Abstract
The utility model discloses a kind of Down lamp with guide-lighting paper, including trumpet shell, expansion tabula rasa, substrate, LED light group and drive circuit；Substrate and drive circuit are located in trumpet shell, and LED light group drives lighting for LED light group on substrate, by drive circuit；Expand tabula rasa at the light-emitting window of trumpet shell lower end, expand above tabula rasa and post guide-lighting paper；Drive circuit connects outer supply lines, and outer supply lines is provided with primary and secondary plug.The utility model can make light efficiency heighten 20% or so by pasting guide-lighting paper on expansion tabula rasa under identical power；By setting primary and secondary plug on outer supply lines, when changing Down lamp, electric wire directly plug can be completed, and the time of effectively save replacing and installation, improve efficiency.
Description
Technical field
The utility model patent is related to electronic technology field, more particularly to a kind of Down lamp with guide-lighting paper.
Background technology
As the improvement of people's living standards, the requirement to indoor decoration also gradually increases, Down lamp has and can kept
The entirety of building decoration it is unified with it is perfect the features such as and be used widely.Although present Down lamp light is soft, can make room
The problems such as interior trim is more attractive in appearance, but also generally existing light efficiency is low, illuminating effect is bad.
In addition, existing frequently-used Down lamp, when installation, its electrical energy inputs (electric wire) generally wants electrician's rewiring,
Installation replacing is cumbersome, and efficiency is low.
Utility model content
To solve the above problems, the utility model provides a kind of Down lamp with guide-lighting paper.
The utility model realizes above-mentioned purpose by following technical proposal：
A kind of Down lamp with guide-lighting paper, including trumpet shell, expansion tabula rasa, substrate, LED light group and drive circuit；Base
Plate and drive circuit are located in trumpet shell, and LED light group drives lighting for LED light group on substrate, by drive circuit；Expand
Tabula rasa expands above tabula rasa at the light-emitting window of trumpet shell lower end and posts guide-lighting paper.
Further, the both sides outside the trumpet shell are provided with resilient clamping mechanism；The resilient clamping mechanism includes
Torque spring and clamp arm, make clamp arm to clamping at the lower end enlarging of trumpet shell by the elastic torsion of torque spring；
The end of clamp arm is provided with gripping block, and gripping block is provided with anti-skid bulge；, can be easily by Down lamp clip by this set
It is reliable in installed position, fixation.
Further, the drive circuit connects outer supply lines, and outer supply lines is provided with primary and secondary plug；The primary and secondary plug
Including sub- plug and mother socket, " U " type elastic chuck is provided with the outside of the sub- plug, the inwall of the mother socket is provided with
Clamping groove, the U-shaped resilient clip cooperate with the clamping groove, the junction of the sub- plug and the mother socket
It is provided with magnetic ring.
The beneficial effects of the utility model：
1st, by pasting guide-lighting paper on expansion tabula rasa, light efficiency can be made to heighten 20% or so under identical power；
2nd, by setting primary and secondary plug on outer supply lines, when changing Down lamp, electric wire directly plug can be completed, effectively
The time changed and installed is saved, improves efficiency.
Brief description of the drawings
Fig. 1 is that schematic diagram is disassembled in the utility model part；
Fig. 2 is to expand above tabula rasa to paste the cross section structure schematic diagram after guide-lighting paper；
Fig. 3 is the oblique top view of the utility model stereochemical structure.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：A kind of Down lamp with guide-lighting paper, as depicted in figs. 1 and 2, including trumpet shell 1, expansion tabula rasa 2, base
Plate 3, LED light group 4 and drive circuit.Substrate 3 and drive circuit are located in trumpet shell 1, and LED light group 4 is located on substrate 3,
By lighting for drive circuit driving LED light group 4.Expand tabula rasa 2 at the lower end light-emitting window of trumpet shell 1, expand tabula rasa 2 and paste above
There is guide-lighting paper 5.
Enter respectively to common LED Down lamp and in the case where expanding above tabula rasa the Down lamp for posting guide-lighting paper and being all 6W in power
Row spectroscopic analysis system is tested, and is as a result shown：
The light efficiency of common LED Down lamp is 56.96lm/W, and the light efficiency for the Down lamp for posting guide-lighting paper on expansion tabula rasa is
74.24lm/W.That is, the latter's light efficiency improves about 20% with respect to the former.
As shown in figure 3, the both sides outside trumpet shell 1 are provided with resilient clamping mechanism 6.Resilient clamping mechanism 6 includes torsion
Spring 61 and clamp arm 62, make clamp arm 62 at the lower end enlarging of trumpet shell 1 by the elastic torsion of torque spring 61
Clamp.The end of clamp arm 62 is provided with gripping block 63, and gripping block 63 is provided with anti-skid bulge.By this set, can facilitate
Ground is reliable in installed position, fixation by Down lamp clip.
Drive circuit connects outer supply lines, and outer supply lines is provided with primary and secondary plug 7.Primary and secondary plug 7 includes sub- plug and mother
Socket, " U " type elastic chuck is provided with the outside of sub- plug, the inwall of the mother socket is provided with clamping groove, the U-shaped bullet
Property clamp and the clamping groove cooperate, the junction of sub- plug and the mother socket is provided with magnetic ring.By outside
On supply lines set primary and secondary plug, when changing Down lamp, electric wire directly plug can complete, it is effectively save replacing and install when
Between, improve efficiency.
The utility model, which does not elaborate, partly belongs to techniques known, all in spirit of the present utility model and former
Within then, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
