How can we avoid the misunderstanding of purchasing LED line lights?

How can we avoid the misunderstanding of purchasing LED line lights? With the growing call for energy saving and environmental protection, we are using more and more LED lights in lighting design. At present, the LED market can be described as mixed with good and bad, and all manufacturers and merchants are pushing and blowing their own products. So how much do you know about LED line lights? How much do you know about the misunderstanding of led line lights?

Misunderstandings in the selection of LED line lights

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

However, like all basic light sources, the luminous flux lumens of LEDs also degrade 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 depreciation is also affected by control, thermal management, current levels and many other electrical design considerations.

Misunderstanding 2, take the actual luminous angle as the effective angle.

The luminous angle of LED is divided into effective angle and actual luminous angle. The angle between the direction whose luminous intensity value is half of the axial intensity value and the luminous axis is the effective angle. Twice the half-value angle is the viewing angle, which is the actual luminous angle. Angles other than half of the axial intensity are not counted as effective angles in practical applications because the light is too weak.

Therefore, customers should pay attention to the actual luminous angle of the product when purchasing. When calculating the quantity of products used in the project, the actual luminous angle shall prevail, and the effective luminous angle can only be used as a reference value.

Myth 3: The higher the power, the higher the brightness.

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

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 only had several fixed wattages. Basically, we could only choose among those wattages and could not adjust them freely. And now the LED, if the driving current is slightly changed, the power will change immediately! Are you still asking for power? beware! When the same LED light source is driven by an excessive current, the power will increase, but it will cause a decrease in luminous efficacy and an increase in luminous attenuation.

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

The shell of the LED line light 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 its lamps has also been treated with electrostatic spraying, which can cope with various harsh weather conditions.

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

LED line lights are suitable for various buildings, indoor and outdoor partial or outline lighting. General outdoor line lights are suitable for facade lighting of various bridges, buildings and outdoor advertisements; indoor line lights are suitable for lighting indoor dark grooves, wardrobes, cabinets, etc.

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