Problems solved by technology

Due to the characteristics of the LED itself, it is determined that its light has a certain beam angle, so the light is different at different light angles. For the LED light tube, the distribution of light along the circumference of the light tube is not uniform. After the existing LED light tube is installed , the light emitting direction of the light is fixed, so the light emitting direction of the general lamp tube gradually decreases from the middle to the two sides, which is difficult to meet the actual use needs

Embodiment 1

[0027] Such as Figure 1 to Figure 6 As shown, the rotatable LED fluorescent tube of this embodiment includes a tubular lamp body 3, the tubular lamp body 3 is provided with a light source board assembly 2 with LEDs inside, and the rotatable LED fluorescent tube also includes two lamp cap holders 4 and two rotating bases 6, the lamp base fixing base 4 has a lamp base 5 and is fixed with the lamp holder 9 through the lamp base 5, and the two ends of the tubular lamp body 3 are fixedly connected with the rotating base 6, The rotating base 6 is connected to the lamp holder 4 in rotation so as to change the light emitting direction of the light source board assembly 2; specifically, the lamp holder 4 includes an annular side wall 41, two and The annular side wall 41 has protruding posts 42 extending in the same direction. Of course, there may be multiple protruding posts 42. The front ends of the protruding posts 42 are provided with hooks 43. The rotating base 6 includes a bottom...

Embodiment 2

[0029] Such as figure 1 , figure 2 with Figure 7 As shown, the difference between the rotatable LED fluorescent tube of this embodiment and Embodiment 1 is that: in this embodiment, the cross-section of the heat dissipation profile 1 is square, and at the same time, the light source board assembly 2 has four pieces parallel to each other. They are respectively arranged on all four surfaces of the heat dissipation profile 1, and the numbers of the screw holes 10, the ribs 11, and the slots 12 all change accordingly with the number of sides of the heat dissipation profile 1 for four.

[0030] The remaining features of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0032] Such as figure 1 , figure 2 with Figure 8As shown, the difference between the rotatable LED fluorescent tube of this embodiment and the first embodiment is: the tubular lamp body 3, in this embodiment, the tubular lamp body 3 includes semi-circular Columnar light output cover 38 and heat dissipation housing 39, the light source board assembly 2 is plugged on the light output cover 38, the insulation effect is good, the creepage distance requirement is met, and the disadvantages caused by being installed on the heat dissipation housing 39 are avoided. The end of the heat dissipation housing 39 is provided with two fixing holes 15, and the rotating base 6 is provided with two through holes 60, and two screws 7 pass through the through holes 60 and are connected to the fixing holes 15. connected so that the tubular lamp body 3 is fixed to the rotating seat 6, a cavity 9 is formed between the heat dissipation housing 39 and the light source board assembly 2, and a drivi...

Abstract

The invention discloses a rotary LED (Light-Emitting Diode) fluorescent lamp tube which has simple structure and is convenient to regulate. The rotary LED fluorescent lamp tube comprises a tubular lamp body (3), two lamp cap fixing seats (4) and two rotary seats (6), wherein a light source board assembly (2) with a LED is arranged in the tubular lamp body (3); the lamp cap fixing seats (4) are provided with lamp caps (5) and are fixed together with a lamp holder (9) by the lamp caps (5); both ends of the tubular lamp body (3) are fixedly connected with the rotary seats (6); the rotary seats (6) are rotationally connected with the lamp cap fixing seats (4) so as to change the light emitting direction of the light source board assembly (2). The rotary LED fluorescent lamp tube can be widely applied to the field of a LED lamp.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a rotatable LED fluorescent lamp tube. Background technique [0002] LED has the advantages of high luminous efficiency, power saving and long life, and its application is more and more extensive. LED light tubes have also emerged as the times require instead of traditional fluorescent tubes for daily lighting. Due to the characteristics of the LED itself, it is determined that its light has a certain beam angle, so the light is different at different light angles. For the LED light tube, the distribution of light along the circumference of the light tube is not uniform. After the installation of the existing LED light tube , the light emitting direction of the light is fixed, so the light emitting direction of the general lamp tube gradually decreases from the middle to the two sides, which is difficult to meet the actual use needs. If the lamp tube can be rotated, the illumination in different ...
