With the growing demand for energy conservation and environmental protection, we are increasingly using LED lights in lighting design. The LED market can be described as a mixed bag of good and bad. Various manufacturers and merchants are pushing and blowing their own products. So how much do you know about LED linear lights?

　　 The selection of LED lamps includes appearance, heat dissipation, light distribution, glare, installation and so on. We will not talk about the parameters of lamps and lanterns today, only the light source: will you really choose a good LED light source? The parameters of the light source mainly include: current, power, luminous flux, light attenuation, light color, and color rendering.

　The misunderstanding of LED linear lamp purchase

　　 Misunderstanding one, the expectation of the actual service life is too high.

However, like all basic light sources, the luminous flux of the LED decays over time. Therefore, although LEDs can emit light for a long time, the attenuation of LED lumens is affected by many environmental conditions such as ambient temperature, humidity, and ventilation. Lumen decay is also affected by control, thermal management, current levels, and many other electrical design considerations.

　　 Misunderstanding two, regard the actual luminous angle as the effective angle.

The light-emitting angle of LED is divided into effective angle and actual light-emitting angle. The angle between the direction where the luminous intensity value is half of the axial intensity value and the luminous axis is the effective angle. The viewing angle of 2 times the half-value angle is the actual light-emitting angle. Angles other than half of the axial intensity are not included in the effective angle in practical applications because the light is too weak.

　　 Therefore, consumers should pay attention to the actual light-emitting angle of the product when purchasing products. When calculating the number of products used in the project, the actual light-emitting angle shall prevail. The effective light-emitting angle can only be used as a reference value.

　　 Misunderstanding three, the greater the power, the higher the brightness.

The brightness of the LED is measured by the luminous intensity. The luminous intensity refers to the luminous intensity in the direction of the normal line (the axis of the cylindrical luminous tube), that is, the luminous flux emitted per unit solid angle, and the unit is candlelight. Since the luminous intensity of general LEDs is small, the luminous intensity is usually used as the unit of millicandela. Generally speaking, a light source emits its luminous flux with different intensities in different directions. The intensity of visible light emitted per unit solid angle in a specific direction is called light intensity, or axial brightness for short.

　　 First of all, we often say: "How many watts of light do I want?" This habit is a continuation of the previous traditional light source. At that time, the light source had only a few fixed wattages. Basically, it can only be selected from those wattages and cannot be adjusted freely. With the current LED, the driving current is slightly changed, and the power is immediately changed! Are you still asking for power? Beware! When the same LED light source is driven by an excessive current, the power is increased, but the light efficiency will decrease and the light attenuation will increase.

　　 LED linear light is a flexible LED decorative light and also a kind of LED wall washer. It can be installed in a single or multiple combinations, and has the advantages of long life, easy bending, and low power consumption.

LED linear light is a very simple product. Its appearance, structure and functionality are almost the same on the market. General LED linear lights are assembled with SMD LEDs, and they can also be assembled with in-line LEDs. .

　　The shell of the LED linear lamp is made of aluminum alloy, which is not only simple in structure, but also beautiful in appearance, and it is strong and corrosion-resistant. At the same time, the surface of the lamp has also been treated with electrostatic spray, which can cope with various harsh weather conditions.

If the LED linear lamp is in a place with heavy dust, it is easy to let the dust cover its radiator, which will affect the normal heat dissipation of the lamp; if it is in a place with oily smoke and water vapor, it will easily affect its normal operation, so you should try your best when installing it. Avoid these places. If you can't avoid it, you need to take all protective measures in advance.

　　 LED linear lights are suitable for various buildings, indoor and outdoor local or contour lighting. Generally, outdoor linear lights are suitable for lighting the facades of various bridges, buildings and outdoor advertisements; indoor linear lights are suitable for lighting indoor dark grooves, wardrobes, cabinets, etc.
