Participation 2

Small luminous surface COB

Hongli Zhihui has been committed to the performance improvement of its products. In 2017, Hongli Zhihui made many breakthroughs in the upgrading of COB products, and it is in the forefront of peers in terms of technology and performance.

In October of this year, Hongli Zhihui successfully developed a new product “small luminous surface COB”, which has been introduced to the market. It is reported that this new product is applying for relevant invention patents.

Product main parameters

LM021--Product size 13.5*13.5*1.6mm, luminous surface diameter φ7.5mm, power range 3W~15W;

LM022--Product size 19*19*1.6mm, luminous surface diameter φ10.3mm, power range 12W~30W;

LM023--Product size 19*19*1.6mm, luminous surface diameter φ14.0mm, power range 20W~40W;

LM024--Product size 28*28*1.6mm, luminous surface diameter φ21mm, power range 40W~80W;

The central color temperature is 3000K, and the color rendering index is greater than 80, corresponding to the maximum wattage light effect greater than 90lm/W.

Product technology innovation

1. The light-emitting surface is small, the electric power output per unit light-emitting area can reach 0.35W/mm2, the chip layout is uniform, and the customer lens matching is easier;

2. The phosphor deposition process is used to conduct heat during the phosphor conversion process through the substrate channel;

3, high reliability, high temperature life test (temperature 105 ° C ± 5 ° C), TS point 130 ° C, no blackout phenomenon and luminous flux maintenance rate of 90%.

Market Competitiveness

1. The thickness of the phosphor layer is controlled at 0.15 mm, so that the geometric path of the light in the phosphor layer is shortened, and the uniformity of light emission is better;

2. After the phosphor deposition, the surface temperature of the colloid is lowered by 40 °C compared with the conventional dispensing process, so that the temperature difference of the whole lamp heat dissipation system can be reduced, and the thermal resistance can be reduced by 30%;

3. The phosphor deposition reduces the colloidal temperature, and the product power can be increased by 1.5 times under the same luminous surface;

4. By reducing the light-emitting area by 20%, the illumination angle of the guide light can be reduced to 10°, and the central light intensity can be increased by more than 1.2 times.

Although the "small luminous surface COB" product has been introduced to the market for a short time, with its unique innovation and strong market competitiveness, it has been highly recognized by many customers.

Partial customer evaluation

1. Under the same power, since the light-emitting area is reduced by 20%, the chip layout is more compact. Compared with the conventional products and the series of products, the guide rails are more uniform;

2. The light-emitting area is reduced, so that the light source is closer to the point light source in the optical system of the finished lamp, and the light output of the lamp is more uniform;

3. After the phosphor deposition, the heat of the glue is obviously reduced. After one week of high temperature aging of the lamp, no light decay occurs.

Participation III

filament

The fiery demand for LED filaments has spread from Europe and the United States to Asia, and even in South America and the Middle East, the market has increased significantly, becoming a market sales highlight. In 2017, the global LED filament lamp market is expected to reach 5.66 billion yuan (about 831 million US dollars), an increase of 95% year-on-year; it is expected that CAGR will reach 47.7% from 2017 to 2022.

As far as the current market situation is concerned, although the market prospect of LED filament lamps is very bright, the market penetration rate is not very high at this stage, and promotion has certain difficulties.

However, because the LED filament lighting efficiency is 10 times higher than that of incandescent lamps and saves 10 times of power consumption, Hongli Zhihui is still full of confidence in the LED filament lamp market. In October of this year, Hongli Zhihui once again launched new LED filament products.

At present, Hongli Zhihui LED filament products have been produced normally, and its filament products are applied to different lighting products such as candle lamps and bulb lamps. The products directly dissipate heat through the air, effectively reducing the secondary heat dissipation structure of the lamps, 360° illumination and No need to add a lens. Therefore, LED lamp manufacturers only need to consider the structure of the lamp, which reduces the threshold of the LED lamp factory and reduces the research and development cost of the LED lighting device.

In addition, before the implementation of the project and in the process of technical research and development, Hongli Zhihui collected a large number of relevant domestic and foreign literature materials, looked up the distribution of intellectual property rights related to the project technology, carried out targeted evasion scheme design, and combined with Hongli Zhihui's technical and technological advantages, actively adopting intellectual property protection strategies, has now obtained 2 national invention patents.

Product innovation

1. Design a new type of package structure, and change the horizontal and vertical heat dissipation structure of the prior art into an air heat dissipation structure, and the heat is directly transmitted from the surface of the lamp bead to the air;

2, through reasonable design and special packaging materials, greatly reduce the heat generated by the continuous burning of the lamp beads, can be used in the harsh environment of high temperature and high humidity, and can guarantee the long-lasting luminous flux maintenance rate of the filament products;

3, unique bracket, package structure design, the product has 360 ° light surface, uniform illumination, can meet the high demand of product atmosphere in some occasions, providing a more flexible choice for customer applications.

It is precisely because of the innovative features and strong market competitiveness of LED filament products that the products have been well received by customers once they are introduced to the market.
