This is Blade led headlight which was launched on May 2018. Its double beam led bulb was designed with 24 pcs of SEOUL CSP-Y19 LED CHIPS, while the single beam led bulb was designed with 12 pcs of SEOUL CSP-Y19 LED CHIPS. Take the H11 led bulb single beam as an example, its length is 87.3mm, the width of its heat sink is 32mm. For the bulb body part, the length is 41.9mm and the width is 12.mm.     Besides, the distance between opposing LEDs is 2.54mm, almost equivalent to the filament width of factory halogen bulb, which is 2mm. Generally, its volume is relatively compact compared to others fanless led headlights.     The heat sink of Blade led headlight using 6003 Aluminum alloy, heat sink and bulb body are integrated by the hot pressing process for better heat dissipation, which can’t be disassembled.   LED Bulb Operating Temperature Testing :   Testing the led bulb with 13.5-volt power supplied for 30 minutes and the room temperature is about 25 d...

For the PCB boards now in application to LED headlight, there are mainly four kind of materials, Fiberglass(FR4) PCB, Aluminum PCB, Copper PCB and Ceramic PCB. It is a good deal to understand the distinctions for these four types PCB. Which PCB you choose depends on the circuit design construction of the headlight. FR4 vs. Aluminum PCB   Price Comparison In the cost comparison, the Aluminum PCB is more expensive than FR4, as well as more superior in performance.   Thermally conductivity Aluminum PCB has a great capability of thermal conductivity than FR4 which makes them play an important role in LED lighting technology.   Technology practices The thermal conductivity dielectric material of Aluminum PCB is a thermal bridge that connects the components and metal plate. It can transfer heat to the heat sink through the core automatically. An Aluminum backed PCB is assembled with aluminum backing, highly thermally conductive dielectric layer and the standard circuit lay...

I think many people will meet this situation while shopping two similar products but with a great difference on prices.it is hard to make a choice for you, because you want to purchase the cheaper one but also worry about its quality as well. It is saying that you get what you pay. This is the best description of the current electronic products industry condition in China. Even high-value product like the laptop, or a cheap product like power bank or led light, we can find many similar products from different manufacturers. How can we identify which one is good and which one is in bad quality? We should take the product shell apart to see what kind of electronic component they used inside. In this way, we can understand the reasons why the suppliers always say that the price they offered is the best price and couldn’t be low, while another supplier can casually offer you a price cheaper 5USD, or 10USD. On our last post: How to Identify Genuine G7 or Fake G7 LED Headlight Conversion ...
