Abstract

The utility model provides a base for an LED light source module, which includes a substrate and a plurality of reflective cups linearly arranged on the substrate, wherein the whiteness of the light-emitting area arranged on each reflective cup and used for installing an LED is not less than 70, preferably not less than 85, and optimally not less than 88; the substrate and the reflective cups of the base are made of ceramic or glass and are integrally formed through firing; and small slots extending to the side walls of the reflective cups and used for installing a circuit board are further arranged in the substrate. Through adopting the base provided by the utility model, the manufacture procedures of the reflective layer on the traditional LED metal base are reduced, so that the manufacturing technology is simplified, the manufacturing cost is greatly saved, and the mass industrialized production is facilitated; meanwhile, the base can be manufactured directly through adopting a precasted manner, the light extraction efficiency of an LED chip is greatly improved as the whiteness of the base is improved, as a result, the loss caused when the light energy is converted into thermal energy can be greatly reduced, and the heat radiation performance of the base is greatly improved, further, the LED lamp manufactured through adopting the base has excellent safety performance, is non-conductive and breakage-proof, and has greatly prolonged service life.

Description

The led light source module 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 the led light source module of heat dispersion to use base again.

The technical scheme that the utility model adopts is: a kind of led light source module is used base; Said base comprises substrate and is arranged on the some reflectors arranged in a straight line that have 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.

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: 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 the utility model led light source module 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.

A kind of led light source module is used base, and said base comprises substrate 1 and is arranged on the some reflectors arranged in a straight line 2 that have on the substrate 1, light-emitting area whiteness >=70 that are used to install 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 is to adopt pottery or glass to process, and reflector 2 is bonded and fixed on the substrate 1.Sidewall 22 positions of said adjacent reflector 2 are equipped with opening 21; Therefore form one group of reflector of strip; The bottom of the reflector at the two ends of this base is respectively equipped with circuit board slot 3; Below circuit board slot 3, also be provided with a through hole 31, the bottom of said circuit board slot 3 is lower than the bottom of reflector 2.Be convenient to after wiring board is installed equally with the reflector bottom, base described in the present embodiment is a strip, and reflector is 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, according to the prefabricated size that processes needs of production needs, can adopt the mould of making in advance to utilize one-shot forming technique; 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, can adopt prefabricated mode Direct Production base simultaneously, 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.
