Abstract

The utility model discloses a rotating lamp cap for an LED (Light Emitting Diode) tube. The rotating lamp cap comprises a rotating seat and a fixed seat which are axially and fixedly connected with each other and can rotate relatively; ring gears are arranged at one side of the fixed seat opposite to the rotating seat, correspondingly, a plurality of spring laminations are arranged at one side of the rotating seat opposite to the fixed seat; and salient points clamped into the ring gears are arranged at the free end of each spring lamination. The rotating lamp cap has a simple structure; after the LED tube is installed through the rotating lamp cap, the illuminating angle of the LED tube can be adjusted at any time; the rotating lamp cap is convenient to use and has stronger practical applicability and is especially suitable for places having the requirement on varying illuminating angles of the LED tube at any time.

Description

A kind of LED fluorescent tube is with rotating lamp holder

Technical field

The utility model belongs to light fixture mounting technology field, specifically relates to a kind of LED fluorescent tube with rotating lamp holder.

Background technology

LED (Light Emitting Diode) is a light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity, so LED uses more and more widely in the lighting apparatus field.The LED light fixture with of fine quality, durable, energy-conservation be main feature, and its crevice projection angle adjustable range is big, the brightness of 15W is equivalent to common 40W fluorescent lamp, high temperature resistance, moistureproof and waterproof, anticreep, be subjected to developer's concern at present deeply.

Yet after the at present used LED lamp holder installation, the irradiating angle of the light fixture on it is changeless, the occasion that this lamp socket is often regulated LED light fixture irradiating angle for needs needs frequent dismounting lamp socket to install, can reduce the service life of lamp socket so greatly, bring very big inconvenience also for the use of LED light fixture.

Summary of the invention

The utility model provides a kind of LED fluorescent tube with rotating lamp holder, and this holder structure is simple, and after using this lamp holder with the installation of LED fluorescent tube, the irradiating angle of LED fluorescent tube can conveniently be regulated, and is easy to use.

A kind of LED fluorescent tube is with rotating lamp holder, comprise that axial restraint connects and relatively turnable rotation seat and holder, described holder is provided with ring gear over against rotation seat one side, and corresponding rotation seat is provided with some shell fragments over against holder one side, and the shell fragment free end is provided with the salient point that snaps in ring gear.

For realizing that rotation seat is connected with the holder axial restraint and can relatively rotates, described rotation seat center is provided with fixing hole, the holder center is provided with the rotating shaft of passing fixing hole of hollow, and the end end that rotation seat is passed in rotating shaft is provided with the bulge loop that is used to limit the rotation seat axially-movable.For ease of assembling, an end setting that can bulge loop be set in described rotating shaft from this end to the axially extended notch of the other end; The setting of notch makes to be demountable structure between rotation seat and the holder, has made things convenient for the replacing of holder or rotation seat; Quantity that notch is provided with and width size are generally determined according to actual needs, are guaranteeing to make things convenient under the prerequisite of holder dismounting, and notch is unsuitable excessive, and the excessive intensity of rotating shaft that causes easily reduces.

For preventing that fixing hole from causing can't being connected between rotation seat and the holder because of wearing and tearing, can extend the reinforcing sleeve that cooperate with rotating shaft to form with described fixing hole edge to holder.

In the actual use, the angle that light fixture need rotate is general all in 180 degree, for guarantee that holder can rotate freely along rotation seat in 180 degree, can between described ring gear and rotating shaft, cannelure be set, the outer shroud side face of cannelure is provided with two blocks, simultaneously over against a side of holder a limited block that cooperates with block is set at described rotation seat.

For further strengthening the intensity of rotating shaft, can away from bulge loop one end two crossed reinforced pieces be set at described rotating shaft inner chamber.

LED fluorescent tube of the present utility model is with the rotation lamp holder, and is simple in structure, and after using this lamp socket with the installation of LED fluorescent tube, the irradiating angle of LED fluorescent tube can be regulated at any time, easy to use, be particularly useful for occasion that LED fluorescent tube irradiating angle needs are changed at any time, practicality is stronger.

The specific embodiment

Shown in Fig. 1～6, a kind of LED fluorescent tube is with rotating lamp holder, comprise that axial restraint connects and relatively turnable rotation seat 1 and holder 2, holder 2 is provided with ring gear 3 over against rotation seat 1 one sides, corresponding rotation seat 1 is provided with four shell fragments 4 over against holder 2 one sides, and shell fragment 4 free ends are provided with the salient point that snaps in ring gear 3.

General and the lamp holder mount pad of rotation seat 1 interfixes; Rotation seat 1 is provided with two installing holes 14, is used for fixing with the LED fluorescent tube; For reducing the cost of manufacture of rotation seat 1, rotation seat 1 is provided with 3 material reducing holes 15.Rotation seat 1 center is provided with fixing hole 5.Fixing hole 5 edges extend to form reinforcing sleeve 9 to holder 2, to strengthen the scuff resistance of fixing hole 5.Rotation seat 1 over against a side of holder 2 be provided with reinforcing sleeve 9 near limited block 12.

The through hole that holder 2 is fixed with two locking pins 16 and aligns mutually with installing hole 14 on the rotation seat 1 away from a side of rotation seat.Holder 2 centers are provided with the rotating shaft of passing fixing hole 56 of hollow, and the end end that rotation seat 1 is passed in rotating shaft 6 is provided with the bulge loop 7 that is used to limit rotation seat 1 axially-movable.The end that rotating shaft 6 is provided with bulge loop 7 is provided with from this end to the axially extended notch 8 of the other end.Rotating shaft 6 inner chambers are provided with two crossed reinforced pieces 13 away from bulge loop 7 one ends, to strengthen the intensity of rotating shaft 6.Be provided with cannelure 10 between ring gear 3 and the rotating shaft 6, the outer shroud side face of cannelure 10 is provided with two blocks 11, matches with limited block 12 on the rotation seat 1 and realizes that holder 2 relatively rotates seat 1 rotation in 180 degree.

LED fluorescent tube in the present embodiment with rotation lamp holder actual installation process is: at first the rotating shaft 6 with holder 2 snaps onto in the fixing hole 5 of rotation seat 1, and the through hole that utilizes screw to pass holder 2 is then fixed rotation seat 1 and got final product with the LED fluorescent tube.LED fluorescent tube in the present embodiment is used in the actual use of rotation lamp holder, adjusts the setting angle of LED fluorescent tube if desired, only needs that rotation seat 1 is turned to the setting angle that needs and gets final product, and the double wedge on the ring gear 3 snaps onto on the shell fragment 4 at this moment, stops operating.
