Description

Programmable all-colour LED lamp

[technical field]

The utility model relates to a kind of encapsulating structure of LED lamp.

[background technology]

LED possesses lot of advantages because of the optical characteristics of himself, its in useful life overlength, power consumption is extremely low owing to belong to cold light source, fire safety does not have any noise, no ultraviolet radiation, so obtain more and more widely application.Present stage, LED is widely used in signal and shows, play dynamic graphics and text, as information demonstration, advertising etc., under this kind purposes, the LED element that quantity does not wait is built into array, adopt controller to carry out matrix control, each LED element is a pixel, and each pixel adopts a kind of LED lamp of fixedly glow color, therefore specific to each pixel, it only can control the switch of this point, and can not control its color change, so the graph text information of whole LED display screen broadcast, its color is dull, and appreciation effect is relatively poor.

[summary of the invention]

Main purpose of the present utility model is: a kind of rich color, applying flexible, the better programmable all-colour LED lamp of performance are provided.

For achieving the above object, the utility model proposes a kind of programmable all-colour LED lamp, comprise led chip, control IC plate, pin, housing; Described control IC plate is provided with and is used to drive the luminous control IC of described led chip; Described led chip is affixed with described control IC plate and be electrically connected with described control IC; Described led chip, control IC plate are packaged in the described housing; Described pin directly or indirectly draws from described control IC plate and picks out outside the described housing.

Described pin comprises supply pin, grounding leg, data input pin, data output pin.

Above-mentioned programmable all-colour LED lamp also comprises substrate, and described led chip is arranged at described upper surface of base plate, and described control IC plate is arranged at the lower surface of described substrate; Led chip on described substrate and the substrate, control IC plate are packaged in the described housing; Described pin from described substrate or/and draw the control IC plate and pick out outside the described housing.

Above-mentioned programmable all-colour LED lamp, described housing comprises the housing base, is filled with insulating heat-conductive glue between described housing base and described control IC plate, the substrate.

Above-mentioned programmable all-colour LED lamp, described led chip comprises red LED chip, green light LED chip, blue-light LED chip.Described red LED chip, green light LED chip, blue-light LED chip are uniformly distributed in the upper surface of described substrate.

Because adopted above scheme, the utility model has brought following beneficial effect:

LED lamp of the present utility model is packaged with control IC, and compact conformation self just can be realized showing control, and display color, display timing generator all can be controlled automatically; And can control it, or load the renewal control program in the control IC of self by the external control device; Be packaged in one by red, blue, green three kinds of led chips, it realizes full-color demonstration by the built-in control circuit may command; When adopting LED lamp of the present utility model to form display matrix, as a pixel, it can realize full-color demonstration, therefore, LED displays compared to prior art etc., the graph text information of its demonstration can be completely achieved full color and show that display effect obtains qualitative leap; Because self full-color demonstration and programmable are expanded the range of application of LED lamp of the present utility model greatly, application performance is better.
