Description
Technical field
The invention relates to the display lamp that circuit demonstration etc. is located on advertisement sign, road name sign, the vehicles, be meant a kind of energy-saving ultra-thin LED plane display lamp especially.
Background technology
LED (Lighting Emitting Diode) has life-span length, power and energy saving, advantages such as response speed is fast, reliability is high, Environmental Safety.Along with the progress of science and technology, the luminous efficiency of LED is greatly improved, white LED light source be expected to become after incandescent lamp, fluorescent lamp and high-intensity gas discharge lamp the 4th generation light source.Recently, LED numerous areas in demonstration, illumination, automobile lamp, night scene engineering etc. has obtained very fast development.
The semiconducting compound chip light emitting belongs to the p-n junction electroluminescent, and the chip excitated fluorescent powder is realized transform light energy, belongs to luminescence generated by light.The most typical application scheme of this principle is the semiconductor chip of blue light-emitting and can be sent white light by the combination of the fluorescent material of blue-light excited jaundice light.According to complementary colors and complementary color equilibrium principle, as under forward voltage and forward current driving, the blue light part that the blue light-emitting led chip sends is absorbed by fluorescent material, and effectively excitated fluorescent powder sends gold-tinted, in the space of transparent material encapsulation, gold-tinted and blue light obtain white light.
At present, the lamp box type of fluorescent tube at aspect such as China's advertisement demonstration, public transport line or in adopting, the thickness space that needs is big, the life-span is short, safeguard difficulty, and what have is not attractive in appearance yet; Reflective sign only just has reverse reflective when light shines; Energy-accumulating luminous sign only just can embody effect when unexpected dark.
Summary of the invention
The object of the present invention is to provide a kind of energy-saving ultra-thin LED plane display lamp, what see when it disconnects lamp power is the original color of character and background thereof, as yellow green character white background, background becomes blueness and character becomes white when connecting power supply, to realize the different Show Color of day and night, more eye-catching, attractive in appearance, and specifically long-pending little, effect of saving energy.
For achieving the above object, solution of the present invention is: a kind of energy-saving ultra-thin LED plane display lamp, and it comprises display unit, the fixedly fixed frame and the power supply driver of display unit; This display unit comprises that a protective clear layer, a diffusion film layer, a LGP, are located at the LGP front and presents reflecting layer and several LED illuminating module that the fluorescent colloid layer, that needs displaying contents is fitted in the LGP back side; The LED illuminating module relatively is installed in the both sides of LGP in twos; And power supply driver is electrically connected with display unit.
Described protective clear layer is made for the organic or inorganic transparent glass material.
Described leaded light site is printed on the back side of LGP.
Described fixed frame is an aluminum alloy frame, is filled with heat-conducting cream between the inner groovy of LED illuminating module and aluminum alloy frame.
Described power supply driver is the control circuit of driving LED chip, is installed in the back side of fixed frame or places by electrical cables separate.
Led chip in the described LED illuminating module can be one or more mixing in blue light-emitting, ruddiness, green glow or other visible lights.
Led chip adopts DIP, SMT or COB mode to be welded on the PCB substrate of copper or aluminium in described each LED module, and per two LED illuminating module relatively are installed in the both sides of LGP, make LED side backlight.
Described fluorescent material is one or more mixing in yellow, green, red, blue or other visible color, and fluorescent material can effectively be excited by selected led chip.
Described this fluorescent glue is made into the thin layer oven dry and makes the upper surface that required character is attached to LGP.
The upper surface of described LGP is engraved as the character groove that needs, and fluorescent glue is to be filled in the groove of engraving, then oven dry.
After adopting such scheme, energy-saving ultra-thin LED plane display lamp of the present utility model is large-area luminous uniform surface light source, compare with the conventional fluorescent lamp box, and thinner thickness, it is little to take up room; By selecting different luminescence chips for use and can being realized different colours by this chip excited fluorescent powder collocation, the consumption difference of fluorescent material can realize the colour temperature difference; Under the natural light irradiation, character or symbol are the colors of observing of fluorescent material by day, under the night power-on, background is the color that led chip sends, character is the secondary colour of the light that sends of chip and fluorescent material, makes that to need the information that shows more eye-catching, also better appearance.
Therefore, the present invention has following advantage:
1, is made into background demonstration sign or the advertisement different as required with character color;
2, the color difference that looks of day and night, character and background color contrast are big, eye-catching;
3, planar light source, brightness is even, and is luminous soft, euphorosia;
4, thin thickness can directly be embedded on ceiling, body of wall or the ground, and it is little to take up room;
5, installation and maintenance are easy, and are with low cost, and integral body is not fragile;
6, non-environmental-pollution, nothing ultraviolet ray are polluted;
7, LED lamp source service life is long, energy-efficient, and is more energy-conservation more than 60% than conventional lightbank.
