Abstract

The utility model relates to an energy-saving light box picture of changing light colors, which is composed of a framework, a picture, super-lightness LED arrays, a single chip control and driving circuit, a power supply, a bottom plate, etc. The utility model enables the super-lightness LED array to generate the changing among different light colors by the pulse light modulation action of a single chip computer, combined light rays of a plurality of groups of different LED arrays can make varicolored gradually-light and gradually-dark scene generated in corresponding positions on the picture. The utility model has the advantages of lightness, thinness and energy saving; the utility model not only can be used as a decoration and lighting fixture on a wall in a living room, but also can be applied to the decoration for outdoor advertisements.

Description

A kind of energy-saving lamp box of photochromic conversion is drawn

Technical field

The utility model relates to a kind of lamp box picture device, and the lamp box that especially can produce the light innervation is drawn.

Background technology

At present, all known lamp boxes are decorated with the lamp box that constant photochromic static state draws and rely on motor to rotate to drive grating or colour table to rotate dynamic effects such as producing hydrodynamic(al) Yun Fei or variable color and draw on the market.Because of the needs motor rotates, wearing and tearing are big, and easily heating is fragile, and noise is arranged, and used light source is common fluorescent tube or incandescent lamp bulb, and volume is big, and heat generating components is arranged, and uneven illumination is even, and lamp box not only consumes energy very big, and casing is thick and heavy, poor safety performance; And for example, application number is 02207816.9 the dynamic picture device of micro computer, make light source although adopted the LED light emitting diode, but its structure is LED to be embedded in the poly (methyl methacrylate) plate be close to picture and perforate, intersperse picture by the luminous point that light hole produces on the picture, LED can not illuminate each part of whole image, does not have best picture light and becomes effect, and be easy to generate dazzling light when LED reaches high-high brightness, LED brightness does not have effective illuminance in the time of little.

Summary of the invention

Present lamp box is drawn product or technology has electrical components in order to solve, the thermal value that adopts common fluorescent tube or incandescent lamp bulb to cause is big, noise is arranged, power consumption is big, the light source volume that takes up room is big, fragile, or the distribution of light inequality that adopts LED to cause by prior art as light source, can not reach effective illuminance, with the problems and the defectives such as limitation of the utilization picture decorative effect that above technology played, the utility model provides a kind of employing superbright degree light emitting diode (superbright degree LED) array to make light source, no motor component, can control picture light level and colourity automatically changes, photochromic being evenly distributed, illuminance is big, can be used as indoor main light source or secondary light source and indoor and outdoor and decorates and to use with handicraft picture or public advertising, construct frivolously, extremely the Apyrexic energy-saving lamp box of low consumption is drawn.

This device is achieved in that on a width of cloth Lamp case frame, load onto picture, the circuit board that is welded with superbright degree led array is separately fixed in the Lamp case frame, and make superbright degree LED lamp holder keep Ullage towards picture and with picture, superbright degree LED is connected by electrical wiring on the control panel that is made of single-chip microcomputer and led drive circuit, control panel is connecting the stabilized voltage supply adapter, adds the back shroud sealing again and has constituted a lamp box picture of the present utility model.After powering on, this device is under the control of single-chip microcomputer, the pulse voltage control led drive circuit of output distinct pulse widths produces the pulse light modulation effect, make superbright degree led array produce different light level and photochromism, the light that superbright degree LED is given out shines on the picture by the Ullage between LED lamp holder and the picture; The superbright degree LED of control different parts or different colours makes the picture corresponding site produce different photochromic variations.

Owing to adopted superbright degree led array, LED lamp holder and picture leave Ullage, and automatic control and pulse light modulation that single-chip microcomputer is arranged, motor component and ordinary light source have been removed from, lamp box not only being consumed energy hang down does not have the heating noiseless, and the illumination uniform luminance is big, and photochromism is regulated freely, stable performance, safe and reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the exploded view of present embodiment complete machine structure.

Fig. 2 is the structural map of superbright degree led array circuit board (4) part among Fig. 1.

Fig. 3 is the control circuit schematic diagram of present embodiment.

Embodiment

By shown in Figure 1, square lamp box outside framework (1) is similar with existing Lamp case frame, the lamp box picture (2) of a PET material is sticked on the lamp box outside framework prosopyle (11), be pressed in above the picture (2) with inner frame (3), prosopyle (11) and inner edge (14) with the lamp box outside framework are fixed picture (2), two frameworks are bonded into a general frame simultaneously, then respectively three superbright degree led array circuit boards (4) are followed closely hole (42) and are fixed on the screw (31) of inner frame (3) by parallel the passing with screw (43) in upper, middle and lower position, the lamp holder of superbright degree LED is towards picture, because thereby inner frame has enough thickness to make LED lamp holder and picture remain with certain Ullage, lead (41) on three led array circuit boards (4) is connected on the control circuit board (5), and be fixed on the inboard of inner frame (3) together, line hole (32) and the line hole (13) on the outside framework (1) that power lead (51) is passed on the inner frame (3) are connected on external 5 volts of stabilized voltage supply adapters, be the complete machine power supply, at last base plate (6) with screw (62) pass nail hole (61) be fixed on outside framework (1) about about on the screw (12).The energy-saving lamp box that has constituted a photochromic conversion of present embodiment is like this drawn.

Fig. 2 has pointed out the positive surface construction of the superbright degree led array circuit board (4) shown in Fig. 1, it is by printed circuit board (45) and welding superincumbent superbright degree LED (44), lead (41) and nail hole (42) constitute, its front is a LED lamp holder face, the copper cash road surface is applied for printing in the back side, the lamp holder front is towards picture during installation, and the back side is towards base plate, as shown in Figure 1.

Fig. 3 is a control circuit schematic diagram that is made of for core AT89 single-chip microcomputer (51), and peripheral circuit is by oscillatory circuit (52), reset circuit (54), superbright degree led array driving circuit formations such as (53).Here used three single-chip microcomputer output ports and three corresponding driving circuit (53) to connect respectively in vain, indigo plant, the superbright degree led array of red three groups of different glow colors, wherein the LED of the every kind of same color employing and the mode that connects constitute a group pattern; Under the pulse control of single-chip microcomputer output, promote driving circuit (53) the generation pulse current that triode and resistance constitute, the electric current of different pulse widths makes superbright degree led array produce different brightness, the led array of three groups of different colours is combined into different photochromic and continuous variations, shines to make picture produce various photochromic conversion on the picture.
