Problems solved by technology

[0005] However, the current light-emitting diodes (which are constructed as Figure 5A and 5B Shown) under high operating current, its brightness will not increase proportionally with the increase of operating current, and its service life will be affected
like Figure 5B The traditional light-emitting diode shown in the figure, the base substrate is usually made of PC board or alumina ceramics, etc., and the thermal conductivity of these base substrate materials is not good
Due to poor heat dissipation of traditional light-emitting diodes, high operating current will significantly reduce its service life
like Figure 5A The traditional light-emitting diode shown in the figure, its bracket is made of Kovar alloy or copper metal, etc., but the bracket is too thin and does not significantly help its heat dissipation

Embodiment Construction

[0014] In order to make those skilled in the art understand the purpose, characteristics and effects of the present invention, the present invention will be described in detail by the following specific embodiments and in conjunction with the accompanying drawings:

[0015] figure 1 It is a sectional view of a preferred embodiment of the light emitting diode of the present invention. The light emitting diode includes a base substrate 11 , a flip-chip light emitting diode die 16 , a cover substrate 17 and a convex lens 18 formed of transparent resin or epoxy resin. Wherein, the base substrate 11 has an insulating region 19 , which is used to separate the base substrate 11 into two parts that are not connected to each other.

[0016] The base substrate 11 is covered by a plurality of metal layers above and below, which are respectively marked as the metal layer 12 , the metal layer 13 , the metal layer 14 , and the metal layer 15 . Among them, the metal layer 12 and the metal...

Abstract

The high-brightness light-emittnig bipolar body includes one seat plate, one compound crystal light-emitting bipolar body crystallite with transparent base plate and one covering plate. The covering plate has one central hole with inclined side wall and the light-emitting bipolar body crystallite is held inside the hole. The seat plate is divided into two parts by one middle insulating area and the two parts are connected separately to two electrodes of the light-emitting bipolar body crystallite. The seat plate is made of matter with high heat conductivity and high electric conductivity for conducting great current and dissipating heat. The central hole is filled and the light-emitting bipolar body crystallite is packed with transparent resin or epoxy resin. The present invention can emit high-strength light.

Description

technical field [0001] The invention relates to a light-emitting diode, in particular to a high-brightness light-emitting diode with flip-chip light-emitting diode grains. Background technique [0002] Due to low power consumption, small size, and long service life, light-emitting diodes are currently widely used in home appliance audio indicator lights, mobile phone backlights, light-emitting diode signage, and third brake lights for cars. In recent years, due to the successful development of new light-emitting diode materials such as aluminum gallium indium phosphide (AlGaInP) and indium gallium aluminum nitride (AlGaInN), the brightness of light-emitting diodes can be further improved, so it can be used in many In application, light-emitting diodes are used to replace traditional incandescent bulbs. At present, visible light-emitting diodes are used in applications such as traffic lights, automobile tail lights, and direction lights. In the future, with the improvement ...
