Abstract

The utility model discloses a cambered LED (Light-Emitting Diode) lamp, comprising a base and an encapsulation resin, wherein a cambered epitaxial wafer is mounted on the base; and an LED chip grows on the cambered epitaxial wafer. Compared with the prior art, the half-value angle of the convex LED lamp provided by the utility model can reach 135 degrees, while the half-value angle of the concave LED lamp can reach 90 degrees; besides, the luminous intensity is free of negative influence of a scattering diluent and a lens and the previous luminous intensity of the LED lamp is remained.

Description

A kind of arc LED lamp

Technical field

The utility model relates to a kind of LED lamp, is specifically related to a kind of arc LED lamp.

Background technology

Excellent properties such as that the LED light fixture has is energy-efficient, long service life are widely used in various fields, and the lighting angle of LED is generally-90 °～+ 90 °, but in order to satisfy various functions, need demands of different be arranged to the wide lighting angle of LED.The brightness of existing LED lamp has positive connection with its luminous intensity, and the light angle of LED lamp is more little, and its brightness is high more; Correspondingly, angle is big more, and brightness is low more.For example, scatter-type LED lamp, the visual angle is bigger, and half-value angle is 45 °～90 ° or bigger, but it uses more a large amount of scattering diluents, causes luminous intensity to reduce greatly; Or change the LED lighting angle in the method that led chip adds lens, because of having added the light output that lens can reduce LED, reduced the luminous intensity of LED lamp equally.

The utility model content

Given this, the purpose of the utility model is to provide a kind of change light half-value angle, and the high arc LED lamp of luminous intensity.

For solving the problems of the technologies described above, the utility model changes the luminous direction of LED lamp through the shape that changes epitaxial wafer, to reach the purpose of optically focused or floodlight.The utility model provides a kind of arc LED lamp, comprises pedestal and potting resin, and the arc epitaxial wafer is installed on pedestal, on the arc epitaxial wafer, generates led chip.

Said arc epitaxial wafer is outer convex or indent arc.

The radian of said outer convex is π/180～pi/2.

Preferably, said radian is π/18～π/6.

The radian of said indent arc is π/180～π/4.

Compared with prior art, the half-value angle of the utility model male type LED lamp can reach 135 °, and the half-value angle of inner concave shape LED lamp can reach 90 °, and luminous intensity does not receive the negatively influencing of scattering diluent and lens, has kept the original luminous intensity of LED lamp.
