LED light group structure

The present invention relates to an LED lamp group structure, in particular to a lamp and a lamp holder using a light-emitting diode (LED) as a light source, in particular to a light-emitting diode unit and a driver of the lamp, and a frame of the lamp.

With the rapid development of technology, the production technology of Light-Emitting Diode (LED) has made long-term progress. It has the advantages of small size, light weight, no pollution, energy saving and long service life, which makes the application of LED increasingly diverse. It gradually replaces the fluorescent tubes used in daily life. Like fluorescent tubes, LED luminaires are also mounted on the base.

Most of the traditional LED lamps are made into the shape of a lamp tube, a light bar or a light bulb. Among them, the LED lamp of the lamp type and the light bar type are mainly arranged with a plurality of LEDs on the same side of a strip-shaped circuit board. And a power line electrically connecting each LED is disposed on the circuit board, and the connector is connected to a connector (Lighter) to be installed in the LED socket.

The traditional LED lamp holder is provided with an external LED power driver (LED Driver), which is a power adjustment electronic device capable of driving the LED illumination unit to operate normally, has the function of converting AC power into DC power, and adjusting the power supply. The voltage, current and frequency and other electrical specifications make the electrical specifications of the power supply match the LED lighting unit to drive the LED lighting unit to be normal. Operation. If the electrical specifications of the power supply do not match the LED lighting unit, it is easy to cause the LED lighting unit to operate abnormally, cannot operate, or even burn out.

When the circuit board of the foregoing conventional LED lighting unit is installed in the lamp holder, the connector of the circuit board can be plugged into the connector of the LED driver, so that the external power source is supplied to the circuit board via the LED driver and the connector to drive the LED to emit light. . However, the disadvantage is that since the LED driver is disposed in the lamp holder, when the LED lighting unit in the lamp holder is damaged, only the LED lighting unit conforming to the electrical specifications of the LED driver in the lamp holder can be replaced, which causes inconvenience in use.

In addition, when installing a conventional LED lighting unit, it is conventional to direct the LED on the board toward the direction in which the light is to be illuminated. For example, when the lamp holder is set on the ceiling, the LED of the circuit board will project light to the lower area of the ceiling; however, the light in front of the LED lighting unit will be too bright, and the surrounding area will be dim, and the LED will be emitted. The light is difficult to diffuse to the back surface area of the circuit board, so the effect of the reflective surface of the inner wall of the conventional lamp holder to enhance the peripheral brightness through reflection is not obvious.

The reason is that since the light emitted by the LED is a direct-light source, the illumination angle is about 20 degrees. When it is actually applied to the illumination of the lamp, it is often limited by the widest illumination angle of the LED itself, and cannot be effectively applied. The range of ray casting in the environment.

Therefore, the main purpose of this creation is to provide an LED lamp group structure, which can be integrated with the driver and the driver in the lamp, so that the driver is mounted on the lamp holder with the lamp, so as to avoid the driver and the lamp in the lamp holder.

Since the LED driver is disposed inside the frame, the LED driver can be replaced or replaced with the LED lamp, and the LED lamp is replaced. When it is not necessary to compare the electrical specifications of the LED driver in the lamp holder and the LED in the lamp, it is quite convenient to use. In addition, the LED light-emitting unit is placed on the side of the frame, so that the light emitted by the LED light-emitting unit is projected toward the side of the frame, which is beneficial to generate uniform light by the reflection of the external lamp holder, thereby improving the overall ambient light.
