Specific embodiment

In order to more clearly state the utility model, the utility model is further described with reference to the accompanying drawing.

The vehicle-mounted reading lamp uniformly spread by diffuser plate referring to Fig. 1, a kind of lamp bead side wall shines, including bottom case 1, Pcb board 2, diffuser plate 4 and transparent face mask 5；Bottom case 1 and translucent cover are mutually clamped to form accommodating space, and pcb board 2 and diffuser plate 4 are put It sets in accommodating space；Pcb board 2 is equipped with the lamp bead 3 outstanding to outside pcb board 2, lamp bead 3 and 2 opposite face of pcb board as the top of lamp bead 3 Face is 3 side of lamp bead between 3 top surface of lamp bead and pcb board 2；Diffuser plate 4 is equipped with through-hole 41, and lamp bead 3 is connected in through-hole 41, and 3 side wall of lamp bead is corresponding with 41 side wall of through-hole；Lamp bead 3 shines after the injection of 3 side wall of lamp bead, by diffuser plate 4, finally from saturating Bright mask 5 projects.

Theoretical basis: when light is mapped to the smooth interface of another medium from a kind of medium, a part of light is reflected by interface, Another part light reflects in another medium through interface；The incidence angle of light is equal to angle of reflection, and reflected light and incident light exist The two sides of normal in same plane, here it is reflection laws.And refracted light then meets the law of refraction: refracted light is located at incidence In the plane of light and normal, light and incident light are reflected in normal two sides, and the ratio between the sine at incidence angle and refraction angle is a constant. The law of refraction and reflection law are all the bases of geometric optics, they are also not only the development of optical technology in theoretical research Design with optical articles is laid a good foundation；The maximum feature of diffuser plate 4 is that very big interference is caused to light, regardless of original sets The distribution curve flux of meter is how much to spend, as long as light is through diffuser plate 4, it can make beam angle become 160 ~ 176 degree；

In the present embodiment, after the interference that whole light that 3 side of lamp bead issues pass through diffuser plate 4, from diffuser plate 4 It projects top surface；It is projected again by transparent face mask 5, in the exactly uniform area source that shines that outside is seen；It is common, LED It is that forward direction shines, the direct transparent face mask 5 of light, outside sees that two LED shine, and is not that a face shines；If conventional lamp is such as Fruit wants surface source luminescence, with many lamp beads 3 or uses COB light source；Cost is just very high in this way；And this reading lamp is to lamp bead 3 quantity does not require, and in the present embodiment, selects two lamp beads 3, the quantity of through-hole 41 is equal with 3 quantity of lamp bead；And through-hole 41 Depth be more than or equal to lamp bead 3 top surface to pcb board 2 distance；Specifically luminous lamp bead 3 is rectangular, there are four side, Lamp bead light shines from 360 degree of four sides.

Referring to Fig. 2, bottom case 1 is the high spill of intermediate low surrounding, spill outer wall is equipped with lug boss, and transparent face mask 5 is equipped with Epitaxy part 52, epitaxy part 52 are equipped with through-hole 41, and lug boss is caught in card hole 53, so that bottom case 1 and translucent cover are mutually clamped to be formed Accommodating space；Preferably, face of the convex block 13 far from 1 outer wall of bottom case is inclined-plane, and inclined-plane is from close concave-shaped openings end to far from recessed The inclination of shape open end；In snap-fitting process, epitaxy part 52 is slided along 41 inclined-plane of through-hole, until convex block 13 is caught in card hole 53, It is easy for installation；Wherein, 1 outer wall of bottom case is additionally provided with flank section 11 described in two flanks and is additionally provided with mounting hole 12；Bolt passes through mounting hole 12 is fixed in the car by bottom case 1.

In the present embodiment, 5 surface of transparent face mask includes transmittance section 51, and transmittance section 51 and diffuser plate 4 are bonded to each other and just Diffuser plate 4 is covered well；The light of diffuser plate 4 is all projected from transmittance section 51；The luminous brightness of lamp is abundant.

In the present embodiment, bottom case 1 and translucent cover are mutually clamped to form accommodating space after, bottom case 1, pcb board 2, diffuser plate 4 Successively it is close to transparent face mask 5；1 bottom of bottom case is the height of reading lamp at a distance from 5 top of transparent face mask；Lamps and lanterns thickness is more It is thin.

The advantage of the utility model is:

Disclosed above is only several specific embodiments of the utility model, but the utility model is not limited to this, The changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
