LED light fixtures are now a common fixture in many homes and businesses, so we'll briefly introduce you to some of the main components of led light fixtures. The main components of LED lighting fixtures devices are: LED light-emitting diodes, PCB circuit boards and housings.
1. LED light-emitting diodes
The brightness of a light emitting diode is determined by the brightness of the bare core of the LED chip and the shape of the lamp body package, its lifetime is determined by the LED.
The working environment and quality of the LED chip determines its lifetime. A special note here is that the standard size of LED wafers used in LED lighting products is now generally 12 mil for red and yellow, 14 mil for blue and green, but 8-10 mil wafers are also used. Different sizes of wafers can have the same luminous brightness, but their lifetimes are completely different.
2. PCB circuit boards
The circuit board as the carrier of the light source directly affects the life and failure rate of the luminaire. All electronic circuits of LED lighting fixtures circuit are on the PCB circuit board, its material and processing will directly affect the quality and life of the product. The circuit board material is divided into The standard material for LED lighting products should be full glass fibre double panel.
3. Housing
The housing, as the light mixing and protective layer of the LED lighting fixture, also affects the effect and life of the LED lighting fixture. The engineering material used nowadays is generally PC (polycarbonate), which is the best in terms of ageing resistance, UV protection and impact resistance. Also available in PMMA (acrylic), which is a little less weather resistant and more brittle and fragile. The PC material itself is colourless and can be processed in different colours by adding different colouring agents as required. PC tubes are generally used in clear and milky white. Transparent tubes are brighter than opalescent tubes, but opalescent tubes are better at mixing colours than transparent tubes. In addition to this, there are also aluminium, aluminium alloy, iron, ABS and other materials.
In detail, LED lamps are divided into the following components: light sources, circuit boards, heat sinks, power supplies, thermally conductive silicone grease (used for bonding between lamp beads and circuit boards and circuit boards and heat sinks for thermal conductivity), secondary light distribution materials, and lamp housings.
