Abstract
The utility model discloses an LED display module capable of emitting downward oblique light, which comprises a lamp panel, a plurality of LED lamps and a module cover; the LED lamps are mounted on the lamp panel at the same downward inclination angle; the module cover is arranged above the LED lamps; and an included angle theta is formed between the normal lines of each LED lamp and the lamp panel, ranging from 5 degrees to 25 degrees. As the LED lamps of the LED display module are arranged obliquely and downwardly, the module cover has a corresponding inclination angle, the LED display screen manufactured according to the LED display module has the characteristic of downward oblique light emission, the maximal luminous intensity can be effectively utilized, the effective utilization ratio of light of the display screen can be greatly improved, and meanwhile, as the display screen has a greater downward visual angle, the light pollution of the display screen is effectively reduced.
Description
Technical field
The utility model relates to a kind of LED and shows module, especially relates to a kind of lower luminous LED demonstration module that is tilted to.
Background technology
The light distribution characteristics of direct insertion oval LED lamp are: vertical direction changes very remarkable with the light intensity of the variation lamp at visual angle.During such as 25 ° in the vertical angle of view, the light intensity of lamp still has 50% of largest light intensity, and when the vertical angle of view was 30 °, light intensity then only had about 37% of largest light intensity.
At present the light source overwhelming majority that adopts of LED display is oval LED straight cutting lamp, its laying mode is that the LED lamp is vertical with lamp plate, and display screen is installed in often and uses on the certain altitude.Therefore owing to light source characteristics, pattern of lighting and mounting characteristics, so that such LED display has the following disadvantages:
1) because display screen is mounted in certain height, so the brightest light-emitting area of display screen can't be utilized, and effective utilization of LED light is lower;
2) the light distribution characteristics of elliptical lamp are so that the vertical visual brightness reduction of display screen is very fast, and so, display screen watches visual brightness larger, and the normal light intensity requirement of lamp is higher, thereby cause that power consumption increases, heat increases, the problem of the life-span reduction of lamp;
3) can't effectively utilize owing to the brightest light and light above the horizon, and then can cause the light pollution problem.
The utility model content
The light utilization efficiency that exists for existing LED display is low, the vertical angle of view is little, the light pollution problem, the utility model provide a kind of can Effective Raise LED display light utilization efficiency, increase the vertical downwards angle of visibility of LED display, reduce LED luminous under being tilted to of light pollution and show module.
The utility model adopts following technical scheme to realize: a kind ofly be tilted to lower luminous LED and show module, it comprises: lamp plate; Be installed in some LED lamps on the lamp plate with identical downtilt angles; Be arranged on the module face shield of LED lamp top.
Wherein, become angle theta between the normal of each LED lamp and lamp plate, and 5 °≤θ≤25 °.
Wherein, at the module face shield lamp position hole that several and LED lamp are complementary is set.
Wherein, the angle theta between the normal of each lamp position hole and lamp plate, and 5 °≤θ≤25 °.
Wherein, the some thes brim of a hat that arrange on the module face shield.
Wherein, the angle theta between the normal of each the brim of a hat and lamp plate, and 5 °≤θ≤25 °.
Compared with prior art, the utlity model has following beneficial effect:
For the vertical LED that lays of present straight cutting LED lamp shows module, because LED of the present utility model shows that the LED lamp of module is downward-sloping laying, the module face shield has corresponding angle of inclination, so show the LED display that module obtains by this utility model LED, have and be tilted to lower luminous characteristic, its maximum emission intensity can be used effectively, the effective rate of utilization of display screen light can greatly improve, simultaneously, display screen has larger downwards angle of visibility, and the light pollution of display screen is effectively reduced.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the part side schematic view of Fig. 1.
Embodiment
In conjunction with illustrated in figures 1 and 2, the utility model provide a kind of can Effective Raise the LED display light utilization efficiency, increase the vertical downwards angle of visibility of LED display, reduce LED luminous under being tilted to of light pollution and show module, it comprises: lamp plate 1, be installed in some LED lamps 2 on the lamp plate 1, be arranged on the module face shield 3 of LED lamp 2 tops.
Wherein, each LED lamp 2 is installed on the lamp plate 1 with identical downtilt angles, with the example that is characterized as of certain LED lamp, becomes the angle of θ between the normal of LED lamp 2 and lamp plate 1, then 5 °≤θ≤25 °.
In addition, the lamp position hole that several and LED lamp 2 are complementary is set on the module face shield 3, each lamp position hole has the downtilt angles identical with LED lamp 2, also becomes the angle of θ between the normal of each lamp position hole and lamp plate 1, then 5 °≤θ≤25 °.And the some thes brim of a hat 31 that arrange on the module face shield 3 also have downward-sloping feature, the downward-sloping angles of the brim of a hat 31 for and the normal of lamp plate 1 between the angle that forms be 5 °～25 °.
Therefore, for the vertical LED that lays of present straight cutting LED lamp shows module, because LED of the present utility model shows that the LED lamp of module is downward-sloping laying, the module face shield has corresponding angle of inclination, so show the LED display that module obtains by this utility model LED, have and be tilted to lower luminous characteristic, its maximum emission intensity can be used effectively, the effective rate of utilization of display screen light can greatly improve, simultaneously, display screen has larger downwards angle of visibility, and the light pollution of display screen is effectively reduced.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
