As a lighting source, LED has been widely used in many fields, including landscape lighting market, automobile market, traffic light market, special general lighting, security lighting and special lighting, etc. So what should we pay attention to when buying lamps? We focus on brightness, so how can we spend the least amount of money to buy more brightness? Let's analyze how to buy the brightest lamp from the aspects of price and material.
First of all, the cheap ones must be done with materials and craftsmanship. The price is naturally much cheaper. The inferior materials make the performance worse, and the energy saving effect cannot be better achieved. Take 9-watt LED bulbs as an example, the price of 9-watt LED bulbs with slightly better quality may be between 30-40 yuan, while the inferior ones may be bought for more than 10 yuan, and even a few yuan, not to mention It is said that there is also free shipping..., let's analyze the difference between them:
What do we buy lamps for? Can be answered in this way, light and service. The first is light. How can we buy more light with less money? Here we need to measure the price/performance ratio of lamps. Usually lamp manufacturers will have a light efficiency of 120lm/W. As I said in the previous paragraph, I will not repeat them here The second is service. Service includes pre-sale service and after-sale service. Pre-sale includes the needs put forward by consumers. Can manufacturers provide complete solutions? Lighting optical design is a great knowledge. Are the lamps provided? Satisfying the lighting needs of consumers, including the production technology of lamps and lanterns before sales, it is said that details determine success or failure. The production of high-quality lamps should have many details such as light decay test, anti-static, high and low temperature resistance, pressure resistance, aging, etc. Defective lamps and lanterns will definitely save a lot of important technology because the quotation should be kept very low. Including the training of production workers and the details of the production process, it takes a lot of time and energy to gradually improve. Then there is the after-sales service. After-sales service is usually the quality assurance and protection of lamps and lanterns. When it comes to the issue of quality assurance, it has to be related to the raw materials. The quality of the power supply and lamp beads is what determines the product warranty time, and it is composed of defective components. After the power supply has been powered on for a long time, the function will be unstable, or even broken, so that the lamps cannot be used normally, and then there is no long-term warranty. Therefore, many defective lamps on the market will have a quality of one year. After-sales also includes whether the problems encountered in the later use of lamps can be solved.
Generally, the luminous efficiency of high-quality LEDs can reach 130-140lm/W, and the luminous flux of 9 watts of LED lamps is about 1200lm. . Taking the general energy-saving lamp 60lm/W as a reference, the general energy-saving lamp flux is 1200lm. According to the average light efficiency, high-quality 9-watt bulbs can replace the usual energy-saving lamps with 20 watts. LED bulbs cannot completely replace 20-watt ordinary energy-saving lamps, only by increasing the power can they be replaced, which will not save energy. We want to replace the ordinary energy-saving lamps with LEDs because of the energy-saving of LEDs. When buying defective lamps, the light we buy is not energy-saving. In the above example, it can be seen that under the same power consumption, the announced light It is not the same and the light decays quickly. The luminous flux of the purchased lamps is different, and the effect of energy saving cannot be achieved, so it is meaningless to replace.
Therefore, no company can create high-efficiency and energy-saving lamps at a very low price. The purpose of opening a company is to make money. If the price is so low that the cost is unbearable, then it can only do this business or use inferior products. material instead. Therefore, we still buy relatively high cost performance, do not blindly pursue low prices, if a low-quality light bulb of 15 yuan that cannot save energy can only be used for one year, but a high-quality light bulb of 30 yuan can be used for three years and is very good for users. Save on electricity bills, everyone is savvy and can figure out the difference and pros and cons between the two options.
