The specific embodiment
See also Fig. 1, be depicted as the structural representation of the crystal lamp of the utility model the first embodiment.Crystal lamp 1 of the present utility model comprises a substrate 11, one first LED source 12, one second LED source 13, one first optical element 14 and one second optical element 15.
Please consult simultaneously Fig. 1 and Fig. 2, Figure 2 shows that the generalized section of the crystal lamp 1 of the utility model the first embodiment.Wherein, substrate 11 can be a circuit board, and the first LED source 12 and the second LED source 13 are arranged on the substrate 11.The first optical element 14 comprises the top that one first light-guiding pillar 141 and a first lens 142, the first light-guiding pillars 141 are arranged at the first LED source 12, and first lens 142 is connected in the first light-guiding pillar 141.First lens 142 and the first light-guiding pillar 141 can be Unitary injection formed, to form the first optical element 14.
It should be noted that, " the first light-guiding pillar 141 is arranged at the top of the first LED source 12 " is not when meaning crystal lamp 1 use or running, the first light-guiding pillar 141 must be positioned at the top of the first LED source 12, but when meaning substrate 11 and being placed in a horizontal plane, the top that the first light-guiding pillar 141 is positioned at the first LED source 12 gets final product.
The second optical element 15 comprises the top that one second light-guiding pillar 151 and one second lens, 152, the second light-guiding pillars 151 are arranged at the second LED source 13, and with the first light-guiding pillar 141 side by side.The second lens 152 are connected in the second light-guiding pillar 151.The second lens 152 and the second light-guiding pillar 151 can be Unitary injection formed, to form the second optical element 15.
The second lens 152 can be a meniscus lens (meniscus lens), the similar dome of its external form or a shell case.The second lens 152 coat first lens 142, namely refer to the concave surface contact of the second lens 152, the convex surface of applying first lens 142.One interface 142a of first lens 142 and the second lens 152 can be coated with an aluminium oxide, and this aluminium oxide color is light-permeable.The first LED source 12 can penetrate via this first lens 142 and this second lens 152, via reflection and the refraction of different contact-making surfaces, makes crystal lamp 1 simulate the light efficiency similar to flame.
Better, the first LED source 12 can be a main light source, its photochromic mainly present for crystal lamp 1 photochromic, and the second LED source 13 is a secondary light source, secondary light source is in order to auxiliary main light source.When main light source and secondary light source and time spent, because the mixed light of light can make the light efficiency of generation comparatively various, soft.The light that the first LED source 12 and the second LED source 13 produce penetrates by the first optical element 14 and the second optical element 15 respectively, then comes together in the light efficiency center, produces the optical effect of similar candle wick.
See also Fig. 3, be depicted as the schematic appearance of the crystal lamp 1 of the utility model the first preferred embodiment.Crystal lamp 1 more can comprise a cover body 31 and a base 32, and cover body 31 has an accommodation space 311, and base 32 connects cover body 31, and is used for connecting an external power source 33.Cover body 31 has a globular part 312 and and lengthens tail end 313, lengthens tail end 313 and is arranged on the globular part 312; In other embodiment (not shown), cover body also can only comprise a globular part.The above-mentioned substrate of mentioning 11, the first LED source 12, the second LED source 13, the first optical element 14 and the second optical element 15 are contained in the accommodation space 311, and substrate 11 can be electrically connected with base 32, the electric energy that is provided to receive external power source 33.
The surface of one bottom of cover body 31 (namely globular part 312 near the surface of base 32) is the surface 314 of processing once atomizing.Because the bottom that is centered close to crystal lamp 1 of light efficiency, for between the light efficiency of avoiding each LED source to produce obvious color range being arranged, when light efficiency by the surface 314 after processing through atomizing, can be so that the boundary line of the light efficiency that main light source and secondary light source produce to be comparatively not obvious, the whole light efficiency that makes crystal lamp 1 is a soft warm colour light.What the material of cover body 31 was better is glass, and the material of base 32 is metal, and what metal was better is aluminium.
The first light-guiding pillar 141 of crystal lamp 1 and the second light-guiding pillar 151 can be the light-guiding pillar of a hollow tubular, or a solid light-guiding pillar; If during the light-guiding pillar of hollow tubular, its inner rim also can be coated with an aluminium oxide.The first optical element 14 and the second optical element 15 can be made by different materials, and can produce in the lump by extra quality ejaculation (or claiming the bag mould to penetrate).
In this embodiment, utilize the LED source collocation of two kinds of different colours, and adjust the degree of light modulation by an adjustable resistance, to reach the variation of brightness and color.And can utilize a counter, and reach clocking capability, change in time the brightness of LED source, with simulation candle situation Suddenly it apperared and disappered.The electronic components such as above-mentioned adjustable resistance and counter can be arranged on the substrate 11.
See also Fig. 4 and Fig. 5, Figure 4 shows that the structural representation of the crystal lamp 1 of the utility model the second embodiment, Figure 5 shows that the generalized section of the crystal lamp 1 of the utility model the second embodiment.Compared to the first embodiment of the present utility model, the crystal lamp 1 of the second embodiment more comprises one the 3rd LED source 51 and one the 3rd optical element 52.
The 3rd LED source 51 is arranged on the substrate 11, and the 3rd optical element 52 has one the 3rd light-guiding pillar 521 and one the 3rd lens 522.The 3rd lens 522 and the 3rd light-guiding pillar 521 can be Unitary injection formed, to form the 3rd optical element 52.The 3rd light-guiding pillar 521 is arranged at the top of the 3rd LED source 51, and with the second light-guiding pillar 151 side by side.The 3rd lens 522 are connected in the 3rd light-guiding pillar 521, and the 3rd lens 522 coat the second lens 152.
In this embodiment, utilize the LED source collocation of three kinds of different colours, the product design of crystal lamp 1 can be according to different clients' demand, adjust the number of LED source, and along with the number of LED source and optical element increases, color gradually the layer effect more obvious, the situation that this crystal lamp simulating flame is slowly burnt is more true to nature.
The first embodiment in the utility model and the second embodiment, in the time of more can utilizing the flame of the moving candle of this counter simulation wind, the situation that fray-out of flame is lighted again, and can in controller, add the program of finishing writing in advance, be fixed mode or stochastic model according to the above-mentioned situation of user's requirements set, reach candle flame and intend genuine effect.
The above embodiments only are used for exemplifying enforcement aspect of the present utility model, and explain technical characterictic of the present utility model, are not to limit protection category of the present utility model.Any be familiar with this operator can unlabored change or the arrangement of isotropism all belong to the scope that the utility model is advocated, rights protection scope of the present utility model should be as the criterion with claim.
