New led billboard lights
What are LED Billboard lights?
LED Billboard lights are specialized flood lights with optics designed to light up a billboard from a top or bottom placement. What makes these lights special is the optics that have been developed to accomplish this. Creating an optimal lighting pattern from only a few short feet away from the bill board requires engineering, And LED Billboard lights deliver.
What are LED?
LED can directly convert electricity into Light. The heart of an LED lamp is an LED, and the heart of an LED is a semiconductor LED chip. LED(Light-Emitting Diode in Chinese) is a semiconductor that can convert electrical energy into visible Light. It changes the principle of tungsten filament luminescence of incandescent lamp and three basic color powder luminescence of energy saving lamp, and uses electric field luminescence.
According to the analysis, LED features are very obvious, long life, high light efficiency, no radiation and low power consumption. Compared with ordinary incandescent lamp, spiral energy-saving lamp and T5 three-color fluorescent lamp, the results show that the light efficiency of ordinary incandescent lamp is 121m/W and the life is less than 2000 hours, the light efficiency of spiral energy-saving lamp is 601m/W and the life is less than 8000 hours, and the light efficiency of T5 fluorescent lamp is 961m/W. The lifespan is about 10,000 hours, while the light efficiency of a white LED with a diameter of 5 mm can exceed 1501m/W, and the lifespan can be greater than 100,000 hours.
Disadvantages of existing LED billboard lights
Some people predict that the future LED life limit will be infinite. High power refers to high luminous power, generally 0.5W, 1W, 3W, 5W or higher. Light intensity and lumen is larger than small power, but the same heat dissipation is also very large, the existing high-power LED advertising lights are single application, need to add a large heat sink, resulting in the lamp volume is too large, heavy weight.
Reduce the size of the heat sink, will cause bad heat dissipation, will lead to LED service life attenuation, brightness reduction, or even less than the normal lighting and optical effect, at the same time, the existing LED advertising lamp waterproof performance and dustproof performance is poor, it is difficult to ensure that the front and back of the LED advertising lamp has the same illumination intensity and exposure range.
Advantages of the New LED billboard lights
New LED billboard lights, can improve the heat dissipation performance, waterproof and dustproof performance and exposure range. The new LED billboard lights is characterized in that it comprises a heat dissipation shell and an LED lamp board installed in the heat dissipation shell.
Among them, the two relative side walls of the heat dissipation shell are provided with through holes, LED lamp board comprises a printed circuit board, the front and back of the printed circuit board are installed with LED lamp beads, the LED lamp beads are respectively covered with an optical lens, the optical lens and the printed circuit board phase is fixed, and the optical lens is exposed in the radiator through hole.
The two relative side walls of the heat dissipation shell are respectively provided with three through holes, and the front and back of the printed circuit board are respectively provided with three LED lamp beads.The printed circuit board is connected to an insulated wire that extends out of the heat dissipation case. The material of the heat dissipation shell is plastic.
New LED billboard lights beneficial effects of advertising is using a new type of optical lens set directly on the printed circuit boards, LED lamp bead quilt in optical lens, changed the existing technology of optical lens is installed on the shell structure, improve the performance of LED billboard lights waterproof and dustproof performance, adopts cooling case at the same time, can improve the heat performance of LED billboard lights, And the front and back of the printed circuit board are installed with LED lamp beads, so that the front and back of the LED lamp have the same illumination intensity and exposure range.
