Patent number: 9970642Abstract: An anti-explosion LED lamp housing is used to separate an illumination module from an external environment and comprises a housing body and a housing cover. The housing body includes a shell having a spherical segment-like shape, an accommodation basin connected with the concave portion of the shell, and a wiring hole penetrating the housing body and the accommodation basin. The accommodation basin includes a first platform encircling the wiring hole and receiving the illumination module; a second platform encircling the first platform and having a level difference to the first platform; and an annular wall encircling the second platform. The housing cover includes a light-permeable plate disposed on the second platform; an annular pressing element forcing the light-permeable plate to press against the second platform and engaged with the annular wall tightly. The diameter of the circular base face of the shell is 4-15 times the height of the shell.Type: GrantFiled: September 7, 2016Date of Patent: May 15, 2018Assignee: LI-HONG SCIENCE & TECHNOLOGY CO., LTD.Inventors: Ming-Tien Chien, Ching-Yuan Juan, Han-Wen Chang, Mei-Hsiang Wu, Wei-Cheng Juan

Patent number: 9702536Abstract: An explosion-proof lamp cable gland is disposed in a channel of a coupling portion of an explosion-proof lamp for a cable to pass through, and includes a first explosion-proof member disposed at one end of the channel remote from an opening of the coupling portion and a compact member disposed at another end of the channel close to the opening of the coupling portion to connect to the first explosion-proof member. The explosion-proof lamp cable gland of the invention thus formed is simpler in structure and smaller in size, and can achieve explosion-proof effect as a conventional connector that is bulkier in size. Thus not only the cost is lower, but serial connection among the explosion-proof lamps also can be accomplished easily to make application versatile.Type: GrantFiled: April 25, 2014Date of Patent: July 11, 2017Assignee: LI-HONG SCIENCE & TECHNOLOGY CO., LTD.Inventors: Ming-Tien Chien, Ching-Yuan Juan, Han-Wen Chang, Cheng-Lung Juan
