Abstract
The utility model discloses a wide-angle LED (Light Emitting Diode) fluorescent lamp tube which comprises a heat radiating base, wherein a transparent protective cover is covered on the heat radiating base and is internally provided with an LED light source fixedly mounted on the heat radiating base, the transparent protective cover and the heat radiating base are spliced to form a lamp tube with a circular section, the coverage angle of the transparent protective cover above the lamp tube exceeds 180 degrees, the LED light source is positioned below the circle center of the lamp tube, and an aluminum substrate with a certain thickness is arranged between the LED light source and the heat radiating base. The coverage angle of the transparent protective cover above the lamp tube exceeds 180 degrees, the LED light source is positioned below the circle center of the lamp tube, and the LED light source is raised by the aluminum substrate with a certain thickness, so that the shielding of the heat radiating base to light rays of the LED light source is reduced, and the light rays of the LED light source can irradiate outside at an angle which is more than or equal to the coverage angle of the transparent protective cover, thereby ensuring that the illuminating angle of the lamp tube exceeds 180 degrees.
Description
Technical field
The utility model relates to a kind of fluorescent tube, particularly a kind of Wide-angle LED fluorescent tube.
Background technology
As everyone knows, the light efficiency of LED lamp improves day by day, its cost is relatively cheap, the trend that the LED lamp replaces conventional incandescent, fluorescent lamp, mercury vapor lamp, Halogen lamp LED and fluorescent type electricity-saving lamp is day by day obvious, therefore on the market many LED fluorescent tubes have been arranged, but the light angle of present most LED fluorescent tubes is being below 180 ° all, this has caused the LED fluorescent tube can not shine ceiling under many circumstances, thereby cause ceiling to be dark shape, do not satisfy people's life requirement.
The utility model content
In order to address the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, and can make again its light angle surpass 180 ° Wide-angle LED fluorescent tube.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of Wide-angle LED fluorescent tube; comprise heat dissipation base; the heat dissipation base upper cover is connected to light permeable protection; be provided with the led light source that is fixedly mounted on the heat dissipation base in the light permeable protection; it is circular fluorescent tube that described light permeable protection and heat dissipation base splicing form a cross section; the angle that light permeable protection covers fluorescent tube surpasses more than 180 °; led light source is being provided with certain thickness aluminium base below the fluorescent tube center of circle and between led light source and the heat dissipation base; the angle that above-mentioned light permeable protection covers fluorescent tube surpasses the below that 180 ° and led light source are positioned at the fluorescent tube center of circle; certain thickness aluminium base bed hedgehopping has been arranged simultaneously led light source; reduced heat dissipation base blocking the light of led light source; so that the light of led light source can with more than or equal to angular illumination that light permeable protection was covered in the external world, thereby so that the light angle of fluorescent tube above 180 °.
Further; the cross section of described light permeable protection is that a circular arc and circular arc two ends are respectively arranged with a projection; the both sides of heat dissipation base are respectively arranged with the recess that cooperates interlocking with projection, and above-mentioned projection and recess have made things convenient for the installation of light permeable protection and heat dissipation base.
The beneficial effects of the utility model are: because the utility model is the structure of circular fluorescent tube by adopting the splicing of light permeable protection and heat dissipation base to form a cross section; the angle of fluorescent tube that light permeable protection covers surpasses the below that 180 ° and led light source are positioned at the fluorescent tube center of circle; simultaneously by certain thickness aluminium base bed hedgehopping has been arranged led light source; increase the distance between led light source and the heat dissipation base; reduced heat dissipation base blocking led light source light; so that the light of led light source can be with the angular illumination that covers more than or equal to light permeable protection in the external world; thereby so that light angle of the present utility model is greater than 180 °; be respectively arranged with projection and the recess that cooperatively interacts and install on light permeable protection and the heat dissipation base simultaneously; made things convenient for the installation of light permeable protection and heat dissipation base; in addition; be provided with aluminium base between led light source and the heat dissipation base and can accelerate the radiating rate of led light source, guaranteed the radiating effect of fluorescent tube.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the part drawing of light permeable protection in the utility model;
Fig. 3 is the part drawing of heat dissipation base in the utility model.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of Wide-angle LED fluorescent tube, at first process heat dissipation base 1 of the present utility model, then process respectively recess 10 in the both sides of heat dissipation base 1, the above-mentioned heat dissipation base 1 preferential aluminium extruded type that adopts adopts plastic cement or heat conduction plastic cement also passable certainly.
Further; process the light permeable protection 2 of arc; and process respectively a projection 20 that can match and install with recess 10 in two ends of light permeable protection 2, above-mentioned light permeable protection 2 preferentially is processed into the arcuation protective cover that arc angle surpasses 180 °.
Further; processed certain thickness aluminium base 5; then aluminium base 5 is fixedly mounted on the centre position of the upper surface of heat dissipation base; then led light source 3 is fixedly mounted on the aluminium base 5 again; projection 20 with light permeable protection 2 two ends imbeds respectively in the recess 10 of heat dissipation base 1 both sides at last; thereby be installed on the heat dissipation base 1 so that light permeable protection 2 covers connect, form fluorescent tube 4 of the present utility model, above-mentioned led light source 3 is positioned at the below in fluorescent tube 4 centers of circle.
The above only is preferential embodiment of the present utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the present utility model.
