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 high whiteness 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 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 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.
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.
