Description
Technical field
The present invention relates to LED (Light Emitting Diode) lighting field combines with the culture and arts field, relate in particular to a kind of wireless mode that passes through, utilize the graceful moulding of constructing of LED and structure thereof itself, can display text (comprising three-dimensional literal) in floor light, the LED art lighting device of figure (comprising three-dimensional figure) and multicolour variation.
Background technology
In recent years, the illumination circle more and more pays close attention to the art design of illumination, the scientific and technological element in modern times, traditional culture and arts element are injected in the simple lighting device, to satisfy various special lighting demands such as Landscape Lighting, hotel lobby illumination, the illumination of the dwelling house hall.The illumination designer gives lighting device and not only has the most basic effect of illumination; But also wish that lighting device itself is an art work, itself has graceful moulding, the rich culture intension, the special culture background: or classic, or it is modern, or Chinese Elements, or ancient Roman's style, build ideal environment atmosphere, demonstrate noble elegant taste, with aesthetic requirement and the spiritual pursuit that satisfies the people inherence, for example utilize the LED art lighting device to realize Landscape Lighting, when building warm lighting environment, the The Analects of Confucius that can on lighting, show Confucius by lively and lovely literal, my Classic of the Virtue of the Tao, the perhaps locus classicus of the Holy Bible.
Also there are many inherent shortcomings at present in carrier (lighting device) as illumination art: or be exactly pure white-light illuminating, or be exactly the variation of pure color.These defectives have caused the luminal art limitation of design, and existing lighting device can't satisfy the increasing requirement that the illumination art proposes lighting.
Mainly there is the defective of following several respects in present lighting device:
1) the LED lighting is in illumination, demonstration that cannot be random two dimension or three-dimensional literal, pattern.The motion mode of the color of the font that cannot change irregularly at any time, font background color, font size, font shape, literal (can rotate, jump, scatter around light fixture etc.).
2) the LED lighting is in illumination, and the various moulding (for example Crystal lamp moulding) of (for example moulding of various lanterns, can be circular, cylindrical etc.) or ancient Roman's style are not also adopted and had the traditional cultural element of China in the design of its surface structure.
3) LED lighting also cannot be by the control signal of wireless mode (for example GPRS, GSM, RF) receiving computer or mobile phone issue, with the content of color, literal and the pattern of the brightness of control illumination, illumination.Particularly the color of lighting and brightness also cannot be sent by wireless mode after by computer programming: the change signal of several thousand kinds of colors; The variable signal of hundreds of kind brightness; The variable signal of tens kinds of lighting effects (the chasing of the change of color, the rotation of light, jump, flicker, color, flowing water, gradual change, saltus step, color flicker).
Summary of the invention
The present invention can not display image, literal or do not have an inconvenience of third dimension, not attractive in appearance and control signal transmission in order to solve in the prior art on the lighting device, the invention provides a kind of LED art lighting device, by single linearity or curve LED lamp bar, auxilliary plain conductor constitutes independently plane or curved surface shape LED luminescent layer; By a plurality of independently LED luminescent layers and LED illuminating layer, auxilliary indicative control unit constitutes LED art lighting device.Make lighting device can show various patterns and literal three-dimensionally, be used for Landscape Lighting and luminal art, and (wireless mode) controls graphic color and the brightness that lamp body will present in real time.
To achieve these goals, the light emitting diode illuminating apparatus that this patent provides, comprise: led lighting body, described led lighting body adopt LED lamp bar to constitute, and described LED lamp bar is to be welded on the printed circuit board (pcb) and to form by having the LED lamp; Indicative control unit is used to export control signal and lights described LED, makes to demonstrate corresponding literal, pattern, light coloring and lighting effects; Radio receiving unit is used to receive control signal, and the control signal that receives is delivered to indicative control unit.
Described LED lamp bar forms a plurality of luminescent layers (perhaps being light-emitting area) and illuminating layer, and each luminescent layer comprises a plurality of LED lamp bars, on each LED lamp bar a plurality of light emitting diodes is arranged; Nexine be by white led lamps (but being not limited to white led lamps) by being welded on the illuminating layer that forms on the printed circuit board, other layers are by being welded on the luminescent layer that forms on the printed circuit board by the red, green, blue three-color LED light.The described control signal of described indicative control unit output comprises red (R), green (G), blue (B) signal and row signal.
Described R signal, G signal and B signal in every group of control signal be with described LED lamp bar on corresponding red light pin, green light pin and blue lamp pin be in parallel.
The scan mode of R signal, G signal and B signal has determined the number of corresponding red light, green light and blue lamp that described R signal, G signal and B signal are connected described in each group control signal.
