Embodiment 1

[0041] refer to figure 1 , the present embodiment provides a self-supporting LED filament without shadow, and the LED filament includes a transparent PCB board 5, a plurality of LED chips 6 located on the PCB board 5 and covering the PCB board 5 and the LED chips 6 Fluorescent glue on the periphery.

[0042] The PCB board 5 has two parts, the first area 18 and the second area 19, and the width of the first area 18 is greater than the width of the second area 19, the first area 18 is inserted into the lamp holder 3 of the LED lamp, And it is fixedly connected with the lamp holder 3 , the LED chip 6 is disposed on the side of the second area 19 , and the first pad 8 and the second pad 9 are disposed on the first area 18 . The first pad 8 and the second pad 9 serve as the input end and the output end of the LED filament respectively, and are connected to the power supply through the positive line and the negative line. Since the first welding pad 8 and the second welding pad 9 ...

Embodiment 2

[0051] refer to image 3 , the present embodiment provides a self-supporting LED filament without shadow, including a transparent PCB board 5 , a plurality of LED chips 6 mounted on the PCB board and a control circuit 10 .

[0052] The PCB board 5 has two parts, the first area 18 and the second area 19, and the width of the first area 18 is greater than the width of the second area 19, the first area 18 is inserted into the lamp holder 3 of the LED lamp, And it is fixedly connected with the lamp holder 3, the LED chip 6 is arranged on the side of the second area 19, the control circuit 10 is arranged on the side of the first area 18, and the first area 18 is provided with The first pad 8 and the second pad 9 .

[0053] The first area 18 and the second area 19 have conductive patterns, and the LED chip 6 is electrically connected to the circuit inside the lamp holder 3 through the conductive patterns.

[0054] In addition, a plurality of LED chips 6 are evenly arranged in a m...

Embodiment 3

[0060] refer to Figure 4 , the present embodiment provides a self-supporting LED filament without shadow, including a transparent PCB board 5 , a plurality of LED chips 6 mounted on the PCB board and a control circuit 10 .

[0061] The PCB board 5 has two parts, the first area 18 and the second area 19, and the width of the first area 18 is greater than the width of the second area 19, the first area 18 is inserted into the lamp holder 3 of the LED lamp, And it is fixedly connected with the lamp holder 3, the LED chip 6 is arranged on the side of the second area 19, the control circuit 10 is arranged on the side of the first area 18, and the first area 18 is provided with The first pad 8 and the second pad 9 . Since the width of the first area 18 is greater than the width of the second area 19, after the first area 18 is installed in the lamp holder 3 of the LED lamp, the self-support of the PCB board 5 is more firm, and the connection between the first area 18 and the secon...

Abstract

The invention relates to a self-supporting shadow-free LED lamp filament and an LED lamp. The LED lamp filament is used for assembling the LED lamp. The LED lamp filament comprises a transparent PCB, a plurality of LED chips and fluorescent glue covering the periphery of the PCB and the periphery of the LED chips, wherein the PCB is provided with a first area and a second area, the first area is inserted into a lamp holder of the LED lamp and fixedly connected with the lamp holder, and the LED chips are arranged on one side of the second area; and the first area and the second area are provided with conductive patterns, and the LED chips are electrically connected with a circuit in the lamp holder through the conductive patterns. The beneficial effects are that the LED lamp filament integrating the PCB and a support is adopted, so that shadows and light spots cannot be caused when the support or a core column shields a light emitting body when the LED chip emits light, and the display effect of the LED lamp is improved.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to an LED filament without a bracket and without shadows and an LED lamp. Background technique [0002] With the improvement of people's living standards, people's demand for lighting is no longer just for lighting, but gradually pays attention to the experiential nature of lighting. Demand, LED filaments, bulbs, and lamps all need to have higher quality and more forms. [0003] Traditional LED lamps include multiple filaments, and multiple filaments need to be supported in the bulb of the lamp with brackets, and the brackets will block part of the filaments from emitting light and form shadows, which will affect the final display effect; at the same time, in order to achieve intelligence (color and Dynamic transformation), the LED filament needs to realize the output of multiple signals, and the current technology realizes high cost and poor effect. [0004] Therefore,...
