Description
Technical field
The utility model relates to a kind of light-guiding pillar, refers in particular to a kind of bulb lamp light-guiding pillar.
Background technology
Along with the high speed development of LED technology, LED illumination becomes the only choosing of novel green illumination gradually.LED is far superior to traditional lighting product in the aspect of principle of luminosity, energy-saving and environmental protection.At present, LED bulb lamp, as the one of novel green illumination, has extraordinary energy-saving effect, the in the situation that of equal light efficiency, and 1/2 of 1/8 and electronic energy-saving lamp of the incandescent lamp that energy consumption has dropped to.The bulb profile of LED bulb lamp is spherical, and what internal light source was selected is LED lamp pearl, possesses energy-conserving and environment-protective, service life long and without advantages such as stroboscopics.
In prior art, most LED bulb lamp light-guiding pillar is because global design scheme is unreasonable, distribution of light sources in LED bulb lamp is inhomogeneous, cause the central light strength in light fixture too strong, Integral luminous scope is less, light intensity a little less than, the illuminating effect that has affected LED bulb lamp, has also caused inconvenience to user.
In view of this, the inventor's specialized designs bulb lamp light-guiding pillar, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of bulb lamp light-guiding pillar, makes light-guiding pillar luminous evenly, improves illuminating effect.
To achieve these goals, the technical solution of the utility model is as follows:
Bulb lamp light-guiding pillar, comprise end face, cylinder and bottom surface, it is made that end face, cylinder and bottom surface are thermoplastic, and end face is provided with post piece, the side of post piece is made up of left and right two symmetrical curves, and curve is divided into the first arc, the second arc and the 3rd arc; The radius of the first arc is 2-3mm, and its angle is 15-20 °; The radius of the second arc is 3-5mm, and its angle is 25-30 °; The radius of the 3rd arc is 6-9mm, and its angle is 35-50 °; The lower end of end face connects cylinder, and bottom surface is fixed on the lower end of cylinder, and bottom surface is provided with column cavity, is equipped with LED chip in cavity.
Described thermoplastic is polycarbonate.
The diameter of described end face is greater than the diameter of cylinder.
To description of the present utility model, compared to the prior art, the utlity model has following advantage from above-mentioned:
The part that the utility model not only uses is less, simple in structure, and can realize within the scope of 300 ° luminous, and almost do not have light to penetrate outward 300 ° of scopes, solve the problem of most of traditional light-guiding pillar because of the not enough non-uniform light causing of distribution of light sources inequality or angle, be applied in bulb lamp and can improve the illuminating effect of bulb lamp.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Bulb lamp light-guiding pillar as shown in Figure 1, comprise end face 1, cylinder 2 and bottom surface 3, it is made that end face 1, cylinder 11 and bottom surface 3 are thermoplastic, and thermoplastic has that resistance to ag(e)ing, temperature limit are wide, environmental protection and refractive index advantages of higher, thereby strengthen the performance of light-guiding pillar.The thermoplastic of this embodiment is polycarbonate.
End face 1 is provided with post piece 11, and the side of post piece 11 is made up of left and right two symmetrical curves, and curve is divided into the first arc 12, the second arc 13 and the 3rd arc 14; The radius of the first arc 12 is 2-3mm, and its angle is 15-20 °; The radius of the second arc 13 is 3-5mm, and its angle is 25-30 °; The radius of the 3rd arc 14 is 6-9mm, and its angle is 35-50 °; The lower end of end face 1 connects cylinder 2, and the diameter of the end face 1 of this embodiment is greater than the diameter of cylinder 2, and bottom surface 3 is fixed on the lower end of cylinder 2, and bottom surface 3 is provided with column cavity 31, in cavity 31, is equipped with LED chip.
The utility model in use, LED chip in cavity 31 emits beam, if the light of launching and Y-axis angle are hour, light incides on the inner surface of post piece 2, reflect through polycarbonate material, then directly penetrate from post piece 2, make the light of ejaculation and the scope of Y-axis formation angle be-30 ° to 30 °; If when the light of launching and Y-axis angle are medium, light is incident on the inner surface of post piece 2, through the refraction of polycarbonate material, be then refracted to end face 1 top and penetrate thus, make the light of ejaculation and the scope of Y-axis formation angle be-30 ° to-100 ° and 30 ° to 100 °; If when the light of launching and Y-axis angle are larger, light is incident on the inner surface of post piece 2, through the refraction of polycarbonate material, be then refracted to end face 1 bottom and penetrate thus, make the light of ejaculation and the scope of Y-axis formation angle be-100 ° to-150 ° and 100 ° to 150 °.Generally speaking, the light of ejaculation forms 300 ° of scopes.
The part that the utility model not only uses is less, simple in structure, and can realize within the scope of 300 ° luminous, and almost do not have light to penetrate outward 300 ° of scopes, solve most of traditional light-guiding pillar because of distribution of light sources inequality or the problem of the not enough non-uniform light causing of angle, in the time being applied in bulb lamp, can improve the illuminating effect of bulb lamp.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
