Abstract

The utility model provides a base for a single-cup module of a light-emitting diode (LED) light source, which comprises a substrate and a reflection cup arranged on the substrate. The whiteness of a luminescent face of the reflection cup for installing an LED is larger than or equal to 70, preferably the whiteness is larger than or equal to 85, and optimally the whiteness is larger than or equal to 88. The substrate and the reflection cup of the base are fired in one time molding by ceramics or glass. The substrate is further provided with a small groove which extends into the lateral wall of the reflection cup and is used for installing a circuit board. The base for the single-cup module of the LED light source can reduce manufacture processes of reflection layers on a traditional LED metal base, thereby simplifying production processes, greatly saving production cost and facilitating mass industrial production. The base can be directly produced in precast mode, thereby improving the whiteness of the base, greatly improving light taking efficiency of the LED chips, greatly reducing loss caused by light energy converting into heat energy, and greatly improving radiation. An LED lamp made of the base is good in safety, free of conducting, not prone to be damaged and long in service life.

Description

Single glass of module of led light source is 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 single glass of module of led light source of heat dispersion to use base again.

The technical scheme that the utility model adopts is: single glass of module of a kind of led light source is used base; Said base comprises substrate and is arranged on the reflector on the substrate; Said base adopts the pottery of high whiteness or one-body molded the firing of glass to form; 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.

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: 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 map of single glass of module of the utility model led light source with 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.

Single glass of module of a kind of led light source is used base; Said base comprises substrate 1 and is arranged on the reflector 2 on the substrate 1; Said base is to adopt the pottery of high whiteness or glass is one-body molded is fired into; Perhaps also can be that substrate 1 is to adopt the pottery or the glass of high whiteness to process, again reflector 2 is bonded and fixed on the substrate 1.

Be used to install whiteness >=70 of the light-emitting area 21 of LED on the said reflector 2; 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 adopts the pottery or the glass base of high whiteness, according to the prefabricated size that processes needs of production needs, has both met 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 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.
