Abstract
The power of the lamp can be mounted at any location. The invention comprises a LED light source and a driving power; said LED light source and the driving power are connected via a cable, and can be separately mounted such that the driving power can be mounted at a place easy to keep maintenances.
Description
Technical field
The present invention relates to lighting field, particularly relate to a kind of LED lighting of long-range driving.
Background technology
The high-power LED lighting has begun to apply in places such as road lighting, tunnel illumination, venue illuminations at present, and in the LED lighting, driving power is a chief component, and the quality of LED driving power and life-span directly have influence on the reliably working of LED lighting.But in actual applications, the useful life of led light source is very long, and often be lower than the life-span several times of led light source the useful life of driving power, and the probability of the problem that is out of order is also higher relatively, so just need often maintenance or change driving power, and owing to driving power and led light source are mounted in together at present, general all in overhead very high place, therefore safeguard very inconvenient, especially in places such as road, tunnel, large stadiums, just safeguard to bother more that maintenance cost is very high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of LED lighting of long-range driving, and the driving power of this light fixture can be installed in the optional position.
The technical scheme that technical solution problem of the present invention is adopted is: the LED lighting of long-range driving, comprise led light source and driving power, and described led light source is connected by cable with driving power, and described led light source and driving power adopt the split mode to install.
The invention has the beneficial effects as follows: because led light source and driving power adopt the split mode to install, therefore, driving power can be installed in the optional position, driving power just can be installed in the position of being convenient to safeguard like this, solve more relatively and the problem that driving power is not easy to safeguard of driving power life-span probability shorter than led light source, that break down, reduced the maintenance cost of LED lighting.

Fig. 2 is the connection diagram of embodiments of the invention 1.
Fig. 3 is the schematic diagram of embodiments of the invention 2.
Embodiment
The LED lighting of long-range driving comprises led light source 1 and driving power 2, and described led light source 1 is connected by cable 3 with driving power 2, and described led light source 1 and driving power 2 adopt the split mode to install.
The present invention be actually with led light source 1 and driving power 2 separately certain distance install, driving power 2 is not installed in the shell of led light source 1, the length L of cable 3 of the present invention generally more than or equal to 1 meter less than 80 meters, led light source 1 is installed in the position that needs use, and driving power 2 is installed in the position of being convenient to safeguard.
The above-mentioned position of being convenient to safeguard is meant does not need special equipment as maintenance platform or aerial ladder, just can overhaul or change the position of driving power 2 easily, generally is meant the place that the position is lower.
Led light source 1 of the present invention also can be one group of led light source, and corresponding, driving power 2 also is one group of driving power, cable 3 also is one group of stube cable, the present invention has adopted common positive pole or has been total to the cable multiplex mode of negative pole, can reduce the use length of cable 3 so greatly, has saved cost.
The size of the sectional area A of cable 3 of the present invention is according to the difference of length L and difference, and L is big more, and the sectional area of the cable of then selecting for use is just big more, is used for overcoming the loss of cable resistance.Experiment showed, that the constant current I of led light source 1 of the present invention, the length L of cable and the sectional area A of cable satisfy: 0.072 L* (I/350) 〉=A 〉=0.036L* (I/350), wherein, the unit of A is square millimeter (MM
2), the unit of L is a rice (M), the unit of I is milliampere (MA).According to the concrete environment for use of led light source 1 and driving power 2, select the cable of different length and sectional area for use, reaching best result of use, when the sectional area of cable too hour, total consumption is big, can not light led light source 1; When the sectional area of cable was too big, cost was too high.
Embodiment 1:
As depicted in figs. 1 and 2, be the example that the present invention is used for street lamp.Through the bottom of lamp stand 5, driving power 2 is installed in distant and in lamp stand 5 subaerial places from led light source 1 cable 3, after driving power 2 breaks down, can safeguard and change driving power 2 easily under the centre of street lamp post 5.Driving power 2 is installed on the heating panel 4, ensures the good heat radiating and the useful life of driving power 2.Led light source 1 and driving power 2 couple together by one group of cable 3, and the length of cable 3 does not wait from 4 meters to 80 meters according to the height of street lamp post 5, and the sectional area of cable 3 is at 0.3MM
2More than.Driving power 2 is installed in the bottom of lamp stand 5, greatly facilitates to safeguard and the upgrading replacing, has reduced maintenance cost.
Embodiment 2:
As shown in Figure 3, it is the example that the present invention is used for Tunnel Lamp or venue lamp, Tunnel Lamp and venue illuminator lamp position are generally than higher, and quantity is many, when using traditional light fixture, because the useful life and the reliability of driving power 2 are lower than led light source 1, maintenance cost that causes and maintenance difficulties are all very big.In Fig. 3, led light source 1 is one group of led light source 1, and driving power 2 is then installed concentratedly in an electric control cabinet 6, and every group of driving power 2 all is installed on the power supply heat sinking device.This concentrated driving power mounting means greatly facilitates maintenance work, has reduced maintenance cost.
The present invention has broken the natural mode of conventional lamp, creatively led light source is separated installation with driving power, thereby has solved the problem of the medium-term and long-term puzzlement of real work.Certainly, the above embodiments are instantiation of the present invention, under the situation that does not break away from claim restricted portion of the present invention, can do any change or substitute the mounting means of driving power, arrangement mode that quantity and cable be installed.
