LED light bulbs are easy to break, not bright, flashing, and slightly bright, why should I repair?

At present, the quality of LED bulbs on the market is uneven, and some may be broken in a short time. So what should be done? Here are some ways to sort out.

Let's take a look at the three types of light bulbs commonly found on the market from the outer casing material:

Full plastic LED bulb

This LED bulb is the cheapest on the market and the lowest quality, lowest end product. Needless to say, the problem is the most. Because the materials used are fundamentally determined, all plastic LED bulbs are generally resistant to buck (large wattage is also driven by linear constant current), some of the panels are even used for fiberglass, and even cardboard Yes, the all-plastic shell has no way to dissipate heat, and it will not last long when born. There may be large wattages with aluminum radiators.

If it is broken, throw it directly, there is nothing to repair.

Aluminum plastic LED bulb

These types of bulbs are currently relatively stable on the market and are the most used. Its outer casing structure is plastic outside and aluminum heat sink inside. If the cross-flow constant pressure drive used by the conscience manufacturer, the service life is very long. If the material does not cut corners, there will be no problem.

If it is broken, the light source is broken and the light source is changed. The driver is broken and the driver can be changed.

All aluminum LED bulb

Such bulbs are a popular solution on the market in previous years, as material cost factors are gradually being replaced by aluminum molding. Of course, this use of all aluminum, heat dissipation is very good, and the life is also very good. The only drawback is the high cost of the material and the high price. In the case of sufficient materials, there are few problems.

If it is broken, the light source is broken and the light source is changed. The driver is broken and the driver can be changed.

The LED bulbs are the three types mentioned above from the outer casing material: all plastic, aluminum plastic, and all aluminum.

The LED bulbs are classified from the driving power source: resistance-capacitance buck, linear constant current, constant current and constant voltage.

The drive power is the core of the light bulb. If it is broken, there may be situations:

1. The whole lamp is not lit,

2. The light is slightly bright,

3. The light flashes and flashes.

4. After the light is on for a while, it will not light up.

LED bulbs are from the light source: most of the current market is 5730 light source, of course, there are foot tiles and less watts.

If the light source is broken, there may be situations:

1. Some lights are on; some lights are not on,

2. The whole light is not lit,

3. Some lights have black spots,

4. The whole lamp appears to deviate from the normal color temperature.

Let's take a look at what is going wrong with the light bulb in the downlight?

It is a good choice to install LED bulbs in the downlights. In addition to the need to turn on the lights in specific places, you can buy bulbs in the downlights, which is easy to maintain and easy to maintain. Under normal circumstances, as long as the quality of the bulb itself is too good to be used as a light source in the downlight, there is no problem, but recently, many people have said that the bulb in the downlight is broken.

So, what is the reason?

I have a general understanding of the situation, and there are problems with the installation. Many of the bulbs have no gaps around when the LED bulb is installed. The bulb can't dissipate heat. The bulb is hot inside. The reason is so simple. Install the LED bulb in the downlight. There must be a certain gap around the bulb for the LED bulb to dissipate heat. As shown below:

Look at the picture below, so that the bulb and the downlight just fit, the LED bulb does not have any space for heat dissipation, it is easy to break.

Generally, the bulbs with good quality are at least 3 years old. It is easier to buy low-priced products. It is recommended to use aluminum alloy or aluminum casing with good heat dissipation, constant current and constant voltage drive, and LED bulbs.
