Abstract

The utility model discloses an LED filament including an electrode support and a substrate which are connected with each other at the ends in an overlapping manner, a plurality of LED chips are fixed and electrically connected on the substrate, and clamping plates are fixed at the two side edges of the mutually overlapping sections of the electrode support and the substrate to coat the two side edges of the contact surfaces of the electrode support and the substrate. By adopting such a structure, the clamping plates take a reinforcing effect on the connecting section of the electrode support and the substrate, so that the firm electric connection can be guaranteed.

Description

A kind of LED filament

Technical field

The utility model relates to a kind of LED lamp, espespecially a kind of LED filament.

Background technology

LED filament lamp is a kind of light fixture of imitated incandescent lamp, and it replaces the filament of conventional incandescent with LED filament.This novel LED lamp, just can reach lighting angle and the illuminating area identical with incandescent lamp without installing lens additional, and the power consumption again with LED lamp is low, the effect such as the life-span is high, environmental protection.

As shown in Figure 1, the filament support 2 that mainly comprises LED filament 1, is electrically connected with internal circuit element in order to fix and to realize filament, is also covered with transparent glass cell-shell 3 in the outside of LED filament 1 to the structure of LED filament lamp.This LED filament lamp appearance and incandescent lamp are similar, just both filamentray structure differences.

As shown in Figure 2, it comprises electrode suppor 11 and substrate 12 to the general structure of LED filament 1, fixes and be electrically connected with some LED chips 13 on this substrate 12, interfixes and realize and being electrically connected between this electrode suppor 11 and substrate 12.1, this LED filament is fixed on by its electrode suppor 11 on the filament support 2 of light fixture.Being connected between the electric machine support 11 of existing LED filament and substrate 12 is by simple bonding mode, and the end specifically both being connected is mutually stacked a bit of, then with (silver) glue bond.But but there is following shortcoming in the LED filament of this structure: cell-shell 3 is in the time of sealing, sealing temperature is far away higher than the curing temperature of (silver) glue, high temperature when cell-shell sealing may cause (silver) glue generation chemical reaction liquefaction, make between electrode suppor 11 and substrate 12, to occur that void is sticky, even come off, and then cause LED filament to lose efficacy; In addition, when occurring that when empty sticky, possible LED filament still can normally be lighted, but vibration in the assembling of LED filament lamp finished product or transportation may make rosin joint position depart from, and causes the inefficacy of LED lamp finished product.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of more certain LED filament of electrical connection that makes.

For solving the problems of the technologies described above, technical solution of the present utility model is:

A kind of LED filament, comprises that end overlaps electrode suppor and the substrate of connection mutually, fixes and be electrically connected with some LED chips on this substrate, and the mutual lap segment dual-side of this electrode suppor and substrate is fixed with clamp the dual-side of both contact-making surfaces is wrapped up therein.

Described clamp is one-body molded on described electrode suppor, its side from electrode suppor first to substrate one lateral buckling again bending to the inside form L shaped, thereby the end of this substrate is fixed between two L shaped clamps and electrode suppor main body.

The contact-making surface of described electrode suppor and the mutual lap segment of substrate carries out bonding with glue.

Adopt after such scheme, because the utility model has been fixed clamp at the electrode suppor of LED filament and the lap segment dual-side of substrate, on the one hand both linkage sections are reinforced, guarantee that electrical connection is more certain, in the contact-making surface both sides of electrode suppor and substrate can being wrapped on the other hand, although the two ends of contact-making surface are still exposed in air, but the temperatures involved while being subject to cell-shell sealing will greatly reduce, therefore can effectively prevent because of the elargol sticky phenomenon of the void that causes that liquefies the break-off of avoiding filament to lose efficacy and causing because of vibration.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

What the utility model disclosed is a kind of LED filament, as shown in Figures 3 to 5, is preferred embodiment of the present utility model.Described LED filament 1 comprises that end overlaps electrode suppor 11 and the substrate 12 of connection mutually, on this substrate 12, fix and be electrically connected with some LED chips 13, this electrode suppor 11 is fixed with clamp 111 with the mutual lap segment dual-side of substrate 12 dual-side of both contact-making surfaces is wrapped up therein.

This clamp 111 can be one-body molded on described electrode suppor 11, its side from electrode suppor 11 first to substrate one lateral buckling again bending to the inside form L shaped, thereby the end of this substrate 12 is fixed between two L shaped clamps 111 and electrode suppor 11 main bodys.

In order to make connection more reliable, described electrode suppor 11 carries out bonding with the contact-making surface of substrate 12 mutual lap segments with glue.

After having fixed clamp 111, clamp 111 can play the effect of reinforcing to electrode suppor 11 and the linkage section of substrate 12, can guarantee that electrical connection is more certain.On the other hand, clamp 11 can also be in contact with one another electrode suppor 11 and substrate 12 both sides of face and wrap up therein, although the two ends of contact-making surface are still exposed in air, but the temperatures involved while being subject to cell-shell sealing will greatly reduce, therefore can effectively prevent because of the elargol sticky phenomenon of the void that causes that liquefies the break-off of avoiding filament to lose efficacy and causing because of vibration.

The above, be only preferred embodiment of the present utility model, is not used for limiting the scope that the utility model is implemented.Therefore variation or the modification in every case done according to claim of the present utility model and specification, within all should belonging to the scope that the utility model patent contains.
