Description
Technical field
The present invention relates to the LED lighting, particularly a kind of large-angle LED lamp.
Background technology
At present, the illuminating lamp that adopts led light source is by the market extensive use.In the existing LED bulb, the LED light emission direction generally all be set to opposite with lamp holder.Because the light emission direction of LED generally is forward, receives the restriction of its lighting angle, existing LED bulb is luminous to have only a taper angle, and the light at its lamp holder place is darker, can not be as traditional incandescent light bulb and fluorescent lamp bulb to all directions uniformly light-emitting.
In order to realize the wide-angle omnidirectional lighting of LED lamp; Industry is normally arranged light source to (like plane and vertical plane) on a plurality of planes with different angles, and for example, open day is on September 22nd, 2010; The Chinese utility model patent of number of patent application 201020026276.4 has disclosed a kind of polyhedron LED light fixture; Its polyhedron is located in the bulb shell, and a plurality of LED are located at this polyhedral each side and top, though this method can reach bigger luminous intensity distribution angle; But still have following defective: the light emission direction of this LED is set to forward and towards side; Therefore have only less light to make to be difficult to realize that the above wide-angle of 300 degree is luminous by whole lamp wiring skewness towards the lamp holder irradiation of this LED light fixture.
Summary of the invention
In view of this, be necessary to provide a kind of simple in structure, can realize the large-angle LED lamp that wide-angle is luminous.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of large-angle LED lamp comprises lamp holder, bulb shell, substrate and led light source, and this bulb shell comprises roof and sidewall; The bottom of this bulb shell side wall is arranged on the top that connects this lamp holder; Also comprise reflecting component, this reflecting component is fixed on the top surface of being located at this lamp holder, and this substrate is located at the roof of this bulb shell; Said led light source is arranged on this substrate and towards this reflecting component setting; The width of this bulb shell roof is greater than the width of its sidewall, and the area of this bulb shell roof is greater than the area of this substrate, and the light that this reflecting component is used for said led light source is sent is towards this roof reflection.
Compared with prior art, the invention provides a kind of large-angle LED lamp, it is arranged on led light source on the substrate at its bulb shell top, and therefore light direction makes this that stronger intensity of illumination arranged below the lamp holder towards this lamp holder.This bulb shell comprises roof and sidewall, and this roof area is greater than the area of this substrate.Also be provided with reflecting component that should led light source, so the light that this led light source sends will reflex to this bulb shell roof by this reflecting component, making also has stronger distribution of light on the roof of this bulb shell, thereby has increased the distribution of light scope on this bulb shell.Large-angle LED lamp of the present invention has guaranteed that whole lamp wiring is evenly distributed, and has realized the wide-angle illumination greater than 300 degree, has simple in structurely, can realize the advantage that wide-angle is luminous.
