Abstract

The utility model discloses a light emitting diode (LED) lamp and relates to an improvement on the structure of the LED lamp. The LED lamp comprises a lamp holder, a base, a housing and a lamp bulb shell, wherein the housing is a heat dissipation housing; and an LED circuit board is arranged on the base. The LED lamp is characterized in that: an alternating-current light emitting diode (ACLED) light source, an alternating-current driver, and two lead wires which are directly connected with the alternating-current driver are arranged on the circuit board, and heat dissipation holes are formed in the circuit board. By the ACLED light source, the circuit is not provided with a capacitor and a transformer which are easy to damage, so that elements and the circuit are simple, the fault rate is reduced greatly, and the potential safety hazard is avoided; therefore, the LED lamp has high safety and long service life and is really energy-saving and environment-friendly.

Description

A kind of LED lamp

Technical field

The utility model relates to a kind of architecture advances of LED lamp.

Background technology

LED is a kind of semiconductor that can electric energy be converted into visible light, at present, uses the light fixture of LED as light source, has the various places that advantages such as luminous efficiency height, energy-saving and environmental protection are widely used in people's life with it, but there is also following defective:

1, in LED when work,, because caloric value is big, it is slow dispel the heat, is easy to cause in the drive circuit electric capacity and transformer or LED itself to burn, and lack service life, and have potential safety hazard;

2, LED can only work under the DC direct current usually, therefore needs inside or outside current transformer that alternating current is converted into direct current, and this current transformer promptly increases the cost of LED lamp, has reduced the service life of LED again, thereby influences the product quality of light fixture;

3, in the existing LED light fixture owing to be provided with easy loss elements such as electric capacity and transformer, make the circuit more complicated, and in case wherein arbitrary element breaks down, then whole light fixture can not use all.

The utility model content

The utility model is exactly to the problems referred to above, provides that a kind of security is good, circuit simple, the LED lamp of long service life and energy-conserving and environment-protective.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The utility model comprises lamp holder, base, housing and bulb shell; Described housing is the heat radiation shell; Described base is provided with the led circuit plate, its structural feature be circuit board be provided with ACLED light source, louvre, ac driver and with direct-connected two leads of ac driver.

Preferably, back of circuit board is provided with heat sink.

Preferably, the led circuit plate is an aluminium base.

The beneficial effect of the utility model:

Have the good and long service life of security: the utility model adopts the ACLED light source; No perishable electric capacity and transformer are in circuit, and element and circuit summary are compared with general direct current DCLED; Fault rate can significantly reduce; There is not potential safety hazard,, and can really reaches the long-life of LED element more than 30000 hours so security is good;

Simple and the cost economy of circuit: the AC that the utility model need not account for volume changes DC transformer circuit element, not only can simplify circuit, and can alleviate the volume and weight of LED light fixture, reduces cost, and is easy to large tracts of land and promotes;

Energy-conserving and environment-protective: the utility model can reach minimum circuit energy loss, and heat dissipation design makes the LED light decay significantly reduce easily, thereby realizes real environmental protection and energy saving;

Be easy to promote: because the utility model adopts the ACLED light source, can directly be electrically connected, and not have electric capacity and transformer rapid wear power consumption circuit component with the city, thus be applicable to the big environment of line voltage variation, not fragile, be easy to marketing.
