Description

A two-stage bendable LED packaging bracket

technical field

The invention relates to an LED packaging bracket for installing LED chips and then packaging fluorescent powder to form an LED lamp, in particular to a LED packaging bracket with a two-stage bendable head.

Background technique

LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, is mainly electron here. But time these two kinds of semiconductors couple together, between them, just form a "P-N junction". When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is with hole recombination, then will send energy with the form of photon, the principle of LED luminescence that Here it is. And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction.

The practicality and commercialization of high-performance LEDs have brought about a new revolution in lighting technology. The pixel light composed of multiple ultra-high-brightness red, blue, and green LEDs can not only emit various colors of light with continuously adjustable wavelengths, but also emit white light with a brightness of tens to one hundred candlepower as a lighting source. For incandescent lamps and LED solid-state lighting lamps with the same luminance, the power consumption of the latter only accounts for 10%-20% of the former.

Most of the white LEDs currently produced are made by coating blue LEDs with a yellowish phosphor coating, which is usually made by grinding cerium-doped yttrium aluminum garnet crystals into powder and mixing them in made from a dense adhesive. When the LED chip emits blue light, part of the blue light will be efficiently converted into a broad-spectrum mainly yellow light by the crystal, because the yellow light will stimulate the red and green light receptors in the naked eye, and then mix the blue light of the LED itself , making it look like white light.

Existing LED lamps are generally installed directly on the mounting board, and the mounting board is generally a sheet structure, including three layers: a heat dissipation layer for heat dissipation, an insulating layer for insulation under the heat dissipation layer, and an insulating layer under the insulating layer. The circuit layer for wiring, in which the heat dissipation layer is generally aluminum foil or aluminum alloy sheet; the circuit layer is generally made of copper foil for circuit layout.

The existing manufacturing process of LED lamps is pressure welding, encapsulation and curing. Pressure welding is to pressure-weld the LED chip to the electrode; LED packaging is to encapsulate the mixture of phosphor powder and epoxy resin on the bonded LED chip; curing is to fully cure the mixture of epoxy resin and phosphor powder.

Most of the existing full-radiation angle LED light bulbs are a combination of multiple LED lamps. The multiple LED lamps are installed on a frame to emit light at various angles, thereby obtaining the effect of a full-radiation angle. The structure and shape of existing LED lamps limit the shape of existing full-radiation angle LED bulbs.

Contents of the invention

In order to overcome the deficiencies of the prior art and provide a new LED lamp for a new type of full-radiation angle LED bulb, the present invention proposes a two-stage bendable LED packaging bracket, including an input end, the input end Form a "convex"-shaped sheet, the input end has an upper through hole between the protruding part of the "convex" and the non-protruding part of the "convex", and the upper through hole is set There is an upper metal sheet matching its shape; there is a lower through hole from the lower part to the lower edge of the non-protruding part of the "convex" shape, and a metal sheet output end matching its shape is provided in the lower through hole; The head LED light cup is formed by injection molding between the protruding part of the "convex" shape and the upper part of the upper metal sheet, and the tail part is formed by injection molding between the lower part of the upper metal sheet and the output end of the lower metal sheet LED light cup; a bendable part is formed between the head LED light cup and the tail LED light cup, so that the head LED light cup can be bent at the bendable part.
