Example IV:
With reference to Fig. 1 and Fig. 3.In another embodiment of the present invention, a kind of lamps and lanterns are uniform outer for realizing the leaded light
Shell, comprising: cosmetic sheet 100 for shutting out the light, for light guide 200 derived from light and the LED for emitting beam
Lamp bead 300.
The cosmetic sheet 100 is installed on the light guide 200.The inner surface of the light guide 200 is curved surface, described to lead
LED lamp bead 300 is provided at the corresponding sphere center position of the inner surface of body of light 200.The light guide 200 is by 300 institute of LED lamp bead
The light of sending is directed to a bit on the light guide 200.The portion of the light guide 200 is blocked using the cosmetic sheet 100
The irradiation area of light is penetrated in dispersion.Wherein, in embodiments of the present invention, the light guide 200 is integrally formed, the light guide
200 outer surface preferably uses cambered design, and the inner surface of the light guide 200 is using the smooth curved surface convenient for reception light
Design.Wherein, the top of the light guide 200 is machined with depressed section, is machined with locating slot on the edge of the depressed section,
The locating slot is circular ring shape.
In embodiments of the present invention, in order to enable the leaded light of LED lamp bead 300 accomplishes the effect of even light-guiding, so that described
The installation site of LED lamp bead 300 is located at the sphere center position of the light guide 200, is so that the LED lamp bead 300 reaches
The distance at 200 top of light guide, reaches being equidistant for two sides inner edge with the LED lamp bead 300, so that LED lamp bead 300
Light be radiated at the inner surface of the light guide 200, light is directed to the top of the light guide 200 by inner surface.
In conjunction with Fig. 4.When the light guide 200 is the shelling machine of the longer hemisphere face structure in both sides, it is preferred to use the LED lamp bead
300 are set in the sphere center position in the light guide 200.Refer to, the judgement of the sphere center position of the light guide 200 is to push up
Portion does vertical line for any and drafts center point, and taking center point to reach top is radius, the distance phase of acquirement center point to both ends
Whens equal, at this point, the center point drafted is the fixation position of optimal LED lamp bead 300.
The uniform shell of leaded light described in the embodiment of the present invention, mainly there is following technical effect:
The uniform shell of leaded light described in the embodiment of the present invention, comprising: cosmetic sheet 100 for shutting out the light is used for
Light guide 200 derived from light and the LED lamp bead 300 for emitting beam.The cosmetic sheet 100 is installed in the leaded light
On body 200.The inner surface of the light guide 200 is curved surface, is set at the corresponding sphere center position of inner surface of the light guide 200
It is equipped with LED lamp bead 300；The light that LED lamp bead 300 is issued is directed to one on the light guide 200 by the light guide 200
Point；The irradiation area of some scattered light of the light guide 200 is blocked using the cosmetic sheet 100.By using light guide 200
Inner surface is embedded in the structure of transistor, carries out leaded light to light using transistor, enhances the light guide effect of light guide 200.Together
