Abstract

The invention discloses a light emitting diode (LED) lamp. The LED lamp comprises a lamp holder and a bulb case, wherein a base is arranged in the bulb case, glass stems are arranged on the base, a supporting frame is arranged at the upper ends of the glass stems, the supporting frame comprises an upper supporting plate and a lower supporting plate, the upper supporting plate and the lower supporting plate are arranged at intervals and in parallel, an upper pad is inlaid in the upper supporting plate, a lower pad is inlaid in the lower supporting plate, the upper supporting plate and the lower supporting plate are connected through stand columns, a plurality of LED light bars are arranged between the upper pad and the lower pad, one end of each LED light bar is connected with the upper pad, and the other end of each LED light bar is connected with the lower pad. According to the LED lamp, a combined structure is adopted, the glass stems are shortened, the supporting frame is arranged at the upper ends of the glass stems, the upper pad is arranged at the upper end of the supporting frame, the lower pad is arranged at the lower end of the supporting frame, the LED light bars are welded between the two pads, the pads are coated with resin cored solder, and an independent lighting body is formed through reflow soldering. The LED lamp has the advantages that the problem of fracture of the stems or pins of the LED light bars is solved and manufacturing and assembling are convenient due to the fact that the supporting frame can be machined independently.

Description

A kind of LED lamp

Technical field

The present invention relates to the LED lighting technical field, particularly a kind of LED lamp.

Background technology

The LED lamp just uses in large-scale promotion at present as a kind of novel high-efficiency and energy-saving light source.Along with development of technology, its light efficiency is also in continuous raising, and new in the market its illuminator of a product of releasing is similar to the incandescent lamp tungsten filament, light efficiency is higher, lighting angle is near incandescent lamp, but its production efficiency is lower, yield rate is low, can't produce in enormous quantities.

Such as conventional products is production technology according to incandescent lamp, on glass stem, insert wire guide, LED lamp bar and seal wire spot welding are linked together,, operate and careless slightlyly will cause stem stem or LED lamp bar pin breakage because glass stem and LED lamp bar all compare fragility.

Summary of the invention

The present invention has overcome above-mentioned the deficiencies in the prior art, and a kind of production efficiency and yield rate of having improved is provided, make product can apply on a large scale and LED lamp integral solder more firm, the LED lamp of long service life.

Technical scheme of the present invention is achieved in that

A kind of LED lamp, comprise lamp holder, cell-shell is provided with base in cell-shell, glass stem is housed on base, be provided with support in the glass stem upper end, described support comprises upper and lower two gripper shoes that spaced and parallel is provided with, and is inlaid with upper and lower two pads on upper and lower two gripper shoes respectively, link to each other by column between the upper and lower gripper shoe, be provided with a plurality of LED lamp bars between upper and lower pad, an end of LED lamp bar links to each other with last pad, and the other end of LED lamp bar links to each other with following pad.

Easy to process for making, layout is more reasonable, as preferably, upper and lower pad is circle, the diameter of last pad is less than the diameter of pad down.

For making firm being fixed on the glass stem of support, as preferably, on the lower supporting plate bottom surface, be provided with attachment cap, described attachment cap is buckled on the glass stem, and lower supporting plate bottom surface and glass stem bonding is fixing.

As preferably, described base integral body is to be rotated a circle around a vertical center axis through center, base lower end by a curve to form, the upper end of base, lower end are respectively equipped with loam cake, lower cover, have a hole in the loam cake center, and glass stem inserts in the described hole.Base is made for the PBT plastic material, base the installation that can make things convenient for glass stem is set, as long as it is inserted in the base.

For increasing whole lighting angle, as preferably, described LED lamp bar is for being obliquely installed, and LED lamp bar is 60～80 degree with respect to the angle that the residing plane of pad down tilts.

As preferably, described support is the clear polycarbonate support.Utilize the plasticity of polycarbonate plastic, can as required support be made different shapes, and it is made transparent, also do not influence illumination.

Adopted the invention has the beneficial effects as follows of technique scheme:

The present invention has adopted fabricated structure, be that glass stem is shortened, and above glass stem, be provided with a support, respectively be provided with a pad in two ends up and down at support, welding LED lamp bar is smeared the tin slurry on pad between two pads, make an independently illuminator by reflow soldering, solved the problem of stem stem or LED lamp bar pin breakage, and support can be processed separately, thereby made things convenient for production, assembling.
