Technical field
The utility model relates to lighting technical field, is a kind of conversion equipment that is applied in the T5 light fixture on the emergency light specifically.
Background technology
Low-voltage fluorescent lamp used in everyday is called the low pressure mercury vapor fluorescent lamps again, is be most widely used in present all types of gas-discharge lamp a kind of, and it all is widely used as public places such as domestic lighting or market, theaters at room lighting.At present, the T8 fluorescent lamp is to use one of electric light source comparatively widely, but shortcoming such as the T8 fluorescent tube of conventional art exists that power consumption is big, light efficiency is low, stroboscopic is arranged, colour rendering difference.
In recent years, advantage such as T5 light fixture and technology thereof have obtained faster development, and its colour rendering is good, luminous efficiency is high, low in energy consumption is liked by users deeply.But because general conventional lamp can not directly install the T5 fluorescent tube, adorn new T5 light fixture, just need expend great amount of manpower and cost if original conventional lamp all dismantled.In order to eliminate the restriction of this situation, multiple fluorescent tube conversion support or adapter have appearred on the market, the T5 fluorescent tube can be installed in earlier on conversion support or the adapter, again conversion support or adapter are installed on the lamp socket of original T8 fluorescent tube, do not need to dismantle the lamp socket of original T8 fluorescent tube.
Common T5 light fixture conversion support uses after replacing the T8 fluorescent tube on the emergency light, under the normal situation of civil power, and the energy operate as normal, but under power-off condition, but can't normally light fluorescent tube, cause emergency light normally to use.Having the special T8 of some circuit structures to change T5 light fixture crossover sub at present can be under situation about having a power failure, normally light the T5 fluorescent tube on the emergency light, this series products is made of the crossover sub of two separation, wherein major joint inside is equipped with a circuit ballast circuit board, there are two defectives in it: at first, the inner space of major joint is limited, makes the poor radiation of electronic ballast circuit, life-span lack; Secondly also be because the inside of major joint is provided with circuit board, and diameter group is many greatly mutually with former T8 fluorescent tube, cause and to install owing to the space is limited in a lot of emergency lights.
The utility model content
Task of the present utility model is to solve a prior art difficult problem, and a kind of T5 light fixture conversion support that can use on the T8 emergency light is provided.
Technological means
The utility model discloses a kind of T5 light fixture conversion support that is used on the emergency light, comprise a support cavity, be installed in the main support joint and the assistant support joint at support cavity two ends and be arranged on electronic ballast circuit in the support cavity respectively, wherein the main support joint comprises T8 tube plug and T5 lamp tube socket, two inserting columns of T8 tube plug are connected with zero line with live wire respectively, and be electrically connected with the feeder ear of described electronic ballast circuit respectively, the output of electronic ballast circuit is electrically connected with the T5 lamp tube socket; The assistant support joint comprises T8 tube plug and T5 lamp tube socket, and the T8 tube plug is electrically connected with the T5 lamp tube socket.
A joint of electronic ballast circuit output is connected electrically in a jack of the T5 lamp socket of main support joint, or is connected electrically in two jacks of the T5 lamp tube socket of main support joint simultaneously; Or two joints of electronic ballast circuit output are connected electrically in the same jack of the T5 lamp tube socket of main support joint simultaneously, or are connected electrically in two jacks of the T5 lamp tube socket of main support joint respectively.
Be arranged on short circuit between two jacks of the T5 lamp tube socket on the main support joint.
Be arranged on short circuit between two jacks of the T5 lamp tube socket on the assistant support joint, and be arranged on short circuit between two inserting columns of the T8 tube plug on the assistant support joint.
Electronic ballast circuit is made of discrete component.
The conversion support of T5 light fixture also is provided with connector, and one of them inserting column of the T8 lamp tube socket on the main support joint is connected by connector with the assistant support joint.
Connector comprises shell and two metal pins, is connected by lead, fuse or resistance between two metal pins, and the structure of the installation position of the starter that the profile of shell and former T8 light fixture are used is complementary.
Beneficial effect
The utility model has been made further improvement to line connection on the basis of existing technology: at first on the basis that does not change primary inductance type T8 emergency luminaire internal wiring and structure, can both operate as normal under the situation that guarantees that light fixture is normal at civil power and have a power failure, this point is the function that most of in the market T5 light fixture conversion equipments can't be realized, the T8 fluorescent tube is replaced by more energy-conservation T5 fluorescent tube, has obvious energy-saving effect; Secondly the utility model is simple in structure, easy for installation, also can not be restricted because of the size in former T8 light fixture space in use, and thermal diffusivity of the present utility model is good, cost is low, reliability is high, the life-span is long.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a mounting structure schematic diagram of the present utility model;
Fig. 3 is a circuit connecting relation schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises support cavity 3, is installed in the main support joint 1 and the assistant support joint 2 at support cavity two ends, and be arranged on electronic ballast circuit 4 in the support cavity, wherein the main support joint comprises T8 tube plug 11 and T5 lamp tube socket 12, the assistant support joint comprises T8 tube plug 21 and T5 lamp tube socket 22, and the annexation of each parts as shown in Figure 3.
The T8 tube plug 21 of assistant support joint is electrically connected with the T5 lamp tube socket 22 of assistant support joint, also multiple connected mode can be arranged herein, purpose all is to want the electromotive force of two inserting columns of T8 tube plug to equate with the electromotive force of two jacks of T5 lamp tube socket, best connected mode is two inserting column short circuits with the T8 tube plug, with two jack short circuits of T5 lamp tube socket, and then both are directly linked together with lead.
The power supply of emergency light is made up of civil power and reserve battery two parts, and both are the power supply of T8 light fixture by controller, civil power just often, reserve battery is in charged state; During mains failure, it is the emergency light power supply that the direct current of reserve battery output is converted into higher-order of oscillation electric current by controller.Common T8 changes the T5 support to be used on emergency light, civil power just often can use, during mains failure, the high frequency voltage that controller produces is carried in the power input of electric ballast earlier, be the T5 lamp tube power supply by electric ballast again, because the input power supply of electric ballast is not the 50Hz alternating voltage at this moment, but high frequency voltage, the T5 fluorescent tube makes that electric ballast can't operate as normal, so can't normally be lighted.The disclosed T5 light fixture of the utility model conversion support, just often can use at civil power, when mains failure, high frequency voltage is carried in the two ends of conversion support, because the T8 tube plug of assistant support joint is electrically connected with the T5 lamp tube socket of assistant support joint, and the electronic ballast circuit of this moment only is equivalent to the effect of lead, the T8 tube plug of main support joint is equivalent to directly be electrically connected with the T5 lamp tube socket, so high frequency voltage is equal to and directly is carried in the T5 lamp tube ends and makes it still can normally light.
