Abstract

The invention discloses an LED illuminating lamp with an adjustable emergent light divergence angle. The LED illuminating lamp comprises a flexible PCB, a plurality of LED lamp bodies, a lamp holder, a rotating portion and a supporting seat. The flexible PCB is provided with a plurality of contracting bands in the radial direction, at least one contracting ring is arranged on the inner circumference of the flexible PCB, and a pull rod is arranged in the center of the lower surface of the flexible PCB in a downward extending mode. The LED lamp bodies are arranged on the upper surface of the flexible PCB at intervals. A containing cavity with one open side is formed in the lamp holder, and through holes are formed in the bottom of the lamp holder; the lamp holder is provided with a circular side wall, and an external thread is arranged on the outer portion of the side wall. The rotating portion is in threaded connection with the lamp holder. The supporting seat is arranged in the containing cavity. The bottom of the flexible PCB is arranged on the circular end face of the rotating portion in a covering mode, and the lower end of the pull rod is arranged on the supporting seat. The technical problem that the emergent light divergence angle of an LED illuminating lamp cannot be adjusted is solved.

Description

Technical field [0001] The present invention relates to a lighting lamp, more specifically, the present invention relates to an LED lighting lamp with adjustable light divergence angle. Background technique [0002] LED (Light Emitting Diode) lighting is a lighting fixture made of the fourth-generation green light source LED. LED is known as the fourth-generation lighting source or green light source. It has the characteristics of energy saving, environmental protection, long life, small size, etc., and can be widely used in various indications, displays, decorations, backlight sources, general lighting and urban night scenes. [0003] The disadvantage of the current LED lighting lamps on the market is that the divergence angle of the lighting lamps is not adjustable, which limits the application range of the LED lighting lamps. Summary of the invention [0004] An object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantag...
