Deep disassembly and evaluation of Nanoleaf Bloom LED bulb lamp

Today, we want to dismantle the environmental technology company Nanoleaf green launched a very avant-garde design of intelligent LED bulb Nanoleaf Bloom.

Nanoleaf Bloom is not used in the middle of the hardware or application operation, but the use of existing general bulb switch can be controlled, is a more intelligent smart bulbs. In addition to intelligent control, Nanoleaf Bloom did not change to such pursuit, is still a "smart LED ball most energy of the world" bubble, the current evaluation evaluation we will carry out a full range of Nanoleaf Bloom and the depth of the dismantling.

Nanoleaf Bloom product information

The dismantling and testing, by the Engineer Hu Xiaokun Voight Foshan Testing Technology Service Co. Ltd and its team.

Gossip less, the following is the text of the article.

Let's take a look at the product and lighting diagram.

On the electronic scale, take a look at its net weight:

Look at the lighting effect:

In the light of the day, the impact of the environment, the brightness may not feel enough, it does not matter, to the wind inside the test cover:

Oh, my colleagues said a little dazzling, presumably because no shade, exposed by light.

Whole lamp test

Next we will start a comprehensive test of the product.

Photo biosafety

Take a look at the first test that can be done by IEC/EN 62471:

Test no problem, through, the following is the detailed data:

Optical parameters

In order to ensure the accuracy, the integrating sphere and distributed photometer were used to measure the luminous flux.

Integral ball and distributed photometer for different test methods, the data is slightly different, but are basically close to the luminous flux of 1145 LM, 114 lm/W light effect, color temperature 3015K, power 10.28W, PF 0.92, CRI 82.3, and the nameplate identification 10W, 1200lm, 3000K, CRI 80 is basically the same, optical parameters the performance is very good, brightness equivalent to 100W incandescent or energy-saving lamps with 30W, claiming the title of world energy ". Specific reference to the following report:

Light distribution curve

Although the industry has been advocating the effectiveness of LED light, but compared to many of the past product testing, the measured light efficiency reached 114lm/W, this is still the first. But for the enterprise data, proposed the question, that the actual flux, the flux is lower than the test product in this regard, the laboratory instrument after receiving feedback correction and re test, but still with the parameters measured before no entry. In order to maintain fairness and objectivity, the report will be provided by the enterprise side data presented for your reference. At present, there are some differences in the parameters measured by different test equipment, which is considered as the reason for the inconsistency of the two test data.

EMC test

EMC test results are required by the standard, which will be found in the back of the dismantling, the corresponding EMC countermeasures are reflected, some of the data are as follows:

Radiated disturbance (CDN) test data

Conduction test data

Lamp test

To discuss the evaluation scheme, we are most worried about is the lamp of torsion, before the Nanoleaf One when dismantling the lamp torque test has been available on the 1.24Nm to hear when the bulb creaked, torque is not qualified, do not know what will happen to the Nanoleaf Bloom performance?

Look at the test chart:

Torque 3Nm, time 1 minutes, pass the test, but colleagues holding the bulb, PCB corners let colleagues hands feel the pressure, but he persevered.

Then, we do the next test of the tensile strength of the lamp cap, 40N, 1 minutes, the first to tell the results, through:

Next, look at the dismantling of the bulb.

Fiberglass shell.

See the site can be opened at an angle of five eleven (five twelve corner site), Tron cube, want to make every piece of stretch, making a better perspective.

If dismantling contrast Nanoleaf One, Nanoleaf Bloom and found significantly different, because the drive circuit of Nanoleaf Bloom has changed a lot, and the increase of the dimming control part in the assembly of products has greatly changed.

Following the temperature rise test, we use the layout of the thermocouple, the acquisition of temperature parameters:

After the completion of the thermocouple, the temperature rise test.

When the input voltage is 240V, the temperature rise test about 30 minutes later, the whole lamp power is reduced to about 8.5W, the following temperature curve can be clearly seen:

In addition, a test was carried out under the condition of 100V voltage.

Can be seen from the data, no more than 80 of the highest temperature rise, even behind the LED lamp and lamp cooling copper, the temperature is only 70 degrees to temperature control is very good.

The dismantling of beads

The whole lamp test is done, we need to do a dismantling of the most important LED lamp:

The following treatment with acetone to package glue and toner, after the treatment of LED, but start peeling glue package was too large, the gold basically break, and no fault, no longer to deal with:

Below is the LED chip image under the high power microscope:
