The light emitting elements (31) are further configured to emit second light (42). The second light (42) is impinging on the interior surface (11) of the cavity (10). The optical module (20) is configured to collimate the first light (41) in a transverse plane. The transverse plane is perpendicular to the longitudinal axis (L) of the lighting device (1). The optical module (20) is further configured to produce collimated light so as to increase the degree of collimation of light, in the transverse plane, transmitted from the optical module (20) as compared to the first light (41) prior to transmission through the optical module. At least one of the interior surface (11) of the cavity (10), the plurality of light-emitting elements (31) and the optical module (20) is or are configured such that the second light (42), reflected by the interior surface (11) of the cavity (10) and subsequently having impinged upon the surface (21) of the optical module (20) and transmitted from the optical module (20), is light for which at least 3% of the total luminous flux is in the wavelength range 400-470 nm.

Abstract: A clamp lamp could clamp a screen having a front surface and a rear surface is provided. The clamp lamp includes a first clip, a second clip and a light-emitting module. When the clamp lamp clamps an edge of the screen, the first and second clips abut on the front surface and the rear surface of the screen respectively. The light-emitting module is connected to the first clip and includes a casing, a light-emitting element and a light-reflecting element. The casing has a light outlet. The light-emitting element is disposed in the casing and configured to emit a light and reflect the light to illuminate the front of the front surface through the light outlet. The light-reflecting element has first and second reflecting surfaces connected to each other. The first reflecting surface has several reflecting points, each having a radius of curvature equal to or greater than 25 mm.

Abstract: A solid state lighting (SSL) with a solid state emitter (SSE) having thermally conductive projections extending into an air channel, and methods of making and using such SSLs. The thermally conductive projections can be fins, posts, or other structures configured to transfer heat into a fluid medium, such as air. The projections can be electrical contacts between the SSE and a power source. The air channel can be oriented generally vertically such that air in the channel warmed by the SSE flows upward through the channel.

Abstract: A bundle beam UV LED ultraviolet light sweeping method includes: activating electrical power to input into a PCB to light up a bundle beam UV LED ultraviolet light bead and driving a motor to cause a polygonal multiple-reflective-surface aluminum mirror to rotate, ultraviolet light from the UV LED being projected toward the reflective surface, and reflected by the reflective surface to change light direction for successive back-and-forth home-position-returning sweeping, the light converting from lines into sectorial shapes that are connected to form a large ultraviolet light operation region. The device includes a rotating device having a motor of which a spindle is mounted with a polygonal multiple-reflective-surface aluminum mirror; an UV LED bundle beam light source assembly having a bundle beam UV LED ultraviolet light bead fixed on a PCB; and a fixing base having a main body and a plurality of mounting braces.

Abstract: A backlight module comprises a back plate, a reflective sheet arranged on the back plate and forming a plurality of openings, a plurality of light-emitting elements located in the plurality of openings, at least one optical element arranged on the reflective sheet, and at least a supporting element configured between the back plate and the reflective sheet. The supporting element can move along with the reflective sheet. The supporting element has a base portion and a supporting portion extending from the base portion towards the optical element. The base portion of the supporting element is located between the back plate and the reflective sheet. The supporting portion of the supporting element passes through the reflective sheet to support the optical element. The supporting element is not a fixed design and can move along with the reflective sheet. Therefore, other plates under the reflective sheet do not require openings, which can improve assembly convenience and effectively reduce the mechanism interference caused by the expansion and contraction of the reflective sheet. The invention also provides a display device including the backlight module.
