Abstract

The utility model discloses a blackboard lamp which comprises a lampshade and a lamp tube in the lampshade, wherein a reflection plate is arranged at one side of the lampshade toward the lamp tube; and the reflection surface of the reflection plate is a paraboloid. Preferably, a grid plate is arranged at the opened part of the lampshade; the grid plate comprises a plurality of parallel grid bars; and all the grid bars are respectively vertical to the length direction of the lamp tube. According to the blackboard lamp provided by the utility model, the irradiated area can be enlarged and the brightness can be improved; and according to the reflection plate of the blackboard lamp, the concentration performance of a light source, the illumination of the backboard surface and the uniformity of the irradiation can be improved. According to the blackboard lamp, the condition that the opened parts of the conventional lampshades are not provided with grid bars in general is improved, the grid plate is added and all the grid bars of the grid plate are arranged in a same direction, so that the parallel effect of the light irradiation is good.

Description

A kind of blackboard lights
Technical field
The utility model relates to a kind of illuminating lamp of blackboard, the blackboard lights of particularly a kind of optically focused property height and diffusion face width.
Background technology
Blackboard lights generally comprises the fluorescent tube in lampshade and the lampshade, and the light that fluorescent tube sent is launched from the opening of lampshade.
In order to improve illuminating effect, generally can luminous plaque be set at the inwall of lampshade, will reflect back from the incident ray of fluorescent tube.The blackboard lights emergent light shines local blackboard surface, does not reach irradiation fully.The narrow illuminating effect of diffused light shadow surface of blackboard lights is poor.
The utility model content
The utility model provides a kind of blackboard lights, and its optically focused property is high, and the light-emitting window diffusingsurface can overcome the not good problem of blackboard lights illuminating effect than broad.
A kind of blackboard lights comprises the fluorescent tube in lampshade and the lampshade, is provided with reflector at lampshade towards a side of fluorescent tube, and the reflective surface of described reflector is parabolic.
Reflective surface is the optically focused property that paraboloidal reflector can improve light source, makes light generation scattering obtain good illuminating effect.
In order to improve spotlight effect, the light that makes blackboard lights emission is as much as possible near directional light, as preferably; Described fluorescent tube is a strip; The opening of lampshade is provided with Turbogrid plates, and described Turbogrid plates comprise some the grizzly bars that are parallel to each other, and all grizzly bars are all perpendicular to the length direction of fluorescent tube.
The situation of in the utility model the opening of existing lampshade not being established grizzly bar is usually improved, and has increased grizzly bar, and all along same direction layout, the parallel effect of irradiate light is good for all grizzly bars.
For the ease of the installation of grizzly bar, be useful on the fixedly frame of grizzly bar end as preferred outer periphery at grizzly bar.
The spacing of described grizzly bar can preferred 20~60mm, and width can preferred 20~50mm.Suitable spacing and width more help forming parallel emission light.
As preferably, described reflector and lampshade inwall fit, and the cooperation of the two structure can make the profile of blackboard lights compactness more attractive in appearance.
As another kind of embodiment, the inwall of described lampshade is double makees described reflector, and this moment, the inwall of lampshade was provided with reflecting coating, can adopt general reflecting coating, and this can be so that the overall weight of blackboard lights alleviates, and structure is simpler, reduces cost of manufacture.
It is long-pending that the blackboard lights of the utility model can enlarge face to be illuminated, improves brightness; The reflector of blackboard lights can improve the optically focused property of light source, the illumination of blackboard surface and the uniformity of irradiation; The utility model also improves the situation that the opening of existing lampshade is not established grizzly bar usually, has increased Turbogrid plates, and all along same direction layout, the parallel effect of irradiate light is good for all grizzly bars of Turbogrid plates.
Description of drawings
Fig. 1 is the structural representation of a kind of blackboard lights of the utility model;
Fig. 2 is the profile in A-A cross section among Fig. 1.
The specific embodiment
Introduce the specific embodiment of the utility model below.
A kind of blackboard lights as shown in Figure 1 in conjunction with Fig. 2, comprises the fluorescent tube 2 in lampshade 1 and the lampshade 1, is provided with reflector 3 at lampshade 1 towards a side of fluorescent tube 2, and the reflective surface of reflector 3 is parabolic.Reflective surface is 3 optically focused property that can improve light source of paraboloidal reflector, under dust makes the situation of light generation scattering, also can access good illuminating effect.
In order to improve spotlight effect, the light that makes the blackboard lights emission is as much as possible near directional light, in the present embodiment; Fluorescent tube 2 is a strip; The opening of lampshade 1 is provided with Turbogrid plates 4, and Turbogrid plates 4 comprise the grizzly bar of some mutual average row, and all grizzly bars are all perpendicular to the length direction of fluorescent tube 2; In the practical implementation process, the distance between the adjacent grizzly bar is 20~60mm, and the width of grizzly bar can be 20~50mm.The grizzly bar of Turbogrid plates 4 also can select for use screen to replace, and (spacing of screen can be 20~60mm) to screen plate face perpendicular to being parallel to each other between the length direction of fluorescent tube 2 and the screen.Form the grizzly bar or the screen of Turbogrid plates 4 and all arrange, to improve the parallel effect of irradiate light along same direction.Convenient for the grizzly bar or the screen installation that make Turbogrid plates 4, the periphery of grizzly bar or screen can be provided with the frame 5 that is used for fixing grizzly bar or screen end.
In the present embodiment, reflector 3 fits with the inwall of lampshade 1, and the cooperation of the two structure can make the profile of blackboard lights compactness more attractive in appearance.As another kind of embodiment, reflector 3 can be done by the inwall of lampshade 1 is double, and this moment, the inwall of lampshade 1 was provided with reflecting coating; Reflecting coating can adopt general reflecting coating, and this can be so that the overall weight of blackboard lights alleviates, and structure is simpler, reduces cost of manufacture.
