The basic classification of LED panel light information varieties

LED panel light information varieties are very rich, but can be basically divided into three categories: LED panel light information 1: For LED panel lights made of 2835/4014 patch low-power LED, the power supply is also generally adopted resistance and capacitance buck circuit, and some LED panel light manufacturers use constant current circuit. Compared with straw hat LED, the patch LED dissipated heat slightly better, and it has a heat-conducting substrate, which can export part of heat in combination with aluminum substrate. Another LED panel light information is revealed. Due to the neglected LED heat, many medium power patch LED panel lights, without heat sink, still use plastic shell, and the light failure is still serious. The low end power supply with resistance and capacitance step-down is adopted. Due to the unstable voltage of the grid, the current fluctuates and the brightness fluctuates, the price is moderate and the quality is slightly better. LED panel light information two, by the power strips made of LED panel light, LED constant current power supply adopt isolation circuit, with a constant current, such as 1 w leds, usually takes 6 1 watt LED chips, series, using constant current 300 ma current source power supply, wide input voltage power, make the power grid volatility, current there is no change, The luminous flux, that is, brightness, is kept constant. Six patch leds are welded on the aluminum substrate, and the aluminum substrate is combined with the radiator. The heat can be dissipated promptly and quickly to ensure that the temperature of the LED chip is lower than the allowed junction temperature of the LED, so as to ensure the real effective life of the LED panel lamp. This kind of LED panel light has high price and good quality, which is also the development direction of LED panel light. LED panel light information 3: LED energy-saving lamp made of straw hat type low-power LED, power supply adopts resistance capacitance step-down circuit. Straw hat LED extends the packaging form of indicator LED and epoxy resin packaging, which makes the LED chip unable to dissipate heat, and the light failure is serious. Many white LED, after using for a period of time, the color temperature becomes high, gradually becomes blue and dim. There are also manufacturers committed to the development of low light decay straw hat LED, but because there is no change in the form of packaging, light decay is still not a big change. This kind of LED panel light products are transitional products with low price and poor quality. In fact, LED panel light information and a lot of knowledge, if consumers want to buy, we must understand its performance and use environment, so as to buy the most satisfactory products.
