Specific implementation below in conjunction with specific embodiment to the antiglare equipment of a kind of searchlight of the present invention is described in detail:
embodiment mono-:
Fig. 2 shows the main TV structure schematic diagram of the antiglare equipment that first embodiment of the invention provides, Fig. 3,4 shows solid, the main TV structure schematic diagram of the searchlight lamp cylinder that this antiglare equipment is installed, the master that Fig. 5,6,7 shows respectively the searchlight that this antiglare equipment is installed looks, side-looking, perspective view, Fig. 8-11 show the setting principle schematic diagram one, two, three, four of the antiglare equipment that first embodiment of the invention provides, for convenience of explanation, only show the part relevant to the present embodiment.
With reference to accompanying drawing 2,3,4, the embodiment of the present invention provides a kind of antiglare equipment of searchlight, and mainly by a plurality of (at least two), highly identical cylinder 201 arranges and forms this device with one heart, and the inwall of each cylinder 201 has diffuse reflector.The anti-dazzle function of this antiglare equipment is mainly determined by the length of concentric drums, the parametric synthesis such as diameter of each cylinder.As shown in Figure 5, can spaced set between each cylinder 201.
In the present embodiment, between the adjacent cylinder 201 of this antiglare equipment, can adopt bonding jumper 202 to be fixedly connected with, also can adopt other fixed forms.This antiglare equipment is installed on the light-emitting window place of the lamp cylinder 203 of searchlight, the optical axis coincidence of its central shaft and searchlight light source (as Fig. 5,6).And can make the edge of this antiglare equipment and the justified margin of lamp cylinder, make the whole better appearance (as Fig. 7) of searchlight.
In the present embodiment, for the ease of installing, can make the bonding jumper of stationary cylinder draw from the center of cylinder, and extend to outside the outermost layer cylinder along the radius of cylinder, then make the end of this bonding jumper be connected with the lamp cylinder of searchlight, and then realize the fixing of antiglare equipment.
Can not weaken in a large number again the output intensity of searchlight in order to make this antiglare equipment can reach preferably antiglare effect, the present embodiment has carried out suitable setting to its structure.With reference to accompanying drawing 4,6, the ascending D that is made as respectively of diameter of the cylinder of antiglare equipment will be formed

3... D
n(n is positive integer, n>=2), the centre of luminescence 204 of supposing the searchlight light source is S to the vertical range of antiglare equipment outer ledge, and the height of supposing concentric drums is L, the light-emitting window diameter of supposing the lamp cylinder of searchlight is D, and the anti-dazzle angle of the searchlight of hypothesis product requirement is θ.With further reference to accompanying drawing 8, work as D
1during/2S=tan θ, diameter is D
1cylinder just can block the light that the angle of emergence is greater than θ, therefore block too much light and output intensity produced to larger impact for fear of antiglare equipment, the present embodiment carries out following restriction to above-mentioned parameter:
D
1/2S≥tanθ-----------------------------------------(1)
In embodiments of the present invention, the anti-dazzle angle θ of searchlight is not well-determined, and concrete angle is determined according to actual requirement.Usually the anti-dazzle angle of searchlight is 45 °, and when anti-dazzle requirement is stricter, this anti-dazzle angle is less, as 15 °.
With further reference to accompanying drawing 9, if will make antiglare equipment just the light of wide-angle outgoing be carried out to diffuse reflection and light leak not, above-mentioned parameter also needs to meet following relational expression:
(D

n-----------------------------------------(2)
Be understandable that, under the prerequisite that meets above-mentioned relation formula (1), work as D
1when/2S is excessive with respect to tan θ, has part light and penetrate with the angle that exceeds anti-dazzle angle, its antiglare effect is good not, so D
1/ 2S is unsuitable excessive.Equally, under the prerequisite that meets above-mentioned relation formula (2), as L with respect to (D
n-D
n-1) S/D
nwhen excessive, antiglare equipment has partial-length and is not utilized, and causes waste of material, has also increased the weight of the weight of antiglare equipment simultaneously.So, when the relevant parameter of antiglare equipment meets following the relation, its antiglare effect the best, and stock utilization is the highest:

n。
Continuation is with reference to accompanying drawing 11, with the searchlight of traditional lengthening lamp cylinder, compare, when reaching same antiglare effect, the antiglare equipment that adopts the present embodiment to provide can significantly shorten the length of lamp cylinder, the shortening amount of supposing lamp tube length degree is h, 11 can draw with reference to the accompanying drawings:
(D-D
1)/2h＝D/2(S+h)，
So, h=(D/D
1-1) S.
Adopt antiglare equipment that the present embodiment provides can make the contraction in length (D/D of lamp cylinder
1-1) S.
The antiglare equipment that the embodiment of the present invention provides is comprised of a plurality of contour concentric drums, and the present embodiment has carried out suitable restriction to the relevant parameter of concentric drums, make this antiglare equipment can effectively block the emergent light of wide-angle, and these emergent lights are carried out to diffuse reflection to disperse light intensity (as Figure 12), the dazzle impact of having avoided the high light of wide-angle outgoing to cause near people searchlight, and be convenient to processing.
Above-mentioned antiglare equipment is installed at light-emitting window place at the lamp cylinder of searchlight, can effectively shorten the lamp cylinder for anti-dazzle length, reduces the weight of lamp cylinder, reduces the volume of searchlight and makes searchlight more attractive in appearance.
embodiment bis-:
In embodiments of the present invention, the cylinder quantity that forms antiglare equipment can be 2～8, when quantity is very few, it is long that the length requirement of its cylinder is done, be unfavorable for shortening lamp tube length degree, when quantity is too much, can cause the output intensity decrease of searchlight, therefore amid all these factors consider, the quantity of lamp cylinder can be further defined to 4～6.
embodiment tri-:
