And referring to the drawings, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
Embodiment 1
As shown in Figure 1, 2, 3, the LED of a kind of high light-emitting efficiency wide-angle outgoing uniform light of the present utility model, bag
Include：Chip 3, packaging plastic 4；Wherein, the packaging plastic 4 is arranged on the outer layer of chip 3；The chip 3 includes what is set gradually
Sapphire Substrate 31, n-contact layer 32, luminescent layer 33, P type contact layer 34, reflecting layer 35；The chip 3 also includes：With it is described
The n-type electrode 36 of the connection of n-contact layer 32, the P-type electrode 37 being connected with the reflecting layer 35；The n-type electrode 36 and the P
Type electrode 37 is fixedly connected on the bracket 38 by conducting resinl 39；The sapphire pad etching is multiple projections being set up in parallel
Shape.Wherein, the etching of Sapphire Substrate 31 is the device being made up of the hemispherical shape of multiple arranged in parallel.The encapsulation
The extension of glue 4 is provided with reflector layer 5, wherein, the reflector layer 5 is non-transparent conductive layer, sets reflector layer 5, reduces because of light
Deterioration cause the less phenomenon of light efficiency.
Specifically, after luminescent layer 33 emits beam, a part of light is directly over n-contact layer 32 and Sapphire Substrate 31
Reach Sapphire Substrate 31 and the contact surface of packaging plastic 4.And then another part light reach reflecting layer by P type contact layer 34
35, then reflected layer 35 sequentially passes through P type contact layer 34, luminescent layer 33, n-contact layer 32 and Sapphire Substrate again after reflecting
31 reach Sapphire Substrate 31 and the contact surface of packaging plastic 4.The present embodiment is by the way that sapphire pad etching is set side by side to be multiple
The convex shape put.So set and change light by sapphire pad and the incident angle of the contact surface of packaging plastic 4, in addition,
In the prior art, sapphire pad surface be level, such light by when, be perpendicular to sapphire pad surfaces outgoing
, sapphire pad is set to multiple convex shapes being set up in parallel, the so refraction effect due to light so that light can be from
Outgoing from all directions.
