The tube member includes a light-transmitting tube and one or more inner layers. The at least one flexible filament penetrates into the tube member. The light fixture comprises a light holder and the light tube. The at least one tube member includes a sealed end and a connecting end. The at least one tube member is mounted on the light holder. The light body comprises the light tube and a light cap. The light cap is fixedly connected with the connecting end of the at least one tube member. A drive power board is disposed in the light cap. Positive and negative pins of the drive power board are electrically connected with a top end and a side end of the light cap, respectively.

Light tubes, light fixtures, and light bodies

Light

A line lamp is provided, which includes a power connection assembly, a light transmissive housing and one or more lamp lines. Lamp lines includes a fixed end electrically connected with the power connection assembly and a free end provided with a first connecting member, free end, and the light transmissive housing is provided with a second connecting member matched with the first connecting member. The first connecting member is a first suction member; the second connecting member is a second suction member, and the first suction member is in suction connection with the second suction member. Or, the first connecting member is a first hooking member; the second connecting member is a second hooking member, and the first hooking member is hooked with the second hooking member.

Line lamp

A manufacturing method of an LED filament and a manufacturing method of a bulb are provided. The steps are as follows: step S, preparing a support; step S, fixing chips; step S, performing a first baking and performing a lighting test after cooling; step S, dispensing a glue in which a semi-finished product is covered with a covering glue, and a viscosity of the covering glue used is 5000 to 50000 mPa&#xb7;S; and step S, performing a second baking. According to the disclosure, the preparation of the LED filament is completed through support preparing, chip fixing, the first baking, dispensing and the second baking, and the covering glue selected during dispensing has good fluidity, and the fluorescent powders mixed in the covering glue can be uniformly dispersed, thus preventing precipitation or agglomeration and ensuring good light distribution.

Manufacturing method of LED filament and manufacturing method of bulb

A filament and a bulb are provided. The support in the filament includes a plurality of board bodies, and two adjacent board bodies are connected by a conductive connecting pin and an outer end of each of the board bodies at both ends is connected with a conductive pin. The bulb includes a lamp cap, a shell, a stem sealed with the shell, a conductive support fixed to the stem and a plurality of the LED filaments, the filaments are electrically connected to the conductive support.

LED filament and bulb

A lamp is provided, it includes a lamp body, a light-transmitting part, a light source and a power supply component. The lamp body includes a lamp base, the light source is mounted between the lamp base and the light-transmitting plate or mounted in a first cavity between the light-transmitting part and the lamp base, and the light source includes a filament which includes a power supply end electrically connected with the power supply component. The filament includes a plurality of LED chips connected in series, in parallel or in a mixed series-parallel manner. The filament or part of the filament is not in direct contact with the lamp base. Shapes of the light source of the lamp disclosed by the application varies, with better lighting effect and more design freedom at the same time.

Lamp

An omnidirectional LED light wire and a packaging method thereof, a light source and a lamp, and in particular, to the technical field of LED lighting. The omnidirectional LED light wire includes one or more than one flip chip and two or more than two conductive components. The one or more than one flip chip is connected through the conductive components to realize an electrical connection relationship, in single, in series, parallel or a combination of series and parallel, of the one or more than one flip chip. In view of technical problems of low efficacy, low temperature resistance and poor heat dissipation of the existing FPC substrate, the disclosure breaks bottlenecks of temperature resistance and dissipation of the FPC substrate.

Omnidirectional LED light wire and packaging method thereof, light source and lamp

Light bulb

A filament lamp lighting module and a manufacturing method thereof, the filament lamp lighting module comprise: at least two upper bridges with at least two bridge arms; and at least three lower bridges with at least one bridge arm; the lower bridge includes two rectifying bridges comprising rectifying bridge arms; the rectifying bridges are connected with the external power supply, the rectifying bridge arms are respectively connected with one ends of two rectifying diodes, and the other ends of the two rectifying diodes are respectively connected with different upper bridges to form a rectifying circuit; the lower bridge includes a bridge arm connected with one end of the filament, and the other end of the filament is connected with an upper bridge arm for rectifying and supplying power to the filament.

Filament lamp lighting module and manufacturing method thereof

The disclosure relates to a color-controllable LED luminescent lamp. By adopting a mini-LED chip with a small size to form an LED light source, the number of LED light sources that can be accommodated by a lamp shade is increased, so that the whole LED luminescent lamp can exhibit more types of colors and realize a free exhibiting and switching of multiple colors.
