many said LED fluorescent tubes.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
Extremely shown in Figure 3 like Fig. 1, a kind of LED fluorescent tube 100, it comprises the lamp body of strip, is fixedly connected on first lamp holder 121 and second lamp holder 122 at lamp body two ends respectively, is arranged at the led light source 114 that an inner strip substrate 113 of lamp body and a strip distribute; Lamp body comprises the diffusion shell 112 and radiator 111 of mutual fastening, and diffusion shell 112 is used for bright dipping, and radiator 111 is used to solve led light source 114 heat dissipation problem when luminous; Led light source 114 is fixedly connected on substrate 113, and substrate 113 is fixedly connected on radiator 111; Diffusion shell 112 comprises main diffusion face 1121 and side diffusingsurface 1122, and main diffusion face 1121 is the plane.When this LED fluorescent tube 100 is installed on the supporting light fixture 200, and provide after the electric energy, through first lamp holder 121 and/or 122 energisings of second lamp holder, substrate 113 energisings, the led light source 114 that is electrically connected at substrate 113 like this is promptly luminous, realizes the illumination of LED fluorescent tube 100.The main diffusion face 1121 of these LED fluorescent tube 100 diffusion shells 112 is the plane, and is unidirection luminous, dwindling rising angle, to reduce light and be blocked, thereby improves its efficient.Simultaneously, even many LED fluorescent tubes 100 use side by side, each the main diffusion face 1121 after it is arranged side by side forms a plane, also can reduce the light occlusion issue between the fluorescent tube, thereby significantly raise the efficiency.
The utility model side diffusingsurface 1122 is the plane, perhaps is curved surface, because main diffusion face is 1121 unidirection luminous, rising angle is little, so even side diffusingsurface 1122 has a small amount of shading phenomenon, also integral body has improved efficient.
For the ease of the installation of substrate 113, radiator 111 has a strip boss 1111, and substrate 113 correspondences are arranged at boss 1111; Preferably, these boss 1111 correspondences have a strip mounting groove, and substrate 113 correspondences are embedded in mounting groove.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
