The LED desk lamp that charges the mobile phone with wireless charging function has recently exposed a face at the Hong Kong Spring Lighting Fair. Many LED table lamp manufacturers have launched similar products.
Talking about the wireless charging of mobile phones, I believe that everyone is no stranger. Because as early as 2012, Nokia launched a wireless charging mobile phone, starting from Lumia820, up to Lumia1520, so many mobile phones support wireless charging, Nokia can be said to be the pioneer and practitioner of wireless charging, but because Nokia has declined, It has not caused much impact on the market.
Subsequently, Samsung and other mobile phone manufacturers have also launched wireless charging mobile phones, basically all of them are flagship machines, but for various reasons, this function of wireless charging has not been rapidly popularized.
Since last year, the wireless charging function has once again been pushed to the market. Many LED table lamp manufacturers have seized the “fresh point†that consumers are interested in, and launched products that wirelessly charge mobile phones. According to Gaogong LED observation, in the 2018 Hong Kong Spring Lighting Fair, many LED lighting manufacturers focused on wireless charging desk lamp products.
Among them, Shenghongliang Technology, as a domestic LED table lamp manufacturer, mainly focuses on LED table lamps, and its products include LED eye protection table lamps/LED dimming table lamps. At present, the LED table lamps produced by Shenghongliang Technology ranks first in sales (in the form of OEM) in Taobao and Tmall.
The person in charge of Shenghongliang said in a conversation with Gaogong LED, “Adding wireless charging function to the LED desk lamp is a new market trend. Shenghongliang has laid out this market since October 2017 and launched it. Related products. As far as our current market volume is concerned, there are not many orders. However, with the launch of iPhone8 and iPhoneX, the selling point of wireless charging will be slowly brought hot."
In addition, IKEA also launched the "RIGGAD work lamp wireless charging desk lamp", this wireless charging desk lamp uses the Qi standard to fuse lighting and mobile phone charging. At the same time, IKEA also launched the "NORDM RKE three-in-one wireless charger", which is more expensive than wireless rechargeable desk lamps. The device can charge at least three devices at a time.
It seems that when the LED desk lamp itself does not have much "attractiveness" in the lighting function, can the manufacturer successfully open the LED desk lamp market breakthrough by using the function of wireless charging the mobile phone?
In this regard, Li Zhaohua, general manager of Mingwei Electronics, a well-known IC manufacturer in China, believes that “in general, the wireless charging market is still relatively small, and there are more services required, and the cost of the cost is relatively high. Not very big. In addition, coupled with some existing technical problems, I think that the LED wireless charging desk lamp market is difficult to open in a short time."
Then, at the current stage, what are the problems that need to be solved on the road of mass-marketing of LED desk lamp wireless charging function? The industry generally believes that the following difficulties exist:
1. Low efficiency: energy storage efficiency is not as good as real contact;
2, the charging speed is slow: due to low efficiency, the charging speed is slower under the same input power.
According to the person in charge of a LED desk lamp factory, "In terms of the wireless charging function of LED desk lamps, fast charging takes 2-3 hours to be full, and slow charging requires 7-8 hours to fill." Undoubtedly, such charging Speed ​​is not attractive to consumers.
3. High cost: The charger needs to have an electronic circuit for driving the wireless coil, and the electrical device needs to have an electronic device for power exchange, and both need a wireless coil, so the cost is higher than direct contact.
At the Hong Kong Spring Lighting Fair, a person in charge of a LED desk lamp told Gao Gong LED that "for export products, the price of LED desk lamps with wireless charging function is 5-6 dollars more than that of ordinary LED desk lamps." Therefore, Gaogong LED also found that the price of LED desk lamps with wireless charging function is generally expensive when investigating wireless charging desk lamps.

4, can not be charged while moving: This problem only occurs on the mobile device, for example, the electric shaver can not be removed from the charger when charging, if the battery in the electric shaver is just completely exhausted, then the electric shaver can not In use, the traditional wire-connected design can be used with the wire connected to the charger.
It is undeniable that charging when not moving is inconvenient for the user. Some users directly said that there is no applicability and it is of little significance.
5, low compatibility: different brands of wireless charging devices because there is no uniform standard, it can not be used interchangeably. At present, the industry has three major alliances of PMA.WPC.A4WP, each implementing different standards. The QI standard implemented by WPC with the largest number of members has already had many products to follow in the world, hoping to achieve standard unification.
Some insiders told Gaogong LED, "There are many mobile wireless charging functions available on the market that have not passed the QI standard. In the process of charging, the battery life of the mobile phone is endangered. Once the mobile phone battery is damaged, these wireless charging. The manufacturer of the product is not responsible."
6, the software is not authorized: wireless charging can be called "black box", and mobile phone software is closely related, once iPhone, Samsung, Huawei and other mobile phone software upgrades, unauthorized wireless charging products can not continue to use. According to Li Zhaohua, "For iPhone8 and iPhonex, the cost of licensing through Apple software is very expensive, and at the current price of LED desk lamps, it is impossible to pay this fee, which forms an intractable" ""."
In addition, some insiders said, "Without the agreement, the wireless charging of the mobile phone will be half-charged, and the power will automatically drop from 7W to about 3W."
In summary, the current wireless charging technology is actually limited to the contact type wireless charging base, which is magnetic resonance or magnetic induction technology, so it is not much different from ordinary wired charging, and still has to be fixed in a certain range. use. Moreover, in terms of the experience of wireless charging, the charging speed is much slower than wired charging, and the charging efficiency is also the biggest obstacle to wireless charging promotion.
It can be seen that even if it is a new function of wireless charging for mobile phones, it is difficult to change the market pattern of LED desk lamps for the time being. It must be said that the LED desk lamp with wireless charging function has a long way to go in the future.
