Abstract
The utility model discloses an LED lamp. The LED lamp comprises a lamp holder (4), a radiating component and an LED light source, wherein the radiating component is connected onto the lamp holder (4), and the LED light source is mounted on the radiating component. The LED lamp is characterized in that the radiating component comprises a plastic base and plastic fins (3) which are arranged on the plastic base. According to the LED lamp, prejudices in the technical field are overturned, and a cylinder and the plastic fins are used as the radiating component, accordingly, the structure of the LED lamp is simplified, the radiating efficiency of the LED lamp is improved, the LED lamp is light, the temperature of the LED light source can be effectively controlled, and the product utilization effect is improved.
Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of LED lamp.
Background technology
For energy conservation and environment protection, reduce energy resource consumption, mainly promote the LED lamp of energy-conserving and environment-protective at lighting fields such as family, street lamps.But the reason that present LED lamp is difficult to promote has the following aspects: one, because heat dissipation technology is poor, cause the temperature height of LED lamp, light decay is serious in the use, phenomenons such as electronic original part is aging influence is normal to be used, then shorten the service life of LED light fixture when serious, more can cause chip to burn when temperature surpasses 60 ℃; Its two, in order to improve radiating effect, adopt the aluminium pedestal heat radiation of good heat dissipation effect, though the aluminium pedestal has heat conductivility preferably, facts have proved that its radiating effect is not good, and the consumption aluminium is unfavorable for energy-saving and emission-reduction more, the production cost height, assembling is complicated and heavy.
Summary of the invention
In view of this, the utility model provides a kind of radiating effect good, light LED lamp.
The purpose of this utility model is achieved through the following technical solutions: a kind of LED lamp, comprise lamp holder, be connected radiating subassembly on the lamp holder, be installed in the led light source on the radiating subassembly, described radiating subassembly comprises plastic base and is arranged on plastics fin on the plastic base.
Described lampshade can select for use light transmissive materials such as glass or plastics to make.The heat dispersion that it has been generally acknowledged that plastic material is relatively poor, and the designer finds to have better heat dispersion though the plastic material heat-conducting effect is not good in practice.So the utility model has selected for use plastic base and plastics fin to replace aluminium matter fin of the prior art as the radiating subassembly of LED lamp.The plastics fin has bigger surface area, and thermal convection current efficient height can effectively be controlled LED light pipe operating temperature, and it is too high and produce problems such as light decay, life-span reduction to solve LED light pipe Yin Wendu.Simultaneously, use plastics fin replacement aluminium matter fin can also be saved the consumption of raw materials in the LED light pipe production process.In addition, plastic material has water resistance, the insulating properties that are better than aluminium matter thermal component especially, is conducive to strengthen the job stability of LED lamp in wet environment, prevents electric leakage.
Described plastic base is the cylinder of hollow; Described plastics fin equidistantly arranges along cylinder sides, and described plastics fin and plastic base are one-body molded.
The plastic cylinder of hollow is conducive to promote air to flow, and is light and have better heat dispersion, can further control the temperature in the use of LED lamp, prolongs the service life of heat radiating LED lamp, improves its result of use.Plastics fin and plastic base are one-body molded, are conducive to simplify production process, can economize in raw materials effectively simultaneously.
Described its width of plastics fin dwindles from the top down gradually.
According to designer's experimental analysis, more far away apart from led light source, the thermolysis of plastics fin is more low.Therefore suitably reduction is apart from the width of LED installed surface plastics fin at a distance, and the volume that is conducive to save material and control LED lamp does not influence the function that it controls temperature with weight.
The quantity of described plastics fin is the 10-20 sheet.
Described cylinder radius-thickness ratio is 1:20-1:30.
Because not as good as aluminium, having only, the heat conductivility of plastic material reduces its thickness to improve heat transfer efficiency.The reduction of cylinder thickness will cause mechanical strength not enough and damaged easily, influence service life.The utility model is optimized the radius-thickness ratio of cylinder, makes it to possess enough intensity and heat transfer efficiency simultaneously.
Heat radiating LED lamp provided by the utility model has following technique effect:
1. the utility model has been overturned the prejudice in the technical field, adopt cylinder and plastics fin as radiating subassembly, simplified the structure of LED lamp, the radiating efficiency that improves the LED lamp makes it lighter simultaneously, can control the temperature of led light source effectively, improve the result of use of product.
2. the utility model is optimized the shape of plastics fin, saves the purpose that raw materials for production are realized energy-conserving and environment-protective effectively.
3. the utility model is optimized the radius-thickness ratio of cylinder, makes it to satisfy simultaneously the requirement of radiating efficiency and mechanical strength.
4. cylinder of the present utility model and plastics fin are formed in one, and processing is simple, and is with low cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Describe in further detail for the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and the utility model of embodiment:
Present embodiment provides a kind of LED lamp, as shown in Figure 1, comprise lamp holder 4, be connected radiating subassembly on the lamp holder 4, be installed in the led light source on the radiating subassembly, it is characterized in that: described radiating subassembly comprises plastic base and is arranged on plastics fin 3 on the plastic base.
Above-mentioned led light source lower end also is provided with reflector layer.
In the present embodiment, above-mentioned plastic base comprises that 2,14 radiating fins 3 of cylinder of a hollow are equally distributed on cylinder 2 outer walls.
Above-mentioned cylinder 2 and plastics fin 3 can adopt common on the market raw material to make, and the utility model uses the one-body molded mode of Merlon to prepare cylinder 2 and plastics fin 3.
Above-mentioned plastics fin 3 its width dwindle from the top down gradually.
In addition, described cylinder 2 radius-thickness ratios are 1:25.
Present embodiment selects for use cylinder and plastics fin to form the temperature of radiator structure control led light source, has economical with materials, light, result of use that radiating effect is good.
More than be wherein specific implementation of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
