Description

The light guide structure of light fixture

Technical field

The utility model provides a kind of light guide structure of light fixture, and the light guide structure of You Zhike expansion lamp lighting scope, illumination can be the range expansion of lamp lighting long rectangular-shaped projection effect, can increase the brightness range of lamp lighting.

Background technology

Since electric light is invented, be used for illumination at night, make that night life can be as daytime smoothly, and through fluorescent lamp, desk lamp, desk lamp, wall lamp etc., in order to do outside the indoor illumination, also can utilize street lamp, the art street lamp uses for outdoor illumination, perhaps guide as the caution of roadblock with warning lamp, various indoor or outdoor night illuminations, right present various lightings, when luminous lighting, its light all be rounded shape to external diffusion, and the light at middle position is brighter, more promptly darker toward outer rim light, therefore the scope of illumination is also dwindled relatively, the brightness of illumination deficiency of influence periphery, so several lighting must be set more, brightness that just can additional illumination, but also cause cost to improve because increased lighting quantity being set, also increase relatively of Zhao Ming power consumption simultaneously, also cause the expense of electricity consumption significantly to promote, quite be not inconsistent economic benefit, especially in the moment that present global energy economy seriously is critical, a large amount of uses of the energy will speed up the quick generation of energy crisis especially, though the light fixture of many illuminations changes with Electricity-saving lamp bulb or light emitting diode (LED) as light emitting source, the energy of being saved is still limited; And be used as the light fixture of illumination at night, main out of doors is illumination with the street lamp, indoor then with fluorescent lamp or art lamp appearance light fixture as illumination, and when practical application is implemented, still have many disappearances and puzzlement, as:

(1) because of the illumination zone of street lamp, be confined to light that light emitting source throws circle footpath in, for considering the effect of illumination,, cause the increase of electric power and electricity cost so distance is set also must shortens of street lamp promptly can increase the quantity that is provided with of street lamp.

(2) light fixture of room lighting not good from light fixture peripheral illuminating effect far away slightly, also must be set up lighting in addition with additional illumination brightness, perhaps increase light emitting source and strengthen brightness of illumination, the electricity charge also with increase.

(3) present indoor or outdoor employed lighting, the illumination zone of light all is the irradiation area of rounded shape, and brightness irregularities, causes illuminating effect undesirable, also has a greatly reduced quality in the function of night illumination.

Therefore, how to solve the problem that present lighting is limited because of illumination zone, brightness of illumination is not good, and must increase the quantity of lighting tool setting, the disappearance that causes energy expenditure to increase, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

So, the inventor is because above-mentioned problem and disappearance, collect related data, via assessing in many ways and considering, and to engage in the many years of experience of the industry accumulation, via constantly studying and revise, but the beginning is designed this kind spread illumination scope, the patent of founding of light guide structure of extending the light fixture of illumination light is born.

Main purpose of the present utility model is that this light guide structure has accommodation space in base interior, and the accommodation space periphery is provided with photic zone can be with the outside transmission of light, and it is inner for light emitting module is set, pass photic zone and outwards throw to utilize light emitting source to send light, then between light emitting source, be provided with at least one or but more than one refracting layer directing light outwards throws, in addition in two relative sides of refracting layer, for being respectively equipped with the reflecting layer, can be by the light reflection of reflecting layer with light emitting source, and light is outwards throwed light towards refracting layer is equidirectional, the illumination zone that reaches light fixture is the effect that long rectangular-shaped expansion is throwed, and increases the brightness range of lamp lighting.

Secondary objective of the present utility model is this light emitting module set refracting layer between light emitting source, and section becomes cone-shaped anaclasis body, and the interior angle of the section pointed cone of refracting layer between 10 degree between 45 degree, the light that can effectively guide light emitting source reflects to the outside.

A purpose more of the present utility model is this light emitting module in the set reflecting layer of refracting layer dual side-edge, and for being the arrow shaped setting of relative formula, and the angle of two relative its expansion of placed arrow type reflecting layer can be identical or different angle; If the sagittate reflecting layer of two relative formulas is different angle, and the angle in a reflecting layer between 100 degree between 140 degree, the angle in another reflecting layer is between 40 degree are spent to 80; And the sagittate reflecting layer of two relative formulas is as being identical angle, and then the angle in two reflecting layer can be between 100 degree between 140 degree, and perhaps, the angle in reflecting layer can reach good light reflex between 40 degree between 80 degree.

For achieving the above object, the light guide structure of a kind of light fixture of the present utility model can be expanded the lamp lighting scope, comprises pedestal and light emitting module, and this base interior has accommodation space, and the accommodation space periphery is provided with the photic zone of transmit light; This light emitting module is to be arranged in the accommodation space of pedestal, have and to send light and with the outside light emitting source of projection of the photic zone of light penetration accommodation space, but and be provided with outwards at least one refracting layer of projection of directing light between light emitting source, and two relative sides of at least one refracting layer can be with the reflecting layer of reflection ray towards the equidirectional throw light of refracting layer for being respectively equipped with.

By technique scheme, the useful technique effect that the utility model reaches is:

(1) pedestal 1 of light fixture set light emitting module 2 in accommodation space 10, utilize refracting layer 23, reflecting layer 24, after the refraction of the light of light emitting source 22, reflection, project photic zone 121 outsides towards dual side-edge, reach the effect of spread illumination scope, can prolong light fixture adjacent spacing is set,, consume, reduce electricity charge expenditure and reduce electric power to reduce the usage quantity of light fixture.

(2) light fixture is used as the room lighting use, can utilize light emitting module 2 to produce long rectangular-shaped illumination zone, zone, and have good brightness of illumination, and can reduce the quantity that indoor lamp is provided with, and also can reduce the consumption of electric power, the expenditure of the minimizing electricity charge.

(3) scope that light fixture can spread illumination present long rectangular-shaped field of illumination, and brightness of illumination is respond well, no matter be used in indoorly or outdoor, can reach the bright illumination effect, strengthens the effect of night illumination.
