Abstract

The utility model relates to night lighting equipment, in particular to a multifunctional light guiding device which is designed for solving the technical problem that the existing LED lamp product, the light-emitting keyboard and the keyboard membrane have poor structures. An LED circuit of the light guiding device is arranged in a circuit shell and is provided with an outer power supply device and is refracted in a light guiding membrane by light so as to achieve the purpose of lighting. The key point is as follows: one side of the LED circuit is provided with a surface-mount type LED lamp which is arranged at the edge of one side of the light guiding membrane; the LED circuit, the surface-mount type LED lamp and the light guiding membrane are connected into a whole; the LED circuit is provided with a brightness adjusting button and a USB wire; and the LED circuit is internally provided with a storage battery. The multifunctional light guiding device has the advantages of less energy consumption, good light guidance and flexibility, convenient use, wide use range, simple manufacturing technique and low cost, and is applicable to night lighting for non-light-emitting planar objects such as the keyboard, electronic books, books and the like.

Description

The multi-functional light-conducting device

Technical field

The utility model relates to night illumination equipment, is a kind of multi-functional light-conducting device.

Background technology

Along with people's material life raising, present many electronic products and people's life is closely bound up, even on very close terms, as electronic products such as notebook computer, desktop computer, electronic book browsers; These electronic products continued to be used by people through the night of being everlasting simultaneously, needed to adopt lamp lightings such as desk lamp, fluorescent lamp.But along with people improve energy-conserving and environment-protective consciousness, lamp lighting causes energy resource consumption bigger, influences other people sleep and rest.Therefore, arise at the historic moment as products such as LED lamp, usb-LED rechargeable lamps, but these LED light fixture product structures are not good enough, the field of illumination is less, and is difficult to carrying out effective lighting than big plane, carries, uses comparatively inconvenience.

Simultaneously, all have keyboard in many electronic products, keyboard is as modal computer entry device, computer operation person imports various instructions, data by keyboard to computer, the work of command computer, and be widely used in microcomputer, and on the various terminal device.For making things convenient for keyboard to use at night, do not influence other people rest, patent No. ZL200820023640.4 as the Chinese patent literature publication, Granted publication CN201207347Y, March 11 2009 Granted publication day, utility model title " fluorescence keyboard membrane ", this fluorescence keyboard membrane comprises keyboard membrane cover and fluorescence word, described keyboard membrane cover is made by the softer plastics of a kind of quality; The fluorescence word is embedded in the keyboard membrane cover, arranged evenly according to computor-keyboard, and the fluorescence word is the key of correspondent button on the keyboard.But above-mentioned keyboard membrane and keyboard difficulty separate, and function is comparatively single.

Summary of the invention

For solving above-mentioned deficiency, the utility model purpose is the multi-functional light-conducting device that a kind of plane is provided to this area, make it solve that existing LED light fixture product structure not good enoughly causes carrying inconvenience, the field of illumination is little, and existing illuminated keyboard, the keyboard membrane scope of application are little, the technical problem of function singleness.Its objective is and be achieved through the following technical solutions.

A kind of multi-functional light-conducting device, this lightguide comprise led circuit, adopting surface mounted LED lamp, light guiding film, and led circuit is arranged in the circuit case, and led circuit is provided with the externally fed device, reflects in light guiding film by light, reaches illumination purposes.Its design main points are that described led circuit one side is provided with the adopting surface mounted LED lamp, and the adopting surface mounted LED lamp is arranged at a side edge of light guiding film, and led circuit, adopting surface mounted LED lamp, light guiding film are connected as a single entity; Led circuit is provided with brightness regulation button and usb wiring.Light guiding film adopts translucent refracted ray material to make, start the work of adopting surface mounted LED lamp by led circuit, the light of adopting surface mounted LED lamp is dispersed on the light guiding film by light guiding film, is used for the illumination of the illumination of various flat objects, particularly keyboard, electronic book browser, books.

Be provided with storage batteries in the described led circuit, the storage battery in the led circuit charged, use during for night illumination by usb wiring and external transformation charger.

For conveniently fixing this lightguide, and be orientated keyboard and use, described light guiding film is provided with the keyboard tongue and groove, the circuit case of led circuit is provided with geometrical clamp, keyboard tongue and groove and geometrical clamp have made things convenient for this lightguide fixing at keyboard, simultaneously the keyboard tongue and groove has made things convenient for the location of " F " and " J " key in the keyboard, and the pushing of other key.Simultaneously, geometrical clamp has made things convenient for this lightguide fixing on non-luminous flat type article.

The utility model energy consumption is little, and light conductivity, softness are good, easy to use, and the purposes scope is wide, and manufacture craft is simple, cost is low, is applicable to the night illumination of non-luminous flat type article such as keyboard, e-book, books.
