Classroom lamp commonly used at present has two kinds: little grid light fixture and big grid light fixture; The luminous intensity distribution shape of general little grid light fixture all is the cosine luminous intensity distribution, and this light fixture largest light intensity is basically under lamp, and luminous flux all relatively concentrates on the lamp lower part; The light intensity on directive next door is very low; The sort of higher uniformity of illuminance of wanting to reach standard-required has only the light fixture quantity that increases use just passable, otherwise it is separated the bright inner room in classroom to occur, and illumination is situation on the low side evenly; Also has the bigger light fixture of a kind of grid in addition; The luminous intensity distribution shape can be made the batswing tab luminous intensity distribution; This type light fixture largest light intensity is point under lamp not; Change the light fixture largest light intensity just on 45 ° of directions, this light fixture can make the uniformity of illuminance in the bigger zone reach higher level with respect to the cosine light distribution lamp.Big grid light fixture characteristics are: good uniformity, can be issued to the minimum requirements of brightness value and uniformity of illuminance in the relatively low situation of power density, but dazzle is higher; Little grid light fixture characteristics are: dazzle is controlled well, but uniformity is relatively poor, and the minimum requirements desired power density value that reaches brightness value and uniformity of illuminance is higher.

Summary of the invention

The utility model technical issues that need to address are: in order to overcome the problem that exists in above-mentioned, a kind of have light efficiency height, luminous intensity distribution is reasonable and dazzle is low a kind of desk illumination special lamp are provided.

The utility model solves the technical scheme that its technical problem adopted: a kind of desk illumination special lamp; Comprise the lamp body of arcuate structure and be installed in reflection shield and the fluorescent tube in the lamp body cavity successively and be installed in the electric ballast that is used to control fluorescent tube on the lamp body medial surface; Electric ballast is that a kind of employing electronic technology drives electric light source; Make it to produce the electronic equipment of required illumination; Be connected with the suspension rod that is used for fixing on body of wall on the described lamp body outer arcuate face, the arc opening end of described lamp body is provided with the anti-dazzle trellis system.

In order to make luminous intensity distribution reasonable, light output is high, and dazzle is low, and described reflection shield is made up of the laminar curved surface.

For can be in use; Can play and prevent dizzy effect; Described trellis system is made up of with the grid sheet that is arranged on the support the support that is used to be installed on the lamp body openend, and grid sheet has some, is covered with on entire bracket; This kind grid has good uniformity, dazzle is controlled well, and the relatively low situation of power density is issued to the minimum requirements of brightness value and uniformity of illuminance again.

When illumination Design, need select Luminaire efficiency height, high, the rational light fixture of distribution curve flux shape of dazzle credit rating; The design analysis of the science of carrying out, according to different classroom illumination requirement, the light fixture quantity that calculating needs, the light fixture of selecting performance to be fit to carries out lamp installation again and makes the luminous environment in whole classroom reach the requirement of architectural design relevant criterion.
