Problems solved by technology

However, it can be seen from the figure that since the LED chip 2 is packaged on the same plane, all the emitted light is fixed within a certain angle range after the effect of the reflective surface 6, and the role of the reflective cup cover 4 is limited and cannot be fully effective. Form secondary reflections, so the light source has not yet reached the ideal state in terms of brightness enhancement

Abstract

The invention relates to the LED technical field, which aims at providing a sloping surface LED supporting frame and an LED light source. An LED enclosure surface is arranged on the surface of the sloping surface LED supporting frame of the invention, the enclosure surface is in a sloping surface such as a conical surface, a truncated cone surface, a pyramid surface or a semisphere surface; at least more than one LED enclosure channel can also be laterally arranged on the sloping surface, or LED enclosure holes can be arranged on the surface layer of the sloping surface. The boundedness of the original plane supporting frame in the secondary reflecting respect by adopting the supporting frame and the LED light source of the invention can be broken through, and the light source brightness can be further increased; the LED light source formed through independent circuits respectively controlling all enclosure channels can produce the special effect of different light distances.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a slope LED bracket and an LED light source. Background technique [0002] In recent years, due to the rapid development of LED light-emitting diodes in terms of brightness and other main technical indicators, they have been widely used in landscape lighting, large-screen display and other occasions. However, in the past, high-power LED light sources were packaged with multiple LED chips on a planar support. When encapsulating, first arrange multiple LED chips and place them together on the encapsulation plane of the bracket, and then fill them with a liquid filler processed from materials such as epoxy resin or silicone resin for encapsulation. As shown in Figure 3, a plurality of LED chips 2 are packaged in the encapsulation layer 3 of the support 5 after being arranged, and the function of the encapsulation layer 3 is to homogenize the light emitted by all LEDs; the support 5 it...
