Embodiment
Reference picture 1, a kind of transparent anti-dazzle grating, including a grid arranged by multiple grille strips 11 in right-angled intersection
Formula flase floor 10, grille strip 11 vertically includes close to sources section 111 and remote source stage 112, by adjacent close to sources section 111
The through hole formation light source rest area surrounded, the longitudinal section area of remote source stage 112 is more than the longitudinal section face of close to sources section 111
Product, specifically, the longitudinal section area of remote source stage 112 is 1.5 times to 2 times of the longitudinal section area of close to sources section 111, distance light source
112 vertical side of section and the lateral separation of its longitudinal axial centerline towards close to close to sources 111 directions of section in tapered to set, dipped beam
Source 111 vertical side of section and the lateral separation of its longitudinal axial centerline towards away from the remote direction of source stage 112 in tapered to set, lattice
The section of grizzly bar 10 is wedge shaped, the angle between 20 ° -60 ° of two hypotenuses formation, 111 parts away from remote source stage 112 of close to sources section
In tip-angled shape, lateral out side of the remote source stage 112 away from close to sources section 111 is horizontal.
Specifically, grille strip 11 is made into integration by clear polycarbonate or polymethyl methacrylate or glass, in theory,
As long as all transparent materials that refractive index is more than air can be used as grid raw material, it is contemplated that Shooting Technique needs and material is resistance to
By makrolon (PC) is proper selection, and PC transmitances are higher, therefore light utilization efficiency is higher, supporting transparent grid use
Lamp panel, as long as original lamp panel can install traditional grid, alternatively use, including fluorescent tube, LED lamp tube, area source
Etc., to ensure good antiglare effect, the light source position of original lamp panel is deep enough, to ensure having larger shielding angle, keeps away
Exempt from light source to be looked at straight, shape, the size of transparent grid can be specific outer to meet according to the Design of Luminaires specifically used cooperatively
See and performance requirement.
Index path of the light source emergent ray after transparent grille strip 11 is reflected and reflected is as shown in figure 3, light fixture adds lattice
Distribution curve flux figure before and after screen 10 as shown in figure 4, wherein the distribution curve flux of fine line for plus flase floor 10 before distribution curve flux,
The distribution curve flux of heavy line is adds the distribution curve flux after flase floor 10, and the light of light source outgoing is in the refraction by the grille strip 11
After reflection, originally deflected with the larger light of exiting surface vertical direction angle towards the less direction of angle, so that former
Originally the light for appearing in human eye glare area is deflected to light fixture operating illumination region, and one side dazzle is under control, the opposing party
Face also improves light utilization efficiency.
In summary, the transparent anti-dazzle grating by set one by multiple cross arrangements of grille strip 11 grid type lattice
Screen 10, is vertically set to close to sources section 111 and remote source stage 112 by grille strip 11, light source (not shown) is placed
In the through hole 12 that adjacent close to sources section 111 is surrounded, remote source stage 112 is set to vertical side and its longitudinal central
The lateral separation of line with towards close to close to sources section 111 direction tapered configurations, while nearly source stage 111 be set to vertical side with
The lateral separation of its longitudinal axial centerline is with towards away from the remote direction tapered configuration of source stage 112 so that the light of light source outgoing is in warp
After the refraction and reflection of crossing the grille strip 11, originally the light larger with exiting surface vertical direction angle was towards the less side of angle
To deflection, so that the light for appearing in human eye glare area originally is deflected to light fixture operating illumination region, one side dazzle
It is under control, on the other hand also improves light utilization efficiency, therefore the transparent anti-dazzle grating has suppression dazzle and effectively improved
The advantage of light utilization efficiency.
Embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading the utility model protection domain
For.
It is to preferably embody in the utility model in addition, the example for the specific material that the utility model is provided
The technique effect of product, material therefor not the utility model scope of the claimed in itself.
