Problems solved by technology

[0003] The shape of the light field produced by the traditional LED packaging structure is mostly circular, but in some lighting occasions, a long light field is often required, such as road lighting. If the light field of the street lamp is circular, part of the light will be Illuminating outside the range of the road will not only cause waste of resources but also may cause wrong traffic guidance. In this case, it is better to require the lighting area formed by the street lamp to be roughly elongated, with a larger lighting length in the direction along the road, and Has a small lighting length in the direction perpendicular to the road
However, for ordinary strip lighting devices, the light will scatter along the direction parallel to the electrodes of the LEDs, resulting in insufficient concentration

Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] see Figure 1 to Figure 6 A light emitting diode packaging structure 100 provided in an embodiment of the present invention includes a base 10, at least one light emitting diode chip 20 disposed in the base 10, and a package disposed in the base 10 and covering the light emitting diode chip 20 Layer 30.

[0044] see next figure 2 , the base 10 includes an insulating seat 11 and a first electrode structure 12 and a second electrode structure 13 disposed on the insulating seat 11 . The insulating base 11 is a cuboid structure, its long side extends along the first direction X, and its short side extends along the second direction Y. The insulating base 11 includes a rectangular base 111 , a first side wall 112 extending vertically upward from two long sides of the base 111 , and a second side wall 114 vertically extending upward from two short sides ...

Abstract

An LED packaging structure comprises a pedestal and at least one LED chip, the length of the pedestal along a first direction is greater than that of the pedestal along a second direction which is vertical to the first direction, an accommodation cavity is formed in the pedestal, the accommodation cavity penetrates the top and two ends along the first direction of the pedestal, the accommodation cavity includes a positive opening in the top of the pedestal as well as lateral openings in the two ends along the first direction of the pedestal respectively, and light emitted by the LED chip is emitted out via the positive and lateral openings of the pedestal.

Description

technical field [0001] The invention relates to a light emitting diode packaging structure. Background technique [0002] Compared with traditional light sources, light emitting diodes (Light Emitting Diode, LED) have the advantages of light weight, small size, low pollution, long life, etc. As a new type of light source, they have been more and more widely used. [0003] The shape of the light field produced by the traditional LED packaging structure is mostly circular, but in some lighting occasions, a long light field is often required, such as road lighting. If the light field of the street lamp is circular, part of the light will be Illuminating outside the range of the road will not only cause waste of resources but also may cause wrong traffic guidance. In this case, it is better to require the lighting area formed by the street lamp to be roughly elongated, with a larger lighting length in the direction along the road, and Has a smaller lighting length in the direct...
