From the early low-power power indicator and mobile phone key source, it has progressed to lED backlight modules and general lighting products with low power consumption, long life and high color rendering. At present, only 20% of the input power of high-power LEDs is converted into light, and the remaining 8〇% is converted into heat. When the LED heat source cannot be effectively exported, the LED interface temperature (Juncti〇n Temperature) will increase, which will affect the output efficiency of the light, which in turn will reduce the luminous efficiency and lifetime. For this reason, there is a so-called LED light bar, which is mainly designed to provide energy-saving lighting. (4) The above-mentioned heat dissipation problem cannot be solved, so it can only be used with low-power LEDs. For the structure, please refer to the ninth' The figure 10 is mainly composed of a strip casing (4〇) and a circuit board (50), and the casing includes a back plate (41), an upper plate (42) disposed at an upper and lower ends of the back plate (4), and The lower plate (43) has a shape in which the outer casing (4 turns) is formed in a side view, and the front end thereof is open, and the circuit board (5 turns) is provided with a plurality of light emitting diodes (51). The circuit board (50) is disposed on the open end of the outer casing (4Q), and the two ends of the outer casing (4〇) 3 «/4530 are respectively provided with a fixing seat (60) for mounting and fixing the light bar. When the LED light bar provides illumination, part of the light emitting diode (51) can be concentrated on the circuit board (5〇), but the outer casing _ is closed after the mounting circuit board _, so the circuit board The thermal energy on (50) cannot be effectively dissipated, and in order to avoid the light decay caused by the overheating of the light-emitting diode (51), only the lower power components can be selected. From the above, it is known that there is a problem with the strips of light strips. The problem remains to be further reviewed and a viable solution is sought. ^ [New Content] Therefore, the main purpose of this creation is to provide an LED light bar with an ideal heat dissipation effect, so that the waste heat generated during illumination can be effectively eliminated, and the light fading of the lamp is not caused by overheating.

Since the LED strip is formed by using a vent structure on at least one side of the lamp holder for heat dissipation, when the LED strip provides illumination, the heat generated by the LED module is still concentrated on the circuit board, but on the circuit board. The heat energy can be dissipated by the airflow entering through the vent, so that the light-emitting diode module does not cause light decay due to overheating; and because the heat dissipation problem is solved, the light-emitting diode module can be used in a small amount and the power is relatively low.
