1. It's better to look at the component, if the 100W component of the same level is enough, whether the shell is made of enough materials, the thickness of the heat sink and the individual length, if the thickness is large and long, it's better. Heat dissipation design, heat dissipation material, 6063 aviation aluminum is the best choice. It is not only beautiful in appearance, but also powerful in heat dissipation capacity. Pay attention to observe whether the heat sink has corresponding thickness and surface area. Since the heat is mainly dissipated from the heat sink, the heat sink is very important. The three basic ways of heat dissipation technology and heat transfer are conduction, convection and radiation. The heat treatment is divided into transient analysis and steady-state analysis from these three aspects. High power LED is widely used in lighting. At present, the light efficiency of commercial high-power LED is only 15% ~ 30%, and most of the rest energy is converted into heat energy. If the heat energy can not be effectively discharged, it will lead to very serious consequences. So we must pay attention to heat dissipation when designing the shell. In the purchase, we try to choose all aluminum structure, aluminum has better heat dissipation, but aluminum alloy heat dissipation is a little unsatisfactory.
2. According to the wattage, some manufacturers of 100W can't do this high, maybe only 50W or 75W, commonly known as 0.5W and 0.75w. To test the power, just buy a multimeter to actually measure it.
3. The quality and size of the light source chip. In order to reduce the cost and improve the competitiveness, manufacturers use low-quality and insufficient w lamp beads. Under the seller's deception, you can figure out that the number of integrated lamp beads is indeed enough. There are so many chips in it, but the size is very small and the brightness is very low. This kind of phenomenon is often called short weight, but some consumers can't find it without professional tools. 3. It is not easy to enter water if the sealing is good, that is to say, the waterproof performance is good. As long as the lamp shell is good and the good sealing strip is added, it must be above IP65. It is recommended to use professional lamps in the water, such as underwater lamps, underground lamps, etc., which are tightly sealed.
4. Look at the power supply. It may be disassembled to look at the power supply. In order to save costs, some manufacturers do not add a waterproof epoxy resin into the power supply, so there are good ones. Power quality, small lamp beads, constant current source output current is also small. Constant current source is composed of many electronic parts. Generally, the manufacturer shall purchase at least several hundred thousand pieces of each component at a time. After assembly, it shall be aged and tested on imported equipment. Each constant current source shall be tested at high and low temperature to eliminate unqualified components. Regular manufacturers will not produce such inferior constant current source. LED lamps must be equipped with high quality and high efficiency driving power. The service life of the power supply directly affects the overall service life of the luminaire. Consult the manufacturer about various driving parameters, such as output voltage and current, working temperature, etc. The power supply of the floodlight is to be filled with glue and water-proof. We have even seen some manufacturers cheat consumers in the power supply. Take the 30W LED power supply for example, there are more than 10 pieces, and there are also more than 30 pieces. In fact, there are many famous ones. 5. According to the process, the quality of the whole lamp is related to the use of power supply, light source, sealing strip, cable thickness, heat-conducting silicone grease, the workers' process level (care, welding process), and the workers in small workshops do not wash their hands, let alone those anti-static clothes.
The above questions are about the quality problems and maintenance methods of the floodlight. If you need to know more or consult the relevant questions, you can contact the editor. It is recommended to use the LED outdoor lamps of Zhongshan Zhuopu Lighting Technology Co., Ltd. because Zhuopu lighting is a manufacturer specializing in the production of LED outdoor view lighting lamps.
