Abstract
The utility model relates to a kind of Large-angle emission LED lamp, comprise base, described base center upper portion is provided with pedestal, the top back-off of described base has outer cover, column is fixed with in the middle part of described pedestal, described pedestal and base top are provided with circuit board, described circuit board is provided with lower LED bulb, described column is provided with LED bulb, reflector is provided with between described outer cover and circuit board, two various level LED bulb are provided with in the space of the utility model between base and outer cover, namely the lower LED bulb being arranged on the upper LED bulb on column and being arranged on pedestal and base, both emit beam.Be provided with reflector between the intrados of outer cover and circuit board, one end of reflector on the intrados of outer cover, the other end and circuit board contacts, like this, the light that the lower LED bulb of a part sends is reflected by reflector, expands lighting angle of the present utility model, defines the light of wide-angle.
Description
Technical field
The utility model belongs to a kind of technical field of lighting fixtures, specifically relates to a kind of Large-angle emission LED lamp.
Background technology
At present, adopt the illuminating lamp of LED light source by market extensive use.In existing LED bulb, LED light emission direction be all be generally set to contrary with lamp holder.Light emission direction due to LED is generally forward, is subject to the restriction of its lighting angle, and existing LED bulb luminescence only has a taper angle, the dark at its lamp holder place, can not be the same as with fluorescent lamp bulb all directions uniformly light-emitting as traditional incandescent light bulb.
In order to realize the wide-angle omnidirectional lighting of LED, industry is normally arranged light source to and is multiplely had (as plane and vertical plane) in the plane of different angles, such as, publication date is on September 22nd, 2010, the Chinese utility model patent of number of patent application 201020026276.4 discloses a kind of Polyhedral LED lamp, its polyhedron is located in bulb housing, multiple LED is located at this polyhedral each side and top, although this method can reach larger light distribution angle, but still there is following defect: the light emission direction of this LED is set to forward and towards side, therefore less light is only had can to irradiate towards the lamp holder of this LED lamp, make whole lamp wiring skewness, the wide-angle being difficult to realize more than 300 degree is luminous.
Utility model content
The technical problems to be solved in the utility model is to provide the simple Large-angle emission LED lamp of a kind of structure.
Content of the present utility model comprises base, described base center upper portion is provided with pedestal, the top back-off of described base has outer cover, column is fixed with in the middle part of described pedestal, described pedestal and base top are provided with circuit board, described circuit board is provided with lower LED bulb, and described column is provided with LED bulb, is provided with reflector between described outer cover and circuit board.
The reflective surface of described reflector is arc.
The beneficial effects of the utility model are, are provided with two various level LED bulb in the space of the utility model between base and outer cover, and the lower LED bulb being namely arranged on the upper LED bulb on column and being arranged on pedestal and base, both emits beam.Be provided with reflector between the intrados of outer cover and circuit board, one end of reflector on the intrados of outer cover, the other end and circuit board contacts, like this, the light that the lower LED bulb of a part sends is reflected by reflector, expands lighting angle of the present utility model, defines the light of wide-angle.
The utility model is LED bulb on column top is also provided with, and upper LED bulb can fill up light that the lower LED bulb of a part sends by the problem reflected, and intensity of illumination is constant.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In the drawings, LED bulb on 1 outer cover, 2 reflectors, 3 circuit boards, 4 pedestals, 5 bases, 6 times LED bulb, 7 columns, 8.
Detailed description of the invention
As shown in drawings, the utility model comprises base 5, described base 5 center upper portion is provided with pedestal 4, the top back-off of described base 5 has outer cover 1, be fixed with column 7 in the middle part of described pedestal 4, described pedestal 4 and base 5 top are provided with circuit board 3, and described circuit board 3 is provided with lower LED bulb 6, described column 7 is provided with LED bulb 8, between described outer cover 1 and circuit board 3, is provided with reflector 2.
The reflective surface of described reflector 2 is arc.
Be provided with two various level LED bulb in the space of the utility model between base 5 and outer cover 1, the lower LED bulb 6 being namely arranged on the upper LED bulb 8 on column 7 and being arranged on pedestal 4 and base 5, both emits beam.Reflector 2 is provided with between the intrados of outer cover 1 and circuit board 3, one end of reflector 2 is on the intrados of outer cover 1, the other end contacts with circuit board 3, like this, the light that the lower LED bulb 6 of a part sends is reflected by reflector 2, expand lighting angle of the present utility model, define the light of wide-angle.
The utility model is also provided with LED bulb 8 on column 7 top, and upper LED bulb 8 can fill up light that the lower LED bulb 6 of a part sends by the problem reflected, and intensity of illumination is constant.
