Description

Programmable all-colour LED lamp bar

[technical field]

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

[background technology]

LED possesses lot of advantages because of the optical characteristics of himself, its in service 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 chip or LED lamp are widely used in signal and show, play dynamic graphics and text, as information demonstration, advertising etc.The LED water pipe lamp is the linear decoration light fixture that is made of PVC ambroin, copper stranded conductor and series of LED lamp; And LED lamp band is a flat belt-like, generally by the led chip of evenly arranging on the FPC, encapsulates with transparent silica gel again.Advantages such as LED water pipe lamp or lamp band are ageing-resistant owing to having, antidetonation, safety, convenient transportation are applied in the illumination and decoration of bridge, river course guardrail landscape ornamental, viaduct, skin, indoor passage, door etc.Existing LED water pipe lamp, the unified employing of LED lamp band external control, color shows fixing, changes little.

[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 bar of performance are provided.

For achieving the above object, the utility model proposes a kind of programmable LED lamp bar, comprise FPC, programmable all-colour LED unit, PIN socket, transparent encapsulated layer; Described programmable all-colour LED unit is installed in parallel on described FPC, described PIN socket is arranged at described FPC end, described transparent encapsulated layer is coated on and becomes wire or band shape on each LED unit, the FPC, and described programmable LED unit comprises led chip, control circuit; Described led chip is electrically connected with described control circuit.

Described PIN socket has and draws power end, earth terminal, data input pin, the data output end that connects from described control circuit; Or have power end, earth terminal, a data terminal.

Above-mentioned programmable LED lamp bar, described led chip comprises red LED chip, green light LED chip, blue-light LED chip, the three is in parallel and be connected with described control circuit.Described red LED chip, green light LED chip, blue-light LED chip are uniformly distributed on the described FPC.

Above-mentioned programmable LED lamp bar also comprises watertight composition, is coated on the outer surface of described FPC, transparent silica gel encapsulated layer fully.

Owing to adopted above scheme, brought following beneficial effect:

LED lamp bar of the present utility model, be packaged with control circuit in the LED lamp, can directly drive respectively each LED lamp, also can unify to drive by external control circuit, it can realize full-color demonstration, can show various graph text informations, the range of application of LED lamp bar of the present utility model is expanded greatly, application performance is better.

LED lamp in the utility model is packaged in one by three kinds of led chips of red, green, blue, and is packaged with control circuit, 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 circuit of self by the external control device.
