Abstract
The utility model relates to the light source technology field, in particular to a nuclear radio-resistant light projecting lamp. The light source of the lamp adopts a double-tungsten wire tungsten halogen lamp with power range from 1000W-1800W, the lamp comprises a casing, a luminous source holder, a front light-penetrated shade, and a reflector, wherein the luminous source is fixed in the casing through holders at the two ends thereof, a front light-penetrated shade is equipped on the front port of the casing, and the edge of the reflector with an arc-type lateral section is immobilized on the side wall of the casing. The utility model satisfies the requirements of 'nuclear illuminator underwater' that the illumination is higher than 1600 Lx at one-meter depth with evenly distributed light. Furthermore, the connection between the tube and the lamp is firm without pulling-off, and the connections between other parts are firm, too.
Description
Technical field
The utility model belongs to light sources technical field, is specifically related to a kind of design of floodlight.
Background technology
Nuclear is that nuclear reactor and other fuel assembly store the lighting apparatus that water observation and operation indispensability are descended in the pond with underwater illuminating device.It must satisfy two primary conditions, i.e. safety and enough brightness fully.At present, the single filament of employing iodine-tungsten lamp light source is arranged, volume ratio is bigger, and both-end seals, and light efficiency is lower, adopts the split pin fastening lampshades, and certain activity is arranged, and has the possibility that comes off, and lacks security, nor attractive in appearance.
Summary of the invention
The purpose of this utility model is to design the high nuclear of good, the luminous utilization rate of a kind of security reliability with the floodlight of anti-irradiation.
The nuclear of the utility model design adopts two tungsten filament halogen tungsten lamps with the floodlight of anti-irradiation, light source, and light source power is 1000-1800W, and light fixture is made up of housing, light source bracket, preceding diffuser and reflector, and its structure as shown in Figure 1-Figure 3.Wherein, light source bracket 10 is used for fixing the two ends of halogen tungsten fluorescent tube 9; Housing 1 is square, the front front opening, and preceding diffuser 4 is fixed in the opening part of housing 1 front front end by rivet, and the lateral cross section of reflector 8 is smooth arc line type, and the edge is fixed on the sidewall of housing 1.
The utility model illumination satisfies the requirement of " nuclear underwater illuminating device ", and 1 meter depths, illumination is greater than 1600Lx.The reflector that uses has been controlled the distribution of light well, makes that the illumination of face to be illuminated is even.Between fluorescent tube and the light fixture, fixed between preceding diffuser and the housing, can not come off.
In addition, light fixture also satisfies following performance requirement:
1, insulaion resistance.In the ambient water of using, between the live part of opposed polarity, between the metal shell of live part and light fixture, and minimum insulation resistance 〉=4M Ω between any other parts.
2, dielectric strength.In air, apply the 1500V alternating voltage between the electrical body of light fixture and the housing, continue 1 minute no punch-through.
3, grounding requirement.Light fixture has good basic insulation and also has reliable ground connection outward.
4, Leakage Current.When operate as normal, the Leakage Current≤1.0mA between each utmost point of power supply and the surface of shell appears.
5, dehydration protection has water to lose protective device, when lamp surfaces under water, can in time cut off the power supply of light source.
6, anti-explosion.Explosion can not take place in normal operation.Even, do not have any sheet of scraping and fall into the environment for use water body in case explosion takes place.
Description of drawings
Fig. 1 is the utility model structure chart (facing).
Fig. 2 is the utility model structure chart (overlooking).
Fig. 3 is the utility model structure chart (side).
Number in the figure: 1 is housing, and 2 is rivet, and 3 is pressing plate, and 4 is preceding diffuser, and 5 is screw, and 6 is packing ring, and 7 is spring washer, and 8 is reflector, and 9 is halogen tungsten lamp, and 10 is light source bracket, and 11 is stuffing-box, and 12 is the aperture on the housing end face.
The specific embodiment
The utility model can have various specification according to different instructions for uses.Further specifically describe this device below by an embodiment.
Light source adopts the 1800W halogen tungsten lamp, single-ended sealing, and housing 1 adopts rectangular build, and front opening, cross section are the hexagon of symmetry, and its length is 420mm, highly is 160mm, and front port place width is 220mm.Light source bracket 10 is arranged in the housing 1, is fixed in the place, two ends of halogen tungsten lamp 10.The power line of fluorescent tube passes the aperture at housing 1 back, and fixing with stuffing-box 11.The length of preceding diffuser 4 and the front opening length of width and housing 1 and width mate, and fix with the front port of housing 1 by rivet 2 and pressing plate 3.Reflector 8 adopts stainless steel material, and cross sections is arc line type (as a hyperbolic-type), is arranged at the inboard of housing 1, and its both sides are fixed in the housing by the clasp of inner walls, the fixing pan head screw 5 that adopts, and upper and lower surface is respectively equipped with packing ring 6 and spring washer 7.Both ends of the surface at housing 1 have some apertures 12, and it is the circulation that both can be convenient to water that this aperture requires, and when making the fluorescent tube explosion again, glass fragment can not pass, and to guarantee safety, the every side of aperture 12 quantity is 10-20, and the aperture is about 2.5mm.
The important technological parameters of this light fixture is as follows: power supply 220V, and 50Hz, power 1800W, Luminaire efficiency are 75%, and total light flux is 225361m, and largest light intensity is 1017cd, and beam angle is 106 °, light fixture satisfies the requirement of " nuclear underwater illuminating device " fully.
