Abstract

The utility model relates to a floodlight. The floodlight comprises a transparent lampshade with a standard lamp holder and a light source arranged in the transparent lampshade. The utility model has technical key points of that: the light source is a large power LED adopting a safe voltage, the breadboard of the control circuit of the LED is fixed on a radiator via a heat carrier, at a position where the surrounding wall of the transparent lampshade and the electronic components of the control circuit of the large power LED are corresponding is provided with ventilating holes, and the radiator passes by a thermal baffle and the breadboard of a power circuit first and then is fixed on a joint pin of the lamp holder chassis by making use of a bracket. With the reasonable structural design, the utility model has the advantages of energy-saving and long service life (these two advantages are also that of large power LED), marked enhancement of lighting effect and use safety and reliability.

Description

Energy-saving lighting lamp

Technical field

The utility model relates to the lighting source that a kind of daily life is used, and particularly a kind ofly is suitable for indoor safe and reliable energy-saving lighting lamp.Also be applicable to the general lighting or the illumination of common decoration in other place.

Background technology

At present, the lighting source that people's daily life is used is incandescent lamp mostly, the electricity-saving lamp that is adopted generally all be adopt have the transparent blister of standard lamp socket and assemble in it with tengsten lamp or the spot of filament as light source, its service life is greatly about about 1,000 hours to 2,000 hours; Also there is many pearls of employing light emitting diode to make as the electricity-saving lamp of decorating with illumination.But the brightness of common light emitting diode is lower, and also unstable, its attenuation rate is higher, and service life is lower.At the normal powerful light emitting diode that adopts a kind of 1W in the special place of voltage safe in utilization, the illuminance of this large-power light-emitting diodes is greater than the 40W ordinary incandescent lamp.Because of it adopts silicon chip as illuminator, thus with compare as the incandescent lamp of illuminator with tungsten filament, obviously improve its service life, greatly about 80,000 hours to 100,000 hours, it has characteristics energy-conservation, that the life-span is long under equal service condition.Yet in general lighting, also do not adopt the illuminating lamp of large-power light-emitting diodes as light source.

The utility model content

The purpose of this utility model provides a kind of energy-saving lighting lamp, and its reasonable in design except that the advantage of energy-conservation, the long service life with large-power light-emitting diodes, can also significantly improve the illuminating effect of lamp and the security reliability of use.

The purpose of this utility model is achieved in that this lamp band has the transparent blister of standard lamp socket and assembles its interior light source, its technical essential is: described light source is for adopting the large-power light-emitting diodes of safe voltage, the control circuit wiring board of this pipe is fixed on the radiator by heat carrier, the perisporium of described transparent blister is provided with ventilating heat dissipating hole with the corresponding part of the electronic component of the control circuit of this large-power light-emitting diodes, and radiator utilizes support together to be fixed on the joint pin on lamp socket chassis by thermal insulation board and power circuit wiring board.

Because lamp socket of the present utility model adopts the universal lamp holder of existing incandescent lamp, so can equally have interchangeability by the accurate bulb of image scale.Because of the light source of this lamp adopts large-power light-emitting diodes, so have the advantage of energy-conservation, the long service life of large-power light-emitting diodes.In addition, the perisporium of transparent blister is provided with ventilating heat dissipating hole with the corresponding part of the electronic component of the control circuit of this large-power light-emitting diodes, the control circuit wiring board is fixed on the radiator by heat carrier, the Btu utilization ventilating heat dissipating hole that sends in the electronic component course of work distributes rapidly, guaranteeing the normal operation of large-power light-emitting diodes, thereby significantly improve the illuminating effect of lamp and the security reliability of use.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is a kind of power circuit principle figure of the present utility model.

The specific embodiment

Describe concrete structure of the present utility model in detail according to Fig. 1-3.This lamp comprises the transparent blister 1 that has standard lamp socket 9 and assembles its interior light source.Wherein standard lamp socket 9 adopts the lamp socket of the standard screw socket that has ordinary incandescent lamp now or the lamp socket of standard socket.Transparent blister 1 useable glass that the chassis of making by the insulating materials that is fixed on the standard lamp socket 9 connects or transparent plastic processing, its shape should be determined according to actual instructions for use.Light source is the large-power light-emitting diodes 3 of existing employing safe voltage, the universal control circuit that the control circuit of this pipe adopts electronic component commonly used to form, its control circuit board 2 is fixed on the general aluminium alloy heat radiator of electronic component 12 by heat carrier 4, is beneficial to heat radiation.For heat is distributed as early as possible, the perisporium of transparent blister 1 is provided with ventilating heat dissipating hole 13 with the corresponding part of the electronic component of the control circuit of this large-power light-emitting diodes 3.Radiator 12 utilizes support 11 together to be fixed on the joint pin on chassis 10 of lamp socket 9 by thermal insulation board 6 and power circuit wiring board 7.The upper end of support 11 is fixed with the reflection light 5 that can increase large-power light-emitting diodes 3 brightness.Be assembled in the power circuit of forming by resistance R 1-R4, capacitor C 1-C5, diode D1-D7, triode Q1-Q2 and transformer T1-T2 etc. commonly used (as shown in Figure 3) on the power circuit wiring board 7, convert civil power 220V to safe voltage 4.5V output, as the dc source of the control circuit of large-power light-emitting diodes 3.The civil power 220V alternating current input of power circuit is connected the positive terminal of standard lamp socket 9 segregate bottom metal 8 by lead, and the safe voltage 4.5V DC output end that converts to of power circuit is connected the metal screw socket of standard lamp socket 9 or the negative pole end of socket by lead.

The using method of this energy-saving lighting lamp is identical with existing ordinary incandescent lamp.

Claims

1, a kind of energy-saving lighting lamp, comprise the transparent blister that has the standard lamp socket and assemble its interior light source, it is characterized in that: described light source is for adopting the large-power light-emitting diodes of safe voltage, the control circuit wiring board of this pipe is fixed on the radiator by heat carrier, the perisporium of described transparent blister is provided with ventilating heat dissipating hole with the corresponding part of the electronic component of the control circuit of this large-power light-emitting diodes, and radiator utilizes support together to be fixed on the joint pin on lamp socket chassis by thermal insulation board and power circuit wiring board.
