No matter how they change, the core essence of LED will not change. Through the following basic analysis of LED lamps, we will help you purchase lighting products that meet your budget.The first point: lamp body materialLED must produce heat energy when it converts light energy. Therefore, whether the lamp body needs to dissipate heat requires continuous calculation, and alloy materials are the first choice.Depending on the product type, there is also plastic-coated aluminum, with the main option being all-plastic!ample: LED outdoor landscape lamps are mainly made of AD12 aluminum alloy.LED outdoor projection light floodlights are mainly made of ADC12 aluminum alloy.LED high bay lights are mainly made of AD12 aluminum alloy.LED bulbs are mainly made of plastic-coated aluminum, and low-end bulbs are made of all plastic.LED lamps are mainly made of plastic-coated aluminum, and low-end lamps are made of all plastic.LED lamp tubes are mainly made of PC plastic and low-end all-glass materials.Note: All plastic PCB (light source version), high-end is aluminum substrate, low-end is FR-4 (glass fiber board). Material appearance:Mainly using electrostatic powder baking paint, special sealing and surface coating treatment methods to ensure that the aluminum alloy materials of the lamps are not easy to corrode and rust in harsh environments such as humidity and high temperature.The main surface is anodized and hardened, with a thick texture, pressure resistance and wear resistance. (Mostly aluminum extrusion non-ADC12 die-cast aluminum alloy materials)The appearance is mainly anti-corrosion and anti-rust, but also pays attention to heat dissipation. The lamp body is the most important heat dissipation part of the LED lamp. The heat dissipation effect of the thick lamp body is not better than that of the light and thin material. It mainly depends on the core of the design. Blindly following the thickness will not improve the actual performance. Heat dissipation, but the weight of the lamp body is also a factor that determines the price. ​Second point: LED light-emitting chip chipEach product has different uses and cost-effectiveness, so the level of LED selection is different. To independently select LED light-emitting chips, you can classify them according to the following product characteristics.Example: LED's first imported chips are mainly cost-effective, including OSRAM, PHILIPS, CREE, Citizen, EPISTAR, and SANAN.For outdoor LED landscapes, PHILIPS and CREE are the main ones, and for low-end cost-effectiveness, SANAN is the choice.The main choice for outdoor LED floodlights is EPISTAR, and for low-end cost-effectiveness, choose SANAN.The main LED patio lights are PHILIPS and EPISTAR. For low-end cost-effectiveness, choose SANAN.Indoor LED track lights are mainly OSRAM, PHILIPS, and Citizen. Choose price and warranty based on cost-effectiveness.In the city, LED lamp tubes, LED bulbs, LED panel lamps, LED lamps, LED lamps, LED bracket lamps, and LED ceiling lamps are mainly OSRAM, PHILIPS, and EPISTAR. Choose SANAN for low-end cost-effectiveness.It is ideal to choose chips and chips from big brands. The relative quality is checked according to the process, and the corresponding data is more realistic, such as: luminous flux, lifespan, color temperature, color rendering, heat dissipation ratio, color shift value, blue light content...etc. Buyers can use it with peace of mind!Of course, it depends on the purpose of use and budget. To avoid mistakes, it is recommended to compare multiple sources when purchasing, or choose high-quality products for high-altitude lighting fixtures, and choose cost-effective products for self-replaceable lighting fixtures. The third point is LED driver power supply:What is an LED driving power supply? The LED chip is a semiconductor that needs to provide DC voltage to emit light normally. In order to ensure the long-term stability of the LED chip, it is the most basic requirement of the product. Through the following examples, we can choose a stable LED driving power supply so that the life of the chip can be extended. Greatly improved, it can also reduce the cost of ground maintenance.Example: The first choice for high-power power supply, Taiwan MEAN WELL is mainly used for outdoor LED landscape lights, LED patio lights, LED street lights, LED landscape lights, LED floodlights, LED projection lights...etc.The first choice of dimming/non-dimming power supply for track lighting fixtures is OSRAM, TRIDONIC, PHILIPS..., and secondary MEAN WELL, BOKE... etc.Indoor light sources mainly promote high PF and full voltage (AC85~264V).Note: The power supply has high efficiency, high power factor, cross-current voltage stabilization, surge protection, overheating protection, short circuit protection, overcurrent/overvoltage protection, etc. A good power supply should have the above characteristics to ensure that LED lighting products can be used in various applications. Safe and stable execution in emergencies. Point 4: Lampshade and lens:The milky white lamp cover can achieve a soft and non-glaring atmosphere and a uniform lighting effect, such as LED lamps, LED lamps, LED lamps...etc., which are directly illuminated or within the range of the human eye. On the contrary, the lens gives a strong sense of space and a strong contrast between light and dark. When installed above 3 meters high, the lens can be changed to extend the illumination downwards.Example: It is recommended that indoor light sources have a cover when the height is less than 3 meters, and a lens is recommended when the height is higher than 3 meters.Most low-power outdoor landscape lights are mainly made of transparent or milky white outer lampshades, while high-power and long-distance lights are mainly equipped with projection lenses.Projection for signboards requires a wide angle, while projection for architecture requires a narrow or elliptical angle.Other special application categories require design through simulation.Track lights have special applications, and the angle changes mainly from 15 to 60 degrees.Note: Milky white masks and lenses are mostly made of PC or acrylic, which will reduce the light efficiency by 15%.
