Description

The horizontal omnidirectional light extracting LED

Technical field

The utility model relates to the lighting source field, is specifically related to a kind of LED.

Background technology

LED because have that volume is little, power consumption is low, outstanding advantages such as long service life, high brightness, low in calories, environmental protection; Be to replace the optimal light source of conventional light source, be widely used in many lighting fields such as street lamp, bulkhead lamp capable, Tunnel Lamp, shot-light, fluorescent lamp.

The LED wafer is the core component of LED, and it is rectangular-shaped that outward appearance is, as shown in Figure 1, and LED wafer 1 has rectangular-shaped transparent substrates 11, and a side bottom surface of transparent substrates 11 is provided with luminescent layer 12.During 1 work of LED wafer; Light is sent by luminescent layer 12; Directly penetrate by luminescent layer 12 corresponding to a side bottom surface 120 of luminescent layer 12 and the light of four sides on the LED wafer 1; See through transparent substrates 11 corresponding to the light of a side bottom surface 110 of transparent substrates 11 by luminescent layer 12 on the LED wafer 1 and penetrate, the distribution of its emergent light is as shown in Figure 2, and light is vertically penetrated by six faces of LED wafer respectively; Emergent light corresponding to two bottom surfaces 110,120 of LED wafer is stronger, corresponding to the emergent light of four sides of LED wafer a little less than.

The type of LED is varied, divides by structure to be divided into two kinds of patch-type and plug-in types.

Patch-type LED is an example with the white light paster LED; Like Fig. 1, shown in 3; Its structure comprises LED wafer 1, flat support 2 ' and peripheral packing colloid; LED wafer 1 horizontal is installed on the support 2 ', is connected through gold thread 3 ' between the surface electrode 13 of LED wafer 1 and the both positive and negative polarity pin 21 ' of support 2 ', and the surface coverage of LED wafer 1 has phosphor gel 4 '.During installation, the side bottom surface 110 that LED wafer 1 has a transparent substrates 11 is attached to the installed surface of support 2 ', a side bottom surface 120 installed surface of support 2 ' dorsad with luminescent layer 12 through crystal-bonding adhesive.During work; Luminescent layer 12 is luminous; The light that is directly penetrated by four sides of bottom surface of LED wafer 1 120 and LED wafer 1 is that people expect the work light that obtains; The light that is penetrated by the bottom surface 110 of LED wafer 1 through transparent substrates 11 is then blocked by the installed surface of support 2 ', can not be utilized by people.

The LED of plug-in type is like Fig. 1, shown in 4; Its structure comprises LED wafer 1, support 2 and peripheral packing colloid; Support 2 has anodal pin 21 and negative pole pin 22; One end of negative pole pin 12 is provided with the bowl cup 23 that is used to hold LED wafer 1, and LED wafer 1 places in the bowl cup 23, the both positive and negative polarity pin 21 of the surface electrode of LED wafer 1 and support 2, is connected through gold thread 3 between 22.During installation; The side bottom surface 120 that the side bottom surface 110 that LED wafer 1 has a transparent substrates 11 is attached on the inner bottom surface of bowl cup 23 through crystal-bonding adhesive, have a luminescent layer 12 is the inner bottom surface of bowl cup 23 dorsad; That is, the length direction of the positive and negative electrode pin of the bottom surface of LED wafer 1 and support 2 is perpendicular.During work; Luminescent layer 12 is luminous; The light that is directly penetrated by four sides of bottom surface of LED wafer 1 120 and LED wafer 1 is that people expect the work light that obtains, and sees through the light that transparent substrates 11 penetrates by the bottom surface 110 of LED wafer 1 and is then blocked by bowl cup 23, can not be utilized by people.

The LED of existing this patch-type and plug-in type, after its encapsulation, the light that is penetrated by the bottom surface 110 of LED wafer 1 through transparent substrates 11 can not be utilized; And the light that penetrates by four sides of LED wafer 1 a little less than, like this, its light direction is limited in a direction basically; When LED was used to Lawn lamp, just only towards ground, its range of exposures was very little for light direction; When LED is used to lamp string or other decorative lamps, also be only luminous towards a direction, decorative effect is relatively poor.

In view of this, the inventor furthers investigate prior art, has invented a kind of wider LED of optical range of going out, and this case produces thus.
