Description

LED lamp

Technical Field

The utility model relates to a LED technical field especially relates to a LED lamp.

Background

LED is by the more and more extensive application in outdoor places such as building and building facade, all has higher requirement to the shell protection of lamps and lanterns in outdoor professional illumination field, and waterproof dustproof is the indispensable protection item. Outdoor LED lamps have higher requirements on the protection level of the lamp shell, and generally the protection level of the lamp shell is at least required to be not lower than IP65 or higher.

In order to ensure that the LED lamp achieves the waterproof and dustproof effects of IP65, meanwhile, considering that the hiding performance requirements of the places on the lamp are high, and the quantity of the LED lamp is required to be as small as possible, lamp manufacturers generally seal the space between the upper cover and the shell by applying silica gel, so that the LED lamp panel (assembly) is subjected to 360-degree integral sealing treatment, and the dual requirements of IP protection and small quantity are met.

The current common glue filling mode is as follows: open a aperture on the plastic bag that is equipped with silica gel, operating personnel extrudees the plastic bag and makes silica gel flow out and paint the position that needs the encapsulating sealed, and this kind of mode machining efficiency of pure manual encapsulating is very low to operating personnel's operating capability requires very much, needs experienced personnel to accomplish the operation, otherwise causes the encapsulating inhomogeneous easily. The product quality processed by glue filling is unstable, and a large amount of silica gel is wasted in production practice, so that the production cost is increased.

And the encapsulation transparent silica gel inevitably causes serious drift problem to the LED color temperature once covering the light-emitting surface of the lamp bead, shows the rule of consistency, and the warm white LED color temperature drift amount of low color temperature is less, and the cold white drift amount reaches more than 10000K, and the LED color temperature drift amount is great. Because the encapsulation transparent silica gel covers the light-emitting surface of the lamp bead, the total reflection position of the blue light is changed, and the totally reflected blue light can not effectively excite the fluorescent powder for the second time, thereby having great influence on the integral color temperature and explaining the phenomenon of great drift difference generated from warm white to cold white.

The machine still commonly used in the market carries out automatic encapsulating, all goes out the route of traveling of gluing through the play volume of control glue and machine, avoids the LED subassembly to have the position of LED lamp pearl, thereby prevents that glue from covering the lamp pearl light emitting area and influence the LED colour temperature and cause the drift problem. However, the mass production is inevitably affected, and the problem of low efficiency is caused, because the lamp panels of a plurality of LEDs realize surface illumination of the LEDs, most of the LEDs are distributed in a ring shape.
