Abstract
The utility model relates to a heat dissipation type lampshade used for a candle lamp, which is mainly used for decorating an illumination place and belongs to the field of semiconductor illumination. The lampshade takes U-shaped metal frameworks as support frameworks and transparent components as light transmitting bodies; and the plurality of U-shaped metal frameworks are supported mutually to form a semioval cone, the transparent components are arranged among the U-shaped metal frameworks, and the outer surfaces of the U-shaped metal frameworks are contacted with the external air. Compared with glass or plastic lampshades used for the present candle lamp, the heat dissipation type lampshade used for the candle lamp is better in auxiliary heat dissipation, and effectively lowers the temperature of a heat dissipation casing of the candle lamp, so that the manufactured LED candle lamp is better in stability and smaller in light attenuation.
Description
Technical field
The present invention relates to the heat dissipation type lampshade that a kind of candle lamp is used, be mainly used in the decorative lighting place, belong to field of semiconductor illumination.
Background technology
Semiconductor lighting (LED) be described as the 4th generation lighting engineering, have numerous advantages such as energy-saving and environmental protection, long-life, response are fast, receive people's extensive attention, develop very rapidly, application is expanded rapidly.It is current that one worldwide to occur be the replacement upsurge of target to replace the traditional lighting light fixture; We can say that the traditional lighting light fixture is local; The figure that LED is just arranged; As: replace incandescent lamp, replace the fluorescent-lamp-type fluorescent tube, substitute Grille lamp etc. with the LED bulb lamp, replace incandescent lamp type candle lamp etc. with the LED candle lamp with panel light with the LED fluorescent tube.
Present various LED candle lamp assembly and technical scheme are all very similar: be made up of lamp holder, power supply, heat-dissipating casing, light source and transparent plastic article and other auxiliary material.Yet these candle lamps nearly all exist a common problem---heat dissipation problem; These candle lamps basically all are to rely on heat-dissipating casing to dispel the heat, yet because candle lamp in use, generally all is that light source, lampshade are last; Lamp holder and heat-dissipating casing etc. are following; The heat exchange pattern of whole candle lamp is: the heat that light source sends is transmitted to downwards on the heat-dissipating casing earlier, and heat-dissipating casing is transmitted in the air through modes such as radiation, convection current more then, therefrom can significantly find out; On the low side, and then caused the radiating effect of whole candle lamp to descend near near the position heat-dissipating casing heat radiation utilization rate the lamp holder.
Summary of the invention
The present invention is directed to the heat dissipation type lampshade that above-mentioned deficiency provides a kind of candle lamp to use; The heat dissipation type lampshade that this candle lamp is used is divided into metallic support part and transparent components light transmission part, when the heat dissipation type lampshade of using when this candle lamp is installed on the candle lamp; The heat dissipation metal shell of metal section and part and candle lamp is in contact with one another; The part heat can be transmitted to the metal section and part of the heat dissipation type lampshade that candle lamp uses, and is transmitted in the air, and whole candle lamp heat radiation is had tangible booster action.
The present invention adopts following technical scheme:
The heat dissipation type lampshade that a kind of candle lamp is used, as support frame, transparent components is as light penetrating object by the U-shaped metallic framework for described lampshade; Several U-shaped metallic frameworks support each other and form the half elliptic taper, and transparent components is arranged between each U-shaped metallic framework, and the outer surface of U-shaped metallic framework contacts with outside air.
The heat dissipation type lampshade that above-mentioned a kind of candle lamp is used; The quantity of wherein said U-shaped metallic framework is the 1-5 bar; Because every U-shaped metallic framework has certain influence to bright dipping; Therefore preferred U-shaped metallic framework quantity is the 2-3 bar, and the cross section of U-shaped metallic framework is a triangle in addition, can make the light that shines on the skeleton side reflex to the lampshade outside like this.
The heat dissipation type lampshade that candle lamp of the present invention is used; The outer surface of described U-shaped metallic framework is planar structure or has concaveconvex structure; Preferably have concaveconvex structure, can effectively increase the contact area of U-shaped metallic framework and air like this, promote radiating effect.
Beneficial effect
The heat dissipation type lampshade that a kind of candle lamp provided by the invention is used and existing candle lamp are used peels off or plastic lamp shade is compared; Increased metal section and part; This metal section and part can effectively improve the radiating effect of whole candle lamp; Metal shell heat radiation to candle lamp has good booster action, can effectively improve the stability of candle lamp.
Description of drawings
Fig. 1 is the structural representation of the heat dissipation type lampshade used of a kind of candle lamp provided by the present invention;
Fig. 2 is a candle lamp structural representation of having used the heat dissipation type lampshade that a kind of candle lamp provided by the present invention uses;
1 is the heat dissipation type lampshade that a kind of candle lamp is used among the figure, the 11st, and transparent components, the 12nd, U-shaped metallic framework, the 3rd, heat-dissipating casing, the 4th, lamp holder.
The specific embodiment
Below in conjunction with accompanying drawing to further explain of the present invention:
As shown in Figure 1: the heat dissipation type lampshade that a kind of candle lamp is used, as support frame, transparent components is as light penetrating object by the U-shaped metallic framework; Several U-shaped metallic frameworks 12 support each other and form the half elliptic taper, and transparent components is arranged between each U-shaped metallic framework 12, and the outer surface of U-shaped metallic framework 12 contacts with outside air.The quantity of U-shaped metallic framework 12 is 3.The outer surface of U-shaped metallic framework 12 is a planar structure or have concaveconvex structure, and the manufacturing approach of the heat dissipation type lampshade that this candle lamp uses is injection mo(u)lding, the heat radiation lampshade that U-shaped metal keel and transparent plastic article are made of one.
LED candle lamp as shown in Figure 2 comprises the heat-dissipating casing 3 that has fin, and driving power is fixed in the cavity of heat-dissipating casing, has lamp holder 4 to be fixed in the above at an end of heat-dissipating casing 3; Fixing and the welding of light source 2 is arranged above that at the other end; As required whether, can have the luminous intensity distribution annex on the light source 2, also can not have; The lampshade that will dispel the heat then covers on light source 2 tops, and is fixed on the heat-dissipating casing 3 and gets final product.
In the time of candle lamp work; Light source can generate heat, and wherein most heat spreads out of through heat-dissipating casing 3, is transmitted in the air; Some heat is transmitted on the U-shaped metal keel in the heat dissipation type lampshade through heat-dissipating casing in addition; Be transmitted in the air then, thereby promoted the radiating effect of light fixture, help to improve the reliability of light fixture.
