Above-mentioned purpose of the present utility model is to realize by such technical scheme, it is a kind of LED plane decoration lamp: the shell that comprises printing opacity, the LED luminous tube, circuit board, cover plate, base is characterized in that: shell and dismountable cover plate by printing opacity constitute an airtight housing, and circuit board is fixed on the housing the inside; The luminous tube that is installed on the circuit board evenly distributes by luminescence unit, and to form homogeneous light emitting area, a luminescence unit can be the LED luminous tube of a monochrome or polychrome, also can be the luminous tube of several different colours; The ornament lamp housing is fixed on the support of base, makes and forms a space that is used to connect up between ornament lamp and base.

Said structure of the present utility model can further specify by a non-limiting square three look plane decoration lamp examples that accompanying drawing provides.

The utility model has following accompanying drawing:

Accompanying drawing 1:LED plane decoration lamp cross-sectional view;

2: three look planes of accompanying drawing lamp perspective view;

Accompanying drawing 3:LED luminous tube distribution schematic diagram.

Referring to accompanying drawing: LED plane decoration lamp: the shell 1 that comprises printing opacity, cover plate 2, LED luminous tube 3, circuit board 4, base 5, wherein: use an as close as possible red LED luminous tube 8 of spacing and a green LED luminous tube 9 as " luminescence unit " 10, luminous tube is that unit becomes matrix evenly arranged evenly with the luminescence unit, light emitting diode 3 is weldingly fixed on the circuit board 4, respectively with the luminous tube of different colours on the plate separately as one group, perhaps the luminous tube of every kind of color is divided into several groups, each group according to selected supply voltage

In luminous tube adopt and to be connected in series and in each group, to be connected in series current-limiting circuit (current-limiting circuit only is a resistance when powering with constant voltage dc source, employing during without the DC power supply of voltage stabilizing current-limiting circuit should be a simple constant-current circuit), then these the several groups drivings that are connected in parallel, lamp glows when the red luminotron on the plate is switched on, green light during the green luminotron energising, producing the photochromic of mixed light effect lamp when the red green luminous tube is switched on simultaneously is that open and close golden yellow, red, green luminous tube are controlled by external computer device or circuit; Shell 1 adopts the transparent plastic injection mo(u)lding of ageing resistance by ultraviolet light better performances, and inner face can be made into concavo-convex decorative pattern and not only can produce the light diffusion effect but also can increase attractive in appearance; Circuit board 4 is fixed on the cover plate 2, and cover plate is also used injection molding, and cover plate and shell adopt " coak " fixing, so that produce and take apart maintenance in batches; The base of ornament lamp has two kinds of functions: have support to make the space of reserving a wiring usefulness between ornament lamp and base on the base, to replace wiring groove, inner small and outside big embedding tenon is arranged at the bottom of base, so that directly adopt cement base is directly fixing on the wall as tiling, also has fixed screw holes on the base so that adopt common screw to fix, have on the shell of ornament lamp in this example " coak groove ", shell is fixed on the base by " coak " on the base support 7, dress, tear open very conveniently, the base in this example also adopts injection molding.
