The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
The embodiment of the invention is designed to round rib structure with the inner surface of light fixture transparent member, and carries out blasting treatment, and the light that light source sends is through the transparent member transmission, the transmissivity height, and illumination evenly distributes, and free from glare and ghost image.
The inner surface of the light fixture transparent member that the embodiment of the invention provides is provided with multi-turn concentric circles lug, nib, and the faceted pebble of described lug, nib is provided with the sand grains layer of anti-dazzle effect.
The LED light fixture that the embodiment of the invention provides comprises: housing, be located at a plurality of LED in the described housing and be used for installing the substrate of described a plurality of LED, the middle part of described housing is provided with transparent member, the inner surface of described transparent member is provided with multi-turn concentric circles lug, nib, and the faceted pebble of described lug, nib is provided with the sand grains layer of anti-dazzle effect.
Below be elaborated as the specific implementation of light source to the embodiment of the invention with LED.
Shown in Fig. 1～5, the LED light fixture that the embodiment of the invention provides comprises: housing 11, the substrate of being located at a plurality of LED12 in the housing 11 and being used for installing a plurality of LED12.Housing 11 is rounded, and the middle part of housing 11 is provided with transparent member 14.The inner surface of transparent member 14 is provided with multi-turn concentric circles lug, nib 141, and outer surface is smooth flat.The faceted pebble of lug, nib 141 is provided with the sand grains layer of anti-dazzle effect, and the light that LED12 sends forms area source in faceted pebble generation diffuse reflection through transparent member 14 outgoing, can not cause dazzle and ghost image.Because not adding emulsifying agent in the transparent member 14, its transmissivity can reach more than 90%, and the light efficiency of LED light fixture is also high.
In the embodiment of the invention, light fixture transparent member 14 is done blasting treatment to the faceted pebble of lug, nib 141 after adopting the injection mo(u)lding of PC material, forms a sand grains layer.Blasting craft requires as follows: adopt 60
#Sand grains, sandblast air pressure are 0.8～1MPa, and the sandblast time is 2～3 minutes, and nozzle is apart from about the transparent member 10cm, to the even sandblast of the faceted pebble of lug, nib 141.The outer surface of transparent member 14 need not blasting treatment.
As shown in Figure 6, the preferred luminous angle of the embodiment of the invention more than or equal to 90 ° LED12 as light source.The outgoing beam angular dependence (-dance) of the corner angle θ of lug, nib 141 and the beam angle of single LEDs and light fixture.Suppose that it is that the beam angle of LED light fixture is compared with the beam angle of LED that transparent member 14 makes the beam angle of LED12 enlarge the α degree, enlarged the α degree, then the corner angle θ of lug, nib 141 is:
θ＝2Arctan(|1/nsinα-1/tanα|)......(1)
