There is a picture of the truth: horizontal evaluation of 10 LED lights

As the fourth generation of electric light source, LED light emitting diode, with its many advantages over the traditional lighting products. Now the price of LED has declined, and gradually entered the field of general household lighting. So the value of LED lighting products are not worth buying? Is it really better than incandescent and energy-saving lamps? I will bring you 10 models of LED lighting products, to tell you how the price of different products.

First of all, introduce the choice of products. The horizontal evaluation of the main products for home lighting users, so all choose a suitable home lighting LED bulb lamp, nominal power is 7W, light color is also a unified choice of white. In order to be more representative, Hengping choose brand products covering domestic and international major brands, and other yet to launch 7W bulb or a white light LED products manufacturers products without cross evaluation.

Hengping choose 10 LED bulbs respectively (sorted by product trademark Chinese Pinyin sequencer: often can) QPX2-0701 bulbs, PHILPS LED bulbs, FSL A60-7 bulbs, John noble source series LED bulbs, crystal reflecting lighting B07 bulb, Laiwei photoelectric Jazz Shi series LW-LB7W bulb lamp, LED bulb lamp bright Yun Mei, Ming can BPZ 220/5 green D30BP2 bulb, bright star OSRAM classic A type LED bulb, QQP-AC220V-W07A bulb dry bulb.

LED lamp 7W is mainly used to replace 40W incandescent lamp, energy saving lamp 8W is also used to replace 40W incandescent lamp, in order to compare more intuitive in some numerical aspects, Hengping also added a 40W incandescent lamp (incandescent lamp for general lighting 40W Ge Corp) and a 8W (from the town of energy-saving lamps the flow of fluorescent lamps with super executive 8W general lighting OSRAM), in some parameters of product and Hengping products compared to look at the replace incandescent lamp LED lamp is more outstanding.

The main parameters of Hengping test will include illumination, temperature and power, in comparison of each of the parameters, we will do the analysis summary of the performance of the product in the final assessment of the cross we will do a comprehensive analysis of the actual performance of the product.

Disassembly analysis of LED bulb lamp

The author believes that a simple understanding of the LED bulb lamp is very necessary, so in the cross evaluation before, we brought you the LED bulb lamp dismantling analysis introduced.

The 10 round of the evaluation of the LED bulb light

LED bulb lamp is a LED light emitting diode as a light source products. In order to better replace the traditional lighting products, LED lamp made of spherical shell, the use of the most common E27 screw mouth, so it has become our common bulb shape.

The structure of LED bulb: screw, base, circuit, radiator, LED, softboxes. LED bulb with E27 screw is the most common bulb interface, you can maximize the compatibility with the existing lighting fixture; the base is used for connecting a screw and a radiator, and avoid electric shock, the circuit of the bulb is fixed on the base, the household alternating current into direct current to provide a stable operating current is LED; LED fixed in the radiator, the radiator will work when produced by direct contact with air to dissipate the heat, the light emitted by the LED lamp through the transition, so that the light is uniform and soft, suitable for the use of lighting.

Structure of LED bulb lamp

The bulb of different LED is different in detail, but the principle is the same. Due to the use of a higher luminous efficiency of the LED as a light source, LED lamp can be in the case of less power consumption to provide more efficient lighting, we will be in the next round of evaluation of its test.
