Lamp bar using bent pin LED lamp declination and display screen

Abstract

The invention provides a lamp bar using bent pin LED lamp declination and a display screen. The lamp bar comprises a lamp bar PCB provided with a plurality of LED lamps and a circuit connector, the lamp bar PCB is provided with at least one circuit connector capable of being connected with a stand column PCB, all the LED lamps are vertically inserted and welded to the lamp bar PCB, and pins of the LED lamps are bent in the same direction, so that when the circuit connector is connected with the stand column PCB, an include angle alpha is formed between the light-emitting end faces or extending faces of the LED lamps and the plane or extending face of the stand column PCB, and alpha is larger than 0 degree and smaller than 90 degrees. The maximum light intensity angles of the LED lamps of the lamp bar incline downwards, the impression brightness of the display screen installed at a high position is improved, and therefore the energy saving effect of the display screen is improved. The lamp bar can be narrowed easily, and the permeable rate is increased. The improvement cost is low, the risks are small, the structure is simple, and manufacturing and maintenance are easy.

Description

technical field [0001] The present invention relates to a light bar using bent-leg LED lamps, in particular to a structure of a light bar using bent-leg LED lights and a display screen formed therefrom. Background technique [0002] figure 1 It is a typical light distribution curve (i.e. light intensity distribution curve) of LED lamps, see figure 1 , it can be known that the relative light intensity in the 0° direction of the light distribution curve (that is, the normal direction of the light-emitting end face) is the largest, which is 100%. In the currently used light bar display, the direction of the maximum light intensity of the chip in the LED component is perpendicular to the wall on which the display is installed (that is, in a horizontal direction). Since the display screens are mostly installed in high places, if the figure 1 For example, when people look up, the relative light intensity is 55.3% when looking up at 30°, and 33% when looking up at 45°. The large...

Problems solved by technology

Although this can make the direction of the maximum relative light intensity decline to increase the downward brightness of the light bar, but because the light bar and the vertical adapter plate are inserted and connected at the side, only multiple light bars can only be inserted into the longitudinal adapter plate on one side during installation. After completion, the vertical adapter plate on the other side can only be installed, so the installation is difficult; it is also difficult to repair and replace the faulty light bar; and there is still room for further improvement in the air permeability of the display screen with such a structure

[0008] From the typical patents cited above, it can be seen that technicians in this industry try their best to solve the problem of the downward tilt of the LED lights in the light bar display, so as to improve the perceived brightness of the LED display installed at a high place; the technicians also try their best to improve The light bar display has high air permeability, simple structure, and easy manufacture and maintenance; the first three patents are improved from the LED light, and the last two patents are improved from the installation structure of the light bar display, but they all bring new Problems or room for further improvement
