LED BULB WITH LARGE LIGHT-EMITTING ANGLE AND METHOD FOR MANUFACTURING THE SAME

摘要

The invention relates to a LED bulb with large light-emitting angle and a method for manufacturing the same. The LED bulb with large light emitting angle comprises a lamp cap, a lamp base, an aluminum substrate, a lamp body and a lamp cover sequentially connected as an entity, an elastically deformable and recoverable reflector is arranged on the aluminum substrate. The reflector is an integrally-formed piece composed of a cylinder and a trumpet-shaped piece. An outer diameter of the reflector is bigger than an inner diameter of the lamp cover. The method for manufacturing a LED bulb with large light emitting angle comprises the following steps before fastening the lamp cover to the lamp body: squeezing a reflector, putting the reflector into the lamp cover, fixing the reflector to the aluminum substrate, and recovering the reflector to its initial shape through its own elasticity.
