Description
Technical field
The present invention relates to a kind of illumination equipment of elevator, the lighting unit using LED as light source of this illumination equipment is arranged on the top of elevator.
Background technology
As the illumination equipment used in lift car, usually lighting unit is arranged on top, and fluorescent lamp is arranged on lighting unit.In recent years, in order to realize energy-saving, the illumination equipment (such as with reference to patent documentation 1) using the luminous elements such as LED as light source is proposed.
At first technical literature
Patent documentation
Patent documentation 1: Japanese Patent Laid-Open 2011-105433 publication (numbered paragraphs 0014 ~ 0024, Fig. 2)
In the prior art, the illumination equipment being arranged on elevator car roof is configured to have lighting unit, framework and shield, this lighting unit is provided with multiple LED as light source, framework is used for arranging this lighting unit, the material that shield has light transmission by propylene etc. is formed, and is arranged on the peristome of framework removably.Whether shield splits the volume depending on lift car, in the lift car that volume is larger, from the angle keeping intensity, usually shield is divided into multiple shield, and in partitioning portion intercalation joint frame.
When using the luminous elements such as LED in the illumination equipment with above-mentioned existing structure, can shade be produced near joint frame, thus there is the problem of ornamental decline.That is, as shown in Figure 4 and Figure 5, if do not consider the factor of joint frame 7 when being provided as the LED3a of luminous element, then because LED is compared with fluorescent lamp, single led light quantity is little, and the light penetrated from the LED3a adjacent with joint frame 7 is subject to joint frame 7 to be stopped and produces shade S at the diffusingsurface of shield 6.Illumination equipment involved by above-mentioned background technology is studied in the installation method of LED, makes it possible to carry out easily arranging operation and changing operation, but this illumination equipment does not make consideration to the shade produced because of joint frame.
Summary of the invention
The present invention makes in view of practical problems existing in above-mentioned prior art, the object of the present invention is to provide a kind of illumination equipment of elevator, and it can reduce the shade produced by joint frame in use LED is as the illumination equipment of light source.
Solution
To achieve these goals, the invention provides a kind of illumination equipment of elevator, it has: LED-baseplate, and described LED-baseplate is provided with multiple LED; Framework, described framework is arranged on the top of lift car, for arranging described LED-baseplate; The shield of light transmission, the shield of described light transmission is divided into the shield of polylith light transmission, and is arranged on the opening portion of described framework; And joint frame, described joint frame intercalation is at the partitioning portion of described shield, and the feature of the illumination equipment of described elevator is, is arranged on directly over described joint frame by a part of LED in described LED-baseplate along described joint frame.
Invention effect
According to the present invention, at use LED as in the car illumination equipment of light source, the shade produced in the joint frame of the partitioning portion of shield by intercalation can be reduced, LED can be used thus to realize energy-saving, and the ornamental decline in lift car can be prevented.

Detailed description of the invention
Be described referring to the embodiment of accompanying drawing to the illumination equipment of elevator involved in the present invention.
As shown in Figure 1, the top of lift car 1 is provided with illumination equipment 2.
As shown in Figures 2 and 3, illumination equipment 2 has: LED-baseplate 4, and LED-baseplate 4 is provided with multiple LED3; Framework 5, framework 5 is arranged on the top of lift car 1, for arranging LED-baseplate 4; The shield 6 of light transmission, the shield 6 of light transmission is divided into the shield of polylith (such as 4 pieces) light transmission, and is arranged on the opening portion of framework 5; The joint frame 7 of non-light transmittance, joint frame 7 intercalation, at the partitioning portion of described shield 6, has the cross section roughly in H word shape; Carrier member 8, carrier member 8 is arranged on the edge of framework 5, has the cross section roughly in コ word shape; LED-baseplate 4 is fixed on the bolt 9 on framework 5; The cable 10 be connected with LED-baseplate 4; And adaptor union 12, adaptor union 12 is arranged on the end of cable 10, can be connected with the power supply 11 of elevator.Wherein, above-mentioned so-called lighting unit is formed by LED3 and LED-baseplate 4.
A part of LED3A of LED3 is arranged on directly over joint frame 7 along this joint frame 7.
The size of shield 6 is greater than the size of the rectangular aperture formed by joint frame 7 and carrier member 8 slightly.Shield 6 is mounted in joint frame 7 by making its 2 limits, and makes its other 2 limits be mounted on carrier member 8 and be supported.
In the present embodiment, because shield 6 is divided into 4 parts, so joint frame 7 is as shown in Figure 3 in cross shape, the end of the joint frame 7 roughly in H word shape be made up of upper surface portion and bottom surface section is supported by carrier member 8.
In the present embodiment, after being connected with power supply 11 by adaptor union 12, LED-baseplate 4 is energized, each LED3 electrified light emitting thus.By a part of LED3A in LED3 is arranged on directly over joint frame 7 along this joint frame 7, can utilizes and eliminate from the light of the LED3A injection be arranged on directly over joint frame 7 light penetrated because of the LED3 adjacent with joint frame 7 and be radiated at the shade that joint frame 7 produces at the diffusingsurface of shield 6.
According to the present embodiment, be arranged in the illumination equipment 2 in lift car 1 at use LED as light source, the shade because intercalation produces in the joint frame 7 of the partitioning portion of shield 6 can be reduced, therefore, it is possible to use LED3 realize energy-conservation while, prevent the ornamental reduction in lift car 1.Especially, can utilize and the effect that this simple method realizes reducing luminance deviation is designed to the layout of LED3, that is, not needing the special construction being arranged to adopt large-scale shield in order to cancel joint frame, just can reduce the deviation of brightness.
