Description
Technical field
The utility model belongs to aircraft docking guidance apparatus field, especially a kind of LED backlight guiding beacon for grating navaid.
Background technology
Aircraft docking guidance equipment is the equipment that a kind of vector aircraft berths, and grating navaid guiding beacon wherein can provide the guiding on left and right directions intuitively for pilot, therefore the backlight of grating navaid guiding beacon needs the orange-yellow light source for high brightness.Backlight of the prior art is fluorescent tube, and fluorescent tube guides the backlight of beacon to have following shortcoming as grating navaid, (1) fluorescent tube glow color is more single, do not have required orange-yellow, need between lamp box and grating, add one deck filter coating, make luminance loss and make complex structure; (2) fluorescent tube is fixed due to the large and shape of single volume, and install can not arrange arbitrarily at lamp box, lamp box non-uniform light, needs between lamp box and grating, add equal tabula rasa and must keep certain distance, causes complex structure and thickness increases; (3) fluorescent tube needs to install ballast, and many fluorescent tubes must fill multiple ballast, not only make cost improve, and device count increases, and adds fault rate, system reliability is declined; (4) grating navaid guides the backlight illumination of beacon to need to regulate, and fluorescent tube, by 220V Alternating Current Power Supply, is not easy to brightness regulation; (5) the fluorescent tube size on market is more fixing, and grating navaid guides beacon change in size is comparatively large according to demand, and existing fluorescent tube size can not meet all demands.If size is not mated, lamp box luminosity can be made more uneven, have a strong impact on raster effects; (6) fluorescent tube luminous efficiency is lower; (7) fluorescent tube is short for service life, easily damages, and General Life is at 2000h to 5000h.
Summary of the invention
It is various that problem to be solved in the utility model is to provide a kind of color, and evenly luminous, volume is little, and energy consumption is low, and reliability is high, applied range, the LED backlight guiding beacon for grating navaid of long service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LED backlight guiding beacon for grating navaid, comprise substrate, LED chip and Switching Power Supply, described substrate-parallel is arranged at grating rear, this substrate is provided with some light source installation cavitys for installing light source assembly towards grating one side, and described substrate back is provided with power supply installation cavity; Described LED chip is arranged in light source installation cavity, and described Switching Power Supply is arranged in power supply installation cavity; Described LED chip is set with lens, and the fixed leg bottom these lens is connected with substrate, and the exiting surface of described lens is set to curved surface; Reflecting plate is provided with between LED chip described in several.
Described reflecting plate is provided with reflecting coating.
Described Switching Power Supply is direct-current switch power supply.
Owing to adopting technique scheme, (1) LED chip glow color is varied, has applicable orange-yellow, can not use filter coating; (2) LED chip single source volume is little, can arrange arbitrarily, and arrangement density can be even, makes lamp box evenly luminous, and do not need to keep certain distance, grating integral thickness can reduce, thus saves installing space; (3) LED chip does not need to install ballast, and only need one piece of Switching Power Supply, structure is simple; (4) LED chip is low-voltage DC supply, and brightness regulation is simple; (5) LED chip can arbitrarily combine the grating meeting any size; (6) energy consumption of same brightness LED chip is 50% to 60% of fluorescent tube, economize energy; (7) the LED chip life-span is at more than 100000h, long service life.
The utility model utilizes LED chip to replace fluorescent tube to guide the backlight of beacon as grating navaid, thus eliminate the parts such as original filter coating, astigmatism plate, ballast, increase by one piece of Switching Power Supply to be used for powering, solve the problem that fluorescent tube produces.
The beneficial effects of the utility model are: have color various, and evenly luminous, volume is little, and energy consumption is low, and reliability is high, applied range, the advantage of long service life.
