Description

LED lamp

Technical field

The utility model relates to lighting field, particularly a kind of LED lamp.

Background technology

In recent years, because the development of LED industry is rapid, LED lamp progressively replaces traditional lighting.Because LED luminescence has the characteristic such as spot light and directionality, therefore LED is difficult to replace conventional incandescent completely, accomplishes that full luminous intensity distribution throws light on.Existing a kind of LED light-emitting section, that one group of LED chip encapsulation is formed filament on the transparent substrate, then by multiple filament by being welded on illumination effect support bar being formed similar tengsten lamp, although although the light fixture of this structure is closely similar with traditional incandescent lamp, but owing to also will processing filament and be welded and fixed, there is the shortcoming that structure and assembly technology are complicated, production efficiency is lower.

Utility model content

In view of this, be necessary to provide a kind of structure simple LED lamp.

The technical solution adopted in the utility model is: a kind of LED lamp, include bulb housing, the pedestal be arranged in this bulb housing, be arranged at the substrate on this pedestal and be arranged at least one LED light source on substrate, also comprise at least one light-guiding pillar, the bottom of described light-guiding pillar is separately fixed at the top of this LED light source, the top of described light-guiding pillar is arranged towards the top of this bulb housing, the sidewall of described light-guiding pillar is interval with and multiplely gets photo structure, this gets photo structure for being reflected by the sidewall of the light in light-guiding pillar towards this bulb housing.

Compared with prior art, these LED light sources are directly arranged on this substrate by the utility model LED lamp, the light sent by these LED light sources by arranging these light-guiding pillars is only needed to be reflected on the sidewall of this bulb housing by the light guide structure of these light-guiding pillars, thus form the illumination effect of similar tengsten lamp, due to without the need to other encapsulated LED light source again, this LED lamp is made to have the simple advantage of structure.

Detailed description of the invention

Below by way of specific embodiment, the utility model is elaborated:

Fig. 1 is the profile of the utility model first embodiment LED lamp, and this LED lamp includes bulb housing 10, the pedestal 20 be arranged in this bulb housing 10, be arranged at the substrate 30 on this pedestal 20 and be arranged at least one LED light source 40 on this substrate 30.

Please refer to Fig. 1, this pedestal 20 is one-body molded by transparent or semitransparent Heat Conduction Material with this bulb housing 10.This pedestal 20 is clear glass rod structure, and this pedestal 20 is connected to form cavity with the bottom melting of this bulb housing 10.This pedestal 20 is connected to form airtight cavity with this bulb housing 10, is filled with high heat-conducting gas in this cavity, and the heat that this high heat-conducting gas is used for this LED light source 40 to produce is delivered to this bulb housing 10 by convection current.

Please refer to Fig. 1 to Fig. 3, this LED lamp comprises multiple LED light source 40, and these LED light sources 40 are arranged around the interval, middle part of this substrate 30, and this substrate 30 is positioned at the bottom of this bulb housing 10, and this substrate 30 is thermally coupled with the end face of this pedestal 20.The periphery of this substrate 30 is tiltedly installed with rake 32 relative to the middle part of this substrate 30, and described rake 32 is relative to tilting obliquely in the middle part of this or tilting obliquely, and these LED light sources 40 are arranged on the end face of this rake 32.

Please refer to Fig. 1, this LED lamp also comprises at least one light-guiding pillar 50, these light-guiding pillars 50 are strip structure, the bottom of these light-guiding pillars 50 is separately fixed at the top of these LED light sources 40, the bottom of these light-guiding pillars 50 is fixed by snap on this substrate 40, the top of this substrate 30 is provided with bracing frame 60, this bracing frame 60 comprises support column 61 and is arranged at the connecting plate 62 at this support column 61 top, the bottom of this support column 60 is fixed on this substrate 30, and the top of these light-guiding pillars 50 is individually fixed on this connecting plate 62.These light-guiding pillars 50 these rakes 32 substantially vertical are arranged, and the top of these light-guiding pillars 50 is arranged towards the top of this bulb housing 10.The sidewall of these light-guiding pillars 50 is interval with and multiplely gets photo structure 51, this gets photo structure 51 for being reflected by the sidewall of the light in light-guiding pillar 50 towards this bulb housing 10.In the present embodiment, these get photo structure 51 for being arranged on the fluorescent material mixed layer 511 of the side of these light-guiding pillars 50, this fluorescent material mixed layer 511 is site or the strip structure of printing formation, this fluorescent material mixed layer 511 converts white light to for the light sent by these LED light sources 40, and on the direction away from this LED light source 40, the photo structure 51 of getting of these light-guiding pillar 50 sides distributes more and more closeer.The end face of these light-guiding pillars 50 is also provided with this fluorescent material mixed layer 511.Preferably, the refractive index of these light-guiding pillars 50 is 1.52, this fluorescent material mixed layer 511 is mixed by fluorescent material and silica gel, and the refractive index of this fluorescent material mixed layer 511 is 1.48, and these light-guiding pillars 50 can need according to luminous intensity distribution with the refractive index of this silica gel and select.Refractive index due to fluorescent material mixed layer 511 is less than the refractive index of this light-guiding pillar 50, and light can be taken out by refraction from light-guiding pillar 50.In addition, this gets photo structure 511 also can for being arranged on the concave point on this light-guiding pillar 50, and on the direction away from this LED light source 40, the photo structure 511 of getting of these light-guiding pillar 50 sides distributes more and more closeer.Distribute more and more closelyer can take out more light from the top of light-guiding pillar 50, simultaneously, due to more near this LED light source 40 place distribution of light on this light-guiding pillar 50, the light finally sent from light-guiding pillar 50 so just can be made to trend towards uniformity, and make final lighting effect become even.

In sum, these LED light sources 40 are directly arranged on this substrate 30 by this LED lamp of the utility model, the light sent by these LED light sources 40 by arranging these light-guiding pillars 50 is only needed to be reflected on the sidewall of this bulb housing 10 by the light guide structure of these light-guiding pillars 50, thus form the illumination effect of similar tengsten lamp, due to without the need to other encapsulated LED light source again, this LED lamp is made to have the simple advantage of structure.In addition, the utility model by being provided with rake 32 on this substrate 30, these light-guiding pillars 50 these rakes 32 substantially vertical are arranged, like this, the light that these LED light sources 40 are sent is better by the guiding of this light-guiding pillar, more irradiate towards the top of this bulb housing 10, to obtain more uniform illumination effect.

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 made, equivalent replacements, improvement etc., all should be included within scope that the utility model protects.
