A kind of warm white label being conveniently replaceable
Technical field
The invention belongs to label fields, in particular to a kind of warm white label being conveniently replaceable.
Background technique
Label has the function of label, warning, can be used for the various places such as supermarket, lavatory, house, common sign board is big
Cause is divided into following several types: not luminous license plate, self illuminous sign board, reflecting at night sign board and using LED or lamp box as light
The active luminous sign board in source.But luminous license plate night is not difficult to observe, and the self illuminous sign board weak and fluorescent lifetime that shines is short,
Reflecting sign board night hyperopia result is poor, and uses Eu by the material of the active luminous sign of light source of LED2+The nitridation of doping
Object has high-quantum efficiency and comparatively ideal thermostabilization in red area since they have strong absorption in blue region
Property, therefore can be used to improve the performance of white light LEDs, become commercial LED red light material leading at present.However, nitride is wide
Excitation band it is Chong Die in the transmitting band of green area with YAG:Ce, generate self-absorption, therefore whole luminous efficiency can be made to drop
It is low.In addition, the synthesis condition of this nitride is harsher, starting material price is also more expensive, so that synthesis cost is high, and
Most of LED active luminous signs all use white light, more dazzling instead at night, influence observing effect.
And existing label generally uses being fixed in door body or wall for screw etc, it is this kind of to wall and door etc.
Structure will cause breaking-up, and when needing replacing label when old LED label is damaged, it needs overall pulling down influencing beauty
It sees, and dismounting is cumbersome, and the usage amount of label is larger, such as doorplate in the prior art, is all a monolith, text is to be engraved in
Above doorplate, special tool and craftsman is needed to engrave text, thus each piece of doorplate is all special, different text
Need to customize different doorplates, so, it is low, time-consuming and laborious that the LED label of the prior art there is poor universality, manufacture efficiency
Disadvantage, and there are no good antifouling capacities for label.For this purpose, it is proposed that a kind of lower-cost warm white being conveniently replaceable
Label, to solve the problems, such as to mention in above-mentioned background technique.
Summary of the invention
In conclusion in order to overcome the deficiencies of the prior art, the present invention provides a kind of warm white label being conveniently replaceable.
To achieve the above object, the present invention provides the following technical scheme that a kind of warm white label being conveniently replaceable, including
Label ontology and fixed plate, the fixed plate are set to label ontology back, described fixed plate one end and the label sheet
Body is hinged, and displaying chamber is provided in the label ontology, and the displaying is intracavitary to be provided with more than one display card, the mark
Board ontology corresponds to the LED light that the side for showing chamber is provided with diverging warm white, and the LED light is red using 12 fluogermanates
Luminescent material, the display card hollow out setting, the LED light are set to the display card back, and the light of the LED light passes through institute
The hollow out position of display card is stated, the other side of the relatively described fixed plate of label ontology is provided with card slot, sets in the card slot
It is equipped with transparent shutter compatible with the card slot, label ontology one end is provided with opening, the opening and the exhibition
Show that chamber, the card slot are connected, the opening is provided with dust guard.
By using above-mentioned technical proposal, fixed plate is fixed in material installed (door body or wall etc.), and display card is inserted
Set on the intrinsic displaying chamber of label, display card is arranged according to content in hollow out, and LED light is set to the display card back, LED
The light of lamp passes through the hollow out position of display card, and chiaroscuro forms display content, and LED light uses 12 fluogermanate feux rouges materials
Material, cost is relatively low, and LED lamplight is warm white, meets the illumination of high colour rendering index (> 85) and low color temperature (3000-4500K)
Demand can show that content is replaced to it, and there are more than one for display card as needed, by taking doorplate as an example, show content
, can be as needed including street name and number, two pieces of display cards for identifying street name and number respectively will be placed, it is identical
Street name and it is identically numbered repeatable manufacture or holding multiple pieces display card, each display card shows single text or volume
Number, display card content composition uses, and all customizes without each piece of doorplate, easily manufactured, easy, manufacturing cost is low, replacement cost
It is low, while replacing display content, without dismantling fixed plate, label ontology only need to be stirred, removes dust guard, by display card from opening
Place removes, i.e., replaceable, and transparent shutter is arranged for blocking display card.
The present invention is further arranged: being provided with holding tank, the holding tank and institute between the card slot and the displaying chamber
Opening in communication is stated, the amplification layout piece for amplifying the display card, the amplification layout piece are provided in the holding tank
