The development trend of the technology of LED bulb lamp

     The application of LED in bulb lamp is very extensive, but how to use the lowest cost, design a good performance, good reliability of the ball bubble lamp products, is the challenge for every LED enterprise. In this paper, the development trend of the technology of LED bulb lamp is introduced.
     Because of the long life characteristics of LED, although it is agreed that the integration of LED bulb lamp will be the trend of market development. But because the use of conventional incandescent lamp industry accounted for half of the industry, it can be expected in the next 3 to 5 years time, the E14, E26, E27, B22 LED bulb lamp instead of the traditional incandescent lamp will still occupy a certain market.
     From the trend of the market, the bulb lights will be developed in these ways: Cheaper price, higher light effect, higher reliability and security.
     The minimum luminous efficiency of the US Energy Star requires that the LED bulb is not less than 50lm/W (<10W), and the long-term requirement is 70lm/W. Current market, the majority of products are regular LED lamp factory generally in the light of the 70lm/W.
     Security and reliability are LED's life. However, due to the lack of effective regulation and supervision on the LED market, the safety and reliability of the LED lamps of each enterprise are uneven. The market is filled with a lot of poor quality bulb lights.
     Blind price of the fight to ignore the quality of the product is the root cause of such a high rate of bad products. How to use the lowest cost, design a good performance, good reliability of the ball bubble lamp products, is the challenge for each LED designer.

What are the advantages of LED smart bulbs

     In intelligent lighting, LED smart light bulb has gradually become no longer strange, so what are the advantages of LED smart bulbs?
     LED smart light bulbs four major advantages:
     Remote control. Remote control can be said to be a lot of people choose smart home products a major reason, whether it is now common intelligent water heater, smart air conditioning, or LED smart light bulbs, our control of home appliances has been limited to switches and remote control, through mobile phones or tablet PC APP, we can achieve the light bulb, and brightness adjustment.
     Intelligent monitoring. Through intelligent terminal, we can clearly monitor the operation of home appliances, adjust the lighting brightness, check whether the lights, etc..
     Linkage. The so-called smart home product is a concept of the Internet of things application, smart dimmable LED lamp is not only to stay in their own transformation, but  also can be used with other electrical appliances in the interior. For example, when you send out the instruction which sleeps or makes the movement which sleeps, the lamp can be automatically extinguished, home appliances can enter the silent mode, etc..
     Voice control. Although most of the smart home products have no way to achieve this control effect, but this is also an inevitable direction of the development of smart products and identification of a basis for the mature smart products. The ultimate smart light bulb needs to be able to go beyond the limits of smart phones or tablet computers, direct use of language to operate.

Why the LED bulb light price difference is big

     Different brands of LED ball bubble lamp, even though the same parameters, but the price is a lot of difference, what is the reason causing the difference in the LED bulb light price in the same parameters?
     1. The difference of LED lamp beads. Different quality lamp beads price difference is very large, different types of lamp beads also vary greatly. Some manufacturers in order to reduce the cost, use quality was very poor lamp beads, the luminous decay is very serious for this LED lamp beads, use a few months basically scrapped.
     2. PCB. PCB price difference between different materials is also very large. Such as a square meter of the aluminum substrate about 200~300 yuan, a square meter of FR4 about 150~200 yuan, the most low-end cardboard one square meter only needs a few dozen yuan. Not the same material will have a different effect, the use of cardboard will lead to LED heat can not go out, so as to affect the LED life.
     3. Power Supply. Different types of power prices are not the same, and power price fluctuations is the biggest, the impact on the entire product price is also the biggest. For example, a resistance capacity of the buck power supply only one yuan, but a better switching power supply needs of five or six yuan, and some even want a few dozen  yuan. The influence of power is relatively large on the quality of LED light bulbs, the excellent LED bulb manufacturers will choose the high quality power, poor quality of the power use process prone to failure.
     4. Structure. Different material structure of the price difference is huge, and even the same material structure price is also a lot of difference. Such as plastic structure is completely unable to compare with the metal structure. The same material structure, the public mould and private mould price and a lot of difference. Material quality also affect the product's cooling, more related to the safety of the user.
