How to Choose High -quality LED High -power Lamp Beads--

Teach you how to choose high -quality LED high -power lamp beads: 1. The difference between chip radiation power level: 2. The difference between lamp bead bracket materials: At present, there are aluminum brackets, brass brackets, copper brackets, etc. on the market. Copper brackets are the most expensive, and the price is more than ten times the difference. Even if it is copper bracket, the price of silver plating is divided into high and low. The market is generally called a good bracket, most of which are made of brass silver plating. 3. The difference between the chip size: The size of the chip that is usually reported is MIL. If there is no high -power measurement microscope, it is generally difficult to distinguish. The larger the chip, the brighter the chip. The area of 230 square meters is 230 square meters, and the size of the chip area is a good way to distinguish the size of the chip. 4. The difference between the welding line material: The chip and the bracket use the gold wire welding method to complete the electrode connection. At present, there are two types of alloy lines and pure gold wires on the market. The pure gold line is the best. 1.0, 1.2, etc., the thicker the golden line, the lower the thermal group, the longer the life span. 5. The difference between fluorescence powder: white light beads are made of blue -light chip and yellow fluorescent powder. The fluorescent powder is mainly divided into aluminum acid and silicate. The performance of aluminum acid is better than silicate. It is YAG, YAG has stable performance, low light decay, and poor chemical stability of silicate itself, but the brightness is higher than YAG. If you want to make a product with stable performance, don't be fooled by the so -called high brightness. This is a big problem. 6. The difference between glue: The fluorescent powder should be stirred with glue and on the chip. The quality of the glue will affect light decay and color drift. It is jelly glue. 7. Specifications of color division, separation and splitting: Division: is the color temperature division, such as 3200k-3350K is a gear. The regular packaging factory will provide a color temperature BIN code. Small, good color consistency of light source light. Differential voltage: The voltage of the chip, such as 3.0V-3.15V, is a connection method for the light source, and the voltage is controlled within 0.15V. In this way. Salaring: It is the brightness of the flowing beads of the flowing light beads. There are lumens or shot or light intensity. For the lighting source for lighting, it is best to use the flow distribution. It is recommended that when purchasing high -power LEDs, it is still based on light efficiency. Technology Co., Ltd., specializes. In 13 years of LED component production and sales experience, 1W high -power lamp beads, imitation flow understanding lights are suitable for street lights, watercades, car lights, headlights, etc.; The choice of raw materials, He Li's golden thread, red copper bracket, San'an, Jingxing, Dehao chip. 13 years of industry precipitation to escort your high -quality lamps.
