Abstract
The utility model discloses an LED bulb lamp with a light emitting surface structure of a prismatic table shape. The LED bulb lamp comprises a lampshade and a lamp bead base. The lamp bead base is of the prismatic table shape. Lamp beads are installed on all the faces of the lamp bead base. According to the LED bulb lamp, a traditional plane light emitting surface is changed into the prismatic table shape, the lamp beads are installed on all the faces of the lamp bead base of the prismatic table shape, compared with light emitting surface structures of other shapes, the light emitting surface structure of the prismatic table shape is more uniform in light intensity distribution, stronger in light intensity, wider in wavelength range and higher in light emitting efficiency, the lamp bead base is designed into the regular pentagonal prismatic table shape , the included angle between each side face on the lamp bead base and the vertical direction is 30 degrees, the lamp beads on the five side faces are circumferentially evenly distributed around the lamp beads on the upper bottom surface, and light emitting uniformity and intensity are better.
Description
Technical field
The utility model relates to LED lamp technical field, particularly a kind of LED bulb lamp with terrace with edge shape light-emitting area structure.
Background technology
LED bulb lamp is the Novel energy-saving lamp that substitutes conventional incandescent bulb.LED bulb lamp is mainly to consist of the several parts of light source, drive circuit, heat abstractor and lampshade.And light source is to form light-emitting area structure by several LED lamp pearls rationally arranging of light-emitting area.Reasonably light-emitting area structure plays vital effect for high performance LED bulb lamp.Yet the light-emitting area structure of existing LED bulb lamp is generally a plane, a plurality of LED lamp pearls are with certain formal distribution in luminous flat, and this light-emitting area structure, by optimizing, is not not best ray structure.Therefore, current LED bulb lamp is not high enough, the non-uniform light of luminosity why, and irrational light-emitting area structure is one of the main reasons.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides reasonable in design, luminous evenly, the high a kind of LED bulb lamp with terrace with edge shape light-emitting area structure of brightness.
The utility model solves the technical scheme that its technical problem adopts:
A LED bulb lamp for terrace with edge shape light-emitting area structure, comprises lampshade and lamp bulb seat, and described lamp bulb seat is terrace with edge shape, and each face of lamp bulb seat is all provided with lamp pearl.
As the improvement of technique scheme, described lamp bulb seat is positioned at the center of lampshade.
Further, described lampshade is in the shape of a hemispheroid.
Further, each face of described lamp bulb seat is all provided with the lamp pearl of equal number.
Further, described lamp bulb seat is five terrace with edge shapes.
Further, the upper bottom surface of described lamp bulb seat is regular pentagon, and the angle of each side and vertical direction is 25 ° ~ 35 °.
Further, each side of described lamp bulb seat and the angle of vertical direction are 30 °.
Further, each face of described lamp bulb seat is all provided with a lamp pearl, and the lamp pearl of five sides is circumferentially uniform around the lamp pearl of upper bottom surface.
The beneficial effects of the utility model are: the utility model is by changing traditional flat luminous face into terrace with edge shape, on each face of the lamp bulb seat of terrace with edge shape, lamp pearl is installed, compare with the light-emitting area structure of other shapes, the light distribution of this structure more evenly, light intensity is larger, wave-length coverage is wider, luminous efficiency is higher, especially lamp bulb seat is designed to positive five terrace with edge shapes, each side on it and the angle of vertical direction are 30 °, and the lamp pearl of five sides is circumferential when uniform around the lamp pearl of upper bottom surface, and its uniformity of luminance and intensity are better.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is iso-candela plot distribution map of the present utility model;
Fig. 3 is irradiation level figure of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of LED bulb lamp with terrace with edge shape light-emitting area structure of the present utility model, comprises lampshade 1 and lamp bulb seat 2, and described lamp bulb seat 2 is terrace with edge shape, and each face of lamp bulb seat 2 is all provided with lamp pearl 3; Preferably, described lampshade 1 is in the shape of a hemispheroid, economy attractive in appearance, and can make illumination patterns even, reduce ghost image and dark space; Further, in order to make light distribution more even, described lamp bulb seat 2 is positioned at the center of lampshade 1; Each face of described lamp bulb seat 2 is all provided with the lamp pearl 3 of equal number, and lamp pearl 3 quantity can be determined according to actual conditions.
In this specific embodiment, described lamp bulb seat 2 is five terrace with edge shapes; The upper bottom surface of described lamp bulb seat 2 is regular pentagon, and preferably, the angle of each side and vertical direction is 25 ° ~ 35 °, more preferably 30 °; It is circumferentially uniform around the lamp pearl 3 of upper bottom surface that each face of described lamp bulb seat 2 is all provided with the lamp pearl 3 of 3, five sides of a lamp pearl.Said structure is significantly improved the uniformity of luminous efficiency of the present utility model and light distribution.
Fig. 2 shows iso-candela plot distribution Figure 10 of the present utility model, Fig. 3 shows irradiation level Figure 20 of the present utility model, and as can be seen from Figure 2, distribution map of the present utility model is a peach-shaped, effect for LED bulb lamp at room lighting, this is standard extremely; As can be seen from Figure 3, the utlity model has illumination very uniformly.Through analogue simulation checking, to compare with the light-emitting area structure of other shapes, light distribution of the present utility model is more evenly, light intensity is larger, wave-length coverage is wider, luminous efficiency is higher.
Certainly, the utility model, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should be within its protection domain.
