Background technology
The candlelight of candle though can produce dim light, is made romantic atmosphere, can produce cigarette during burning candle, and neither environmental protection, and adventurous again misgivings can not expect that the interlude accident that troubles the air takes place and always have.
In order to improve aforesaid drawbacks, be flooded with the tinkling of jades electronic type candle-light lamp that meets the eye on every side on the market at present, announce No. 247774 case, No. 354699 case etc. as Taiwan, mainly be to be a lampwick cover emulation candlelight of candlelight profile.Yet, because being lampwick cover by entity, candlelight produced, therefore, can't there be candlelight to flash blurred visual effect, and gives a kind of stiff factitious sensation of people unavoidably.
Other consults Fig. 1, is example with a kind of electronic type candle-light lamp 1, and mainly comprising mounting has a lamp socket 11 of light source (figure do not show), this light source and be a lampwick cover 12 of candlelight profile relatively, and loads this lamp socket 11 and around a Lamp cup 13 of this lampwick cover 12.Whereby, make light-ray condensing in this Lamp cup 13, and produce blurred visual effect.
Yet, because this Lamp cup 13 is not exclusively transparent, therefore, the penetrance of light is low, have the shortcoming of luminance shortage, though and accumulate in light in this Lamp cup 13, blurred visual effect can be produced, but still need to rely on the lampwick cover 12 emulation candlelights that are the candlelight profile, and can give a kind of stiff factitious sensation of people equally.
Summary of the invention
The object of the present invention is to provide a kind of can the emulation candlelight and promote the lighting device of the generation virtual light source of the sense of reality.
The lighting device of generation virtual light source of the present invention comprises a light-emitting component, a lamp socket, and an optical element.This lamp socket is used for this light-emitting component of mounting.This optical element covers this light-emitting component, and has a summit that is positioned at this light-emitting component top, and by following a circular arc parabola to extend and around a conical walls of this light-emitting component in this summit, this conical walls is used for refracted ray, can produce a virtual light source that is positioned between this lamp socket and this summit.
The lighting device of generation virtual light source of the present invention, this light-emitting component are a light emitting diode.
The lighting device of generation virtual light source of the present invention, this optical element also have and are in reverse to this summit and an ora terminalis fixed with this lamp socket.
The lighting device of generation virtual light source of the present invention, this conical walls is the center with an axis by this summit, and this virtual light source extends along this axis.
The lighting device of generation virtual light source of the present invention, this optical element also have a space that is defined between this conical walls and this lamp socket, and this virtual light source is formed in this space.
The lighting device of generation virtual light source of the present invention also includes a lamp guide, and this lamp guide vertically-arranged and is used for directing light on this lamp socket.
The lighting device of generation virtual light source of the present invention, this virtual light source is formed in this conical walls.
The lighting device of generation virtual light source of the present invention, this optical element are a kind of lens.
Beneficial effect of the present invention is: can produce virtual light source with this optical element, and the sense of reality when promoting the emulation candlelight, and under the situation that does not influence brightness of illumination, make romantic atmosphere.

The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
Consult Fig. 2, Fig. 3, one first preferred embodiment that the present invention produces the lighting device of virtual light source comprises a light emitting module 2, a lamp socket 3, and an optical element 4.
This light emitting module 2 has a light-emitting component 21, a lamp guide 22 that reaches relative this light-emitting component 21 and extend along an axis X direction.This light-emitting component 21 can be general light fixture or bulb, is a light emitting diode in this preferred embodiment.This lamp guide 22 is used for directing light.
This lamp socket 3 is used for mounting this light-emitting component 21 and this lamp guide 22.
This optical element 4 is lens in this preferred embodiment, and have and be positioned at these light-emitting component 21 tops and a summit 41 by this axis X, be the center and follow a circular arc parabola to extend to encircle a conical walls 42 covering this light emitting module 2, be defined in a space 43 of 3 of this conical walls 42 and this lamp sockets, and be in reverse to this summit 41 and an ora terminalis 44 fixed with this lamp socket 3 by this summit 41 with this axis X.
Consult Fig. 3, Fig. 4, when this light-emitting component 21 is luminous, light by this light-emitting component 21 to around disperse, and can follow this lamp guide 22 to advance, make this lamp guide 22 luminous, at this moment, be dissipated into the light of the conical walls 42 of this optical element 4, can reach the parabola radian of this conical walls 42 because of refraction effect, there is part light directly outwards to disperse part light and then returns to this space 43 and converge in this optical element 4, and produce a virtual light source 5 that is positioned at 41 on this lamp socket 3 and this summit.
Whereby, because this virtual light source 5 is not a kind of entity material, and cooperate the shape of this conical walls 42, can different visual experiences be arranged, therefore along with the variation of visual angle, can flash blurred visual effect by the emulation candlelight, under the situation that does not influence brightness of illumination, make romantic atmosphere.
Consulting Fig. 5, is the present invention's one second preferred embodiment, and itself and this first preferred embodiment is roughly the same, and difference is in lamp guide 22 that this light emitting module 2 omits as shown in Figure 3, and directly covers this light-emitting component 21 with these optical element 4 rings.Whereby, can make part light then return to this space 43 with the refraction effect of this conical walls 42 equally, and produce the virtual light source 5 be positioned at 41 on this lamp socket 3 and this summit.
Consulting Fig. 6, is the present invention 1 the 3rd preferred embodiment, and itself and this second preferred embodiment is roughly the same, difference be in: this optical element 4 can change the thickness of this conical walls 42, virtual light source 5 is formed in this conical walls 42, whereby, produces different visual effects.
According to the above as can be known, the present invention's lighting device of producing virtual light source has following advantage and effect:
The present invention produces virtual light source 5, because virtual light source 5 is not a kind of entity material by the special design of this optical element 4, and can different visual experiences be arranged, therefore along with the variation of visual angle, can flash blurred visual effect by the emulation candlelight, significantly promote the sense of reality.And this optical element 4 can have different light transmittances, and can make romantic atmosphere under the situation that does not influence brightness of illumination according to the use needs.
