Abstract

The utility model discloses a wide angle light-emitting diode (LED) lamp. The wide angle LED lamp comprises a lamp holder, a radiator and a bulb shell which are connected in sequence. A lens column is arranged in the center of the end face of the radiator inside the bulb shell, and first LED light sources which are lower than the lens column and face towards the lens column are evenly installed around the lens column. The bottom end of the lens column recesses towards the lens column to form a first space, at least one second LED light source is installed on the end face of the radiator corresponding to the space, and the second LED light source faces towards the top end of the lens column. According to the wide angle LED lamp, light emitted out from the first LED light sources is refracted or reflected by the lens column and is emitted out of the bulb shell evenly, part of light can deviate towards one side of the lamp holder under the condition of refraction so as to enlarge the lighting angle, light emitted out from the second LED light source is also refracted or reflected by the lens column and is emitted out of the bulb shell, part of light can deviate towards one side of the lamp holder under the condition of refraction so as to enlarge the lighting angle, and the wide angle LED lamp guarantees a large enough irradiating angle under the condition that luminance is ensured.

Description

Extensive angle LED lamp

Technical field

The utility model relates to lighting field, relates in particular to a kind of LED lamp of wide-angle illumination.

Background technology

At present, for the wide-angle that realizes the LED lamp luminous, industry is generally established a polyhedron in cell-shell, light source is arranged on the surface of these polyhedron different angles (as plane and vertical plane), though this method can reach bigger lighting angle, but still have following defective: the light emission direction of this LED lamp is for forward with towards side, therefore have only less light to shine the lamp holder direction of light fixture, make whole lamp can not as traditional incandescent light bulb to all directions uniformly light-emitting, be difficult to realize that the wide-angle more than 300 degree is luminous.

The utility model content

The utility model aims to provide a kind ofly can realize that the illumination of led light source is mapped to the LED lamp of the wide-angle uniformly light-emitting of lamp holder direction.

To achieve these goals, the a solution that the utility model proposes is: a kind of extensive angle LED lamp, comprise the lamp holder, radiator and the cell-shell that connect successively, be provided with lens post in the end face of radiator in the heart, around lens post, be equipped with uniformly and be lower than and towards a plurality of first led light sources of lens post; The bottom of described lens post forms a space to the lens post sunken inside, and at least one second led light source is installed on the end face of the described radiator of this space correspondence, and this second led light source is towards the top of lens post.

Wherein, described space is columned cavity, and the sidewall of this columned cavity is male and fomale(M﹠F), or the sidewall of columned cavity is provided with a plurality of outstanding polyhedrons.

Wherein, the top end face of described columned cavity is to the recessed cambered surface of inside cavity.

Wherein, described lens post is that the trapezoidal round platform narrow through radiator one end, that the other end is wide is leaned in the longitudinal section, and the described first led light source vertical plane is to round table-like lens post side surface.

The beneficial effects of the utility model are: be different from existing LED lamp, establish a polyhedron in the cell-shell, light source is arranged on the surface of these polyhedron different angles, extensive angle LED lamp of the present utility model, in the end face of radiator, be provided with lens post in the heart, around lens post, be provided with first led light source towards lens post then uniformly, the light that several first led light sources send is through the refraction of lens post or being transmitted into outside the cell-shell of the reflection uniform wide-angle in back, some light can a side of deflection lamp holder make light angle become big under the situation of refraction, and second led light source is equally through being transmitted into outside the cell-shell uniformly after the refraction of lens post or the reflection, some light can a side of deflection lamp holder make light angle become big under the situation of reflection, makes extensive angle LED lamp of the present utility model guarantee also that under the situation that brightness guarantees the angle of irradiation is enough big.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, a kind of extensive angle LED lamp of present embodiment, comprise successively the lamp holder 1, radiator 2 and the cell-shell 3 that connect, in the end face of radiator 2, be provided with lens post 4 in the heart, around lens post 4, be equipped with uniformly and be lower than and towards a plurality of first led light sources 5 of lens post 4; The bottom of described lens post 4 forms a space to lens post 4 sunken insides, and at least one second led light source 6 is installed on the end face of the described radiator 2 of this space correspondence, and this second led light source 6 is towards the top of lens post 4.

Extensive angle LED lamp of the present utility model, in the end face of radiator 2, be provided with lens post 4 in the heart, around lens post 4, be provided with first led light source 5 towards lens post then uniformly, the light that several first led light sources 5 send is through the refraction of lens post 4 or being transmitted into outside the cell-shell 3 of the reflection uniform wide-angle in back, some light can a side of deflection lamp holder 1 make light angle become big under the situation of refraction, and be transmitted into uniformly outside the cell-shell 3 after the refraction of second led light source, 6 same process lens post or the reflection, some light can a side of deflection lamp holder 1 make light angle become big under the situation of reflection, makes extensive angle LED lamp of the present utility model guarantee also that under the situation that brightness guarantees the angle of irradiation is enough big.

In the present embodiment, described space is columned cavity, the sidewall of this columned cavity is male and fomale(M﹠F), or the sidewall of columned cavity is provided with a plurality of outstanding polyhedrons, after light that first, second led light source sends is by male and fomale(M﹠F) or polyhedron, the LED light fixture is produced dazzle beautiful colorful visual effect, be similar to the visual effect of quartzy LED lamp.

In the present embodiment, the top end face of described columned cavity is to the recessed cambered surface 7 of inside cavity, makes the corresponding lens post in top in described space partly form convex lens like this, makes it have the effect of optically focused.

In the present embodiment, described lens post 4 is leaned on the trapezoidal round platform narrow through radiator one end, that the other end is wide for the longitudinal section, described first led light source, 5 vertical planes are to round table-like lens post side surface, the light that makes lens post 4 first led light source, 5 emissions on every side like this, not only Zhe She light has the direction of part deflection lamp holder 1, the direction of the light deflection lamp holder 1 that also has part of the light of part reflection makes its irradiating angle become big.
