An upright lamp having length adjustable lamp-post includes a lamp-post, a plug mounted on the lamp-post, and a fastener configured for connecting the lamp-post and the plug. The lamp-post has a jack opened therein. The plug is inserted into the jack. The plug has a uniform cross section area and cross section shape with that of the jack. A hole is opened in the plug along axial direction thereof and is configured for receiving the fastener. The hole is intersected with a side wall of the plug. When the fastener is threaded into the volume formed by the plug and the lamp-post, the interference fit joint between the fastener and the volume is realized as the volume is less than that of the fastener. And then, the mounting base module and the fastener are assembled onto the lamp-post.

An undervoltage protection circuit for LED lamp includes a DC/DC converter, and a controlling circuit module. The controlling circuit module includes a signal collecting unit configured for collecting a signal, a signal comparing unit electrically connected to the signal collecting unit, and a signal processing unit electrically connected to the signal comparing unit. The signal comparing unit is configured for comparing a signal input from the signal collecting unit with a threshold voltage. The signal processing unit is configured for processing the signal output of the signal collecting unit to turn on or turn off the DC/DC converter. Whenever the voltage input is less than the threshold voltage which indicates an undervoltage condition, the controlling circuit module produces a high level and causes the DC/DC converter to not work as a result. Inversely, the controlling circuit module drops to a low level and the DC/DC converter begins to work.

Undervoltage protection circuit for LED lamp

A lens includes an optical axis, a light source recess arranged through the optical axis, a reflection surface crossing through the optical axis, and a critical reflection surface which is arranged in a spaced relationship with the optical axis. The critical reflection surface is arranged between the light source recess and the reflection surface and receives the light from the light source recess and the reflection surface and reflects the light from the light source recess and the reflection surface towards the reflection surface. The emission light of the lens is light emitted forward of the light emitting surface which is reflected via the reflection surface and the critical reflection surface. Therefore, people cannot receive directly light emitted forward of the LED after it cross through the lens. In result, high luminance light from the LED is prevented from ripping into eyes, which achieve the aim of anti-glare.

Lens and LED module having the same

A lens, LED module and an illumination system includes an illuminated area; and at least an LED module for illuminating the illuminated area. The LED module includes an LED, and a lens mounted in the light path of the LED. The lens includes an optical axis, a light source recess arranged through the optical axis, a light emitting surface crossing through the optical axis, and a critical reflection surface arranged between the light source recess and the light emitting surface, wherein the light source recess is a rectangular hole in a section view which is vertical to the optical axis and has a center axis which overlaps with the optical axis, the light source recess has a wedge-shaped hole in a section view along the optical axis, the wedge-shaped hole has a top wall which crosses through the optical axis, the top wall has a convex surface.

Lens, LED module and illumination system having same

An illumination system includes at least an LED module, and at least an illuminated area. The LED module includes an LED, and a lens mounted in light path of the LED. The lens includes a light source recess, a first light emitting surface, a critical reflecting surface, and a second light emitting surface intersecting with the first light emitting surface and being on same side with the first light emitting surface. The first light emitting surface can receive more light quantity than the second light emitting surface. Although the light emitted from the first light emitting surface may have greater attenuation than the light emitted from the second light emitting surface, light emitted from the first light emitting surface can make up the intensity losses of attenuation as the first light emitting surface receives more light quantity than the second light emitting surface. As a result, the illumination systemhave uniform illumination pattern.
