Abstract

The utility model discloses a light-emitting diode (LED) lighting lamp applied to a tunnel. The LED lighting lamp is mainly formed by a power supply, light expanding covers, LED sunlight lamps, an aluminum substrate, plugs and radiators. The lamp comprises a constant current control chip, a series of LED sunlight lamps are connected in series in the aluminum substrate, a stabilizing diode is respectively connected at two ends of each LED sunlight lamp in parallel, the light expanding covers are all arranged outside the LED sunlight lamp, the plugs are fixedly installed at two ends of the aluminum substrate, and the radiators are copper plates arranged on two sides of the aluminum substrate. Each branch of the lamp is driven by 20mA constant current, so that the LED lighting lamp is excellent in stabilizing performance and has no problems of electromagnetic compatibility and electromagnetic radiation. Each branch of LED sunlight lamps are connected in series and singly controlled by a constant current chip, and danger caused by uneven distribution of current in parallel connection circuits is completely avoided. The LED lighting lamp adopts the way that the copper plates are covered on two sides of the aluminum substrate, utilizes high head conduction coefficient of copper to quickly lead out temperature junction of LEDs and effectively resolves the radiating problem.

Description

A kind of LED lighting that is applied to the tunnel
Technical field
The utility model belongs to the LED field of illumination lamp technology, relates to a kind of LED lighting that is applied to the tunnel specifically.
Background technology
Power factor (PF) has Compulsory Feature for the high-power illumination light fixture, and the power factor (PF) height is carried for the electric power of power department just can practice thrift cost, but does not have big influence for the metering of energy unit active watt-hour meter.The tunnel illumination light fixture is exactly a kind of high-power illumination light fixture, in order to improve the power factor (PF) of high-power illumination light fixture, all just can bring up to more than 0.95 at a PFC rectification chip of installation on the lighting and tens peripheral electron components and parts in the prior art.Yet increase power factor (PF) and can bring some negative effects: as improve the electrical source consumption power 10% of whole lamp, the luminous efficiency that reduces light source, reduction luminous flux and increase material cost, this is disadvantageous for reaching the energy-conservation company that recoups the investment with income through the electricity charge of practicing thrift.And increase the electronic devices and components that PFC corrects chip and improved the probability that the LED driving power damages, influence the service life of light fixture.How can provide a kind of LED lighting that is applied to the tunnel simple in structure, with low cost, long service life to become the urgent demand of people.
Practical fresh content
The utility model is in order to overcome the deficiency that prior art exists, and a kind of LED lighting that is applied to the tunnel of simple in structure, with low cost, long service life is provided.
The utility model is realized through following technical scheme: a kind of LED lighting that is applied to the tunnel; It mainly is made up of power supply, expansion light shield, LED fluorescent lamp, aluminium base, plug and radiator: the said LED lighting that is applied to the tunnel also comprises a constant current control chip; One group of LED fluorescent lamp of series connection in aluminium base; All be parallel with a Zener diode at the two ends of each LED fluorescent lamp; Outside each LED fluorescent lamp, be provided with one and expand light shield, be installed with a plug respectively at the two ends of aluminium base, radiator is the copper coin that is arranged at the aluminium base both sides.
In aluminium base, be in series with 20~40 LED fluorescent lamps.
Expand the square expansion light shield that light shield is aluminized for the surface.
The rated power of every LEDs fluorescent lamp is 27W, adopts fluorescent lamp that the LED fluorescent lamp of 27W substitutes traditional 58W to be transported to power cable between the lamp stand circuit for the power department electric wire and need not any change and can meet the demands.
The regulation power factor (PF) is 0.75 in the draft standard for discussion of the LED fluorescent lamp of country, and the power factor (PF) of the utility model is 0.8, meets the standard that country formulates fully.
The beneficial effect of the utility model is: the utility model adopts the constant current control chip of U.S.'s import; Every road constant current 20mA is driven; Stability is splendid, and this constant-current source circuit does not have the switch oscillating circuit, makes the utility model not have the problem of electromagnetic compatibility electromagnetic radiation extremely.Connecting entirely in each road of whole LED fluorescent lamp, by the control of constant current control chip, has thoroughly stopped the harm that the parallel circuit electric current distributes inequality to cause in the LED fluorescent lamp commonly used separately.Cause the consequence that does not all work for preventing that a LEDs chip damages in the series circuit; Voltage-regulator diode protection of a 4.2v of parallel connection all at the two ends of every LEDs fluorescent lamp; Any chips damages; Electric current can pass through the voltage-stabiliser tube bypass, has thoroughly solved the drawback of LED lamp series circuit in the prior art.
Heat radiation is the key factor of decision LED fluorescent lamp light decay, and the life-span key that low-power LED will guarantee is that can junction temperature effectively be transmitted on the radiator.Generally available technology adopting is aluminium base pulls making, but one deck insulation film is arranged on the aluminium base, and this layer insulation film is macromolecular organic compound; Heat conduction is extremely slow; Therefore though it is pretty good to look that aluminium base seems radiating effect, in fact is hampered by this layer insulation film, the junction temperature of LED is still very high.The utility model is employed in the mode of aluminium base both sides copper-clad plate, utilizes the high thermal conductivity coefficient of copper rapidly the junction temperature of LED to be derived, and has effectively solved heat dissipation problem.
Description of drawings
Fig. 1 is a kind of structural representation that is applied to the LED lighting in tunnel of the utility model;
Wherein: the 1-power supply; 2-expands light shield; The 3-LED fluorescent lamp; The 4-aluminium base; The 5-plug; The 6-radiator.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1; A kind of LED lighting that is applied to the tunnel; It mainly is made up of power supply 1, expansion light shield 2, LED fluorescent lamp 3, aluminium base 4, plug 5 and radiator 6: the said LED lighting that is applied to the tunnel also comprises a constant current control chip; 30 LED fluorescent lamps 3 of series connection all are parallel with a Zener diode at the two ends of each LED fluorescent lamp 3 in aluminium base 4, outside each LED fluorescent lamp 3, are provided with one and expand light shield 2; Be installed with a plug 5 respectively at the two ends of aluminium base 4, radiator 6 is for being arranged at the copper coin of aluminium base 4 both sides.Expand the square expansion light shield that light shield 2 is aluminized for the surface, the rated power of every LEDs fluorescent lamp 3 is 27W.The utility model is effectively verified its reliability in specifically using, uninterruptedly lighted in 24 hours to install in intra-company and try out, and the illuminations actually measured sustainment rate is greater than 0.95 after 2 years.
Should be noted that at last; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
