Choose a right light source for your chandeliers - LOHAS e12 led light bulb
Type of chandeliers suitable for different rooms
Chandelier is a high-end decorative lighting that is suspended on the indoor ceiling. All hanging lamps are classified into the chandelier category. The chandeliers have the most patterns. Commonly used European-style candlesticks, Chinese-style chandeliers, crystal chandeliers, parchment chandeliers, fashion chandeliers, cone-shaped lanterns, pointed-shaped lanterns, beam-shaped lanterns, pendant-ball chandelier, magnolia-shaped lantern, Olive chandelier, etc. The chandelier is suitable for living room, bedroom, dining room, corridor, hotel and other lobby. Generally, the more beautiful chandeliers usually have more complicated shapes and lampshades. If the lamps are wet and dusty, the lamps are often rusted and paint-shedded, and the lampshades are gradually dimmed due to dust. Without treatment, the average brightness of the chandeliers is reduced by about one year. Thirty percent, within a few years, the chandelier will be dim and dull.
Parameters you should know to choose a right light source for chandeliers丨LOHAS e12 light bulb is the best choice
Color temperature
The color temperature is based on a black luminous body, also known as a Planck radiator-emitting a specific color of light according to different temperatures, the unit is Kelvin, which is the color of the light. The lower the K value (color temperature), the redder the light color. The higher the K value (color temperature), the more blue the light color becomes. Generally, the color temperature of home improvement lamps is between 3000K-4000K(LOHAS e12 light bulb 3000k would be the best choice for your chandeliers ).
Although you can't see the flicker of the lights with your naked eyes, the eyes in the strobe light will obviously feel the swelling and fatigue of the eyes for a long time. Therefore, I naturally recommend using eye-protection lamps throughout the house, which is better for myself and my family.
The degree to which the index light source renders the color of the object itself is called color rendering, that is, the degree of color fidelity. A light source with high color rendering performs better on colors, and the colors we see are close to natural colors and have low color rendering. The light source has poor color reproduction, and the color deviation we have seen is also large, which is represented by the color rendering index (Ra). The CIE of the International Commission on Illumination has set the color rendering index of the sun to 100, and the color rendering indices of all types of light sources are the same. For example: the color rendering index of high-pressure sodium lamps is Ra = 23, and the color rendering index of fluorescent tubes is Ra = 60-90. The closer the color rendering index is to 100, the better the color rendering.
Lighting design ideas for your chandeliers
Beam Angle & Wall Distance
The beam angle refers to the angle between the two directions where the light intensity is equal to 50% of the maximum light intensity on the plane perpendicular to the centerline of the light beam. The 15 ° lamp has a smaller irradiation range, and the center light intensity is the largest, which can form a strong contrast during irradiation; the 24 ° irradiation range becomes larger, but the center light intensity becomes smaller, and the spot formed on the illuminated surface is softer. That is to say, the larger the light beam angle of the same power lamp is, the smaller the central light intensity is, and the softer the light spot is. On the contrary, the smaller the light beam angle, the larger the central light intensity and the harder the light spot. The distance of the lamp from the wall will also affect the height and effect of the light spot on the wall.
Illumination & Brightness
Illuminance is used to describe the degree of illumination on the illuminated surface (working surface). It is usually expressed in terms of the amount of luminous flux received in a unit area. Brightness is also a physical quantity used to indicate the intensity of light emission (or reflection) on the surface of an object. The ratio of the luminous intensity of the luminous surface of the viewed object in the direction of the line of sight to the projected area of the luminous surface perpendicular to the direction is called the surface of the luminous surface Brightness in candela per square meter (cd / m2). The details are as shown in the figure below: the brightness of the light source is both visual and sometimes affected by color temperature. Among light sources with the same luminous flux, a light source with a high color temperature will produce a false vision with high brightness. This "high-brightness" light source does not necessarily have a higher light effect than other light sources, and the illuminance is not necessarily higher than other light sources. It is just a glare "false light". Therefore, in the actual lighting application design and lighting energy saving planning, as long as the illumination is used to evaluate the rationality of the lighting design. With the same selection of lamps and the same power, the color system of the illuminated space is different, and the brightness perceived by the human eye is different. For example: black space and white space. With the same parameters, white space feels brighter.
Glare
First, let's talk about how glare occurs. When the brightness of a light source or object in the line of sight is much greater than the brightness that the eyes have adapted, people will have a dazzling feeling. This phenomenon is called glare. Glare can cause discomfort or reduced visibility. The normal field of view of a person is 30 degrees above the horizontal, and the direct light angle is controlled within 30 °, and the reflected light is also controlled to be within 30 °. The way to control glare is the proper protection angle of the lamp, a reasonable installation height, and the surface condition of the installation surface. The lamp itself is equipped with an anti-glare device.
