Abstract

The invention relates to an LED (light emitting diode) lamp filament arrangement structure capable of improving light intensity and an LED filament lamp. The LED lamp filament arrangement structure comprises an even number of lamp filament type LED modules arranged on a core column support, wherein the lamp filament type LED modules are paired and intersected to each other; an included angle theta between each two lamp filament type LED modules which are intersected to each other is 30-40 degrees; and the distance (d) from the intersected point of each two lamp filament type LED modules which are intersected to each other to the top of the lamp filament type LED module accounts for 44%-53% of the length (D) of each lamp filament type LED module. The LED filament lamp comprises a bulb shell, the core column support and a lamp holder which are connected to one another; and the core column support is provided with the LED lamp filament arrangement structure. The light intensity of space in a range from an angle of minus 30 degrees to an angle of 30 degrees on the top of the LED filament lamp is greater than the light intensity of the center of the LED filament lamp by 50%, so that a beam angle can be confirmed and is greater than 270 degrees, the light intensity of the LED filament lamp is improved effectively, and relevant standard requirements are met.

Description

technical field [0001] The invention relates to an LED filament lamp, in particular to an LED filament arrangement structure and an LED filament lamp for improving luminous intensity. Background technique [0002] In order to achieve the purpose of energy saving, LED lamps are becoming more and more popular, and various LED lamps have appeared on the market, among which there are LED filament lamps that can replace incandescent lamps, which are connected by bulbs, stems and lamp caps. Such as figure 1 As shown, multiple filament-type LED modules 1' are installed on the stem 2', and the filament-type LED modules are arranged obliquely to form a cone shape. The filament-type LED modules are formed by connecting many LED lamp beads, arranged Form a long strip and connect with the power supply circuit outside the blister through the guide wire. Such as figure 2 As shown, the luminous intensity between -30° and 30° at the top of this LED filament lamp is too low, and the curv...
