Description
Technical field
The utility model relates to the large LED fluorescent lamp tube of a kind of light distribution angle, belongs to lighting field.
Background technology
Existing fluorescent tube illumination unevenness, light distribution angle are less than normal, and circuit board are provided with multiple LED, and caloric value is large, and existing fluorescent tube ubiquity dispels the heat bad phenomenon, and service life shortens greatly.
Utility model content
The purpose of this utility model overcomes the defect that prior art exists, and provides that a kind of maintaining uniform illumination, light distribution angle are large, the LED fluorescent lamp tube of good heat dissipation effect.
The utility model solves the technical scheme that its technical problem adopts: the LED fluorescent lamp tube that a kind of light distribution angle is large, comprise base, transparent lamp shade, support, circuit board and LED, described base is fixedly connected with transparent lamp shade, described base is provided with support, described circuit board is connected on support, and the front of described circuit board is provided with some LED, and described each LED is all covered with lens, described circuit board is arranged in " eight " word, and the reverse side of described circuit board is provided with radiating fin.
Described base is fixed with fixed head, and these fixed head two ends are protruding, and described transparent lamp shade both sides are equipped with hook, and described hook is articulated on fixed head two ends; Thermal insulation board is provided with in described fixed head.
Described support is provided with draw-in groove, and described circuit board two ends are connected in draw-in groove.
Beneficial effect: (one) increases lens in LED, makes light distribution angle be greater than 120 °;
(2) circuit board adopts "eight" shape structure, makes maintaining uniform illumination;
(3) radiating fin is set at circuit board reverse side, greatly improves radiating effect, prolong
Grow service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Detailed description of the invention
The LED fluorescent lamp tube that a kind of light distribution angle is as shown in Figure 1 large, comprises base 1, transparent lamp shade 2, support 3, circuit board 5 and LED 6.Described base 1 is fixedly connected with transparent lamp shade 2, detailed description of the invention: described base 1 is fixed with fixed head 7, and these fixed head 7 two ends are protruding, and transparent lamp shade 2 both sides are equipped with hook 8, and hook 8 is articulated on fixed head 7 two ends.Thermal insulation board 9 is provided with in described fixed head 7.
Described fixed head 7 is provided with support 3, and support 3 is provided with draw-in groove 4, and circuit board 5 two ends are connected in draw-in groove 4.The front of circuit board 5 is provided with some LED 6, and each LED 6 is all covered with lens 10, and circuit board 5 is arranged in " eight " word, and the reverse side of described circuit board 5 is provided with radiating fin.
During use, due to the protruding base 1 in fixed head 7 two ends, transparent lamp shade 2 both sides are provided with hook 8, the hook 8 of transparent lamp shade 2 both sides is articulated on the fixed head 7 of base 1 both sides, base 1 is fixedly connected with transparent lamp shade 2, support 3 is provided with, so that fixing in the draw-in groove 4 of circuit board 5 inlay card on support 3 in base 1.When LED lamp tube switches on power, when the LED 6 on circuit board 5 is started working, the heat given out by radiating fin 51 and thermal insulation board 9 Quick diffusing, will extend the service life of LED lamp tube.
Should be appreciated that specific embodiment described above only for explaining the utility model, and be not used in restriction the utility model.Still be among protection domain of the present utility model by spirit institute's apparent change of extending out of the present utility model or change.
