Abstract
The utility model relates to a light spot adjusting structure for an LED lamp, which can adjust the distance between a light spot and a lamp by adjusting the distance between a first optical component (20) and a second optical component (30). Therefore, the light spot adjusting structure for the LED lamp has the advantages of capabilities of adjusting the light spot position of the lamp and meeting different lighting requirements.
Description
Technical field
The utility model relates to the LED lighting field, mentions a kind of LED light fixture hot spot adjustment structure especially.
Background technology
LED is the development trend of following lighting field as a kind of novel green light source product, and a lot of conventional lamp all changes into and adopts LED as light source, has the advantage of energy-conserving and environment-protective.All can assemble beam condensing unit on a lot of LED light fixtures and make light-ray condensing, such as optical lens, to improve the brightness of illumination light class, such as LED Down lamp, portable electric torch etc.These LED light fixtures are at the beginning of making; Optical lens and led light source just are fixed on lamp body inside; Therefore these light fixtures the hot spot that light fixture light assembled occurs through regular meeting in use and do not shine on the photographed object, do not reach illuminating effect clearly, trace it to its cause; Be because the distance setting of optical lens and led light source is unreasonable, make hot spot that optical lens is gathered into can not satisfy different lighting requirements with distance between the light fixture.
The utility model content
To the deficiency that above-mentioned prior art exists, the purpose of the utility model provides a kind of LED light fixture hot spot adjustment structure, and it has can regulate the light fixture facula position, satisfies the advantage of different lighting requirements.
To achieve these goals, the technical scheme that the utility model adopted is: LED light fixture hot spot adjustment structure comprises the tubular lamp body; Be positioned at lamp body inner first optics and second optics; And the cover that is covered in the lamp body peristome, said cover has column jecket, and said lamp body is placed on the said column jecket; It is characterized in that the barb of the column jecket outer wall of said cover is connected in the cannelure of said lamp body inwall; Said first optics is connected through threaded engagement with the column jecket of said cover; Guide rail on the said first optics outer wall is positioned at the guide groove of said lamp body inwall; Second optics fixedly installs in lamp body.
Preferably, said first optics is a led light source, and said second optics is a collector lens.
Preferably, said second optic stationary is in the column jecket inner ring of said cover.
Preferably, said first optics is a collector lens, and said second optics is a led light source.
Preferably, said second optic stationary is on said lamp body inwall.
The utility model compared with prior art has following advantage: be connected through threaded engagement with the column jecket of said cover through first optics; Guide rail on the said first optics outer wall is positioned at the guide groove of said lamp body inwall; Rotate cover like this, make itself and lamp body that rotation relatively take place, the column jecket of cover also can rotate thereupon; First optics also has the trend of rotation thereupon; But because the guide rail of first optics is positioned at the guide groove of said lamp body inwall, first optics can not be rotated, therefore under the column jecket and the threaded engagement between first optics of cover; First optics meeting moving axially along the difference screw thread; Realize regulating the distance between first optics and second optics, therefore can regulate the hot spot of light fixture formation and the distance between the light fixture indirectly, promptly can satisfy various lighting requirement.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is another structural representation of the utility model;
Fig. 3 is a structural representation again of the utility model.
Among the figure: 10, lamp body 20, first optics 30, second optics
40, cover 50, column jecket 60, barb
70, cannelure 80, guide rail 90, guide groove.
The specific embodiment
The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.
Embodiment, see that Fig. 1 is to shown in Figure 3: the utility model is a kind of LED light fixture hot spot adjustment structure, comprises tubular lamp body 10; Be positioned at first optics 20 and second optics 30 of lamp body 10 inside; And the cover 40 that is covered in lamp body 10 peristomes, said cover 40 has column jecket 50, and said lamp body 10 is placed on the said column jecket 50; It is characterized in that the barb 60 of column jecket 50 outer walls of said cover 40 is connected in the cannelure 70 of said lamp body 10 inwalls; The column jecket 50 of said first optics 20 and said cover 40 is connected through threaded engagement; Guide rail 80 on said first optics, 20 outer walls is positioned at the guide groove 90 of said lamp body 10 inwalls; Second optics 30 fixedly installs in lamp body 10.The column jecket 50 of the utility model through first optics 20 and said cover 40 is connected through threaded engagement; Guide rail 80 on said first optics, 20 outer walls is positioned at the guide groove 90 of said lamp body 10 inwalls; Rotate cover 40 like this, make itself and lamp body 10 that rotation relatively take place, the column jecket 50 of cover 40 also can rotate thereupon; First optics 20 also has the trend of rotation thereupon; But because the guide rail 80 of first optics 20 is positioned at the guide groove 90 of said lamp body 10 inwalls, first optics 20 can not be rotated, therefore under the column jecket 50 and the threaded engagement between first optics 20 of cover 40; First optics, 20 meetings moving axially along the difference screw thread; Realize regulating the distance between first optics 20 and second optics 30, therefore can regulate the hot spot of light fixture formation and the distance between the light fixture indirectly, promptly can satisfy various lighting requirement.
In the LED light fixture, for collected light becomes hot spot, will inevitably have led light source and collector lens, regulate the purpose that the distance between led light source and the collector lens just can realize regulating facula position.But in order to simplify fitting structure; General all is the position of regulating one of them; Regulate distance between the two, collector lens is fixed so that the position of regulating led light source is arranged, perhaps regulate position and the fixed such two kinds of selections of led light source of collector lens.According to above-mentioned explanation; The utlity model has two sets of plan: the first, as shown in Figure 1, said first optics 20 is a led light source; Said second optics 30 is a collector lens; Said second optics 30 is fixed in column jecket 50 inner rings of said cover 40, make between the column jecket 50 of led light source and cover 40 through threaded engagement, and led light source cooperates with guide groove 90 on the lamp body 10 through the guide rail 80 on it; Rotation cover 40 just can drive led light source and move, and regulates the distance between led light source and the collector lens; It two is that as shown in Figure 2, said first optics 20 is a collector lens; Said second optics 30 is a led light source; Said second optics 30 is fixed on said lamp body 10 inwalls, make between the column jecket 50 on collector lens and the cover 40 through threaded engagement, and collector lens cooperates with guide groove 90 on the lamp body 10 through the guide rail 80 on it; Rotation cover 40 just can drive collector lens and move, and regulates the distance between collector lens and the led light source.No matter which kind of scheme can realize regulating the effect of distance between the two,, satisfy the illumination of multiple demands of different to regulate the distance between light fixture hot spot and the light fixture.
The LED light fixture hot spot adjustment structure of the utility model, it has can regulate the light fixture facula position, satisfies the advantage of different lighting requirements.
