Abstract

A rotary lamp cap of a reflection-type lamp bulb comprises a porcelain piece provided with an electrode tip, and a lamp cap body. The rotary lamp cap of the reflection-type lamp bulb further comprises a shell which is connected in the lamp cap body in a sleeved mode. The porcelain piece is matched with the inner wall of the shell. The lamp cap body, the shell and the porcelain piece are connected to form a whole through elastic fixing pieces which are mounted on the porcelain piece. The shell can rotate in the lamp cap body. The rotary lamp cap is simple in structure and has few parts. Due to the fact that the lamp cap body and the shell are both stamping pipe fittings, the rotary lamp cap is easy to machine and manufacture and low in cost. Moreover, tools are not needed for assembly and disassembly of the rotary lamp cap, the position of the reflection-type lamp bulb can be rotated, adjusted and controlled arbitrarily within the range of 360 degrees, after the position of the reflection-type lamp bulb is well adjusted, the rotary lamp cap can also be rotated so that the whole rotary lamp cap is fixed and locked, and therefore the rotary lamp cap can no longer rotate and is safe and reliable to use. When the rotary lamp cap of the reflection-type lamp bulb is used, the illumination direction of the reflection-type lamp bulb can be adjusted conveniently and quickly to face the direction required by a user in a centralized mode just in the mode that the reflection-type lamp bulb is rotated with a hand, the rotary lamp cap can be in common use with an existing lamp cap in size, specification and performance, the user can use the rotary lamp cap directly without the need of adding any auxiliary or alteration, and therefore the rotary lamp cap of the reflection-type lamp bulb is convenient to use.

Description

The rotation lamp holder of reflection-type bulb

Technical field

The utility model relates to a kind of and industry is connected supporting lamp holder with modern agriculture factory used irradiation bulb, particularly a kind of rotation lamp holder that can effectively fast adjust the reflection-type bulb of light direction.

Background technology

China Patent No. 201220014617.5 " ultraphotic effect spectrum lamp ", " 201220015144.0 superbright spectrum lamp ", it is logical strong just to provide a kind of width of cloth to penetrate light, and spectral content is abundant, the luminous efficiency height, can be widely used in the irradiation of high-power plant and use, and the function of light harvesting source and reflector is in one, effective light extraction efficiency reaches more than 90%, than using light fixture, the end lamp of filming to exceed a lot, be energy-conservationly can reduce cost of investment again, go back little, in light weight, the easy installation of volume, easy to use, effective.

But because of the spectrum lamp design feature, namely first inwall at fluorescent tube scribbles reflective membrane, be used for replacing reflector or lampshade, the two edges of filming during use must remain on the horizontal level and the parallel coincidence of the center line of lamp, the light that bulb could be sent focuses on us fully and wishes the zone illuminated, illumination zone maximum like this, service efficiency is best, but in real work because of all multifactor, the bulb that is difficult to accomplish to be tightened keeps the interior reflective membrane of bulb all the time at horizontal level again, and towards our needed direction.Easily cracked as if lamp socket that bulb is overwinded, if it is easily loosening to revolve lamp holder too loose bottom, produced hidden dangers such as creepage, arcing, sparking by loose contact, can not regulate because of lamp holder, bulb position and can't satisfy the many-sided demand of user, simultaneously can not reach best result of use, the relevant adjustable rotation lamp holder of lamp holder patent is arisen at the historic moment for this reason.

China Patent No. 201120212031.5 " 180 degree revolving light header structures of LED fluorescent tube ", number of patent application 201110268488.2 " rotatable lamp holder ", it mainly is to solve when being used as fluorescent lamp by LED, the one side of LED light-emitting component is towards the irradiated direction of needs, because fluorescent-lamp tube can not be regulated rotation, the one side that causes the LED light-emitting component of circuit board, sometimes not just will influence illuminating effect towards illuminated direction, need adopt above-mentioned rotation lamp holder to solve this problem, but above-mentioned rotation lamp holder all is the rotation lamp holder of plug-in type for this reason.

Summary of the invention

Technical problem to be solved in the utility model is: the rotation lamp holder that a kind of reflection-type bulb is provided, its simple in structure, easy making processing, cost are low, be connected supporting use with the reflection-type bulb of all size, just can regulate, control effective light direction as long as rotate bulb rotation lamp holder, the light that the reflection-type bulb is sent focuses on us and wishes the zone illuminated, satisfy the many-sided demand of user, make bulb light extraction efficiency maximum, brightness the highest.

The technical scheme in the invention for solving the above technical problem is: the rotation lamp holder of reflection-type bulb, comprise the porcelain spare and the lamp holder that have electrode tip, also comprise and be socketed with housing in the lamp holder, and porcelain spare cooperates with inner walls, by the flexible fastening piece that is installed on the porcelain spare, lamp holder, housing, porcelain spare are linked into an integrated entity, and described housing can rotate in lamp holder.

Compared with prior art, advantage of the present utility model is: this revolving light header structure is simple, part is few, lamp holder, housing, porcelain spare three parts are only arranged, and lamp holder, housing all are the punching press pipe fittings, easily processing, making, cost are low, and assembling, dismounting do not need instrument, only just be fixed into rotating integral body with a flexible fastening piece, and can in 360 degree scopes, rotate the position of regulating bulb arbitrarily, after adjust the bulb position, also rotatable lamp holder can not rotate whole rotation lamp holder fixing and locking again, uses safety, reliable.Need only with hand during use and rotate the illumination direction that bulb just can be adjusted bulb easily and efficiently, make the direction that bright dipping is concentrated to be needed towards us, size, specification, performance and the existing lamp holder of this rotation lamp holder are general, the user need not do any change or increase auxiliary just can directly use, and is easy to use.
