Abstract

The utility model provides a ceramic layer-plating base for an LED (light-emitting diode) light source single-cup module, which comprises a base plate and a light reflecting cup arranged on the base plate, and is characterized in that a light-emitting surface which is arranged on the light reflecting cup and is used for installing an LED is plated with a ceramic layer; and for the ceramic layer, the whiteness is more than or equal to 70, the better whiteness is more than or equal to 85, and the best whiteness is more than or equal to 88. The base plate and the light reflecting cup are made in an integral molding way, or the light reflecting cup is bonded and fixed on the base plate; and the base plate is also provided with a small groove which extends into the side wall of the light reflecting cup and is used for installing a circuit board. The ceramic layer-plating base reduces the working procedures for manufacturing a light reflecting layer on a traditional LED metal base, thus not only simplifying the production technique, but also greatly saving the production cost and being beneficial to large-scale industrialized production; meanwhile, the base can be directly produced in a prefabricated way, and the light extraction efficiency of an LED chip is greatly improved after the whiteness of the light-emitting surface of the light reflecting cup of the base is improved, so that the loss during the transformation from luminous energy to heat energy can be greatly reduced, and the heat dispersion performance is also greatly improved; furthermore, an LED lamp made of the ceramic layer-plating base is good in safety performance, non-conducting and unbreakable, so that the service life of the lamp is also greatly prolonged.

Description

Single glass of module of led light source is 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 single glass of module usefulness of the led light source plating ceramic layer base of heat dispersion preferably again.

The technical scheme that the utility model adopts is: single glass of module of a kind of led light source is with plating ceramic layer base; Said base comprises substrate and is arranged on the reflector on the substrate, it is characterized in that: 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, and perhaps reflector is bonded and fixed on the substrate.

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

Also be provided with the sulculus that is used to install wiring board on the said substrate.

Said sulculus is located at the outside of reflector, and extends into the reflector sidewall.

Said sulculus is located at the bottom of reflector, and the below of this sulculus is provided with a through hole and extends base.

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 map of single glass of module of the utility model led light source with plating ceramic layer base.

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

The specific embodiment

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

As depicted in figs. 1 and 2; Single glass of module of a kind of led light source is with plating ceramic layer base; Said base comprises substrate 1 and is arranged on the reflector 2 on the substrate 1; The light-emitting area that is used to install led chip on the said reflector 2 is coated with a ceramic layer 21, and said substrate 1 and reflector 2 are to plate ceramic layer 21 after can adopting that metal material is one-body molded and processing, or reflector 2 is bonded and fixed on the substrate 1.The whiteness of said ceramic layer >=70; Be more preferred from >=85; The best is >=88.

Also be provided with the sulculus 3 that is used to install wiring board that extends into reflector sidewall 22 on the said substrate 1.

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 ceramic layer that plates high whiteness on the light-emitting area of reflector, can both meet the requirement of whiteness >=70 according to the prefabricated size that processes needs of production needs; Improve heat dispersion; 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 addition, the sulculus 3 in the foregoing description also can be located at the bottom of reflector 2, and below this sulculus 3, is provided with the both positive and negative polarity usefulness that a through hole extends base confession lead line plate, can reach the purpose of the utility model equally.
