Abstract

The utility model provides a base for a light-emitting diode (LED) light source multi-cup module, comprising a substrate and a plurality of reflective cups which are arranged on the substrate; the whiteness of light-emitting surfaces on the reflective cups which are used for installing LEDs is more than or equal to 70, preferably more than or equal to 85, and more preferably more than or equal to 88. The substrate and the reflective cups of the base are integrally burned from ceramics or glass, and small grooves which extend into the side walls of the reflective cups and are used for installing circuit boards are arranged on the substrate. According to the base for the LED light source multi-cup module, a procedure for manufacturing a reflective layer on a traditional LED metal base can be reduced, so that not only a production process is simplified, the production cost can be greatly saved, mass industrial production is benefited, but also the base can be directly manufactured through a prefabrication method; because the light extraction efficiency of an LED chip is greatly improved after the whiteness of the base is improved, the loss in the conversion of light energy into heat energy can be greatly reduced, the radiating performance is greatly improved, an LED lamp which is manufactured from the base has good safety performance, does not conduct power, is not easy to break, and has far longer service life.

Description

Many glasss of modules of led light source are used 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 preferably many glasss of modules of led light source of heat dispersion to use base again.

The technical scheme that the utility model adopts is: many glasss of modules of a kind of led light source are used base; Said base comprises substrate and is arranged on the some reflectors on the substrate; It is characterized in that: 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; Circuit board slot below also is provided with a through hole; Said base adopts the pottery of high whiteness or one-body molded the firing of glass to form, and perhaps substrate is to adopt the pottery or the glass of high whiteness to process, and reflector is bonded and fixed on the substrate.

Be used to install light-emitting area whiteness >=70 of LED on the said reflector, be more preferred from >=85, the best is >=88.

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: owing to substrate and reflector adopt with pottery or glass through one-body molded fire the high whiteness LED base that forms after; 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 the whiteness of base improves, the getting optical efficiency and will promote greatly of led chip, therefore can significantly reduce luminous energy is converted into heat energy loss; Therefore its heat dispersion also will improve greatly; Good, non-conductive with its its security performance of LED lamp of processing, 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 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 used base; Said base comprises substrate 1 and is arranged on 6 reflectors 2 on the substrate, also is provided with opening 21 on the sidewall 22 of said reflector 2, also is 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, and circuit board slot 3 belows also are provided with a through hole 31, is used to install light-emitting area whiteness >=70 of LED on the said reflector 2; Be more preferred from >=85; The best is >=88.

Said base adopts pottery or one-body molded the firing of glass to form, and perhaps substrate 1 is to adopt pottery or glass to process, and reflector 2 is bonded and fixed on the substrate 1 again.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 adopts the pottery or the glass base of high whiteness; Can adopt the mould of making in advance to utilize one-shot forming technique according to the prefabricated size that processes needs of production needs, burn out the concrete shape that has reflector, opening, circuit board slot and through hole that needs, both meet 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.
