Problems solved by technology

The existing filaments all use LED chip and phosphor technology, through the combination of phosphor technology and LED chip, the effect of the filament emitting light of different colors is achieved, and then the filament is installed in a transparent glass bulb for use, but for consumers, When the filament does not emit light, the internal filament structure will be directly seen through the transparent glass bulb, which will affect the senses of consumers and the aesthetics of indoor lamps

Embodiment 1

[0039] Such as figure 1 As shown, a filament includes a substrate 1, a plurality of LED chips 2, a fluorescent colloid layer 3 and a light-transmitting appearance layer 4, a plurality of LED chips 2 are electrically connected in series, in parallel or in series and parallel combinations, and a plurality of LED chips 2 are installed on the substrate 1 Above, the fluorescent colloid layer 3 is arranged on the outer surface of the LED chip 2, the light-transmitting appearance layer 4 is arranged on the outer surface of the light-transmitting colloid layer, and the light-transmitting appearance layer 4 includes any of milky white appearance layer 5 and black appearance layer 6. one or more.

[0040] Wherein, the LED chip 2 is any one of a front chip, a flip chip, a vertical chip or a CSP package chip, and the LED chip 2 is any one of a red chip, a green chip or a blue chip, so that when the LED chip 2. When emitting light, through the fluorescent colloidal layer 3, light with the...

Embodiment 2

[0046] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the light-transmitting appearance layer 4 of this embodiment is a milky white appearance layer 5. At this time, the overall filament is milky white, and the same selection powder of titanium dioxide in the milky white appearance layer 5 occupies The ratio is set at 1% mass ratio, so that the filament can reach the filament brightness required for normal lighting, and ensure the aesthetic appearance of the filament without affecting the actual luminous efficiency of the filament, meeting the basic needs of users for the brightness of the filament.

Embodiment 3

[0048] Such as Figure 4As shown, the difference between this embodiment and Embodiment 1 is that the light-transmitting appearance layer 4 of this embodiment is a black appearance layer 6. At this time, the filament appears black as a whole, and the carbon powder of the black appearance layer 6 is the same selection powder When the ratio is set to 0.032% by mass, the filament can be set as a sleep lamp for the bedroom at this time, which meets the lighting brightness of the filament required by the user, and ensures the aesthetics of the filament without affecting the actual luminous efficiency of the filament, which meets the needs of the user. The basic needs of the operator for the brightness of the filament.

Abstract

The invention relates to the technical field of illumination, in particular to a filament and a filament manufacturing method.The filament comprises a substrate, a plurality of LED chips, a fluorescent gelatinous layer and a light-transmitting appearance layer, wherein the LED chips are electrically connected in series or in parallel or in series-parallel combination, the LED chips are installed on the substrate, the fluorescent gelatinous layer is arranged on the outer surfaces of the LED chips. The light-transmitting appearance layer is arranged on the outer surface of the fluorescent gelatinous layer, the appearance attractiveness of the filament is improved, and the bottleneck that the appearance of consumers is affected due to the visible internal structure of the filament is broken through.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a filament and a method for manufacturing the filament. Background technique [0002] With the rapid development of lighting technology, the pursuit of light source shape and color is getting higher and higher. The existing filaments all use LED chip and phosphor technology, through the combination of phosphor technology and LED chip, the effect of the filament emitting light of different colors is achieved, and then the filament is installed in a transparent glass bulb for use, but for consumers, When the filament does not emit light, the internal filament structure will be directly seen through the transparent glass bulb, which will affect the senses of consumers and the aesthetics of indoor lamps. Contents of the invention [0003] Aiming at the shortcomings in the prior art, the present invention provides a filament and a manufacturing method for the filament, which has t...
