Description
Technical field
The utility model relates to a kind of LED total-reflection type lighting, refers to that especially light emitting diode directly is installed in the temperature-uniforming plate top quickens the time of heat exchange, and can change illumination range according to the shape of reflecting part.
Background technology
The power consumption height of conventional lamp, service life is short, and easily produce electromagnetic pollution and mercury pollution etc., also serious day by day for problem that environmental protection produced, be not inconsistent the requirement of energy savings, so promptly there is relevant dealer to utilize a plurality of light emitting diodes to make light fixture at present, to replace conventional lamp, the principle of luminosity of light emitting diode makes carrier injection exhaustion region and at exhaustion region the compound photon of emitting takes place for utilization adds reverse bias, passing to minimum current/voltage just makes it luminous, so wasted power is less and the life-span is long, compared with general conventional bulb, can save many electric energy, its shortcoming is exactly, the not good and light source that send of optically focused is a straight line light, so the light source of local block only can be provided, if the user looks at this light source straight and easily the vision with the user is produced dazzle, in addition, the light emitting diode greatest problem be input power have an appointment the energy of 80-90% can loss, these losses most likely produce used heat, therefore, the fluorescent tube that this type of light emitting diode is made be because of can't effectively dispelling the heat to the used heat that light emitting diode produced, and then the luminous efficiency of light emitting diode and life-span are reduced.
Therefore, how to solve above-mentioned known problem and shortcoming, be the problem of being engaged in research and development that this relevant dealer desires most ardently.
Summary of the invention
Main purpose of the present utility model is, light emitting diode directly is installed in the temperature-uniforming plate top quickens the time of heat exchange, and can change illumination range according to the shape of reflecting part and avoid the user to make eyes produce the phenomenon of dazzle because of the light source of direct-view light emitting diode.
For reaching above-mentioned purpose, the utility model is provided with pedestal, light supply apparatus, and pedestal is concaved with accommodation space, the accommodation space bottom surface is formed with the reflecting part of reflection source, and this light supply apparatus is provided with temperature-uniforming plate, and the temperature-uniforming plate both side surface is respectively arranged with light emitting diode and radiating fin, these temperature-uniforming plate both sides are positioned at the inboard and the outside of pedestal, and light emitting diode is right against reflecting part, and radiating fin is positioned at the pedestal outside, and is formed with spacing between light emitting diode and the reflecting part.
Further, light emitting diode can be a plurality of.
Further, temperature-uniforming plate can be the thermal conductance tubular type.
Further, pedestal is provided with diffuser, and diffuser is positioned at the accommodation space surface, and is right against reflecting part.
After the utility model made the thermal source of light emitting diode directly carry out heat exchange with temperature-uniforming plate by temperature-uniforming plate, the thermal source that makes temperature-uniforming plate contacted with air thermal source is shed by being positioned at radiating fin outside the pedestal, to reach the effect of quick heat radiating.
In addition, because the utility model makes the light source reflection of light emitting diode by reflecting part, therefore if change the shape of reflecting part, the light source that light emitting diode is projected changes reflection position, and then change light source range of exposures, and because the light source of light emitting diode is transmitted through the external world with the light source reflection by diffuser by reflecting part, so the user can not cause dazzle to influence safety to eyes because of looking at the light source that light emitting diode sends straight.

The specific embodiment
See also Fig. 1, Fig. 2 and shown in Figure 4, find out that by knowing among the figure this lighting is provided with pedestal 1, light supply apparatus 2, wherein:
When the light that light emitting diode 22 is sent when luminous can be towards reflecting part 12 projections, reflection by reflecting part 12 is concentrated light and is throwed towards accommodation space 11 front ends, so the utility model can be according to the shape of reflecting part 12, and the light source that light emitting diode 22 is throwed changes range of exposures, and process diffuser 13 is transmitted through the external world, and light can not spread everywhere, also therefore make the light visibility more extend.
See also shown in Figure 3, find out by knowing among the figure, temperature-uniforming plate 21 can also various different directions and the mode of angle be arranged on a side of temperature-uniforming plate 21, and make light emitting diode 22 be right against the reflecting part 12 of accommodation space 11 reflection sources that the bottom surface forms, by reflecting part 12 light source that light emitting diode 22 sends is reflected, make light towards the projection of accommodation space 11 front ends, concentrate, and then improve brightness so that the light of reflection is better.
See also Fig. 4 and shown in Figure 5, find out by knowing among the figure, the utility model directly adds light emitting diode 22 and is located at temperature-uniforming plate 21 tops, and these temperature-uniforming plate 21 inside are equiped with fluid, light emitting diode 22 is directly contacted with temperature-uniforming plate 21, by temperature-uniforming plate 21 thermal source of light emitting diode 22 and the fluid of temperature-uniforming plate 21 inside are carried out heat exchange, again thermal source is conducted to the radiating fin 23 that is positioned at pedestal 1 outside by temperature-uniforming plate 21, make thermal source outside directly contact that shed carry out heat exchange with air.
See also Figure 6 and Figure 7, but find out can the be monolateral fixing also double-side fastening of light supply apparatus 2 of the present utility model on pedestal 1, so make it when use, can not be subjected to the restriction of light fixture external form by knowing among the figure.
In sum, after the thermal source that the utility model makes light emitting diode 22 by temperature-uniforming plate 21 directly and temperature-uniforming plate 21 carries out heat exchange, the radiating fin 23 of the thermal source that makes temperature-uniforming plate 21 by being positioned at pedestal 1 outside contacts with air thermal source shed, to reach the effect of quick heat radiating.
In addition, because the utility model makes the light source reflection of light emitting diode 22 by reflecting part 12, therefore if change the shape of reflecting part 12, the light source that light emitting diode 22 is projected changes reflection position, and then change light source range of exposures, and because the light source of light emitting diode 22 is transmitted through the external world with the light source reflection by diffuser 13 by reflecting part 12, so the user can not cause dazzle to influence safety to eyes because of looking at the light source that light emitting diode 22 sent straight.
