Introduction to the bubble:LED bulb LED bulb is a new energy-saving lamp to replace the traditional incandescent bulb. Traditional incandescent lamp (tungsten lamp), high energy consumption, short service life, in the global resource environment and has gradually be governments it is prohibited to produce, then substitute products is electronic energy-saving lamps, electronic energy-saving lamp is more energy saving effect, but due to use a lot of environmental pollution by heavy metals, and contrary to the trend of environmental protection. With the rapid development of LED technology, LED lighting has gradually become the choice of new green lighting. LED is far superior to traditional lighting products in luminous principle, energy saving and environmental protection.Birth Background:Because incandescent lamp and electronic energy-saving lamps in People's Daily use still occupies a very high proportion, in order to reduce the waste, LED lighting manufacturers must develop in accordance with the existing interface and habits of the people are using the LED lighting products, people don't need to replace the original traditional lamps and lanterns pedestal and lines can be used under the condition of a new generation of LED lighting products. So the LED bulb came into being.Technical Features:LED bulb adopts the existing interface mode, namely screw and socket mode (E26\E27\E14\B22, etc.), and even imitated the shape of incandescent bulb in order to meet people's use habits. Based on the principle of LED unidirectional luminescence, designers have changed the lamp structure so that the light distribution curve of LED bulb is basically similar to the point light source of incandescent lamp. Based on the luminescence characteristics of LED, the structure of LED bulb is more complex than incandescent lamp, which is basically divided into light source, drive circuit and heat dissipation device. Only by the cooperation of these parts can we create LED bulb products with low energy consumption, lon

1.  energy savingWith the rapid development of LED lighting technology, the energy-saving effect of LED bulb has reached a very high degree. Under the same light efficiency, the energy consumption has been reduced to 1/8 of the incandescent lamp and 1/2 of the electronic energy-saving lamp. Therefore, it is an inevitable trend that LED lighting products replace the current traditional lighting products.2. priceLED bulb structure is more complex than incandescent lamp, so even in the case of mass production, the product price will be higher than incandescent lamp, at present, LED bulb price is also higher than electronic energy-saving lamp. But as more and more people become aware and accept it, and mass production slowly rolls out, the price of LED bulbs will soon reach the level of electronic energy-saving lamps. Even at today's higher prices, the initial purchase cost plus one year of electricity is less than incandescents and CFLS on a one-year basis, if you factor in the savings at the time of purchase. The LED bulb has a service life of up to 30,000 hours.3. Product featuresLow current, low voltage, small size, light weightSingle LED electrical characteristics: DC3.5V, 350mAEnergy saving to achieve the goal of 75-90%, high efficiency, low energy consumptionExcellent electrical performance, monochrome line, good color renderingNo heat, no burn black lampshade, environmental protection and beautiful, belongs to the green lighting sourceLife expectancy is 40,000 hoursWith good protection function: short circuit protection, no-load protection, over temperature protection, overload protection

LED lighting lamps are more and more popular, and LED lighting lamps competition is more and more fierce, LED lighting lamps gradually develop into a lighting trend. With the gradual growth of LED lighting energy-saving lamp industry, LED lighting price war is increasingly fierce, LED lighting in the appearance, structure, function of almost the same situation, the price difference is 2, 3 times; Also, there are thousands of LED lighting manufacturers now, which is really have technology, strength is not easy to distinguish, the LED lighting is difficult to distinguish the quality. In the LED lighting market is so chaotic, how to choose better LED lighting with higher cost performance requires the majority of consumers to understand some factors affecting the cost performance of LED lighting lamps, such as the following 8 points affecting the cost performance of LED lighting lamps:1, LED lighting life: different quality OF LED energy-saving lamps is the key to life, life is determined by LED light source decline. LED light source low light decay, long life, LED lighting lamps and lanterns high price.2, LED chip: LED lighting lamp core part of LED light body LED chip, different LED chips, the price difference is very large. LED chips from Japan and the United States are better and more expensive, while LED chips from Taiwan and Local Chinese manufacturers are slightly cheaper. At the same time to see LED chip size, LED price is proportional to the size of LED chip, the quality of large chip LED is better than small chip.3, LED packaging colloidal: general LED colloidal epoxy resin, plus uv resistance and fire retardant LED price is more expensive, high-quality outdoor LED lighting should be uv resistance and fire prevention.4, LED brightness: LED brightness, the price is different. Leds used in LEled lighting fixtures should meet the Laser Class I standard.5, LED antistatic ability: antistatic ability of LED, long life, so the price is high. Usually more than 700V antistatic LED can be used for

What are Bubbles and vacuum Bubbles (Bubbles) defects?Bubbles and vacuum Bubbles (Bubbles) defects, because the center of the wall thickness of the product cooling is the slowest, the surface of the product cooling rapidly, the rapidly shrinking surface will pull the material over, the uneven volume of the molding product shrinkage caused by the thickness of the part of the hole, the water or gas in the plastic bubble becomes a bubble. Bubbles can be divided into bubbles and vacuum bubbles. Generally speaking, bubbles occurring on transparent products can be directly observed, while bubbles occurring on opaque products can sometimes not be seen from the outside and can only be found by cutting them open or other means. The appearance of bubbles will make the product filled, uneven surface. As shown in figure: Bubble and vacuum bubble (Bubbles) defect analysis and elimination method1) Improper control of forming conditionsMany technological parameters have a direct effect on the formation of bubbles and vacuum bubbles. If the injection pressure is too low, the injection speed is too fast, the injection time and cycle are too short, the amount of feed is too much or too little, the pressure holding is insufficient, the cooling is not uniform or insufficient, and the material temperature and mold temperature control is improper, will cause bubbles in the plastic parts. Especially when high-speed injection, the gas in the mold can not be discharged, resulting in too much residual gas in the molten material. Therefore, the injection speed should be appropriately reduced. However, if the speed drops too much and the injection pressure is too low, it is difficult to exhaust the gas in the molten material, and it is easy to produce bubbles, depressions and underinjection. Therefore, the injection speed and pressure should be adjusted with special caution. In addition, bubbles and vacuum bubbles can be avoided by adjusting the injection and pressure holding time, improving the cooling conditions and controllin

Pay attention to the service life of LED energy-saving lamps. LED energy-saving lamps, service life is long, but affected by factors such as environment, droop, LED energy-saving lamp life is affected, must know the factory when purchasing LED bulbs with LED energy-saving lighting failure and service life, good quality, light failure is small, long service life, the price will be high.
