Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The novel one embodiment of as depicted in figs. 1 and 2 this, including several LED lamp beads 100, substrate 200, heat dissipation
300 and 400 (not shown in figure 1) of lampshade, the front of substrate 200 be provided with reflective layer, LED lamp bead 100 and lampshade 400 are solid
Dingan County is loaded on the front of substrate 200, and lampshade 400 covers all LED lamp beads 100, and radiator 300 is fixedly installed in substrate 200
The back side；Lampshade 400 is transparent panel or translucent sheet, and the lampshade 400 includes and the one-to-one several hemisphere of LED lamp bead 100
The cup 410 of shape, LED lamp bead 100 are located at the inside of the opening of cup 410 and are located at the center of opening；The embodiment is also wrapped
Guide-lighting flexible glue 500 is included, guide-lighting flexible glue 500 covers LED lamp bead 100 and fills up the residue sky between cup 410 and substrate 200
Between.
The embodiment use with the one-to-one several hemispheric cups 410 of LED lamp bead 100, fill inside cup 410
Guide-lighting flexible glue 500, to form the secondary encapsulation structure to LED chip." cup-leaded light flexible glue " boundary of the secondary encapsulation structure
Face and " substrate-leaded light flexible glue " interface can reflect, reflect the light close to horizontal direction of the sending of LED lamp bead 100, allow this
Some light enters effective exit area, to improve luminous efficiency and reduce calorific value.Cup can also use other shapes,
