A kind of without driving LED reflectoscopeTechnical field
The utility model relates to LED field of illumination lamp technology, is specifically related to a kind of without driving LED reflectoscope.
Background technology
LED light source as green, energy-conservation, power saving, long-life the 4th generation lighting and be a dark horse, extensively concerned,Develop rapidly in high gear. Current LED light source is the semiconductor devices of low-voltage, large current work, and it is suitable to provideDirect current stream could be normally luminous. The luminous technology of direct drive LED light source is more and more ripe, due to our normal lightingThe power supply using is high-voltage alternating (AC100～220V), thus must obtain lower voltage by the technology of step-down, conventionalBe transformer or Switching Power Supply step-down, then exchange conversion is become to direct current, then is transformed into DC constant current power supply, just can impel LEDLight source luminescent. Therefore in the LED light fixture of prior art, must there is certain space to settle driver module, cause with drivingThe common complicated structure of LED lamp, and manufacturing cost is relatively high, and the lamp body of existing a lot of LED lamps is traditionalThe metal materials such as aluminium, insulating properties are bad and can not resist high pressure, also have some LED lamps in luminescence process, to have the feelings of stroboscopicCondition easily causes damage to user of service's eyesight for a long time under such LED lamp environment.
Utility model content
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides a kind of without driving LED reflectoscope, noDemand motive device, realizes AC and directly accesses civil power, simple in structure, low cost of manufacture, and service life is longer.
The utility model is for solving the problems of the technologies described above, and the technical scheme providing is: a kind of without driving LED reflectoscope,The lamp holder and the AC LED lamp that comprise the cup-shaped lamp body of glass material, be threaded with lamp body tail end, establish the inside of described lamp bodyBe equipped with luminous lens, the inwall of lamp body be provided with for by the light reflection of LED lamp to dead ahead reflector layer, the weldering of described LED lampBe connected on aluminium base, the pin of LED lamp drives the output of chip to be electrically connected with the non-transformer LED being welded on aluminium base, nothingPower LED drives the input of chip and the corresponding electrical connection of the binding post of lamp holder, is also welded with electrolysis electricity on described aluminium baseHold, the positive pole of electrochemical capacitor is electrically connected with LED lamp, the minus earth of electrochemical capacitor
As a kind of further improvement without driving LED reflectoscope of the utility model: the lamp holder of described LED reflectoscope isGU10, GU5.3, E14, E27, E26 or B22.
Beneficial effect
1, not demand motive device of LED reflectoscope of the present utility model, can realize AC and directly access civil power, simple in structure,Low cost of manufacture, convenient installation, has reduced some problems that occur in use procedure, and service life is longer;
2, the lamp body material of LED reflectoscope of the present utility model is glass, has reduced manufacturing cost, than traditional aluminium etc.Metal material can reach a better insulating effect, can resist high pressure; Glass lamp body inside is provided with reflector layer, can handleLED light reflection, to dead ahead, is realized directional illumination, improves light efficiency, reaches the effect of energy-conserving and environment-protective;
3, LED reflectoscope of the present utility model has increased electrochemical capacitor on circuit board, realized luminous without stroboscopic, canBetter reduce visual fatigue.

Detailed description of the invention
As shown in Figure 1: a kind of without driving LED reflectoscope, comprise the cup-shaped lamp body 1 of glass material, with lamp body 1 tail end screw threadThe lamp holder 3 and the AC LED lamp 4 that connect, the outer surface of glass lamp shade 2 is sphere curved surface, the lamp holder 3 of LED reflectoscope can be adoptedWith GU10, GU5.3, E14, E27, E26 or B22, the inside of described lamp body 1 is provided with luminous lens 2, the inwall setting of lamp body 1Be useful on the light reflection of LED lamp 4 to dead ahead reflector layer, described LED lamp 4 is welded on aluminium base, the pin of LED lamp 4Drive the output of chip to be electrically connected with the non-transformer LED being welded on aluminium base 5, non-transformer LED drives the input of chipThe corresponding electrical connection of binding post with lamp holder 3, is also welded with electrochemical capacitor, the positive pole of electrochemical capacitor and LED on described aluminium baseLamp 4 is electrically connected, the minus earth of electrochemical capacitor, and it is luminous without stroboscopic that electrochemical capacitor can be realized LED lamp, can better reduce visionTired.
LED lamp of the present utility model on the one hand, can be realized AC and directly access civil power, simple in structure, and low cost of manufacture is convenientInstall, reduced some problems that occur in use procedure, service life is longer; On the other hand, the lamp body material of reflectoscope isGlass, reduce manufacturing cost, can reach a better insulating effect, Ke Yikang than metal materials such as traditional aluminiumHigh pressure; Glass lamp body inside is provided with reflector layer, can, LED light reflection to dead ahead, realize directional illumination, improves light efficiency, reachesTo the effect of energy-conserving and environment-protective; And reflectoscope has increased electrochemical capacitor on circuit board, realized luminous without stroboscopic, Ke YigengGood minimizing visual fatigue.
