Title:
LED BULB LAMP CAPABLE OF EMITTING LIGHTS IN ALL DIRECTIONS
Document Type and Number:
WIPO Patent Application WO/2014/201774
Kind Code:
A1
Abstract:
An LED bulb lamp capable of emitting lights in all directions comprises a light emitting portion and an electric connection portion. The electric connection portion and the light emitting portion are connected by using an insulation connection component (107). The light emitting portion consists of an upper transparent cover (101), a transparent bulb housing (103), and an LED light source (102). The LED light source (102) is mounted between the upper transparent cover (101) and the transparent bulb housing (103). The LED light source (102) is formed by adhering an LED chip (202) onto a transparent substrate (204) by using transparent crystal fixing glue (109). Blue lights emitted by the LED chip (202) excite fluorescent powder glue coated on the surface of the LED chip (202) or fluorescent ions doped on the upper transparent cover (101), the transparent bulb housing (103) or the transparent substrate (204) to generate yellow lights and red lights, and the yellow lights and red lights are combined with the blue lights to generate white lights. The light emitting range of the LED bulb lamp is close to 360 degrees, higher lighting effect can be obtained, and the defects that the electric connection is poor, the thermal conductivity is poor and the light emitting angle is small in a conventional large-angle light-emitting bulb lamp are effectively overcome; and the LED bulb lamp is suitable for large-scale popularization.
