Abstract
The utility model discloses a special multi-curve asymmetric light-distribution single tube lamp for lighting of blackboard in classroom. The special multi-curve asymmetric light-distribution single tube lamp comprises a lampshade, a reflecting cover and a single tube fluorescent lamp, wherein the reflecting cover is formed by connecting a plurality of paraboloid-shaped surfaces, and the section of the reflecting cover is formed by connecting plurality of parabolas from end to end; and the lengths of the parabolas are not equal to one another, and the parabolas are gradually prolonged from the single tube fluorescent lamp to outside. Through the technical scheme of the utility model, the special lamp for lighting of the blackboard in the classroom utilizes a multi-curve light distribution manner so that the lighting ranges of the blackboard in the classroom are centralized on the blackboard, the illuminance of the blackboard can be up to the standard, the glare rating is up to the standard, and a comfortable learning environment is created. The utilization of limited lights is maximized and a purpose of energy saving emission reduction is realized; simultaneously, a projection angle of a projector is considered when the mounting position of the special lighting lamp of the blackboard is designed so that the special lighting lamp of the blackboard does not disturb the projection of the projector.
Description
Technical field
The utility model relates to a kind of classroom blackboard illumination special lamp, is specially a kind of many curves luminous intensity distribution single tube classroom blackboard illumination special lamp; Belong to field of illuminating lamps.
Background technology
The situation that current student eyesight descends is very outstanding, though reason is many-sided, the most directly reason be the classroom look environment is bad to be caused.Therefore, how to carry out classroom blackboard illumination Design, accomplish both energy-conservationly, each item index is up to state standards again, be to set up a comfortable basis of looking environment, and be the responsibility that each illumination Design worker should use up.At present domestic common classroom blackboard illumination generally is arranged as 2 groups of light fixtures, and illuminating effect exists the illumination and the uniformity all to reach not national standard, and its consequence makes student's visual fatigue, eyesight descend.Issued new standard GB7793-2010 " middle and primary schools' classroom lighting and illumination sanitary standard " inferior to present situation country.Use the asymmetric luminous intensity distribution single tube of many curves classroom blackboard lighting, can make the illumination of blackboard reach blackboard illumination each item index and requirement in the GB (GB7793-2010).
The utility model content
The goal of the invention of the utility model is for blackboard illumination special lamp in the asymmetric luminous intensity distribution single tube of a kind of many curves classroom is provided; To solve the above-mentioned problems of prior art.
The purpose of the utility model can realize through following technical scheme.
The asymmetric luminous intensity distribution single tube of a kind of many curves classroom blackboard illumination special lamp; Comprise lampshade, reflection shield and single tube fluorescent lamp; Described reflection shield is to constitute some parabolic linkings, and its cross section is a plurality of sections parabola tandem array shape; Described parabola is uneven in length, and is increased gradually outward by single tube fluorescent lamp.
Described parabola is eight sections tandem arrays.
The exiting surface level of described reflection shield, exiting surface level height are at 260-280mm above the blackboard upper edge, and blackboard light fixture center is from blackboard surface 920-950mm, and this installation site does not influence the projection of projecting apparatus.Simultaneously control dazzle well, built a comfortable academic environment.
The classroom blackboard illumination special lamp that designs through the utility model technical scheme; Owing to adopted many curves light-configuration mode, make classroom blackboard illumination zone concentrate on the blackboard zone, blackboard illumination all can be up to standard; The value of dazzle simultaneously is up to standard, builds a comfortable academic environment.With the utilization maximization of limited light, reach the purpose of energy-saving and emission-reduction.The position of this blackboard illumination lamp installation has been considered the crevice projection angle of projecting apparatus when design simultaneously, so this blackboard illumination light fixture can not disturb the projection of projecting apparatus.
Description of drawings
Fig. 1 is the mounting structure sketch map of the utility model; Dotted portion among the figure is a drop shadow spread.
Fig. 2 is the irradiation sketch map of the utility model light; Dotted portion among the figure is an illumination range.
Among the figure: 1, reflection shield.
The specific embodiment
Further set forth the structural representation of the utility model below in conjunction with accompanying drawing and specific embodiment;
As shown in Figure 1, the asymmetric luminous intensity distribution single tube of a kind of many curves classroom blackboard illumination special lamp; Comprise lampshade, reflection shield 1 and single tube fluorescent lamp; Described reflection shield 1 is that some parabolic 2 linkings constitute, and its cross section is a plurality of sections parabola tandem array shape.
The installation of asymmetric luminous intensity distribution single tube classroom blackboard illumination special lamp: level is installed (exiting surface level); The exiting surface level height is from above the blackboard upper edge about 270mm; Blackboard light fixture center is from about blackboard surface 940mm, and this installation site does not influence the projection of projecting apparatus.Simultaneously control dazzle well, built a comfortable academic environment.Utilization maximization, rationalization with limited light reach energy-conservation, comfortable purpose.
By standard classroom is example: the standard classroom area is a 7.5*9 rice, blackboard area 1.2*4 rice, and what existing market was used is 2 covers, 36～58W blackboard lights.
Use the single tube classroom blackboard special lamp 2 cover 1*58W of the utility model, blackboard illumination is greater than 500Lx, and the uniformity (minimum/average) is greater than 0.8.
This shows that the single tube classroom blackboard special lamp that designs through the utility model can satisfy the advantage that illumination can satisfy uniformity technical requirement characteristic again.
