An optical lens including a first light exit surface, a total internal reflection (TIR) surface, a second light exit surface and a third light exit surface connected in an order, and correspondingly has a first intersection, a second intersection and a third intersection therebetween. A first line between the first intersection and a reference point on an optical axis of the optical lens intersects with the optical axis to form a first angle between 30 degrees to 60 degrees, and a first direction of the reference point pointing toward a point on the TIR surface intersects with a normal of the first light exit surface at the point to form a reflecting angle larger than a critical angle of TIR. A second line between the second intersection and the reference point intersects with the first line to form a second angle between 10 degrees to 30 degrees.

Optical lens and light source device

An illumination device includes a light guiding core, an optical film and a light emitting module. The optical film separately surrounds the light guiding core. A ratio of a diameter of the optical film to a diameter of the light guiding core is between 2 and 3. The light emitting module is disposed at one side of the light guiding core.

Illumination device

An illumination module includes a light bar, an LED assembly, a positioning member, a sleeve and a lamp receptacle. The light bar has a first end and a second end opposite the first end. A microstructure layer or a reflective layer is formed on the light bar, and a positioning pillar is formed on an outer side of the light bar. The emitting light of the LED assembly is diffused by the microstructure layer or reflected by the reflective layer to spread over the entire light bar. The positioning member, the sleeve, the LED assembly or the lamp receptacle has at least one guide slot that engages with the positioning pillar of the light bar.

Illumination module and light bar used in the same

A lamp module is provided. The lamp module includes a main body and a plurality of light emitting diodes. The light emitting diodes are disposed on the main body. Each light emitting diode emits a light to a illuminated region and form a corresponding light region. The light regions formed on the illuminated region by the light emitted by adjacent light emitting diodes are at least partially overlapped.

Lamp module and desk lamp using the same

A backlight module includes a frame, a reflective sheet, a light guide plate, a light source, and an optical film set. The frame defines an accommodation space, and the reflective sheet is disposed in the accommodation space. The light guide plate is disposed in the accommodation space and on one surface of the reflective sheet. The optical film set is disposed one side of the light guide plate opposite the reflective sheet. The reflective sheet is hollowed out at a position overlapping the light source to form at least one opening so as to reduce light halos.
