Abstract
The utility model discloses a high-luminous efficacy LED daylight lamp, which comprises an aluminum heat radiating pipe (1) and a lamp screen (2). A PCB base plate (3) is arranged on the aluminum heat radiating pipe (1), a plurality of LED chips (4) are arranged on the PCB base plate (3), a lamp holder (5) is arranged at each of the two ends of the aluminum heat radiating pipe (1), and light-guide reflecting surfaces (6) are arranged on the aluminum heat radiating pipe (1) on the two sides of the LED chips (4). Because of the mentioned structure in which two light-guide reflecting surfaces (6) are additionally arranged on the two sides of the light-emitting surfaces of LED chip heat radiating pipe, the light emitted from the LED chips is partially refracted by the lamp screen, then reflected by the light-guide reflecting surfaces, and irradiated outside, thereby achieving the purpose of efficiently using the light source and improving the utilization efficiency of the light fitting. In addition, the high-luminous efficacy LED daylight lamp has the advantages of convenient fabrication, low fabrication cost, and so on, and has high practicability and value of generalization.
Description
Technical field
The utility model belongs to the technical field of led chip lighting, specifically is meant a kind of LED fluorescent lamp of high light efficiency.
Background technology
At present,, use more and more widely, be widely used on the led chip fluorescent lamp now in the room lighting field because led chip has advantages such as energy-saving and environmental protection, life-span length.Along with the development of led chip, its light efficiency is also more and more higher.But the led chip fluorescent lamp is only relied on the development of led chip light source at present, and does not develop in the utilization to led chip daylight light fixture, makes it produce higher Luminaire efficiency.
The utility model content
The purpose of this utility model is to provide a kind of led chip fluorescent lamp that improves the led chip light efficiency by ray refraction and reflection.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the LED fluorescent lamp of high light efficiency, comprise aluminium radiating tube and lampshade, be equiped with the PCB substrate on the described aluminium radiating tube, the PCB substrate is provided with several led chips, the two ends of aluminium radiating tube are provided with lamp holder, and described aluminium radiating tube is provided with the guide light reflection face in the both sides of led chip.
Post reflective sheeting on the described guide light reflection face.
Described guide light reflection face is the inclined-plane.
The axially parallel of described guide light reflection face and aluminium radiating tube.
Owing to adopted above-mentioned structure, increase by two groups of guide light reflection faces on the light-emitting area both sides of aluminium radiating tube, the light that is sent by led chip reflects through the guide light reflection face after lampshade partly reflects again, again to external exposure, can reach efficient use light source, increase the purpose of the utilization ratio of light fixture.The utility model also has advantages such as easily manufactured, low cost of manufacture in addition, has very strong practicality and promotional value.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the three-dimensional installation diagram of the LED fluorescent lamp of high light efficiency;
Fig. 2 is the sectional view of the LED fluorescent lamp of high light efficiency.
The specific embodiment
As shown in Figure 1 and Figure 2, the LED fluorescent lamp of high light efficiency described in the utility model comprises aluminium radiating tube 1 and lampshade 2, installs power supply unit in the aluminium radiating tube 1.In order to reduce the dazzle of the luminous generation of led chip, lampshade 2 is to adopt through the PC material of frosted to make, and reaching the purpose of soft light, will inevitably produce the part decay by the luminous light of led chip during through lampshade 2, in the refraction return pipe.Be equiped with PCB substrate 3 on the described aluminium radiating tube 1, PCB substrate 3 is provided with several led chips 4, the two ends of aluminium radiating tube 1 are provided with lamp holder 5, described aluminium radiating tube 1 is provided with guide light reflection face 6 in the both sides of led chip 4, guide light reflection face 6 can be one-body molded by aluminium radiating tube 1, stick reflective sheeting on its surface, light reflectance is good like this.Described guide light reflection face 6 is inclined-planes, the axially parallel of described guide light reflection face 6 and aluminium radiating tube 1.
During the utility model work, led chip 4 luminous light pass through lampshade 2 to external exposure, and light is refracted to guide light reflection face 6 on lampshade 2 tops, forms reflection on guide light reflection face 6, again to external exposure, can effectively utilize light source.
Use photoelectric comprehensive tester (integrating sphere) 19W1.2 rice led chip fluorescent lamp to be had the test respectively of guide light reflection face and no guide light reflection face, obtain a result and be: it is 1662 lumens that no guide light reflection face led chip fluorescent lamp is measured total output flow, every watt 87.47 lumen; Having guide light reflection face led chip fluorescent lamp not go out total output light flux is 1697 lumens, every watt 89.31 lumen, and every watt increases by 1.84 lumens.
In a word; though the utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
