Abstract

The utility model discloses a novel light-emitting diode (LED) tube light. The novel light-emitting diode (LED) tube light comprises a rear cover, an aluminum substrate, a surface mount device LED (SMD LED), a surface cover, a polycarbonate (PC) diffusion plate, a power supply and a cover plate, the SMD LED is arranged on the aluminum substrate, the surface cover is fixed at the lower end of the rear cover, the PC diffusion plate is disposed between the SMD LED and the surface cover, upper accommodating space and lower accommodating space which are separated are mounted in the rear cover, the aluminum substrate and the SMD LED are fixed in the lower accommodating space of the rear cover, the power supply is mounted in the upper accommodating space of the rear cover, the cover plate is fixed at the upper end of the power supply, and thereby the power supply is covered in the upper accommodating space of the rear cover. According to the novel light-emitting diode (LED) tube light, traditional high power LEDs with power of 1W are replaced by the SMD LED, the SMD LED has a small power and low luminous decay, and thereby the service life is long; and the power supply and the SMD LED are separately arranged, heat generated by the power supply and the SMD LED respectively can be timely dissipated through the rear cover, accordingly the heat dissipation is facilitated, and the service life of the entire light can be further prolonged.

Description

The New LED Down lamp

Technical field

The utility model relates to a kind of lighting device, particularly a kind of LED Down lamp.

Background technology

In the known technology, mostly the LED Down lamp is big high-powered LED lamp if adopting, and this high-powered LED lamp light decay is very big, thereby service life is short; In addition, the LED Tubular lamp external cover is provided with an accommodation space, and power supply and LED lamp all place in this same accommodation space, thereby the thermogravimetric that the heat of power supply and LED lamp are produced lumps together, and is unfavorable for heat radiation, so, also can make shorten the service life of whole light fixture.

The utility model content

The purpose of the utility model is to overcome the deficiency of present technology, and a kind of New LED Down lamp is provided, and it adopts SMD LED, and SMD LED and power supply branch be arranged, and so not only be beneficial to heat radiation, and SMD LED light decay is little, thus the long service life of whole light fixture.

For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:

A kind of New LED Down lamp; Comprise a bonnet, an aluminium base, be arranged at SMD LED on the aluminium base, be fixed in the bonnet lower end cover, be arranged at the PC diffuser plate between SMD LED and the cover; Also comprise a power supply and cover plate; Said bonnet set inside has last accommodation space and the following accommodation space that separates, and said aluminium base and SMD LED are fixed in the following accommodation space of bonnet, and said power supply places in the last accommodation space of bonnet; Said cover plate is fixed in power supply upper end, thereby power supply is placed on the bonnet in the accommodation space.

Said bonnet set inside has dividing plate, and said dividing plate is separated into said accommodation space and the following accommodation space gone up with bonnet inside.

Said aluminium base is fixed in the dividing plate lower surface.

Said bonnet lower surface is trapezoidal; Comprise first order step and second level step; The end face of said first order step is the face bottom of bonnet; The end face of second level step is lower than first order step, and said diffuser plate is arranged at second level step, and said cover contacts with bonnet first order step and fixes with bonnet.

Also comprise two inserted sheets, two ear springs, said bonnet dual-side is provided with holddown groove, and said inserted sheet inserts in the holddown groove and with bonnet and fixes, and said ear spring upper end is connected with inserted sheet.

The beneficial effect of the utility model is: adopt SMD LED to replace the LED of traditional high-power 1W power, SMD LED power is little, and light decay is low, thus longer service life; Power supply and SMD LED branch are arranged, and the heat that produces separately can both in time shed through bonnet, so, are more conducive to heat radiation, thereby can make further that the service life of whole light fixture is elongated.

The specific embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Like Fig. 1,2, shown in 3; The utility model LED Down lamp comprises a bonnet 1, an aluminium base 2, be arranged at SMD LED3 on the aluminium base 2, be fixed in bonnet 1 lower end cover 4, be arranged at the PC diffuser plate 5 between SMD LED3 and the cover 4; Also comprise a power supply 6 and cover plate 7; Said bonnet 1 set inside has last accommodation space 11 and the following accommodation space 12 that separates, and said aluminium base 2 and SMD LED3 are fixed in the following accommodation space 12 of bonnet 1, and said power supply 6 places in the last accommodation space 11 of bonnet 1; Said cover plate 7 is fixed in power supply 6 upper ends, thereby power supply 6 is placed on the bonnet 1 in the accommodation space 11.

In the present embodiment, said bonnet 1 set inside has dividing plate 13, and said dividing plate 13 is separated into above-mentioned accommodation space 11 and the following accommodation space 12 gone up with bonnet 1 inside.Said aluminium base 2 is fixed in dividing plate 13 lower surfaces.

As shown in Figure 2, in the present embodiment, preferably; Said bonnet 1 lower surface is trapezoidal, comprises first order step and second level step, and the end face of said first order step is the face bottom of bonnet 1; The end face of second level step is lower than first order step, and said diffuser plate 5 is arranged at second level step, and said cover 4 contacts with bonnet 1 first order step and be fixing with bonnet 1; So, being about to diffuser plate 5 fixes.

The utility model LED Down lamp adopts SMD LED3 to replace the LED of traditional high-power 1W power, and SMD LED3 power is little, and light decay is low, thus longer service life; In addition, power supply 6 is arranged with SMD LED3 branch, and the heat that produces separately can both in time shed through bonnet 1, so, is more conducive to heat radiation, thereby can makes further that the service life of whole light fixture is elongated.

In the present embodiment, the utility model LED Down lamp also comprises two inserted sheets 8, two ear springs 9; Said bonnet 1 dual-side is provided with holddown groove 14, and said inserted sheet 8 inserts in the holddown groove 14, and fixing with bonnet 1 through screw 10, and said ear spring 9 upper ends are connected with inserted sheet 8, specifically, is that the coil component spring (figure does not show) of ear spring 9 upper ends is connected with inserted sheet 8.

In the present embodiment, said bonnet 1 adopts aluminum alloy materials die casting to form, and is convenient to heat radiation like this, and can be outside bonnet 1 various colors in the list processing; Said PC diffuser plate 5 can be so that the light that SMD LED3 sends reaches free from glare, light transmittance is high, lighting angle is big, the even soft purpose of light.
