In-depth study of the light quality of an LED downlight from the color parameters||

There are many standards to measure whether an LED downlight is of high quality, and light quality belongs to the core level. As an important factor reflecting the quality of light, color parameters directly restrict the color temperature of the emitted light and the 'deviation degree' of the color, which cannot be ignored. Here we through the detailed analysis of the color parameters of an LED downlight of Optoelectronics, to in-depth study of its light quality. The LED downlights used in the airport terminal have good light color consistency and ideal light quality. Look at the 'color parameters' of this light (the following data is obtained after evaluation) IF-IDL series LED downlights. Remark voltage Vu003dV; Current Iu003dA; power Pu003dW; power factor PFu003dIn fact, the main basis for evaluating the quality of lighting is the comfort of light quality, and color parameters are important parameters that affect the comfort of lighting. The measured color temperature of this IF-IDL series LED downlight is K, which is in line with the theoretical K color temperature parameter. It is a positive white light (neutral light). It is easier for people to have a sense of rationality and sobriety in this hue, and can clearly judge things; The color rendering index of the distribution map reflects the degree of restoration of the true color of the actual illuminated object by the light emitted by the lamp. The greater the value of the color rendering index, the greater the display of the true color, and vice versa. The measured color rendering index of the IF-IDL series is (the color rendering index is greater than that is excellent), which is more than sufficient for places where the color needs to be correctly judged (such as an office); furthermore, the special display index R is, indicating that the downlight is red In addition, the color tolerance of the chromaticity diagram is SDCM, which is far lower than the standard stipulated by the SDCM, which means that the color tolerance control of this downlight has been quite excellent, and the color temperature is more 'just in name'. In general, the IF-IDL series is quite ideal in terms of color performance, from color temperature to color rendering index, to special rendering index and color tolerance. In addition to the color parameters, the excellent light quality is also reflected in the strong light effect. Take a closer look at the light effect. The IF-IDL series of downlight models have been measured by the laboratory. The luminous flux of the luminaire can reach lm, and the luminous efficiency is greater than lmW. Due to the selection of high-quality CREE LED chips, the light decay phenomenon is effectively reduced, and it is quite energy-saving. In terms of color temperature, the optional color temperature of this series of downlights includes three types: positive white light K, warm white light K, and cold white light K. From the above color parameter evaluation, it can be seen that its color temperature standard and high light color consistency are helpful to build a neat Uniform lighting environment. In addition, the beam angle of this downlight is °, the spot is uniform and there is no stray, and the halo transition is soft and smooth, which can easily create a satisfactory lighting effect. The photoelectric case of the VIP hall of Chongqing Jiangbei International Airport The photoelectric case of the baggage claim hall of Chongqing Jiangbei International Airport The photoelectric case of Intercontinental Hotel Shanghai World Expo As modern indoor lighting has high requirements for the color parameters of light quality such as the color temperature of LED downlights, just like the IF-IDL series of LED tubes A product with a 'right and true name' like a lamp can naturally stand out from the market and gain the favor of customers. Introduction Optoelectronics focuses on lighting design, production and construction, providing overall solutions for LED lighting projects such as airports, hotels, commerce, and offices, and is the designated lighting supplier for major domestic airports. ---Fax contact address: Lighting selection website on the floor of Changhong Science and Technology Building, Science and Technology Park, Nanshan District, Shenzhen
