JMLED Vapor Chamber Test

High-power LED junction temperature on the lamp?

The high-power LED as the higher wattage, used in street lights, patio lights, and so the application of its junction temperature has two elements to be reached at the same time, LED's luminous efficiency and lifetime can be guaranteed. First, the temperature should be balanced, the temperature is not the gap between each single LED that is parallel too large, otherwise cause thermal bias effect, reduced life of the LED, the light fades produce, and finally to the entire light damage. Followed by lower temperatures, if the junction temperature can be maintained at about 75 ℃, the LED's life will be up to the ideal of 50,000 hours.

​Solar Power Systems for LED Street Lighting

JMLED solar street lighting system comes complete with a self-contained Solar power assembly sized to run the specified solar light fixture as per the Requirements set by the customer. Our team designs each system by the power Consumed by the fixture and available sun provided by the geographical location of installation. The battery backup provides a minimum set autonomy for extended Battery life and to take into account local weather conditions.

What is the average temperature board? What helps

The "average temperature plate" simply put, is capable of a lot of heat a small area, fast heat conduction diffusion make concentrate, without damage to the light source elements. After the heat diffusion, needed to reduce the heat flux per unit area several times, you can easily deal with the structure of the heat, which is for high wattage LED, the thermal equilibrium in a centralized way to achieve COB, high-wattage heat flow through the average temperature board to achieve optimum heat, let the LED lamps, has the advantage of high lumens, low light decay, long life.

High-power LED technology maximum threshold (over 60W) of more than that?

Here is two points:
1, if distributed generally due to series-parallel circuit structure, thermal equilibrium problem is a storm. It is also distributed in high wattage lamps insurmountable natural moat, because the heat problem is not only the temperature (Tj level), but also the heat balance of the issue, which is why most of the light plant does not really solve the problem.

2, if centralized, in addition to the problem of the light source substrate, mainly just can not do fast are conduction heat dispersion treatment; this threshold, only the use of L-yu's thermal superconducting technology, in order to overcome complete.

Effect of the biggest problems why LED life?

The biggest problem with the current overall LED technology, only one word hot.

What is the cooling method can solve the current hot?

Centralized source of all good, guide, San technique and structure. Having said that, the only heat the superconducting structure of the company's patented light engine can achieve their goals.

What is the light engine? Why its specifications?

Actually, LED applications, is to use the current system to cut the angle, LED's selection, packaging requirements to guide the heat treatment is in one go. The light engine is the most obscure part of the process of capturing and out the rear light, average temperature, light and other demand components integrated to other lamp factory to apply. Lighting plant only need to heat the structure or lamp structure set up to use the appropriate light engine. Specifications from 80W ~ 150W have, lights, street lights and patio lights can be applied.
