Embodiment

Describe the embodiment of the utility model LED resin light-emitting character panel in detail below in conjunction with accompanying drawing.

In the accompanying drawing, the mark of part is as follows:

1-shell, 2-illuminating source, 3-bottom: fixed bed, 4-middle layer: even photosphere, 5-surface layer: dyed layer.

Referring to figs. 1 through Fig. 3, the utility model LED resin light-emitting character panel comprises the housing 1, illuminating source 2 and the casting packed layer that have literal and/or pattern.Housing 1 adopts injection molding or sheet metal to be welded.Housing 1 is used to protect the potting resin casting and keeps its solid forms, and internal light is advanced reflection effectively, avoids the luminous energy waste.

The casting packed layer comprises fixed bed 3 from inside to outside, even photosphere 4 and dyed layer 5.Fixed bed 3 in the packing material plays the effect of insulating between protection to illuminating source 2 and circuit thereof, fixing and circuit.Even photosphere 4 guarantees penetrating of light and evenly diffusion.Dyed layer 5 is final visual parts, can cooperate different glow color illuminating sources 2 to mix colours according to request for utilization, realizes the FINAL APPEARANCE effect.

Illuminating source 2 and circuit install and fix in housing 1 bottom, can be divided into forward light projector, light projector and three kinds of fixed forms of side direction light projector dorsad according to operating position.Illuminating source 2 adopts some high brightness solid semiconductor light-emitting-diodes, high brightness solid semiconductor light-emitting-diode and connection lead thereof adopt resin cast to be solidificated in the fixed bed 3, its power consumption is low, long service life has been eliminated the defective that traditional acrylic plastic uptake light-emitting character panel and neon bulb light-emitting character panel power consumption are big, serviceable life is short.
