Because single led lamp pearl power is little, generally a plurality of LED lamp pearls are combined as a luminescence unit with series connection or mode in parallel as lighting bulb, but because LED lamp pearl irradiating angle is little, so be difficult to penetrate from lampshade uniformly, cause the uneven illumination weighing apparatus, blackening appears, influenced the integral illumination effect, because such cause, the LED lamp generally also can only be applicable to globular bulb, can't be applicable to the strip bulb.

The utility model content

In order to overcome not good, the poor for applicability deficiency of LED lamp illuminating effect of prior art, the utility model provides a kind of LED ray structure of wide-angle high brightness.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of LED ray structure of wide-angle high brightness comprises lamp socket, lampshade and LED wick.

Lamp socket, inside is provided with power module; Lampshade, be installed on the lamp socket, this lampshade is: opening is connected in series from beginning to end towards the multi-section circular arc of same longitudinal central axis and encloses a flap occluding contour that is on the transverse plane, this occluding contour extends along this axis, its upper end is smoothly drawn into a hemispherical top in, the lower end is drawn in and is formed an installation portion that is connected with lamp socket, and inner pumping forms a printing opacity housing; The LED wick comprises the wick substrate, and the lower end of wick substrate is fixed on the lamp socket, and the upper end is stretched in the lampshade and is provided with a kink, and a wick substrate side and a kink side up thereof outwardly is provided with LED paster lamp pearl.

In order to improve illuminating effect, expand illumination zone, increase the brightness of light source, a plurality of LED wicks are fixedly arranged on the described lamp socket, the LED wick evenly is arranged in around the axis, and its kink bends towards central axis direction.

In order to make light more even, reduce the light dark space, being angle between described kink and the wick base main body is 150 degree.

In order to improve radiating effect, prevent that internal circuit is overheated, described lamp socket arranged outside has the vertical radiating fin of annular distribution.The heat that sends directly carries out heat exchange by radiating fin and the external world, radiating fin strengthened and outside air between contact area, thereby accelerate the cooling process.

For the ease of installation and removal, and keep good sealing property, by being threaded, the junction is provided with fluid sealant between described lampshade and the lamp socket.

The beneficial effects of the utility model are: use the LED wick with kink luminous, and cooperate the lampshade structure of special shape, illumination brightness is big, and radiation scope is wide; Be conducive to bright dipping, make illumination even, can not produce blackening; Not only can be applied to globular bulb, can also make the strip bulb, the scope of application is wide, can wholely substitute existing electricity-saving lamp; Simple in structure, be easy to processing and assembling.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is structural representation of the present utility model;

The specific embodiment

Referring to figs. 1 through Fig. 3, the LED ray structure of a kind of wide-angle high brightness of the present utility model comprises lamp socket 1, lampshade 3 and LED wick 2.

Lamp socket 1, inside is provided with power module; Lampshade 3, be installed on the lamp socket 1, this lampshade 3 is: opening is connected in series from beginning to end towards the multi-section circular arc of same longitudinal central axis and encloses a flap occluding contour that is on the transverse plane, this occluding contour extends along this axis, its upper end is smoothly drawn into a hemispherical top in, the lower end is drawn in and is formed an installation portion that is connected with lamp socket 1, and inner pumping forms a printing opacity housing; LED wick 2 comprises wick substrate 21, and the lower end of wick substrate 21 is fixed on the lamp socket 1, and the upper end is stretched in the lampshade 3 and is provided with a kink 23, and wick substrate 21 side and kink 23 side up thereof outwardly is provided with LED paster lamp pearl 22.

In this specific embodiment, the multi-section circular arc of enclosing occluding contour is identical circular arc, makes the outward appearance symmetry of lampshade 3, and is more regular.Certainly, in order to realize asymmetric lamp body moulding, circular arc can be arranged to the circular arc that size, curvature differ from one another.
