Abstract

An integrated lamp is provided, including: a shell member, defining a mounting space; a light-evening member, disposed within the mounting space, including an incident portion and a light-penetrable region; a first LED unit, disposed within the mounting space, at least part of light from the first LED unit being incident into the incident portion and diffused within the light-penetrable region to become a surface light source; a second LED unit, disposed within the mounting space, overlapping with the light-penetrable region, configured to light to form at least one point light source; wherein the light form the first LED unit and the light form the second LED unit emit out from the light-penetrable region, at the same time or respectively.

Claims

1. An integrated lamp, including:

a shell member, defining a mounting space;

a light-evening member, disposed within the mounting space, including an incident portion and a light-penetrable region;

a first LED unit, disposed within the mounting space, at least part of light from the first LED unit being incident into the incident portion and diffused within the light-penetrable region;

a second LED unit, disposed within the mounting space, overlapping with the light-penetrable region;

wherein the light form the first LED unit and the light form the second LED unit emit out from the light-penetrable region, at the same time or respectively;

a light-shielding unit;

wherein the first LED unit is disposed on a first printed circuit board, the second LED unit is disposed on a second printed circuit board, as viewed in a first direction, the light-evening member, the first printed circuit board and the second printed circuit board are arranged to overlap with one another in order, and the first printed circuit board includes a plurality of through holes arranged along the first direction and corresponding to the second LED unit;

wherein as viewed in the first direction, the light-shielding unit covers the first LED unit, the light from the first LED unit emits out in a second direction, the second direction passes through the incident portion so that the light from the first LED unit comes into the light-penetrable region, and the second direction is transverse to the first direction;

wherein the first LED unit has an emitting face facing toward a direction transverse to a direction toward which an emitting face of the second LED unit faces;

the first and second printed circuit boards abut in surface contact in the first direction, and the second LED unit is located within the through holes;

a light-guiding structure which is honeycomb-shaped is disposed on the light-penetrable region;

the integrated lamp further includes a light-diffusing cover, the light-diffusing cover is disposed on the shell member and covers the light-penetrable region;

the luminance of the second LED unit is greater than that of the first LED unit;

the light-evening member is flexible and transparent;

the light-evening member further includes a main body and a sheet member, the main body is greater than the sheet member in thickness, the sheet member is connected with and extends laterally from a first end surface of the main body, the sheet member and a second end surface of the main body are in a stepped configuration, the light-penetrable region is disposed on the main body, an annular lateral side of the main body servers as the incident portion, the first LED unit is disposed opposite to the annular lateral side of the main body;

the second end surface of the main body is closer to the first printed circuit board than the first end surface of the main body;

the sheet member is clamped between the light-shielding unit and the first LED unit;

a cross-section of the light-evening member taken along the first direction is of a thin wide T-shape;

the first LED unit includes a plurality of first LEDs, the second LED unit includes a plurality of second LEDs, a number of the plurality of through holes is equal to that of the plurality of second LEDs, the plurality of first LEDs are disposed on a periphery of the first printed circuit board, the plurality of through holes and the plurality of second LEDs are located at a middle of the first printed circuit board, the plurality of second LEDs are equidistantly arranged;

a number of the plurality of first LEDs is greater than that of the plurality of second LEDs.

2. The integrated lamp of claim 1, wherein a convex lens unit covers the through holes, and a part of the light from the second LED unit goes through the convex lens unit.
