There are various reasons why the mosquito killer lamp does not light up, what is the reason why the

There are two situations when the mosquito killer lamp does not light up:

First, the 220V mains power has not entered the mosquito killer lamp circuit, and there is no voltage on the high-voltage power grid at this time. In this regard, you can first check whether the 220V mains power is normal, and if it is normal, then check whether the power plug and socket are disconnected or have poor contact. If there is still no problem, you need to disassemble the mosquito killer lamp for inspection, usually most of the power cord solder joints are loose, and the fault can be eliminated after re-welding.

A few may also be caused by an internal open circuit in the power cord, which can be reconnected or replaced with a new one.

The second is that the 220V mains power has entered the mosquito killer lamp circuit, and the voltage of the high-voltage power grid is normal, which indicates that the fault is only in the ultraviolet fluorescent tube circuit. Detachable mosquito lamp shell, first see whether the lead between the lamp tube and the printed circuit board is desoldered or broken, if so, reconnect; If not, check whether the contact between the lamp tube and the lamp holder is good. If the contact is poor, the lamp can be re-tightened.

If there is no problem with the contact, it is that the lamp is broken, and the common thing is that the lamp is used for a long time and the lamp is leaking, and it is generally necessary to replace the lamp with a new lamp of the same specification.

It is worth pointing out that the service life of the lamp is not only related to its own quality, but also has a lot to do with the use method and the fluctuation of the mains voltage.

Therefore, the use of mosquito killer lamps should minimize the switching of power supply, it is best to switch on and off only once a day, and it is best not to use it indoors where the mains voltage is too high or too low, so as to avoid premature aging of the lamp and prolong its service life.

Electronic starters (or ballasts), lamps, power switches.

The mosquito killer lamp is also equivalent to a night light, which is used to attract mosquitoes, although it is a little bright, but it does not affect sleep.

Mosquito killer lamps are ultraviolet lamps, and when exposed to ultraviolet rays, fluorescent agents will emit light.

1.Circuit.

Test whether the circuit is damaged, and the circuit damage can cause the mosquito control lamp to not light up.

2.Switch. Check to see if the switch is normal.

3.Voltage. Check whether your voltage is stable.

4.Lamp. If the lamp is burned, the mosquito killer lamp will not light up directly.

The wick of the mosquito killer lamp is broken, or other parts of the mosquito killer lamp are damaged.

The mosquitoes disappear as soon as the lights are turned on, which has something to do with the way mosquitoes forage。Because when mosquitoes want to forage for food and suck blood, they track and locate them based on the heat emitted by the human body or other mammals. When the lights are off, the biggest source of heat in the room comes from the human body, and mosquitoes can bite people's bodies with great precision, and even buzz in their ears.

But when we turn on the light to look for mosquitoes, the heat emitted by the lights will affect and interfere with the mosquitoes' foraging location, so that the mosquitoes will hide, so as soon as we turn on the lights, the mosquitoes will disappear.

Characteristics of mosquitoesMosquitoes generally prefer moist and shady places, and their breeding grounds are generally in rivers, lakes, streams, forests, grasslands and other places where there are water sources. Mosquitoes fly upwind in search of a host and drift back to their habitat downwind. Mosquitoes do not like to travel, they generally move in the range of 50 to 100 meters.

In the case of long distances, mosquitoes generally want to find people or animals, mainly relying on the mosquito's sense of smell to perceive the change in the density of carbon dioxide in the air caused by the carbon dioxide exhaled by humans or animals. (Note: CO2 itself does not attract mosquitoes) In normal cases, mosquitoes prefer to be active at the height of meters.

After pressing the mosquito killer switch, the light does not turn on.

Analysis and Maintenance: The cause is damage to the circuit or lamp.

1 .The power switch k is damaged. It can be taken apart for inspection. If damaged, it can be replaced with a normal power switch of the appropriate size.

2.Solder lamp leads or capacitors. Remove the set screws under the base and open the cover plate of the base to reveal the printed circuit board and components.

First, check that the lead wire of the lamp and C1 are desoldered. If the wire is broken or detached or the C1 is desoldered, it should be connected or re-soldered.

3.The lamp is damaged. If the switch, connection, and C1 are normal, the lamp can be judged to be damaged. Weld the lamp leads, grasp the top of the lamp, and pull it from the bottom to the top. The lamp is a 5W self-ballasted fluorescent tube and can be installed in the reverse process of disassembly.

Take a closer look: <>

Because in the natural bridge and environment of the artificial source of light, there is no ultraviolet light source at night. Ultraviolet lamps attract a lot of text, leading people to mistakenly think that bloodsucking codes are empty and mosquitoes also like to be blind to ultraviolet rays. In fact, what really attracts mosquitoes are animals and carbon dioxide, smell and infrared.

Therefore, mosquitoes are attracted to the infrared rays produced by the heat generated by the lamp, rather than the ultraviolet rays. Ultraviolet mosquito killer lamps have an attraction effect but no mosquito killing effect.

In order to eliminate mosquitoes and flies, many friends will choose to use mosquito killer lamps, but mosquito killer lamps sometimes cannot catch mosquitoes, so what are the reasons why mosquito killer lamps can't catch mosquitoes? Let's take a look.

1. There are many reasons why mosquito killer lamps cannot catch mosquitoes, and if the reasons are different, the treatment methods will be different. When it is found that the mosquito killer lamp cannot catch mosquitoes, you should generally check in detail whether the placement of the mosquito killer lamp is correct, if the placement of the fake mosquito killer lamp is incorrect, the mosquito killer lamp will naturally not be able to catch mosquitoes.

2. Under normal circumstances, the height of the mosquito killer lamp from the ground should be kept at about meters, and it should be ensured that the mosquito killer lamp can operate normally. In addition, the brightness of the perimeter of the mosquito killer lamp should be slightly dim, otherwise the surrounding light may affect the mosquito control effect of the mosquito killer lamp.

3. The inability of the silver mosquito lamp to catch mosquitoes may also be caused by the poor quality of the mosquito killer lamp. If the mosquito killer lamp used by the owner is an inferior product, then the mosquito control effect of the mosquito killer lamp will inevitably be unsatisfactory. If you want to solve the problem, then it is best to choose to use high-quality mosquito killer lamps produced by regular, well-known and large manufacturers.

4. The mosquito killer lamp cannot catch mosquitoes, and it may be caused by the owner using the mosquito killer lamp at the wrong time. If the owner uses the mosquito killer lamp to catch mosquitoes during the day, then the mosquito killer lamp will naturally not catch mosquitoes. Because in the daytime, mosquitoes generally rarely move, and mosquito killer lamps are generally unable to play a normal role in mosquito control during the day.

5. Because during the day, the indoor light is generally very bright, even if the mosquito killer lamp is turned on, the light emitted by the mosquito killer lamp is generally unable to attract mosquitoes, so the mosquito killer lamp will naturally not be able to catch mosquitoes. If you want to use a mosquito killer lamp to catch mosquitoes, it is best to use a mosquito killer lamp at night. When the mosquito killer lamp is turned on, the light emitted by the mosquito killer lamp will attract mosquitoes to catch them.

6. If the mosquito killer lamp cannot catch mosquitoes, it may be because the mosquito killer lamp has no electricity or is damaged. Once the mosquito killer lamp runs out of electricity or there is a damaged canopy banquet, the mosquito killer lamp will not be able to operate normally, and naturally it will not be able to catch mosquitoes. When using the mosquito killer lamp, you should observe in detail whether the indicator light of the mosquito killer lamp is on, if it is not on, it means that the mosquito killer lamp has a fault and needs to be repaired or replaced.

The above is a detailed introduction to the reasons why mosquitoes cannot be caught by mosquito killer lamps, I hope it can help friends in need. When using mosquito killer lamps, it is important to ensure that the mosquito killer lamps can operate normally, are placed in the right place, and are best used at night, so that the mosquito control effect will be guaranteed.
