Description
Technical field
The utility model relates to semiconductor technology, refers to especially a kind of led lighting night-light device.
Background technology
Night-light is a kind of lighting device of built-in sensitization automatic switch, is used for lighting suitable luminosity at pitch-dark environment and conveniently walks about.Although family expenses are many, some relatively more black commercial environment such as bar, dining room and cinemas also use night-light.Have different requirements based on different environment, so for example the corridor is long and narrow will rectificate and narrow light belt, cubicle such as bedroom requires light belt, big room such as parlor soft and that the plane is wide to require light relatively and wide light belt stair and family movie institute then require earthward wide light belt comprehensively.The leaded light band design that this shows night-light is very important.
The structure of the widely used direct insertion mini light night of people generally includes a light fixture box body, be provided with an illuminator in the box body, offer a transparency window at the sensitive surface of box body, shady face at box body then is provided with a plug that is connected with the illuminator drive circuit, plug directly inserts on wall socket or other power panel with jack and switches on, the incandescent lamp that its illuminator generally adopts the general lighting of 1.5W ~ 10W to use, the light that the mini light night of this structure is launched is directly concentrated to external exposure by transparent window, the non-uniform beam that sends produces dazzling sensation easily when nighttime sleep, the impact sleep, and, because the inner incandescent lamp of installing can generate heat, when using, children can scald one's hand, and dangerous, in addition, the incandescent lamp power consumption is large, service life is short, generally at 1000 hours ~ 1500 hours, needs often to change.Therefore, more and more people like replacing incandescent lamp with light emitting diode (LED, Light Emitting Diode).
Light emitting diode (LED, Light Emitting Diode) is a kind of semiconductor diode, is formed and is had unilateral conduction by a PN junction, can become luminous energy to electric energy conversion; After adding forward voltage to light emitting diode, be injected into the hole in N district from the P district and be injected into the electronics in P district by the N district, near PN junction in several microns respectively with the electronics in N district and the hole-recombination in P district, produce the fluorescence of spontaneous radiation.Electronics is different with the residing energy state in hole in the different semiconductors, and what are different for the energy that electronics discharges during with hole-recombination, and the light wavelength that the energy that discharges sends more at most is shorter.What usually use is the diode that can send ruddiness, green glow or blue light.And white light LEDs, generally the light emitting diode by blue chip adds that yellow phosphor powder mixes.LED than service life of incandescent lamp longer and more power saving its universalness is increased.
Although LED is than incandescent lamp longevity and power saving, owing to structural difference, the photism of LED is relatively more straight and therefore focusing have harder sensation, and too late incandescent lamp is soft and coverage is large.Therefore general LED night-light all can have the diffuser of non-all-transparent to be used for preventing that high light is directly according to eyes of user and raising coverage.Usually can add again that opaque outer cover such as metal picks up gear and do not want the scope that covers.The also light shield of useful arc is because can produce different light belts in the different curves.So the night-light of these different purposes has different outward appearances not outer humorous, build is thicker not attractive in appearance, more increases the chance of being run into, especially in narrow hallways.Present night-light on the market can not reach the purpose of outward appearance harmony and province's position safety etc. simultaneously.
The utility model content
The technical problems to be solved in the utility model provides a kind of direct insertion, and is not dazzling, the multi-angle light belt, and multispectral led lighting night-light device is used for solving the existing safety problem that the night-light outward appearance can not be unified and thickness causes more greatly.
For solving the problems of the technologies described above, the utility model provides a kind of led lighting night-light device, it comprises: the lid that has loophole in the middle of the plastic seat body and, be provided with at least one LED illuminant heart in the described plastic seat body, the drive circuit of described illuminator is electrically connected with the input of the plug that is positioned at described plastic seat body, this drive circuit has the switching circuit from sensitization, and the outer surface of the protruding described plastic seat body of input of plug is to be electrically connected with supply hub; Be provided with a guiding device in plastic seat body and lid interface, this guiding device comprises a transparent light guide plate, and the periphery of described transparent light guide plate is provided with at least one angle ditch, and each angle ditch can enclose around being linked to be an angle ditch in one week of transparent light guide plate.
By the setting of transparent light guide plate one or more groups, the angle ditch of equal angular or different angles encloses, described transparent light guide plate can be when keeping special thin build, can make again different coverages but uniform light belt.
The shady face of described transparent light guide plate can have one deck light-transmissive film or reflective membrane, and light-transmissive film or reflective membrane can be selected different colours and different transparencies as required.
Described illuminator is LED semiconductor cooling light modulation, LED in this LED semiconductor cooling light modulation can be same limit or the different edge that homochromy (such as blue light commonly used) is positioned at this night-light device, to strengthen luminosity, also can be a plurality of different color lights (such as blue light and gold-tinted), various tone simultaneously.
Led lighting night-light device of the present utility model encloses and reflective membrane owing to being provided with the angle ditch at the transparent light guide plate, the light that can effectively illuminator be sent is outwards derived, simultaneously, organize the angle ditch encloses and makes the distribution of light sent evenly and can make light soft not dazzling more; And when illuminator adopts LED semiconductor cooling light modulation, both can prolong the service life of mini light night (led lighting night-light device), again can be when children use non-scald on hand, its slim build also can reduce the chance that the user runs into, thereby reach attractive in appearance, practical, power saving, the effect of environmental protection and safety.
