Description

A kind of LED lighting

Technical field

The utility model relates to a kind of lighting, especially a kind of LED lighting.

Background technology

LED has been trend of the times as the lighting source in future, but because the particularity of LED components and parts, in actual applications, LED also has some questions of substance to need to solve as lighting source, and wherein, distinct issues are exactly the problem of heat radiation the most; Because LED in use can produce certain heat, if these heats do not distribute in time, the luminous efficiency of LED is descended, cause the light decay of LED, have a strong impact on the service life of LED.

For this reason, in actual applications, usually adopt the radiating piece of making by metal material to come LED is dispelled the heat such as aluminum alloy materials, with the LED fluorescent lamp is example, at present, the most typical, also the most general using method is that the cross section of directly making with metal material is the mounting base of the radiating piece of C type or D type as the circuit board of LED lamp, in the front of LED lamp is light-emitting area to adopt transparent cross section be the plastic lamp shade of C type, by the radiating piece of C plastic lampshade and C type or D type spiral-lock and constitute a complete fluorescent tube in opposite directions; It exists shortcoming to be: because the heat conductivility of plastic material lampshade is poor, the temperature of failing in the use apace the LED lamp to be produced is transmitted to the outside, makes the radiating effect of LED lamp be subjected to influence to a certain degree; In addition, when light passes through plastic material, can produce decay to a certain degree, with general PC material is example, and its light transmittance only is 86～90%, and more fatal is, the light transmittance of plastic material can make the LED lamp produce light decay indirectly along with the prolongation of service time by reducing temporarily; In addition, because the metal heat sink of the pedestal of the circuit board of conduct installation LED lamp is directly externally exposed, might cause leaking electricity even the generation electric shock accidents.

Summary of the invention

The purpose of this utility model is at the problems referred to above, a kind of good heat conductivity, light transmittance height are provided, improve illuminating effect, LED lighting safe in utilization.

The technical scheme that the utility model is realized is: a kind of LED illuminating lamp tube, comprise LED lamp, circuit board, electronic driver, metal heat sink, lampshade and lamp holder, the circuit board that the LED lamp is installed is fixed on the metal heat sink, this lampshade is a glass lamp, and metal heat sink is placed in the cylindrical shell of glass lamp and with the inwall contact of glass lamp and is connected.

The utility model, metal heat sink can be that cross section is the metal heat sink of C type.

The utility model, metal heat sink also can be that cross section is the metal heat sink of D type.

The utility model, metal heat sink can also be that cross section is the metal heat sink of ∏ type; Certainly, be not limited to above-mentioned cross section structure, can adopt other various cross section structures as required, such as the H type.

The utility model can be reserved with the installing hole that is used for fastening lamp holder in the two ends of metal heat sink, makes the lamp holder of lamp tube ends can be fastening with it with screw, for later maintenance work provides great convenience; Certainly, also can make the mode of connecing that sticks with glue as required.

The utility model can be reserved for position, hole and position, hole enclosing cover that screw is installed at lamp holder; Holding screw is installed in Kong Weizhong, after installing, covers position, hole enclosing cover, makes the outside of fluorescent tube can't see holding screw, makes overall appearance generous.

The utility model, electronic driver are similar to the ballast of traditional fluorescent lamp, can be built in lamp interior, also can be connected the lamp holder place, can also be external in the outside any suitable place of light fixture.

The another kind of technical scheme that the utility model is realized is: a kind of LED lighting bulb, comprise LED lamp, circuit board, electronic driver, metal heat sink, lampshade and lamp holder, the circuit board that the LED lamp is installed is fixed on the metal heat sink, this lampshade is a glass bulb, and metal heat sink is placed in the cylindrical shell of glass bulb and with the inwall contact of glass bulb and is connected.

Good effect of the present utility model:

The heat that is produced when 1), the LED lamp is worked, the back side conducts to the inwall of glass lamp by metal heat sink, utilize glass lamp that heat is transmitted to the external world rapidly, the heat in LED front is then absorbed by the glass in front by heat radiation and externally transmits rapidly, because the heat transfer property of glass is better than plastics far away, so its radiating effect has improved much than the scheme of using the plastic-aluminum combination; In addition, the light transmissibility of glass lamp also exceeds 8～10% than plastic products, so, can improve the light output efficiency of fluorescent tube greatly, the more important thing is that glass tube can not produce the phenomenon that light transmittance descends because service time is long;

2), because metal heat sink places the inside of glass tube, the metal part thoroughly isolated with the external world, solved effectively that metal heat sink exposes and the safety problem that causes.

The utility model has good heat conductivity, light transmittance height, improves illuminating effect, advantage safe in utilization.

Following embodiment accompanying drawings is further described the utility model.
