Abstract

The utility model discloses an LED light emitting module, which includes a glass core column and two circuit boards, wherein two circuit boards fixed together in a crossed manner, a lead is introduced out from the inside of the glass core column, the lead is welded and fixed with the lower end of one of the circuit boards, a cross circuit board is fixed at the tops of the two circuit boards, the plane where the two circuit boards are arranged are perpendicular to the plane where the cross circuit board is arranged, and a plurality of LED chips are welded on the two crossed circuit boards and the cross circuit board. According to the utility model, the two circuit boards are fixed together through inserting in a crossed manner, and the cross circuit board is further arranged at the tops of the two circuit boards, so that the LED chips fixed on the circuit boards enlarge the illumination area, the illumination without blind area is formed, and the service life can be prolonged; the energy consumption is lowered; and the LED light emitting module can be used in various LED lamps, and can replace 15-45 W filament lamps.

Description

The LED illuminating module

Technical field

The utility model relates to the LED technical field, particularly a kind of LED illuminating module that can be used for various LED light fixtures.

Background technology

Energy-saving and emission-reduction are focuses that the world today pays close attention to, because the fast development of LED, replacing incandescent lamp with LED is inexorable trend.

But LED has the not high shortcoming of lighting angle, and its lighting angle is limited, can make LED form lighting blind zone in some zone on every side; Influenced its illuminating effect; Though it is energy-conservation that it can be accomplished, and the life-span is long, and illumination effect does not reach the effect of incandescent lamp sometimes.

The utility model content

The utility model has overcome the deficiency that exists in the above-mentioned prior art, and a kind of lighting angle that increases is provided, and enlarges the LED illuminating module of range of exposures.

The technical scheme of the utility model is achieved in that

A kind of LED illuminating module; Comprise glass stem and two wiring boards, two wiring board right-angled intersections are fixed together, and in glass stem, draw lead; Lead is with wherein a wiring board lower end welding is fixing; Be fixed with a cross wiring board at the top of two wiring boards, two residing planes of wiring board are all vertical with the residing plane of cross wiring board, on the wiring board of two right-angled intersections and cross wiring board, all are welded with a plurality of led chips.

As preferably; In the middle of described two wiring boards; Wherein wiring board first half central authorities are provided with the breach that vertically is provided with together, and another piece wiring board Lower Half central authorities correspondence is provided with the breach that vertically is provided with together, two wiring boards breach through correspondence be inserted in together and welding fixing.

Adopted the principle of the utility model of technique scheme to be:

The utility model is two wiring boards to be the right-angled intersection grafting be fixed together, and also is provided with a cross wiring board at two wiring board tops, on above-mentioned wiring board, all is fixed with led chip; Make and enlarged the field of illumination; The illumination of formation non-blind area, and can improve service life, cut down the consumption of energy; Can be used in the various LED light fixtures alternative 15～45W incandescent lamp.

The beneficial effect of the utility model LED illuminating module is:

1. price is low, that light efficiency is high small-power paster LED is formed the tungsten filament stem stem of high-power illuminating module replace incandescent and need not large-area heat radiator.

2. do illuminating module with the PCB wiring board and the low-power LED chip that is welded, have be welded conveniently, firm advantage, cleverly three wiring boards are fused with decussate texture, be convenient to be welded and dispel the heat, increase service life and reduce light decay.

3.LED tandem compound, and interior dress resistance-capacitance depressurization and rectification circuit use surface mount elements, have the distinguishing feature that cost is low, the operating current variation is little, easy to assembly.

4. the existing equipment of incandescent and technology are accomplished whole lamp and are made, the upgrading and automated production in enormous quantities of favourable incandescent lamp bulb manufacturing enterprise.

Description of drawings

Fig. 2 is the fractionation structural representation of the utility model.

The specific embodiment

The specific embodiment of the utility model is following:

Embodiment: a kind of LED illuminating module; Like Fig. 1, shown in Figure 2; Comprise glass stem 1 and two wiring boards 2, in the middle of described two wiring boards, wherein a wiring board first half central authorities are provided with the breach 3 that vertically is provided with together; Another piece wiring board Lower Half central authorities correspondence is provided with 3, two wiring boards 2 of breach of vertically being provided with together breach 3 through correspondence and is that cross is plugged on together and welding is fixing; In glass stem 1, draw lead 4; Lead 4 is with wherein wiring board 2 a lower ends welding is fixing; Be fixed with a cross wiring board 5 at the top of two wiring boards 2; Two wiring board 2 residing planes are all vertical with cross wiring board 5 residing planes, on the wiring board of two right-angled intersections 2 and cross wiring board 5, all are welded with a plurality of led chips 6.

The contrast of the utility model and ordinary incandescent lamp is following:

1, compare with traditional incandescent lamp: power consumption decline 80%-90%; Light efficiency increases 7-8 doubly, surpasses electricity-saving lamp country efficiency primary standard; Luminous flux surpasses 30W incandescent lamp level: the life-span improves more than 50 times.

2, structure is firm, easy to assembly, and is low to the operating voltage requirement of LED, and cost lower (comparing with band constant-flow driver circuit) can directly be replaced incandescent lamp.

3, compare not mercurously with electricity-saving lamp, can reach the ROHS of European Union standard fully, be the green illumination of compliance with environmental protection requirements.

4, power is big, can reach 3-5W, and luminous flux 300lm reaches the brightness of 30W incandescent lamp, has practicality.

5, efficient energy-saving: each household calculates by 100,000,000 families, the whole nation with the general bubble of a 4W LED lamp: compare with incandescent lamp, but per hour power saving 2.9 ten thousand is spent; But compare also power saving 50% with electricity-saving lamp.
