Abstract

The utility model relates to a classroom lamps and lanterns that warn are revealed to ultraviolet, the lamp shade of this lamps and lanterns is close to border position department and has luminousness more than or equal to 95% high light transmission area, and the sign of warning covers at this high light transmission area region surface, and should the sign of warning can light under ultraviolet excitation. The utility model discloses set up the sign of warning in the high printing opacity region of lamp shade, when lamps and lanterns produced the ultraviolet ray and reveal, the sign of warning can light under the ultraviolet ray excitation, sends the visual monochromatic light that is different from the white light colour of people's eye, and the suggestion user in time maintains or changes lamps and lanterns, and the degree of distinguishing of warning is high, and is with low costs, applicable in places such as school, hospital, children's room that require higher to healthy luminous environment.

Description

Classroom lamp for warning ultraviolet leakage

The technical field is as follows:

the utility model belongs to the technical field of the illumination, a LED lamps and lanterns are used in the classroom is related to, indicate the classroom lamps and lanterns that warn are revealed to ultraviolet especially.

Background art:

the lighting products on the market are full of types of linens and have various spectral compositions. The traditional fluorescent lamp utilizes mercury vapor with low air pressure to release ultraviolet rays after being electrified to excite fluorescent powder to emit light, and the risk of ultraviolet leakage exists along with the prolonging of the service time of the lamp. Meanwhile, some LED lamp light sources adopt ultraviolet chips as excitation sources to generate white light at present, and the LED lamp light sources are particularly widely applied in the field of healthy lighting LED lamps. If the lamp is used in an ultraviolet environment for a long time, the lamp can cause a plurality of potential damages to human eyes and skin and even cause cancer. Meanwhile, most schools lack periodic detection on lamp performance and light quality in the use process of the lamp, and are difficult to find and replace dangerous lamps with ultraviolet leakage in time, so that hidden dangers are caused to the health and safety of teachers and students.

The invention content is as follows:

the to-be-solved technical problem of the utility model is to provide a classroom lamps and lanterns that warn are revealed to ultraviolet, this lamps and lanterns easily people's eye direct recognition ultraviolet ray leaks the condition to remind the user in time to change lamps and lanterns, cause harm to the people health in order to avoid ultraviolet to leak.

In order to solve the technical problem, the utility model discloses a classroom lamps and lanterns that warn are revealed to ultraviolet, the lamp shade of this lamps and lanterns of its characterized in that is close to border position department and has luminousness more than or equal to 95% high light transmission area, and the sign of warning covers at this high light transmission area surface, and should the sign of warning can light under the ultraviolet excitation.

The high-light-transmittance area is made of optical glass or optical plastic.

The warning mark is an ultraviolet fluorescent ink icon printed on the outer surface of the high-light-transmittance area.

The warning mark is an ultraviolet fluorescent powder icon printed on the outer surface of the high-light-transmission area.

The warning mark covers on the transparent label paper, and the transparent label paper is stuck on the outer surface of the high-light-transmission area.

The high light transmission area is a light transmission hole.

The warning mark covers on the transparent label paper, and the transparent label paper is pasted on the lamp shade and covers the light hole.

The warning mark is an ultraviolet fluorescent ink icon printed on the outer surface of the transparent label paper.

The warning mark is an ultraviolet fluorescent powder icon printed on the outer surface of the transparent label paper.

The utility model discloses set up warning sign in the high printing opacity region of lamp shade, when lamps and lanterns produced the ultraviolet ray and reveal, warning sign can light under the ultraviolet ray excitation of the following wave band of 400nm, sends the monochromatic light that people's eye is visible to be different from the white light colour, and the suggestion user in time maintains or changes lamps and lanterns. The utility model discloses the degree of distinguishing of warning is high, and is with low costs, applicable in places such as school, hospital, children's room that require higher to healthy luminous environment.

Detailed Description

A600X 600mm flat lamp will be described below as an example.

Example 1

As shown in fig. 1 and 2, a lamp cover 1 of the lamp has a high light transmission area 2 with a regular triangle shape having a light transmission rate of 95% or more near an edge, the high light transmission area 2 is made of optical glass or optical plastic (such as PMMA, PC, etc.), and the warning mark 3 is an ultraviolet fluorescent ink icon or an ultraviolet fluorescent powder icon printed on an outer surface of the high light transmission area 2.

The side length of the high light transmission region 2 of the regular triangle is about 30 mm.

Example 2

As shown in fig. 3 and 4, a circular high-light-transmission area 2 with a light transmittance of 95% or more is arranged at a position, close to the edge, of a lampshade 1 of the lamp, and the high-light-transmission area 2 is made of optical glass or optical plastic; the warning mark 3 is an ultraviolet fluorescent ink icon or an ultraviolet fluorescent powder icon printed on the outer surface of the transparent label paper 4, and the transparent label paper 4 is adhered to the outer surface of the high light-transmitting area 2.

The circular high transmission area 2 is about 30mm in diameter.

Example 3

As shown in fig. 5 and 6, the lamp shade 1 of the lamp has a light-transmitting hole 5 as a high light-transmitting area near the edge; the warning mark 3 is an ultraviolet fluorescent ink icon or an ultraviolet fluorescent powder icon printed on the outer surface of the transparent label paper 4, and the transparent label paper 4 is stuck on the lampshade 1 and covers the light hole 5.

The light hole 5 can be circular, and the diameter of the transparent label paper 4 is slightly larger than that of the light hole 5. The diameter of the light hole 5 can be 25mm, and the diameter of the transparent label paper 4 can be 38 mm; the warning label 3 may be printed in an area of 25mm diameter in the center of the transparent label paper 4.

The warning sign 3 can change colour when the wave band ultraviolet irradiation below 400nm, in case lamps and lanterns light source part became invalid, when there was wave band ultraviolet leakage below 400nm, this warning sign will highlight (show that the colour can be red, yellow, blue, green etc. easily people's eye discernment bright colour), when this condition of user discovery appeared, alright in time change or maintain this lamps and lanterns, the injury that the ultraviolet ray pair of in time effectual avoiding revealing led to the fact the human body.

The lamp not only refers to a plane lamp, but also refers to a strip lamp, a blackboard lamp and other forms of LED lamps.

The warning mark is not limited to the patterns shown in fig. 2, 4 and 6, and other patterns with reminding functions can also be adopted.
