Description

LED lamp board

Technical field

The utility model relates to a kind of LED lamp board by controlled in wireless, but this lamp board front is the LDE display screen of display text and animation, and the back side is the camber lamp box of replaceable lamp sheet.

Background technology

Existing LED lamp board kind has a lot, and it is not beautify the back side that these lamp boards have a common feature, can only place by wall by single face mostly, and LED lamp board is being needed in the two-sided place attractive in appearance, and these lamp boards can not satisfy people's demand far away.

In order to solve the problem that exists in the above technology, the utility model has been made following technical solution.

Summary of the invention

1, the utility model discloses a kind of LED lamp boards that to have tow sides Presentation Function, visibility be 160 degree, can carry out light modulation according to the bright intensity of surrounding environment, comprise left end cap, upper side frame, backlight, PCB wiring board, display screen, transparent panel, lower frame, right end cap, connection strap composition, as figure (1), right end cap comprises upper right lid, retainer plate, loudspeaker, CPU, right below cover; Left end cap comprises upper left lid, loudspeaker, pcb board, left below cover, as Fig. 3, at the front end of left and right sides end cap, the connector of two buckles is respectively arranged, on the PCB wiring board, several fixed strips are arranged, respectively there is a connector at the two ends of fixed strip, are the arc backlight in the back of PCB wiring board, in the front of PCB wiring board LED display are arranged, there is curved transparent front at display screen, in left end cap, loudspeaker are housed, left side control circuit plate is in right end cap, right control circuit plate is housed, master control IC, light sensing component and power amplifier, the utility model not only can be made electronic label, Advertisement label, but also can effectively play in conjunction with sound, each Xingqi duty of display screen and shady face, do not disturb mutually, visibility reaches 160 degree, can adjust the brightness of light by light sensing component automatically, to reach energy-conservation effect, light deformation type and kind have been enriched.The new feature of this practicality also is the mode of the connection employing clasp joint of left and right sides end cap, upper and lower side frame and pcb board, utilize self elasticity of plastic material to lock each web member, the front and back display surface is curved surface, visual range and aesthetic feeling have been strengthened, light sensing component and signal receiving module are installed in right end cap, light sensing component can be carried out light modulation automatically according to the strong and weak degree of the light of peripheral environment, signal receiving module can receive the instruction from mobile phone, by the processing of master control IC, carry out the replacing of displaying contents.Maximum characteristics of the present utility model are modes that clasp joint is adopted in the connection of left and right sides end cap, upper and lower side frame and PCB wiring board, utilize self elasticity of plastic material to lock each web member, the front and back display surface is curved surface, so visibility reaches 160 degree, light sensing component and signal receiving module are arranged in right end cap, the front has display screen to show, the back can show lantern slide under the irradiation of interior light.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a disintegration structural drawing of the present utility model.

Fig. 2 is combined effect figure of the present utility model.

Fig. 3 is a longitudinal sectional drawing of the present utility model.

Fig. 4 is the utility model left and right sides end cap assembling assumption diagram.

Embodiment:

But the utility model discloses a kind of front display text and animation, the LED lamp board of magic lantern can be play in the back side, mainly comprise right end cap 1, loudspeaker 3, CPU4, left end cap 6, upper and lower side frame 7, transparent panel 8, LED display 9, PCB wiring board 10, connection strap 11, backlight 13, backlight control plate 15, LED display is welded on the PCB wiring board, carry out hook lock as figure (4) by fixed strip 11 and frame, it is closely linked to each other, preceding transparent panel and back backlight push from the upper and lower side frame side respectively, the connector of left and right sides end cap inserts in the link slot of upper and lower side frame, carry out hook lock, make its one-tenth as a whole, whole LED lamp board can be connected and fixed by fixed screw piece 12 and external accessory.CPU in the right end cap is controlling the signal that LED dot matrix light transformation situation and light sensing component are transmitted, and result is fed back to light modulator, has reached the purpose of light modulation.Signal receiving module is handled through master control IC after receiving extraneous instruction, feeds back to actuator and carries out, to reach the purpose of changing displaying contents by mobile phone.

Claims

1. LED lamp board, mainly comprise left end cap, upper side frame, back backlight, PCB wiring board, display screen, preceding transparent panel, lower frame and right end cap, it is characterized in that: the mode of clasp joint is adopted in the connection of left and right sides end cap, upper and lower side frame and PCB wiring board, the front and back display surface is curved surface, visibility reaches 160 degree, and light sensing component and signal receiving module are arranged in right end cap.
