Technical field
The utility model relates to a kind of fluorescent tube, specifically refers to a kind of fluorescent tube being convenient to the LED daylight lamp of installing.
Background technology
Advantages such as volume is little because having for LED daylight lamp, energy-conserving and environment-protective, long service life, noise are little and substitute common fluorescent lamp gradually.The fluorescent tube of existing LED daylight lamp comprises lampshade, heat-dissipation lamp housing, LED luminescence component and respectively with the first end cap, second end cap of a pair pin, wherein first, second end cap be separately fixed at lampshade be connected with heat-dissipation lamp housing after two ends, LED luminescence component and the LED drive circuit of driving LED illuminator work can all be positioned at the space be made up of lampshade and heat-dissipation lamp housing.
The comparatively early fluorescent tube of the LED daylight lamp of design, the end cap at its two ends is fixedly connected respectively by screw and heat-dissipation lamp housing, once installation, lampshade, heat-dissipation lamp housing and LED illuminator just can not rotate adjustment as required.What the LED illuminator in LED daylight lamp adopted is SMD lamp pearl, and its luminescence has certain orientation, therefore adopts traditional end cap, LED daylight lamp will be made to also exist and irradiate blind area.And the distributing position installing the pin holes of occasion is at present also different, therefore the structure that this end cap is fixedly connected with lamp housing is also not easy to install.
Can rotate as required after mounting to make LED daylight lamp, light is made to expose to effective coverage, existing people have designed the adjustable LED lamp tube of irradiating angle, as " LED lamp adjustable in angle pipe " that Chinese patent application publication No. is CN103123055A, plug in this fluorescent tube comprises plug set casing and plug tumbler, this plug tumbler can do one direction relative to plug set casing and rotate, the plug tumbler of plug part is rotated lightly during use, can adjust the lighting angle of fluorescent tube, thus make fluorescent tube irradiating angle reach optimization, such structure is also convenient to install simultaneously.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, provides a kind of LED lamp tube being convenient to install that can adjust the lighting angle of fluorescent tube equally.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of fluorescent tube being convenient to install, include lampshade, heat-dissipation lamp housing, LED luminescence component, LED drive circuit and respectively with the first end cap of a pair lamp base, second end cap, this first end cap, second end cap be connected to described lampshade be connected with heat-dissipation lamp housing after two ends, described LED luminescence component and LED drive circuit are installed on heat-dissipation lamp housing, described LED drive circuit is connected with lamp base by power line, it is characterized in that: the first described end cap, second end cap includes the fixed cap that is connected with fluorescent tube and the rotatable cover with lamp base, this rotatable cover inserting is connected on fixed cap and also can rotates relative to fixed cap, the outer face of described fixed cap is provided with the ring part that an internal perisporium has limited impression, be provided with a keeper be connected with rotatable cover in this ring part rotationally, the outer peripheral face of this keeper have the double wedge that at least one and described limited impression match.
As further improvement of the utility model, the inner face of described rotatable cover forms at least one locating dowel of arranging towards keeper, corresponding, the upper surface of described keeper is formed with the locating slot inserted for locating dowel.Rotatable cover is connected with keeper by said structure, when rotary motion lid, locating dowel to be stuck in locating slot thus to drive keeper to rotate, often rotate an angle, namely double wedge on locating dowel outer peripheral face is stuck in the corresponding limited impression of ring part, thus carry out spacing to each rotational angle, prevent rotatable cover from arbitrarily rotating under non-artificial rotation.
Further, described ring part has the through hole that power supply source line passes, corresponding, the inner face of described rotatable cover is formed with the joint pin that can insert in through hole, the end of this joint pin is formed with outside card base, the internal perisporium of described through hole has the convex edge matched with card base.After above-mentioned joint pin and convex edge are blocked mutually, do not affect rotatable cover and rotate relative to fixed cap, but the assembling that the inserting-assembling type between rotatable cover with fixed cap is connected for fluorescent tube is provided convenience, depart from fixed cap to prevent rotatable cover.
In above-mentioned each scheme, described double wedge has two and be symmetrically distributed on the outer peripheral face of keeper respectively, and offers on the keeper of double wedge along keeper elongated hole circumferentially.Arrange two symmetrical double wedges and can make keeper uniform force in rotation process, the setting of elongated hole then can reduce the difficulty that double wedge rotates between limited impression, is more convenient to user and regulates.
As preferably, the edge of described through hole stretches out and is formed as an extension, and described keeper is sheathed on the periphery of this extension.This structure is set to increase the stability of keeper motion, prevents keeper from affecting use at ring part bias internal.
In above-mentioned each preferred version, the outer face of described fixed cap is provided with a limited post near ring part, corresponding, the internal perisporium of described rotatable cover has at least one can play barrier effect raised line to limited post, this raised line is preferably two and is symmetrically distributed on the internal perisporium of rotatable cover.The angle that said structure makes rotatable cover rotate along a direction more than 180 °, can not be rotated excessively in case spline moves cover rim direction and causes fluorescent tube internal power cord to damage.
Preferably, described limited impression has several, and on the interconnective internal perisporium being arranged in described ring part of each limited impression.Each limited impression determines an angle, arranges several interconnective limited impressions and can provide very thin low-angle adjustment for fluorescent tube, rotated multiple limited impression and then can carry out wide-angle adjustment, and this provides a great convenience for user.
Preferably, described joint pin inner hollow and there is near the both sides of lamp base opening respectively that hold power line.The assembly space between rotatable cover and fixed cap has effectively been saved in arranging of this structure, makes the structure of end cap compacter, reasonable.
Compared with prior art, the utility model has the advantage of and end cap is set to fixed cap and rotatable cover, and fixed cap and rotatable cover are carried out inserting-assembling type be connected, easy to connect, be convenient to install; The outer face of fixed cap is provided with the ring part with limited impression, and in ring part, be provided with the keeper be connected with rotatable cover, after fluorescent tube has assembled, user can rotary motion lid as required, the keeper be connected with rotatable cover rotates thereupon, and the double wedge of keeper outer peripheral face snaps in limited impression and can carry out spacing to respective angles, thus achieve the adjustment to lamp luminescence angle, swift to operate, easy to use.
