High lamp philips led to absorb dome light price is not ground wire is there a problem

High pressure sodium lamp and metal halide lamp based on the strong penetration ability of the fog and the advantages of the ultra high luminous flux favor by lighting area, even in recent years, the LED energy-saving products in the lighting industry has the potential of a presumptuous guest usurps the host's role, but it is hard to replace sodium lamp or metal halide lamp, not



high pressure sodium lamp and metal halide lamp Metal halide lamp by metal vapor ( For example, mercury) And halide ( Such as dysprosium, sodium, thallium, indium and other elements of the halide) Decomposition of a mixture of radiation and the glowing gas discharge lamp. 】 Relying on its own strong penetration ability of the fog and the advantages of the ultra high luminous flux by lighting field, even in recent years, the LED energy-saving products in the lighting industry has the potential of a presumptuous guest usurps the host's role, but it is hard to replace sodium lamp or metal halide lamp ( Metal halide lamp ( Metal Halide Lamp） Is ac power, working in mercury and rare metal halide mixture vapor arc discharge in glowing discharge lamp, metal halide lamp is on the basis of high pressure mercury lamp add various metal halide made of the third generation light source. 】 , can't deny the advantages of these two kinds of lamps and lanterns does have its existence value. The most commonly used to sodium lamp or metal halide lamp power is 250 w, 400 w, 1000 w, the lamps and lanterns of the power configuration is among the highest in the frequency on the light pole, the reason is very simple, because of its high brightness, illumination, and has a certain ability to penetrate the fog, on either side of the road lighting installation sodium lamp or metal halide lamp is good. So here we have to come up with a question, that is installed on the light pole cast light lamps will be struck by lightning solar garden lights? When it comes to lightning 【 Is accompanied by lightning of the thunder and lightning and thunder of a discharge phenomenon. 】 Hit on the phenomenon, let a person have to LED lamps and lanterns of lamps and lanterns, because the LED lamps and lanterns fruit peels was killed by a bolt of lightning strike bad examples.

high pressure sodium lamp any objects are the same, want to bad, or was killed by a bolt of lightning strike is the only way to the ground, LED lamps and lanterns is very easy to hit the bad is because of the constant current source inside the lamp without grounding, if don't want to say, caused by damage of the LED lamps and lanterns is natural lightning is inevitable, that also have to admit that it has been for installation personnel in the installation of lamps and lanterns of lightning damage lamps and lanterns has created favorable conditions. The overall structure and the luminescent principle of LED lamps and lanterns with high pressure sodium lamp are completely different, that their lightning-proof ability will be the same? The answer is yes, of course not, high pressure sodium lamp or metal halide lamp was killed by a bolt of lightning strike bad case is annals are numbered. After open the sodium lamp cover can be very intuitive see, terminal has a total of three holes, left and right sides of the zero line and the line of fire, in the middle of the ground, the terminal service terminal can clearly see the ground after the card is with the lamp shell is a body, which is as long as the install lamps and lanterns on the street lamp or light, the light itself is grounded, the equivalent of lamps and lanterns is grounded, so even if the lamps and lanterns in the ground terminal is not grounded is doesn't matter, all may not be lightning strike. Light, but not all of the metal halide lamp and sodium lamp project-light lamp do not need ground under any circumstances, use a separate grounding line depends on the fixed carrier, if it is installed on the steel bar, that's not ground wire is no problem, but if installed on the high walls or concrete pole is another matter, because the object is not a good electrical conductor, installed in the position to the lamps and lanterns to the ground terminal derivation from the underground to safety. So everything should according to the actual.
