Abstract
The utility model provides a ceramic-layer-plated base of an LED (Light-emitting Diode) light source module. The base comprises a substrate and a plurality of light reflection cups which are arranged on the substrate and are arrayed in a straight line, wherein a ceramic layer is plated on a light-emitting surface for installing an LED is each light reflection cup; the whiteness of each ceramic layer is more than or equal to 70; more preferably, the whiteness is more than or equal to 85; and mostly preferably, the whiteness is more than or equal to 88. The substrate is further provided with small slots which stretch into the side walls of the light reflection cups and are used for installing a circuit board. According to the utility model, the manufacturing procedure of a light reflection layer on a traditional LED metal base can be reduced, so that not only is the production process simplified, but also the production cost is greatly saved, and the ceramic-layer-plated base can be industrially produced in batches; meanwhile, the base can be directly produced by using a prefabrication way; after the light reflection cups on the base are plated by the high-whiteness ceramic layers, the light extraction efficiency of LED chips is greatly increased, so that the loss caused by converting light energy into heat energy is greatly reduced and the heat radiation performance is greatly improved; and an LED lamp which is produced by using the ceramic-layer-plated base has the advantages of good safety performance, non-conductive performance, low possibility of crush and greatly-prolonged service life.
Description
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 the led light source module usefulness plating ceramic layer base of heat dispersion preferably again.
The technical scheme that the utility model adopts is: a kind of led light source module is with plating ceramic layer base; Said base comprises substrate and is arranged on the some reflectors arranged in a straight line that have on the substrate, and 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 locations of said adjacent reflector is equipped with opening, forms one group of reflector of strip, and the bottom of the reflector at the two ends of this base is respectively equipped with the circuit board slot, below the circuit board slot, also is provided with a through hole.
The bottom of said circuit board slot is lower than the bottom of reflector.
Said base is a strip, and reflector is circular.
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 the utility model led light source module 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.
A kind of led light source module is with plating ceramic layer base; Said base comprises substrate 1 and is arranged on the some reflectors arranged in a straight line 2 that have 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 23, the whiteness of said ceramic layer >=70; Be more preferred from >=85; The best is >=88.Said substrate 1 and reflector 2 can be to adopt that metal material is one-body molded to be processed, and perhaps also can be that reflector is bonded and fixed on the substrate.
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 the foregoing description, the shape of said base also is not limited to annular, can do shapes such as quadrate or rectangle, still can reach aforesaid utility model purpose.
