Description

A kind of SMD light-focusing type straight cutting light-emitting diode pixel lamp

(1) technical field: the utility model relates to a kind of light-emitting diode pixel lamp that is used for outdoor display screen, is the light emitting diode (LED) display screen parts, belongs to the display device class.

(2) background technology: the existing light emitting diode that is used for outdoor display screen, adopt all employings direct insertion LED of light-focusing type light emitting diode, it is connected with printed board is following: see Fig. 4, body 1a is inserted in the printed board 5, pin one b plane component face 5.1 from the printed board passes, fixedly conducting of welding on the face of weld 5.2 in its lower section, all pin one b is arranged in the face of weld below.This structure, make numerous pins take the big quantity space in printed board below, so that can't put other components and parts, must set up a new printed board, and also need be communicated with former printed board, increase up to a hundred contact pins thus with inserting mode, because of there is loose contact in contact pin, cause fault many, material is many, and cost increases.The existing patch light-emitting diode that can weld on component side all is not the light-focusing type light emitting diode, and its front face brightness is more far short of what is expected than light-focusing type light emitting diode, can not satisfy the requirement of outdoor display screen to brightness.

(3) summary of the invention: a kind of SMD light-focusing type straight cutting light-emitting diode pixel lamp that the purpose of this utility model provides, the one, the existing light-focusing type direct insertion LED outdoor display screen printed board of solution is many, fault many and the high problem of cost, and the 2nd, guarantee the required brightness of outdoor display screen.

A kind of SMD light-focusing type straight cutting light-emitting diode pixel lamp includes the light-focusing type straight cutting light emitting diode 1 of body 1a and pin one b, it is characterized in that

A lamp socket 2 is set, has the upper and lower through hole that communicates on its body back up pad 2a, one group of light-focusing type straight cutting light emitting diode 1 vertically is loaded on respectively in each through hole that shape matches; Each pin one b is at lamp socket body back up pad lower inner cavity; 2) every light-focusing type straight cutting led pins height h of this group ₁Identical.

Above-mentioned through hole is one group of through hole that light-focusing type straight cutting light emitting diode 1 pin one b passes and matches, and becomes pin through hole 2bb; Pin through hole top is for supporting the body bayonet socket 2b that body 1a and shape match, and body bayonet socket below is body back up pad 2a.

Above-mentioned lamp socket 2 is a rectangle, and there is support column 6 bottom on four angles, and the height of support column is hc, and the thickness of body back up pad 2a is h2a, and the height hc of support column 6 is the thickness h 2a that pin height h1 deducts body back up pad 2a.Side leaves opening 2E before and after the lamp socket, can be convenient to keep in repair and check the welding quality between pin and first device face.

Above-mentioned one group of light-focusing type straight cutting light emitting diode 1 can be one or more than.Register pin 4 can be established in 2 times bottoms of above-mentioned lamp socket.But the space filling with sealant 3A that above-mentioned body body back up pad top and light emitting diode are 1.Can be provided with the LED core 1.3 in the recessed cup of the metal support 1.1, the metal on the support that link to each other with pin 1.2, the recessed cup and the oval transparent colloid 1.4 of their outsides in the above-mentioned light-focusing type straight cutting light emitting diode 1 body 1a.

The utility model beneficial effect: i. light-focusing type straight cutting light emitting diode is bigger than non-light-focusing type light emitting diode front face brightness, and lateral luminance increases with angle and reduces.And outdoor display screen at first will solve brightness, and it is necessary adopting light-focusing type, so this patent employing light-focusing type light emitting diode, has guaranteed the required brightness of outdoor display screen.Ii. each light-focusing type straight cutting led pins height h ₁Identical, and by the lamp socket support, it is SMD that direct insertion mounting means is changed into, and makes light-focusing type straight cutting light-emitting diodes can be welded on the pad of printed board component side simultaneously, solved the problem that existing direct insertion structure takies the big quantity space in face of weld below, made it that printed board is few, fault is few, cost is low.Iii. one or more light-focusing type straight cutting light emitting diodes adopt on lamp socket support and the body back up pad and use the fluid sealant sealing and fixing, help the fixing and display screen waterproof of pin, satisfy the outdoor display screen demand.Iv. pixel lamp inserts printed board with register pin, and convenient fixing is accurately located pin and pad.V. establish the body back up pad 2a and the body bayonet socket 2b that support body on each pin through hole, body and whole light emitting diode are very firm on lamp socket thus.Vi. side leaves opening before and after the lamp socket base, can be convenient to keep in repair and check the welding quality between pin and component side pad.

(5) embodiment: the following formation of the SMD light-focusing type straight cutting of present embodiment light-emitting diode pixel lamp:

See Fig. 1, Fig. 3 is provided with lamp socket 2, forms one group by three light-focusing type straight cutting light emitting diodes 1, adopts three couples of pin one b to be respectively charged in three couples of through hole 2bb that have on the lamp socket 2 body back up pad 2a; The three pairs of body bayonet socket 2b (see figure 3)s of through hole 2bb top for putting body 1a.Three couples of pin one b stretch the lower inner cavity at lamp socket body back up pad 2a.

See Fig. 1, Fig. 2, above-mentioned lamp socket 2 is a rectangle, and there is support column 6 bottom on four angles, and the height of support column is hc, and body back up pad 2a thickness is h2a, and the height of support column 6 is the thickness h 2a that pin height h1 deducts body back up pad 2a.Because the support of support column 6, make lamp socket before and after side leave opening 2E, can be convenient to keep in repair and check the welding quality between pin and first device face.

See Fig. 1, Fig. 2, body back up pad 2a top has peripheral annular groove, filling with sealant 3A in groove and between body; Perhaps single pixel lamp is not filled 3A, and after pixel lamp is assemblied in the printed board, carrying out integral-filled fluid sealant again.This organizes three light-focusing type straight cutting led pins height h ₁Identical, on the pad that is affixed on and is welded in component side 5.1, general three height h ₁Tolerance is controlled at less than 20 and gets final product.

See Fig. 1, see Fig. 2, three light-focusing type light emitting diodes are three kinds of colors of red, green, blue.Be provided with the LED core 1.3 in the recessed cup of the metal support 1.1, the metal on the support that link to each other with pin 1.2, the recessed cup and the oval transparent colloid 1.4 of their outsides in the light-focusing type body 1a.
