Abstract: Disclosed is a LED lamp compatible with electronic ballast. The positive and negative electrodes of LED array are connected with two pins of lamp via four diodes respectively, by this way, regardless of which pin is connected to the positive electrode, the lamp circuit can form a conductive path to power for the LED array, and consumers can install the lamp without distinguishing the positive and negative electrodes, improving the efficiency of LED lamp replacement.

Abstract: A Light Emitting Diode (LED) fluorescent cover comprises the following components by weight: 90-96% of single-component solid silicone rubber, 3-8% of fluorescent powder and 1-2% of vulcanizer; and the preparation method includes the following steps: step 1): using mixed compound of the single-component solid silicone rubber, as well as the fluorescent powder and the vulcanizer as raw material to mix, standing for 2-4 h after mixing with open mill or internal mixer; step 2): controlling temperature, pressure and vulcanization time of vulcanizing machine according to size of the fluorescent cover mold, using the vulcanizing machine to carry out first vulcanization to the raw material that is obtained from the step 1) and placed in the fluorescent cover mold; step 3): with combined action of blower gun, taking the fluorescent cover out slowly; step 4): baking the semi-finished product in a closed space at a temperature of 150-200° C. for 1-2 h.

Abstract: An LED candle lamp for Christmas decoration, that includes: a lamp holder in a barrel shape provided with a mounting hole; a lamp body in a column shape, with one end mounted in the mounting hole, and the other end extending out of the mounting hole; a flexible LED lamp strip mounted on the end of the lamp body extending out of the mounting hole; a waterproof cover provided with a first cavity, in which the flexible LED lamp strip is located, and an opening of which is hermetically connected with the lamp body; a light-transmittable cover provided with a second cavity, in which the waterproof cover is located, and an entrance of which is hermetically connected with the inside wall of the mounting hole; the gaps at the connections of the light-transmittable cover, the lamp body, the waterproof cover, and the lamp holder are filled with sealant.

Abstract: A high color rendering LED, comprising a holder and two holder pins, wherein the holder is provided with a cup room, a blue LED chip and a red LED chip are mount in the cup room and connected in series, the serially connected blue LED chip and red LED chip are further connected to the holder pins, and in the cup room the blue LED chip and red LED chip are covered by the fluorescent gel. The present invention adds the dark red in its spectrum, whereby its R9 test index is effectively improved.

Abstract: The present invention discloses a surface-mount LED with optical lens, comprising a surface-mount LED with a flat plane on the top thereof and an optical lens packaged on said flat plane. The present invention decreases the light emitting angle and increase the luminosity of the LED through the light convergence effect by the optical lens; the present invention also can effectively enhance the usage of the side light rays through the light reflection effect of the cylinder, no extra reflection cup is required; under the condition of the same luminance being provided, less LEDs are used according to the present invention, thereby saving energy and reducing cost.
