Embodiment
The present invention is described in detail with reference to the accompanying drawings.
See figures.1.and.2 and be one embodiment of the present of invention synoptic diagram.Lamp box comprises the picture back up pad (not shown) that is arranged on lamp box displaying direction, and the light source of forming by plurality of LEDs 2 that is positioned at described picture back up pad rear, also comprise LED Drive and Control Circuit 3, link to each other, be used for controlling respectively the brightness of described plurality of LEDs with all led light source.Described plurality of LEDs can grid array be arranged, also can ring shooting, and the present invention does not limit this.
Decorate the field at some large-scale outside lights at present, such as building profile ornament lamp etc., some ripe controlling Design are arranged, the present invention combines the control technology of this respect with the LED drive controlling of lamp box, the LED Drive and Control Circuit can be according to the needs of bandwagon effect and design in advance, for example certain regional area (can be the advertised product LOGO that is showed) in whole image increases flicker effect, perhaps regularly changes some regional light and shade contrast etc.Because every LEDs can be controlled brightness separately, therefore, can realize a lot of bandwagon effects.
In addition, in order to increase integral illumination brightness, can also comprise a reflex reflector, as shown in Figure 1, reflex reflector is arranged in the lamp box, and reflex reflector is made up of the reflecting unit 1 of some adjacent settings, and reflecting unit 1 has the recessed spatial accommodation of opening towards described picture back up pad, the inside surface of spatial accommodation is reflective surface, and LED is arranged in the described spatial accommodation.In this example, adopting lighting angle is the LED 2 of 160 degree, in other embodiments, also can adopt the LED of other lighting angle as required, for example 120 degree.Described recessed spatial accommodation can be the recessed realization of end face by an awl terrace with edge or cylinder table shape, and the present invention does not limit this.
Specifically, reflex reflector can comprise the reflecting unit 1 of the inverted tetragonous cone table shape (also can be conical prismoid shapes such as triangular frustum, tetragonous cone table or pentagonal pyramid platform) that a plurality of peristomes edge interconnects.The inside surface of the reflecting unit of tetragonous cone table shape, promptly medial surface and bottom surface are reflective surface, and LED is arranged on the bottom surface or side of described reflecting unit symmetrically, and in this example, LED 2 is arranged on the axis of symmetry of reflecting unit inner bottom surface, as shown in Figure 2.
