Abstract

The utility model discloses a light guide post-type lighting lamp. The lighting lamp is characterized by comprising a light guide post, at least one light emitting component and a cooler, wherein the light guide post has a top surface and a bottom surface which are opposite to each other and a side surface connected between the top surface and the bottom surface; the light guide post has an annular cross section, and a reflective film is arranged on the annular inner surface; the light emitting component is arranged on the bottom surface or the top surface; light emitted by the light emitting component enters the light guide post through the bottom surface or the top surface, and then is reflected by the reflective film to penetrate out of the side surface; and the cooler is connected with the light emitting component and is arranged outside the light guide post. The light guide post-type lighting lamp provided by the utility model has good heat dissipation performance, and can use a high-power LED light source to realize high luminous efficiency and attractive appearance.

Description

A kind of leaded light column type lightening lamp tool
Technical field
The utility model relates to a kind of brightening light fixture, relates in particular to a kind of leaded light column type lightening lamp tool.
Background technology
The traditional lighting light fixture all be take fluorescent lamp and incandescent lamp bulb as main.Because the luminous efficiency of light emitting diode (Light Emitting Diode, LED) constantly promotes, make light emitting diode be applied on lighting replacing gradually fluorescent lamp and incandescent lamp bulb.Light emitting diode and conventional bulb have absolute advantage in comparison,, life-span length, low-voltage/current drives little such as volume, be difficult for breaking, containing characteristics such as mercury (there is no pollution problem) and luminous efficiencies good (power saving).
It is the strong structure of post that the brightening light fixture has many as lighting a kind of, add a circular mask composition but establish the lamp source in mostly being, cause so inner without heat-dissipating space, so power is all little, add and want that surface uniform is luminous needs to use diffusion material, yet can cause like this light to appear seldom.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of good heat dissipation, can use the leaded light column type lightening lamp tool of high-power LED light source .
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of leaded light column type lightening lamp tool comprises:
One light-guiding pillar, have a relative end face and a bottom surface, and be connected in described end face and Jian side, described bottom surface, and the cross section of described light-guiding pillar is an annular, and the inner surface of described annular is provided with one deck reflectance coating;
At least one light-emitting component, be arranged at described bottom surface or described end face place, and the light that described light-emitting component sends enters described light-guiding pillar via described bottom surface or described end face, and pass described side via described reflectance coating reflection; And
Radiator, be connected with described light-emitting component, and be positioned at described light-guiding pillar outside.
Described light-emitting component is two, and is arranged at respectively described end face and described bottom surface.
Described light-emitting component comprises circuit substrate, and the front of described circuit substrate is provided with a plurality of LED, and the back side of described circuit substrate is connected with described radiator.
Compared with prior art, the beneficial effects of the utility model are:
1. because leaded light column type lightening lamp tool of the present utility model is arranged at light-emitting component at bottom surface or the end face place of light-guiding pillar, so just make light-emitting component there is larger heat-dissipating space, so just can use high-power LED light source, in order to meet the demand that brightness is large, therefore the utility model thermal diffusivity is better, can use high-power LED light source.
2. because leaded light column type lightening lamp tool of the present utility model is provided with one deck reflectance coating in the inside of light-guiding pillar, after the light that light-emitting component sends enters light-guiding pillar, therefore reflection by reflectance coating makes the light-guiding pillar entirely lighting, has a light efficiency better, and soft advantage attractive in appearance.
The accompanying drawing explanation
Describe the utility model in detail below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present utility model.
The view in transverse section that Fig. 2 is the described light-guiding pillar of Fig. 1.
In figure: light-guiding pillar 2, light-emitting component 4, radiator 6, end face 21,22, side, bottom surface 23, reflectance coating 24, circuit substrate 41, LED 42.
The specific embodiment
As shown in Figure 1, a kind of leaded light column type lightening lamp tool of the present utility model, comprise: light-guiding pillar 2, light-emitting component 4 and radiator 6, wherein light-guiding pillar 2, have a relative end face 21 and a bottom surface 22, and are connected in end face 21 and 22Jian side, bottom surface 23, and light-guiding pillar 2 is cylindrical structural, as described in Figure 2, the cross section of light-guiding pillar 2 is an annular, at the inner surface of annular, is provided with one deck reflectance coating 24, light-emitting component 4 is two, and be arranged at respectively end face 21 and 22 places, bottom surface, it comprises circuit substrate 41, the front of this circuit substrate 41 is provided with a plurality of LED 42, the back side of circuit substrate 41 is connected with radiator 6, make like this radiator 43 be positioned at the outside of light-guiding pillar 2, thereby make the utlity model has splendid thermal diffusivity, so just can use the LED light source that power is higher, in order to meet the demand of high brightness, the light that light-emitting component 4 sends enters light-guiding pillar 2 via bottom surface 22 and end face 21, and 23 penetrate from the side via reflectance coating 24 reflections, this mode can make light-guiding pillar 2 entirely lightings, there is light soft attractive in appearance, light efficiency is advantage preferably.
In actual the use, light-guiding pillar 2 adopts PMMA (acryl) material, and reflectance coating 24 is the nanometer reflection material.
The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of putting down in writing in claims.
