Abstract
The utility model discloses an LED fluorescent lamp with a novel structure, which is a novel energy-saving illuminating device and comprises an LED luminous body, a shell, a power source and a control circuit board. The LED luminous body is mounted in the middle of a cup bottom and fixed onto the circuit board. The shell has a reflector cup structure by design. Emitted light is collimated and focused by means of installing a reflector cup, a module for optical design of the reflector cup is manufactured by means of micromachining, and the shape of the reflector cup can be used for controlling diffusion angles of the LED luminous body so that the emitted light is guided to a needed operating space. Simultaneously an AL (aluminum) film is evaporated on the inner surface of the reflector cup of the LED fluorescent lamp and can effectively improve emissivity of the light. The LED fluorescent lamp with the design and the structure has the advantages of high lighting effect, small volume, low heat resistance, fine heat dissipation and the like.
Description
Technical field
The utility model relates to LED energy-saving illumination field, and refering in particular to is a kind of LED fluorescent lamp of new structure.
Background technology
LED is the green illumination light source of 21st century, and the LED fluorescent lamp is following illumination development trend, and the power consumption of LED fluorescent lamp is about 1/3rd of traditional fluorescent lamp, and the life-span also is 10 times of traditional fluorescent lamp, and general service time is longer.The LED fluorescent lamp exists the light source utilization rate low at present, and defectives such as lack of homogeneity, these factors cause LED fluorescent lamp large tracts of land to promote relatively difficulty, and a kind of LED fluorescent lamp of new structure can overcome above-mentioned defective.
The utility model content
The technical problems to be solved in the utility model is that to overcome the light source utilization rate of LED fluorescent lamp low, and problems such as lack of homogeneity provide a kind of LED fluorescent structure of new structure.
For solving the problems of the technologies described above, a kind of LED fluorescent lamp of new structure comprises LED illuminator, shell, power supply and control circuit board, medium position at the bottom of it is characterized in that the LED illuminator is installed in glass, and the LED illuminator is fixed on the circuit board, shell adopts the reflecting cup structure design.
Improve as the progressive of technique scheme, its feature is that also the reflector of LED fluorescent lamp adopts paraboloid of revolution structure.Adopt this structural design, can export directional light, reduce the light rate to greatest extent.Distribution of light becomes evenly behind the common LED output beam process paraboloid of revolution reflecting condensation, concentrates.
Focus on by reflector being installed, being made the light collimation that sends, the model that the optical design of reflector is adopted processes by little, and its shape can be controlled the dispersion angle of LED illuminator, and the photoconduction that LED is sent is to desired working space.
As improvement of the technical scheme, the LED fluorescent lamp of described a kind of new structure, its reflector inner surface evaporation AL film can effectively improve the emissivity of light.
The beneficial effects of the utility model:
Tradition LED fluorescent lamp is directly poly-to being impossible together many LED light of so dispersing, and the light that must send each LED earlier pools directional light.So adopt the LED reflecting cup structure, can improve the utilization rate of light source so that efficient and rational the converging of the luminous energy that LED sends, and light source is reasonably focused on together, can solve light and penetrate problems such as inhomogeneous.Adopt the LED fluorescent lamp of this project organization, have the light efficiency height, volume is little, and thermal resistance is low, and characteristics such as good heat dissipation are following LED fluorescent lamp development trends.
Description of drawings
Fig. 1 is a kind of schematic diagram of LED fluorescent lamp of new structure
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
With reference to Fig. 1, the LED fluorescent lamp of described a kind of new structure comprises LED illuminator 1, shell 2, power supply 3 and control circuit board 4.LED illuminator 1, control circuit board 4 and power supply 3 are connected in series, and LED illuminator 1 is composed in series by 12 LED, and wherein the number of LED can be adjusted within the specific limits.Position at the bottom of LED illuminator 1 is installed in glass in 5, and with silica stationary on control circuit board 4.
LED illuminator 1 shell is a reflector, adopts paraboloid of revolution structure, can export directional light, reduces the light rate to greatest extent.Distribution of light becomes evenly behind the common LED illuminator output beam process paraboloid of revolution reflecting condensation, concentrates.After tested, behind the adding reflector, the directionality of LED is more intense, is the bat aerofoil profile, and the average intensity angle of flare is 97.1%, has the good luminous intensity distribution uniformity.At reflector paraboloid of revolution structure inner surface evaporation AL film, can effectively improve the emissivity of light simultaneously.
