The utility model discloses be equipped with the spotlight lid on the lamp cup, the middle part of spotlight lid is equipped with the hemisphere face, form the convex lens effect, these convex lens are just in time just to the LED lamp plate, the direct light that sends the LED lamp plate carries out spotlight, the spotlight effect is very good, and simultaneously, the lateral surface of spotlight lid is the convex arc face, the inboard concave arc face that is, the convex arc face is corresponding with the lamp cup inner wall, get into in the convex arc face through the light after the reflection of light of lamp cup inner wall, jet out through the concave arc face after the refraction, play the effect of spotlight equally.
Description
Technical field
This utility model relates to a kind of LED, is specifically related to a kind of LED bulb with light-focusing function.
Background technology
Along with the development of science and technology, lighting is also weeded out the old and bring forth the new constantly, is developed to fluorescent daylight fluorescent tube, the appearance of up-to-date LED lamp from traditional electric filament lamp, and wherein, LED lamp is because having the advantage such as energy-saving and environmental protection, length in service life and expanded application.Existing LED bulb includes that lampshade, Lamp cup and lamp holder, LED lamp panel and driver are arranged on bottom Lamp cup, and LED bulb sends light and penetrates from lampshade through the reflection of Lamp cup, and the light range of injection is relatively wide, irradiates and does not concentrates, it is impossible to reaches good spotlight effect.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of LED bulb with good spotlight effect.
This utility model solves its technical problem and be the technical scheme is that
A kind of LED bulb with light-focusing function, including LED lamp panel, driver and for placing the Lamp cup of LED lamp panel, described Lamp cup is provided with optically focused light cover, described optically focused light cover is bowl-shape, the lateral surface of optically focused light cover is convex globoidal, exterior bottom is the plane corresponding with LED lamp panel, and the medial wall of optically focused light cover is cancave cambered surface, and the middle part of described cancave cambered surface is provided with protrusion hemisphere face.
In this utility model, the upwardly recessed formation in the middle part groove of described plane, the both sides of groove are provided with breach.
In this utility model, the periphery of described optically focused light cover is provided with the connection limit being connected with Lamp cup peristome.
In this utility model, it described hemisphere face is non-smooth surface.
The beneficial effects of the utility model are: this utility model is provided with optically focused light cover on Lamp cup, the middle part of optically focused light cover is provided with hemisphere face, form convex lens effect, this convex lens is the most just to LED lamp panel, the light directly sent LED lamp panel carries out optically focused, spotlight effect is the best, simultaneously, the lateral surface of optically focused light cover be convex globoidal, inner side be cancave cambered surface, convex globoidal is corresponding with Lamp cup inwall, light after Lamp cup inwall is reflective enters in convex globoidal, penetrates through cancave cambered surface, play the effect of optically focused equally after refraction.This utility model can carry out optically focused to LED lamp panel and sky light thereof, and effect is better than general convex lens spotlight effect.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present embodiment；
Fig. 2 is the structural representation of optically focused light cover；
Fig. 3 is the top view of Fig. 2；
Fig. 4 is the upward view of Fig. 2.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, a kind of LED bulb with light-focusing function that the present embodiment is provided, including LED lamp panel 1, driver 2 and for placing the Lamp cup 3 of LED lamp panel 1, described Lamp cup 3 is provided with optically focused light cover 4, described optically focused light cover 4 is bowl-shape, the lateral surface of optically focused light cover 4 is convex globoidal 41, exterior bottom is the plane 42 corresponding with LED lamp panel 1, the medial wall of optically focused light cover 4 is cancave cambered surface 43, the thickness of optically focused light cover 4, this thickness progressive additive from outside to inside is constituted between convex globoidal 41 and cancave cambered surface 43.The middle part of described cancave cambered surface 43 is provided with protrusion hemisphere face 44, and hemisphere face 44 constitutes convex lens effect, and this hemisphere face 44 is placed exactly in the surface of LED lamp panel 1, the most of light-ray condensing that can will send in LED lamp panel 1.
As preferred embodiment, because the lamp bead in LED lamp panel 1 raises up, for ease of the upwardly recessed formation in the middle part groove 45 of plane 42 described in fixing LED lamp panel 1, the lamp bead in LED lamp panel 1 is placed exactly in groove 45, the both sides of groove 45 are provided with breach 46, for through electric wire and heat radiation.
Further, the periphery of described optically focused light cover 4 is provided with the connection limit 47 being connected with Lamp cup 3 peristome, and described connection limit 47 is connected with Lamp cup 3 by glue.For adapting to part great power LED, the change of the irradiating angle that hemisphere face 44 spherical radius reaches along with actual operation requirements and change, its Changing Pattern is along with the increase of irradiating angle increases, and the surface of described hemisphere face 44 is non-smooth surface, it is arranged above with multiple small sphere of exterior rearview, the quantity of small sphere of exterior rearview increases along with the increase of spherical radius, described irradiating angle refers to the key lighting angle that light is mapped on foremost object, the lighting angle of main flow is 120 ° at present, 10 ° can be gathered into by this hemisphere face 44 and small sphere of exterior rearview, 12 °, 24 °, 36 °, 38 °, the use angles with directional lighting function such as 60 °, range is wider.
The foregoing is only preferred embodiments of the present utility model, as long as realizing within the technical scheme of this utility model purpose broadly falls into protection domain of the present utility model with essentially identical means.
