COB Light Source Price Size

Mentioned at this LED lamp bead light source, the LED light shit light through the control of the built -in micro chip. In the application of small engineering, it can be used without controller, which can achieve gradient, jumping, color flashing, random flashing, the number of work from the chip work And the analysis of the integrated density of the chip found that the integrated packaging multi -chip white light LED knot temperature increased with the increase of the number of integrated chips, and its luminous efficiency was decreased with the increase of the number of integrated chips. It is also an important influencing factor in the application of integrated packaging technology. The steady -state light effect refers to the ratio of the light flux measurement to the electrical power measured when the chip knot temperature is no longer rising and the light strong when the light is strong when the LED light source work enters the thermal stability. The steady -state light effect refers to the optical effects of LED overall lamps except to drive the power supply, which reflects the comprehensive characteristics of light, electricity, and thermal in the actual work of LED. In addition to LED transient light and electrical specialty, the steady -state light effect also includes the temperature changes of system heat transmission and heat dissipation. It is also known as system light. The dynamic effects such as COB light source price gradient alternation can also be achieved through the control of DMX to achieve the effect of chasing, scanning. At present, these main application places are probably these: single buildings, historical building group exterior wall lighting, light and outer light transparency in the building, indoor local lighting, green landscape lighting, advertising card lighting, in addition to volume, LED light source also has a long life span The advantage, this is also the biggest advantage. The bulb attenuation is fast, and although the LED is also attenuated, the speed is slow. In theory, it has a life span of tens of thousands of hours. Life long: LED light source is a new type of electro-optic source. Its working principle is completely different from other existing electro-optical sources. The conversion mechanism is electronics-floor-to-hole composite, belonging to the type of cold light source (non-electrode heating out of light). The LED light source structure is simple, the luminous body is a solid alloy body, coupled with its very small volume, a single LED power, a significant heating, and no problem of fire. LED's service life is significantly higher than the fluorescent lamp tube, which is of great value for reducing maintenance costs. Because LED street lights have lower energy costs and longer service life, more and more cities are adopted. With the arrival of the 5G era, smart LED street lights with a variety of functions have now available. While monitoring traffic and public safety, and showing public information, there is another role in the development of smart cities: 5G base station equipment can be installed in installation. On the lamp post. When the price of COB light source is 10,000 hours, the brightness can reach 70%to 80%of the initial brightness, and the traditional light bulb light source has been replaced twice in this use time. After all Only half of the initial brightness is less than hundreds of products. The product power range ranges from 0.5W to 100W, and the light effect reaches 130lm/W, and zero light decline has achieved 2000 hours. , Products with low requirements for light efficiency. The other end is a high -end product in the dedicated field, such as the limited design space of the lamps, but it requires high -power and high -light general volume output, special trust special requirements, and small hair high -power output. From the middle and long term, the market with an absolutely large proportion of inversion is an inevitable trend. With the light efficiency of the inverted chip, the price is continuously optimized, and the future market space is huge and multi -chip LED integrated packaging is one of the ways to achieve high -power white light LED lighting. This article summarizes the characteristics of integrated packaging, introduced it from the aspects of product application, packaging mode, heat dissipation treatment and optical design, and analyzed the development trend of integrated packaging. , Integrated packaging will also be developed rapidly. COB light sources include red, yellow, blue, green, white, purple light, RGB, etc., which are widely used in fire lights, street lights, miners lights, warning lights, lighting lights, lighting engineering and other aspects. Shenzhen Science and Technology Park has complete management and comfortable environment.
