Abstract

The utility model provides a ceramic layer plated base for a light-emitting diode (LED) light source multiple-cup module. The base comprises a substrate and a plurality of reflection cups arranged on the substrate, the lighting faces for installing LEDs are arranged on the reflection cups and plated with ceramic layers, the white degree of the ceramic layers>=70, preferably>=85, and optimally>=88. The substrate and the reflection cups are formed by integral molding, or the reflection cups are fixed on the substrate in bonding mode, and the substrate is further provided with a small groove extending into the lateral walls of the reflection cups and used for installing circuit boards. The ceramic layer plated base for the LED light source multiple-cup module can reduce manufacture procedures of a reflection layer arranged on a traditional LED metal base, simplify production process and greatly save production cost, thereby being favorable for mass industrial production and simultaneously being capable of adopting a prefabricated method to directly produce the base. Due to the fact that the high white degree ceramic layers are plated on the reflection cups of the base, the light-taking efficiency of an LED chip can be greatly improved, thereby being capable of reducing the consumption that luminous energy is converted into heat energy, the radiation performance of the base can also be greatly improved, LED lamps formed by the base have good safety performance, cannot conduct electricity, are not easy to break and have greatly improved service life.

Description

Many glasss of modules of led light source are with plating ceramic layer base

Technical field

The utility model relates to a kind of lighting apparatus, relates in particular to a kind of LED lamp.

Background technology

LED is a kind of low voltage light sources, because its power saving, life-span are long, has been widely used in various lighting devices at present; If traditional LED bulb lamp all adopts metal material as the LED base plate for packaging, because the whiteness of metal substrate own is lower, therefore the not treated encapsulation base plate of directly making the LED lamp; Its reflector efficiency is not high; Particularly in great power LED was used, because its caloric value is bigger, life of product was lower; Therefore the light-emitting area on the existing metal substrate all can be handled earlier, as improving its whiteness as the reflector layer of reflector layer or pressing one deck white at its surface brush one deck white paint, but this way; At first its technology is complicated; Production cost is higher, simultaneously, because after having increased one deck reflector layer; Traditional its heat dispersion of led light source module encapsulation construction reduces greatly, can't solve the heat dissipation problem of high-power LED light source module more.

Summary of the invention

The technical problem that the utility model will solve is to provide a kind of and can either saves production cost, can keep many glasss of modules usefulness of the led light source plating ceramic layer base of heat dispersion preferably again.

The technical scheme that the utility model adopts is: the light-emitting area that is used to install LED on the said reflector is coated with the ceramic layer of a high whiteness.

Said substrate and reflector are to adopt one-body molded processing, or reflector is bonded and fixed on the substrate.

The whiteness of said ceramic layer >=70, be more preferred from >=85, the best is >=88.

The sidewall of said reflector also is provided with opening, also is concaved with a circuit board slot on the said base, and this circuit board slot extends to respectively in the opening of reflector sidewall, and circuit board slot below also is provided with a through hole.

The bottom of said circuit board slot is lower than the bottom of reflector.

Said base and reflector are circle.

Said reflector is 6, and said circuit board slot is " king " font.

Compared with prior art, the utlity model has following advantage: since said substrate and reflector be employing metal material is one-body molded processes, or after being bonded and fixed at reflector on the substrate; Plating high whiteness ceramic layer again handles; The reflector layer production process that can reduce traditional LED to adopt metab and need to increase had both been simplified production technology, can save production cost greatly; Help large batch of suitability for industrialized production, can adopt prefabricated mode Direct Production base simultaneously; The utility model people finds through long-term a large amount of experiment in addition, the whiteness of its base reflective surface is increased to >=70, he can promote well and get optical efficiency, and heat dispersion is excellent; Its whiteness is >=88 best results if lifting is better for >=85 effects if promote; Because after being coated with high whiteness ceramic layer on the reflector of base; The getting optical efficiency and will promote greatly of led chip; Therefore can significantly reduce luminous energy and be converted into heat energy loss, so its heat dispersion also will improve greatly, good with its its security performance of LED lamp of processing; Non-conductive, also improve greatly non-friable service life.

Description of drawings

Combine embodiment that the utility model is further described with reference to the accompanying drawings.

Fig. 1 is the overall structure sketch mapes of many glasss of modules of the utility model led light source with plating ceramic layer base.

Fig. 2 is the B-B generalized section of Fig. 1.

The specific embodiment

Come the utility model is carried out detailed explanation below in conjunction with specific embodiment.

Many glasss of modules of a kind of led light source are with plating ceramic layer base; Said base comprises substrate 1 and is arranged on 6 reflectors 2 on the substrate; Also be provided with opening 21 on the sidewall 22 of said reflector 2, also be concaved with a circuit board slot 3 on the said base, said circuit board slot 3 is " king " font; This circuit board slot 3 extends to respectively in the opening 21 of reflector 2 sidewalls; Circuit board slot 3 belows also are provided with a through hole 31, and the light-emitting area that is used to install led chip on the said reflector 2 is coated with a ceramic layer 23, the whiteness of said ceramic layer 23 >=70; Be more preferred from >=85; The best is >=88.

Said substrate 1 and reflector 2 are to adopt that metal material is one-body molded to be processed, or reflector 2 is bonded and fixed on the substrate 1.The bottom of said circuit board slot 3 is lower than the bottom of reflector 2, is convenient to after wiring board is installed equally with the reflector bottom, and base described in the present embodiment and reflector are circle.

Therefore traditional general whiteness of LED metab needs light-emitting area above that to increase the reflector layer production process in actual production all less than 70, but do like this heat dispersion of LED base is reduced greatly, and increase production process, has also increased production cost.The utility model is employed in the way that the light-emitting area of reflector is plated the ceramic layer of a high whiteness; Can burn out the concrete shape that has reflector, opening, circuit board slot and through hole that needs according to the prefabricated base that processes the size of needs of production needs, both can satisfy the requirement of whiteness >=70; Can improve heat dispersion again; Both can simplify production technology, can also save a large amount of production costs, help large batch of suitability for industrialized production; Simultaneously can adopt prefabricated mode Direct Production base, production efficiency will improve greatly.

In the foregoing description, the shape of said base also is not limited to circle, can do shapes such as squarely or strip, still can reach aforesaid utility model purpose.
