The invention relates to a cold-hot combined assembly method of two metal castings, and an LED lamp for assembling a main body radiator as an A die casting piece and a heat dissipating module as a B die casting piece by adopting the method. The method comprises the following steps: the cylindrical A die casting piece with a draft angle of 0.8-5 degrees and a thermal expansion coefficient of 1 E-6 / DEG C is produced and cooled to the normal temperature; the B die casting piece with a circular hole is produced, and the mold stripping temperature is 150-400 DEG C; the thermal expansion coefficientgamma B of the B die casting piece is 1E-6 / DEG C; and within half a minute of mold stripping of the B die casting piece, an outer limiting piece of the A die casting piece is aligned to an inner limiting surface of the B die casting piece to place in the circular hole of the B die casting piece for cooling to the normal temperature. The method can save the energy and guarantee the precision and the surface smooth of produced devices.

A brightness sensing system includes an image pickup unit for taking an image of a target space and a calculation unit for calculating the brightness of an image pickup area based on the image taken by the image pickup unit. In the brightness sensing system, if the difference or the ratio between an image as a whole and a pixel block formed of one or more pixels is equal to or greater than a threshold in terms of brightness change between a previously-taken reference image and a currently-taken target image, the calculation unit excludes the pixel block from comparison candidates and compares the brightness of the target image with the brightness of the reference image based on the remaining pixels other than the pixel block.

The invention relates to an object inspection system for object abnormity inspection. The object inspection system comprises illumination equipment which is configured to irradiate an object to be inspected and camera equipment which is configured to carry out image shooting on the object to be inspected under the irradiation of the illumination equipment. The illumination device comprises a curved surface light cover and a plurality of monochromatic visible light sources, wherein the curved surface light cover has a concave curved surface which is arranged to face the object to be inspected;the plurality of monochromatic visible light sources are arranged on the concave curved surface of the curved surface light cover and are used for irradiating the object to be inspected; and the positions of the plurality of monochromatic visible light sources and the shape of the concave curved surface can make irradiation light formed by monochromatic visible light emitted by the plurality of monochromatic visible light sources in a predetermined illumination range irradiate the object to be inspected, and the illumination deviation of the irradiation light does not exceed 10%. The object inspection system can acquire a clear object image, and whether the object to be inspected is abnormal can be determined based on the object image.

The invention discloses a municipal illuminating LED street lamp comprising a vertical column, a lamp pole, a lamp body and a controller. The controller adjusts the position and the angle of the lamp body on the lamp pole based on the ultrasonic reflectivity. When the street lamp is shielded by branches and leaves of street trees, the position and illuminating parameters of the municipal illuminating LED street lamp can be adjusted automatically to guarantee the illuminance of a pavement, and when excessively shielded, the street lamp can automatically notify relevant departments to request pruning so that the tree shielding problem can be solved conveniently and effectively, the time of branch pruning of the municipal administration is reduced, and the manpower cost and the financial resource cost are reduced.

The invention discloses a municipal lighting LED street lamp. The municipal lighting LED street lamp comprises a stand column, a lamp post, a lamp body and a controller. The controller can adjust the position and angle of the lamp body on the lamp post based on images of branches and leaves. When the municipal lighting LED street lamp is shielded by border tree branches and leaves, the lighting lamp position and lighting parameters can be adjusted automatically so as to guarantee illuminance of the road surface. When shielding is too serious, relevant departments can be automatically informed to ask for trimming, the problem of tree shielding can be solved conveniently and effectively, the municipal branch trimming frequency is decreased and the expenditure of manpower and financial resources is reduced.

The invention discloses an LED lighting device. The lighting device includes a transparent box, a PCB arranged in the transparent box, and a plurality of LEDs arranged on the PCB in a laying manner. The LEDs are connected through circuits. The driving current adopted by the LEDs is in a range of 55% to 85% of a rated current of the LEDs. The installation density of the LEDs on the PCB is 1.0 to 1.5 per cm2. In the invention, the driving current of the LEDs is reduced. By increasing the number of the LEDs assembled on the lighting device, the integral luminance of the lighting device is kept. The heating volume generated on the lighting device is reduced. And the service lifetime of the LEDs used on the lighting device is prolonged. Besides, the economical efficiency of the LED lighting device used in indoor cultivation facility is also improved.
