The beneficial effect of the technical scheme that the utility model embodiment provides is: the utility model, by be provided with loophole on support, can increase reflection, the refraction area of filament like this, makes filament lighting at two sides reach better effect, improves the brightness at the filament back side.Be engaged between the sawtooth of support simultaneously and be provided with groove, can further increase reflection, refraction effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the full angle light-emitting filament of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment one is described further.
The utility model proposes a kind of full angle light-emitting filament, its structure as shown in Figure 1, comprises support 1 and is fixed on the surperficial luminescence chip 2 of described support; Described rack surface is provided with the loophole 3 that runs through the above support.Wherein, this loophole 3 can be circular or square or triangle, or other any shapes.As shown in Figure 1, wherein, described support 1 outer surface becomes concavo-convex alternate engrail or wavy, and is provided with groove between two adjacent sawtooth.Certainly, going back support 1 can be that any shape or described support 1 are arc.Wherein, described luminescence chip 2 is red light chips or blue chip or purple light chip or green glow chip, or the chip of other any light.This support 1 connects pin 6 by PPA material 5, and described pin 6 is electrically connected with described luminescence chip 2.Concrete, and described pin 6 welds to be electrically connected with described luminescence chip 2 by metal wire 4.
In order to promote illuminating effect, be provided with phosphor powder layer (not shown) at the outer surface of described support.Concrete, the generating mode of this phosphor powder layer can specifically comprise: together with fluorescent material is fitted over glue and stir, and vacuumizing and defoaming; Deployed fluorescent glue is coated on described support by 360 ° of plastic packaging (molding) modes.Wherein, this fluorescent material can be also ruddiness or blue light or purple light or green glow, or other any colors.
In above-mentioned the utility model embodiment, this support can be made by metal or microcrystal glass material.
At present illuminating industry generally uses edge vertical bar support linearly, and the low and reflection of its back side brightness, refraction area are little, and around shading surface large, dispel the heat bad.The utility model adopts zigzag or wavy support, and metal or devitrified glass material are manufactured support.Meanwhile, the shape of support can also be made to arcuation or arbitrary shape, depend on any one shape as support wherein.Be provided with multiple loopholes that run through rack body at support, this loophole can be one or more.Each luminescence chip is all fixed on to rack surface, and utilizes 360 ° of full technique for packing that deployed phosphor powder layer is coated on support uniformly on the support that is fixed with chip.Chip can increase illuminating effect by the reflection of fluorescent material and support itself, refraction like this.In the time that adopting laciniation, rack surface can form multiple grooves simultaneously, groove fit loophole can further increase reflection, refraction area and reflection, the refractive index of full angle light-emitting filament, make filament lighting at two sides reach better effect, improve the luminous efficiency at the filament back side.
Further, this luminescence chip can be for sending luminescence chip or other section's glow color chips of blue light, ruddiness, purple light, green glow, can be provided with wherein one or more can luminescence chip simultaneously, ceaselessly reflect, reflect and improve chip light emitting efficiency with excitated fluorescent powder, thus the luminous efficiency of raising filament.
Further, the utility model directly utilizes metal or micro crystal material as support, a part of heat can be derived by metal pins, can improve the current filament bad problem of dispelling the heat.Utilize 360 ° of full technique for packing of molding formula that deployed fluorescent material glue is coated on support, light rear filament lighting at two sides even, light color and illumination effect and approach incandescent lamp filament and light color and illumination effect.
In the utility model embodiment, the luminescence chip of a lot of LED can be set at rack surface.
Meanwhile, above-mentioned full angle light-emitting filament can be manufactured by the following method:
Luminescence chip is fixed on and is being provided with the rack surface of loophole, and luminescence chip is welded together by metal wire and pin according to polarity, pin and support are fixed simultaneously;
After being mixed with glue, fluorescent material stirs and vacuumizing and defoaming; Adopt encapsulating plastic packaging mode (also referred to as mol ding encapsulating mode) to be wrapped in rack surface to form phosphor powder layer mixed material.
Wherein, described pin and support are fixedly specially: carry out injection moulding so that support and pin are fixed together by liquid PPA material.
Certainly; the utility model also can have other embodiment; in the situation that not deviating from the utility model spirit and essence thereof; person of ordinary skill in the field is when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of claim of the present utility model.
