Bare crystal package LED photoelectric lighting module

HVLEDs (high voltage LEDs)

The low-voltage LED is used to make the lamp have a difficult situation in the lamp cavity, and it is unrealistic to install a fan, a heat pipe, a semiconductor refrigeration, etc. in the LED lamp, and a non-low-cost solution. The space of the existing indoor lighting fixtures is very small, and it is impossible to place more things. Moreover, the indoor lighting fixtures are highly demanding for the cost performance of the mass consumer electronics products. LED lamps are hot and endless!

The birth of HV LEDs has created a new idea for the design of L ED lighting fixtures. The high voltage and low current of HVLEDs make the LED light source board greatly reduce heat during operation, the temperature of the lamp cavity is lowered, and the LED light source and the lamp are not burned when working. And electrolytic capacitors are no longer short-board; HV LEDs can use the new power supply technology of high-voltage linear segmented constant-current driving chips, thus using a simple driving power supply without a transformer, no heavy inductors, no electrolytic capacitors, and thus HVLEDs lamp beads and rectifiers, drive power chips, resistors, capacitors and other components are attached to the same side of the aluminum substrate or ceramic substrate, suitable for automated mass production, saving labor, further reducing production costs, and facilitating secondary product design of the lamp factory. And production.

Bare crystal package LED photoelectric lighting module

Bare-crystal package LED photoelectric lighting module, perhaps called "photoelectric engine", adhering to the innovative design concept, HVLEDs lamp beads and rectifiers, segmented drive constant current source chips, and resistors and capacitors all attached to the same ceramic substrate Face, as shown in Figure 1. The use of bare LED dies further reduces costs.

The bare-film packaged photoelectric lighting module is a 14W LED photoelectric module. The yellow ring in the ceramic wafer is composed of 18 HV LED lamp beads , and the yellow phosphor powder package is used to form the LED illuminator; the white square in the middle is The alternating current is converted into a direct current rectifier and a segmented driven constant current chip; therefore, the AC alternating current can directly lead to an access point on the ceramic substrate. After the AC AC is connected, the AC is converted into DC by rectification, and the segmented linear driver chip outputs a constant DC power to illuminate the HVLEDs. The thermal measurement point is used to detect the operating temperature of the photovoltaic module board. The insulating and thermal conductivity properties of the ceramic substrate are ideal.

The lamp factory can design and produce N kinds of LED bulbs , downlights, ceiling lamps and other lamps with bare-crystal packaged LED photoelectric lighting modules. By relying on the design strength of the lamp factory, the design and production of ever-changing and distinctive LED lighting Luminaires; the use of standardized optoelectronic lighting modules, both versatile and convenient, can also reduce production costs and inventory risks, more in line with Zhaga's future LED lighting development requirements. Zhaga is an alliance of the world's top LED lighting manufacturers, aiming at standardizing to achieve compatibility and interchangeability of light engines, and to accelerate the widespread use of LED technology. The mission of a forward-looking international standardization organization, Zhaga, is to provide luminaire manufacturers with a better and more efficient solution for light source solutions. The bare-crystal package LED photoelectric lighting module is a novel LED photoelectric engine, representing the future development trend of LED lighting technology, with a strong cost-effective and strong vitality.

It is very easy to assemble LED bulbs with bare-crystal packaged LED illumination optoelectronic modules. As shown in Figure 2, the bare-crystal LED illumination optoelectronic module, plastic-coated aluminum radiator, lampshade, lamp holder, and wire bonding process, A LED bulb can be assembled in minutes.

Designing and producing a new generation of LED lighting fixtures with a new generation of LED photoelectric engines is an inevitable trend in the development of the LED industry.
