What are the components of LED downlights? From the perspective of lamp body composition, household LED downlights have these main components, such as chips, reflectors, radiators, and driving power supplies. The following is a simple analysis of which parts the LED downlight consists of and how they affect the LED downlight.

Reflective cup composed of LED downlight parts.

The reflector cup carries the secondary light distribution mission of LED lamps and is a very important optical component, which directly affects the light spot effect of a lamp. Lamps without reflectors or with transparent reflectors (mostly traditional lamps) have no secondary light distribution effect. The light source can be seen directly, accompanied by a strong eye-catching sensation, and there will be part of the light on the object. The problem of weakening, or low light transmittance, etc.

LED downlights are particularly special in the planning of the reflector. The design of smooth inner wall reflector + anti-glare surface ring is adopted to improve the utilization rate of luminous flux. The stack of these two kinds of light can get the ideal light use, the light spot is very beautiful, the light is uniform, and there is no yellow halo stray light. Coupled with the new generation of nano-coating technology used in the anti-glare face ring, the light output of the black diamond downlight is uniform and soft, and it has an excellent "deep anti-glare" function.

LED chip composed of LED downlight components.

The light source of LED lamps is a chip, and the price and quality of chips of different brands are very different. Then why do lamps need to choose a good chip? Because this determines whether a lamp can have high luminous efficiency, high color rendering index, and advanced junction temperature advantages. A good lamp is generally expensive in the chip. The defective chip will inevitably affect the life of the lamp.

Driving power source composed of LED downlight components.

The driving power is also a key factor that dominates the life of the lamp. After many lamps become obsolete, the problem seems to be the problem in their own lamp body, but in fact the problem may lie in the driving power supply. The electrolyte inside the defective driving power supply will continue to volatilize over time and under the influence of heat energy, which will premature the premature aging of the lamp. The driving power supply of LED downlights has overcome this problem well. It is always an external power supply (not built-in power supply), separated from the lamp body, high temperature resistance, electrolysis of 105 electrolysis (can work continuously for 8000 hours at a temperature of 105) , The lifespan is 4 times that of the general power supply.

Radiator composed of LED downlight components.

When the lamp is continuously opened, a lot of heat will be generated. If it is not discharged in time, the heat energy accumulated by the lamp will damage the LED chip and various parts, cause light decay, and shorten the service life. This is the mission of the radiator needs to be solved-timely heat removal. Nowadays, the most ideal radiators on the market are "die-casting" (that is, the radiator pressed out by a mold), and the integrated cold forging radiator (made by cold pressing of higher pressure aluminum, which is a new generation High-quality heat dissipation skills). This is 30% higher than the traditional split radiator in terms of heat dissipation (a seamless connection between the aluminum substrate and the radiator, and the heat conduction function is greatly improved), which can ensure a longer life of the LED lamp.
