Abstract:
1. A method for cascading and molding an LED filament support based on a support flitch, wherein the support flitch comprises a group of supports arranged in parallel and numbered as a first support, a second support, a third support, and so on, till an n-th support one after another; the support flitch still comprises two connection portions, the upper ends of all of the supports are integrated as a whole with the connection portions at the upper side of the support flitch, the lower ends of all of the supports are integrated as a whole with the connection portions at the lower side of the support flitch, a group of through holes are provided on the connection portions between the adjacent supports, the group of the through holes divide the connection portions between the adjacent supports into an inner connection side, a middle connection side and an outer connection side which are connected in parallel, wherein a first inner connection side, a first middle connection side and a first outer connection side are between a first support and a second support; a second inner connection side, a second middle connection side and a second outer connection side are between a second support and a third support; a third inner connection side, a third middle connection side and a third outer connection side are between a third support and a fourth support; therefore, an n−1th inner connection side, an n−1th middle connection side and an n−1th connection side are between an n−1th connection support and an n-th support; the portion of the support between the inner connection side and the middle connection side is an inner extension section, the portion of the support between the middle connection side and the outer connection side is an outer connection side, wherein the portion of the first support between the first inner connection side and the first middle connection side is a first inner extension section, the portion of the first support between the first middle connection side and the first outer connection side is a first outer extension section; the portion of the second support between the second inner connection side and the second middle connection side is a second inner extension section, the portion of the second support between the second middle connection side and the second outer connection side is a second outer extension section; the portion of the third support between the third inner connection side and the third middle connection side is a third inner extension section, the portion of the third support between the third middle connection side and the third outer connection side is a third outer extension section; therefore, the portion of an n−1th support between the n−1 inner connection side and an n−1th middle connection side is an n−1th inner extension section, the portion of the n−1th support between the n−1th middle connection side and the n−1th outer connection side is an n−1th outer extension section; the portion of an nth support between the n−1th inner connection side and the n−1th middle connection side is an nth inner extension section, the portion of the nth support between the n−1th middle connection side and the n−1th outer connection side is an nth outer extension section; it is characterized in that the method for cascading and molding the LED filament support based on the support flitch comprises the following steps: I. cutting out all of the inner extension sections in the connection portions at the upper side and the lower side, at this time, the middle connection side, the outer connection side and the outer extension section of each connection portion are all cut out and separated apart; II. cutting out the inner connection side which is in the connection portion at the upper side and of which the serial number is an even number; III. cutting out the inner connection side which is in the connection portion at the lower side and of which the serial number is an odd number; after the cutting out operation, a group of cascaded LED filament supports are obtained; or, the method for cascading and molding the LED filament support comprises the following steps: I. cutting out all of the outer extension sections in the connection portions at the upper side and the lower side, at this time, all of the outer connection sides are still cut out and separated apart; II. cutting out the inner connection side and the middle connection side which are in the connection portion at the upper side and of which the serial numbers are integer multiples of four; III. cutting out the inner connection side which is in the connection portion at the upper side and of which the serial number is an odd number; IV. cutting out the inner extension section which is in the connection portion at the upper side and of which the serial number is two, six, ten, and so on, wherein the tolerance of the serial number between the cut inner extension sections is four; V. cutting out the inner extension section which is in the connection portion at the upper side and of which the serial number is three, seven, eleven, and so on, wherein the tolerance of the serial number between the cut inner extension sections is four; VI. cutting out the inner connection side and the middle connection side which are in the connection portion at the lower side and of which the serial numbers are two, six, ten; the tolerance of the serial number between the cut inner connection sides is four; the tolerance of the serial number between the cut middle connection sides is four; VII. cutting out the inner connection side which is in the connection portion at the lower side and of which the serial number is an odd number; VIII. cutting out the inner extension section which is in the connection portion at the lower side and of which the serial number is one, five, nine, thirteen, and so on, wherein the tolerance of the serial number between the cut inner extension sections is four; IX. cutting out the inner extension section which is in the connection portion at the lower side and of which the serial number is four, eight, twelve, sixteen, and so on, wherein the tolerance of the serial number between the cut inner extension sections is four; after the cutting operation, two groups of cascaded LED filament supports are obtained; or, the method for cascading and molding the LED filament support comprises the following steps: I. cutting out all of the outer extension sections in the connection portions at the upper side and the lower side, at this time, the outer connection side is still cut out and separated apart; II. cutting out the inner extension section which is in the connection portion at the upper side and of which the serial number is an even number; III. cutting out all of the inner connection sides in the connection portion at the upper side; IV. cutting out the inner extension section which is in the connection portion at the lower side and of which the serial number is an odd number; V. cutting out all of the inner connection sides in the connection portion at the lower side; after the cutting operation, two groups of cascaded LED filament supports are obtained.
