Abstract
The utility model provides an anti-dazzle light-emitting diode (LED) spot lamp, which is used for weakening dazzle of the spot lamp and reducing irritation to human eyes. The anti-dazzle LED spot lamp comprises a transparent lampshade. The lampshade is a spherical lampshade and comprises a lampshade mouth. A transparent plate is fixed at the lampshade mouth. A concave lens is arranged on the transparent plate and is arranged right above an LED lamp. The transparent lamp is in threaded connection with the lampshade. Since one transparent plate is arranged on the lampshade, one concave lens is arranged on the transparent plate and the concave lens is arranged right above the LED lamp, by adopting the structure, brightest light emitted by the LED lamp, i.e. the light which is not reflected by a reflecting surface and directly goes out can be dispersed by the concave lens, the sphericity of a solid angle of the LED lamp is obviously expanded and the dazzle factor is weakened. Therefore, the dazzle is effectively prevented to some extent and the irritation of the lamp to the human eyes is reduced.
Description
Technical field
The utility model relates to a kind of LED lighting device, particularly relates to the LED shot-light.
Background technology
The lamp body of existing a kind of LED shot-light is fixed on the clamp bracket through adjustment screw, and lamp body is regulated through adjustment screw and looked up or depression angle, promptly realizes the rotation of lamp body.The LED shot-light comprises Transparent lamp shade, and the LED shot-light therefore in order to prevent dazzle, has the shot-light of the lampshade that adopts honeycomb because the direction of illumination trend of light is consistent.But the lampshade of honeycomb has weakened the uniformity of light greatly, and the function of shot-light is weakened, and therefore this mode is not that most of producers adopt.
The utility model content
The utility model purpose provides a kind of LED shot-light of anti-dazzle, is used to weaken the dazzle of shot-light, reduces the stimulation to human eye.
In order to solve above-mentioned technical problem, the utility model proposes a kind of LED shot-light of anti-dazzle, comprises Transparent lamp shade, and
Said lampshade is the sphere lampshade, and it comprises the lampshade mouth, is fixed with a transparent panel at lampshade mouth place;
Transparent panel is provided with concavees lens, concavees lens be positioned at the LED lamp directly over;
Transparent panel and lampshade are through being threaded.
Preferably: with the LED lamp is that conical tip, said concavees lens are that the drift angle of the circular cone of crown is 60 °～90 °.Since the high light that the LED lamp sends can the surface of sphere at 3-dimensional irradiation angle be generally in the scope of π/3～pi/2, it can convert into the scope of above-mentioned circular cone drift angle.
Preferably: the drift angle of said circular cone is 60 °.
The beneficial effect of the utility model:
Compare prior art, the utility model is provided with a transparent panel on lampshade, on transparent panel, has established concavees lens; These concavees lens be positioned at the LED lamp directly over, the high light that this structure can make that the LED lamp sends, i.e. through the reflective surface reflection and the direct light of outgoing; Disperseed by concavees lens, the surface of sphere of its solid angle obviously enlarges, and the dazzle factor has weakened; Therefore, can effectively prevent dazzle to a certain extent, reduce the stimulation of light fixture human eye.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is a schematic diagram.
The specific embodiment
The utility model proposes a kind of LED shot-light of anti-dazzle, comprises Transparent lamp shade, and lampshade is the sphere lampshade, and it comprises the lampshade mouth, is fixed with a transparent panel at lampshade mouth place; Transparent panel is provided with concavees lens, concavees lens be positioned at the LED lamp directly over; Transparent panel and lampshade are through being threaded.
Through embodiment the technical scheme of the utility model is elaborated below.
The example structure of the utility model is as shown in Figure 1, is provided with LED lamp 3 and aluminium base 2 in the housing 1, and LED lamp 3 is located on the aluminium base 2, is provided with Transparent lamp shade 5 at the front end of housing 1.Lampshade 5 is the sphere lampshade, and it comprises the lampshade mouth, and the place is fixed with transparent panel 4 at the lampshade mouth; Transparent panel 4 is provided with concavees lens 6, concavees lens 6 be positioned at LED lamp 3 directly over.Transparent panel 4 is connected through screw connection structure 7 with lampshade 5.Around LED lamp 3, establish reflective surface 8.Referring to Fig. 2, be that conical tip, concavees lens 6 are that the vertex angle theta of the circular cone of crown is 60 °～90 ° with LED lamp 3, among Fig. 2, the vertex angle theta of circular cone is preferably 60 °.Since the high light that the LED lamp sends can the surface of sphere at 3-dimensional irradiation angle be generally in the scope of π/3～pi/2, it can convert into the scope of above-mentioned circular cone drift angle.
Claims (3)
