LED light angle is divided into effective angle and the actual light angle. The luminous intensity value is half the direction of the axial intensity and the direction of the light-emitting axial (normal) is the effective angle. Half of the half angle of the angle (or half power angle) is the actual light angle. In the axial strength of half the angle because the light is too weak in practical applications do not count the effective angle. (The picture below shows the side view of the piranhas particles, the angle between the solid line and the dashed line is not included in the effective angle)
Many salespeople in marketing LED for some reason may give customers to provide some fuzzy information, resulting in misleading, such as LED life of about 100,000 hours, where the 100,000 hours is the manufacturer expected LED life. As the light source of the light, the brightness of the lamp has a process of gradual decay and darkening (such as fluorescent lamps) , Energy-saving lamps), this process referred to as light failure. In the application-level LED, the light failure of more than 50%, the human eye can clearly feel the brightness of the change, then the product brightness we think is not suitable for lighting. Many manufacturers and engineers in the use of low-cost LED three months to six months or so, often found that the brightness of LED is not as bright as the installation of light, or even almost no, it is because the LED lamp failure did not take into account the reasons. In summary, we have to pay attention to the purchase of LED light decay of its speed, rather than the use of time.
In choosing the appropriate chandelier, ask yourself, "will the chandelier effectively blend into my room's existing furnishings?" Chandeliers can blend with your decor or serve as a distinctive focal point in the room. Take note that a chandelier adds extra style to a room, but is considered a poor light source. It is important to note that a chandelier doesn't need an abundance of bulbs even if a room is big, and allow other lighting in the room to supplement a more restrained chandelier.Candle Wall Sconces And Lanterns In Home Dcor
With expenses climbing the graph we need economical trimmings. A saving advantage of low-voltage outdoor lighting is that one does not need a professional for installation. The money saved can be spent on high-quality fixtures and landscaping. Some low voltage light fixtures work on solar energy and once charged work when sensors activate the lights on sunset.
