Abstract

The utility model discloses a wide-angle LED packaging device, which comprises a copper column (5), a chip (1), a silica gel lens (4) and a support (6), wherein the copper column (5) is fixed in the middle of the support (6), the silica gel lens (4) is connected with the upper surface of the support (6) in a sealed mode to form a sealed cavity, fluorescent powder (2) is filled in the sealed cavity between the silica gel lens (4) and the copper column (5), the chip (1) is positioned in a hollow cavity, the copper column (5) is provided with a boss (3), and the chip (1) is fixed on the boss (3) of the copper column (5). The LED packaging device with a wide luminous angle can be acquired and the luminous angle can reach 165 degrees to the maximum.

Description

A kind of large-angle LED packaging
Technical field
The utility model relates to a kind of LED single-chip packaging.
Background technology
At present, the lighting angle of existing on the market lambert's type LED packaging all between 40 ° ~ 120 °, the only product of suitable optically focused such as flashlight, shot-light, Down lamp, flood light etc. in the application of light fixture.But in the uniform occasion of needs illumination, the great power LED device of the common angle of this class just can't satisfy the needs that light fixture is produced, the most typical light fixture is exactly a Panel light, Panel light is very high to the photochromic inhomogeneity requirement of LED, but existing LED packaging is difficult to satisfy people's requirement for a short time because of lighting angle, therefore, exploitation and composition goes out more that the LED packaging of wide-angle has bigger value.
The utility model content
The purpose of this utility model is exactly to solve the little problem of existing LED packaging lighting angle, and a kind of large-angle LED single-chip packaging is provided.
The technical solution adopted in the utility model is: a kind of large-angle LED packaging, it comprises the copper post, is fixed on chip, silica-gel lens and rack body on the copper post, the copper post is fixed in the central authorities of rack body, the silica-gel lens of segment shape and the rack body upper surface formation annular seal space that is tightly connected, be filled with fluorescent material in the annular seal space between silica-gel lens and the copper post, chip is positioned at cavity, it is characterized in that described copper post is provided with boss, and chip is fixed on the boss of copper post.
Adopt technique scheme, because chip is fixed on the boss of copper post, the light that chip sends to the side does not have any blocking, the angle of chip light emitting has obtained increase, lighting angle after the silica-gel lens refraction has obtained increase too again, therefore can increase lighting angle, the lighting angle maximum can reach 165 °.
For further increasing lighting angle of the present utility model, the segment exterior arc surface of described silica-gel lens is less than the hemisphere arc surface.To produce bigger refraction angle like this, lighting angle is further strengthened.
The utility model beneficial effect is: because chip of the present utility model is fixed on the boss, the lighting angle of chip is increased, through the further reinforcement of silica-gel lens, make it possible to obtain the LED single-chip packaging of wide-angle.
