Depth evaluation: 179 yuan of Bluetooth smart bulb which strong?

With the concept of smart appliances Home Furnishing "and" intelligent "gradually into daily life, is accepted by more and more people, through the intelligent terminals such as mobile phone intelligent control of a variety of products has become a new market demand. Intelligent lighting, as an essential part of smart home, but also one of the most practical areas, nature has become a new competitive landscape of various manufacturers. Thanks to the rapid spread of low-power Bluetooth and other short-range wireless communication technology, a variety of smart bulbs at home and abroad in the public view.

In China, there are two equally to the retail price of 179 yuan Bluetooth smart bulbs, has become the focus of everyone's attention. One is the Yeelight Blue II, another is the magic iMagic smart bulbs. This is the first launch of Bluetooth smart light bulb manufacturers. As everyone knows, the smart bulb Yeelight launched contains ZigBee technology based on the Sunflower series (now known as millet smart bulbs) and Bluetooth smart lighting based on BLE Technology (Blue II is the second generation of products). The magic iMagic smart bulbs also after the product iteration, a new upgrade in the first generation of products. Two products with similar features, the price is the same as 179 yuan, consumers how to choose it?

Recently, many enthusiasts have their own dismantling of these two bulbs, so now we focus on each evaluation, comparative analysis.

From the outside to the inside, we first look at the packaging and appearance of two products.

Yeelight uses the simple kraft paper outer packing, the black pearl cotton lining and the paper instruction booklet, the silver lamp body, the glass shade.

IMagic packaging for light yellow texture paper, white EVA backing, silver, gold, white three color options, PHILPS fluorescent coated glass shade, no paper instructions, but can scan the two-dimensional code to download the electronic version.

From the product packaging, Yeelight packaging is obviously millet style, simple and elegant, iMagic packaging design is unique, has its own style, literary sense is stronger; the lamp body, both for its own mold production, this will throw off a few blocks many copycat manufacturers. It is worth mentioning that, in addition to the original PHILPS iMagic lamp Hue silver, there are specially designed white and gold optional. This is the first in the industry, but also for some manufacturers to imitate later.

The two products have full color RGB color, color light effect is carried out by RGB three color mixing lamp. The following two pictures for the real effect (on the Yeelight, under iMagic). As for the mixed color mixed light effect, we can look at their own comparison.

Magic iMagic

After comparing the color light, we will compare the effect of white light. The effect of white light to a large extent determines the usefulness of the bulb. Yeelight Blue II 6W iMagic nominal power, super smart bulbs nominal power of 6.5W, both nominal flux is 500lm. As for the actual situation, you can refer to the following real renderings (left Yeelight Blue II, right iMagic).

Next we open the finished appearance, lighting, lamp and lamp panel layout see materials.

The lamp board two bulbs also use the aluminum substrate, Yeelight Blue II (left) with 6 beads, 3 white LED (allegedly CREE), RGB 1 (unknown brand); iMagic (right) with 23 beads, 12 white LED (allegedly PHILPS Lumileds 11), a color lamp (unknown brand). Pictured above, the light board layout, iMagic lamp layout is more reasonable for some materials, also more sincerity.

Next, we look at the design of the main control board. The two also uses a low-power Bluetooth chip TI CC2540. As for the production process, Different people, different views. Don't say it. Look at the picture......

Look at the structure of the lamp body design, smart bulbs and ordinary LED bulb is a big difference, that is, the lamp body temperature will have a decisive impact on the performance and stability of the product. At very low and very high temperatures, the components of the wireless control panel may fail, causing the bulb to lose control. In 2014, there was a manufacturer of light bulb products on display at the Guangzhou Guangya Exhibition, which had to be restarted once every 10 minutes to correct the control panel.

The body of the Yeelight lamp body adopts the glue filling process, so as to play the role of the integral stability and the promotion of heat dissipation, which is a common practice in the industry. The iMagic lamp body adopts three layers of composite structure, the inner cavity is not filled with glue, and only depends on the optimization of the structure and material of the lamp body to accelerate the heat conduction. It can be seen in the structural design and heat treatment on a lot of effort.
