Abstract
The utility model discloses a light-emitting diode (LED) lamp which comprises an LED lamp tube, a connection piece and a plurality of circuit boards. The circuit boards are installed on the connection piece, the LED lamp tube is installed on the circuit boards, the plurality of circuit boards are circumferentially and evenly distributed on the lower surface of the connection piece at intervals, light reflection strips are arranged between the adjacent circuit boards, a circumferential light reflection cover is further arranged on the lower surface of the connection piece, and the light reflection cover opens downwards and is located on the outsides of the circuit board. Due to the fact that the plurality of circuit boards are circumferentially and evenly distributed on the connection piece, the lighting range is expanded. Due to the light reflection strips and the light reflection cover, the LED light is even after multiple reflection, the angle is good, and the light emitting efficiency is high.
Description
Technical field
The utility model relates to LED lamp technical field, relates in particular to a kind of high light efficiency, LED lamp that illumination zone is large.
Background technology
In recent years, because the development of LED industry is rapid, LED light fixture progressively replaces traditional lighting, and LED chip applies to room lighting field as light source to be developed fast, and people a kind ofly can overcome the difficult problem that LED light distribution angle is little constantly exploring.But, if met at present the luminous complex structure often of wide-angle in LED lighting, and the distribution of light unusual inequality again.Want to make the LED lamp can replace incandescent, just must overcome that LED lighting angle is little, the problem of non-uniform light.
Utility model content
The utility model is mainly to solve existing technical problem in prior art, thereby good, the high light efficiency of a kind of lighting angle, the LED lamp that illumination zone is large are provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
LED lamp of the present utility model, comprise LED fluorescent tube, connector and multiple circuit board, described circuit board is arranged on described connector, described LED fluorescent tube is arranged on described circuit board, the circumferentially spaced lower surface that is distributed on described connector of multiple described circuit boards, is provided with reflecting strips between described adjacent circuit board, and the lower surface of described connector is also provided with a circumference type reflection shield, Open Side Down for described reflection shield, and be positioned at the outside of described circuit board.
Further, also comprise a Transparent lamp shade, described Transparent lamp shade is fixed on the lower surface of described connector, and is positioned at the outside of described reflection shield.
Further, between described circuit board and described connector, be also provided with heat pipe.
Further, described connector outer surface is provided with radiating fin, described radiating fin be shaped as triangle.
Compared with prior art, the utility model has the advantage of: by multiple circuit boards are circumferentially distributed on connector, expanded its illumination zone, and owing to being provided with reflecting strips and reflection shield, LED light is after multiple reflections, luminous even, angle is good, and luminous efficiency is high.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of LED lamp of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult shown in Fig. 1, LED lamp of the present utility model, comprise LED fluorescent tube 2, connector 4 and multiple circuit board 3, circuit board 3 is arranged on connector 4, and LED fluorescent tube 2 is arranged on circuit board 3, the circumferentially spaced lower surface that is distributed on connector 4 of multiple circuit boards 3, between adjacent circuit board 3, be provided with reflecting strips 5, and the lower surface of connector 4 is also provided with a circumference type reflection shield 6, Open Side Down for reflection shield 6, and be positioned at the outside of circuit board 3, the opening angle of reflection shield 6 is preferably 150.
LED lamp of the present utility model also comprises a Transparent lamp shade 1, and Transparent lamp shade 1 is fixed on the lower surface of connector 4, and is positioned at the outside of reflection shield 6.In lampshade 1, can fill thermal conductivity gas, as helium etc., lampshade 1 is set not only can prevent dust, also can dispel the heat by thermal conductivity gas.Between this circuit board 3 and connector 4, be also provided with heat pipe 7.Connector 4 outer surfaces are provided with radiating fin 8, radiating fin 8 be shaped as triangle, the heat of LED fluorescent tube 2 is passed on connector 4 by heat pipe 7, and dispels the heat by the radiating fin 8 on connector 4, effectively improve the service life of LED fluorescent tube 2, reduced maintenance cost.
The utility model, by multiple circuit boards are circumferentially distributed on connector, has expanded its illumination zone, and owing to being provided with reflecting strips and reflection shield, LED light is after multiple reflections, and luminous evenly angle is good, and luminous efficiency is high.
Above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
