1. The choice of light source

  At present, the well-known brands of LED light sources originate from the United States and Germany (the specific brands are inconvenient to indicate in this chapter, so as not to cause bias when browsing, I believe many users are also aware of it), and the LED light source in Taiwan, China, the chip technology has also developed earlier and better. Chip manufacturers represented by Shenzhen are blooming everywhere. Due to the difference in luminous flux, light decay, color rendering, and weather resistance, the prices of chips of different brands are often several times different. For example, a brand in Germany and a brand in Shenzhen, the packaged chips with the same power, that is, LED lamp beads, the price can be There is a tenfold difference.

2. Application of power scheme

A good power supply can guarantee the service life of the lamps. Everyone knows that the LED light source has a long life and can be lit for 100,000 hours. A good power supply can guarantee the service life of the lamps. The mismatch of the power supply scheme can also make the LED light source of the international famous brand can only be used for half a year and a year. In the end, either the light decay is too large or the power supply is blind, so the application of the power supply is very important in high-end lamps and lanterns.

3. Design of heat dissipation structure

    Temperature rise is an important criterion used to measure a professional LED lighting product. If the temperature rise is too high, if the LED lamp bead is placed in a high temperature environment for a long time, the life of the chip will be greatly reduced. A good temperature rise should be kept within 30 degrees. If the ambient temperature is 25 degrees, the temperature of the lamp should not exceed 50 degrees. To control a good temperature rise, in addition to a good thermal conductivity structure, there must be enough heat dissipation surfaces to achieve heat dissipation.

    Many advertised first-class lighting products can be seen in terms of power. If a product with a power of 200W is only A4 in size, and the egg shell is used as a dojo, how can there be good heat conduction and heat dissipation? .

    Therefore, when designing and developing products for truly high-quality LED lamps, the thermal conductivity and heat dissipation structure of the products will be fully planned, and a margin should be reserved. In terms of the temperature rise of explosion-proof LED floodlights, LED explosion-proof platform lamps and other series products No more than 25 degrees, that's the principle.

To sum up, the various doorways of LED lighting products that are simple but not simple determine the cost of this product, which also determines the pricing. In real sales, we will also encounter some manufacturers that use weight and power to set prices. It can be said that this is pure nonsense. Because the products used in different places have different layouts, the required structures are also quite different. Simply using power to price will only mislead users and damage the entire industry.
