Corn lamp made of SMD lamp beads and conductive lines bent

Abstract

The invention discloses a patch lamp bead and electric conducting circuit bent corn lamp. The patch lamp bead and electric conducting circuit bent corn lamp is manufactured by the method steps of (a)mold pretreatment, (b) secondary punching, (c) bending: the one-standing and one-moving bending is performed; one standing: a static cutting board is arranged on one side of a rotary bending axis; a row of lamp beads and electric conducting metal among the lamp beads are pressed on the cutting board; and pressing pieces are pressing bars continuously spaced and with the heights of the lamp beads as step heights and bonded with rubber pad layers on the contacted surfaces; and one moving: a rotary bending plate is arranged on the other side of the rotary bending axis, and performs a rotary bending motion with the rotary bending axis as shaft; (d) assembly and light source molding, and (e) inner and outer insulation. An attachment heat dissipating plate of an aluminum substrate or a glass fiber plate or a flexible plate is saved, so that the production process and the production cost are greatly reduced; the process difficulty of mold opening through LED energy saving lamp punching and the like is reduced, so that later procedures of the production process are guaranteed; and the LED energy saving lamp bending and assembly processes are more precise to guarantee the product quality.

Description

technical field [0001] The invention relates to the technical field related to the manufacture of energy-saving lamps, in particular to an LED energy-saving lamp in which chip lamp beads are mounted on a metal conductive circuit and the conductive circuit is bent into a corn shape. Background technique [0002] Since LEDs have been used for lighting, the forms of lighting fixtures have become more diverse. For those lamps that are not convenient to install radiators, they usually use the attachment of aluminum substrates, glass fiber boards or flexible boards for natural heat dissipation. For this natural Heat-dissipating LED lamps usually use large-area chip lamp beads or a large number of lamp beads to reduce the junction temperature as much as possible. For this type of LED lamps, the heat dissipation area of ​​aluminum substrate or glass fiber board is usually relatively large, so as to meet the requirements of LED lamps. In normal use, during the production process of c...

[0002] Since LEDs have been used for lighting, the forms of lighting fixtures have become more diverse. For those lamps that are not convenient to install radiators, they usually use the attachment of aluminum substrates, glass fiber boards or flexible boards for natural heat dissipation. For this natural Heat-dissipating LED lamps usually use large-area chip lamp beads or a large number of lamp beads to reduce the junction temperature as much as possible. For this type of LED lamps, the heat dissipation area of ​​aluminum substrate or glass fiber board is usually relatively large, so as to meet the requirements of LED lamps. In normal use, during the production process of corn-shaped LED energy-saving lamps, due to the large area of ​​the aluminum substrate and the large number of lamp beads of this lamp, the cost of the whole lamp remains high, which affects the popularization and use
