Description
Technical field
The present invention relates to a kind of LED lighting device, particularly a kind of all-round smooth LED lamp.
Background technology
In recent years, LED chip applies to room lighting field as light source and is developed fast.People a kind ofly can overcome the difficult problem that LED light distribution angle is little constantly exploring.Traditional G9-LED lamp, its light distribution angle degree is generally less than 180 degree, due to the solid luminescence characteristic of LED light source, makes it be difficult to accomplish that wide-angle is luminous.In order to increase lighting angle, people attempt light source to be arranged on multiaspect column.For example open day is on April 24th, 2013, the patent No. is that 201220120513.2 Chinese utility model patent has disclosed a kind of G9-LED bulb, include base, driven unit, shell, LED lamp plate, lampshade, it is characterized in that: described base has two pins that connect power supply, described shell is the connector of a cylinder and multiaspect axle, the mouth cylinder of shell and base socket, cylinder interior is mounted with driven unit, the multiaspect axle multiple directions of shell are settled SMD LED paster, described lampshade is that transparent plastic is made, all SMD LED pasters on multiaspect axle are covered, be nested with the bottom of cylinder of shell.
Although this method can increase the brightness of this LED lamp side, need to weld in each side a plurality of LED chips, this just makes this LED lamp wiring dazzling, and manufacturing process is complicated, is not easy to assembling and produces.
Summary of the invention
In view of this, be necessary to provide a kind of good visual effect, the all-round smooth LED lamp that simple in structure and lighting angle is large.
A kind of all-round smooth LED lamp, comprise lens, LED light source plate and body, the bottom cover of these lens is located at the top of this body, this LED light source plate comprises substrate and is arranged on a plurality of LED light sources on this substrate, this LED light source plate is arranged on this body top, it is characterized in that, the corresponding described LED light source in bottom of these lens is provided with caustic surface, the end face of these lens is provided with reflective surface, this caustic surface reflects towards this reflective surface for the light that described LED light source is sent, this reflective surface is used for most of light towards this lens sidewall reflects, light is through the outside of direct this all-round smooth LED lamp of directive after these lens.
Compared with prior art, this all-round smooth LED lamp is provided with caustic surface and is provided with reflective surface for luminous intensity distribution at the top of lens in the bottom of lens, during work, this caustic surface by light-ray condensing to this reflecting surface, this reflecting surface by light towards this lens sidewall bottom reflection.Owing to being provided with this lens, make this all-round smooth LED lamp not need to arrange a plurality of for the side of LED chip is installed, this just makes this all-round smooth LED light fixture have good visual effect, the advantage that simple in structure and lighting angle is large.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail.
Please refer to Fig. 1 to Fig. 3, this all-round smooth LED lamp 100, comprise lens 10, LED light source plate 20 and body 30, the bottom cover of these lens 10 is located at the top of this body 30, this LED light source plate 20 comprises substrate 21 and is arranged on a plurality of LED light sources 22 on this substrate 21, this LED light source plate 20 is arranged on this body 30 tops, and the corresponding described LED light source 22 in bottom of these lens 10 is provided with caustic surface 121, and the end face of these lens 10 is provided with reflective surface 11.
Please refer to Fig. 1 to Fig. 4, these lens 10 are column structure, the undersized of these lens 10 sidewalls in or be greater than the size of this body 30.Preferably, the size of these lens 10 sidewalls is more than 0.8 with the scope of the ratio of the size of this body 30, like this, can prevent that this body 30 from blocking the light sending from these lens 10 sidewalls.The bottom cover of these lens 10 is located at the top of this body 30.These lens 10 bottom margins are provided with pin 13, and this pin 13 is connected and fixed by buckle with this body 30.The end face of these lens 10 is provided with reflective surface 11, preferred, the taper seat (as shown in Figure 3) that this reflective surface 11 protrudes out towards described LED light source plate 20 for middle part.These lens 10 are made by transparent or semitransparent material, and part light can penetrate from the top of these lens 10 through reflective surface 11.The bottom of these lens 10 is provided with accepting groove 12, and this caustic surface 121 is arranged in this accepting groove 12, and this caustic surface 121 is Fresnel Lenses surface.This caustic surface 121 for light that described LED light source 22 is sent towards these reflective surface 11 refractions, this reflective surface 11 for by most of light towards these lens 10 sidewall reflects, light is through the outside of rear this all-round smooth LED lamp 100 of direct directive of these lens 10.Between this caustic surface 121 and this accepting groove inwall 123, be provided with changeover portion 122, this changeover portion 122 is for the sidewall refraction towards these lens 10 by light.The inwall of this changeover portion 122 is the annular wall configuration that relatively this light source board 20 tilts, and by the setting at angle of inclination, makes that these LED light sources 22 are that send, the light major part of these changeover portion 122 inwalls of directive is towards the sidewall refraction of these lens 10.
During work, the light overwhelming majority that these LED light sources 22 send is irradiated on the caustic surface 121 of these lens 10, on the reflective surface 11 of these light that are radiated at this caustic surface 121 these lens 10 of multiple aggregation directive after refraction.Because these lens 10 are made by transparent or trnaslucent materials, therefore there is certain transmission capacity, make a light part that gathers this reflective surface 11 penetrate lens 10 through this reflective surface 11, make these all-round smooth LED lamp 100 tops have light to penetrate; Meanwhile, because this reflective surface 11 has reflective function, make another part light that gathers this reflecting surface 11 towards these lens 10 sidewall bottom reflection, so just can make beam angle reach 320 degree.Owing to being provided with changeover portion 122 between this caustic surface 121 and this accepting groove inwall 123, like this, the light sending from LED light source 22 can arrive these lens 10 sidewalls through refraction being irradiated to this changeover portion 122, and this part light is by the top-direction outgoing to these lens 10.
In sum, this all-round smooth LED lamp 100 to these reflective surface 11 back reflections to this lens 10 sidewalls bottoms, makes this all-round smooth LED lamp 100 have advantages of that lighting angle is large by the light-ray condensing that caustic surface 121 is set at lens 10 described LED light source 22 is sent.And, because these lens 10 can be realized wide-angle luminous intensity distribution, at needs, bulb housing is not set in addition, make this LED lamp 100 have advantages of simple in structure.Due to the setting of these lens 10, make this all-round smooth LED lamp 100 a plurality of for the side substrate of LED light source is installed without arranging, avoided the light that sends dazzling, make this all-round smooth LED lamp 100 there is good visual effect, simple in structure.Because these lens are transparent or trnaslucent materials is made, like this, this all-round smooth LED lamp top has light and penetrates, and makes these all-round smooth LED lamp 100 tops not have blackening and occurs.Owing to being provided with changeover portion 122 between this caustic surface 121 and this accepting groove inwall 123, make the light that is irradiated to this changeover portion 122 to arrive these lens 10 sidewalls through refraction, avoid this part light to be blocked and cannot penetrate by body, improved light extraction efficiency.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of making within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included in the scope of protection of the invention.
