Description

Lamp for surface cleaning device Cross Reference to Related Applications The present application claims priority from U.S. patent application Ser. No.18/826,900, entitled "Lamp for surface cleaning apparatus," filed on 6,9, 2024, which is incorporated herein by reference in its entirety. Technical Field The present disclosure relates generally to surface cleaning devices, and more particularly to a lamp for a surface cleaning device. Background The surface cleaning apparatus is configured to clean surfaces such as floors and other surfaces. The surface cleaning device may be, for example, a vacuum cleaner (dry, wet or wet/dry), an electric sweeper, a flat mop, or other type of surface cleaning device. Some surface cleaning devices include agitators in the form of cleaning pads, brushrolls, bristles, and the like, which are configured to agitate the surface being cleaned in order to more effectively remove debris, such as dirt, food fragments, and other debris, from the surface. Some surface cleaning apparatuses that include agitators also include a light source configured to illuminate the surface being cleaned to assist in displaying debris on the surface for cleaning, which may assist a user in controlling the surface cleaning apparatus to better clean the surface by moving the agitators over the debris. However, the light emitted by the surface cleaning apparatus may not be effective, as, for example, the surface cleaning apparatus may be used to clean a variety of different types of surfaces having different colors. On some surface debris and on surfaces having different colors, the lamp may not illuminate the dirt. Disclosure of Invention Generally, a lamp for a surface cleaning apparatus and a method of using a lamp for a surface cleaning apparatus are provided. In one aspect, a surface cleaning apparatus is provided that in one embodiment includes a cleaning head, a lens, and a lamp. The cleaning head is configured to move over a surface to be cleaned. The lens is located at the cleaning head. A lamp is located at the cleaning head and is configured to emit blue light through the lens to illuminate the surface to be cleaned and to illuminate debris on the surface. The surface cleaning apparatus may be varied in any number of ways. For example, the blue light may have a wavelength in the range of 400nm to 494 nm. Furthermore, the maximum current of the lamp may be, for example, 350mA or 700mA. For another example, the blue light may have a wavelength in the range of 455nm to 485 nm. For another example, the surface cleaning apparatus may further include an agitator at the cleaning head, and the agitator may be configured to rotate to agitate debris on the surface to be cleaned. Further, the cleaning head may be configured to move in a forward direction over a surface to be cleaned, the agitator may be located at a forward portion of the cleaning head, and the light and lens may be located laterally of the agitator and at the forward portion of the cleaning head, the surface cleaning apparatus may further comprise an actuator configured to be actuated by a user and thereby cause the light to begin emitting blue light and causing the agitator to begin rotating, the surface cleaning apparatus may further comprise a fluid reservoir configured to hold a cleaning fluid, and the surface cleaning apparatus may further comprise a fluid dispenser configured to apply the cleaning fluid to the agitator and/or the surface to be cleaned, and/or the surface cleaning apparatus may further comprise a motor configured to drive rotation of the agitator, and the surface cleaning apparatus may further comprise an electrical power supply configured to supply electrical power to the light and the motor. For another example, the blue light may be configured to illuminate an area on the surface to be cleaned, a first corner of the area may be located at the lens, a first edge of the area may extend from the first corner of the area to a second corner, the second corner may be located laterally outward of the cleaning head at a first side of the cleaning head, the first edge may be at a first angle in the range of 120 ° to 140 ° with the front surface of the cleaning head, a second edge of the area may extend from the first corner of the area to a third corner, the third corner may be located laterally outward of the cleaning head at a second side of the cleaning head opposite the first side of the cleaning head, the second edge may be at a second angle with the front surface of the cleaning head, and the second angle may be in the range of 1 ° to 25 °. Furthermore, the central axis of the region may be at an angle of 70 ° to the front surface of the cleaning head, and/or the region may have a substantially triangular shape. Further, the region may be located entirely in front of the agitator, i.e. at the cleaning head and configured to rotate to agitate debris on the surface to be cleaned. In addition, the lamp and lens may b
