Abstract
The utility model relates to a noctilucent key device which comprises a keycap, a key baseplate matched with the keycap, and a character inlaid in the keycap, wherein noctilucent material is coated on the character or the key baseplate. The noctilucent key device provided by the utility model is applicable to the field of equipment operated through keys, and is simple in principle and easy in popularization; and the adopted noctilucent material shines uniformly on the key and has strong luminous intensity, so that the adoption of an electric lighting device such as an LED and the like is avoided, and energy is saved.
Description
[technical field]
The utility model relates to electronic product, particularly a kind of noctilucent key-press device.
[background technology]
Along with the continuous development of electronic information science and technology, the use of electronic product more and more widely.Traditional electronic product key-press backlight lamp generally adopts light-emitting diode (LED) to realize.Generally be provided with one to several LED, yet, problems such as illumination deficiency or button brightness irregularities often arranged in the zone that LED is not set in certain location.
[utility model content]
Problems such as illumination deficiency that exists for the back lighting device that solves conventional keys or button brightness irregularities are necessary to provide a kind of high brightness, luminous uniform noctilucent key-press device.
A kind of noctilucent key-press device, the button base plate that comprise keycap, cooperates with keycap and be embedded in character in the keycap scribbles Noctilucent material on described character or the button base plate.
Preferably, described Noctilucent material be with the strontium aluminate as the parent crystallization, mix the light-accumulating luminescent material that the rare earth metal element is made, described Noctilucent material is uniformly coated on described character or the button base plate.
Preferably, also be included as the press key lamp circuit arrangement that Noctilucent material provides extinction light source or illuminated keyboard.
Preferably, described keycap is that transparent material is made, and described character is that transparent materials is made.
Noctilucent key-press device of the present utility model applicable all need the apparatus field of button operation, and principle is simple, is convenient to promote, employed Noctilucent material is luminous even on button, and luminous intensity is big, avoids using electricity lighting devices such as LED, saves the energy.
[description of drawings]
Fig. 1 is an embodiment schematic diagram of the utility model noctilucent key-press device.
Fig. 2 is another embodiment schematic diagram of the utility model noctilucent key-press device.
[embodiment]
Below main accompanying drawings noctilucent key-press device of the present utility model.
Make button with Noctilucent material, make that the user can discern each button by noctilucence easily when using the button electronic product under the situation of night or illumination deficiency, and owing to Noctilucent material is evenly distributed, so key-press backlight is also just more even.
Be illustrated in figure 1 as an example structure figure of the utility model noctilucent key-press device.The noctilucent key-press device comprises keycap 110, the button base plate 120 that cooperates with keycap 110 and is embedded in character 130 in the keycap 110.Keycap 110 and button base plate 120 adopt common PBT (polybutylene terephthalate, polybutylene terephthalate (PBT)) plastic production, by on character 130, being coated with Noctilucent material, character 130 is embedded in the transparent keycap 110, can reflects the noctilucence that character 130 sends clearly.
Be illustrated in figure 2 as another example structure figure of noctilucent key-press device.By coating one deck Noctilucent material on button base plate 220, character 230 adopts opaque material to make, and the noctilucence that Noctilucent material sends sees through transparent keycap 210 can well foil character 230 on button base plate 220.
Preferably, Noctilucent material is efficient light accumulation type material, with the strontium aluminate as the parent crystallization, mix rare earth metals such as highly purified aluminium oxide and strontium carbonate, do not contain radioactive substance, can in a night, keep luminous, luminous intensity height simultaneously is 100 times of traditional Noctilucent material.
In preferred embodiment, the noctilucent key-press device also comprises the press key lamp circuit arrangement, to solve under the extreme case the fully problem of extinction of Noctilucent material.When Noctilucent material was can not be normal luminous, the user can be by the interface menu setting, and using the press key lamp circuit arrangement to be chosen as Noctilucent material provides the extinction light source or directly use the press key lamp illuminated keyboard.
Noctilucent key-press device of the present utility model applicable all need the apparatus field of button operation, and principle is simple, is convenient to promote.Employed Noctilucent material is luminous even on button, and luminous intensity is big, avoids using illuminations such as LED, saves the energy.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
