A plurality of the LEDs are welded to the front of the aluminum substrate; the back of the aluminum substrate is welded with an integrated circuit; the back of the aluminum substrate is coated with heat conduction silica gel and is adhered to the heat radiation substrate through filling of the heat conduction silica gel; the transmitting shield is provided with inward extending clamping heads which are embedded in clamping grooves at two ends of the heat radiation substrate; the heat radiation substrate has a semicircular section and a hollow cavity inside; the outer surface of the heat radiation substrate is provided with fins arranged like a comb; the transmitting shield has a semicircular section; and the inner surface of the transmitting shield is provided with a plurality of stripes which are distributed in a concave-convex manner and parallel to the axial direction of the transmitting cover. The surface mount type LED fluorescent lamp has a good head radiation effect and light weight, realizes uniform luminance, and is easy to assemble.

Description

A kind of adopting surface mounted LED fluorescent lamp

Technical field

The utility model relates to lighting field, relates in particular to a kind of adopting surface mounted LED fluorescent lamp.

Background technology

LED daylight light fixture has long, advantage such as luminous efficiency is high, radiation is low of life-span, has been widely applied to commerce, office and household every field now.But because single led lamp body is long-pending little, illuminance is lower, need a plurality of LED lamp set be installed on the light source substrate, uses same power supply centrally connected power supply.

Existing LED fluorescent lamp, its light source substrate mostly slide into cooling base or adopt screw to be fixed on the cooling base through the draw-in groove on the cooling base, make cooling base fully to contact with light source substrate, influence radiating effect; And existing LED fluorescent lamp has adopted most LED lamps to be certain rule and has been welded on the light source substrate; And outside the LED lamp, be covered with common transparent lamp shade; Can't solve the luminous uniformity and better heat dissipation problem of fluorescent lamp, and traditional cooling base employing solid construction, its weight is big; Radiating effect is unsatisfactory, thereby influences applying of LED fluorescent lamp.

Summary of the invention

In order to address the above problem, the utility model provides a kind of good heat dissipation effect, and luminous even, body weight is light, adopting surface mounted LED fluorescent lamp easy to assembly.

The technical scheme of the utility model is: a kind of adopting surface mounted LED fluorescent lamp; Comprise cooling base, aluminium base, a plurality of paster LEDs and diffuser, described plurality of LED is welded in the aluminium base front; The back side of aluminium base is welded with integrated circuit; The back side coated with thermally conductive silica gel of aluminium base and fill through this heat conductive silica gel is adhered on the cooling base, prolongs dop in said diffuser is provided with, in to prolong the draw-in groove at dop and cooling base two ends chimeric.

Further, said cooling base is that cross section is semicircular cooling base, and inside is provided with cavity, and the cooling base outer surface is provided with the fin that is pectination.Said cooling base set inside has cavity, has alleviated the weight of daylight lamp body, and its appearance is provided with the fin that is pectination, has further strengthened radiating effect.

Further, said diffuser is that cross section is semicircular diffuser, and the diffuser inner surface is provided with striped, and said striped is recessed into the diffuser inner surface or protrudes from the diffuser inner surface, and said striped is parallel with the axis direction of diffuser.Described diffuser inner surface is provided with striped, helps the even diffusion of light, has strengthened the luminous uniformity of fluorescent lamp.

The beneficial effect of the utility model is: the back side coated with thermally conductive silica gel of aluminium base and fill through this heat conductive silica gel is adhered on the cooling base; Make aluminium base contact very closely with cooling base; The heat that the paster LED lamp produces can be transmitted on the cooling base good heat dissipation effect rapidly; And the cooling base set inside has cavity, and its outer surface is provided with the fin that is pectination, has further strengthened radiating effect; The draw-in groove that prolongs dop and cooling base two ends in diffuser is provided with is entrenched togather, and assembly and disassembly are all very convenient; Described diffuser inner surface is provided with striped, helps the even diffusion of light, has strengthened the luminous uniformity of fluorescent lamp.

Fig. 2 is the structural representation of the utility model adopting surface mounted LED fluorescent lamp cross section.

The specific embodiment

Combine the accompanying drawing and the specific embodiment that the utility model is further specified at present.

With reference to figure 1, shown in 2; A kind of adopting surface mounted LED fluorescent lamp of the utility model comprises that cross section is semicircle cooling base 1, aluminium base 2, a plurality of paster LEDs 3 and diffuser 4; Described cross section is that its inside of semicircle cooling base is provided with cavity; Thereby alleviated the weight of daylight lamp body greatly, its outer surface is provided with the fin 12 that is pectination, has further strengthened the radiating effect of fluorescent lamp; Described plurality of LED 3 is welded in aluminium base 2 fronts; The back side of aluminium base 2 is welded with the integrated circuit (not shown); The back side coated with thermally conductive silica gel (not shown) of aluminium base 2, and fill through this heat conductive silica gel and to be adhered on the cooling base 1, make aluminium base 2 contact very closely with cooling base 1; The heat that paster LED lamp 3 produces can be transmitted to rapidly on the cooling base 1, has strengthened radiating effect; Said diffuser 4 is semicircular diffuser 4 for cross section, prolongs dop 41 in diffuser 4 is provided with, and it is chimeric with the draw-in groove at cooling base two ends to prolong dop 41 in this, makes that whole daylight lamp body project organization is simple, and assembly and disassembly are all very convenient; Diffuser 4 inner surfaces are provided with striped 42; Said striped 42 is recessed into the diffuser inner surfaces or protrudes from the diffuser inner surface; Said striped 42 is parallel with the axis direction of diffuser 4, this striped 42 be provided with the even diffusion that is beneficial to paster LED light, strengthened the luminous uniformity of fluorescent lamp.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
