Abstract
An offset-optical-axis LED tube is provided with a bracket with an inclined surface, an LED epistar body is fixed on the inclined surface of the bracket, the inclined angle between the inclined surface and the bottom surface of the bracket is 10 degrees to 15 degrees, an inclined hemispherical transparent light-concentrating shell is arranged outside the inclined bracket and the LED epistar body fixed thereon, and a cylindrical offset-optical-axis LED tube body is arranged below the hemispherical transparent light-concentrating shell. The utility model has the benefit that for a display screen or a signboard produced by employing the offset-optical-axis LED tube, a principal optical axis can point to the visual field of audience even through a screen is not inclined, so as to greatly improve the light energy utilization ratio of the display screen, or under the condition that certain viewing lightness is guaranteed, the driving current of the LED of the screen can be cut by nearly 50% and electrical energy is saved by half, accordingly, the service life of the offset-optical-axis LED tube is prolonged by more than two times since the service lives of the LED and the driving current are almost in inverse proportion relationship.
Description
Technical field
The utility model belongs to the LED luminescent device, particularly a kind of polarizing axis LED pipe.
Background technology
The application of LED luminescent device at present more and more widely, from indoor to outdoor; From direction board, signboard word to display screen; From the decorative lamp to the illuminating lamp.The LED luminescent device has spreaded all over the every nook and cranny of life.As direction board, signboard word or information display screen, generally usually be installed in eminence, look up for people and watch.At present the LED luminescent device of producing it sent only axisymmetric with the center of device, brought difficulty for so effective utilization of the LED luminescent device luminous energy in installation pinnacled direction board, signboard word or the information display screen.With the display screen is example, the display screen of hanging in height generally is not to tilt to install, and be perpendicular to floor mounted, the people watches at the ground lower, the display screen that is contained in eminence has only an oblique fire small part luminous energy earthward to be observed most of luminous energy by the people: direct light and on penetrate the light part, stand in ground people and can't see, therefore this part direct light and on penetrate light and all waste, inoperative.As if the efficiency of light energy utilization of wanting to improve screen, display screen need be tilted install, this not only brings difficulty to structure manufacturing and installation, but also influences whole visual effect, especially looks side ways when watching from the side of display screen, and the display screen body has the sense of inclination.Effect is bad.
The utility model content
Technical problem to be solved in the utility model is: a kind of polarizing axis LED pipe is provided.Address the above problem.
The technical solution of the utility model is:
A kind of polarizing axis LED pipe is characterized in that: tiltedly inclined to one side support of a surface is arranged, at the brilliant first body of the tiltedly inclined to one side surperficial fixed L ED of this support.
Gradient between the surface that support is tiltedly inclined to one side and the bottom surface of support is 10 °-15 °.
At oblique partially support and the external hemispherical transparent optically focused lamp housing that deflection is arranged of the brilliant unit of fixed L ED on it., be the polarizing axis LED body of cylinder below the hemispherical transparent optically focused lamp housing.
The utility model effect is: utilize the display screen or the sign board of this polarizing axis LED pipe manufacturer, under the situation that screen construction does not tilt, also can point to primary optical axis in spectators' FOV, greatly improve the efficiency of light energy utilization of display screen.In other words, under the certain situation of brightness, it is nearly 50% that the drive current of the LED of this screen can reduce, and also promptly can save electric energy 50%, because life-span and the inversely proportional approximately relation of drive current of LED, so the prolongation of such polarizing axis LED tube lifetime is more than 2 times.
Description of drawings
Fig. 1 is the structural representation of polarizing axis LED pipe
Fig. 2 is the structural representation that has the hemispherical transparent optically focused lamp housing polarizing axis LED pipe of deflection
Embodiment
A kind of as shown in Figure 1 polarizing axis LED pipe has tiltedly inclined to one side support 1 of a surface, at the brilliant first body 2 of the tiltedly inclined to one side surperficial fixed L ED of this support, the brilliant first body power supply lead wire 4 of LED is arranged on the tiltedly inclined to one side support bottom surface 3.
Gradient between the surface 5 that support is tiltedly inclined to one side and the bottom surface 3 of support is 10 °-15 °.
Above-mentioned is the polarizing axis LED pipe that a kind of product does not have the optically focused lamp housing.
The another kind of polarizing axis LED pipe of conduct as shown in Figure 2, the polarizing axis LED that has the optically focused lamp housing manages.It is oblique partially support 6 and on it brilliant first body of fixed L ED 7 outsides the hemispherical transparent optically focused lamp housing 8 of deflection is arranged.Being the polarizing axis LED body 9 of cylinder below the hemispherical transparent optically focused lamp housing, is lamp lead pin one 0 below the polarizing axis LED body of cylinder.
Claims (3)
1. a polarizing axis LED pipe is characterized in that: tiltedly inclined to one side support of a surface is arranged, at the brilliant first body of the tiltedly inclined to one side surperficial fixed L ED of this support.
2. polarizing axis LED pipe according to claim 1 is characterized in that: the gradient between the surface that support is tiltedly inclined to one side and the bottom surface of support is 10 °-15 °.
3. polarizing axis LED according to claim 1 and 2 pipe is characterized in that: at tiltedly support and the external hemispherical transparent optically focused lamp housing that deflection is arranged of the brilliant unit of fixed L ED on it partially, be the polarizing axis LED body of cylinder below the hemispherical transparent optically focused lamp housing.
