Do LED bulbs heat up?

Image
Incandescent lamps undoubtedly heat up Incandescent bulbs are known for their high heat output when used. This disadvantage makes it difficult to replace faulty bulbs, as you have to wait a few hours for them to cool down and handle them safely. Specifically, the dispersion of heat is due to the internal tungsten filament which, when crossed by electric current, generates not only light but also heat. Precisely for this reason, these light sources are considered energetically inefficient. Only 10% of electricity is converted into light. The remaining energy is dissipated through heat, leading to: ·         A reduction in the life cycle (average duration fluctuates between 800 and 1200 hours) ·         Loss of electrical resistance of the internal filament ·         High energy consumption and frequent replacement of the light source The LEDs heat up but not in the same ...

What is the UGR?

Image
Unified Glare Rating The acronym UGR is commonly used to refer to Unified Glare Rating, that is the degree of luminous harassing glare. This index is subject to European and national regulations that establish the limits allowed in working environments. Specifically, in Italy the UNI 11165: 2005 standard applies, which indicates the criteria for calculating the unified glare index deriving from artificial light sources. Why is the UGR important? Lighting is often underestimated not only by individual consumers but also by companies. However, it is important to ensure that it is adequate for the work environment so that work activities can be carried out in complete safety. In fact, lighting not only guarantees a higher level of safety but also affects the well-being of workers and stimulates productivity. For this reason, it is advisable to plan carefully the lighting. How is the UGR measured? The UGR takes into consideration several factors such as the quality of the lig...

Why flicker with dimmable LED lights?

Image
The LED lighting can be a complicated job, and since there is no standard for LED dimming, there is no guarantee that a particular lamp will work with a certain dimmer. Incompatibilities between lamps and dimmers can cause flickering reduced adjustment ranges and can also cause damage and reduce lamp life. Our lamps are compatible with most state-of-the-art dimmers, but due to the variety and constant development of new units, not all suitable dimmers will be included. 1: The minimum dimmer load is not satisfied. Dimmer switches (mainly avant-garde) have a minimum load of 40 watts, if this load is not satisfied, flicker may occur. Flicker will be more noticeable at lower levels, i.e. when trying to lower below 50%. One way to solve this problem is to use a resistive (or fictitious) load. Another way is to use an LED dimmer; this type of dimmer switch has been tested almost specifically for use with LEDs and has a lower minimum load. 2: Most commonly, the combination ...

How to choose the right beam angle for LED downlights?

Image
What is the opening angle? The beam angle is something you need to pay attention to when choosing the right LED lighting for space. This is as important as the color temperature. The angle of the beam indicates the diffusion of light from the light source. A narrow beam gives a concentrated light that is better for accent lighting. A wide beam gives a more general and softer light. Most LED lights are available in a choice of beam angles. From a very narrow 15 spots to a wider 60-degree spot. A narrow beam angle makes the light more concentrated and intense. A wider beam angle will distribute the light better to more areas of the room. Knowing how to correctly use beam angles can greatly improve the lighting effect in a room. How to choose the beam angle for LED downlights? The light must be directed towards a specific object or person, not an area, it is necessary to choose a narrow beam angle; When lighting a large room etc., it is necessary to choose th...

How to choose track lighting?

Image
What is track light? According to some relatively complex and rigid lighting environments or engineering projects for commercial lighting (such as clothing store, showroom, Stage 4 3500k led track light 30w white color project 300x150 - How to choose track lighting decoration shop, jeweler supermarket, etc.), more and more users require better track light to replace the traditional track lighting in order to obtain a better lighting effect. When a ceiling cannot accommodate recessed lighting, due to the beams, for example, track lighting allows the luminaires to be positioned near the ceiling, maintaining visual transparency. Consider your lighting needs Before selecting a track system and the accompanying elements, it is important to consider the specific lighting tasks to be addressed. General ambient lighting, accent or wall wash lighting and work lighting all have different purposes and each requires different positioning and positioning. Ambient and general...
