Abstract
The invention provides an illumination device used for a lamp box, relating to the field of illumination electronic technique; the technical problems to be solved are that the existing illumination device of the lamp box can not control the dynamic change of the light color and has short service life, large electricity consumption and unsafe use; the illumination device of the lamp box comprises a light guide plate and a light source and is characterized in that the light source is an LED lamp strip which is arranged at the edge of the light guide plate; the light guide plate is divided into at least an area; each area is provided with at least an LED lamp strip; the illumination of the LED lamp strip is controlled by a controller; the controller comprises a stabilizer filter circuit, a singlechip control circuit and a power MOS tube; and the illumination device of the lamp box leads the lamp box to be colorful and moving, easily attracts the attention of passerby and has long service life, low energy dissipation and safe use.
Description
Technical field
The present invention relates to the electronic technology of throwing light on, particularly relate to a kind of technology of lighting device of LED lamp bar lamp box.
Background technology
Present lamp box all adopts fluorescent tube light source as a setting, and this lamp box can only staticly be showed picture, can not control its photochromic dynamic change, dull coloring does not have innervation, is not easy to cause passerby's attention, and fluorescent tube is short service life, power consumption is big, uses dangerous.
Summary of the invention
At the defective that exists in the above-mentioned prior art, the invention provides and a kind ofly can control photochromic dynamic change, and the lighting device of long service life, energy consumption lamp box low, safe in utilization.
In order to solve the problems of the technologies described above, the lighting device of a kind of lamp box provided by the present invention, comprise LGP and light source, it is characterized in that, described light source is a LED lamp bar of being located at the LGP edge, described LGP is divided at least one block, and each block is provided with at least one LED lamp bar, and LED lamp bar is controlled by a controller that it is luminous.
Further, described controller comprises filter circuit of pressure-stabilizing, single chip machine controlling circuit and power mos pipe.
Further, described LGP divides three blocks arranging in a triangle.
Further, described LGP is divided into three blocks of strip parallel arranged.
Utilize the lighting device of lamp box provided by the invention, owing to adopt the dynamic mapping between each block of LGP of Single-chip Controlling LED lamp bar photochromic, lamp box seems that rich color is rich dynamic, cause that easily passerby notes, increased demonstration effect, and owing to adopted LED as light source, long service life, energy consumption are low, safe in utilization.
