Heat is the enemy of LED bulbs. Although LED lamps may have a similar shape to incandescent or fluorescent lamps, the LED chips inside the lamp are not so different from the chips in your laptop or other electronics.

For this reason, they cannot be used in microwaves or ovens, and some of the larger LED lights can use a passive radiator or internal fan to prevent overheating of the electronics. Enclosed luminaires that do not provide adequate ventilation can dramatically affect the temperature of the LED lamp, resulting in overheating and shortening the lamp life. This is why some bulbs should not be used in a closed ceiling fan or a fully enclosed street lamp.

We would like to consider some frequently asked questions about indoor luminaires and indoor luminaire lamps to help you get the most out of your light bulbs.

What is an indoor lamp?

A closed fixture is any fixture or application where the bulb is enclosed in such a way as to prevent proper air flow or ventilation. This includes, but is not limited to, street lights, where the bottom is glass or plastic instead of open-air, indoor lights and recessed lights with a lens.

For LEDs, one of the main disadvantages is the strong dependence of the lifetime on the temperature on the crystal. With increasing temperature, rapid degradation begins the luminous flux decreases and the period during which the luminous flux remains acceptable. A good heat sink to the housing of the LED lamp is a guarantee of its long-term operation. In this regard, we can say that LED lamps cannot provide such a heat sink, and the radiators used in them will be effective only in open fixtures with good convection. In closed luminaires, such lamps will have a very limited service life. A specially designed LED lamp should provide the most efficient heat dissipation from the LED crystal to the lamp housing. If we compare two LED lamps of the same power, the longer will be the life of the one whose body is more heated.

How to find out if a light bulb is designed for use in closed luminaires?

Here you should look at the specifications for each LED lamp. They can be written on the box or on the instructions inside. If the value for “Enclosed Fixture Rated” is indicated as “yes”, this means that the bulb can be used in indoor luminaires. If “no”, the lamp should not be used in closed luminaires. Using the LED light in a closed lamp when it is not designed for this can cause the lamp to overheat, which can damage the lamp and the lamp. Even a small amount of heat can shorten the life of the lamp and prevent you from enjoying the full value of your investment.

Can a lamp for an indoor luminaire be used in outdoor luminaires?

Yes, just because the light bulb is designed for closed luminaires, this does not mean that only such a luminaire is required. To use the lamp in a closed fixture, it must be designed to handle the heat of the enclosed space. Outdoors, this is not a concern. Another reason for buying indoor luminaires with bulbs is to use them outside. You may have garden lights or fully enclosed street lights that require a closed light bulb. Since the bulbs are completely protected from rain and other elements, the lamp should not be designed for damp or damp places that must be used in outdoor enclosed fixtures.

you can use more type of led lights in indoor lighting, for example, led strip light, slim panel lights, ceiling light, downlight and spotlight,
