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 plating ceramic layer substrate LED bulb lamp of the band plastic casing of heat dispersion preferably again.

The technical scheme that the utility model adopts is: a kind of plating ceramic layer substrate LED bulb lamp with plastic casing, comprise lamp holder, support, led light source module, power unit and translucent cover, and the led light source module connects power unit through electric wire; Translucent cover also is equipped with in the surface of light source outside of led light source module; It is characterized in that: said LED bulb lamp also comprises a plastic casing, and an end of said support is fixedly connected plastic casing, and the other end is fixedly connected lamp holder; Plastic casing is set in the outside of led light source module; Said led light source module comprises base and led chip, and said base comprises substrate and is arranged at least one reflector on the substrate; The bottom of reflector is adhesively fixed with at least one led chip through insulating cement; The upper surface of said led chip is coated with fluorescent material and glue layer, and the light-emitting area that is used to install LED on the said reflector is coated with a high whiteness ceramic layer, the whiteness of said ceramic layer >=70.

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 is more preferred from >=and 85.

Whiteness the best of said ceramic layer is >=88.

The sidewall of said reflector also is provided with opening; Also be concaved with a circuit board slot on the said base; This circuit board slot extends to respectively in the opening of reflector sidewall, in the circuit board slot wiring board is installed, and said led chip is connected to through serial or parallel connection and draws both positive and negative polarity on the wiring board.

The below of said circuit board slot is provided with a through hole and extends base.

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

Said base and reflector are circle.

Compared with prior art; The utlity model has following advantage: after employing has the LED base plate for packaging of high whiteness, get optical efficiency and be greatly improved, so the heat dispersion of led light source module improves greatly; Can save the heat spreader structures in traditional LED; Directly adopt plastic casing, make whole lamp outside non-conductive, non-friable; Its security performance of LED lamp of processing is good, and weight lightens, and can save production cost greatly, helps large batch of suitability for industrialized production.

The specific embodiment

Come the utility model is carried out detailed explanation below in conjunction with specific embodiment.

Like Fig. 1, shown in 2; A kind of plating ceramic layer substrate LED bulb lamp with plastic casing; Comprise lamp holder 100, plastic casing 200, support 300, led light source module 400, power unit 500 and translucent cover 600; One end of said support 300 is fixedly connected plastic casing 200, and the other end is fixedly connected lamp holder 100, and plastic casing 200 is set in the outside of led light source module 400; Led light source module 400 connects power unit 500 through electric wire 501, and translucent cover 600 also is equipped with in the surface of light source outside of led light source module 400.

Like Fig. 3 and shown in Figure 4, be the structural representation of many glasss of modules of a kind of high whiteness substrate led light source, comprise base 10 and some led chips 20; Like Fig. 5 and shown in Figure 6, said base 10 comprises substrate 1 and is arranged on several reflectors 2 on the substrate 1, and led chip 20 is bonded and fixed at the bottom of reflector 2 through insulating cement; The upper surface of said led chip 20 is coated with fluorescent material and glue layer 40, and the sidewall 22 of said reflector 2 also is provided with opening 21, and the outside at reflector 2 on the substrate 1 also is provided with circuit board slot 3; Said circuit board slot 3 is " king " font; And extend into reflector sidewall 22, wiring board 30 is installed in the circuit board slot 3, said led chip 20 is connected on the wiring board 30 through serial or parallel connection and draws both positive and negative polarity; Base described in the present embodiment and reflector are circle, and said reflector is 6.

Said substrate 1 is to adopt one-body molded processing with reflector 2, or reflector 2 is bonded and fixed on the substrate 1.The light-emitting area that is used to install led chip on the said reflector 2 is coated with the ceramic layer 23 of a high whiteness, the whiteness of said ceramic layer 23 >=70; Be more preferred from >=85; The best is >=88.

In addition; Can also further below this circuit board slot 3, be provided with a through hole 31 and extend base in the foregoing description; Supply led chip 20 after serial or parallel connection is connected on the wiring board 30, pass this through hole again and draw both positive and negative polarity usefulness, can be more convenient during the routing of led chip in process of production; All leads all are encapsulated in fluorescent material and the glue layer the better purpose that must reach the utility model.

Because traditional general whiteness of LED metab is all less than 70; Therefore in actual production, need light-emitting area above that to increase the reflector layer production process; But do like this heat dispersion of LED base is reduced greatly, and increase production process, also increase production cost.The utility model adopts the base of the ceramic layer that is coated with 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, adopt above-mentionedly in addition, all be encapsulated in the inner encapsulating structure of reflector below glue and the fluorescent material mixed layer led chip and wiring board and the lead between them; Can in the operation of led chip encapsulation, just can accomplish in a direct step; 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.
