G4 G9 LED Difference - Knowledge - Yueqing Lapu Lighting Co.,Ltd

The era represented by the G4/G9 lamp beads is exactly the era in which we are fighting today. People are constantly seeking breakthroughs in lighting fixtures, from incandescent lamps to fluorescent lamps to g4/g9, constantly providing us with optimal convenience. .

First of all, to be precise, G4 and G9 refer to the type of pins of different types of light bulbs (lamp beads). G is a lamp base representing two or more pins, and this light bulb is used to refer to a light bulb. The type of pin; the following 4 or 9 or 5.3, 6.35, etc. refer to the distance between the center points of the pins. The standard method uses the caliper to measure the inner distance and the outer distance of the two pins and then divides them by 2 Yes, a simple amount of casually used what ruler than the center point of the two feet about to come out. 4mm and 9mm far from each other, just measure can know.

2, for the current crystal lamps are mostly used G4 or G9, these two differences are very obvious, the most fundamental difference is that G4 can only do low voltage, because the distance of the pins is too close, so if your light is G4 Then, there must be a transformer in the ceiling of the lamp! And now the G9 only has to do high pressure, that is if your lamp is G9 then there will be no transformer above the lamp! This is a very good difference.

3, G4 from the appearance point of view, two pins are very similar to the pins of the embroidery needle, of course, the volume of the bulb is also smaller, and the G9's two pins are like oval ring pins, not like a needle Pins. Of course, the volume is slightly larger.

4, for a regular manufacturer of lamps in terms of speaking, according to national standards, regardless of which country's standard, are to be posted w tags, (or called lamp cap), the request is to be posted on the customer in the light bulb or change When light bulbs must be easily visible, they are usually placed near the lamp. Of course, some manufacturers may not stick to one of the heads of crystals for many heads of crystals. If one is not posted, then you buy is almost like three no products. If there are tags, how many volts do you see above? G4 can only do low pressure, and generally do 12V, and for G9, because it is only doing high pressure, so it should be written about 220V.

5, Also, if you buy a lamp with a light bulb at the time, then in addition to the distinction I said above, there should be a parameter mark on the light bulb, such as writing 12V 20W or writing 220V 40W, etc., the words on one bulb can't be seen clearly. You can look at the words of other bulbs. If all of them are not printed, the quality of the lamps you buy is not guaranteed. In fact, there are also JC bulbs (referring to the capsule-shaped halogen bulbs) for the G4 bulbs.

6. Again, to remind you to buy a replacement bulb, we must pay attention to the same as the rated model in addition to the outside, the power of the bulb can not be greater than the rated power, such as the G4 bulb is equipped with a transformer, if the replacement bulb If it is larger than the rated value, the transformer cannot withstand it and it will easily cause the transformer to burn out.

7. Precautions for use of high-voltage products:

1 Select the appropriate input voltage product according to the local power condition;

2 For the overall installation, the number of lamps needed for the initial budget should be preliminary, and then the total power is calculated and the power distribution plan is designed based on the budget amount and the rated power of the individual lamps;

3 When plugging or unplugging the product, it must be operated under power off conditions

4 Please use the matching lamp holder when installing;

5 During the use of the product, it is forbidden to touch the metal pin part of the lamp cap, otherwise there will be danger of electric shock.

6 All products are used indoors and must not be stored in a humid environment or used in a place where it is exposed to rain.

7 can not insert and pull products too often;

8 The lamp body heat is a normal heat dissipation phenomenon.
