Description

LED line lights and LED lighting fixtures

technical field

The invention relates to the field of radiators for LED lamps, in particular to an LED linear lamp and an LED lighting fixture using the LED linear lamp.

Background technique

LED (Light Emitting Diode, light-emitting diode), which can directly and efficiently convert electrical energy into visible light, and has a service life of tens of thousands of hours to 100,000 hours, so it is widely used in landscape, security, special and general lighting and other fields , the market potential is immeasurable.

The basic structure of the LED is a P-N junction of a semiconductor. When the current flows through the LED element, the temperature of the P-N junction will rise, and the temperature of the P-N junction area is called the junction temperature of the LED. It has a very small size, so the temperature of the LED chip is also called the junction temperature of the LED chip.

LED lamps made of LED are known as the most commonly used lighting lamps for their high quality, durability, and energy saving.

However, one disadvantage of LED lamps is that the luminous efficiency of LED lamps is greatly affected by the junction temperature of LEDs. Higher chip junction temperatures will lead to a significant decrease in luminous efficiency and affect the service life of LED lamps. Since the temperature of the LED lamp will continue to rise when it is emitting light, if the heat generated by the LED lamp cannot be dissipated in time during continuous lighting work, it will cause damage to the LED lamp and affect the service life of the LED lamp. Therefore, solving the heat dissipation problem of LED lamps is very important for improving the performance of LED lamps.

In response to the above problems, some LED lamps generally transfer the heat energy generated when the LED emits light directly to aluminum alloy or various metal shells for heat dissipation, or transfer heat energy through heat-conducting silica gel, thereby reducing the high temperature generated by LED lighting, reducing LED light decay, and extending LED lighting service life.

However, for LED lamps with large luminous power, the heat dissipation effect of the shell and the heat conduction effect of the heat-conducting silica gel are poor and cannot meet the heat dissipation requirements, so the high temperature generated during LED lighting cannot be well reduced. If a heat dissipation device is additionally added to the casing, the manufacturing difficulty will be increased, and the cost will be higher.
