(1) when making lamp body, by the thickness of thickening local glass, at convex mirror of inner surface formation of convex surface;
(2) paste a convex mirror separately at the inner surface of convex region face, make the inner surface of convex surface form a convex surface;
Second: the part at the convex surface outer surface is provided with concave curved surface, makes the outer shape of lamp body become the irregular curved surface that contains concave curved surface on the surface of convex surface, and the part of the inner surface of lamp body forms convex surface.The convex surface of lamp body can be the circular or oval-shaped hemisphere face in top, also can be other convex surfaces in irregular shape.Concave curved surface can be distributed in the outer surface of convex surface for one or more.
The LED bulb that there is light at above-described back plates reflective membrane on the convex surface of described convex surface inner surface.
There is the LED bulb of light at above-described back, and the material of described lamp body is glass or transparent resin.
There is the LED bulb of light at above-described back, and described lamp holder adopts plug-in type lamp holder or spiral lamp holder.
There is the LED bulb of light at above-described back, and the LED lamp in the described base is single or multiple, and is installed on the aluminium base.
There is the LED bulb of light at above-described back, is provided with radiating seat and power panel in the described base.
Implement the LED bulb that there is light at back of the present invention, have following beneficial effect:
1, adopts low-power consumption, high-efficiency LED as light source, can reach the effect of power saving, environmental protection, thereby reduce consumer's use cost.
2, by the reflection of convex mirror and concave curved surface to LED light, can make light reflex to the back side of lamp, thereby improve the illuminance at the bulb back side, eliminate the shadow at bulb back, make illumination of the present invention and excellent decoration effect.
3, lamp holder can be made direct insertion or spiral lamp holder, to satisfy the connection request of different use occasions.
4, simple structure of the present invention is easy to realize having effect in energy saving and environmental protection.
5, the design of aluminium base of the present invention, radiating seat and power panel is also original and different, embodies theories green, energy-conserving and environment-protective.
