Description

The LED electricity-saving lamp

Technical field

The utility model relates to the power lighting equipment technical field, exactly relates to a kind of illuminating lamp that is applicable in high-tension switch cabinet or the box-type substation cabinet.

Background technology

In power system, usually the cabinet intraoral illumination of high-tension switch cabinet or box-type substation adopts the ordinary incandescent lamp of 25W-40W, be CN201666502U as publication number, the Chinese patent literature that open day is on December 8th, 2010 discloses a kind of switch cabinet intraoral illumination lamp, comprise pedestal, lamp socket, bulb and protective cover, bulb is arranged on the lamp socket, lamp socket is arranged on the pedestal, protective cover is installed on the pedestal, hard-wired chute flexibly connects on the pulley that described lamp socket is installed bottom lamp socket and the pedestal, the two-stage of bulb connects the sheet metal that the lamp socket lower end arranges by lead, pedestal upper hopper chute end is provided with for the metal intermediate plate that is connected with sheet metal, and the metal intermediate plate is connected with external power source by lead.

But the thing followed, incandescent lamp power is big, and heating is serious, and the life-span, short drawback highlighted day by day, and along with high the rising of the energy-saving and cost-reducing cry of the whole society, incandescent lamp will be eliminated gradually, and the green energy conservation illumination more becomes the illuminating industry new lover.In addition, the mains lighting supply of high-tension switch cabinet is alternating current, but power supply is direct current when interruption maintenance, and common electricity-saving lamp volume is bigger than normal can't put into cabinet internal standard lamp housing, and electricity-saving lamp only adapts to AC power and can't adapt to direct current.

Therefore, under the background that incandescent lamp is progressively eliminated, how to find a kind of brand-new upgrading substitute products? not only will satisfy energy-saving and cost-reducing requirement, volume is small and exquisite again simultaneously, and can satisfy two kinds of different power supplys of AC and DC.This is current urgency problem to be solved.

Summary of the invention

The utility model is intended at above-mentioned existing in prior technology energy consumption height, bulky technical problem, the LED electricity-saving lamp that uses in a kind of switch cubicle or the transformer station's cabinet is provided, the utility model energy consumption is low, volume is little, and can use the power supply of AC and DC power supply simultaneously.

The utility model is realized by adopting following technical proposals:

A kind of LED electricity-saving lamp is characterized in that: comprise a plurality of LED lamp pearls, aluminium base and constant-current driven module, a plurality of LED lamp pearls are cascaded and are welded on the described aluminium base, and constant-current driven module is electrically connected with LED lamp pearl.

The LED lamp pearl of telling is three, and three LED lamp pearls are symmetrical triangle at aluminium base and arrange.

Described LED lamp pearl is pasted and is welded on the aluminium base, and LED lamp pearl center exposed part is close on the aluminium base by heat-conducting silicone grease.

Compared with prior art, the beneficial effects of the utility model show:

1, in the utility model, adopt the bead weld of LED lamp to be connected on the aluminium base, LED lamp pearl replaces existing incandescent lamp by the constant-current driven module ways of connecting, has following technique effect: low in energy consumption, and only be 12% of ordinary incandescent lamp power consumption under the same brightness; The light efficiency height, the light efficiency of LED bulb is 8-11 times that ordinary incandescent lamp steeps under the equal-wattage; Life-span is long, and the average life span of LED bulb was more than 30 times of ordinary incandescent lamp life-span more than 30000 hours; The appearance design exquisiteness is small and exquisite, is adapted at installing in the standard lampshade.

2, because the utility model adopts LED lamp pearl and constant-current driven module ways of connecting, constant-current driven module is LED lamp pearl field device commonly used, and constant-current driven module adapts to the power supply of AC and DC power supply.Therefore, the utility model can adapt to AC power and two kinds of power supply modes of dc source.

3, in the utility model, adopt three LED lamp pearls to be symmetrical triangle at aluminium base and arrange, three LED lamp pearls have increased brightness of illumination on the one hand, and arrange can the better utilization space for triangular symmetry simultaneously, and radiating effect is also better simultaneously.

4, in the utility model, LED lamp pearl is pasted and is welded on the aluminium base, and LED lamp pearl center exposed part is close on the aluminium base by heat-conducting silicone grease, and the heat that such mode can make the lamp pearl distribute conducts to aluminium base by heat-conducting silicone grease rapidly and dispels the heat.

Description of drawings

The utility model is described in further detail below in conjunction with specification drawings and specific embodiments, wherein:

Fig. 1 is structural representation of the present utility model

Fig. 2 is electrical schematic diagram of the present utility model

Mark among the figure:

1, LED lamp pearl, 2, aluminium base, 3, constant-current driven module.

The specific embodiment

Embodiment 1

As preferred forms of the present utility model, with reference to Figure of description, the utility model comprises 3 LED lamp pearls 1, aluminium base 2, constant-current driven module 3.1 series welding of LED lamp pearl is connected on the aluminium base 2, and constant-current driven module 3 is connected to the head and the tail of LED lamp pearl 1.LED lamp pearl 1 is symmetrical triangle at aluminium base 2 and arranges.The lamp pearl is arranged evenly can the better utilization space, and radiating effect is also better simultaneously.

LED lamp pearl 1 is pasted and is welded on the aluminium base 2, and it is that heat that the lamp pearl is distributed can conduct to aluminium base 2 by heat-conducting silicone grease rapidly and dispels the heat with, effect that lamp pearl center exposed part is close to aluminium base 2 by heat-conducting silicone grease.

Embodiment 2

As the comparatively simple embodiment of the utility model one, LED lamp pearl 1 is two, four or a plurality of, evenly is welded on the aluminium base 2 and gets final product.All the other are with embodiment 1, and constant-current driven module 3 is this area LED constant-current driven module 3 commonly used, and the product type of producing as Shanghai continuous heavy rain leaf Microtronics A/S is SHT6088 series constant-current driven chip.
