Abstract

The utility model relates to an LED (light-emitting diode) lamp, which comprises a lamp cap, a lamp head, a lamp head shell, a lamp shade, wherein the lamp head and the lamp head shell are integrally formed with the lamp cap; the lamp shade is buckled in a caulking groove of the lamp head shell; the top of the lamp head shell is in a platform form; a PCB (printed circuit board) is arranged on the platform; the PCB is provided with a plurality of LED lamps; and a trumpet-shaped inner cover with an upper big opening and a lower small opening is formed at the equal circumference above the LED lamp on the inner wall of the lamp shade after one circle of rotation along the parabolic path. The LED lamp has the advantages that the large-range illuminating angle is approximately 320 degrees, and the utilization rate of light source is high.

Description

The LED light fixture
Technical field
The utility model designs a kind of LED light fixture, and the LED light fixture of the big range of exposures of a kind of about 320 degree particularly is provided.
Background technology
LED light fixture in the market generally comprises the pcb board in lampshade on the crown top of burner, lamp body, the lamp body, the lampshade and places some LED lamps on the pcb board, this LED light fixture illumination angle within the specific limits, range of exposures is big inadequately, greatly about the ranges of exposures of 120 degree.
CN201020159442.8 discloses a kind of LED light fixture, comprise lamp body and be located at lampshade on the lamp body, be provided with pcb board in the lampshade, pcb board is provided with some led light sources, and the led light source top is provided with the reflector that can reflect and reflect the light that this led light source sends.Described light fixture provide a kind of light evenly soft, can not produce the light fixture of dazzle, described LED light fixture can enlarge exiting surface to a certain extent.But LED lamp source greatly reduces light utilization efficiency through repeatedly reflection and refraction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of big ranges of exposures about 320 degree simple in structure, big, the LED light fixture of light high usage are provided.
Technical solution of the present utility model is: described LED light fixture comprises the crown top of burner, with integrated lamp holder of the crown top of burner and lamp shell, be buckled in the lampshade in the lamp shell caulking groove, the top of lamp shell is a platform, which is provided with pcb board, pcb board is provided with several LED lamps, and its special character is: described lampshade inwall is positioned at equal circumference position, LED lamp top with parabolic path big on the aftershaping, the horn-like inner cover of little two openings down that rotates a circle.
Preferably, described lampshade and inner cover are made by transparent optical plastic.
Preferably, described lampshade and inner cover are made by transparent optical glass.
Preferably, be provided with fin in the described lamp shell.
Preferably, be provided with the LED lamp driver in the described lamp shell, in order to control and assurance entire circuit.
Compared with prior art, this LED light fixture has about 320 and spends the advantage of irradiating angle and light source high usage on a large scale.
Description of drawings
Fig. 1 is the structure chart of the utility model LED light fixture.
Fig. 2 is the design sketch of the utility model LED light fixture light.
Fig. 3 is the design sketch of existing LED light fixture light.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 shows the utility model most preferred embodiment, as described in Figure 1, in the present embodiment, described LED light fixture comprises the crown top of burner 1, with integrated lamp holder 2 of the crown top of burner and lamp shell 3, be buckled in the lampshade 5 in the lamp shell caulking groove 4, the top of lamp shell 3 is a platform, which is provided with pcb board 6, pcb board 6 is provided with several LED lamps 7, and described lampshade 5 inwalls are positioned at LED lamp 7 tops with equal circumference position parabolic path big on the aftershaping, the horn-like inner cover 8 of little two openings down that rotates a circle.Described lampshade 4 and inner cover 8 are made by transparent optical plastic or optical glass, are provided with fin 9 in the described lamp shell 3, also are provided with LED lamp driver (not shown) in the described lamp shell 3, are used for control and guarantee entire circuit.
The light range of exposures of general LED light fixture as shown in Figure 3, chief ray A and sidelight line B, described light greatly about 120 the degree ranges of exposures.LED light fixture light range of exposures of the present utility model as shown in Figure 2, the light A of the LED lamp 7 on the described pcb board 6 below inner cover 8 openings passes the direct projection of inner cover mouth and goes out, light does not have weakened, a part of light B direct projection of the LED lamp 7 of inner cover below is gone out on the pcb board 6, another part light C is by inner cover reflection transmission downwards, the light of this part reflection has enlarged the range of exposures of original light fixture greatly, approximately is the range of exposures of 320 degree.Described light fixture has not only improved the utilization rate of light source, and has increased the scope of irradiation.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
