Abstract
The utility model refers to a kind of lamp and discloses a kind of LED lamp cap, which includes a cone-shaped lamp holder and a round substrate that is fixed on the cone-shaped lamp holder, wherein the round substrate is provided with multiple symmetric grooves at the periphery; the bottom of the round substrate is fixed with a LED drive board that connects each LED diode electrically; the cone-shaped lamp holder is connected to a transparent round lampshade above. The utility model is provided with features like high luminous efficiency and long service time after after the LED is installed.
Description
Technical field
The utility model relates to lamp, especially relates to the LED lamp holder that luminous efficiency is high, service time is long behind a kind of LED of installation.
Background technology
Lamp holder is meant the interface that is connected on the lamp cord end, supplies the installation bulb to use.The light source of installing on the lamp holder traditionally mainly is an incandescent lamp, but the incandescent lamp reliability is low, is opening switch in a flash, because the heavy current impact that the cold conditions filament resistance causes for a short time, and be prone to cause filament blow; Its luminous efficiency is low simultaneously; Incandescent lamp 1w also can only convert 20 lumen luminous energy at the most to now; Convert 300 lumen luminous energy theoretical values to according to the 1w electric energy, source efficiency n=20/300=6.67%, circuit efficiency is 100% (most incandescent lamp torches all is the circuit that leads directly to); Both additions are less than 10%, and most electric energy have all converted heat energy to; Bulb is along with battery increases service time, and brightness descends not too not severe; Totally the time, the brightness meeting drops to suddenly and can't use in battery, at this moment just needs to have changed battery.
Summary of the invention
For overcoming above-mentioned shortcoming, the utility model purpose is to provide the LED lamp holder that luminous efficiency is high, service time is long behind a kind of LED of installation.
The utility model is realized through following technical measures; A kind of LED lamp holder; Comprise conical lamp socket, be fixed on the circular substrate on the conical lamp socket, the periphery of this circular substrate is provided with the groove of a plurality of symmetries; The bottom of said circular substrate is fixed with the LED that is electrically connected each LED diode and drives mainboard, and said conical lamp socket top also is connected with a transparent circular lampshade.
As a kind of optimal way, said circular lampshade is threaded on the taper lamp socket.
As a kind of optimal way, the upper surface of said circular substrate is smooth and be coated with one deck reflector layer.
Concrete, said reflector layer is a fluorescence coating.
Concrete, said conical lamp socket is provided with the screw seat of three symmetries, and said circular substrate is provided with the screw hole of three relevant positions.
As a kind of optimal way, be provided with a waterproof washer between said circular lampshade and the taper lamp socket.
LED has changed the luminous and luminous principle of electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and adopts electroluminescence.According to one's analysis, the characteristics of LED are very obvious, and the life-span is long, light efficiency is high, radiationless and low-power consumption.The spectrum of LED almost all concentrates on visible light frequency band, and its luminous efficiency can surpass 150lm/W.LED and ordinary incandescent lamp, spiral energy-saving lamp and T5 three-color fluorescent lamp are compared, and the result shows: the light efficiency of ordinary incandescent lamp is 12lm/W, and the life-span was less than 2000 hours; The light efficiency of spiral energy-saving lamp is 60lm/W; Life-span, the T5 fluorescent lamp then was 96lm/W less than 8000 hours, and the life-span is approximately 10000 hours; Can surpass 150lm/W and diameter is 5 millimeters a white light LEDs light efficiency, the life-span can be greater than 100000 hours.The utility model uses LED as light source, thus make its life-span long, light efficiency is high, identical battery can use the longer time.
Description of drawings
Fig. 1 is the decomposition texture sketch map of the utility model.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is done further explain.
Like Fig. 1, a kind of LED lamp holder comprises threaded conical lamp socket 5; Conical lamp socket 5 is provided with the screw seat of three symmetries; And be fixed on the conical lamp socket circular substrate 3 that there are three screw holes that mate with the screw seat at the middle part through screw, and these circular substrate 3 upper surfaces are the fluorescent reflective layer, periphery is provided with the semi-circular recesses of 10 symmetries; Chucking has a LED diode 4 in each groove; The bottom of circular substrate 3 is fixed with the LED that is electrically connected each LED diode 4 and drives mainboard, and the conical lamp socket 5 tops transparent circular lampshade 1 that is threaded is provided with a waterproof washer 2 between circular lampshade 1 and the taper lamp socket 5.
More than be that the utility model LED lamp holder is set forth; Be used for helping to understand the utility model; But the embodiment of the utility model is not restricted to the described embodiments; Anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify, all should be the substitute mode of equivalence, be included within the protection domain of the utility model.
