The limit, left side and the distance between the right edge of echo area, described top can be 70～90mm, the present invention does not do any qualification to this, this size is for the area of controlling sensitive surface or height, and the area of sensitive surface with highly all be to have differently according to situation on the spot, this is a preferred version.
As shown in Figure 7, described reflector further comprises a lower left quarter echo area 60 and a right lower quadrant echo area 70, and the left side edge joint of the right edge of described lower left quarter echo area 60 and described left part echo area closes, and extends to form downwards along the limit, left side of left part echo area; The limit, left side of described right lower quadrant echo area 70 engages with the right edge of described right part echo area, and extends to form downwards along the right edge of right part echo area.Wherein, extend downwards can be meant that oblique below is extended or under extend, the present invention does not do any qualification to this.The present invention is by being provided with a lower left quarter echo area and a right lower quadrant echo area, mainly is in order to consider reflector combined with lampshade, is convenient to insert in the mounting groove.
Described front shroud is white towards the surface of light source one side.The surface of perhaps described front shroud backlight one side also is a white.Wherein, because the reflector efficiency of white is the highest, can improve the reflection efficiency of light fixture, the light of upsetting makes light more evenly soft.
Described front shroud is the insulator material towards the surface of light source one side; The surface of perhaps described front shroud backlight one side is the insulator material; Further, described front shroud is the insulator material.The insulator material can make electric field that the influence of fluorescent tube is reduced, and makes lamp luminescence more abundant, has prolonged the service life of fluorescent tube.
Described front shroud can be composite construction, comprises base material and reflector layer, and described reflector layer is formed by the insulator material as the side towards light source.
What it should be noted that ordinary meaning covers base material by plating mode with reflectorized material last, and it is said by reflective material layer formation composite construction is set on the substrate to form the present invention.
Described reflector layer can be formed on the described base material by hot pressing, stickup or spraying, and the present invention does not do any qualification to this.The composite construction of described front shroud also can be by reflector layer and base material is one-body molded constitutes, promptly when producing, just carry out reflector layer by hot press or mode such as bonding and base material one-body molded, the present invention does not do any qualification to this.
The base material of described front shroud is the insulator material with intensity, can be the insulator material different with reflector layer, so long as have intensity, the insulator material that is not easy deformation can use the present invention, the present invention does not do any qualification to this.
The base material of described front shroud also can be metallic plate.For example: described metallic plate is an aluminium sheet; Perhaps described metallic plate is a steel plate, or the like.The present invention does not do any qualification to this.
Thickness for front shroud among the present invention does not limit, as long as can guarantee the certain intensity of described front shroud.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
