Description

A kind of luminous uniform LED

Technical field

This utility model relates to technical field of semiconductor illumination, particularly to a kind of luminous uniform LED.

Background technology

LED is high because of its light source light-emitting efficiency, and service life is long, security reliability is high and the advantage of energy-conserving and environment-protective and obtain wide General application, however LED in the light intensity of its dead ahead outgoing more than the light intensity of surrounding, or cause non-uniform light.

Utility model content

The purpose of this utility model is to overcome the defect of LED non-uniform light in above-mentioned prior art, it is provided that a kind of Luminous uniform LED.

In order to realize the purpose of this utility model, be the technical scheme is that

A kind of luminous uniform LED, the light source assembly including heat sink section bar and being arranged on heat sink section bar and diffuser, Described light source assembly is positioned at inside diffuser, and described light source assembly includes that matrix and chip, described diffuser are semicircle saturating Light shield, the thickness of described diffuser is the most thinning to two ends from center, the inner surface of described diffuser be shaped as bending Wave.

Further, the shape of cross section of the inner surface of diffuser be bending sine curve, sinusoidal amplitude from The center of diffuser is gradually increased to two ends.

Further, in cross-sectional direction, the radius that the sinusoidal amplitude of diffuser inward flange point is put with this It is inversely proportional to the angle of centrage.

Further, in cross-sectional direction, the sinusoidal amplitude of diffuser inward flange point is diffuser of point for this 0.001～0.002 times of the ratio of the radius that external diameter is put with this and the angle of centrage.

Preferably, in cross-sectional direction, outside the diffuser that the sinusoidal amplitude of diffuser inward flange point is put for this 0.0015 times of the ratio of the radius that footpath is put with this and the angle of centrage.

Further, described LED also includes lamp holder and power supply.

The beneficial effects of the utility model are:

(1) use thick middle, the diffuser that both sides are thin, the light intensity of both sides illumination can be strengthened；

(2) the sinusoidal amplitude in the middle of is relatively big, and this version can make the folding of the light of diffuser mid portion Firing angle degree and refraction number of times are more than refraction angle and the refraction number of times of the light at diffuser two ends, make middle and both sides illumination strong Degree homogenizes.

Accompanying drawing explanation

With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a kind of luminous uniform LED lamp structure schematic diagram of the present utility model；

Fig. 2 is the diffuser schematic cross-section of the uniform LED of a kind of luminescence of the present utility model.

Wherein, 1, heat sink section bar, 2, light source assembly, 3, diffuser.

Detailed description of the invention

Such as Fig. 1-2, a kind of luminous uniform LED, including heat sink section bar 1 and the light sources being arranged on heat sink section bar 1 Part 2 and diffuser 3, it is internal that light source assembly 2 is positioned at diffuser 3, and light source assembly 2 includes matrix and chip, and LED also includes lamp holder And power supply, diffuser 3 is semicircle diffuser, and the thickness of diffuser 3 is the most thinning to two ends from center, the interior table of diffuser 3 The wave being shaped as bending in face, in the present embodiment, the shape of cross section of the inner surface of diffuser 3 is the sinusoidal bent of bending Line, sinusoidal amplitude is gradually increased to two ends from the center of diffuser 3.

Such as Fig. 2, in cross-sectional direction, the radius of the sinusoidal amplitude of diffuser 3 inward flange point and this point with The angle a of centrage is inversely proportional to.In cross-sectional direction, it is saturating that the sinusoidal amplitude of diffuser 3 inward flange point is put for this 0.001～0.002 times of the ratio of the radius that light shield 3 external diameter is put with this and the angle of centrage, wherein, radius of this point with The unit of the angle a of centrage is degree.Preferably, in cross-sectional direction, the sinusoidal amplitude of diffuser 3 inward flange point 0.0015 times of the ratio of the radius that diffuser 3 external diameter put for this is put with this and the angle a of centrage.

Should be appreciated that specific embodiment described above is only used for explaining this utility model, be not used to limit this reality With novel.The obvious change extended out by spirit of the present utility model or variation are still in protection of the present utility model Among scope.
