Problems solved by technology
Because the strip lighting is relatively slender, it is difficult to take out the formed cylindrical light source from the mold when the bracket and the surface of the light source are injection molded. Even if the light source can be taken out, it will easily deform the light source

The invention is applicable to the technical field of illumination and discloses manufacturing equipment for a long and thin columnar decorative lighting light source. The manufacturing equipment comprises an upper pressing die and a lower pressing die matched with the upper pressing die, wherein a U-shaped groove for containing a bracket with an LED chip is arranged on the lower pressing die; an arc groove opposite to the U-shaped groove is formed in the upper pressing die; the cross section of the arc groove is annular when the U-shaped groove is matched with the arc groove; an ejector needle which is as long as the U-shaped groove is arranged at the bottom of the U-shaped groove; the upper surface of an ejector bar is connected with the bottom of the U-shaped groove in a smooth manner in the injection molding process; the ejector needle raises from the bottom of the U-shaped groove when an upper die is separated from a lower die. When the upper pressing die is separated from the lower pressing die, the bar-shaped ejector needle synchronously raises, so that the bracket coated with a light transmitting layer is ejected from the bottom of the U-shaped groove of the lower pressing die to form a molding groove; and therefore, inverse die pulling or transformation when the light source is formed can be avoided; the molding efficiency is improved; the production cost is reduced.
Description
technical field [0001] The invention relates to the field of lighting technology, in particular to a manufacturing equipment for a slender columnar lighting source. . Background technique [0002] Since LED lighting uses LED as the light source and has better luminous efficiency, its application is becoming more and more extensive. [0003] In the existing LED lighting decorations, the LED light source is arranged on a heat-conducting substrate. The usual substrate is circular, and LED light-emitting chips can only be distributed on the circular substrate, and the circular light source can only be distributed. Because the strip lighting is relatively slender, it is difficult to take out the formed cylindrical light source from the mold when the bracket and the surface of the light source are injection molded. Even if the light source can be taken out, the light source will be easily deformed. Contents of the invention [0004] The main technical problem to be solved by t...
