The difference between led lamp beads and patches

The LED lamp bead is the same as the wick in the patch, but the angle of the lamp bead can be made very small, and its light is concentrated far away, but the irradiation range is limited.  led bulb components，The angle of the patch is generally larger, the light is scattered, and the shot is relatively close, but the irradiation range is relatively wide.


The power of the lamp bead is large, and the power of the patch is small. High-power LED lights generally use 1W high-power LED lamp beads, and low-power LED lights generally use SMD.


Cooling is different. The patch only needs to use the ordinary circuit board, and the natural heat dissipation can achieve a good heat dissipation effect, while the LED lamp bead needs to be equipped with an aluminum heat sink.

How to match the driver of led lights

The driver of the LED lamp is selected according to the operating range of the lamp and the related characteristics of voltage and current. If it is a low-power LED lamp, you only need to choose a simple resistive driver when choosing a driver, ​waterproof led driver ，     but if it is a high-power LED lamp, you need to choose a cross-current driver when choosing a driver. In addition, when choosing a driver for an LED lamp, it is also necessary to choose according to the situation of the lamp bead. It depends on whether the drive current matches the current required across the lamp bead. Generally, when purchasing LED lamps, you can also directly purchase the driver. , all match well. like： ​How to choose a drive that matches a previously used drive ​What to Consider When Choosing an LED Driver  ​led waterproof power supply shell structure

The Significance of Energy Information

  Energy information is an indispensable resource in today's world, playing a crucial role in various sectors, from policy-making and environmental conservation to business strategy and consumer decision-making. As the global community grapples with challenges like climate change, energy security, and sustainable development, the importance of accurate and comprehensive energy information cannot be overstated.   Driving Informed Policy-Making: Governments and regulatory bodies rely heavily on energy information to formulate policies that promote energy efficiency, renewable energy adoption, and emissions reduction. Detailed data on energy production, consumption, and reserves helps policymakers understand current trends and predict future needs. This enables the creation of informed policies that balance economic growth with environmental protection, ensuring a sustainable energy future.   Supporting Business Decisions: For businesses, particularly those in energy-intensive industr

How to divide the IP waterproof level of earphones

How to divide the IP waterproof level of headphones? The IP waterproof level can be divided into 8 levels.  ​Waterproof Wired Earphones ， Let's see how these 8 levels are distinguished? IPX1: stands for vertical dripping, dripping in the vertical direction has no effect, the water flow is 1mm/min, and the test is 10min. IPX2: 15 degrees of water dripping, when the vertical surfaces of the housing are inclined within 15 degrees, the vertical dripping water should have no harmful effect, the water flow is 3mm/min, and each inclined position is 2.5min. IPX3: Each vertical surface is exposed to rain within a range of 60 degrees, without harmful effects, the water flow is 10L/min, and the test time is 10min. IPX4: splashing water, splashing water in all directions of the casing has no effect, each vertical surface is exposed to rain within a range of 180 degrees, the water flow is 10L/min, and the test time is 10min. IPX5: water spray, no effect on the shell in all directions, the water
