Abstract
The utility model relates to a high-brightness high-gray-level full-color LED (Light-Emitting Diode), which mainly solves the problems that the LED in the prior art is arranged to be totally dark, and therefore the contrast and the gray level are improved, but the brightness is reduced, and only a surface is arranged to be dark, and therefore the brightness is ensured, but the contrast and the gray level are reduced. The LED comprises a pin frame, wherein a light-shielding part provided with a light-reflecting cup in the middle is arranged on the surface of the pin frame, a light-emitting chip is arranged at the bottom of the light-reflecting cup, two black coatings are respectively arranged on the surface and the lateral surface of the light-shielding part, and a white or silvery-white coating is arranged on the surface of the light-reflecting cup. The high-brightness high-gray-level full-color LED has the advantages that not only is the displaying brightness of an LED display screen ensured, but also the gray level and the contrast are ensured.
Description
Technical field
The utility model relates to a kind of LED light-emitting diode field, especially relates to a kind of brightness that had both guaranteed that LED display showed, has guaranteed the highlighted high gray scale all-colour LED light-emitting diode of gray scale and contrast again.
Background technology
Tradition all-colour LED light-emitting diode or be complete black, promptly LED LED surface and side all are black, and the reflector surface also is a black, or is exactly LED LED surface silk-screen black ink, and the reflector surface is not a black.Wherein first kind of situation LED light-emitting diode is black entirely, though improved the contrast and the gray scale of LED display, but because reflector inside also is black, can absorb a large amount of light, thereby make the brightness meeting of LED display reduce 40%-60%, just complete black LED light-emitting diode has improved contrast and gray scale, has but reduced brightness.And second kind of situation, the reflector surface is not a black, though make LED display brightness not reduce, this LED light-emitting diode is only at surperficial silk-screen black ink, and all be white at side and breach, so just reduced LED display contrast of display degree and gray scale.As Granted publication number is CN201440309U, and name is called a kind of Chinese utility model patent of LED display module, and it includes substrate, external member, external member is installed the word substrate surface, have the hole on the external member, the hole wall of external member perforate is a black, and substrate is a black towards a side background color of external member.This patent changes the perforate hole wall into the black background color by original white background color, changes substrate into the black background color by original white background color, though improved contrast and gray scale, has had above-mentioned shortcoming, has reduced the brightness of LED display.
Summary of the invention
The utility model mainly is to solve in the prior art LED LED surface and the reflector back side all are arranged to black, though improved contrast and gray scale, but reduced the problem of brightness, a kind of brightness that had both guaranteed that LED display showed is provided, has guaranteed the highlighted high gray scale all-colour LED light-emitting diode of gray scale and contrast again.
Another goal of the invention of the present utility model is to have solved in the prior art only the LED LED surface to be arranged to black, though guaranteed LED display brightness, but reduced the problem of contrast and gray scale, a kind of brightness that had both guaranteed that LED display showed is provided, has guaranteed the highlighted high gray scale all-colour LED light-emitting diode of gray scale and contrast again.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of highlighted high gray scale all-colour LED light-emitting diode, comprise pin frame, on the pin frame surface, shading light part is set, the centre of shading light part is provided with reflective, bottom at reflector is provided with luminescence chip, is respectively arranged with black coating on the surface of described shading light part and the side.The utility model is all coated black coating in the surface and the side of shading light part, the surface and the side of shading light part are become black, make the LED light-emitting diode not influenced by external environment brightness like this, also improved simultaneously the contrast and the gray scale of LED display, guaranteed that the gradation of picture is clearly demarcated.Black coating is not coated on the surface of reflector, and it is a white or silvery white, makes reflector keep good reflective characteristic like this, and well the light of luminescence chip is dispersed in reflection, has guaranteed the brightness of LED display.This design of the present utility model had both guaranteed the brightness that LED display shows, had guaranteed gray scale and contrast again.
As a kind of preferred version, described pin frame bottom is connected with pedestal, and pedestal is connected with shading light part, and pin frame is folded between pedestal and the shading light part, is provided with pin at the pin frame two ends, and pin reveals to be put on the pedestal side.Pedestal and shading light part encapsulation have formed LED light-emitting diode integral body, and the pin frame two ends form pin, in order to be connected with external circuit.
As a kind of preferred version, the side of described pedestal is provided with black coating.The gray scale and the contrast of LED display have further been guaranteed.
As a kind of preferred version, described shading light part and pedestal are made by plastic material, and this plastic material is the PPA of white.This shading light part and pedestal have played insulating effect, prevent that adjacent LED light-emitting diode from directly disturbing, in addition, because the high-temperature stability of plastic material makes shading light part can well adapt to the hot environment in the luminescence chip course of work.
Therefore, the utility model has the advantages that: black coating is all coated in surface and side at shading light part, makes that the surface of shading light part and side are black, and the surface of reflector is a white or silvery white, both guarantee the brightness that LED display shows, guaranteed gray scale and contrast again.
