Abstract

The invention provides a base for a multi-cup module of an LED (Light Emitting Diode) light source. The base comprises a base plate and a plurality of light reflecting cups, and the whiteness of a luminous surface of each light reflecting cup is larger than or equal to 70, preferably 85, more preferably 88, wherein the luminous surface is used for mounting an LED. The base plate and the reflecting cups of the base are made of ceramic or glass through integral formation, the base plate is further provided with small slots for mounting circuit boards, and the small slots extend to the sidewalls of the light reflecting cups. According to the multi-cup module of the LED light source, disclosed by the invention, the manufacturing process of light reflecting layers on a traditional LED metal base can be reduced, the production technique is simplified, the production cost can be largely saved, and the industrial production in large batch is facilitated; simultaneously, the base can be directly manufactured by a prefabricating manner, and the luminescence efficiency of the LED chip is largely increased after the whiteness of the base is increased, thus the loss of the conversion from optical energy to heat can be largely reduced, the heat dissipation performance of the LED chip can be largely improved, and the LED lamp manufactured by the LED chips has good safety and largely prolonged service life, does not conduct electricity and is not easy to be broken.

Description

Many glasss of module bases of led light source

Technical field

The present invention relates to a kind of lighting apparatus, relate 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, various lighting devices now have been widely used in, 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 to be solved in the present invention is to provide a kind of and can either saves production cost, can keep many glasss of module bases of led light source of heat dispersion preferably again.

The technical solution used in the present invention is: many glasss of module bases of a kind of led light source, described base comprise substrate and the some reflectors that are arranged on the substrate, it is characterized in that: light-emitting area whiteness 〉=70 that are used to install LED on the described reflector.

Described base adopts pottery or one-body molded the firing of glass to form, and perhaps substrate is to adopt pottery or glass to make, and reflector is bonded and fixed on the substrate.

The light-emitting area whiteness that is used to install LED on the described reflector is more preferred from 〉=and 85.

Be used on the described reflector to install that the light-emitting area whiteness of LED is best is 〉=88.

The sidewall of described reflector also is provided with opening, also is concaved with a circuit board slot on the described base, and this circuit board slot extends to respectively in the opening of reflector sidewall, and circuit board slot below also is provided with a through hole.

The bottom of described circuit board slot is lower than the bottom of reflector.

Described base and reflector are circle.

Described reflector is 6, and described circuit board slot is " king " font.

Compared with prior art, the present invention 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, both simplified production technology, can save production cost greatly, help large batch of suitability for industrialized production, can adopt prefabricated mode directly to produce base simultaneously; The inventor finds through long-term a large amount of experiment in addition, the whiteness of its base reflective surface is increased to 〉=70, can promote well and get optical efficiency, and the heat dispersion excellence; 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 making, also improve greatly non-friable service life.

Description of drawings

The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the overall structure schematic diagrames of many glasss of modules of led light source of the present invention with base.

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

The specific embodiment

The present invention will be described in detail below in conjunction with specific embodiment.

Many glasss of module bases of a kind of led light source, described base comprises substrate 1 and 6 reflectors 2 that are arranged on the substrate, also be provided with opening 21 on the sidewall 22 of described reflector 2, also be concaved with a circuit board slot 3 on the described base, described 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 described reflector 2; Be more preferred from 〉=85; The best is 〉=88.

Described base adopts pottery or one-body molded the firing of glass to form, and perhaps substrate 1 is to adopt pottery or glass to make, and reflector 2 is bonded and fixed on the substrate 1 again.The bottom of described 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 thereon 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 present invention 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 producing the prefabricated size that processes needs of needs, burn out the concrete shape that has reflector, opening, circuit board slot and through hole that needs, 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 directly to produce base, production efficiency will improve greatly.

In the foregoing description, the shape of described base also is not limited to circle, can do shapes such as squarely or strip, still can reach aforesaid goal of the invention.
