COB light source black horse TOYONIA-----YOLL HR series Y3K depth analysis

TOYONIA has adopted a solid marketing route in the Chinese market, without a lot of promotional activities, and strict control of distribution channels. TOYONIA's professional-grade YOLL MD series COB light source is not sold in the domestic market. It is understood that YOLL MD series COB light source is packaged in gold-free wire, with CRI reaching 99, R9 reaching 99.9, and luminous efficacy reaching 99 (lm/w). The parameters of the limit are enough to stand out from the crowd and lay the status of the rivers and lakes.

What is the performance of TOYONIA products? Now take the YOLL HR series Y3K model as an example to analyze its parameters in depth.

First, the basic parameters:

Second, the light effect and the center light intensity:

Y3K (CCT: 3000K) At a recommended current of 750mA, the VF is 36V, and the measured light efficiency is 92lm/w, which may be affected by the test conditions, which is slightly lower than the official data of 98 lm/w. Under the same test conditions, Y3K (CCT: 3000K) has a VF of 36.5V at 850mA, a luminous efficiency of 85lm/w, a CREE CXA1520 (CCT:3000K) VF of 39.1V, and a luminous efficacy of 82lm/w. TOYONIA Y3K is slightly higher.

Y3K (CCT: 5000K) matches the 10D reflector (measured beam angle 10.8D) at a recommended current of 750mA, and the center intensity is 32800cd. From this, it is estimated that the center light intensity can reach 40,000 cd at a current of 900 mA.

Under the same test conditions (CCT: 5000K, beam angle measured 10.8~11D), when Y3K drives 500mA, the VF is 35.2V, the light source power is 17.6W, and the central light intensity can reach 23000cd, using a well-known brand patch lamp. The PAR30 (35W) center intensity is 21600 cd. Under the premise that the same beam angle and power difference are nearly doubled, the Y3K center light intensity as a COB light source can exceed the higher-efficiency patch lamp bead PAR30, which is admirable.

Summary: The TOYONIA Y3K is packaged in a high-density package with high-density beam output characteristics that reduce light loss. When the same lighting effect is reached, the power of the lamp is greatly reduced, and the volume of the lamp is reduced.

Third, reliability:

The traditional COB adopts a gold wire connection package, and the light-emitting surface is pressed by an external force, which easily damages the gold wire. When the use temperature is too high, the colloid expands and shrinks and breaks the gold wire. Easy to die is the most troublesome thing in traditional COB applications.

Y3K adopts a gold-free package structure, which fundamentally solves the problem of dead lights caused by broken gold wires, so that the application temperature of COB light source can be increased upwards, and Y3K allows TC point temperature to reach 100 °C. The Y3K substrate is made of a material with extremely fast thermal conductivity, so that it is difficult to solder the connecting wire by the ordinary wire bonding process (this phenomenon also exists on the CREE CXA1520). This structure can quickly derive the heat of the light source chip, ensuring stable performance when the light source is working.

Summary: TOYONIA Y3K adopts gold-free wire encapsulation mode, which can quickly conduct heat and heat, and at the same time increase the upper limit of the use temperature of the light source, and the physical strength and reliability of use are much higher than the traditional COB light source. The probability of dead light caused by external force and temperature is greatly reduced.

Fourth, light color:

TOYONIA Y3K uses 2-step binning, which has reached the limit in the industry. Many well-known brands now use 3-step binning, and domestic packaging companies are in 4-step or 6-step.

V. Price:

The current market price of TOYONIA Y3K is around 25 yuan. The actual price is not known. Although this price positioning has not brought much surprise to the application market, it also reduces the threshold for high-end COB light source application.

Sixth, summary:

In summary, TOYONIA YOLL HR series Y3K COB adopts advanced high-density gold-free packaging technology, which has high comprehensive performance and cost performance. Compared with the CERR CXA 1520, the performance of the CXA1520 has a slight advantage, and the Y3K is slightly better than the price.

Expect to have access to the TOYONIA professional YOLL MD series COB light source products, and experience the ultimate light color of the light source under the data of CRI/99, R9/99.9, and light effect/99.
