Description

Anti-tilt LED lamp

Technical Field

The utility model belongs to the technical field of B35 series LED lamp technique and specifically relates to an anti-tilt LED lamp.

Background

The LED lamp described herein is for the B35 series, which uses a 38MM light bar for a long period of time, and has only a power of 3 to 4 watts and a luminous flux of 300 to 400 LM. It can be said that it is more difficult to produce a lamp of higher luminous flux using a B35 envelope of smaller volume, and the foreign market demands 800LM LED filament lamps made from B35 envelopes. In addition, the B35 candle bulb in the prior art has the problem of B35 askew core.

SUMMERY OF THE UTILITY MODEL

To the above problem, an object of the utility model is to provide a prevent LED lamp of slope, the utility model discloses a technical scheme as follows:

an anti-tilt LED lamp comprises a lamp holder, a glass bulb shell connected with the lamp holder, a core column arranged in the glass bulb shell and connected with the lamp holder, and a lamp filament arranged on the core column; the core column comprises a horn part fixed on the lamp holder, an exhaust hole formed in the horn part, two outer leads penetrating into the horn part from bottom to top, a Demet wire arranged in the horn part and connected with the outer leads in a one-to-one correspondence manner, an inner guide wire with one end connected with the Demet wire and the other end connected with the lower part of the filament, a glass solid core arranged in the center of the top of the horn part, an exhaust pipe penetrating into the horn part from bottom to top and connected with the exhaust hole, and an alloy wire arranged at the top of the glass solid core and connected with the upper part of the filament;

the height of horn portion is 22mm, and the height of glass solid core is 52 mm.

Further, the upper portion of the filament is in contact with the inner wall of the glass bulb.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model discloses an original B35 type glass bulb to increase the length of lamp strip to 50MM by 38MM, stem support after the improvement just can use 50 MM's lamp strip production luminous flux to reach 800LM, and power reaches the high luminous flux B35 candle type LED filament lamp more than 7 watts. In addition, the solid core is changed from 40 to 52, and the top of the stem welded with the light bar is just fixed on the inner wall of the B35 glass shell due to the increase of the solid core size of the stem support, so that the problem that the B35 of the B35 candle bulb is askew in core can be solved. Because the sealed bulb is filled with helium gas, the heat generated by the filament is transferred to the bulb. To sum up, the utility model has the advantages of simple structure, fixed reliable, high luminous flux have very high practical value and spreading value in B35 series LED lamp technical field.

Detailed Description

To make the objectives, technical solutions and advantages of the present application more clear, the present invention will be further described with reference to the accompanying drawings and examples, and embodiments of the present invention include, but are not limited to, the following examples. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Examples

As shown in fig. 1 to 2, the present embodiment provides an anti-tilt LED lamp. In the present embodiment, the terms of orientation such as "bottom", "top", "peripheral edge", "center", and the like are explained based on the drawings.

In the embodiment, the anti-tilt LED lamp comprises a lamp cap 1, a glass bulb 3 connected to the lamp cap 1, a stem 2 disposed in the glass bulb 3 and connected to the lamp cap 1, and a filament 4 disposed on the stem 2. Wherein, stem 2 is again including fixing the horn part 23 on lamp holder 1, sets up exhaust hole 28 on horn part 23, follows supreme two outer conductors 22 that penetrate in horn part 23 down, arranges in horn part 23, and the dumet wire 24 of being connected with outer conductor 22 one-to-one, one end is connected with dumet wire 24, and the other end and the interior seal wire 25 of filament 4 sub-unit connection, sets up the glass solid core 26 at the top central authorities of horn part 23, follow supreme blast pipe 21 that penetrates in horn part 23, and be connected with exhaust hole 28 down to and set up at the top of glass solid core 26, and the alloy silk 27 of being connected with the upper portion of filament 4. In the present embodiment, the height of the trumpet portion 23 is increased from 17mm to 22mm, and the height of the solid glass core 26 is increased from 40mm to 52 mm. In this way, the upper part of the filament 4 is just in contact with the inner wall of the glass bulb 3. As the sealed glass bulb 3 is filled with helium, heat generated by the filament 4 is transferred to the glass bulb through the helium, and the applicant can know that the surface temperature of the glass bulb of the improved LED lamp is 40-45 ℃ through measuring a large amount of glass bulb temperature, so that the use requirement is met.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and are not limitations on the protection scope of the present invention, but all the changes made by adopting the design principle of the present invention and performing non-creative work on this basis shall fall within the protection scope of the present invention.
