Abstract

The utility model belongs to the technical field of daily illumination appliances, and aims at providing an LED bulb capable of increasing the illumination area. The adopted technical scheme is as follows: the LED bulb comprises a lamp cap, a lampshade, a plurality of LEDs and a plurality of circuit boards, wherein the bottom end of the lampshade is fixedly arranged at the top of the lamp cap, the plurality of circuit boards are fixedly arranged in the lampshade and electrically connected with the lamp cap, the plurality of circuit boards are connected in an end-to-end manner so as to form a multi-pyramid or a multi-truncated-pyramid shape, and the plurality of LEDs are distributed on the surfaces of the circuit boards. The LED bulb has the benefits of being capable of fully utilizing the illumination characteristic of the LEDs so as to increase the illumination area to the maximum extent, and achieving the purpose of saving energy resources by utilizing LED light sources.

Description

The LED bulb
Technical field
The utility model relates to a kind of LED bulb, belongs to normal lighting apparatus technical field.
Background technology
Present led Assembled lamp, the panel that the led lamp is installed generally is plane or right circular cylinder body, because the led fluorescent lamp is by being welded on the lamp that printed circuit board (PCB) is combined into by a lot of single led lamps, the lighting angle characteristics of led are to be not more than 120 degree, and existing printed substrate all is the plane, so the lighting area that the led lamp on plane wants to reach certain must be raised the size of lamp to increase scattering of light.And the led Assembled lamp of cylinder is because printed circuit board (PCB) is upright, above the led lamp is welded on after, go up several rows' led lamp most because the problem of lighting angle does not have practical function in actual illumination.So increased production cost, caused energy waste.
Summary of the invention
The technical problems to be solved in the utility model is a kind of LED bulb that can increase lighting area.
In order to solve the problems of the technologies described above, the utility model adopts following embodiment:
A kind of LED bulb, comprise lamp holder, lampshade, LED and circuit board, lampshade lampshade bottom is fixed on the top of lamp holder, described circuit board is fixed in the lampshade, circuit board is electrically connected with lamp holder, described circuit board is a plurality of, and the first place joins each other, constitutes polygonal pyramid body or polygonal pyramid platform shape; Described LED is a plurality of, and is distributed on each face of circuit board.
Among the utility model embodiment, described circuit board constitutes triangular cone, rectangular pyramid body, triangular frustum or tetragonous cone table shape.
Among the utility model embodiment, the drift angle angle that adjacent two seamed edges of described polygonal pyramid body or polygonal pyramid platform intersect is 30-60 °.
Among the utility model embodiment, lampshade is triangular cone, rectangular pyramid body, triangular frustum or tetragonous cone table shape.
Among the utility model embodiment, described circuit board material is PCB.
The beneficial effects of the utility model are: can make full use of the luminous characteristics of led, increase lighting area to greatest extent, and utilize the led light source, thereby reach the purpose of energy savings.
