With the increasingly mature development of lighting technology, and people's increasing emphasis on green environmental protection, LED light without mercury, pollution-free green lighting has attracted more and more people's attention and welcome. BYD Lighting has been focusing on LED lighting, and is striving to create high-quality LED products for consumers with the slogan of “refined LED light sourceâ€. The following introduces a BYD lighting LED candle light, model AL-C11A300 (hereinafter referred to as AL), and through a comprehensive analysis of data analysis, so that you can understand it more deeply.
Candle light is a kind of light bulb. It is named because its shape is similar to that of candle flame. It is widely used in interior decoration lighting, especially for crystal chandeliers. Let us take a look at the evaluation report of this product.
Exterior
BYD Lighting This candle light has a compact appearance and light weight (only 52g). The lampshade is made of transparent glass, and the lamp cup (heatsink) is made of aluminum. It is made by die-casting process. The surface is anodized and the appearance is beautiful. The junction between the heat sink and the Plastic part is tight, seamless, and free from shaking.
The lamp holder interface currently has two E14 and E27, which are convenient for users to purchase.
The glass-shaped lens structure in the lampshade has the function of reflecting and refracting light, so that the light transmission effect is better and the unique light pattern can be presented.
After measurement, the test candle lamp has a maximum diameter of 38.79 mm and a maximum length of 110.43 mm.
Optical performance
For ordinary consumers, the power, color rendering index and luminous flux of the luminaire should be relatively concerned. Below we have selected the professional testing equipment - the integrating sphere for the actual measurement.
The measured power of the test candle light is 3.4W, and the color temperature of 5700K is daylight color, giving a bright and comfortable visual experience.
The luminous flux is simply the sum of the amount of light emitted by the illuminator per unit time. Through the integrating sphere test, this candle light has a test luminous flux of 203.5 lm and a luminous efficacy of 58.72 lm/W, which can replace the traditional 25 W candle light.
The ability of a light source to color an object is called color rendering. The higher the color rendering, the more accurately the original color of the object can be reflected. The color rendering index of this candle light is 84.9, which can restore the original color of the object more realistically and provide a true visual experience.
In addition, the light intensity refers to the energy of visible light received per unit area, referred to as illuminance, unit lux (Lux or Lx), and is used to indicate the intensity of illumination and the amount of illumination of the surface area of ​​the object. Test using a distributed photometer: (Refer to the following test report for specific data)
Finally, the conduction test of the candle lamp, this is mainly to test the electromagnetic interference of the product. As we all know, all household appliances generate electromagnetic waves when they work. Electromagnetic waves of different frequencies will cause mutual interference. However, as long as the electromagnetic interference is controlled within the standard range, it will not affect the normal use of other household appliances. LED lamps typically use pulse width modulation (PWM) technology to achieve constant current supply and dimming of the LEDs, thus producing a degree of radio disturbance and harmonics. The LED products on the market are mixed, and many LED lights use inferior power supplies, which will cause interference to other home appliances during work, thus affecting the normal use of other home appliances and even affecting the service life.
Conduction test
The following is the conduction test data of BYD Lighting AL-C11A300 candle light
The above conducted test data shows that the indicators are within the limits of the quasi-peak and average values ​​required by the national standard GB 17743-2007 Limits and Measurement Methods for Radio Disturbance Characteristics of Electrical Lighting and Similar Equipment, and the test values. Not exceeding the standard limit, so the test passed.
With regard to the design life of candle lamps, BYD LED candle lamps have a design life of 40,000 hours, which is a big advantage over other brands of LED candle lamps with a design life of 25,000 hours or 30,000 hours.
Through the above test data, it can be seen that BYD Lighting has excellent performance in terms of energy saving effect and visual comfort.
In practical applications, it is suitable for indoor lighting, such as hotel lighting, home lighting, etc., not only has good lighting effects, energy saving and environmental protection benefits, but also no stroboscopic, high color rendering index can bring you comfortable vision. Experience.
