Description

Technical Field

[0001] This utility model belongs to the field of LED lighting technology, and more specifically, relates to a multi-color filament lamp. Background Technology

[0002] Filament lamps are widely used in lighting and decoration due to their high efficiency, energy saving, long service life, and retro and beautiful appearance. Traditional filament lamps usually use a single color light source. Although some degree of color change can be achieved through coatings or external filters, these methods have disadvantages such as high energy loss, limited color effect, and difficulty in precise control, which cannot meet diverse decorative needs. Multi-colored filament lamps usually use flexible light strips, but flexible light strips generally use flip-chip and flexible FPC substrates, which makes the manufacturing cost high. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-color filament lamp that can achieve adjustable filament lamp color and reduce material costs.

[0004] This utility model discloses a multi-color filament lamp, including a core column, on which one or more filament strips are fixedly arranged. The filament strips are arranged around the outer periphery of the core column, and the filament strips include red light source, green light source, blue light source, cool white light source and warm white light source; the light source modules are arranged in an alternating manner.

[0005] As a further improvement of this utility model, the red light source, green light source, blue light source, cool white light source and warm white light source are all independent filament light source modules, forming different filament strips.

[0006] As a further improvement of this utility model, the filament strip is a straight rigid filament.

[0007] As a further improvement of this utility model, the filament strip also includes a substrate, and each light source module is arranged on the upper surface and / or lower surface of the substrate to form a corresponding ceramic filament.

[0008] The substrate can be a ceramic substrate, a glass substrate, or a ceramic-aluminum substrate.

[0009] As a further improvement of this utility model, the various light source modules are connected in series, in parallel, or in a mixed series-parallel connection.

[0010] As a further improvement of this utility model, it also includes a housing, a filament strip arranged inside the housing, a core column forming a sealed cavity with the housing, and an inert gas being filled into the cavity through the core column.

[0011] As a further improvement of this utility model, the corresponding extreme ends of the filament strip are electrically connected to the built-in or external driving power supply respectively through the connecting wires provided on the core column.

[0012] As a further improvement of this utility model, five filament strips are provided.

[0013] As a further improvement of this utility model, the filament strips are evenly distributed on the outer periphery of the core column.

[0014] As a further improvement of this utility model, the core post is located at the exact center of the shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By integrating red light source, green light source, blue light source, cool white light source or warm white light source into the filament strip and designing it as an independent filament light source module, the light source modules are arranged in an alternating manner, which can achieve a rich color combination and meet the diverse needs of different scenes for lighting effects;

[0017] 2. By using straight rigid filaments instead of traditional flexible light strips, the high manufacturing costs of flip chips and flexible FPC substrates are avoided, thus significantly reducing material costs;

[0018] 3. Using ceramic substrates, glass substrates, or ceramic-aluminum substrates as the substrate for the filament strip provides excellent heat dissipation performance and mechanical strength, improving the service life and overall stability of the filament strip. Attached Figure Description
