Abstract

The utility model provides a high transparency integrated-face light source module. The high transparency integrated-face light source module comprises a plurality of blue-ray light-emitting diode (LED) lamp beads, an aluminum substrate and lateral baffles, wherein the blue-ray LED lamp beads are surface mounted device (SMD) LEDs. The blue-ray LED lamp beads are welded on the aluminum substrate. The lateral baffles are installed on the aluminum substrate. A transparent faceplate is fixed on the lateral baffles. The high transparency integrated-face light source module utilizes the transparent faceplate and a lampshade is saved. Thus, air refraction between a light source and the lampshade is reduced. The lampshade is not needed on the premise that dust prevention and protection of LED chips are achieved. Therefore, about ten percent light transmission quantity is improved under the premise that power is not increased.

Description

The integrated area source module of a kind of high transmission rate

Technical field

The utility model relates to lighting technical field, particularly relates to the integrated area source module of a kind of high transmission rate.

Background technology

Along with the day by day exhaustion of the energy and the enhancing of environmental consciousness, the LED lighting engineering of more power saving, environmental protection has obtained paying close attention to widely, and the LED lighting engineering has obtained adopting widely on various illuminating equipments.

Along with the progress of LED technology and the reduction of cost, SMD(Surface Mounted Devices, surface mount device) and COB(Chip On Board, chip on board) the integration packaging technology has been widely used in the LED field of light fittings.But existing LED lighting engineering has a lot of places not fully up to expectations, and for example: the lamp pearl illumination of SMD paster is traditional luminous spot light mode of single-point, has the serious defective of dazzle.Settling mode of the prior art is to install opaque lampshade additional to make light soft, but lampshade can lose 25%-30% light efficiency.Emerging COB multiple spot encapsulation technology adopts small size blue-ray LED wafer is welded on aluminium base, then the overall perfusion fluorescent glue, and fluorescent glue is sent the light of white or other colors after blue-light excited, solved dazzling problem.But because undersized wafer power is low, luminous flux is low, therefore can only improve logical light quantity by increasing number of wafers.But the energy consumption of the LED lamp of this structure is very high, has run counter to the theory of LED energy-conserving and environment-protective.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of light transmittance that can improve to save the integrated area source module of high transmission rate of energy consumption.

For solving the problems of the technologies described above, the new embodiment of this practicality provides a kind of high transmission rate integrated area source module, comprise a plurality of blue LED lamp pearls 1, aluminium base 4, side shield 2, wherein said blue LED lamp pearl 1 is the SMD paster LED, and described blue LED lamp pearl 1 is welded on described aluminum base circuit board 2; Described this aluminium base 4 is provided with side shield 2, is fixed with transparent panel 3 on described side shield 2.

Preferred as technique scheme, described aluminium base 4 upper surfaces are provided with encapsulated layer 6.

Preferred as technique scheme, the surrounding of described aluminium base 4 also is provided with box dam side plate 5.

Preferred as technique scheme, described encapsulated layer 6 is made for the silica gel or the epoxy resin that have mixed fluorescent material.

Preferred as technique scheme, described blue LED lamp pearl 1 is SMD3014 or SMD3020 or SMD3528 or SMD5050 or SMD5630.

The beneficial effect of technique scheme of the present utility model is as follows:

Adopt transparent panel in above-mentioned scheme and saved lampshade; thereby reduced the air refraction between light source and lampshade; no longer need lampshade under the prerequisite that realizes dustproof and protection LED chip, thereby improve the logical light quantity of 10% left and right under the prerequisite of hoisting power not.

The specific embodiment

For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.

The utility model embodiment has proposed a kind of high transmission rate LED fluorescent tube, its structure as shown in Figure 1 and Figure 2, comprise a plurality of blue LED lamp pearls 1, aluminium base 4, side shield 2, wherein said blue LED lamp pearl 1 is the SMD paster LED, and described blue LED lamp pearl 1 is welded on described aluminum base circuit board 2; Described this aluminium base 4 is provided with side shield 2, is fixed with transparent panel 3 on described side shield 2.Adopt transparent panel in above-mentioned scheme and saved lampshade; thereby reduced the air refraction between light source and lampshade; no longer need lampshade under the prerequisite that realizes dustproof and protection LED chip, thereby improve the logical light quantity of 10% left and right under the prerequisite of hoisting power not.Wherein, described blue LED lamp pearl 1 is SMD3014 or SMD3020 or SMD3528 or SMD5050 or SMD5630.

As shown in Figure 1, described aluminium base 4 upper surfaces are provided with encapsulated layer 6, and this encapsulated layer 6 is made for the silica gel or the epoxy resin that have mixed fluorescent material.

By the blue LED lamp pearl that had encapsulated is arranged an encapsulated layer again, well solved the deficiency that traditional SMD and COB fluorescent tube produce hot spot and dazzle, can directly use Transparent lamp shade or not use lampshade, having removed from and used frosted lampshade or the white lampshade of milk to stop 30% light loss that hot spot and dazzle bring.The utility model adopts the overlarge area radiator structure simultaneously, and encapsulated layer and the direct heat loss through conduction of air that the materials such as employing silica gel are made lower the lamp body temperature, increase the service life.

Wherein, this encapsulated layer 6 is made for the silica gel or the epoxy resin that have mixed fluorescent material, to strengthen fixed effect and can not be in the light.Can avoid simultaneously producing from a plurality of media the light loss of refraction and reflection, light transmittance is high, effectively improves light emission rate 10%-20%.

Wherein, the surrounding of described aluminium base 4 also is provided with box dam side plate 5, and this encapsulated layer 6 can be arranged on aluminium base 4 with the blue LED lamp pearl 1 on encapsulation aluminium base 4.And this encapsulated layer 6 is spacing to prevent mobile being damaged by box dam side plate 5.

The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
