Embodiment Construction

[0014] Embodiment 1 of the present invention is a method in which 8 LED filaments are connected to each other and assembled into a wick on a glass stem. The LED filament series system includes 8 LED filaments and 9 metal filament spirals, such as Figure 4 As shown; the connection method between the leading end of the LED filament and the metal filament spiral is to insert the leading end of the filament into the spiral, and firmly bite the leading end of the filament by the deformation elastic force of the spiral, as shown in image 3 As shown in a; in order to install the filament series system on the stem, 7 filament hooks made of molybdenum wire are installed on the stem glass rod, divided into upper and lower layers, 3 on the upper layer near the stem plate, and 4 on the lower layer only if Figure 5 As shown; the method of installing the LED filament series system to the glass stem is as follows. First, the metal filaments drawn from the front "+" end of the above-menti...

Abstract

The invention provides a connection and installation method for LED filaments. The connection and installation method is used for assembling wicks in filament type LED bulbs. As the difference from the prior art of welding the lead-out ends of the LED filaments to a guide wire of a glass core column through a spot welding method, the electrode lead-out ends of the LED filaments are connected through elastic metal thin wire spiral parts, and therefore the LED filaments are connected in series one by one in an end-to-end manner according to the polarity to form a multi-joint LED filament series-connection system which can be bent. Then, the metal thin wire spiral parts at the head lead-out end and the tail lead-out end of the filament series-connection system are clamped on and fixed to corresponding core column side rod guide wires, and the metal thin wire spiral parts between the adjacent filaments are placed on corresponding filament hooks on the core column one by one so that the filaments can be arranged in order. By means of the connection and installation method, the defects that in the prior art, due to spot welding, the production efficiency is low, the finished product rate is low, and filament stress is large are overcome, and the production efficiency of filament type LED bulbs can be easily improved and the finished product rate of the filament type LED bulbs can be easily increased.

Description

Technical field [0001] The invention relates to a lighting appliance manufacturing technology, in particular to a method for connecting and installing an LED filament in a filament-type LED bulb. Background technique [0002] At present, the filament-type LED bulb that makes the LED lighting system into a filament (or light strip) has attracted more and more attention and attention from the lighting industry at home and abroad, because it has the following characteristics: 1. The lighting effect of its filament is similar to that of people. Familiar incandescent bulbs are very similar, and have the advantage of emitting light in all directions, which fundamentally eliminates the defect that conventional LED bulbs have directional light and cannot really replace incandescent lamps and energy-saving lamps; 2. The luminous efficiency is very high, and it is easy to make It can reach more than 110 lumens per watt, and the light decay is slow, the life is longer, and the energy s...
