Background technology
Ceiling light, refers to the lighting being embedded into light in ceiling and irradiating downwards.This hidden the putting property light fixture being flush-mounted in ceiling inside, all light projects all downwards, belongs to direct luminous intensity distribution.With different reflectors, eyeglass, shutter, bulb, different light effects can be obtained.Ceiling light is widely used in the use as accent light such as market, hospital, school, large supermarket, office space, high-end residential, brightening, beautifies the environment, and is also life increasing colour.
Existing ceiling light is directly embedded in ceiling, and after installation, light direction of illumination is fixed, and can not change.CN102418887A patent document discloses a kind of Down lamp, is embedded in ceiling by jump ring by whole light fixture, and lamp is fixing to be irradiated downwards.CN203517369U patent document discloses a kind of light fixture, and its inside has the guide-lighting ring of high reflectance, and the light projected to make the light-emitting device of light fixture, in ground place, has high illumination and gradually layer to overflow the double effects of light mixed light.But the irradiating angle of the lighting of above patent document is non-adjustable, and cost is high.
Utility model content
For the weak point that prior art exists, the utility model proposes a kind of ceiling light, the direction of illumination of light source is adjustable, and uses Fresnel Lenses to reduce the angle of emergence of ceiling light, and then increases the irradiation distance of ceiling light.
The utility model adopts following technical scheme:
A kind of ceiling light, it comprises annular mount pad and lamp body, and lamp body is arranged with in annular mount pad, is rotationally connected with annular mount pad; Lamp body comprises annular brace seat, Fresnel Lenses, light source board, heat dissipation base and tubular outer cover; Be provided with heat dissipation base in tubular outer cover, light source board is arranged on heat dissipation base, and the exiting surface of light source board is towards Fresnel Lenses; Fresnel Lenses is positioned at the opening part of tubular outer cover, is arranged on annular brace seat, Fresnel Lenses convex surface facing light source board; Tubular outer cover is fixed on the upper port of annular brace seat.
Further, heat dissipation base is embedded in tubular outer cover.
Further, the radiating ribs of integrated injection molding is provided with along the outer wall of described tubular outer cover.
Further, annular mount pad bilateral symmetry is provided with mounting bracket, and described mounting bracket is spring(-supported) mount.
Further, light source board center is provided with multiple LED light source.
The lamp body of ceiling light and annular mount pad separate by the utility model, and lamp body and annular mount pad are rotatably assorted.After ceiling light is installed, annular mount pad is fixing, and lamp body can rotate relative to annular mount pad on the ceiling, regulates the direction of illumination of ceiling light.Light of the present utility model through Fresnel Lenses refractive illumination out, based on the characteristic of Fresnel Lenses itself, this utility model shooting angle diminishes, and irradiation distance becomes large, can be applicable to the lighting fields such as market, large supermarket, warehouse.

Detailed description of the invention
For further illustrating each embodiment, the utility model provides accompanying drawing.These accompanying drawings are a part for the utility model disclosure, and it is mainly in order to illustrate embodiment, and the associated description of description can be coordinated to explain the operation principles of embodiment.Coordinate with reference to these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantage of the present utility model.Assembly in figure not drawn on scale, and similar element numbers is commonly used to assembly like representation class.
Now with detailed description of the invention, the utility model is further illustrated by reference to the accompanying drawings.
Consult shown in Fig. 1 to Fig. 5, the ceiling light of the preferred embodiment of the utility model, it comprises annular mount pad 1 and lamp body, and lamp body comprises annular brace seat 2, Fresnel Lenses 3, light source board 4, aluminum substrate 5, tubular outer cover 6.Wherein, lamp body is positioned at inside annular mount pad 1, and both are rotationally connected.
Consult shown in Fig. 1, annular mount pad 1 bilateral symmetry is provided with through hole, and annular brace seat 2 bilateral symmetry is provided with two projecting blocks, and projecting block is also provided with through hole.Use screw column to coordinate fixing by the through hole on annular mount pad 1 and the through hole on annular brace seat 2, annular brace seat 2 relative to annular mount pad 1 centered by screw column, can do partial circular motion.
Consult shown in Fig. 5, be provided with aluminum substrate 5 in tubular outer cover 6, aluminum substrate 5 and tubular outer cover 6 are fixed together.Light source board 4 is arranged on aluminum substrate 5, and the exiting surface of light source board 4 is towards Fresnel Lenses 3.Tubular outer cover 6 is fixedly mounted on the upper port of annular brace seat 2, and Fresnel Lenses 3 is positioned at the opening part of tubular outer cover 6, is fixedly mounted on annular brace seat 2, and the direction convex surface facing light source board 4 of Fresnel Lenses 3.The aluminum substrate 5 of this embodiment is embedded in tubular outer cover 6, and aluminum substrate 5 and tubular outer cover 6 are combined into one, and are conducive to the conduction of heat.
Consult shown in Fig. 6, the illumination that light source board 4 sends is mapped on Fresnel Lenses 3, according to the optical characteristics of Fresnel Lenses 3, optical surface due to Fresnel Lenses 3 has multiple cannelure, illumination reflects after being mapped to Fresnel Lenses 3, major part light shines out along direction that is vertical and light source board 4, and namely most of light penetrates with directional light.Compared with prior art, Fresnel Lenses decreases the light collecting in focus, and divergent rays is tailed off, and light is more concentrated, and the angle of emergence of the light that light source board 4 sends reduces, and namely reduces the angle of emergence of ceiling light.Because the light of ceiling light is more concentrated, irradiation distance will increase.
Aluminum substrate 5 is also tubular structure, and aluminum substrate 5 embeds and is arranged in tubular outer cover 6, and light source board 4 is arranged on position at the bottom of the cylinder of aluminum substrate 5, and the exiting surface of light source board 4 is towards Fresnel Lenses 3.At the bottom of the cylinder of the aluminum substrate 5 of this embodiment and light source board 4 be all provided with corresponding screw hole, use screw to be fixedly connected with aluminum substrate 5 by light source board 4.
