Preferably, described flat lamp also comprises: be arranged at the end of described many light-strips and the shading rubber belt between LED lamp bar, described shading rubber belt has the window that corresponding each described LED offers.

Preferably, the lateral surface of two light-strips that is provided with reflector plate between adjacent described many light-strips and is positioned at the outside is provided with reflector plate.

Preferably, the cross section of described light-strip is rectangle, triangle or parallelogram.

Preferably, the exiting surface of described light-strip has printing net-point.

Preferably, the quantity of described light-emitting diode light bar is two, and with the both side ends of described many light-strips, is oppositely arranged respectively.

In technical solutions of the utility model, because being arranged side by side, many light-strips form flat board, LED lamp bar is positioned at the end of described many light-strips and the plurality of LEDs of described LED lamp bar is distinguished relative with described many light-strip positions, controller is connected and controls described LED and light sequential with described LED lamp bars, therefore, can realize that monoplane multicolour band shows and color is chased, improve the mobility of color.

The specific embodiment

The purpose of this utility model is to provide a kind of flat lamp, the structural design of this flat lamp compared with prior art, many light-strips are arranged side by side and form flat board, LED lamp bar is positioned at the end of described many light-strips and the plurality of LEDs of described LED lamp bar is distinguished relative with described many light-strip positions, controller is connected and controls described LED and light sequential with described LED lamp bars, can realize that monoplane multicolour band shows and color is chased, improve the mobility of color.

As shown in Figure 1, the flat lamp that the utility model embodiment provides comprises: be arranged side by side and form dull and stereotyped many light-strips 13; Be positioned at the LED lamp bar 12 of the end of described many light-strips 13, described LED lamp bar 12 has the plurality of LEDs 12a relative with described many light-strip positions difference; With described LED lamp bar 12 signals, be connected and control the controller (not shown) that described LED12a lights sequential.

The light that LED12a sends enters respectively the relative light-strip 13 in position separately, makes flat lamp provided by the utility model realize that monoplane multicolour band shows.Controller (not shown) and LED lamp bar 12 signals are connected and control the sequential of lighting of LED12a, the described sequential of lighting is that LED12a sequentially lights successively or light at interval, at this, do not do restriction, thereby realized that the color of flat lamp chases, and then improved the mobility of color.

The flat lamp that the utility model as shown in Figures 2 and 3 provides, also comprise the diffusion sheet 10 that is arranged at a described dull and stereotyped side surface or both side surface.When a described dull and stereotyped side surface was provided with diffusion sheet 10, flat lamp only had a side display color; When two side planes of described flat board are respectively arranged with diffusion sheet 10, compared with prior art, the light that enters light-strip 13 sees through dull and stereotyped both side surface and then penetrates by diffusion sheet 10, the color that flat lamp is shown is softer, also make flat lamp realize double-sided display, improved the diversity of the color displays of planar LED lamp.

As shown in Figure 4 and Figure 5, the utility model LED flat lamp also comprises the end that is arranged at many light-strips 13 and the shading rubber belt 14 between LED lamp bar 12, described shading rubber belt 14 has the window that corresponding each described LED offers, adopt the light that the shading rubber belt of this structure can make the LED12a of LED lamp bar 12 send only to enter the light-strip 13 relative with the LED12a position, thereby effectively prevent the appearance of optical crosstalk situation between each adjacent light-strip 13.

As shown in Figure 6 and Figure 7, the lateral surface of two light-strips 13 that is provided with reflector plate 11 between adjacent described many light-strips 13 and is positioned at the outside is provided with reflector plate 11, after the light that LED12a sends enters light-strip 13, light is in light-strip 13 inscatterings, reflector plate 11 can go back to light-strip 13 inside by the light reflection of the adjacent light-strip 13 of the interior directive of light-strip 13, effectively prevents from the optical crosstalk situation occurring between each adjacent catheter bar 13.

As Fig. 8～shown in Figure 10, the cross section of light-strip 13 is rectangle, triangle or parallelogram, and the shape of cross section is not done restriction at this.

As shown in Figure 7, in embodiment of the present utility model, the exiting surface of light-strip 13 has printing net-point, and the printing net-point that has due to light-strip not only has refraction action to light, also has high reflex, therefore can improve brightness and the uniformity that flat lamp shows.

The utility model embodiment as shown in figure 11, the quantity of LED lamp bar 12 is two, and with the both side ends of described many light-strips 13, is oppositely arranged respectively.Not simultaneously, the LED flat lamp can have the more splendid color blending effect of color to the light color that the LED12a that is oppositely arranged with the both side ends of light-strip 13 enters light-strip 13.

Obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model also is intended to comprise these changes and modification interior.
